A cohort of 4515 surgical patients was selected from ten different surgical intervention groups, and 291 of 317 with a postoperative wound infection were matched 1:1 with controls with regard to intervention, sex and age. The mortality rate was investigated from the time of operation, with a follow-up period from 4 years 4 months to 8 years 4 months. Eighty-seven patients with a deep infection had a significantly increased mortality rate, with a risk ratio of 1.7. Without a distinction between superficial and deep infection the former might mask the higher mortality rate associated with the latter.
从十个不同的手术干预组中选取了4515名外科手术患者，317例术后伤口感染患者中的291例在干预措施、性别和年龄方面与对照组进行了1:1匹配。从手术时开始调查死亡率，随访期为4年4个月至8年4个月。87例深部感染患者的死亡率显著增加，风险比为1.7。若不区分浅表感染和深部感染，前者可能会掩盖与后者相关的较高死亡率。
