From measuring to improving public health practice.

Efforts to measure public health practice have taken on various forms and focused on different aspects of the system of public health practice over the past century. Before 1990, measurement was primarily based on a series of self-assessment instruments initiated under the auspices of the Committee on Administrative Practice of the American Public Health Association. These instruments emphasized measurement of immediate results of local public health services although they also provided information on local resources and capacity to perform. Following the Institute of Medicine's report in 1988, efforts began to focus on performance related to public health's core functions. These more recent assessments suggest that the system of public health practice must be improved to achieve the targets of effectiveness established for the year 2000. Ultimately, a comprehensive national surveillance system for public health practice will need to both measure and examine the relationships among inputs (resources, capacity, etc), core function-related processes, outputs (services) as well as outcomes.
