Hand hygiene is a vital intervention to reduce health-care associated infections, but compliance remains low. The authors hypothesized that improvements in intraoperative hand hygiene compliance would reduce transmission of bacteria to surgical patients and reduce the incidence of postsurgical healthcare-associated infections.
The authors performed a controlled before-and-after study over 2 consecutive months. One hundred fourteen operative cases were enrolled. Two predesignated sites on the anesthesia machine were selected, decontaminated, and cultured via aseptic technique. These sites and the peripheral intravenous stopcock were cultured again after completion of the surgery. The treatment phase used a novel personal hand-decontamination device capable of recording hand-decontamination events.
There were no significant differences in patient location, age, or case duration and procedure type between groups. Use of the Sprixx GJ device (Harbor Medical Inc., Santa Barbara, CA) increased hourly hand decontamination events by 27-fold as compared with baseline rates (P < 0.002; 95% confidence interval, 3.3-13.4). Use of the device was associated with a reduction in contamination in the anesthesia work area and peripheral intravenous tubing. Intravenous tubing contamination was identified in 32.8% of cases in the control group versus 7.5% in the treatment group (odds ratio, 0.17; 95% confidence interval, 0.06-0.51; P < 0.01). Healthcare-associated infections rates were reduced in the device group (3.8%) as compared with the control group (17.2%) (odds ratio, 0.19; 95% confidence interval, 0.00-0.81; P = 0.02).
Improved hand hygiene compliance through the use of a novel hand sanitation strategy reduces the risk of intraoperative bacterial transmission. The intervention was associated with a reduction in healthcare-associated infections.
手部卫生是减少医疗相关感染的重要干预措施,但依从性仍然很低。作者推测,术中手部卫生依从性的提高将减少细菌向手术患者的传播,并降低术后医疗相关感染的发生率。
作者进行了一项连续两个月的前后对照研究。纳入了114例手术病例。通过无菌技术选择麻醉机上两个预先指定的部位,进行去污并培养。手术完成后,再次对这些部位和外周静脉旋塞进行培养。治疗阶段使用了一种能够记录手部去污事件的新型个人手部去污装置。
两组之间在患者位置、年龄、病例持续时间和手术类型方面没有显著差异。与基线率相比,使用Sprixx GJ装置(加利福尼亚州圣巴巴拉市海港医疗公司)使每小时手部去污事件增加了27倍(P < 0.002;95%置信区间,3.3 - 13.4)。使用该装置与麻醉工作区域和外周静脉输液管污染的减少有关。对照组32.8%的病例出现静脉输液管污染,而治疗组为7.5%(优势比,0.17;95%置信区间,0.06 - 0.51;P < 0.01)。与对照组(17.2%)相比,装置组的医疗相关感染率降低(3.8%)(优势比,0.19;95%置信区间,0.00 - 0.81;P = 0.02)。
通过使用新型手部卫生策略提高手部卫生依从性可降低术中细菌传播的风险。该干预措施与医疗相关感染的减少有关。
