Surgical site infections are one of the most important causes of healthcare associated infections (HCAI), accounting for 20% of all HCAIs. Surgical site infections affect 1% of joint replacement operations. This study was designed to assess whether theatre clothing is contaminated more inside or outside the theatre suite. Petri dishes filled with horse blood agar were pressed on theatre clothes at 0, 2, 4, 6 and 8 hours to sample bacterial contamination in 20 doctors whilst working in and outside the theatre suite. The results showed that there was greater bacterial contamination when outside the theatre suite at 2 hours. There were no differences in the amount of contamination at 4, 6 and 8 hours. This study suggests that the level of contamination of theatre clothes is similar both inside and outside the theatre setting.
手术部位感染是医疗相关感染（HCAI）最重要的原因之一，占所有HCAI的20%。手术部位感染影响1%的关节置换手术。本研究旨在评估手术室服装在手术室套房内部还是外部被污染得更严重。在20名医生于手术室套房内外工作时，分别在0、2、4、6和8小时将装有马血琼脂的培养皿按压在手术室服装上，以采集细菌污染样本。结果显示，在2小时时手术室套房外部的细菌污染更严重。在4、6和8小时时污染量没有差异。本研究表明，手术室服装在手术室环境内外的污染程度相似。
