PURPOSE
Basic life support (BLS) training is crucial in improvement of cardiopulmonary resuscitation (CPR) outcomes. Many studies have demonstrated improvement of skills after BLS training but the skills significantly decrease over time. Our study aimed to evaluate the retention of knowledge and skills after training following 2010 BLS guidelines in second year medical students at Faculty of Medicine, Thammasat University.
MATERIALS AND METHODS
One hundred and forty-nine second-year medical students were enrolled in the prospective cohort study. Participants were tested for knowledge and skills of BLS prior to training (pre-test), immediately after training (post-test) and six months after training (retention test).
RESULTS
The mean scores of pre-test, immediate post-test and retention-test were 8.52 (SD 1.88), 12.12 (SD 1.52) and 10.83 (SD 1.95), respectively. Improvement in knowledge score post-test and retention test were 3.60 (95% CI 3.22,3.99 <0.001) and 2.31 (95% CI 1.92,2.70 <0.001) respectively, compared with pre-test score. In post-test, detection skill, activation skill and compression skill were improved 1.67 (95% CI 1.28,2.19 <0.001), 5.15 (95% CI 3.41,7.77 <0.001) and 3.88 times (95% CI 2.24,6.71 <0.001) compared with pre-test evaluation. Comparison between retention test and pre-test was improved detection skill 1.72 (95% CI 1.31,2.26 <0.001), activation skill 4.4 (95% CI 2.93,6.75 <0.001) and compression skill 2.56 (95% CI 1.44,4.57 =0.001). Knowledge decreased 1.29 times in retention test compared with post-test (95% CI -1.67,0.92 <0.001). In retention test, detection skill increased 1.03 times (95% CI 0.81,1.29 P = 0.810), activation skill decreased 0.86 times (95% CI 0.98,1.10 =0.24) and compression skill decreased 0.66 times (95% CI 0.45,0.98 =0.04) compared with post-test.
CONCLUSION
Knowledge and skills of BLS significantly improved after training in second year medical students. However, the knowledge decreased at 6 months after training although the BLS skills still remained.
目的
基础生命支持（BLS）培训对于改善心肺复苏（CPR）效果至关重要。许多研究表明，BLS培训后技能有所提高，但随着时间推移技能会显著下降。我们的研究旨在评估泰国法政大学医学院二年级医学生按照2010年BLS指南培训后知识和技能的保持情况。
材料与方法
149名二年级医学生参与了这项前瞻性队列研究。参与者在培训前（预测试）、培训后立即（后测试）以及培训后六个月（保持测试）接受了BLS知识和技能测试。
结果
预测试、即时后测试和保持测试的平均分数分别为8.52（标准差1.88）、12.12（标准差1.52）和10.83（标准差1.95）。与预测试分数相比，后测试和保持测试的知识分数提高分别为3.60（95%可信区间3.22,3.99 <0.001）和2.31（95%可信区间1.92,2.70 <0.001）。在后测试中，与预测试评估相比，检测技能、启动技能和按压技能分别提高了1.67倍（95%可信区间1.28,2.19 <0.001）、5.15倍（95%可信区间3.41,7.77 <0.001）和3.88倍（95%可信区间2.24,6.71 <0.001）。保持测试与预测试相比，检测技能提高了1.72倍（95%可信区间1.31,2.26 <0.001），启动技能提高了4.4倍（95%可信区间2.93,6.75 <0.001），按压技能提高了2.56倍（95%可信区间1.44,4.57 =0.001）。与后测试相比，保持测试中的知识下降了1.29倍（95%可信区间 -1.67,0.92 <0.001）。在保持测试中，与后测试相比，检测技能提高了1.03倍（95%可信区间0.81,1.29 P = 0.810），启动技能下降了0.86倍（95%可信区间0.98,1.10 =0.24），按压技能下降了0.66倍（95%可信区间0.45,0.98 =0.04）。
结论
二年级医学生培训后BLS知识和技能显著提高。然而，尽管BLS技能仍然存在，但培训后6个月知识有所下降。
