In its 2012 report on the current and future states of public health finance, the Institute of Medicine noted, with concern, the relative lack of capacity for practitioners and researchers alike to make comparisons between health department expenditures across the country. This is due in part to different accounting systems, service portfolios, and state- or agency-specific reporting requirements. The Institute of Medicine called for a uniform chart of accounts, perhaps building on existing efforts such as the Public Health Uniform National Data Systems (PHUND$). Shortly thereafter, a group was convened to work with public health practitioners and researchers to develop a uniform chart of accounts crosswalk. A year-long process was undertaken to create the crosswalk. This commentary discusses that process, challenges encountered along the way and provides a draft crosswalk in line with the Foundational Public Health Services model that, if used by health departments, could allow for meaningful comparisons between agencies.
