Abstract

Abstract Funding Acknowledgements Type of funding sources: None. Background/Introduction Recognizing symptoms of coronary artery disease (CAD) is important and challenging for CAD patients. Failure in detecting the related symptoms may lead to prehospital delay and decelerate the golden time of ischemic reperfusion. Purpose The purpose of the systematic review aims to evaluate types of education programs (through randomized control trial) of their effectiveness on reducing prehospital delay regarding CAD. Method The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was adopted to proceed this review. We searched from Pubmed, Cochrane Library, Scopus, CINAHL and EMBASE using a combination of free text words and Medical Subject Headings guided by the PICO framework. The abstracts and full-text screening were peer-reviewed by two reviewers. Results A total of 722 records were identified through database searching of which 11 randomized controlled trials were finally included into this review (n = 38773). The Cochrane Risk of Bias assessment tool 2.0 was utilized to examine the methodological quality of the included studies. Eight out of 11 studies conducted one by one individualized-educational intervention program (n = 11007); two studies used mass media campaign for the general public education program (n = 24753), and one study used the community-based educational intervention model (n = 3031). Of the three types of education models, the one to one individualized-educational intervention was found to be the most effective model to have reduce prehospital delay time shorter ranged from 30-60 minutes in the experimental groups while comparing to the control groups. Conclusion Individualized-educational program is found to be the most effective intervention to reduce prehospital delay for CAD patients. Health care providers are encouraged to apply one to one educational program in term of reducing prehospital delay for CAD patients both in clinical and community setting. Moreover, family members of high-risk patients are suggested to be included in a step-by-step action plan that eliminates the wait and see approach to reach medical support.
