5-Cog Paradigm to Improve Detection of Cognitive Impairment in Primary Care Pragmatic Clinical Trial

What this Trial Is About

Cognitive impairment related to dementia is often missed in primary care, especially among older adults from minority and socio-economically disadvantaged populations. Researchers are evaluating the 5-Cog brief cognitive assessment, a quick, simple, and standardized tool that takes less than 5 minutes and addresses cultural and logistical barriers. This pragmatic cluster-randomized trial aims to test whether the 5-Cog paradigm improves detection of new cases of cognitive impairment and dementia care in older adults with cognitive concerns. The study involves 22 primary care clinics in Bronx and Indiana, enrolling about 6,600 patients aged 65 and older who report cognitive concerns. Participants receive either the 5-Cog battery combined with a clinical decision-making tool or enhanced usual care, which includes cognitive concern screening. The 5-Cog battery includes tests like Picture Memory Impairment Screen, Motoric Cognitive Risk Syndrome diagnosis, and Symbol Match. Primary care physicians receive results and decision support but use their clinical judgment in care decisions. Participants undergo cognitive concern screening before their appointments. Researchers will review new cognitive impairment diagnoses and improvements in dementia care within 90 days after the primary care visit using electronic medical records. Additional evaluations include tests for reversible causes, medication changes, specialist referrals, and social support. The study also examines the 5-Cog paradigms implementation and cost-effectiveness, focusing on populations facing health disparities. Total participation duration varies by patient and clinic schedule.
