Medico-legal cases associated with older physicians' cognitive ability to practice medicine

Dementia increases as individuals age. Aging physicians represent a growing population. Studies have demonstrated there are physicians with cognitive impairments practicing medicine. The medico-legal consequences of physicians with cognitive impairments have not been investigated.

The Canadian Medical Protective Association (CMPA) is a national medical association with 108,000 members who advise and assist doctors with medico-legal matters. They maintain a national repository of legal actions and complaints to regulatory bodies and hospitals. We looked at civil-legal and regulatory college cases closed over a 10-year period associated with physicians aged ≥55. A word search of the cases was conducted using "Dementia, Alzheimer, Cognitive impairment, Cognitive decline, Memory loss, Memory issues, Fit for/to practice."

The CMPA closed 67,566 cases between 2012 and 2021 and 16% (10,599) involved members ≥55. A mixed methodology approach identified 65 cases associated with physician's cognitive ability to practice medicine. Of these 65 cases, the average age of physician was 71.3 (56.1-88.5). The proportion of cases where concern was associated with a physician's cognitive ability to practice medicine increased, from 0.2% of cases in 55-60-year-olds, to 7.7% in physicians over 80.

As physicians age, concerns about cognitive impairment are more likely to contribute to medico-legal matters.
