Learn how OHS manages patient discharge data
The Office of Health Strategy (OHS) supports legislation, policies, and research that improve health and healthcare delivery in Connecticut. We compile healthcare information from providers across the state to support that mission.
Patient discharge data is among the information OHS collects. OHS collects four main types of discharge data:
- Inpatient discharges from acute care hospitals
- Outpatient surgery discharges from hospitals
- Outpatient surgery discharges from ambulatory surgery centers (ASC)
- Emergency room discharges
