surgical site infection is associated with longer postoperative hospital stays. We explored factors associated with longer postoperative hospital stays among patients in the surgical ward of a primary rural hospital in Ethiopia, where laboratory facilities for microbiological confirmation of surgical site infections were not available.
an observational study was performed for patients ≥ 18 years of age who underwent elective or emergency surgery from 22 June 2017 to 19 July 2018. Data were taken from paper-based medical records and patient interviews. The primary outcome was postoperative length of hospital stay. Data were analyzed by multivariable linear regression using Stata software, version 13.
seventy-five patients were enrolled, sociodemographic data was obtained from 14 of these patients by interview, and 44 patients had complete outcome and covariate data and were included in regression analysis. Median length of preoperative hospital stay was 3.0 (interquartile range 2.0) days. Postoperative length of hospital stay was longer by 3.8 days (95% confidence interval (CI) 1.05-6.55; p=0.008), 4.7 days (95% CI 1.64-7.66; p=0.004), and 5.9 days (95% CI 2.70-9.02; p=0.001), for patients 35-54 years, 55-64 years and the 65+ years respectively, compared to patients who were 18-34 years of age. Patients who received preoperative antibiotics stayed 5.3 days longer (95% CI 1.67-8.87; p=0.005) compared to those who were not given preoperative antibiotics.
age and improper use of preoperative antibiotics compound the risk for postoperative length of stay. Infection prevention protocols, including staff training, and surveillance for surgical site infections are critical for improving hospital outcomes.
手术部位感染与术后住院时间延长有关。我们探讨了在埃塞俄比亚一家农村初级医院的外科病房中，由于缺乏微生物学确认手术部位感染的实验室设施，与术后住院时间延长相关的因素。
对 2017 年 6 月 22 日至 2018 年 7 月 19 日期间接受择期或急诊手术的年龄≥18 岁的患者进行了一项观察性研究。数据来自纸质病历和患者访谈。主要结局是术后住院时间。使用 Stata 软件版本 13 通过多变量线性回归分析数据。
共纳入 75 例患者，其中 14 例通过访谈获得了社会人口学数据，44 例患者具有完整的结局和协变量数据，并纳入回归分析。术前住院时间中位数为 3.0（四分位距 2.0）天。与 18-34 岁的患者相比，35-54 岁、55-64 岁和 65 岁以上的患者术后住院时间分别延长 3.8 天（95%置信区间 1.05-6.55；p=0.008）、4.7 天（95%置信区间 1.64-7.66；p=0.004）和 5.9 天（95%置信区间 2.70-9.02；p=0.001）。接受术前抗生素治疗的患者比未接受术前抗生素治疗的患者住院时间延长 5.3 天（95%置信区间 1.67-8.87；p=0.005）。
年龄和术前抗生素的不当使用会增加术后住院时间的风险。感染预防方案，包括工作人员培训和手术部位感染监测，对于改善医院结局至关重要。
