Influence of clinical resources on the treatment of intermittent claudication.

Management of intermittent claudication varies between surgeons, even after adjustment for case-mix, and could be related to the availability of clinical resources. The aim of this study was to ascertain whether vascular surgeons perceived deficiencies in the resources available to them for the management of claudication and to determine whether an association existed between reported deficits and patient management. Over a six month period, 28 vascular surgeons in Scotland completed recording forms on their treatment intentions for 1,180 claudicants. Subsequently, the surgeons were interviewed about resources available for vascular surgery. The majority of surgeons reported deficiencies in resources, predominantly insufficient operating lists (71%) and staff shortages (71%). Although considered less important than clinical factors or patient wishes, resources were independently associated with treatment. Surgeons reporting insufficient operating lists were less likely to opt for surgical treatment (p < 0.05), and those working with reluctant or inexperienced radiologists were less likely to consider percutaneous transluminal angioplasty (p < 0.05) and more likely to offer surgery (p < 0.001). However, case-mix and resources explained only some of the variations in treatment. The residual variation was likely to reflect an underlying lack of agreement among surgeons on the most appropriate management of claudication. Randomised controlled trials to address this issue would be welcomed by the majority of surgeons questioned.
