The U.S. has the worst maternal mortality in the developed world. Hospital-level severe maternal morbidity data exists. Nobody combines it into a live signal a pregnant patient can read.
What it is
Maternal Mortality Early Warning combines CMS severe maternal morbidity (SMM) data, state Maternal Mortality Review Committee findings, Joint Commission perinatal care measures, and CDC PRAMS data into a hospital-level signal published continuously. For every delivery hospital in the United States, surface SMM rate, trajectory, comparison against the state median, and — where the underlying data permits — racial disparity in outcomes within the same facility.
The free, public surface is the core deliverable: pregnant patients, partners, OBs, and doulas choosing a delivery hospital can see what the outcome data says before the choice is made. State health departments, equity researchers, and journalists get a structured upstream signal that today requires hand assembly across five data sources.
The paid institutional surface serves hospital quality leadership benchmarking against peers, MA and commercial payers managing maternity benefit, and the OB and CNM physician staffing companies underwriting their own malpractice exposure. The public-good case is the gate; the paid layer funds it.
Primary data sources
- CMS Severe Maternal Morbidity data — Hospital-level SMM rates
- State Maternal Mortality Review Committees — Cause-of-death and preventability findings (with multi-year lag)
- Joint Commission Perinatal Care measures — Process measures (early elective delivery, cesarean rates, etc.)
- CDC PRAMS (Pregnancy Risk Assessment Monitoring System) — Maternal behavior and experience data
- HCUP NIS and state inpatient databases — Outcome benchmarking where available
Buyers
- Pregnant patients and OBs choosing delivery hospitals (free)
- State health departments and maternal-equity policy teams (free)
- Hospital quality leadership
- MA and commercial payers underwriting maternity benefit
- OB and CNM staffing companies (malpractice exposure)
Methodology
SMM is reported with sample-size confidence bands. Racial disparity reporting follows AHRQ methodology where state data permits. Methodology is disclosed for every metric.
