Unplanned readmission rate and risk factors during 30-days after cardiac surgery in children: A systematic review with Meta-analysis / 中国小儿急救医学

ABSTRACT

Objective:To systematically evaluate the rate of unplanned readmissions for children at 30 days after cardiac surgery, the causes and risk factors for unplanned readmissions for children at 30 days after cardiac surgery.Methods:We searched PubMed, Embase, Web of Science, CBM, CNKI, Wanfang Data, and VIP database to collect studies from inception to August 15, 2020 of unplanned readmission of children after cardiac surgery.RevMan5.3 software was used for Meta-analysis.Results:A total of 13 studies, involving 81 633 patients were included.Meta-analysis results showed that the unplanned readmission rate of children 30 days after cardiac surgery was 11.5%(95% CI 9.9%-13%). Cardiac complications[24%(95% CI 10.7%-45.7%)], infections[18.7%(95% CI 13.7%-25.3%)], respiratory complications[18.0%(95% CI 10.7%-27.5%)], pleural effusion[11.5%(95% CI 8.3%-16.7%)], and gastrointestinal complications[12.3%(95% CI 8.3%-17.4%)] were the main reasons for unplanned 30-day readmission, with statistically significant differences( P<0.001). Genetic syndrome( OR=1.25, 95% CI 1.18-1.33, P<0.05) and postoperative hospital stay >14 days( OR=1.62, 95% CI 1.05-2.50, P<0.05) were risk factors for unplanned 30-day readmission. Conclusion:The incidence rate of unplanned readmission among the children 30 days after cardiac surgery is relatively high.Cardiac complications, infection, respiratory complications, pleural effusion, and gastrointestinal complications are the main reasons for 30-day unplanned readmission.The genetic syndrome and postoperative hospital stay >14 days in children 30 days after cardiac surgery are the risk factors for unplanned readmission.
