Abstract
Acute myocardial infarction is a silent killer for people worldwide, especially older adults who often experience atypical symptoms, causing late decision-making and a high mortality rate. The unrecognition of atypical symptoms, unconcerned about their risk, and not knowing how to deal with this critical situation are the barriers to a quick decision to visit the emergency department and delaying treatment, resulting in serious adverse outcomes. Therefore, specific and effective health education among older adults is needed. This double-blinded randomized controlled trial explored the effectiveness of health education by applying a role-play promoting decision-making ability program when expecting acute myocardial infarction occurrence among community-dwelling older adults. The participants were 96 community-dwelling older adults in central northeastern Thailand. We collected data between November 2021 and April 2022. The multi-stage sampling was applied to include participants. The intervention was the role-play promoting decision-making ability program and home visit. Outcomes were measured a week before attending and after finishing the intervention. T-tests, Mann-Whitney U test, Chi-square, and Wilcoxon Signed Rank test compared the outcomes between and within groups. Moreover, adjusted analysis was also demonstrated. Results revealed that participants who attended the program improved their knowledge, belief, and decision-making; only perceived susceptibility did not show improvement. Moreover, after demonstrating an adjusted analysis, the program participants had better knowledge about symptoms, perceived benefits, barriers, self-regulation, possible calling 1669, and first action. In conclusion, a role-play promoting decision-making ability program can promote knowledge, belief, and decision-making when expecting acute myocardial infarction occurrence among community-dwelling older adults. This study proved that role-play is one strategy to promote the program's effectiveness by inducing attention before giving older adults health information. Nurses and other healthcare professionals can implement this program as part of standard practice.Clinical Trial Registration Number: TCTR20210928004 on 28/09/2021.
