Intergenerational differences in workloads among primary care physicians: a ten-year, population-based study.

Analyses of population-based services and surveys in Canada from the early 1990s and early 2000s indicate that younger and middle-aged family physicians carried smaller workloads in 2003 than their same-age peers did ten years earlier and that older family physicians carried larger workloads in 2003 than their same-age peers did ten years earlier. Yet family physicians in all age groups worked similar numbers of hours in 2003. Intergenerational effects are similar for male and female physicians, although feminization of the workforce will affect supply, as a result of the falling service volumes delivered by women.
