目的评价视频自学(VSI)与传统课堂教学(TCI)对公众心肺复苏(CPR)技能获得与保持的效果。方法采用荟萃分析(meta分析)方法,计算机检索Cochrane图书馆、PubMed、EMBASE等数据库,收集公众CPR培训的随机对照试验,进行文献质量评价后,应用RevMan 4.3软件进行敏感性和异质性分析,计算综合效应。结果共纳入10篇随机对照试验研究。据meta分析结果显示,VSI组与TCI组CPR技能合格率差异无统计学意义[OR=1.29,95%CI(0.44,3.75),P>0.05]。敏感性分析显示,研究对象年龄≥40岁者,VSI组CPR技能合格率明显优于TCI组[OR=4.66,95%CI(1.12,19.32),P<0.05]。培训结束后2~3个月,VSI组CPR技能保持率优于TCI组[OR=2.25,95%CI(1.45,3.50),P<0.05];而培训结束后6~12个月,两组CPR技能保持率差异无统计学意义[OR=1.55,95%CI(0.75,3.21),P>0.05]。结论 VSI有利于年龄较大(≥40岁)者学习和掌握CPR技能;VSI比TCI更有利于公众短期CPR技能的保持,但对长期技能的保持效果并不能确定。建议进行多中心大样本随机对照试验研究,以进一步验证VSI对CPR技能的长期保持效果。
Objective To evaluate the effect of video self-study (VSI) and traditional classroom teaching (TCI) on the acquisition and maintenance of public CPR skills. Methods A meta-analysis (meta-analysis) method was used to search databases such as the Cochrane Library, PubMed and EMBASE, and collect the randomized controlled trials of public CPR training. After evaluating the quality of the literature, RevMan 4.3 software was used to analyze the sensitivity and heterogeneity. Calculate the combined effect. Results A total of 10 randomized controlled trials were included. According to the results of meta-analysis, there was no significant difference in pass rate of CPR between VSI group and TCI group [OR = 1.29, 95% CI (0.44, 3.75), P> 0.05]. Sensitivity analysis showed that the passing rate of CPR skills of VSI group was significantly better than that of TCI group [OR = 4.66, 95% CI (1.12, 19.32), P <0.05]. 2 to 3 months after the end of training, the CPR skill retention rate of VSI group was better than that of TCI group [OR = 2.25,95% CI (1.45, 3.50), P <0.05]; while 6-12 months after training, CPR skill retention rate difference was not statistically significant [OR = 1.55,95% CI (0.75,3.21), P> 0.05]. Conclusions VSI is beneficial for learning and mastery of CPR skills in older adults (≥40 years). VSI is more beneficial to the public maintaining short-term CPR skills than TCI, but its effect on long-term skills can not be ascertained. A multicenter randomized controlled trial is recommended to further validate the long-term effect of VSI on CPR skills.
