Objective Clinical trial investigators often assemble internal study monitoring committees ( SMC s) to measure individual or group adherence with trial performance benchmarks. We examined the processes and results of study monitoring in an international trial of out‐of‐hospital cardiac arrest. Methods We studied SMC operations for the Resuscitation Outcomes Consortium ( ROC ) Continuous Chest Compressions ( CCC ) trial, which compared continuous with interrupted chest compressions upon survival after out‐of‐hospital cardiac arrest. The SMC defined trial performance benchmarks, which included compliance with the intervention, cardiopulmonary resuscitation ( CPR ) process data availability and timely data completion. Trial investigators received monthly performance reports. We determined rates of trial noncompliance and suspension from the trial. Results ROC ‐ CCC enrolled a total of 23,711 subjects in the primary analysis population. Across 113 enrolling agencies, the SMC monitored performance for a total 2,367 agency‐months. Emergency medical services agencies were on probation for a total of 178 (7.5%) agency‐months. Fifty‐five agencies were placed on probation at least once, of which 78% improved their performance and were approved for continued participation in the trial. A total of 12 agencies were suspended from trial participation. Data monitoring resulted in high‐quality CPR (mean chest compression fraction = 0.80), 87% CPR process availability and timely data completion (75th and 95th percentiles prehospital data = 22 and 57 days; hospital data = 58 and 118 days). Conclusions Study monitoring procedures may play an important role in ensuring the performance quality in acute care clinical trials.
