Guideline recommendations on the role of the general practitioner in the diagnosis of dementia: a protocol for a scoping review of clinical practice guidelines

Introduction A timely diagnosis of dementia offers the opportunity of earlier intervention and activation of coordinated care plans. General Practitioners (GPs) play a key role in dementia diagnosis, from symptom recognition to clinical assessment, investigation, diagnosis and onward referral for confirmation of the diagnosis and subtyping. Dementia clinical practice guidelines (CPGs) offer clinicians guidance on dementia care but often do not specifically address the role of the GP in the diagnostic process. This protocol outlines a scoping review to identify evidence-based dementia clinical practice guidelines and map the recommended role of GPs in the diagnosis of dementia. Method The scoping review will be conducted using the Arksey and O'Malley framework, and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews (PRISMA-ScR) will be used to guide the reporting. We will search five electronic databases (PubMed, CINAHL, Embase, PsycINFO, Cochrane Library) for dementia CPGs published since 2019. CPGs are often not published in peer-reviewed journals; therefore, a parallel search of relevant grey literature will be conducted. We will also search the websites of GP professional organisations and guideline developers. Two reviewers will independently screen all articles based on inclusion criteria, with conflicts resolved by a third reviewer. Conclusion This scoping review will examine up-to-date dementia CPGs to determine recommendations for the role of GPs in the assessment, investigation, diagnosis and onward referral of patients with suspected dementia to secondary care.
