Benefits of public involvement nhs
Benefits of public involvement (NHS)

  • better outcomes of treatment and care

  • a more satisfying experience for patients of using health services

  • sharing responsibilities for healthcare with the public

  • more appropriate use of health services

To give patient participation a regular place in guidelines, in order to achieve a more demand-based care

by incorporating aspects of patients' perception and experience and their information needs


  • Definition and scope

  • Construction of concept-filters

  • Validation database

  • Adaptation of concept-filters

Definition and scope sign
Definition and scope (SIGN)

  • experiences (condition, diagnosis, treatments, follow-up care and QoL)

  • (information) needs and preferences

  • participation in decision-making

  • overall satisfaction with care received

Construction of concept filters for medline via ovid and via pubmed
Construction of concept-filters (for Medline via OVID and via PubMed)

Terms derived from:

- filter patient issues SIGN

- Greenhalgh, T. User involvement in health care (Wiley, 2010)

- analysis of known articles

Validation database
Validation database

  • guidelines SIGN

  • Longtin Y et al. Patient participation: current knowledge and applicability to patient safety. Mayo Clin Proc. 2010 85(1):53-62

  • guideline diabetes self-management education

    Result: 176 references

Adaptation of concept filters
Adaptation of concept-filters

  • Computerized analysis of MESH-terms of articles in validation database with open source MESH-analysing apps

  • Manual analysis of missed articles:

    • 23 (concept OVID-new filter),

    • 6 (concept PubMed-new filter),

    • 1 (OVID-SIGN filter)
