目的评估腹部手术部位感染的综合干预方案的效果。方法采用问卷调查和现场观察法,比较干预前后手术部位感染率、医务人员防控知识知晓率和措施执行率,评价干预效果。结果实施干预后腹部手术部位感染率由干预前5.88%下降至干预后3.72%,差异有统计学意义(χ2=4.64,P=0.031)。干预前医务人员手术部位感染防控知识的知晓率为60.20%,干预后知晓率为85.26%,差异有统计学意义(χ2=240.76,P=0.000)。干预后手卫生、无菌操作、合理用药等各项防控措施的执行率较干预前提高,差异均有统计学意义(P<0.05)。结论根据目标性监测数据和专家意见制定的综合干预方案,能有效推动医务人员落实各项防控措施,降低腹部手术部位感染发生率。
Objective To assess the effectiveness of a comprehensive intervention program for infection in abdominal surgery sites. Methods The questionnaire survey and field observation were used to compare the infection rate of the surgical site before and after the intervention, the awareness of prevention and control of medical staff and the implementation rate of the measures to evaluate the intervention effect. Results The infection rate of abdominal surgery site decreased from 5.88% before intervention to 3.72% after intervention, the difference was statistically significant (χ2 = 4.64, P = 0.031). Before the intervention, the awareness rate of infection prevention and control knowledge of surgical site was 60.20%, and the awareness rate was 85.26% after intervention. The difference was statistically significant (χ2 = 240.76, P = 0.000). After the intervention, the execution rate of various prevention and control measures such as hand hygiene, aseptic operation and rational drug use were all higher than those before intervention, with significant differences (P <0.05). Conclusion Based on the target monitoring data and expert opinion, the comprehensive intervention program can effectively promote medical staff to implement various prevention and control measures and reduce the incidence of abdominal surgical site infection.
