Multi morbidity - the notion of tacit knowledge - Magdalena Skrybant and Celia Taylor
Mobilising tacit knowledge to
improve care for older patients
Richard Lilford and Gill Combes
65% of 65-84 year olds and 81.5% of 85+ year olds have multiple long-
Multi-morbid patients have higher mortality than expected from
summing the effects of individual diseases. (2)
Good quality care for multi-morbid patients requires coordinated
Care is often sub-optimal:
- Patients report: repeated assessments and clinical tests; fragmented
care; conflicting advice; polypharmacy; and difficulties navigating
- Many patients require multiple individuals to contribute to their care:
hospital specialists, GPs, nurse practitioners, pharmacists, social
workers and voluntary service workers.
- Professionals often work in silos or experience organisational barriers to
multidisciplinary team working.
Limited evidence base for treating multi-morbid patients (3)
Optimal treatment for patients with multiple conditions resists
codification in guidelines.
Requires professionals to identify, elicit, integrate and communicate
many types of knowledge – concept of the ‘bricoleur’. (4)
These types of knowledge can be defined as tacit knowledge (5) or
sticky (6) knowledge.
Tacit knowledge can be surfaced and improved by structured group
education which mirrors the delivery of care.

Developing an intervention
Intervention could be a combination of:
- team-based learning (hospital specialists, GPs, nurse specialists,
pharmacists, social workers)
- interactive, using scenarios/role play/simulation based on real patient
- 3-4 half-day sessions.
2) Team and organisational development
- on-going support for implementing changes to care
- facilitated team meetings every 4-6 weeks for 6 months
- could include peer observation and feedback.
Programme Development Grant
1. Intervention development
- curriculum development
- case studies and scenarios
- team and organisational element.
2. Pre-implementation evaluation
- feasibility of implementation.
1. Development of outcome measures
- patient experience of care
- simulated quality of care
2. Pre-implementation piloting
3. Evaluation with teams from 6-8 GP practices
- 1 year intervention
- 12/18 months evaluation
1. What theories are relevant to the acquisition of tacit knowledge?
2. Is the intervention powerful enough to impact on practice?
3. Is the intervention likely to be able to be implemented, given the
constraints on the NHS?
4. Are there alternatives to the team and organisational development
part of the intervention?
5. What observations might we use to test out if we are on the right
track (in the Programme Development Grant phase)?
6. What might be suitable designs for the final study?
7. What sources of evidence should we seek to collect for which end-
