[4 years of experiences with Karbase. A tool for quality development in vascular surgery]

Karbase, a Danish register for vascular surgery is presented with data from four years experience. The register consists of 65 variables centered on risk factors, the perioperative course as well as follow-up information. During the four-year period 1989-1992 a total of 4902 admissions were registered in 3810 patients. Surgery was performed during 4005 admissions. Output data from Karbase is presented with results on survival and postoperative complications, related to preoperative risk factors. The incidence of surgical wound infections was 3.9%, with a significant reduction during the years (p = 0.004). Karbase is now used by all vascular surgical units in Denmark. We conclude that the establishment of a continuous registration has been beneficial to the department. We have achieved valid data on treatment, outcome and complications in relation to individual risk factors. In the future the use of Karbase will be extended with the aim of further quality development, locally as well as nation wide.
