Abstract

ObjectiveTo determine if real-time compression feedback using a non-automated hand-held device improves patient outcomes from in-hospital cardiac arrest (IHCA).MethodsWe conducted a prospective, randomized, controlled, parallel study (no crossover) of patients with IHCA in the mixed medical-surgical intensive care units (ICUs) of eight academic hospitals. Patients received either standard manual chest compressions or compressions performed with real-time feedback using the Cardio First Angel (CFA) device. The primary outcome was sustained return of spontaneous circulation (ROSC), and secondary outcomes were survival to ICU and hospital discharge.ResultsOne thousand four hundred fifty-four subjects were randomized; 900 were included. Sustained ROSC was significantly improved in the CFA group (66.7 vs. 42.4, P<0.001), as was survival to ICU discharge (59.8 vs. 33.6) and survival to hospital discharge (54 vs. 28.4, P<0.001). Outcomes were not affected by intra-group comparisons based on intubation status. ROSC, survival to ICU, and hospital discharge were noted to be improved in inter-group comparisons of non-intubated patients, but not intubated ones.ConclusionUse of the CFA compression feedback device improved event survival and survival to ICU and hospital discharge.Trial registrationThe study was registered with Clinicaltrials.gov (NCT02845011), registered retrospectively on July 21, 2016.
