Product methodology
Maternal Mortality Early Warning
Source contract, normalization path, entity-graph join, refresh posture, and publication limits for this Branmoor product.
Status
Pending. This product is pending. The methodology page is published first so the source contract and join path are visible before Branmoor represents the product as live.
Distribution Scope
Nationwide where data supports it; TN MMRC/perinatal layer; Nashville Maternal & Perinatal Watch
Product Question
Flags maternal/perinatal risk signals by facility and region.
Primary 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
Entity-Graph Join
`ccn`, birthing-friendly facility flag, county/tract, diagnosis/procedure groups.
Publication Rule
Branmoor does not treat raw public records as the product. A surface is publishable only when the source record is dated, normalized, source-linked, and joined to the relevant Branmoor entity identifiers with enough confidence to state the limits of the result.
Current Methodology Note
SMM is reported with sample-size confidence bands. Racial disparity reporting follows AHRQ methodology where state data permits. Methodology is disclosed for every metric.
Limits
Coverage follows the underlying source. Missing state portals, gated APIs, PDF-only filings, suppressed fields, lagged agency refreshes, and entity-name ambiguity can all limit product completeness. Pending products are not marketed as live until those limits are documented on the product surface.
