Cognitive Assessment of Elderly Primary Care Patients

Study Overview
=================
Brief Summary
-----------------
Most primary care physicians do not screen older patients for cognitive impairment. Identification of cognitive impairment may result in earlier referral for diagnostic work-up and earlier treatment and better patient outcomes. The purpose of this study is to determine whether physicians who receive the results of a cognitive screen use this information in treatment plans and whether this results in better cognitive outcomes for the older patients.

Detailed Description
-----------------
Current trends in healthcare suggest that in the coming decade most older patients will obtain services solely through the general practice/family practice sector of healthcare. Effective and optimal management of older patients with multiple complex medical conditions and compromised cognitive functioning will be a challenge for the primary care physician (PCP). Early identification of older patients with cognitive deficits should allow early referral for diagnostic work-up and earlier treatment and better patient outcomes. The goal of this study is to investigate the utility of providing cognitive testing in the PCP office. PCPs will be randomized to either Treatment As Usual (TAU) or Cognitive Report (CR). The study hypotheses are (1) patients of physicians in the CR group will have improved clinical outcomes i.e. cognitively impaired patients in the CR group will have a slower rate of progression of cognitive deficits over two years than cognitively impaired patients in the TAU group; (2) PCPs in the CR group will order dementia screening tests, refer to specialists and prescribe anticholinesterase inhibitors more frequently than PCPs in the TAU group.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cognitive Report<br>Primary care physicians in the Cognitive Report group receive the results of their patients cognitive testing together with clinical diagnosis (Normal, Mild Cognitive Impairment, Dementia) and treatment recommendations. | Behavioral: Cognitive Report<br>* Physicians in the Cognitive Report group receive the results of their patients cognitive assessment which includes a clinical diagnosis (Normal, Mild Cognitive Impairment, Dementia) and treatment recommendations<br>|
| Experimental: Treatment As Usual<br>Physicians in the Treatment As Usual Group do not receive the results of their patients cognitive assessment, they do not receive treatment recommendations, nor are they told of the patients diagnosis (Normal, Mild Cognitive Impairment, Dementia) | Behavioral: Treatment As Usual<br>* Physicians in the Treatment As Usual group do not receive the results of their patients cognitive assessments, they are not given treatment recommendations nor are they told of the patients clinical diagnosis (Normal, Mild Cognitive Impairment, Dementia).<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Scores on a comprehensive battery of neuropsychological tests. | Diagnosis is based on performance on a standard neuropsychological test battery that assesses mutliple cognitive domains known to be sensitive to early dementia. | Two years |
