Management of hypercholesterolemia: Practice patterns for primary care providers and cardiologists

This retrospective study, conducted as part of a private practice quality assurance process for patients with coronary artery disease (CAD), compares practice patterns in the LIFEHELP lipid clinic and non-lipid clinic settings at the Heart Institute of St. Petersburg. Quality assurance parameters included documentation of low-density lipoprotein (LDL) cholesterol, initiation of lipid-lowering therapy, and achievement of the Second National Cholesterol Education Program (NCEP II) goal for CAD patients of LDL cholesterol less than or equal to 100 mg/dL. A total of 934 patient charts with ICD-9 codes of 410-414 for ischemic heart disease were randomly selected and reviewed by a utilization review nurse. A higher level of documentation and treatment of elevated LDL cholesterol to NCEP II goal in CAD patients was found for those followed in the lipid clinic. Among non-lipid clinic physicians, cardiologists documented and treated elevated LDL cholesterol more frequently than primary care physicians. Women and the elderly subgroups received improved care in the lipid clinic setting. Screening activities and risk-factor management by cardiologists within a lipid clinic, therefore, demonstrated an improved standard of care that came closer to achieving national guidelines in the secondary prevention of CAD.
