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

Viewpoint of our two organisations

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

Methods

• Definition and scope• Construction of concept-filters• Validation database• Adaptation of concept-filters

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)

Terms derived from:

- filter patient issues SIGN

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

- analysis of known articles

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

• 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)
