Abstract

Rationale, aims and objectivesDyslipidaemia is a cardiovascular risk factor, and national screening and treatment guidelines have been established, but achievement of these remains inadequate. Multidisciplinary approaches, such as the chronic care model, have been applied to other chronic diseases and likely would be applicable to the management of dyslipidaemia. We therefore aimed to comprehensively study the different components of a multidisciplinary management approach to dyslipidaemia in a large health care system for patients at a high risk for cardiovascular events.MethodsAll patients at a Veterans Affairs Medical Center in the United States over 3 years with diabetes and/or coronary artery disease were included. Various clinical and demographic variables were collected and achievement of national cholesterol goals was determined. Univariate and multivariate analyses were conducted to determine the association of different health care variables with improved patient cholesterol guideline achievement.ResultsThere were 3559 patients in the study population and 51.0% had achieved national cholesterol goals. Multivariate analyses showed that patients who had achieved goals were more likely to have attended cardiology clinic [odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.3–2.01] and nutrition clinic (OR = 1.3, 95% CI = 1.04–1.7) and were more likely to have primary care providers who were nurse practitioners (OR = 1.6, 95% CI = 1.2–2.0), practicing full-time (OR = 1.8, 95% CI = 1.5–2.1) and at the main hospital-based clinics (OR = 1.5, 95% CI = 1.3–1.9).ConclusionsOur study identifies different components of a multidisciplinary approach to management of dyslipidaemia that are efficacious and these results may help guide future investment in this area.
