The document describes several clinical systems used at Mount Sinai including Cerner, IDX Flowcast, EPIC, and others. Cerner is the primary EMR and tracks patient demographics and encounters. IDX Flowcast serves a similar role for outpatient clinics. EPIC replaced older systems and captures clinical documentation, orders, and results. Data from these sources are extracted nightly and loaded into the Mount Sinai Data Warehouse to create a centralized repository for analytics and reporting.
