PRIMARY OBJECTIVE: To determine whether using live actors to increase the reality of the scenario improves knowledge retention in Advanced Cardiac Life Support (ACLS) Courses. MAIN SECONDARY OBJECTIVES: To determine the effects of age, time since graduation from nursing or medicine, sex, medical specialty, and workplace in knowledge retention. METHODS:From December 2004 to October 2005, 19 selected ACLS courses were divided at random in two groups: group A (ACLS courses with conventional manikins plus live actors) and group B (ACLS courses with conventional manikins). The live actors vocalized appropriately to create more realistic scenarios. The participants' relevant theoretical knowledge was assessed before the course (pre-test), immediately after the course (post-test), and 6 months after the course (final-test). RESULTS:Four hundred and thirty-five participants were recruited and allocated at random allocated to either group A or B. Overall, the data of 225 participants (51.7%; 111 in group A and 114 in group B) who completed the entire sequence of pre-, post-, and final-tests were analysed. On univariate analysis, the use of live actors, workplace, gender, and healthcare provider profession did not affect pre-, post-, and final-test results (p>0.1). The results in all three tests correlated negatively with time since medical or nursing graduation (95% C.I. -0.53 to -0.17, -0.43 to -0.2, and -0.42 to -0.11, respectively, p<0.05) and age (and 95% C.I. -0.56 to -0.21, -0.42 to -0.2, and -0.38 to -0.07, respectively, p<0.05). CONCLUSION: The use of live actors did not affect knowledge retention in this group. Older age and a longer period since graduation were associated with the worst scores and the lowest levels of knowledge retention.
