A modeling-based narrative intervention to promote timely care-seeking in patients with acute myocardial infarction: A pilot randomized controlled trial and feasibility analysis

摘要

Background: Prolonged delay in seeking medical attention for acute myocardial infarction persists as a global phenomenon, which limits effective disease management. The effects of previous mass-media campaigns and psycho-educations have been minimal. Aims: This study aimed to develop a modeling-based narrative intervention, and to examine its feasibility and preliminary effects on care-seeking behavioral intention in Chinese acute myocardial infarction patients. Methods: The modeling-based narrative intervention was developed by integrating updated research evidence and participants' perspectives. Ten patients were invited to co-design the intervention. The narrative approach was adopted to engage patients in a mental rehearsal of the decision-making process through a virtual acute myocardial infarction attack experience. A pilot randomized controlled trial was adopted to examine the feasibility and preliminary effects of this intervention. Results: A total of 67 participants were randomly allocated to receive either the modeling-based narrative intervention (n=34) or didactic education (n=33). The intervention was feasible and well-accepted by the participants as evidenced by high attendance and participant satisfaction. They considered the intervention as informative and interesting. The majority of the participants in the intervention group expressed that they enjoyed the intervention. Although the preliminary data showed non-significant between-group differences, a more prominent improving trend for acute myocardial infarction knowledge, care-seeking attitudes and beliefs in the intervention group were evident. Conclusions: This study is the first of its kind to adopt a novel narrative approach to optimize care-seeking behaviors among patients with acute myocardial infarction. The preliminary findings showed that this approach was highly feasible and accepted by patients.
