Variations in cholesterol management practices of U.S. physicians

Area of Science:

• Cardiology
• Public Health
• Health Services Research

Background:

• Physician practices are influenced by nonclinical factors.
• Physician and patient characteristics impact cholesterol management.
• National data on cholesterol management practices is essential.

Purpose of the Study:

• To evaluate national cholesterol management practices among U.S. physicians.
• To identify predictors of cholesterol screening, counseling, and medication use.
• To assess the adoption of recommended cholesterol management guidelines.

Main Methods:

• Utilized a stratified, random sample of 2,332 office-based physicians from the 1991-1992 National Ambulatory Medical Care Surveys.
• Analyzed 56,215 adult office visits, focusing on cholesterol-related screening, counseling, and medication prescriptions.
• Employed multiple logistic regression to determine independent predictors of cholesterol management interventions.

Main Results:

• Cholesterol screening (2.8%) and counseling (1.2%) were infrequent for patients without hyperlipidemia; only 1 in 12 adults received annual screening.
• For patients with hyperlipidemia, testing occurred in 22.9%, counseling in 34.4%, and lipid-lowering medications in 23.1%.
• Screening likelihood increased with older age, cardiovascular disease risk factors, white race, and private insurance; testing and counseling varied by patient and physician characteristics.

Conclusions:

• Clinical conditions significantly influence cholesterol management, but variations by payment source, region, and specialty require further investigation.
• Low service volumes and observed variations suggest incomplete adoption of recommended cholesterol management practices by physicians.
• Further evaluation is needed to understand and address disparities in cholesterol care delivery.
