The Sentinel Distributed Database (SDD) is comprised of quality-checked data held by 18 partner institutions. Data at these partner institutions are generated from patient interactions with the United States healthcare system through their insurers and providers. For example, fictitious patient Bob (shown below) is a male who is enrolled in a health plan and experiences several medical encounters between 2011 and 2014.

Bob’s diagnoses, procedures, and prescription information from his medical encounters appear in Sentinel data along with information from billions of medical encounters from other patients across the U.S. Data are aggregated to preserve the privacy of every individual member contributing to the SDD.
