Objective: The purpose of this study was to better understand obstetric codes requiring rapid response team activation by examining their incidence, indications, team response, and patient outcomes.
Methods: This was a retrospective study in peripartum women who required activation of the following codes during hospitalization between January 2014 and May 2018: "Code 77 (C77)" (obstetric emergency), "Code Blue (CB)" (cardiopulmonary compromise) or "Code Omega (CO)" (massive transfusion). Hospital database and health records were searched to identify and review cases. Data on code characteristics, resuscitative measures, and maternal and neonatal outcomes were collected.
Results: A total of 147 codes were identified during the study period (C77, 110; CO, 25; CB 12), with an overall incidence of 1 per 203 deliveries (C77, 1:271 deliveries, CO, 1:1194 deliveries; CB, 1:2488 deliveries). Common indications for C77 were cord prolapse (33%) and fetal bradycardia (32%), and for CO and CB, postpartum hemorrhage (84%) and cardiac arrest (42%), respectively. Most codes (67%) occurred after hours. The median decision-to-delivery interval was 8 (interquartile range 5-15) minutes after C77. Emergency cesarean delivery was performed for 57% of obstetric emergencies, and general anesthesia was administered in 63% of cesarean deliveries. Maternal and neonatal mortality rates were 0.68% and 7%, respectively. Major maternal morbidity was seen in 33% of cases. Debrief was documented for 4% of codes.
Conclusion: Rapid response team activation was required more commonly in C77 than in CO or CB. Their response time and decision-to-delivery intervals were rapid. Mortality was low; however, one-third of parturients had major morbidities. We suggest closer patient monitoring, immediate availability of resources, and appropriate documentation and debriefing.
