Introduction: It has been demonstrated that the use of feedback devices during CPR/AED course improves layperson’s CPR quality after the course. However, data on their use come mainly from single center studies and are limited to small populations of laypeople. Aim: Our aim was to create an open international registry to collect laypeople’s performance after a CPR/AED course carried out with the use of feedback devices. The registry started in May 2016 and is called “International Registry of Laypeople's CPR Performance After Training With Feedback Devices” (NCT03185260).
Methods: Each center collects laypeople’s performance of 1-minute of chest-compression only CPR registered at the end of a CPR/AED course in which feedback devices were used for at least 1 minute. All centers have to declare the course duration, the guidelines followed, the participants’ anthropometric variables and the feedback device used for the course and for the test.
Results: In the first 12 months 762 subjects’ performances were collected from 5 centers of 2 different nations. All the centers used Laerdal ResusciAnne QCPR both as feedback device and for the final test. The duration of the course ranged from 4 to 8 hours and the guidelines followed were American Heart Association for 3 centers and Swiss Resuscitation Council for 2 centers. 45% of the subjects were males, the mean age was 35 ± 13 years, the mean height 170.3 ± 9 cm, the mean weight 68.4 ± 15.2 kg and the mean BMI 23.4 ± 3.8 kg/m2. Regarding performance data, the mean compression rate was 114.8 ± 9.9 with a mean percentage of compressions at adequate rate of 67 ± 36.5, the mean compression depth was 52.4 ± 7.2 mm with a mean percentage of compressions with depth between 50 and 60 mm of 70.4 ± 36.5, the mean percentage of compressions with complete chest recoil was 79.9 ± 29.3 and the mean percentage of compressions with correct hand position was 96.5 ± 15.3.
Conclusions: To our knowledge, this is the largest registry of laypeople’s performance after a CPR course. The data from different centers demonstrated that High Quality CPR can be achieved by laypeople using feedback devices. We think that our registry could provide interesting data to improve CPR teaching to laypeople, which plays a key role to improve out-of-hospital cardiac arrest survival.
