Abstract

IntroductionThe purpose of this study is to investigate the effect of peer support on patient anxiety during the perioperative period of coronary angiography or percutaneous coronary intervention (PCI).Methods and analysisWe will search the following databases (PubMed, Web of Science, EMBASE, Cochrane Library, CINAHL, Clinicaltrials.gov, WHO International Clinical Trials Registry Platform, Google Scholar, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodicals Database, Chinese BioMedical Database and Wanfang Data) from the date of database inception to January 2019. Only randomised controlled trials will be included. For the data analysis, we will use RevMan V.5.3.5 software to evaluate the risk of bias, and the heterogeneity will be investigated using the Q statistic and P index. Additionally, the Grading of Recommendations Assessment, Development and Evaluation system will be used to assess the quality of evidence.Ethics and disseminationNo ethics approval will be required since this is a systematic review of published studies. We aim to report information regarding the effects of peer support on patient anxiety during the perioperative period of coronary angiography or PCI. This systematic review and meta-analysis will be submitted to a peer-reviewed journal for publication.PROSPERO registration numberCRD42019123290.
