Recruiting at 2 sites in United States. Open to participants aged 65 Years and older. Per ClinicalTrials.gov, last updated 2026-04-17.

Cognitive impairment related to dementia is frequently under-diagnosed in primary care settings. This problem is more prevalent in health disparities populations. The investigators developed the 5-Cog brief cognitive assessment that is simple to use, standardized, takes \<5 minutes, does not require informants, and accounts for major technical, cultural, and logistical barriers of current assessments. The investigators propose a hybrid Type 1 effectiveness-implementation design in real-world settings to adapt and test the effectiveness of the 5-Cog paradigm to increase detection of cognitive impairment care in older adults presenting with cognitive concerns.
The study aim is to evaluate, using a pragmatic cluster-randomized trial design, the effectiveness of the 5-Cog paradigm to increase 'incident cognitive impairment' detection (new MCI and dementia diagnoses) relative to enhanced usual care in 6,600 older patients presenting with cognitive concerns in 22 primary care clinics in Bronx and Indiana. As diagnosis without action will not improve patient care, 'improved dementia care' will be examined as a secondary outcome. Results will also be examined in NIH designated health disparity populations including underserved minority and socio-economically challenged populations.
Cognitive impairment related to dementia is frequently under-diagnosed in primary care settings despite the increasing rates of patient cognitive complaints and the availability of numerous cognitive assessment tools. Missed detection delays treatment of reversible conditions as well as provision of support services and critical planning. This problem is more prevalent among older African-Americans and Hispanics than older whites, and more common in rural than urban populations.
The investigators developed the 5-Cog brief cognitive assessment that is simple to use, standardized, takes \<5 minutes, does not require informants, and accounts for major technical, cultural, and logistical barriers of current assessments. The investigators are conducting a simple randomized clinical trial to examine the clinical efficacy of the 5-Cog paradigm (5-Cog brief cognitive assessment paired with a clinical decision-making tool) to improve dementia care in 1,200 predominantly minority sample of older adults with cognitive concerns presenting to a primary care clinic in the Bronx. Interim analysis revealed that the 5-Cog paradigm resulted in an over 8-fold increase in new cognitive impairment diagnoses and over 3-fold increase in improved dementia care actions by primary care physicians compared to an active control arm. Following up on these very promising results, the investigators propose a hybrid Type 1 effectiveness-implementation design in real-world settings to adapt and test the effectiveness of the 5-Cog paradigm to increase detection of cognitive impairment care in older adults presenting with cognitive concerns.
The aim of the pragmatic cluster-randomized trial is to test the clinical effectiveness of the 5-Cog paradigm in increasing cognitive impairment detection and improving dementia care - ascertained via electronic medical record. Randomization will be at the clinic level, and select 22 primary care practices; 6 in Bronx and 18 in urban and rural Indiana. 300 participants per practice will be enrolled for a total of 6,600 older patients with cognitive concerns. Results will also be examined in NIH designated health disparity populations including underserved minority and socio-economically challenged populations.
Outcomes are new cognitive impairment diagnoses (primary) and improved dementia care (secondary) in the 90-day period following presentation of cognitive concern to the primary care physician.
Implementation issues and cost-effectiveness of the 5-Cog paradigm will also be examined.
This proposed study focuses on scalable approaches to address the unmet need of early detection of incident cognitive impairment, including in populations that experience health disparities.

Exclusion Criteria:
A cognitive concern screening will be conducted with patients aged 65 and older prior to their appointment with their primary care physician. If cognitive concerns are endorsed the 5-Cog battery will be conducted. The simple, \<5-minute cognitive assessment will reliably identify older persons with cognitive impairment in primary care settings, and flag them for further evaluation. Depending on whether the 5-Cog results are normal or abnormal on any one of the 3 tests, appropriate clinical decision support tools are provided to the primary care physicians in electronic medical record. The primary care physicians are not instructed to follow 5-Cog suggestions verbatim but use their clinical judgment.
Other: 5-Cog Paradigm (5-Cog battery coupled with clinical decision tool)
Educational sessions for primary care physicians and clinic staff regarding cognitive detection and medical billing will be conducted. A cognitive concern screening will be conducted with patients aged 65 and older prior to their appointment with their primary care physician. The results will be provided to primary care physicians.
Other: Enhanced usual care
A cognitive concern screening will be conducted with patients aged 65 and older prior to their appointment with their primary care physician. If cognitive concerns are endorsed the 5-Cog battery will be conducted. The 5-Cog battery includes the Picture Memory Impairment Screen, Motoric Cognitive Risk Syndrome diagnosis, and Symbol Match. The simple, \<5-minute cognitive assessment will reliably identify older persons with cognitive impairment in primary care settings, and flag them for further evaluation.
A cognitive concern screening will be conducted with patients aged 65 and older prior to their appointment with their primary care physician. The results will be provided to primary care physicians.
New cognitive impairment diagnoses in the 90-day period following presentation of cognitive concern to the primary care physician (PCP).
The clinical effectiveness of the 5-Cog paradigm on new cognitive impairment detection will be examined by comparing the proportion of 'new Mild Cognitive Impairment (MCI) and dementia diagnoses' over 90-days in the 5-cog paradigm and the enhanced usual care group using generalized linear mixed effects models. For patients with a previous diagnosis of MCI in the electronic medical record, only a new diagnosis of dementia will be considered as an incident outcome.
Time frame: Up to 90 days
Improved dementia care in the 90-day period following presentation of cognitive concern to the primary care provider (PCP).
The clinical effectiveness of the 5-Cog paradigm on improved dementia care will be examined by comparing the proportion of documentation of improved dementia care in the 5-cog paradigm and the enhanced usual care group using generalized linear mixed effects models. Improved dementia care is defined as any of the following: 1. Tests ordered for reversible causes of cognitive impairment as per published guidelines. 2. New cognitive enhancing medication prescriptions or deprescribing anti-cholinergic. 3. Referral for cognitive/dementia evaluation by specialists (Neurology, Geriatrics, Psychiatry). 4. Referral to social worker or community-based organizations.
Time frame: Up to 90 days
Plan to share: Yes — De-identified individual participant data for all primary and secondary outcome measures will be made available with appropriate ethics committee and data sharing agreements in place.
