BACKGROUND: Many physicians are not adhering to the recommendations found in evidence-based guidelines for the treatment of acute myocardial infarction (AMI). Physicians who practise in tertiary care settings may show better adherence to guideline recommendations than physicians who practise in other settings. OBJECTIVE: To determine whether there is an association between the practice setting of admission for AMI and discharge prescriptions for cardiac drugs recommended in evidence-based guidelines. PATIENTS AND METHODS: Discharge prescription data from a prospective cohort of patients with AMI admitted at five tertiary care (n=250) and five community hospitals (n=331) in Quebec from December 1996 to November 1998 were examined. RESULTS: The proportions of patients who were prescribed recommended drugs at tertiary care hospitals compared with those at community hospitals were as follows: beta-blockers (78% versus 74%, respectively; 95% CI around the difference - 4% to 11%), lipid-lowering drugs (45% versus 39%, respectively; 95% CI - 2% to 15%) and angiotensin-converting enzyme (ACE) inhibitors (44% versus 57%, respectively; 95% CI - 22% to - 5%). In adjusted analyses, practice setting was not associated with the prescription of beta-blockers (odds ratio [OR] for tertiary care 1.36; 95% CI 0.82 to 2.24) or lipid-lowering drugs (OR for tertiary care 1.06; 95% CI 0.67 to 1.68). However, tertiary care admission reduced the likelihood of ACE inhibitor prescription (OR 0.50; 95% CI 0.32 to 0.77). This association may have been due to the increased likelihood of ACE inhibitor prescription for patients with hypertension at community hospitals (OR 2.13; 95% CI 1.23 to 3.67). The results also showed that older patients were less likely to be prescribed beta-blockers or lipid-lowering drugs, women were less likely to be prescribed beta-blockers and patients with diabetes mellitus were less likely to be prescribed lipid-lowering drugs (OR 0.45; 95% CI 0.23 to 0.89). CONCLUSION: No strong association was found between the practice setting of admission for AMI and discharge prescriptions for cardiac drugs recommended in evidence-based guidelines. Prescription rates for recommended drugs were high, yet results suggest that there is room for improvement with regard to patients with diabetes, women and older patients.
