The attitude of physicians toward retirement was studied using a questionnaire sent to physicians aged 65 and older. The information obtained was supplemented by organizing a study group of interested doctors. Of the 58 respondents whose average age was 71, 54 were still in practice and 65% had no plans for retirement. There was a strong urge to maintain the status quo. The group discussion centered around the loss of control over one's declining practice and the fear of diminishing competence with advancing age. The dedicated lifetime pursuit of a medical practice makes retirement extremely difficult for today's older physician. This study supports surveys on the working life span, longevity and mortality of North American physicians.
