A multicenter controlled trial on knowledge and attitude about cardiopulmonary resuscitation among secondary school children in Malaysia

Abstract

BackgroundWe performed a multicenter controlled trial to assess the knowledge and attitude (KA) about cardiopulmonary resuscitation (CPR) among secondary school children in a district in Malaysia.MethodsThis was a prospective intervention study. The primary endpoint of the study was to determine the level of KA about resuscitation after CPR training. The six schools and classes from selected schools were chosen by randomization among the form three and four classes using sealed envelopes. A fully validated questionnaire consisting of three sections (sociodemographic, knowledge and attitude) was given to the pupils before and 2 weeks after the intervention. The intervention group was given a lecture, video show, pamphlet and 1-h practical session on CPR training. The control group received a placebo in order to overcome the learning effect. The maximum scores for the knowledge and attitude sections were 72 and 28, respectively. Repeated measures ANOVA analysis was used for specific objectives to determine the changes in knowledge and attitude level pre- and post-intervention for both study groups. P-values less than 0.05 were taken as significant at 95% confidence intervals.ResultsThe mean (SD) total knowledge scores for the intervention (n = 216) and control (n = 252) groups were 62.43 (13.68) and 62.29 (12.11), respectively (maximum score 72) (p > 0.05). On the other hand, the mean (SD) total attitude scores for the intervention and the control groups were 19.33 (4.51) and 17.85 (4.52), respectively (maximum score 28) (p < 0.001). There were significant differences in mean knowledge and attitude scores between the intervention and control groups with regard to time (pre- and post-intervention). The mean difference in knowledge and attitude scores between both study groups was 8.31 (p < 0.001) and 2.39 (p < 0.001), respectively.ConclusionsThe level of knowledge and attitudes of secondary school children was shown to be acceptable prior to the intervention. Furthermore, a brief CPR training program improved their level of knowledge and attitudes significantly as compared to those who had never been trained.
