Establishing Data Infrastructure for a Home Health and Hospice Data Cooperative

Dr. Prusynski is the co-director of the Advancing Health Services & Policy in Rehabilitation (ASPIRe) Lab and an
assistant professor in the Department of Rehabilitation Medicine, Division of Physical Therapy, at the University
of Washington. She is a board-certified clinical specialist in neurologic physical therapy with clinical experience
across the continuum from critical care to community-based rehabilitation in the U.S. and Haiti. Her research
examines the intersections of health and reimbursement policy, therapy practices, and patient outcomes in
post-acute care, with a focus on skilled nursing facilities and home health.
The Long-Term Care (LTC) Data Cooperative, developed under the IMPACT Collaboratory, integrates
normalized electronic health record (EHR) data from nursing homes to capture clinical details not available in
administrative data sources. No equivalent infrastructure exists for home health and hospice settings. In
partnership with BAYADA Home Health, this project will establish the foundational data infrastructure for a
Home Health and Hospice Data Cooperative through systematic inventories of clinical data available in the
Home Care Home Base (HCHB) EHR system and development of a preliminary common data model extending
the LTC Data Cooperative framework to home health and hospice settings. This award will provide Dr.
Prusynski the necessary training and experience working with BAYADA Home Health and their HCHB EHR
system to (1) Complete a systematic data inventory of HCHB home health and hospice, and (2) Develop a
preliminary common data model for a future Home Health and Hospice Data Cooperative that will engage
additional providers and EHR vendors to extend the LTC Data Cooperative framework to these settings. This
project will establish the foundational data infrastructure for a future Home Health and Hospice Data
Cooperative. The training and infrastructure developed through this award will strengthen Dr. Prusynski’s
understanding of EHR data architecture, common data model development, and the governance structures,
enabling multi-site research across nursing homes. These competencies support future efforts to bridge
home health and hospice industry partners with the IMPACT Collaboratory to facilitate pragmatic trials across
the post-acute continuum.
