BackgroundLogan Hospital is a 440 bed hospital for one of the fastest growing regions in Queensland. It is one of five hospitals in the Metro South Hospital and Health Service, the largest Hospital and Health Service in South East Queensland that provides healthcare to a population of more than 1 million people, 23% of Queensland’s population.
InterventionStriving to achieve best practice is implicit in the definition of a multidisciplinary evidence based clinical pathway in which the different tasks of professionals involved in patient care are defined, optimized and sequenced. Clinical pathways have been shown to effectively manage and improve quality in healthcare.6
A fully integrated clinical pathway for the management of CAP in immuno-competent adult patients was developed under the leadership of an Infectious Diseases physician in collaboration with clinicians from Respiratory, General Medicine, Emergency Department (ED) and Intensive Care; as well as input from Nursing, Pharmacy and Allied Health. The pathway is designed to replace the inpatient progress notes and follows the patient journey from presentation and initial assessment in ED to day four of their admission. The tasks of each health professional are defined, optimised and sequenced. Also included is a guide to clinical assessment, a severity assessment tool and a treatment algorithm for empirical antibiotic management.
In addition to the pathway itself, patient information leaflets were developed to assist with patient education and support the early discharge of patients directly from ED where appropriate. To facilitate appropriate antibiotic prescribing at discharge, CAP “pre-packs” were introduced into the ED imprest.
ResultsThe Baseline demographics of our patient group did not differ significantly between the years audited.

The drive for this program came from the prescribing of antibiotics outside recommended guidelines for the treatment of Community Acquired Pneumonia (CAP) that was noted as a result of Antimicrobial Stewardship (AMS) activities at Logan Hospital.
Community acquired pneumonia is a common condition with significant morbidity and mortality especially in the elderly. Studies in the United States report a 12% death rate associated with patients admitted to hospital with CAP. Patients who survive hospitalisation are vulnerable to readmission with a resulting economic impact of CAP estimated to be $12.2 billion dollars in 1996-98, 90% of which is attributed to hospital care1.
Inappropriate selection of antibiotics in the management of CAP has frequently been reported in the literature, including within the Australian setting2,3. Adherence to evidence-based guidelines can have a profound impact on patient outcomes and healthcare costs4. Guidelines have been shown to improve short-term prognosis in patients with severe CAP who require ventilation in hospital. AMS efforts have demonstrated decreased use of broad spectrum antibiotics, earlier switch from intravenous to oral therapy, with overall shorter duration of therapy and decreased length of stay in hospital5.
Clinical pathways have been shown to improve quality in healthcare.6 Clinical pathways have been shown to be effective tools in the management of CAP, encouraging greater adherence to recommended treatment guidelines and the use of severity assessment tools in the decision making process. We have chosen to use the SMART-COP tool as it was well validated in the Australian Community Acquired Pneumonia Study (ACAPS)7 and more recently noted to have worked well for patients in the Northern Territory8. Antimicrobial recommendations have been formulated based on the findings from ACAPS9, the Therapeutic Guidelines10 and consideration of the local antibiogram of common CAP pathogens.
A baseline retrospective audit of antimicrobial use in Community Acquired Pneumonia (CAP) conducted in the winter of 2011 revealed high rates of inappropriate prescribing that was not concordant with established guidelines. It was proposed to improve the management of CAP with the implementation of a clinical pathway, designed to pull together best practice guidelines for the management of pneumonia across all disciplines involved in the care of these patients.

Within the CAP Pathway, there are promptings for best practices when it comes to VTE prophylaxis, intravenous cannula management and care, pressure area care and infection control prompts regarding hand hygiene and cough etiquette. The focus of the pathway did not just end with the patient journey in hospital. It included ongoing follow up with the general practitioner through a prompt to complete a discharge summary, pharmacy input to ensure any changes to medication is well documented in a Discharge Medication Record and ongoing follow up tests and appointments are arranged.
In striving to provide patient centred, holistic multi-disciplinary care, the CAP Pathway has incorporated elements of preventative care that can affect outcome in patients who are admitted with pneumonia, namely smoking cessation and vaccination. As CAP mainly affects the elderly, the need for a nutritional assessment and physiotherapy referral guidelines are contained within the Pathway to assist clinicians in initiating the appropriate referral when required.
The CAP pathway was implemented in June 2013 with the strong support of hospital administration and an extensive marketing and education campaign, commencing four weeks prior to the start date. Awareness was raised using memes as screen savers on the hospital computers in addition to the face to face education session.
Utilisation of a severity assessment tool improved with the implementation of the CAP Pathway.
There was improved compliance with Prescribing Guildelines in all areas audited – Emergency Department, in-hospital prescribing and on discharge from hospital. The decrease in the prescribing of restricted antibiotics was seen both in ED as well as in-hospital.
ConclusionOur success stems from having: • Clearvisionandagenda • Consistencyofapproach • Multi-disciplinaryinputandownership(Respiratory,Emergency,Generalphysiciansand Intensivists) • Accountabilitythroughfeedbackofdatacollected • SeniorExecutiveandDirectorsupport • Adequateresourcing • EmpoweringthroughtrainingThe optimisation of care of patients with Comminuty Acquired Pneumonia has been a worthwhile Antimicrobial Stewardship intervention for our hospital.
