Surgical site infections (SSI) are rare but severe complications after total joint arthroplasty (TJA). Decolonization measures prior to elective orthopedic surgeries have shown to reduce the risk of SSI with Staphylococcus aureus (S. aureus). To determine the efficacy of universal decolonization with Polyhexanide on SSI rates with a focus on Staphylococcus aureus in patients with TJA. Patients scheduled for elective hip or knee TJA in 5 participating certified orthopedic centers were included between 2015 and 2018 into this before and after study. Data on patients, surgeries and infections were prospectively collected. CDC-criteria were used to define and categorize Infections within 90 days after surgery. From January 2017 on, patients received decolonization sets containing Polyhexanide. Patients performed a 5 day decolonization regimen starting 4 days prior to surgery which included wipes, nasal decontamination and oral solution. Thirteen thousand, three hundred fifteen patients received TJA. During intervention 4437 decolonization sets were distributed among 7175 patients. Overall SSI rates increased from 0.68 /100 surgeries to 0.91/ 100 surgeries after implementation of the intervention (IRR 1.32; 95% CI 0.90–1.96). Time series analysis identified an increasing trend of SSI prior to the intervention. After implementation overall SSI rates plateaued. Regression analysis revealed surgery during intervention period to be an independent risk factor for developing a SSI (OR 1.34; 95%CI 1.18–1.53). Initial SSI rates due to S. aureus were 0.24/100 surgeries and decreased to 0.14/100 surgeries (IRR 0.57; 95% CI 0.25–1.22) after introduction of decolonization. Regression analysis revealed surgery during intervention period to be an independent protective factor for developing a SSI with S. aureus (OR 0.57, 95% CI: 0.33–0.99). Overall deep S. aureus SSI decreased significantly from 0.22/100 surgeries to 0.00/100 surgeries in patients adherent to protocol (IRR 0.00, 95% CI 0.00–.85). Universal decolonization with Polyhexanide did not reduce overall surgical site infections, but was effective in reducing Staphylococcus aureus - surgical site infections following elective joint arthroplasty. Polyhexanide could extend the list of alternatives to already established decolonization strategies. The trial was registered at the German Registry for clinical studies www.drks.de ( DRKS00011505 ).

聚己内酯通用术前去定植术在初次关节置换术中对手术部位感染的疗效。多中心研究前后

手术部位感染 (SSI) 是全关节置换术 (TJA) 后罕见但严重的并发症。选择性整形外科手术前的去定植措施已显示可降低金黄色葡萄球菌 (S. aureus) 发生 SSI 的风险。以 TJA 患者的金黄色葡萄球菌为重点,确定使用聚己胺进行普遍去定植对 SSI 率的影响。在 2015 年至 2018 年期间,计划在 5 个参与认证的骨科中心进行选择性髋关节或膝关节 TJA 的患者被纳入研究前后。前瞻性收集有关患者、手术和感染的数据。CDC 标准用于定义和分类手术后 90 天内的感染。从 2017 年 1 月起,患者接受了含有聚己内酯的去定植套装。患者在手术前 4 天开始执行 5 天的去定植方案,其中包括湿巾、鼻腔去污和口服溶液。一万三千、三百十五名患者接受了 TJA。在干预期间,4437 套去定植集分布在 7175 名患者中。实施干预后,总体 SSI 率从 0.68/100 次手术增加到 0.91/100 次手术(IRR 1.32;95% CI 0.90–1.96)。时间序列分析确定了干预前 SSI 的增加趋势。实施后,整体 SSI 率趋于平稳。回归分析显示,干预期间的手术是发生 SSI 的独立危险因素(OR 1.34;95%CI 1.18–1.53)。由金黄色葡萄球菌引起的初始 SSI 率为 0.24/100 次手术,然后降至 0.14/100 次手术(IRR 0.57;95% CI 0.25–1。22) 在引入非殖民化之后。回归分析显示,干预期间的手术是发生金黄色葡萄球菌 SSI 的独立保护因素(OR 0.57,95% CI:0.33–0.99)。总体深部金黄色葡萄球菌 SSI 从 0.22/100 次手术显着降低到遵守协议的患者的 0.00/100 次手术(IRR 0.00,95% CI 0.00–.85)。聚己内酯的普遍去定植并没有减少整体手术部位感染,但可以有效减少金黄色葡萄球菌 - 选择性关节置换术后的手术部位感染。聚己内酯可以将替代品清单扩展到已经建立的非殖民化战略。该试验在德国临床研究注册处注册 www.drks.de (DRKS00011505)。回归分析显示,干预期间的手术是发生金黄色葡萄球菌 SSI 的独立保护因素(OR 0.57,95% CI:0.33–0.99)。总体深部金黄色葡萄球菌 SSI 从 0.22/100 次手术显着降低到遵守协议的患者的 0.00/100 次手术(IRR 0.00,95% CI 0.00–.85)。聚己内酯的普遍去定植并没有减少整体手术部位感染,但可以有效减少金黄色葡萄球菌 - 选择性关节置换术后的手术部位感染。聚己内酯可以将替代品清单扩展到已经建立的非殖民化战略。该试验在德国临床研究注册处注册 www.drks.de (DRKS00011505)。回归分析显示,干预期间的手术是发生金黄色葡萄球菌 SSI 的独立保护因素(OR 0.57,95% CI:0.33–0.99)。总体深部金黄色葡萄球菌 SSI 从 0.22/100 次手术显着降低到遵守协议的患者的 0.00/100 次手术(IRR 0.00,95% CI 0.00–.85)。使用聚己内酯进行普遍去定植并没有减少整体手术部位感染,但可以有效减少金黄色葡萄球菌 - 选择性关节置换术后的手术部位感染。聚己内酯可以将替代品清单扩展到已经建立的非殖民化战略。该试验在德国临床研究注册处注册 www.drks.de (DRKS00011505)。总体深部金黄色葡萄球菌 SSI 从 0.22/100 次手术显着降低到遵守协议的患者的 0.00/100 次手术(IRR 0.00,95% CI 0.00–.85)。聚己内酯的普遍去定植并没有减少整体手术部位感染,但可以有效减少金黄色葡萄球菌 - 选择性关节置换术后的手术部位感染。聚己内酯可以将替代品清单扩展到已经建立的非殖民化战略。该试验在德国临床研究注册处注册 www.drks.de (DRKS00011505)。总体深部金黄色葡萄球菌 SSI 从 0.22/100 次手术显着降低到遵守协议的患者的 0.00/100 次手术(IRR 0.00,95% CI 0.00–.85)。聚己内酯的普遍去定植并没有减少整体手术部位感染,但可以有效减少金黄色葡萄球菌 - 选择性关节置换术后的手术部位感染。聚己内酯可以将替代品清单扩展到已经建立的非殖民化战略。该试验在德国临床研究注册处注册 www.drks.de (DRKS00011505)。但在减少选择性关节置换术后金黄色葡萄球菌 - 手术部位感染方面有效。聚己内酯可以将替代品清单扩展到已经建立的非殖民化战略。该试验在德国临床研究注册处注册 www.drks.de (DRKS00011505)。但在减少选择性关节置换术后金黄色葡萄球菌 - 手术部位感染方面有效。聚己内酯可以将替代品清单扩展到已经建立的非殖民化战略。该试验在德国临床研究注册处注册 www.drks.de (DRKS00011505)。
