目的 运用医疗失效模式与效应分析(HFMEA)对骨牵引针道感染的潜在影响因素进行分析和探讨,以降低针道感染的发生率.方法 将191例行骨牵引治疗的患者按住院号单、双分为对照组(95例)和试验组(96例).对照组按常规方法对患者进行护理;试验组应用HFMEA模式对针道感染的危险因素进行根本原因分析,改进整个护理操作流程.分析比较干预后两组患者事先风险数(RPN)及感染发生率.结果 试验组5个危险因子的RPN低于对照组;对照组感染发生率为3.15%(3/95),试验组感染发生率为1.04%(1/96),试验组针道感染率明显低于对照组,差异有统计学意义(P＜0.05).结论 HFMEA模式分析骨牵引针道感染原因准确,采取的控制感染措施能有效降低骨牵引针道感染风险.%Objective The potential influential factors of pin - tract infection resulted from the treatment of skeletal traction were analyzed and explored by applying healthcare failure mode and effect analysis ( HFMEA ), in order to reduce the rate of pin -tract infection. Methods According to the admission number, 191 patients undergone skeletal traction were randomly divided as control group ( 95 ) and trial group ( 96 ). The patients in the control group were given the conventional nursing; while those in the trial group were ever - improved nursing procedures according to the root cause analysis of risk factors for pin -tract infection by using HFMEA mode. After the intervention, the risk priority number ( RPN ) and the rate of pin - tract infection were analyzed. Results The RPNs of five risk factors in the trial group were obviously lower than those in the control group; and the rate of pin -tract infection in the trial group was 1. 04% ( 1/96 ), being obviously lower than 3. 15% ( 3/95 ) in the control group ( P <0. 05 ). Conclusion HFMEA mode can correctly analyze the cause of skeletal traction pin - tract infection, and the measures of controlling infection can effectively reduce the risk of infection.
