This brief details the steps to be followed in obtaining and compiling data on the core (and optional) measures of public health service delivery for the MPROVE study. MPROVE data will need to be obtained from several different sources. Data for some measures already exist in administrative records, surveillance systems, or other sources maintained by the local and state public health agencies that participate in your PBRN. For other measures, it may be necessary to obtain data from other agencies that collaborate with the public health agencies in your PBRN. In still other cases, it may be necessary to undertake primary data collection by fielding a brief survey with local public health professionals included in your PBRN.
