AISP Network: King County Health & Human Services Integrated Data Hub

King County, Washington, home to Seattle and several other large cities and rural areas, has created an integrated data hub for health and human services that supports cross-departmental client-level reporting and analysis. Since 2017, the team has developed a robust identity matching and mapping process, using Informatica tools, for three core health and homelessness data resources. As of 2021, the King County Departments of Community and Human Services, Public Health, and Information Technology have successfully and routinely linked across Medicaid, Behavioral Health, the Homeless Management Information System, Health Care for the Homeless network data, and local jail bookings. These client-level data resources will continue to be used for program planning and evaluation, population health surveillance, internal quality improvement, and connecting clients to care appropriate to their needs.
