AlertWatch:OB vs PeriGen
The obstetric early warning shortlist, and with only two credible occupants this is a real decision rather than a manufactured one. PeriGen has the deeper regulatory history, with multiple cleared components for automated fetal heart rate interpretation and labor progress, and the only independent validation in this category performed by experts at a federal research institute rather than by the vendor or a customer. AlertWatch:OB started from a different premise: alarm fatigue was the founding design problem, and the filtering layer that follows from that is the thing to test, because a labor and delivery unit is already saturated with alarms and a system that adds to them will be ignored. Neither publishes any subgroup performance analysis, which in United States obstetrics, where maternal outcomes differ sharply by race, is the most important omission on either record.
- Alarm fatigue was the founding design problem rather than a later fix, with a proprietary filtering layer over the alert stream, which is the correct starting point in a unit where continuous monitoring already produces more alarms than anyone can act on.
- A repeated clearance history across three products covering the operating room, acute care and obstetrics, so the regulatory approach is established rather than product specific.
- It ingests hundreds of data elements across physiological monitors, the record system and laboratory feeds rather than reading one source, which is what a maternal early warning score needs.
- Its algorithms were validated by experts at a federal research institute rather than by the company or its customers, which is the only independent validation of that kind in this category.
- The deepest and longest regulatory history here, with multiple cleared components across years covering automated fetal heart rate interpretation and labor progress.
- It draws continuously from the hospital's existing fetal monitoring infrastructure rather than requiring it to be replaced, and its named deployments span an unusually wide range of institution types.

Neither vendor publishes subgroup performance, calibration or fairness analysis, and obstetrics is the clinical domain where that gap costs most: maternal mortality and severe morbidity in the United States differ sharply by race, and an early warning system that performs unevenly across those groups would widen rather than narrow the gap it is sold to close.
Neither publishes a privacy policy, retention period, training use disclosure, security attestation, trust centre or business associate terms, and neither publishes pricing. AlertWatch's named deployments are dated enough that a buyer should ask for current reference sites rather than relying on the published list.
