A 21-month study involving 2181 clean and clean-contaminated general surgical procedures was performed to evaluate the effectiveness of a commercially available disposable gown and drape system vs a cotton system in reducing wound infection. The series in which the disposable spun-laced fiber system was used had a significantly lower overall infection rate (2.83% vs 6.5%) as well as better rates in clean (1.8% vs 3.8%) and clean-contaminated (4.8% vs 11.4%) procedures. This effect was independent of all other factors. The odds of developing a wound infection was 2 1/2 times higher with a cotton system than with a disposable system. Actual cost analysis from three types of hospitals showed lower costs with utilization of disposable gown and drape systems. Hospital charges were significantly higher for those patients developing wound infections. The results of the study demonstrated not only significant reduction in wound infection rates but also major cost savings when a disposable gown and drape system was used in the operating room.
一项为期21个月的研究，涉及2181例清洁和清洁-污染的普通外科手术，旨在评估一种市售一次性手术衣和手术单系统与棉质系统相比在减少伤口感染方面的有效性。使用一次性水刺纤维系统的系列手术总体感染率显著更低（2.83%对6.5%），在清洁手术（1.8%对3.8%）和清洁-污染手术（4.8%对11.4%）中的感染率也更低。这种效果与所有其他因素无关。使用棉质系统发生伤口感染的几率比使用一次性系统高2.5倍。来自三种类型医院的实际成本分析表明，使用一次性手术衣和手术单系统成本更低。发生伤口感染的患者的医院收费显著更高。研究结果表明，在手术室使用一次性手术衣和手术单系统不仅能显著降低伤口感染率，还能大幅节省成本。
