Aspirin Use in Patients Undergoing Preoperative Evaluation for Minor Surgery

We found that 505 patients were treated with aspirin (16.8%), 312 men (61.8%) and 193 women (38.2%) (P < .05). In the group of patients treated with aspirin we found that 379 subjects—254 men (67%) and 125 women (33%)—were treated with aspirin according to guidelines for prevention of cardiovascular disease. In addition, 32 patients (all men) were treated with aspirin outside of guideline indications. Seven hundred ninety-eight patients (26.6%) that needed aspirin or antiplatelet therapy due to their cardiovascular risk were not treated, despite having no contraindication or allergy, and 126 patients discontinued aspirin despite appropriate indication.
