Infra-inguinal revascularization surgical site infections: Australasian benchmark.

Background: Infra-inguinal revascularization surgery remains one of the most commonly performed major vascular procedures in contemporary practice. Surgical site infections (SSI) are a common cause of morbidity in this patient cohort and generate high rates of limb loss and mortality when vascular graft involvement occurs. An overall reduction in North American SSI has been attributed to the establishment of national benchmarks. A comparable Australasian benchmark does not exist. The purpose of the present study was to assess the methods used by Australasian vascular units to determine SSI rates and to instigate the development of an acceptable benchmark. Methods: A structured questionnaire pertaining to SSI after infra-inguinal revascularization surgery was sent to 26 Australasian vascular units. Data requested included the number and type of lower extremity revascularization procedures performed. Units were also asked to report the methods employed for defining and detecting wound infections and to document their SSI rate. The incidence of SSI causation by methicillin-resistant Staphylococcus aureus (MRSA) was also sought. Results: The total number of revascularizations performed annually varied from 28 to 179 between units. The SSI rates ranged from 0 to 38%. The incidence of MRSA involvement varied from <1% to 56%. The SSI surveillance methodology varied considerably between units. Conclusions: The present study confirms the significant incidence of SSI after infra-inguinal revascularization surgery in contemporary vascular practice. Standardized definitions and surveillance protocols are required to facilitate inter- and intrahospital comparisons. A possible benchmark infection rate may be 10-20%.
