IntroductionRelive is a serious game focusing on increasing kids and young adults' awareness on CPR. We evaluated the use of Relive on schoolchildren.MethodsA longitudinal, prospective study was carried out in two high schools in Italy over a 8-month period, divided in three phases: baseline, competition, and retention. Improvement in schoolchildren's CPR awareness, in terms of knowledge (MCQ results) and skills (chest compression (CC) rate and depth), was evaluated. Usability of Relive and differences in CC performance according to sex and BMI class were also evaluated.ResultsAt baseline, students performed CC with a mean depth of 31mm and a rate of 95 cpm. In the competition phase, students performed CC with a mean depth of 46mm and a rate of 111 cpm. In the retention phase, students performed CC with a mean depth of 47mm and a rate of 131 cpm. Thus, the training session with Relive during the competition phase affected positively both CC depth (p<0.001) and rate (p<0.001). Such an effect persisted up to the retention phase. CC depth was also affected by gender (p<0.01) and BMI class (p<0.01). Indeed, CC depth was significantly greater in male players and in players with higher BMI. Seventy-three percent of students improved their CPR knowledge as represented by an increases in the MCQ score (p<0.001). The participants perceived the Relive to be easy to use with effective feedback.ConclusionsRelive is an useful tool to spread CPR knowledge and improve CPR skills in schoolchildren.Copyright © 2017 Elsevier B.V.
