Exploring diagnostic strategies for memory complaints in older adults: A retrospective general practice database...

For older people who worry about their memory, their general practitioner (GP) is often the first healthcare professional they turn to. This study aims to increase knowledge of GPs' daily practice on diagnostic strategies for patients who present themselves with memory complaints and/or worries about dementia for the first time in general practice and to explore associations of patients' characteristics with these strategies.

Retrospective observational study using electronic patient records from patients presenting with memory complaints between 2012 and 2019. The patient records are derived from a Dutch primary care registration network. The decision on diagnostic strategy was extracted and categorized as (1) wait and see, (2) diagnostic testing in primary care, or (3) referral. Patient characteristics (gender, age, general practice, level of comorbidities, chronic polypharmacy, and the number of consultations on memory complaints), fear of developing dementia, and information on why the first consultation on memory complaints was scheduled were extracted.

A total of 228 patients were included. Most patients were cared for within primary care, either for further primary care diagnostics (56.1%) or because a wait-and-see strategy was pursued (14.9%). One-third (28.9%) of patients were referred. Differences between diagnostic strategies in patient characteristics, fear of developing dementia, or reason for first consultation between these diagnostic strategies were not found, nor were these variables predictive of referral.

Most Dutch patients with memory complaints and/or worries about dementia who seek help from their GP for the first time are cared for in the primary care setting for the following 6 months. The lack of association between included patient characteristics and diagnostic strategies highlights the complexity of the decision-making process on diagnostic testing for dementia in general practice.
