PURPOSE: We assessed the feasibility and acceptability of implementing a digital cognitive assessment (DCA) for Alzheimer disease and related dementias (ADRD) screening into primary care. We also assessed the prevalence of positive screens and measured diagnostic and care outcomes after a positive DCA result.
METHODS: We conducted a single-arm pragmatic clinical demonstration project in 7 diverse primary care clinics to test implementation of the Linus Health Core Cognitive Evaluation and Digital Clock and Recall DCAs (Linus Health, Inc). Eligible patients were aged ≥65 years. Patients were ineligible if unable to see or hear, not English or Spanish speaking, or if they had a DCA in the past 12 months with an unimpaired or impaired result.
RESULTS: There were 16,708 eligible encounters during the 12-month study period (June 2022-May 2023). A total of 1,808 DCAs (10.8%) were completed by 1,722 unique patients; 3,727 (22.3%) declined, and at 9,232 encounters (55.3%) the physicians declined to have the patient complete the DCA or the encounter was deemed out of scope. Among those who completed DCAs, results for 762 (44.3%) were categorized as unimpaired, 628 (36.5%) borderline, 236 (13.7%) impaired, and 96 (5.6%) inconclusive. Among the 236 patients who were categorized as impaired, 2.1% received a new diagnosis of ADRD, and 5.1% received a new diagnosis of mild cognitive impairment within 90 days after the DCA.
CONCLUSIONS: One-half of all patients scored impaired or borderline for cognitive impairment. Digital cognitive assessments can be implemented in primary care, have utility for early detection, and could represent the first step in identification of patients who could benefit from ADRD disease-modifying therapeutics, care management, or other interventions to improve patient and family caregiver outcomes.
