Abstract 226: Adherence to Aspirin Therapy for Primary Prevention of Coronary Artery Disease and Cerebrovascular Accidents
Cardiovascular disease is the leading cause of death in the United States. One simple, overlooked, and easily available therapy can reduce this risk: aspirin. Low dose aspirin reduces the risk of first time myocardial infarction (MI) in men and ischemic stroke (CVA) in women. The American Heart Association recommends anti-platelet therapy for those with an ASCVD (atherosclerotic cardiovascular disease) risk score> 7.5%. The aim of our study was to determine adherence to guidelines regarding aspirin therapy for primary prevention of myocardial infarction and stroke in our resident clinic. A retrospective chart review of randomized patients with risk factors for CAD and CVA seen at Ambulatory Center in Newark, NJ, between 5/1/12 and 10/29/13 was conducted. Those with contraindications to aspirin therapy were excluded.
Over 400 charts were reviewed; 281 met inclusion criteria. Per chart review, only 30% (84/281) of all at-risk patients were taking aspirin. When assessing various risk factors, 44.9% (35/78) of males ages 45-79; 24% (28/116) of females ages 55-79 (95% Confidence Interval [CI] = +-5.9%); 35.7% (51/143) of those with 10-year ASCVD risk score greater than 7.5% (95% CI = +-7.9%); 36.1% (39/108) of diabetic patients (95% CI 95% = +-9.2%); 32.8% (66/201) of those on anti-hypertensive medication (95% CI = +- 6.5%) and 29.3% (36/123) of those with a smoking history were taking aspirin (95% CI = +-8.2%). Of note, the number of women taking aspirin was statistically low as compared to men across all risk factors except for ASCVD score (p<0.01). This study revealed poor adherence to guidelines with regards to use of aspirin for primary prevention of cardiovascular disease and stroke in our resident clinic. In particular, adherence to aspirin therapy for women was strikingly low. However, our estimate may be somewhat low due to improper documentation of over the counter medications. We are implementing interventions to increase awareness of aspirin use such as educational campaigns for patients, mini-lectures for ambulatory resident cohorts, automated EMR reminders and adding aspirin therapy to health maintenance smart texts to achieve our goal of 100% compliance.
