Executive Summary
This report is a record of activities relating to the prevention and control of healthcare
associated infection (HCAI) in Northern Lincolnshire and Goole NHS Foundation Trust
during the year April 2018 to March 2019.
The main focus this year has been to continue the work around Gram negative reduction
and antimicrobial stewardship. There has also been targeted surveillance using a modified
Point Prevalence Surveillance toolkit to help capture early deviations from best practice and
instigate corrective measures as required. The team have worked closely with facilities
colleagues to revise the deep cleaning program, refresh the cleaning products and
implement the use of disposable curtains.
There have been a number of achievements in the past twelve months, which include:
Performance
Influenza vaccination of >78% of frontline workers
No Trust apportioned MRSA bacteraemia for 18 months
Peripheral cannulae associated phlebitis remains within acceptable range
The appropriate use of high risk antimicrobials remains a challenge but progress
made.
5 lapses in care / practice associated with C.difficile infection from cases reviewed
which is a reduction from previous year.
21 cases of Hospital Onset Healthcare Associate C.difficile cases compared to 39
last year which signifies over 43% reduction.
Development of KPI feedback mechanisms for frontline staff e.g. IPC dashboard
Governance
Availability of real time IPC ward data for clinical settings e.g. Alert organisms
Development of an IPC WebV database.
Training / Education
IPC Conference day well attended with external speakers.
Link practitioner days well received although staff having difficulty in attending.
Updated the Antimicrobial website to help adherence with related policies.
Page 6 of 52
Areas for further improvement and support include:
There remain a number of challenges for the Trust that need to be considered going forward.
The lack of single rooms across the trust is being addressed at DPOW through the opening
of A1 and reconfiguration of the C floor wards. However SGH has lost 11 single rooms due
to closure of the Coronation block wards. This lack of single rooms impacted significantly
over the winter period and impeded the management of influenza cases efficiently. The
closure of A1 post winter is impacting on timely isolation of patients with loose stools. This
may also impact on the ability to achieve the revised C.difficile trajectory for 2019/20.
The lack of Consultant Medical Microbiologists onsite 5 days a week continues to impact on
the delivery of a proactive service with antimicrobial stewardship ward rounds. The use of IV
antimicrobials needs reducing as showing at 50% at present.
The Trust is still awaiting the purchase and installation of MALDI-TOF within microbiology to
help speed up culture results and help guide appropriate antimicrobial prescribing. This has
been an ongoing issue for the last 3 years and impacting on the ability to reduce use of high
risk antimicrobials in a timely manner.
Poor attendance at IPCC which makes it very difficult to involve divisions in the planning and
review of proposed workstreams and share lessons.
Improve the uptake of influenza vaccination in frontline workers especially nurses and
medical staff, although CQUIN was achieved.
Increase adherence with antimicrobial Start Smart and Focus. To help achieve an overall
reduction in antimicrobial consumption and meet the new CQUIN targets re urinary tract
infection in >65years of age.
Delays in deep clean programme due to operational pressures especially on the DPOW site
increases the risk of dissemination of infections such as C.difficile. This continues to be
problematic despite escalation.
Better management of invasive devices such as peripheral venous catheters e.g. early
removal. This is being picked up in the Point Prevalence Surveillance now undertaken 4
times a year.

Introduction
This report is a record of activities relating to prevention and control of healthcare associated
infection (HCAI) in North Lincolnshire & Goole Hospitals NHS Foundation Trust during the
year April 2018 to March 2019. Healthcare associated infection remains a top priority for the
public, patients and staff and remains one of the Trust’s strategic objectives. Avoidable
infections are not only potentially devastating for patients and healthcare staff, but consume
valuable healthcare resources and impact on antimicrobial resistance pressure. Investment
in infection prevention and control remains both necessary and cost effective.
The purpose of this report is to inform patients, public, staff, the Trust Board of Directors,
Council of Governors and Clinical Commissioning Groups (CCG) of the infection prevention
and control work undertaken in 2018-19 and provides assurance that the Trust remains
compliant with the Health and Social Care Act 2008: code of practice on the prevention and
control of infections and related guidance (Department of Health, 2015). This report is
structured using the criteria in the Health and Social Care Act 2008 – Code of Practice for
Health and Adult Social Care on the Prevention and Control of Infections and related
guidance which sets out the criteria against which a registered provider’s compliance with
requirements relating to cleanliness and infection control will be assessed by the Care
Quality Commission (CQC).
Infection prevention and control is the responsibility of everyone in the healthcare community
and is only truly successful when everyone works together. Success is the product of
everyone getting everything right first time, every time. This annual report shows how we are
performing, where we do well and where we would like to do better
1. Systems to manage and monitor the prevention and control of infection. These
systems use risk assessments and consider the susceptibility of service users and
any risks that their environment and other users may pose to them.
Infection Prevention and Control Workforce arrangements
The Trust’s arrangements for the prevention and control of infection are contained within the
document, Infection Prevention & Control Strategy: Overview of the Trust Approach and
Arrangements for Infection Prevention & Control [IC/SP3], which is held by the Directorate of
Governance & Assurance/Trust Secretary. This document details the responsibilities of
various parties within the organisation and their governance and management
arrangements. While the Chief Executive has the final responsibility for all aspects of
infection control, the functional responsibility lies with the Director of Infection Prevention and
Control (DIPC) who is currently the Director of Nursing who took over this role from the
Medical Director in January 2019. The deputy DIPC for IPC oversees the day to day
activities of the IPC team and delivery of the IPC Strategy 2016-19
incorporating the annual work plan.
The number of consultant microbiologists available within PathLinks
continues to have challenges with recruitment. This has left the
availability of onsite consultant microbiologists severely stretched

The infection control service is provided 7 days a week with an on- call service available to cover the weekends and Bank holiday periods. All nurses who provide on call advice service have completed a programme of study and are experienced infection prevention and control specialists. There is also 24/7 consultant medical microbiologist cover through Path Links.
Infection Prevention & Control Committee
The Trust’s Infection Prevention and Control Committee, was a formal sub-committee of the
Trust Board of Directors however a decision was made to revert back to a standalone
committee that reports to the Quality and Safety committee. The IPC committee oversees
and directs all infection prevention and control activity in the Trust, is responsible for
ensuring appropriate implementation of national guidance and that infection prevention and
control policies are in place, regularly reviewed and compliance audited.
The annual infection control programme and IPC strategy are endorsed by this committee
and updates are received on a periodic basis. The committee membership includes
representatives from Occupational Health (co-opted), consultant microbiologist, Senior
Infection Prevention and Control nurses, senior divisional nurses or representatives,
Consultant Pharmacist, Antimicrobials, CCG representatives, Estates / facilities, medical
director or deputy and others co-opted as required. The attendance at IPCC has been
disappointingly poor during the year making cascade of information difficult. In order to
improve engagement with clinical colleagues it was decided to merge the IPCC with the

antimicrobial CQUIN group as the content was related. Unfortunately, the antimicrobial
CQUIN group was also poorly attended by clinicians as such this has been escalated to the
Medical director to help resolve this issue. A refresh of the committee is anticipated with a
review of the Terms of reference.
Surveillance of Healthcare Associated Infection
One of the main elements of Infection Prevention workstream is undertaking active
surveillance. Surveillance is more than just the recording or reporting of infections. Data is
collected in accordance with strict definitions and protocols to ensure consistency. Some
surveillance data are only reported internally and other data are reported externally either as
part of mandatory or voluntary surveillance schemes. However, the most important element
of surveillance is feedback to clinicians. Feedback prompts review of, and where necessary,
planned improvements to clinical practice. There are a number of mandatory surveillance
activities that are routinely undertaken to meet Public Health England requirements and is
growing year on year with increasing demands on the team.
MRSA Bacteraemia
Nationally, there remains a zero tolerance for preventable MRSA bacteraemia cases. Thus,
once again the Trust had a target of zero avoidable hospital-acquired cases. As in previous
years, every case of MRSA bacteraemia must undergo a rigorous Post Infection Review
Process to help identify any obvious root causes and learn lessons. I am pleased to report
the Trust has not identified any hospital onset MRSA bacteraemia cases for 18 months.
Table 1 MRSA bacteraemia cases since 2006
Year Trust-apportioned Total
2006/2007 29 (60.4%) 48

Overall the Trust has performed very well compared to many other Trusts within the region
as can be seen in the Yorkshire and Humber PHE data below.

Blood Culture Contamination Rates
Blood culture is an essential investigation required in patients with suspected sepsis. It is
essential a blood culture sample is taken using an approved procedure to reduce the risk of
skin contamination. Blood culture contamination rates have been consistently around 6%
each month but the aim is to achieve a rate of 3% or below. A system has now been
developed whereby contamination levels are monitored trust wide and disseminated to
clinicians as well as being available on the HUB. One of the key actions implemented is all
staff taking blood cultures will be checked to determine they have undergone the approved
competency training. Staff found to have consistently high rates of blood cultures reported as
possible contaminants will be referred for refresher training via the clinical skills team. A
quality improvement project has also been commenced at DPOW ECC site to establish
whether taking blood cultures from newly inserted peripheral lines contributes to the
contamination rates within this location.
Figure 2 Blood culture contamination data trust wide for 2018-19
The blood culture contamination rates remain slightly higher within the emergency care
centre at DPOW compared to SGH. There are a number of activities in place to further
explore the rationale for the discrepancies including observation and enhanced surveillance.
A number of safety huddles within ECC and admission units have been attended by IPC
staff and clinical facilitators to cascade the
message about blood culture contamination.
Additional training and education has been
developed by the clinical skills team with IPC
input. Contamination rate data is posted onto the
intranet site and cascaded to clinical leads on a
regular basis to help sustain the message.
Contamination rates from the emergency care
centre can be seen below.

Clostridioides difficile (formerly known as Clostridium difficile) Infections
Figure 4 Breakdown of C.difficile cases by ward
Clostridioides difficile infection
(CDI) remains an unpleasant,
and potentially severe or fatal
infection that occurs mainly in
elderly and other vulnerable
patient groups especially those
who have been exposed to
antibiotic treatment.
Clostridioides difficile is a
bacterium that releases a toxin
which causes colitis (inflammation of the colon), and symptoms range from mild diarrhoea to
life threatening disease. Asymptomatic carriage also occurs. Infection is often associated
with healthcare, particularly the use of antibiotics which can upset the bacterial balance in
the bowel that normally protects against C. difficile infection. Infection may be acquired in the
community or hospital, but symptomatic patients in hospital may be a source of infection for
others.
The C.difficile objective guidance for 2018-19 continued the use of lapse in care as a
performance indicator. A lapse in care would be indicated by evidence that policies and
procedures consistent with local guidance or best practice were not followed.
The trust had a CDI objective of no more than 20 cases and ended the year on 5 lapses in
care and 21 hospital onset cases detected at NLaG. The number of cases identified as a
hospital acquired case (>3 days post admission) has significantly decreased compared to
the previous year by over 40% with 77% of cases identified at Diana, Princess of Wales site.
The higher number of CDI cases at DPOW is a continuous trend and may be related to a
significant number of confounding factors such as:

Greater length of stay
Frequent patient moves
Antimicrobial stewardship not optimal
Delay in deep cleaning schedules
Lack of isolation capacity
Hand hygiene facilities suboptimal (addressed with C floor redevelopment)
Medical model of care – frequent consultant changes due to ward moves.
Activity levels and staffing establishments.
The SGH site had 5 cases of CDI, Goole detected 0 cases and DPOW 16 cases. The
majority of cases occurred on medical wards, however given the movement of medical
patients between traditional surgical wards the allocation to specialty is not always clear cut
especially during winter months. The main area of concern is the poor physical environment
of the medical floor at DPOW and poor antimicrobial stewardship. The IPC team routinely
submit stool samples for ribotyping to the reference laboratory to help establish the presence
of virulent strains of C.difficile and also monitor if there is a possible relationship between
cases and no hypervirulent strains have been detected.
During the year the C floor reconfiguration has resulted in additional ensuite facilities
including single rooms. In addition, the temporary opening of A1, which has 14 single rooms
helped manage patients with loose stools more proactively. Unfortunately, A1 use has now
ceased which may have an impact on the timeliness of isolating patients with communicable
infections and hinder the deep cleaning programme.
Overall the trust is performing well compared to Yorkshire & Humber data comparing
performance based on 100,000 bed days.
Page 13 of 52
The average cost of a CDI is estimated to be around £7,000. Local data showed patients
who develop this infection had an average length of stay 6 times greater (36 days) compared
to non-infected patients (5 days).
Figure 5 Number of C.difficile cases
The distribution of cases over the year apart from September does not show any form of
trend. The increase in September is difficult to explain but could be related to the number of
senior clinicians on leave resulting in delay in review of antimicrobial prescribing.
The number of days between CDI cases is recorded. This does show an improvement
compared to last year as expected with a reduction in cases. With the opening of A1, the
days to CDI detected has improved, unsure if this is related but will certainly help.
Figure 6 days between CDI cases
Page 14 of 52
Post Infection Review
Following a case of Healthcare Onset Healthcare associated C.difficile infection a PIR is
undertaken with relevant clinical staff to ascertain if there have been any deviations from
best practice. The five lapses detected were mainly associated with the use of antimicrobials
e.g. prolonged courses. A number of PIRs have also noted a delay in the deep cleaning of
wards. Work continues to identify cohort facilities to allow this process to continue. All acute
wards should have a full deep clean a minimum of once a year, where possible incorporating
the use of UVC, however in some cases wards have been behind schedule up to 18 months.
This has been discussed at IPCC for follow up and action as required.
Some of the initiatives introduced to reduce the risk of infection including CDI.
The IPC team have been actively undertaking a streamlined version of the national PPS on acute wards. This helps to identify any issues with invasive devices, antimicrobials and infection related issues. Feedback is provided using an infographic format usually same day.
Educational roadshows to promote hand hygiene as part of the May hand hygiene awareness week.
As part of an ongoing QI project the IPC team are developing an assessment tool, using principles of the PUG (pressure ulcer) wheel. The tool will help support the Mouth care policy that has been written – with the aim to reduce lower respiratory tract infections and ultimately antimicrobial prescribing. The tool was presented at the Nursing & Midwifery conference May 2019.
Page 15 of 52
Winter roadshows preparing staff on how to deal with winter viruses such as influenza and management of infectious patients. Also emphasising the importance of good antimicrobial stewardship and the role of the nurse.
The Trust has moved across to a managed disposable curtain system. The curtains have an integrated antimicrobial coat helping to reduce the incidence of cross infection. The IPC team undertook an in-house microbiological evaluation of the curtains and they performed well compared to market competitors.
Further collaboration with facilities team saw the trust move away from traditional chemicals to a new simple to use agent proven to help reduce the environmental burden of C.difficile.
Collaboration with WebV team saw the development of a urinary catheter icon. This enables the team and others to identify the number of urinary catheters in use across the Trust and the rational for their use. The aim is to challenge their use and encourage removal as soon as possible to reduce the risk of infection.
The challenges for the next year will be keeping within the CDI objective trajectory. The new
definitions of Healthcare Onset Healthcare Associated and Community Onset Healthcare
Associated will by default allocate significantly more CDI cases to the Trust. The CDI
objective trajectory for 2019-20 has been uplifted to no more than 36 cases as a result. The
national data capture system which allocates cases to the Trust has not been modified with
the new definitions which will result in some mismatch between Trust reported cases and
national numbers. It is anticipated these definitions will increase the workload for the team
due to review of cases classed as HOHA and COHA. As part of the PIR process this
Page 16 of 52
involves the lead clinician managing the patient, Antimicrobial Consultant pharmacist,
matron, IPC representative, CCG nurse representative and patient or family member
(invited). The PIR will decide if any lapses in care / practice have occurred taking into
account prescribing and care leading up to the infection.
C.difficile allocation of cases from 2019-20
Staphylococcus aureus bacteraemia
Staphylococcus aureus is a bacterium commonly found colonising the skin and mucous
membranes of the nose and throat. Although approximately a quarter of the population carry
this organism harmlessly, it is capable of causing a wide range of infections from minor boils
to serious wound infections and from food poisoning to toxic shock syndrome. In hospitals, it
can cause surgical wound infections and
bloodstream infections. When
Staphylococcus aureus is found in the
bloodstream it is referred to as a
Staphylococcus aureus bacteraemia. The
reporting of Meticillin Sensitive
Staphylococcus aureus (MSSA)
bacteraemias became mandatory from January 2011. Prior to that only voluntarily collected
data was available.
The number of trust apportioned MSSA bacteraemias detected during the current year are
shown in Figure 7. The definition of Trust-Acquired vs Community-Acquired is based on the
positive blood culture sample being collected on or after the 3rd day of admission. All actions
taken to minimise MRSA bacteraemias will have the effect of minimising MSSA
bacteraemias. The number of cases detected deemed healthcare acquired compared to the
previous year have decreased slightly from 15 to 12. The majority of MSSA bacteraemia
cases are detected within 2 days of admission and in many cases the source is not always
obvious despite a review by the IPC team. The commonest theme, where identified, is
related to skin and soft tissue. A breakdown of the cases shows 8 were detected at DPOW
and four at SGH with 10 of the cases within medical specialties.

Gram negative blood stream infections inc E.coli.
Halving the numbers of healthcare-associated Gram-negative bloodstream infections
(GNBSIs) by 2021 is a key government ambition, announced as a key action in Lord
O’Neill’s Review of Antimicrobial Resistance (AMR.) In 2017 we saw the implementation of a
new national ambition to reduce the incidence of healthcare-associated Gram negative
bacteraemias caused by Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa by
50% (compared to baseline year April 2017 to March 2018) by April 2021. The trend of
increasing numbers of E.coli bacteraemia cases is mirrored in the national data. The
ESPAUR Report (Public Health England, 2018) notes the following:
“The proportion of isolates of Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca
and Pseudomonas spp. resistant to key antibiotics remained broadly stable between 2013
and 2017. Non-susceptibility to piperacillin/tazobactam and co-amoxiclav in E. coli appeared
to increase slightly between 2016 and 2017, as did non-susceptibility to
piperacillin/tazobactam in Pseudomonas spp.” ESPAUR, 2018.
Figure 9 E.coli resistance national trend
Page 18 of 52
Locally the number of E.coli bacteraemia cases remains a significant burden for patients.
The criteria for reporting Gram negative blood stream infections changed in 2017-18 to
incorporate Klebsiella spp. and Pseudomonas aeruginosa.
Figure 10 E.coli blood stream infections with reduction trajectory
The number of E.coli blood stream infections detected after day 2 of admission has
increased from 29 cases in 2017-18 to 51. The
number of cases detected is very dependent on
the presenting patient condition and timeliness of
the blood culture. The extreme temperature during
the spring and summer period would also have
had some impact on the number of cases
presenting with urogenital issues exacerbated by
dehydration. The Trust reported 315 cases which
is a combination of Healthcare Onset and
Community Onset cases of which 51 were
deemed Healthcare Onset (16%). As can be appreciated with this number of cases reported
with around 86% of E.coli blood stream infections detected within 2 days of admission, many
of the required interventions will require a health economy approach if a long lasting
reduction is to be made. The necessary actions should take into consideration the age
profile of these patients (Fig 11) where the average age of gram-negative patients is 73.1
years and 68.3% of gram-negative patients are 70 yrs. or over. Due to the age profile a
significant number will have numerous co-morbidities and risk factors e.g. dementia,
increasing their risk of infection. Therefore measures such as hydration, removal of urinary
catheters, appropriate diagnosis and treatment of urinary tract infections, better surgical
management are some of the key priorities for secondary and primary care.

Figure 12 Trust apportioned Gram negative cases
In addition to E.coli the Trust reports the number of Klebsiella and Pseudomonas aeruginosa
blood stream infections.
Pseudomonas aeruginosa is a Gram-negative bacterium often found in soil and ground
water. P. aeruginosa is an opportunistic pathogen and it rarely affects healthy individuals. It
can cause a wide range of infections, particularly in those with a weakened immune system.
These infections are sometimes associated with contact with contaminated water. In
hospitals, the organism can contaminate devices that are left inside the body, such as
respiratory equipment and catheters. P. aeruginosa is resistant to many commonly-used
antibiotics.
The trust detected 29 cases of Pseudomonas aeruginosa with 12 Healthcare Onset, which
was similar to previous years.
Klebsiella species belong to the family Enterobacteriaceae. Klebsiella species are a type of
gram negative rod shaped-bacteria that are found everywhere in the environment and also in
the human intestinal tract (where they do not cause disease).Within the genus Klebsiella, 2
common species are associated with the majority of human infections: Klebsiella
pneumoniae and Klebsiella oxytoca. Both species are commonly associated with a range of
healthcare-associated infections, including pneumonia, bloodstream infections, wound or
surgical site infections and meningitis
In healthcare settings, Klebsiella infections are acquired endogenously (from the patient’s
own gut flora) or exogenously from the healthcare environment. Patient to patient spread
can occur via contaminated hands of healthcare workers or less commonly by contamination
of the environment.
Last year there were 72 cases of Klebsiella with 13 Healthcare Onset which is similar to the
previous year.
A breakdown of the hospital associated E.coli cases shows the majority being detected
within the medical units such as gastroenterology ward and acute surgical ward having most
cases. However given the number of patient outliers the ward location cannot assume this is
always the correct specialty associated with the infection.
Page 20 of 52
Table 2 Hospital onset E.coli bacteraemia cases 2018-19.
Examination of the main source of E.coli infection locally in the stack chart would suggest
the urinary system and hepatobiliary are the main predisposing risk factors and this is where
targeted interventions are to be directed e.g. avoid / removal of urinary catheters, better
surgical pathways. The national picture in the infographic is not too dismilar to our local
position.
Figure 13 Common causes of E.Coli bacteraemia in cases detected at NLaG
It is acknowledged that the reduction although welcomed, much more needs to be done to
ensure the number of cases is kept as low as possible and best practice is embedded
across the whole health economy. The IPC team have attended regional workshops to

ascertain the latest evidence based practice and how this can be embedded into the Trust
where required. Given the risk factors for gram negative reduction are so generalised and as
yet not fully understood, it is important as a Health economy we adopt measures that are
within our control. All cases of Hospital Onset Gram negative infections are reviewed to
identify the source of infection if known and identify if any lapses in care / practice have
occurred. Where a lapse has been identified a review meeting is held with the ward manager
and Matron to help avoid future cases.
As a trust our rate of E.coli bacteraemia is comparible to many other trusts however we
always strive for improvement in reducing the number of cases.
Figure 14 Hospital onset E.Coli bacteraemia counts
As a Trust we reported 530 mandatory organisms on the national data capture system
excluding the influenza winter reporting. With the expansion of alert organisms reporting this
contributes significantly on the core activity of the team. Each case takes time to review and
if needed arrange follow up reviews.
Surgical Site Infection Surveillance
The Department of Health introduced mandatory surveillance of certain categories of surgery in 2004. It is a requirement that each trust should conduct surveillance for at least 1 orthopaedic category for 1 period (3 months) in the financial year. The categories are:
hip replacements knee replacements repair of neck of femur reduction of long bone fracture
The Infection Prevention and Control team in conjunction with our orthopaedic colleagues
undertake continuous surveillance of primary total hips (THR) and primary total knee (TKR)
on all three hospital sites. There has been some adjustment to the number of orthopaedic
implant surgery undertaken at SGH site due to the closure of the Coronation block for in-
Page 22 of 52
patient activity due to the detection of legionella SG1. As such the majority of elective major
joint arthroplasty surgery is undertaken at Goole and DPOW.
Table 3 Orthopaedic hip and knee replacement infection rates
Overall the infection rates remain low but due to the small denominator the infection rate can
quickly become skewed. The Trust received a letter from PHE alerting us to the infection
rate for Total Knee replacement to be above the 90th percentile, infection rate of 0.9% at
DPOW for the period Oct-Dec 2018 (n=2 out of 230 cases). When a surgical site infection is
detected a thorough RCA is undertaken to identify if there were any deviations from best
practice. In the cases reviewed there were no significant deviations from best practice
identified. As a team we undertake a very robust method of monitoring patients fully for the
whole year.

As part of the surveillance process the team also ensure theatres are adopting best practice
in accordance with the High Impact Intervention surgical site prevention bundle. Now that
sufficient data has been collected a dashboard has been produced and shared with Theatre
colleagues to ensure the high standards of practice are maintained.

CDCU post procedure infection
The Infection Prevention team were notified in August of a possible issue with surgical site
infection occurring in patients undergoing a loop recorder insertion. Four patients developed
post insertion wound leakage and commenced antibiotics by their GP or following their Out
Patient appointment review.
A small incident group was convened to establish the root cause and ensure measures put
into place to address any shortcomings. It was found the method of skin closure may have
been one of the main contributory factors and this was addressed with good outcome. No
further cases have been reported since the review.
Page 25 of 52
Influenza / Viral respiratory disorders
Influenza season is a yearly event with most cases occurring during the period of November
to March. The severity of influenza disease and impact on services is often difficult to predict
due to the fluctuating presentation of the virus.
Path Links Pathology currently
provides in house PCR
(Polymerase chain reaction)
testing for the respiratory
viruses Influenza A (FluA),
Influenza B (FluB) and
Respiratory Syncytial Virus
(RVS) from the Scunthorpe
site. Some clinical samples are
also sent to the reference
laboratory based in Cambridge
where further specialised investigations are performed.
The winter of 2018-19 turned out to be less aggressive than the previous season overall for
the Trust however there were still some significant variations across the two main sites. The
majority of patients identified with influenza were Influenza A virus with the predominant
being A(H1N1). The quadrivalent vaccine appeared a good match in terms of protection.
This was clearly visible in the almost total eradication of influenza type B detected compared
to the previous season, where it contributed up to 50% of all influenza cases.
The number of influenza cases detected at SGH site was three fold greater this year. SGH
detected 152 positive patients compared to DPOW who identified 39 patients from
December to mid-March.
Figure 16 Number of Influenza cases detected comparing 2017-18 - 2018-19 season
Page 26 of 52
The high number of cases detected at SGH site did pose some difficulties with appropriate
timely isolation of cases. The closure of the Coronation block (ward 10 & 11) resulting in a
net loss of 11 single rooms clearly added to the operational issues in managing infectious
patients safely. The IPC team were in daily contact with the operational teams to best
manage patient flow and where necessary incidence meetings were convened to manage
any bed closures. The impact of influenza was also seen within the critical care units
especially at SGH during the early phase of the season where they had more cases up to
January than in the previous 10 years. The units had guidance from the IPC team and
Consultant microbiologist.
Figure 17 Influenza cases detected on critical care units.
One of the best ways to protect vulnerable patients and front line staff from influenza virus is
the influenza vaccine. There was an expectation that organisations have to achieve a front
line worker uptake of at least 75%. NLaG achieved a respectable 78.3% uptake
in front line workers using a peer vaccination approach.
Table 5 Influenza vaccination uptake by frontline workers
Season Dr Nurse AHP/STT Support Total
2017/18 83.7% 65.5% 67.1% 80.5% 72.6%
2018/19 77% 76% 98% 75% 78%
Further work is required with improving uptake in frontline workers as it’s the best form of
defence we have in reducing dissemination of the virus. The peer vaccinator model was very
successful and this will be hopefully adopted again for the next influenza season. The top 3
peer vaccinators received a prize to thank them.

Respiratory syncytial virus – paediatric.
From October to March there were 157 cases of Respiratory Syncytial Virus (RSV) infection
detected during the year with the majority of samples taken on the paediatric unit, this is a
slight increase to the previous year. The infection causes bronchiolitis in babies and young
adults especially during the winter months. The vast majority of cases are self-limiting and
the paediatric wards are well versed in managing such cases. 76 cases were detected on
Disney ward and remaining at DPOW Rainbow.

The Intensive Care units across the trust have been utilising a VAP High Impact Intervention
developed by the IPC team. The HII is completed on a daily basis and the units will have
access to up to date key performance data to ensure staff are complying with best practice
guidance.

Page 28 of 52
Point Prevalence Surveillance
As part of the ongoing review process the IPC team began to undertake a modified version
of the national Point Prevalence Surveillance twice a year. The main advantage of utilising
this approach is that it enables the team to gain an immediate insight into the practices on
the ward re invasive devices, antimicrobial prescribing and management of patients with
infections. All patients within the ward are reviewed and staff are then provided with a verbal
resume and this is followed up with a written report usually the same day. Divisions are
provided with a dashboard (see below) that is available on the HUB site to help support any
changes in practice.
Table 6 PPS Feedback
In total there were 609 patients reviewed as part of the Point Prevalence Surveillance over 2
period during the year. The results identified a Hospital associated infection rate of 7% which
is slightly above the national average. The commonest infection was related to the
respiratory tract e.g. hospital or community acquired pneumonia. The PPS identified 53% of
patients had a peripheral cannula insitu and 74% of these had their visual infusion phlebitis
score recorded as per policy. There were 22% of patients identified with a urinary catheter
and 48% of these had a pathway in place. As part of the focused work around reducing
Gram negative infection the team have developed and implemented a urinary catheter plan
of care to ensure the device is reviewed on a daily basis to determine if still required. The
pathway was launched in September and is in the process of being embedded. The PPS
also established that around 45% of patients are receiving antimicrobials with 57% of these
being intravenously, which is a high and requires greater focus. The commonest
antimicrobial in use was co-amoxiclav and this contributed to almost half of all agents in use.
Once the PPS results are fed back to the ward staff and clinical leads, if any significant
deviations from best practice are detected the IPC team will help support the area by
working with colleagues to help support the required changes. Overall the results show there
is much work to be done by nursing and medical colleagues to help minimise the risk of
avoidable infection.

Carbapenemase-producing Enterobacteriaceae
The management of patients with an antibiotic resistant organism is an increasing priority
nationally. The emergence of Carbapenemase-producing Enterobacteriaceae (CPEs) is
predicted to pose significant challenges nationally in the near future. Carbapenem antibiotics
are a powerful group of B-lactam antibiotic used in hospitals. Until recently they have been
able to be used to treat infections when other antibiotics have failed. Emerging resistance
patterns have rendered in some cases Carbapenems ineffective. Public Health England
have issued toolkits for use in either acute or community settings to enable the early
detection, management and control of CPE. A Trust policy is in place to support and guide
staff to provide safe and effective management of patients colonised or infected with
resistant bacteria and minimise the risks of transmission in patients.
The Trust undertook over 300 tests for CPE

then isolated and screened as per policy until the result and risk assessment has been
reviewed by the IPC team.

2. Provide and maintain a clean and appropriate environment for managed
premises that facilitates the prevention and control of infections.
The Facilities Department has continued to support the work of the IPC team. The work of
the deep clean team in helping to maintain a proactive deep cleaning program is well utilised
and seen as a significant factor in helping to control the spread of pathogenic organisms.
The aim of the deep cleaning programme is to clean high risk wards / departments a
minimum of once a year but ideally twice a year. There are some difficulties in gaining
clinical access in particular on the DPOW site with some areas out of compliance by over 18
months. Whilst routine environmental cleaning will take place the importance of a thorough
synchronised deep clean programme cannot be overemphasised in helping to keep the
number of environmental C.difficile spores to a low number. There are a significant number
of acute wards at DPOW that remain out of compliance and this has been escalated to IPCC
and Quality & Safety Committee.
Facilities Service update
Improving cleanliness through a review of our existing processes and procedures was an
integral part of our business plans for 2018 – 19. Through effective ownership and support to
clinical services, we set ourselves an objective of achieving a reduction of hospital outbreaks
of infection. By delivering robust cleaning regimes, restricting and preventing the impact of
bed capacity loss for our operational colleagues, we will work with Infection Prevention &
Control to help reduce staff sickness, improve patient safety, and provide a clean, safe
environment supporting the Trust to deliver its priorities with the use of modern technologies,
innovations and practice of cleaning functions.
During 2018 – 19 the Facilities Services team have made some significant changes to
practices, improving the patient environment, introducing better cleaning chemicals, which
are safer, deliver better bug fighting properties, and are less harmful to our staff, the
environment and the estate.
Our 2018 PLACE outcomes reflected the improvements we have made against the prior
year results. Overall as an organisation we climbed from 98.40% to 99.34%, with individual
sites all scoring in the highest 99th percentile.
Our cleaning chemicals are now much simpler to measure dosing, reducing daily cleaning
tasks to just one chemical. We have totally removed the use of chlorine based products for
routine cleaning, moving forward with a regular universal cleaner, and a medical grade high
level disinfectant. Our daily universal cleaner retains potent disinfecting properties,
maintained by a change to single use cleaning cloths to maintain its efficacy as a cleaning
solution. For enhanced level cleaning requirements, our Medi-9 product is ready to use, with
a biocidal, virucidal, fungicidal capability, ready for use in high risk infectious outbreaks. This
change in chemical use and process has contributed towards a Trust reduction in prior year
C.difficile cases of 43% during 2018 - 19.
All of our wards and departments were previously furnished with linen curtains for privacy
and dignity. These curtains were in excess of 15 years old, held no resemblance to the
Page 31 of 52
décor or environment, some had damage and were simply degrading of the care
environment. The team reviewed the market, met with suppliers and working with our IPC
colleagues, identified a solution which provided a single standard for curtains. Our new
curtains are protected with a biocidal surface and are exchanged every 4 months. The
change reduced our carbon footprint by removing the need to launder linen curtains, whilst
off-setting cost efficiencies through removing the need to change curtains for non-other than
the highest risk infectious outbreaks. This also reduced time spent hanging heavy curtains,
on an almost daily occurrence, improving the occurrence for manual handling on our teams.
The change also reflected in a positive response to the care environment, and directed the
responsibility of ordering and exchanging the curtain stock to the Facilities Services
department.
Our continued development also aims at reviewing the equipment provided to our dedicated
teams. Technology advances in disposable products including micro-fibre, meaning less
need for chemicals, with even a consideration of none for daily cleaning being possible,
whilst still achieving the quality we require. Future plans will include a review of our cleaning
trollies, mopping processes and chemical use, delivering further efficiencies in labour and
chemical use and cost.
Enabling us to stay ahead of the advancements in cleaning is our two Facilities Services
Managers, Michelle Smith and Karl Cliff. Having served as members, both are now
contributors and leaders within the Association of Healthcare Cleaning Professionals
(AHCP). Michelle represents as the Yorkshire & Trent Branch regional chair, with Karl
representing the group at the National Council of Members forum. This additional role
provides a great level of awareness and forms key relationships for networking with
likeminded healthcare professionals alongside service and industry leads. This engaging
profile will ensure our Trust is well placed and informed to continue our aim of providing the
highest level of safe, quality, effective cleaning principles. (summary produced by Keith Fowler – Head of facilities)
Ward Environmental Audits (Flo)
The average scores per section are highlighted below. The main areas for future
improvement are generally associated with environmental fixture and fittings such as floor
and wall condition. Any items that are potential patient safety concerns are dealt with by
estates and facilities in a timely manner.
Table 7 Flo Audit Scores
The trust has an extensive program of environmental audits using
the Flo audit tool on WebV. The IPC team undertake a minimum
of one Flo audit per year to quality control the process. The
Quality Matrons undertake the Flo audits on a Monthly to
quarterly basis depending on the scores achieved. The ward
Page 32 of 52
sisters / charge nurses undertake monthly - quarterly audit schedules depending on previous
results. The main issues with the general environment are related to maintenance issues
e.g. damaged floors or walls which will be logged with estates.
The IPC team have over the last year developed a dashboard which allows interrogation of
the Flo audit scores across sites, wards, divisions and groups of staff. The audit scores were
reviewed at the Matrons forum and nursing metrics panel to identify any trends and actions
required. Due to the issues in extracting the audit scores and maintaining the issue log, the
Flo audit tool will be phased out and replaced with a ward assurance tool (15 steps) that
incorporates key IPC questions. In addition the IPC team are exploring the development of a
bespoke audit tool just for the IPC team to ensure generic standards are maintained when
the Flo tool is archived.
The latest Patient Led Assessments of the Environment (PLACE) scores (see below)
suggests the trust has significantly improved from the previous year and is now above the
national average for cleanliness and condition/appearance.

Decontamination
A member of the Infection Prevention and Control team attends the decontamination group.
This group oversees decontamination issues including the function of the Synergy run
HSDU. The committee is responsible for ensuring that reprocessing systems are revalidated
as required and dealing with problems by exception. It serves as a conduit between
equipment reprocessing departments and the IPCC.
Water Safety Group
The Deputy DIPC and Consultant microbiologist are members of this group to help ensure
relevant guidance is adopted to help reduce the risk of waterborne infections such as
Pseudomonas and Legionella. The group has implemented a number of standard operating
procedures to ensure the daily flushing of little used outlets and their correct cleaning /
maintenance including the use of L8 guard.
The SGH neonatal unit (augmented care) continues to have the Point of Care filters on the
majority of its wash hand basins due to intermittent positive counts of either Pseudomonas
aeruginosa or Legionella species. The Coronation block at SGH continues to be out of action
for inpatient overnight stay activities due to the detection of legionella in multiple outlets. This
has resulted in the closure of ward 10 & 11 and Theatre F&G. A decision as to the future use
of this block is still to be fully concluded, in the meantime legionella control measures are in
place.
Page 33 of 52
Pseudomonas Water Testing
In 2012 the Department of Health issued national guidance for managing Pseudomonas
within the water system of hospitals in-particular the augmented care units. These high risk
units have a regular water check depending on results and where Pseudomonas or
legionella species are identified discussion takes place with the IPC team on measures
required to mitigate the risk. There is a robust ongoing program within the clinical settings to
ensure flushing is undertaken within little used outlets and that wash hand basins are used
appropriately. The L8 guard reporting system is working well and generally achieving a good
level of flushing compliance. In order to support the appropriate use of clinical wash hand
basins (WHBs) a new adhesive poster has been placed next to WHBs within high risk units
to reinforce the message.
3. Ensure appropriate antibiotic use to optimise patient outcomes and resistance
Antimicrobial Management
As part of the action plan developed
following the antimicrobial users audit
undertaken where users stated they
would like easier methods to access
information, the IPC team and consultant
antimicrobial pharmacist put together a
SharePoint website and this was
recently updated. This is broken down
into common systems for ease of
access. The feedback has been
excellent.
The IPC nurses have commenced a number of Start Smart and Focus audits across the
wards to ensure that best practice is adopted when prescribing antimicrobials and the
rationale for each agent is clearly documented. This together with the work of pharmacy
colleagues has seen a gradual improvement in the appropriate use of antimicrobial agents
including Meropenem. The progress of prescribing certain high risk antimicrobials is tracked
using Statistical Process Control charts and additional information is also available via the
antimicrobial dashboard.
4. Provide suitable accurate information on infections to any person concerned
with providing further support or nursing / medical care in a timely fashion.
Patient Information
The trust has an IPC www website with information for the general public. There are a
variety of guides for common healthcare associated infections.
Page 34 of 52
The intranet HUB has a multitude of information leaflets for patients that can be quickly
printed off by staff as required as well as quick reference guidance on ‘how to’ manage
patients with infections.
5. Ensure that people who have or develop an infection are identified promptly
and receive the appropriate treatment or care to reduce the risk of passing on the
infection to other people.
MRSA colonisation
Not all MRSA positive results are found in blood cultures. The bulk of MRSA isolates come
from routine wound swabs and from swabs taken specifically to look for the presence of the
organism (screening swabs). Most patients, from whom the organism is isolated, are not
infected but rather merely colonised, i.e. harmlessly carrying the organism. It is very difficult
to look at the raw data and determine how many patients are in fact infected but the rule of
thumb is that infections account for less than ten percent of isolates.
The MRSA screening criteria within the trust was modified in 2014/15. This was in
accordance with national recommendations where targeted screening rather than blanket
screening was encouraged. If an MRSA colonisation is detected within a high risk
environment a rapid review is undertaken to ensure best practice is maintained and any
lessons learnt are shared.
Patients with Unexplained Diarrhoea
As part of the C.difficile reduction strategy the IPC team monitor patients who have had a
faecal sample submitted to the laboratory for suspected infection. One of the main key
performance indicators is patients presenting with type 5-7 stools should be isolated within 4
hours. In approximately 85% of cases this was achieved. Due to the limited number of single
rooms currently available across the main hospital sites, especially at SGH this will continue
to pose challenges especially during the peak winter season. Going forward new
refurbishment plans will have a minimum of 30% isolation capacity to help meet current
demands and this is evident in the C floor redesign.
Page 35 of 52
The IPC team also review whether the stool sample submitted is deemed appropriate based
on clinical information. Staff are given feedback if samples are deemed inappropriate to help
improve practice and reduce pressure on single rooms.
Figure 20 Patients with diarrhoea and time to isolation
Outbreaks
Outbreaks occur when there are two or more linked infections which may or may not be
preventable. Usually, these events are, by definition, unpredictable. There may be a
heightened alert for outbreaks of organisms with a typical seasonal activity such as influenza
and norovirus, or alternatively there may be an international alert as for Ebola Fever. The
Infection Prevention and Control Team may become aware of incidents and outbreaks
through formal schemes, e.g. structured ward liaison or laboratory based surveillance, the
Trust electronic incident reporting system and audit, or through informal routes, such as
unusual patterns observed and reported by an individual in the Trust. Early ascertainment is
key to detecting and acting on incidents and outbreaks to minimise adverse outcomes.
Norovirus is a common cause of viral gastroenteritis, characterised by rapid onset of nausea,
vomiting and diarrhoea. The virus is easily transmitted by direct contact with an infected
person, contact with contaminated surfaces or objects or consumption of contaminated food.
In preparation for the norovirus and influenza season, the IPC team undertook a number of
roadshow sessions to raise awareness and help staff to identify optimal methods for
managing patients with viral gastrointestinal symptoms and those with suspected influenza
symptoms.
The number of full ward closures due to virus related infections reduced dramatically from
the previous year from 15 to 2. The norovirus season has been less severe this year which
would have helped.
Page 36 of 52
Figure 21 Patients and staff affected with viral suspected gastroenteritis
The two ward closures this year were related to the dissemination of Influenza A virus. A
small incident group meeting was held to discuss control measures and lessons learnt which
was around failure to isolate symptomatic patients and inappropriate use of face masks.
6. Ensure that all care workers are aware of their responsibilities in preventing
and control of infection.
Hand Hygiene
Hand Hygiene remains a fundamental component in the prevention of nosocomial infections.
The IPC team continue to promote hand hygiene compliance incorporating the WHO five
moments tool. Hand hygiene compliance including bare below the elbows is an expectation
for all clinicians. Ward staff continue to record opportunistic hand hygiene observations on a
monthly basis and these are supplemented by IPCN observations to provide some quality
assurance. Areas that are found deficient are provided with a feedback plan and remedial
actions worked through with the sister / charge nurse and Matron.
A WebV hand hygiene App was launched in the last quarter of the year allowing staff to use
the smart phones on wards / depts. to record compliance. The App has been well received
by staff as it makes the process much easier and also incorporates a count of observations
completed. Overall hand hygiene compliance remains good.

6. Provide or secure adequate isolation facilities
Isolation Facilities
The C floor wards at DPOW are currently undergoing a
significant Capital development scheme. When completed the C
floor, medical wards will have an additional 7 single rooms with
ensuite facilities available. This has also been boosted by utilising
A1 which has 14 single rooms into the scheme and proved
particularly useful during winter to help manage patients with
suspected winter viral infections. The main concern with DPOW
is the lack of utilisation of A1 on a more regular basis when it is ideally suited to facilitate
deep cleaning programme and management of patients with communicable infections.
As previously mentioned the SGH site now is more vulnerable due to the closure of Ward 10
and 11 with a net loss of 11 single rooms. The lack of isolation capacity is highlighted on the
Board Assurance Framework as a risk which may impact on the overall number of C.difficile
cases and risk of cross transmission.

7. Secure adequate access to laboratory support as appropriate.
Microbiology Laboratory
The Path Links Microbiology laboratory continues to work closely with the IPC team, to
ensure appropriate testing of samples and rapid communication of results, particularly with
regard to C difficile, norovirus, MRSA screening and other “alert” organisms. Laboratory staff
will be joining members of the Scunthorpe ICPN on a few ward rounds over the coming
months to develop their understanding of the pressures and needs on the team, and how the
laboratory can actively help to support and address these.
The Microbiology laboratory continues to review how can it assist the work of the ICPN
through introduction of new rapid techniques with new technology imminent in the serology
and molecular laboratory.
The Microbiology laboratory has had a recent UKAS accreditation surveillance visit in March
and have just received a very positive report from the Assessor Team.
8. Have and adhere to policies, designed for the individual’s care and provider
organisations, that will help to prevent and control infections.
Infection Prevention and Control Policies
There are an extensive number of policies, guidelines and how to documents that are
maintained by the IPC team in a timely manner. Recent policies updated can be seen below.

9. Have a system in place to manage the occupational health needs of staff in
relation to infection.
The Occupational Health team have played a pivotal role in helping the trust achieve a
respectable overall vaccination uptake with strong support from the IPC team and peer
vaccinators. There is an accidental inoculation steering group that meets to review any
incidents and how interventions can be implemented to reduce risks for staff and patients /
visitors. A member of the IPC team is a standing member of this group.
The Occupational Health Team were closely involved in a Brucella exposure incident
occurring in the laboratory. Staff deemed as exposed were closely followed up and clinical
samples taken to ensure any transmission was picked up early and treated effectively. There
were no cases of cross infection detected from this exposure.
Training and Education
The IPC team continue to make education of staff one of its key priorities. There are a wide
variety of educational portfolio materials available for clinical and non-clinical staff to help
maintain their mandatory training requirements.
The materials include:-
Surewash machines
Workbooks for clinical and non-clinical staff
Link practitioner programme
Ward based training
Care Camp
Induction
Clinical updates
Road shows with interactive quiz e.g. Antibiotic awareness week

To assist with the influenza campaign a myth busting slideshow was integrated onto the
Surewash system with great success.
Over 6000 members of staff have undertaken some form of IPC training.

IPCN
Overview
2018/19 has been another year of change for the Community Infection Prevention & Control
team. The team remains embedded as a sub set of the Acute Trust IPC team, with dual
input across both acute and community interfaces in the transitioned provider only role, and
the team continues to deliver the IPC service at Goole hospital, which includes the Neuro
Rehabilitation Centre now managed by the Trust.
The team formerly consisting of a 1.0 wte Band 7 CNS IPCN and a 0.8 wte Band 3 AHCA
IPC has seen a reduction of 0.4 wte in the Band 3 role; sequestered time to SSI prevention
strategy now sits within the acute team, this off sets centralisation of the provider community
teams to distinct hubs; in effect reducing the number of community environments for auditing
in the current financial year.
However with the retirement of the commissioning IPCN in December 2018, support to
commissioned services has notably increased. At the time of writing this report there is still
no acknowledged appointee into this role although active recruitment has commenced.
Representation of infection prevention & control service provision continues to be
demonstrated with attendance/input at monthly Community & Therapy Governance
meetings. Following the change in leadership to the Community Divisional Head of Nursing
in this year, the stand alone Community Managers IPC meeting content has been
incorporated within the terms of reference for the governance group. This has cemented
ownership and acknowledgement of on-going challenges/ emerging threats related to
infection prevention and control. Minutes from this meeting including actions and issues
continue to be forwarded to the Infection Control Committee and are available to view via the
Hub.
Commitment to mandatory training for the Community & Therapy group continues, taking
the form of scheduled IPC facilitated offerings and additional mop up sessions delivered at
Community and Therapy bases on an adhoc basis, with complimentary learning options
available via the ‘Sure wash’ system.
Current community and therapy services IPC training figures stand at 84% inclusive of
yearly/no renewal and 3 yearly face to face requirements. Further, data interrogation
substantiates a 93% compliance rate for 3 yearly face to face training which remains above
the required average.

Audit
As in the previous year, two distinct community focused audit tools are in use. The
community version of the Trust Frontline Ownership audit tool, available on the WebV
system is completed quarterly by the Therapy group. If a score less than 82% is achieved
then audits are increased to monthly, until the identified issues are resolved. The Community
& Therapy IPCN validation tool functional via WebV is also used to record all validation
audits undertaken by the Community Infection Prevention & Control team.
The Community nurses audit, is also accessible this year via WebV with results data
available within the IPC dashboard on the Hub. The IPCN validation audit on this platform to
complement this remains outstanding.
Hand hygiene audits are recorded annually on OLM as a practical assessment for all
Community & Therapy staff. Monthly point of care audits are requested of those staff groups
in group clinical environments; namely the chronic wound management team, podiatry
teams, MacMillan Home Health care teams and Dental clinics. These audits are available to
view via the IPC hub dashboards.
The re launching of the Catheter passport and associated Catheter pathway are integral in
this year’s evaluation of the Trust Gram Negative Reduction plan. Collaboration with the
community Continence service is ongoing to achieve this within community settings.
The Community focus for the ‘Oral care project’, jettisoned in the previous year, eventually
launched in March 2019.A change in the originally appointed care home became necessary
and version 2 which is underway is due to complete early within the coming financial year .
The service improvement project, proposed by the Lead Infection Prevention & Control
nurse (looking to standardise disinfectant wipes across the Trust) in the previous year has a
been evaluated and accepted into practice by the Assisted Living Centre Community
Equipment Store .
Community & Therapy Link Practitioner Forum
The full study day format (offered twice across site as in the previous year) continues in
2018/19. The numbers in attendance for Community & Therapy staff as shown in Table 1
below continue to fall in comparison to previous years. A disappointing reduction of 26
attendees compared to attendance of the quarterly meeting format of 2015/16. The singular
study day appears to work very well for Hospital based staff but does not fit so well with
community workers and their revised way of working. Although the sessions evaluated well
this format fails to provide the necessary support and timely information to enable the
workers to ultimately fulfil their link role adequately. A Newsletter/formal updating emails are
to be considered going forward.

Decolonisation Service
The established decolonisation clinic, originally commissioned to provide decolonisation
treatment to North Lincolnshire patients’ identified as MRSA positive from admission
screening with results available post discharge continues into this financial year.
Unfortunately the service no longer has capacity to offer the previous MRSA/MSSA
screening for North Lincolnshire residents who access healthcare out of area and require
screening and possible decolonisation treatment prior to elective clinical
intervention/surgery. As evident in table 2, the yearly comparison data shows a steady
decline in patient numbers using the decolonisation service .This is consistent with the return
to targeted screening in the acute Trust(s) following the 2015 revised screening guidance.
This is also seen as the trend for Out of area accesses which have also fallen.

Infection Risk Assessment Tool
The scheduled review of this tool which concluded in September 2018 highlighted a
disproportionate weighting of patients with chronic conditions which scored highly on the
assessment but which would not benefit from early IPC intervention. Acute high risk cases
which were the proposed group for capture were not readily identified. It was therefore
agreed within the governance forum that the risk assessment tool would no longer meet a
mandatory criterion and that future referral modes for IPC intervention would be established
via clinical assessment.

Activity and Engagement
Global Hand Hygiene week with Community Services
The main priorities for 2019/20 will be to continue working with Commissioners and other
care providers to help tackle the Gram negative reduction ambition.
Review the decolonisation service with commissioners to ensure patients are provided with a
timely and local decolonisation service.
Look at other ways to provide staff and link practitioners with up to date information and
updates.
Continuing work with estates team to review the community properties are ‘fit for purpose’ for
North Lincolnshire community staff.
Implementation of the Oral care policy within community services.

Appendix 2 -Antimicrobial Stewardship
Promoting optimal antimicrobials stewardship is the primary role of the Consultant Pharmacist, Antimicrobials, who works closely with Pharmacy staff and the Infection Control Team and with clinicians Trust-wide on this issue.
Slowing the development of micro-organisms resistant to antimicrobials is a national and international priority, with relevant guidance and mandatory actions being issued by organisations such as NICE (NG15 and associated Quality Standard; Antimicrobial stewardship: systems and processes for effective antimicrobial medicine use) and the national Antimicrobial Resistance CQUINs: CCG1a, Lower Urinary Lower Urinary Tract infection in older people and CCG1b, Antibiotic Prophylaxis in Colorectal Surgery. Good antimicrobials stewardship is key to achieving these actions, as the pipeline for the development of new antimicrobials has slowed significantly and is lacking in the discovery of new classes of antimicrobials:

CQUIN Achievement
The Antimicrobial Resistance and Sepsis CQUIN was monitored and actioned by the Trust’s Specialist Nurse for Sepsis and the Consultant Pharmacist, Antimicrobials. In 2018 – 19, Part 2c (antibiotics review within 72 hours) was achieved, with 100% of prescriptions audited having been reviewed within this timescale. Steady progress with this was made over 2018 -2019, as shown by this chart on the PHE ‘Fingertips’ website (NLaG trend, pale blue):
Page 50 of 52
However, we were less successful in meeting some of the sub-criteria within those reviews and particularly, performing IV to Oral Switch, as one of those review decisions. In order to raise awareness of this option amongst clinicians, a member of the Pharmacy staff began a project to provide wards and other clinical areas with an IV to Oral Switch decision-assisting algorithm and suggested choices of suitable oral antimicrobial agents, when IVOS is indicated. That work is ongoing.
In terms of Part 2d, consumption, we are higher than the average non-teaching Trust, in terms of our antibiotic consumption per 1,000 admissions and were above our target consumption value by ~31%.
We achieved our target reduction of Piperacillin / tazobactam prescribing, being lower than the non-teaching Trust average consumption, but not that for the carbapenems.
However, the Trust has done a lot of work to reduce the prescribing of meropenem and ensure that it is appropriate, with good success:
Page 51 of 52
Antimicrobials Prescribing Strategy
The Consultant Pharmacist, Antimicrobials maintains and updates the Trust’s Antimicrobials Prescribing Strategy every three years and its associated action plan annually, so that local actions reflect the requirements of national and international strategies and aim for optimum Antimicrobials Stewardship.
It covers:
Monitoring of and interventions on antimicrobial resistance.
Examining the influence of antimicrobials use, as a risk factor for Hospital Onset, Healthcare Acquired Infections.
Further risk assessment of activities involving antimicrobials use.
Maintenance of Trust Antibiotic Formularies and Prescribing Advice.
Maintenance of the Trust’s Antimicrobials Steering Group.
Incorporation of the principles of good antimicrobials stewardship into the Trust’s electronic Prescribing and Medicines Management System.
Contribution of appropriate antimicrobials use to the management of sepsis.
Education and training on good antimicrobials stewardship, for all relevant Trust staff.
Information for patients and carers.
Antimicrobials Guidance and Review
The Consultant Pharmacist, Antimicrobials provides these functions in a number of ways:
Participation in the review, maintenance and development of the Path Links Antimicrobials Formulary and Prescribing Advice, to ensure that it is fit-for-purpose locally and also meets national guidance, such as the NICE guidance items released last year, on the management of infections.
Antimicrobials ward rounds in specific areas (on the Trust’s Critical Care Units), in conjunction with the Consultant Microbiologists.
Provision of detailed antibiotics history reviews for patients identified as Hospital Onset, Healthcare Acquired infections and participation in post-infection reviews of those patients.
Page 52 of 52
Provision of Specific Process Charts (SPCs) and additional information to Divisional Governance Groups and Associate Medical Directors, for consideration of and action, as necessary on, local antimicrobials consumption trends.
Antibiotic Audits
The Consultant Pharmacist, Antimicrobials arranges or conducts appropriate antibiotics audits, to power the Trust’s antibiotics dashboard and also provides expert advice on the application and successful completion of any local and national audits, enabling successful compliance with, for example, Antimicrobials Resistance National CQUINs.
Additionally, the Infection Control Team conducts twice-yearly point prevalence surveys, examining antibiotics prescribing quality standards, the use of invasive devices and the management of patients with infections, with relevant feedback to Ward Consultants and Nurse Managers.
Education and Training
Training on Antimicrobial Stewardship and antimicrobials medication is provided in a number of ways:
On-line mandatory training.
Monthly Antimicrobial Stewardship session delivered by the Consultant Pharmacist, Antimicrobials, on new doctors’ induction sessions.
“Key messages on antimicrobials prescribing;” Antimicrobial Stewardship sessions on the FY1 doctors’ core training programme.
Pharmacists’ monthly Antimicrobial Stewardship sessions, with CQUIN updates and antimicrobials case studies.
Annual Grand Round presentations for doctors on both main sites, on Antimicrobial Stewardship, to coincide with World Antibiotics Awareness Week and European Antibiotic Awareness Day.
Pre-registration Pharmacist activity, during World Antibiotics Awareness Week and European Antibiotic Awareness Day, including running stands to communicate with Trust staff and patients, on the prudent use of antibiotics.
Delivery of influenza and pertussis vaccination training sessions for Trust peer and patient vaccinators.
Patient Information
Patient information Leaflet IFP-0755, “Antibiotics Information for Patients and Carers,” is kept up-to-date.
Specific Projects
Dedicated prescription charts: Parenteral Vancomycin Inpatient Prescription, Administration and Monitoring Chart and a revised Once Daily Gentamicin Prescription Chart and associated guidance, have both been launched this year.
