Unwarranted variation

Why do we need theory?
Check whether theory is logical
Check against empirical observations

What is a Quality Improvement
Collaborative?A QIC is an organised, multifaceted approach to quality
improvement involving five essential features:
• (1) specified topic (problem)
• (2) clinical experts and experts in quality improvement
provide ideas and support for improvement
• (3) multi-professional teams from multiple sites
participate
• (4) model for improvement (measurement, change,
feedback)
• (5) collaborative process involves series of structured
activities.Hulscher M, Schouten L. Grol R Collaboratives. London Heslth Foundation, 2009.

IHI: Model for improvement

Are collaboratives effective?
220 QIC studies: 64 met design
standards for inclusion
Improvement in 1 or more outcomes in
83% including 1 ambulance study
(ASCQI)
Straightforward aspect of care, strong
evidence, clear gap, accepted guideline.

• Listening, empathy, taking the problem seriously
• Health beliefs: concerns about sleep tablets vs.
need for help
• Previous self-help: what they have tried already:
OTC, complementary
• Careful assessment
• Problem focused therapy: including CBT-i
What patients needed

a focus group study. BJGP 2010; 60: 329 -333.

• Don’t assume that patients would always want or
need a prescription
• Many patients had tried non-drug treatments but not
adequately or consistently
• Patients often open to alternatives

How did change occur?
• Engagement of practice staff
• Willingness to innovate and initiate change
• Better understanding of patient expectations
and staff preconceptions
• Commitment to address educational and
learning needs for patients and practitioners
• Overcoming barriers to implementing new tools
and techniques
• Response to feedback on new tools and
techniques
• Approach tailored to practice

Key explanations
• 7 services had improvements in both AMI and
stroke: 5 used checklists; 4 used feedback - 3
used individual feedback (1 with group feedback
also) and 1 used group feedback alone.
• 5 had an improvement in AMI or stroke but not
both: 2 used checklists (1 used it late), 2 used
group feedback.

Problem: scaling up PINCER
• Prescribing errors
• 1 in 550 items containing a severe error
• Cause of around 1 in 25 hospital admissions
• Antiplatelet agents, diuretics, NSAIDs and
anticoagulants - over 50% of preventable drug
related admissions.

PINCER• PINCER: pharmacist-led information technology
intervention for reducing clinically important errors in
medication management in general practices.
• PINCER trial:
– 29% reduction in the proportion of patients with at least one
prescribing error;
– 44% reduction in the proportion of patients with at least one
medication monitoring error;
– Economic analysis showed PINCER was cost effective.
• Scaling Up PINCER
– Aim to spread PINCER to at least 150 general
practices in the East Midlands region

Indicator A: Prescription of an oral NSAID, without co-prescription of an
ulcer healing drug, to a patient aged ≥65 years
![Page 41: Quality improvement collaboratives: theory, design and effects...• (2) clinical experts and experts in quality improvement provide ideas and support for improvement • (3) multi-professional](https://reader033.vdocument.in/reader033/viewer/2022050114/5f4b8e4a553f6754440bd69d/html5/thumbnails/41.jpg)
Common features
• Logic model, theory of change
• Complex (pragmatic) contexts:
intervention, setting, participants
• Learning: shared learning
• Intervention: can/will undergo
transformation
• Change: variation in outcomes, un
anticipated effects
![Page 42: Quality improvement collaboratives: theory, design and effects...• (2) clinical experts and experts in quality improvement provide ideas and support for improvement • (3) multi-professional](https://reader033.vdocument.in/reader033/viewer/2022050114/5f4b8e4a553f6754440bd69d/html5/thumbnails/42.jpg)
Different types of collaborative
1. Intervention
development
Generating new or adapting
interventions
Small scale, intervention
design +/- outcome
measurement
2. Improving process
reliability
Increasing reliable
implementation of evidence
based processes
Medium to large scale
implementation and
outcome measurement
3. Scaling up
innovations
Evidence based intervention Large scale,
implementation and
outcome measurement

Summary
• QIC aims vary: more than improving care
• Interventions may change during QICs:
intended vs. unintended: this should be
described
• Effects: vary by organisational unit and by
indicator
• Should systematic reviews of their
effectiveness/effects take these into
account?
