Compliance with USPSTF recommendations on aspirin for prevention of cardiovascular disease in men

Area of Science:

• Cardiovascular disease prevention
• Preventive medicine guidelines
• Pharmacological interventions

Background:

• The United States Preventive Services Taskforce (USPSTF) recommended aspirin (ASA) for men aged 45-79 years in 2009 to reduce coronary artery disease (CAD) risk.
• This recommendation balanced the benefits of CAD risk reduction against the harm of gastrointestinal hemorrhage.
• Evaluating compliance with these guidelines is crucial for effective public health implementation.

Purpose of the Study:

• To assess adherence to the 2009 USPSTF aspirin recommendations among eligible men.
• To identify factors influencing physician prescription decisions for aspirin.
• To determine factors affecting patient compliance with prescribed aspirin therapy.

Main Methods:

• A cross-sectional study utilizing the 2011-2012 National Health and Nutrition Examination Survey (NHANES) dataset.
• Inclusion criteria: men aged 45-79 years with no prior history of CAD.
• Calculation of 10-year Framingham risk scores to determine aspirin eligibility; analysis of physician prescribing patterns and patient compliance.

Main Results:

• Approximately 91.5% of the study population qualified for aspirin therapy based on risk assessment.
• A significant proportion (65%) of eligible men were not advised to take aspirin by their healthcare providers.
• Among those prescribed aspirin, 30% were non-compliant, and 1.2% discontinued due to side effects. Inappropriately prescribed aspirin was also observed in those not qualifying.

Conclusions:

• Physician under-prescription and patient non-compliance were significant issues regarding the 2009 USPSTF aspirin guidelines.
• Younger age and fewer comorbidities were associated with both under-prescription and lower patient compliance.
• These findings suggest potential challenges in implementing updated 2016 USPSTF recommendations due to similar influencing factors.
