Patient Centered Data Home: national overlay repatriates data to patients’ home networks

David Kendrick, senior subject matter expert at Civitas/Networks for Health, described the Patient Centered Data Home (PCDH) as an operational overlay that connects state and regional health information exchanges so clinical data can be repatriated to the network where a patient lives. He said PCDH currently connects about 40 networks and supports roughly 200 million lives of interoperability.

“It supports about 200,000,000 lives worth of data interoperability,” Kendrick said, explaining that PCDH uses a national data exchange agreement, regional hubs and a ZIP‑code routing protocol that forwards ADT messages to the network responsible for the patient’s home. He said participating networks vet users locally, enforce state laws and consent, and that the model has operated for about a decade with no known systemic breaches attributable to the overlay. Kendrick highlighted repatriation as the main benefit—bringing externally generated clinical events back to the patient’s home network so local care teams can integrate those events into ongoing care plans.
