BACKGROUND: Despite its prevalence, survival from out-of-hospital cardiac arrest remains low. High quality CPR has been associated with improved survival in cardiac arrest patients. In early 2014, a program was initiated to provide feedback on CPR quality to prehospital providers after every treated cardiac arrest.

OBJECTIVE: To assess whether individualized CPR feedback was associated with improved CPR quality measures in the prehospital setting.

METHODS: This before and after retrospective review included all treated adult out-of-hospital cardiac arrest in patients in an urban community. Data was compared prior to and after the initiation of the CPR feedback program. We compared the percent of encounters reaching the system defined benchmarks as well as the average values for compression fraction, compression rate, compression depth, and pre-shock pause in the before period compared to the after period.

RESULTS: There were 159 encounters in the before period and 117 in the after. Compared to the before group, the after group had higher average compression rates (111.2/min vs 113.8/min; p=0.042), increased compression depths (4.9cm vs 5.6cm; p<0.001), and increased rates of benchmark achievement for compression depth greater than 5cm (48.1% vs 72.6%; p<0.001). No significant difference was noted in pre-shock pause (21.4s vs 14.7s; p=0.068). Additionally, no difference was noted between groups for compression fraction, though goal achievement was high in both groups.

CONCLUSION: We found that individual CPR feedback is associated with marginally improved quality of CPR in the prehospital setting. Further investigation with larger samples is warranted to better quantify this effect.
