Abstract
Hospital labor and delivery floors frequently operate like intensive care units (ICUs)—with
continuous data feeds pouring into central monitoring stations against a background
of blaring alarms. Yet the majority of obstetric patients are healthy and do not require
ICU-level care. Despite limited organizational recommendations guiding the frequency
of vital sign measurement, continuous pulse oximetry is used widely for laboring patients.
There is also no evidence that morbidity prevention is linked to specific frequencies
of vital sign monitoring in low-risk patients. In fact, studies examining the performance
of maternal early warnings systems based on vital signs suggest that these may not
reliably provide actionable information regarding maternal physiologic status. Furthermore,
it is very possible that intrapartum maternal overmonitoring can impact care negatively
by generating alarm fatigue, causing providers to miss actual abnormal vital signs
that may precede morbidity.
Key Points
-
Labor and delivery units may engage in maternal physiologic overmonitoring.
-
Overmonitoring increases risk for alarm fatigue.
-
Deimplementing low-value care may improve obstetric outcomes.
