Complication registration in patients after peripheral arterial bypass surgery.

The objective of this study was to describe the kinds of complications and their incidence after peripheral vascular surgery of the lower limb, coding for causes and effect on the patient. In this prospective study, a standardized complication registration system was used at the Red Cross Hospital, The Hague. All patients (n = 373) receiving an infrainguinal bypass graft during the period January 1, 1996 to December 31, 1999 were included. All postoperative complications occurring during admission were coded. In 29% of the patients 153 complications were coded. Early occlusions of the graft occurred 36 times, wound infections 21 times and postoperative hemorrhages 20 times. Postoperative retention of urine was seen most frequently of all nonspecific complications (n = 22). In 43 cases the patient needed medication or a blood transfusion for his complication. In 42 cases a re-intervention was necessary. Complications led to a prolonged stay in the hospital in 20 cases. Six patients died during admittance (mortality 1.6%). An error in surgical therapy and error in nonsurgical therapy were the cause of the complication in 108 cases (out of 153). The advantage of this complication registration is that it describes all complications, not just the specific ones. Furthermore, by categorizing all complications we force ourselves to look for errors in nonsurgical therapy and surgical technique and to describe the effect of the complication.
