A total of 1504 consecutive abdominal operations were studied prospectively over a five year period. The incidence of wound (2.8%) and intraperitoneal (0.8%) infections was low compared with contemporary reports. It is difficult to justify modifying existing practice on the basis of small controlled clinical trials when information from accurate audit discloses results superior to those of experimental studies.
在五年期间对总共1504例连续的腹部手术进行了前瞻性研究。与当代报告相比,伤口感染率(2.8%)和腹腔内感染率(0.8%)较低。当准确的审计信息显示结果优于实验研究时,很难基于小型对照临床试验来证明改变现有做法的合理性。
