Attitude changes of general practitioners towards lowering LDL cholesterol

Area of Science:

• Cardiology
• Public Health
• General Practice

Background:

• Clinical studies confirm cholesterol lowering benefits for reducing coronary complications.
• Physician attitudes present a significant barrier to implementing these findings in clinical practice.

Purpose of the Study:

• To assess general practitioners' attitudes towards initiating drug therapy for lowering low-density-lipoprotein (LDL) cholesterol.
• To evaluate changes in these attitudes between 1996 and 1997.

Main Methods:

• A postal questionnaire survey was conducted among general practitioners in Helsinki in 1996 and 1997.
• Physicians reported LDL cholesterol thresholds for initiating drug therapy across four distinct patient profiles.
• Longitudinal analysis compared responses between the two survey years and across patient categories.

Main Results:

• Significant improvements in physician attitudes towards LDL cholesterol lowering were observed from 1996 to 1997 across all patient groups.
• In 1997, over 50% of GPs would initiate therapy at LDL < 5.0 mmol/l for primary prevention and < 4.0 mmol/l for secondary prevention.
• Treatment initiation thresholds were significantly more aggressive for secondary prevention and older patients compared to primary prevention.

Conclusions:

• General practitioners' attitudes toward LDL cholesterol management have become more proactive.
• Despite improvements, current physician attitudes are not yet optimal for managing coronary and older atherosclerotic patients effectively.
