The NYC Health Department tracks and monitors cases of severe maternal morbidity (SMM) — defined as life-threatening complications during or after childbirth — throughout the city. Our surveillance is based on matching birth certificate data to hospital discharge records from the New York Statewide Planning and Research Cooperative System for all NYC hospital deliveries.
