Effect of structured health education on quality of life and the end point of patients with coronary disease: a systematic review and Meta-analysis

Abstract

Objective We sought to evaluate the effect of structured health education on quality of life and the end point of patients with coronary disease with evidence-based method. Methods The Cochrane Library, Cochrane Database of Systematic Reviews (CDSR), Medline (OVID), Pubmed and Web of Science were searched to collect the randomized controlled trials (RCT) which mentioned the structured health education to CHD patients, the quality of the RCTs was evaluated by Jadad Score, then effective data were extracted and analyzed by Meta-analysis with RevMan 5.2 software. Results A total of 12 eligible studies of RCT were included in the study with Jadad Score evaluations at B level or above. There were 20 476 cases in the intervention group, 14 522 cases in the control group. Meta-analysis showed that the quality of life scores of the intervention group were significantly higher than those of the control group, weighted mean difference was 3.29, 95% CI (0.49-6.09). No significant difference was found in cardiac morbidity outcomes, re-hospitalization and the mortality rate, relative risk, 95% confidence interval were respectively 0.72 (0.50-1.04) , 0.98 (0.86-1.11) , 0.77 (0.58-1.03). Conclusions The structured health education can improve the quality of life of patients with coronary disease, but has no obvious effect on the cardiac morbidity outcomes, re-hospitalization and mortality rate. We suggest transitional care to be carried out in future research to decrease the incidence rates of them.
