The objective of this systematic review and meta-analysis is to assess and synthesize the global evidence on the level of nurses' knowledge and its determinants regarding the prevention of surgical site infections.
This systematic review and meta-analysis were conducted following strict methodological guidelines to ensure accuracy and reliability. Adhering to the 2020 PRISMA checklist, a systematic review and meta-analysis sought to establish the pooled proportion of nurse's knowledge and its determinants regarding surgical site infection prevention globally. MeSH terms and keywords were included in the search. Data extraction, quality assessment, and analysis followed established protocols. Heterogeneity and publication bias was assessed using STATA version 17.0.
A total of seventeen observational studies, with sample sizes ranging from 30 to 515 participants, were included in the final analysis in a global context. In this systematic review and meta-analysis, the pooled proportion of nurses with good knowledge of surgical site infection prevention is 62% (95% CI: 50-74%) when assessed using a dichotomous scale. However, when knowledge is measured using a three-point Likert scale, the pooled proportion of those with good knowledge drops to 46% (95% CI: 21-72%), with an additional 27% (95% CI: 16-38%) demonstrating fair or moderate knowledge.
This systematic review and meta-analysis is the first to synthesize data on nurses' knowledge of surgical site infection (SSI) prevention. The findings reveal poor knowledge levels, highlighting the need for targeted educational interventions globally. While the pooled odds ratio is not statistically significant, training, longer service years, and higher education improve SSI prevention knowledge by enhancing critical thinking, boosting confidence, and fostering adherence to evidence-based practices. Future research should focus on identifying factors influencing nurses' knowledge, particularly through longitudinal and interventional studies. Policymakers should incorporate international guidelines such as those recommended by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) into nursing curricula, supported by robust assessment tools and educator training, to improve knowledge transfer and implementation of best practices.
本系统评价和荟萃分析的目的是评估和综合全球范围内关于护士预防手术部位感染知识水平及其决定因素的证据。
本系统评价和荟萃分析遵循严格的方法学指南进行，以确保准确性和可靠性。遵循2020年PRISMA清单，进行系统评价和荟萃分析，以确定全球范围内护士预防手术部位感染知识及其决定因素的合并比例。检索中纳入了医学主题词和关键词。数据提取、质量评估和分析遵循既定方案。使用STATA 17.0版本评估异质性和发表偏倚。
在全球范围内，最终分析共纳入了17项观察性研究，样本量从30至515名参与者不等。在本系统评价和荟萃分析中，使用二分制量表评估时，对手术部位感染预防知识掌握良好的护士合并比例为62%（95%置信区间：50 - 74%）。然而，当使用三点李克特量表测量知识时，知识掌握良好者的合并比例降至46%（95%置信区间：21 - 72%），另有27%（95%置信区间：16 - 38%）表现出一般或中等知识水平。
本系统评价和荟萃分析首次综合了护士预防手术部位感染（SSI）知识的数据。研究结果显示知识水平较差，凸显了全球范围内针对性教育干预的必要性。虽然合并优势比无统计学意义，但培训、更长的服务年限和高等教育通过增强批判性思维、提升信心和促进遵循循证实践来提高SSI预防知识。未来的研究应侧重于确定影响护士知识的因素，特别是通过纵向和干预性研究。政策制定者应将世界卫生组织（WHO）和疾病控制与预防中心（CDC）等推荐的国际指南纳入护理课程，并辅以强大的评估工具和教育者培训，以改善知识传播和最佳实践的实施。
