Assessing the impact of immersive simulation on clinical performance during actual in-hospital cardiac arrest with CPR-sensing technology: A randomized feasibility study

Aim

Advanced simulation tools are increasingly being incorporated into cardiopulmonary resuscitation (CPR) training. These educational methods have been shown to improve trainee performance in simulated settings, but translation into clinical practice remains unknown for many aspects of CPR quality. This study attempts to measure the impact of simulation-based training for resuscitation team leaders on some measures of CPR quality during actual in-hospital resuscitation attempts.

Methods

In this prospective, randomized interventional cluster trial, internal medicine resident physicians (post-graduate year 2) were randomized using a random number generator to participate in a 4-h, immersive simulation course in cardiopulmonary resuscitation leadership using a high-fidelity simulator with video debriefing prior to serving as resuscitation team leaders at an academic medical center. Objective metrics of actual resuscitation performance were obtained from a CPR-sensing monitor/defibrillator.

Results

Thirty-two residents were randomized to receive simulation training or no additional training between April and July 2007 and data were collected following 98 actual resuscitations between July 2007 and June 2008. CPR quality from resuscitations led by 14 simulation-trained and 16 control group residents was similar in terms of mean compression depth (48 vs 49 mm; p = 0.53); compression rate (107 vs 104 min⁻¹; p = 0.30); ventilation rate (12 vs 12 min⁻¹; p = 0.45) and no-flow fraction (0.08 vs 0.07; p = 0.34).

Conclusions

Although we failed to detect any significant differences in objective measures of CPR quality, we have demonstrated that CPR-sensing technology has the potential for use in assessing the impact of a simulation curriculum on some aspects of actual resuscitation performance. A larger study, performed in a setting with lower baseline performance, would be required to assess the specific simulation curriculum.
