Excerpt from authors] Traditional approaches to health human resources planning emphasize the effects of demographic change on the needs for health human resources. Planning requirements are largely based on the size and demographic mix of the population applied to simple population-provider or population-utilization ratios. We develop an extended analytical framework based on the production of health-care services and the multiple determinants of health human resource requirements. the requirements for human resources are shown to depend on four separate elements: demography, epidemiology, standards of care, and provider productivity. The application of the framework is illustrated using hypothetical scenarios for the population of the combined provinces of Atlantic Canada.
