IntroductionResuscitation training increases bystander's ability to perform basic life support (BLS) with an automated external defibrillator (AED) immediately after training. However, several studies indicate that resuscitation skills decay rapidly.MethodsThis study evaluates retention of BLS/AED skills three months after an initial study comparing acquisition of BLS/AED skills among laypersons immediately after training with a two-stage versus four-stage teaching technique.ResultsThere was no difference in retention of BLS/AED skills (pass rate 10.8% versus 10.9%, respectively, p=1) three months after training. Total average number of skills adequately performed (of 17) was 13.3 versus 13.7 among laypersons trained with a two-stage and a four-stage technique, respectively. No difference was found in quality of chest compressions and rescue breaths between the two groups.ConclusionThree months after training, this study found no difference in retention of BLS/AED skills among laypersons taught using a two-stage compared to a four-stage teaching technique.
