RESUMEN
Whilst CPR training is widely recommended, quality of performance is infrequently explored. We evaluated whether a checklist can be an adequate tool for chest compression quality assessment in schoolchildren, compared with a real-time software. This observational study (March 2019-2020) included 104 schoolchildren with no previous CPR training (11-17 years old, 66 girls, 84 primary schoolchildren, 20 high schoolchildren). Simultaneous evaluations of CPR quality were performed using an observational checklist and real-time software. High-quality CPR was determined as a combination of 70% correct maneuvers in compression rate (100-120/min), depth (5-6 cm), and complete release, using a real-time software and three positive performance in skills using a checklist. We adjusted a multivariate logistic regression model for age, sex, and BMI. We found moderate to high agreement percentages in quality of CPR performance (rate: 68.3%, depth: 79.8%, and complete release: 91.3%) between a checklist and real-time software. Only 38.5% of schoolchildren (~14 years-old, ~54.4 kg, and ~22.1 kg/m2) showed high-quality CPR. High-quality CPR was more often performed by older schoolchildren (OR = 1.43, 95%IC:1.09-1.86), and sex was not an independent factor (OR = 1.26, 95%IC:0.52-3.07). For high-quality CPR in schoolchildren, a checklist showed moderate to high agreement with real-time software. Better performance was associated with age regardless of sex and BMI.
RESUMEN
Bystander training in cardiopulmonary resuscitation (CPR) is crucial to improve the victims' survival and quality of life after sudden cardiac arrest. This observational study aimed to determine the success rate of 2 different programs of CPR training for children, adolescents, and adults in school communities. We assessed the development and acquisition of the following CPR skills: checking local safety, assessing victim's responsiveness, calling for help, assessing victim's breathing, and performing chest compression (hands and straight arms placement on the chest, compression velocity, depth, and chest release) using a 40-minute program with handmade manikins or the 120-minute program using intermediate-fidelity manikins. There were 1,630 learners (mean age 16 years, 38% male) in the 40-minute program, and 347 learners (mean age 27 years, 32% male) in the 120-minute program. The lowest successful pass rate of learners that developed CPR skills was 89.4% in the 40-minute program and 84.5% in the 120-minute program. The chances of success increased with age in the same program (compression rate and depth). The success rate also increased with the more extended and intermediate-cost program at the same age (assessing victim's responsiveness, calling for help, and assessing the victim's respiration). In conclusion, a 40-minute and cheaper (low-cost handmade manikin) CPR program was adequate to develop and acquire the overall CPR skills for ≥89% at school communities, independently of gender. However, some individual CPR skills can be further improved with increasing age and using the longer and intermediate-cost program.
