The public health workforce.

The development of a fully-competent public health workforce as a key component of the nation's public health infrastructure has become the focus of increasing attention. The subject is included in one, and is the major topic of a second, report from the Institute of Medicine published late in 2002. Workforce issues have stimulated the convening of the majority of public health-related associations in a range of collaborations on the subjects of defining, enumerating, credentialing, educating, and studying the workforce. The authors review the major questions confronting the field and introduce key components of current thinking about approaches to improvement.
