Making Healthcare Safer 2:Critical Analysis of the Evidence for
Patient Safety Practices
Paul G. Shekelle, MD, PhD, on behalf of the Patient Safety Practice Team
Patient safety is a big problem
• 44,000 to 80,000 people die in the US each year due to diagnostic errors
• 68,000 people die of decubitus ulcers
• Many thousands more die from other preventable causes, e.g.,
– Teamwork and communication errors
– Failure to receive evidence-based interventions
• Costs of these errors are more than $30 billion (€23 billion)
Making Health Care Safer I
In 2000, the Agency for Healthcare Research and Quality commissioned a systematic review of patient safety practices
The report identified some early evidence-based safety practices:•General clinical topics•Organization, structure, and culture•Systems issues and human factors•Patient role
• Adverse drug event prevention• Infection control• Surgery, anesthesia,
perioperative medicine• Safety practices for
hospitalized or institutionalized elders
This report highlighted the enormous gap between what was known and what needed to
be known
Fast forward 10 years...

MHCS I MHCS II
MHCS II was a 4-year project conducted in 4 stages:•Developing a conceptual framework•Reviewing the evidence•Conducting a technical expert panel•Making recommendations
The conceptual framework comprised 6 factors for evaluating a PSP
• Explicit description of the theory on which the PSP rests
• Description of the PSP, including staff roles
• Measurement of contexts
• Details of implementation
• Assessment of outcomes and unexpected effects
• Assessment of influence of context on effectiveness

The evidence review had 3 key concerns
• Context
• Implementation
• Adoption
Context has at least 4 domains
External factors
Organizational
structural characteristics
Management Tools
Teamwork, leadership,
patient safety culture
• Regulatory requirements
• Payments or
penalties, e.g., Public
reporting• National
campaigns, collaboratives, or sentinel
events
• Size, complexity,
• Location
• Financial Status
• Existing infrastructure
• Training resources
• Internal audit and feedback
Why is context important?

Improving Patient Safety Is Like Gardening
Is this the right soil?
Has the soil been prepared?
Will it get enough sun?
Will it get enough water?

MHCS II sought to understand the role of contextual factors in the implementation and
effectiveness of interventions to improve patient safety
How we conducted the reviews...
We searched for evidence in 2 ways
• We sought and extracted data about context, implementation, and unintended harms
– From studies that evaluated the effectiveness of safety strategies
• We identified implementation studies
– Studies that focused on elements of implementation processes shown or thought to influence the success of the intervention
Topic Refinement
• Began with a list of 158 potential PSPs
– 79 MHCS 1 topics + NQF 2010, Joint Commission, Leapfrog
• Conducted processes to combine and eliminate to reach 97 potential PSPs
– internal team triage
– conference with TEP
In-depth reviews (18) Brief reviews (23)
Review process involved several steps
1. Search for existing systematic reviews
– Assessing their potential relevance, quality
2. If relevant reviews found If no reviews found
3. Update search
or abbreviated searchFull search
We then characterized each strategy by...
• Scope of the underlying problem
• Strength of evidence about effectiveness
• Evidence or potential for harmful consequences
• Rough cost estimate
• Estimate of difficulty of implementation
Some examples...
Chapter 19. Preventing In-Facility Falls
The Problem:
• 1.3-8.9 falls per 1,000 bed-days occur in acute care hospitals
• 30%-50% of in-facility falls are associated with reports of injuries
• In-patient falls have been associated with $13,000 in increased costs and an increase of 6.3 days’ length of stay
What is the Patient Safety Practice?
Most in-facility fall prevention programs aremulticomponent interventions:
• Falls risk assessment
• Post fall review
• Patient education
• Staff education
• Footwear advice
• Scheduled and supervised use of toilet
• Medication review to assess for medications that affect alertness and balance
And many additional intervention components exist
Why should this Patient Safety Practice work?
Falls prevention interventions have no real identifiedconceptual framework, BUT
• Falls are understood to have a multifactorialetiology
• Attention to multiple risk factors is expected to have better outcomes than targeting a single factor
• Falls usually result from a combination of patient-specific risk factors (e.g., age>85, history of falling) and environmental risk factors (e.g., poor lighting)
• Insufficient staff time is often allocated for thorough fall risk assessment
What are the beneficial effects of the Practice?
Evidence from 3 systematic reviews and an updatesearch supported similar conclusions:
• Multi-component in-facility falls prevention programs significant reduce fall rates
• These programs reduce fall rates more effectively than do any single component interventions in acute care settings
And the interventions have not been associated withany actual adverse effects.
How has the Practice been implemented
and in what contexts?
Effective implementation in hospitals and seems toinvolve a number of consistent themes:
• Leadership support
• Engagement of front line clinical staff in intervention design
• Multidisciplinary committees to oversee interventions
• Pilot testing the intervention
• Informational technology systems
• Changing the prevailing attitude about the inevitability of falls
• Education and training of clinical staff
Cited as one of the strongest factors
for success
Chapter 24. Rapid-Response Systems
The Problem:
• Unrecognized deterioration in the clinical status of in-patients can progress to cardio-respiratory arrest,
• These arrests are associated with poor prognosis, YET
• Clear signs and symptoms predicting the arrest are often present
What is the Patient Safety Practice?
Rapid response systems:
• Combine improved recognition of deterioration and a critical care team to respond
• Comprise 4 components
– Criteria for notifying the response team (e.g., vital signs) and a system for activating it
– The response team (medical emergency team)
– Feedback loop to analyze event data for quality improvement
– Administrative component to coordinate staff, resources, equipment, and education
Why should this Patient Safety Practice work?
• Most cardio-respiratory arrests have clear antecedents indicating deterioration
• Yet these indications are not recognized or recognition is delayed
• Even when signs are recognized, a variety of systemic barriers prevent response
THEREFORE
• Improving the recognition process by defining criteria and spreading this knowledge should result in earlier recognition and intervention
What are the beneficial effects of the Practice?
Evidence from 1 high-quality systematic review and an update search showed:
• Among adults, implementation of a RRS was associated with reduction in cardiopulmonary arrest inpatients in general wards
• Among children, implementation of a RRS was associated with reduction of both cardiopulmonary arrest and in-hospital mortality
Effects are small but most studies were not welldesigned and didn’t do long-term assessment.
How has the Practice been implemented
and in what contexts?
• Most studies occurred in academic medical centers
• 5 major themes identified:
– Education on the medical emergency team
– Expertise
– Support of medical and nursing staff
– Nurses’ familiarity with and advocacy for the patient
– Nurses’ workload
• Improved implementation is associated with
– Technology and tools
– Staff and training
– Barriers and facilitators
