Surgical site infection is defined by the Centres for Disease Control and Prevention as a wound infection that occurs within 30 days of an operative procedure or within a year if an implant is left in place and the infection is thought to be secondary to surgery. It occupies 20% to 39% of all the infections acquired in hospitals. The aim of this study is to find out the prevalence of postoperative surgical site infections in the Department of General Surgery of a tertiary care centre.
A descriptive cross-sectional study on a total of 384 post-operative patients of abdominal surgery was conducted in the Department of General Surgery of a tertiary care centre from August 1, 2020 to July 30, 2021 with ethical approval from the Institutional Review Committee (Reference number: 267). Convenience sampling was done. Post-operative patients fulfilling the inclusion and exclusion criteria were included in the study. Data were entered in Microsoft Excel and analyzed using the Statistical Package for the Social Sciences version 21.0. Point estimate was done at a 95% Confidence Interval along with frequency and percentages for binary data and mean with standard deviation for continuous data.
Among 384 patients, the prevalence of surgical site infection was found to be 65 (16.92%) (13.15-20.65 at a 95% Confidence Interval). The patients had a mean age of 42.06±21.92 years.
The prevalence of surgical site infection was higher in our study in comparison to other similar studies conducted in similar settings.

根据疾病控制和预防中心的定义，手术部位感染是指在手术操作后 30 天内或在植入物仍留在原处且感染被认为是手术引起的一年内发生的伤口感染。它占据了所有在医院获得的感染的 20%至 39%。本研究的目的是了解三级护理中心普通外科手术后手术部位感染的发生率。
对 2020 年 8 月 1 日至 2021 年 7 月 30 日在三级护理中心普通外科接受腹部手术的 384 例术后患者进行了一项描述性横断面研究，该研究得到了机构审查委员会的伦理批准（编号：267）。采用便利抽样法。符合纳入和排除标准的术后患者被纳入研究。数据输入 Microsoft Excel 并使用统计软件包 21.0 进行分析。点估计在 95%置信区间内进行，同时对二项数据进行频率和百分比分析，对连续数据进行均值和标准差分析。
在 384 例患者中，手术部位感染的发生率为 65 例（16.92%）（95%置信区间为 13.15%至 20.65%）。患者的平均年龄为 42.06±21.92 岁。
与在类似环境中进行的其他类似研究相比，我们的研究中手术部位感染的发生率更高。
