The wound infection rates, nasal carriage rates, and nasal colonization rates were studied in a recently built surgical unit for two years when it was first opened. Five years later a further two-year period of study was undertaken.Judging by the incidence of postoperative wound infection, as far as both Staphylococcus pyogenes and Gram-negative organisms are concerned, there is no evidence that the environment has become less safe with use over the seven-year period since opening.
在一个新建的外科病房启用后的头两年对其伤口感染率、鼻腔带菌率和鼻腔定植率进行了研究。五年后又进行了为期两年的研究。就化脓性葡萄球菌和革兰氏阴性菌而言,从术后伤口感染的发生率判断,没有证据表明自启用以来的七年里随着使用该环境变得不那么安全了。
