the problem
Clinical truth is buried across a dozen systems.
Readmission rates, occupancy, case mix and payroll live in different schemas with cryptic column names. Analysts spend days reconciling definitions, and AI on top of undocumented PHI is a compliance risk waiting to happen.
use cases
Questions Healthcare teams ask Sema.
30-day readmissions

Staffing & NHPPD
Nursing hours per patient day vs. acuity, flagged the moment a facility drifts below target.
Payer mix & PMI
Medicare/Medicaid/private split and per-member income trends, defined once and consistent everywhere.
