Effect of positive event recording based on positive psychology on healthy behaviors and readmission rate of patients after PCI: a study protocol for a prospective, randomized controlled trial

Abstract

BackgroundUnhealthy behaviors of coronary heart disease (CHD) patients are closely related to the occurrence of major heart events, which increases the readmission rate and brings a heavy economic burden to families and society. Therefore, it is necessary for health care workers to take active preventive and therapeutic measures to keep or establish healthy behaviors of patients. Positive psychological intervention has been proved to be effective, but it has not been reported in the field of CHD in China. The purpose of this study is to explore the effects of positive event recording based on positive psychology on the healthy behaviors, readmission rate, and anxiety of patients with CHD, in order to provide new ideas for the development of secondary prevention strategies for CHD.MethodsThis is a prospective, single-center, randomized controlled trial (RCT). The subjects will be enrolled from the Department of Cardiology, the First Affiliated Hospital of Soochow University. There are 80 cases in total; according to the random number table, the subjects are randomly divided into the intervention group (n = 40) and the control group (n = 40). The patients in the intervention group will receive the intervention of recording positive events once a week for 3 months, while the patients in the control group receive conventional nursing. The primary outcomes will include healthy behaviors, readmission rate, and anxiety, and the secondary outcomes will include psychological capital, subjective well-being, and corresponding clinical laboratory indicators. The protocol was approved by the Medical Ethics Committee of Soochow University (approval no. SUDA20200604H01) and is performed in strict accordance with the Declaration of Helsinki formulated by the World Medical Association. All participants provide written informed consent.DiscussionThis study will verify whether positive event recording based on positive psychology can make patients maintain healthy behaviors, reduce readmission rate, and improve anxiety after PCI. Then, this study will provide new ideas and references for the development of secondary prevention strategies for patients with CHD.Trial registrationChinese Clinical Trials Registry 2000034538.
