The shortage of geriatric specialists in the US may require that primary care physicians (PCPs) receive more education on diagnosing and managing dementia since the number of older Americans with dementia will increase from about five million in 2010 to up to 14 million in 2050. Thus, we administered a brief, anonymous questionnaire to determine PCPs' diagnostic, referral, and management practices to a convenience sample of 142 PCPs in Arkansas. We reworded a Scottish survey to conform to terminology used in the US and added items on referral practices. The PCPs who reported difficulty establishing the diagnosis of dementia had more difficulty telling the diagnosis (O.R = 3.59, p < 0.004). The PCPs were less likely (p < 0.001) to tell the patient if they suspected dementia (73%) than if they were sure the patient had dementia (88%). In both cases, they were more likely to tell the family (92% & 100%, respectively), although this difference was not statistically significant. The PCPs discussed disease progression and driving risks with patients and families, but few referred them to social workers or community agencies. Findings support training PCPs in the diagnosis and management of persons with dementia and providing tools to improve care.
