Abstract
We compared the length of hospitalization of 329 patients undergoing femoropopliteal bypass during 1982 with that allowed under Medicare's diagnosis-related groups (DRGs) for major reconstructive vascular surgery (DRGs 110 and 111). The mean length of stay was found to be related to the patients' age, increasing at a rate of about 1 percent per year. The site of distal anastomosis, a factor not considered in establishing the criteria for these DRGs, was also important. The lengths of stay for above-the-knee popliteal, below-the-knee popliteal, and tibioperoneal anastomoses were significantly different (F = 3.31; P<0.05), with lengths of stay increasing for more distal anastomoses. More distal anastomoses were also associated with increased rates of postoperative morbidity, reoperation, and mortality.
