Development of perioperative risk warning index system for postoperative pulmonary infection in patients undergoing liver surgery based on Delphi method

Objective To establish perioperative risk warning index of postoperative pulmonary infection in patients undergoing liver surgery based on Delphi method. Methods Literature related to liver surgery and pulmonary infection was retrieved from Chinese(CNKI, Wanfang Data, Medlive)and foreign databases (NICE, PubMed, the Cochrane Library, Web of Science, EMbase, CINAHL). The draft of perioperative risk warning index for postoperative lung infection in patients undergoing liver surgery was developed by group discussion, and the draft was revised by two rounds of expert correspondence. Results The authority coefficients were 0. 856 and 0. 872 respectively. The Kendall harmony coefficients of the first, second and third indexes were 0. 216, 0. 279 and 0. 398 respectively. The perioperative risk warning indicators of postoperative pulmonary infection in patients undergoing liver surgery included 4 first-level indicators (basic condition, cardiopulmonary function, basic disease, and surgery-related), 11 second-level indicators, and 14 third-level indicators. Conclusion The experts participating in the letter consultation were highly motivated and authoritative, and the coordination degree of the letter consultation was good. The indicators established were helpful to improve the early identification of the risk of pulmonary infection in patients with liver surgery. (目的 基于德尔菲法构建肝脏手术患者术后肺部感染围术期风险预警指标。方法 检索中文数据库(中国知网、万方数据库、医脉通)和外文数据库(NICE、PubMed、the Cochrane Library、Web of Science、EMbase、CINAHL), 获取与肝脏手术、肺部感染相关的文献, 采用小组讨论法制定肝脏手术患者术后肺部感染围术期风险预警指标草案, 通过两轮专家函询法对草案进行修订。结果 两轮函询专家权威系数分别为0. 856, 0. 872; 一级指标、二级指标、三级指标专家肯德尔和谐系数分别为0. 216, 0. 279, 0. 398; 制定的肝脏手术患者术后肺部感染围术期风险预警指标包括一级别指标4项(基本情况、心肺功能、基础疾病、手术相关)、二级指标11项、三级指标14项。结论 参与函询的专家积极性及权威性高, 函询意见协调程度好, 构建的指标有助于提高临床医护人员对肝脏手术患者术后肺部感染风险的早期识别。)
