Physician Recognition of Hypercholesterolemia in Patients Undergoing Peripheral and Carotid Artery Revascularization

Numerous studies have shown that patients with peripheral and carotid atherosclerosis have a high prevalence of hyperlipidemia, and clinical trials using either angiography or ultrasonography have now demonstrated regression of both femoral and carotid arterial plaque during lipid-lowering therapy. However, whether patients with peripheral and carotid atherosclerosis receive adequate attention to lipid risk factors has not been studied. To evaluate physician recognition and management of hypercholesterolemia in these two patient populations, we reviewed the charts of 80 consecutive patients undergoing revascularization for symptomatic peripheral and carotid occlusive disease at a university medical center between 1990 and 1993. Physician practices were assessed for each patient by noting whether hypercholesterolemia was (1) screened for during the hospitalization and, if present, (2) documented as a problem, (3) managed in-hospital, or (4) given appropriate intervention at discharge. While 73% of patients received some type of lipid case-finding perioperatively, less than one quarter of these were assessed for hyperlipidemia by the physician during the initial history. Moreover, of the 66% of screened patients found to be hypercholesterolemic, only 16% had documentation of the problem, only 24% received in-hospital management, and only 13% received intervention at discharge. These findings suggest that patients with documented peripheral and carotid atherosclerotic vascular disease probably receive inadequate attention to lipid risk factors and indicate the need for greater awareness and management of lipid disorders in these two patient populations by all involved physicians.
