The Incidence of Unplanned Returns to the Operating Room After Peripheral Arterial Bypass Surgery and Its Value as Indicator of Quality of Care

Abstract

Background In recent years, a growing need has arisen to define possible indicators of quality of care. Methods To examine whether unplanned return to the operating room within 30 days after the initial procedure could serve as an indicator to assess quality of care in peripheral arterial bypass surgery, all bypass procedures performed between January 1996 and January 2004 were evaluated. Data were obtained from a prospectively kept hospital registration system. Results A total of 607 consecutive procedures were performed in 468 patients. The overall unexpected return to the operating room rate was 11.2%. Patients requiring peripheral arterial bypass surgery for critical ischemia with gangrene were significantly more at risk for an unplanned reoperation (20.2%) than patients with disabling claudication (2.1%) ( P < .0001). Patients requiring femorocrural bypass surgery (24.2%) were also more at risk than patients with a suprageniculate bypass procedure (5.2%) ( P < .0001). Conclusions Unplanned return to the operating room within 30 days after the initial operation can be a useful indicator of quality of care after peripheral arterial bypass surgery. However, a prospective, well-defined registration system to collect all data is essential. Furthermore, the severity of peripheral arterial disease and the type of procedure performed should be taken into account.
