Information needs for GPs on type 2 diabetes in Western countries: a systematic review.

Background: Most people with type 2 diabetes receive treatment in primary care by GPs who are not specialised in diabetes. Thus, it is important to uncover the most essential information needs regarding type 2 diabetes in general practice.

Aim: To identify information needs related to type 2 diabetes for GPs.

Design and setting: Systematic review focused on literature relating to Western countries.

Method: MEDLINE, Embase, PsycInfo and CINAHL were searched from inception to January 2024. Two researchers conducted the selection process, and citation searches were performed to identify any relevant articles missed by the database search. Quality appraisal was conducted with the Mixed Methods Appraisal Tool. Meaning units were coded individually, grouped into categories, and then studies were summarised within the context of these categories using narrative synthesis. An evidence map was created to highlight research gaps.

Results: Thirty-nine included studies revealed eight main categories and 36 subcategories of information needs. Categories were organised into a comprehensive hierarchical model of information needs, suggesting 'Knowledge of guidelines' and 'Reasons for referral' as general information needs alongside more specific needs on 'Medication', 'Management', 'Complications', 'Diagnosis', 'Risk factors', and 'Screening for diabetes'. The evidence map provides readers with the opportunity to explore the characteristics of the included studies in detail.

Conclusion: This systematic review provides GPs, policymakers, and researchers with a hierarchical model of information and educational needs for GPs, and an evidence map showing gaps in the current literature. Information needs about clinical guidelines and reasons for referral to specialised care overlapped with needs for more specific information.
