The Colorado Department of Public Health and Environment (CDPHE) is expanding its Colorado Health Systems Directory (CHSD) to include public health workers, a critical step made possible by PHIG funding. This database uses a standardized program-level taxonomy to categorize public health workers across agencies and programs, strengthening workforce recruitment, retention, and professional development. The initiative has already collected key data from partners, with plans to import its first data file into the CHSD by the end of 2024. Collaboration with local and state partners, including the Colorado School of Public Health, has been key to the project’s success. CDPHE plans to refine and scale the taxonomy to ensure a long-term impact on workforce development and public health outcomes.
