Abstract
Introduction
Peripheral vascular disease is a major cause of death and disability. The extent to which volume influences outcome of lower limb (LL) vascular surgery remains unclear. This review evaluated the relationship between hospital/surgeon volume and outcome in LL surgery.
Methodology
Electronic databases; Medline, Embase, the Cochrane Library Databases, Science Citation Index, and CINAHL, proceedings from conferences, citations, and references of included studies were searched. Studies from Europe, of adults undergoing LL vascular surgery reporting outcomes by hospital or surgeon volume were included. Quality of studies was assessed using a modified ACROBAT-NRSI(Robins1) tool. Association between hospital/surgeon volume and outcome were summarised using tables.
Results
Nine studies from different European countries, comprising 67,445 patients who had undergone diverse LL surgeries were included. Increase in hospital/surgeon volume was associated with a decrease in amputations. The evidence on an association between hospital/surgeon volume and mortality was contradictory, but mortality and amputations may co-vary by hospital volume. There were an insufficient number of studies reporting on the other variables to draw firm conclusions; but their results suggest high volume hospitals may undertake more repeated surgeries/revascularisations and limb salvage. The impact of hospital/surgical volume on adverse events and length of hospitalisation could not be determined.
Conclusion
High volume hospitals/surgeons may undertake fewer amputations and mortality and amputations may co-vary. The finding that hospital and surgeon volume affected the number of secondary amputations has implications on re-organisation of vascular surgery services. However due to the small number and poor quality of some of the included studies, decisions on reorganisation of LL vascular surgery services should be supplemented by results from clinical audits. There is need for standardisation of definition of volume stratification of outcomes by patient’s clinical conditions.
