Prevalence of adequate control of increased serum low-density lipoprotein cholesterol in self-pay or Medicare patients versus Medicaid or private insurance patients followed in a University General Medicine Clinic

In a study of 514 patients with increased serum low-density lipoprotein (LDL) cholesterol followed in a general medicine clinic at a university hospital, the serum LDL cholesterol in patients with coronary heart disease (CHD), other atherosclerotic vascular disease, or diabetes mellitus was100 mg/dl in 219 of 276 patients (79%) with Medicaid or private insurance and in 28 of 67 self-pay or Medicare patients (42%) without pharmaceutical coverage (p0.001). The serum LDL cholesterol was130 mg/dl in patients with 2+ risk factor and a 10-year risk for CHD ofor =20% or160 mg/dl in patients with a 0 to 1 risk factor, and a 10-year risk for CHD of10% in 54 of 141 patients (38%) with Medicaid or private insurance and in 5 of 30 self-pay or Medicare patients (17%) (p0.025).
