RESUMO

BACKGROUND: Previous evidence suggests that acute treatment with statins reduce atherosclerotic complications, including periprocedural myocardial infarction, but currently, there are no large, adequately powered studies to define the effects of early, high-dose statins in patients with acute coronary syndrome (ACS) and planned invasive management. OBJECTIVES: The main goal of Statins Evaluation in Coronary procedUres and REvascularization (SECURE-PCI) Trial is to determine whether the early use of a loading dose of 80 mg of atorvastatin before an intended percutaneous coronary intervention followed by an additional dose of 80 mg 24 hours after the procedure will be able to reduce the rates of major cardiovascular events at 30 days in patients with an ACS. DESIGN: The SECURE-PCI study is a pragmatic, multicenter, double-blind, placebo-controlled randomized trial planned to enroll around 4,200 patients in 58 different sites in Brazil. The primary outcome is the rate of major cardiovascular events at 30 days defined as a composite of all-cause mortality, nonfatal acute myocardial infarction, nonfatal stroke, and coronary revascularization. SUMMARY: The SECURE PCI is a large randomized trial testing a strategy of early, high-dose statin in patients with ACS and will provide important information about the acute treatment of this patient population.

RESUMO

CONTEXT: Studies have found that patients with acute coronary syndromes (ACS) often do not receive evidence-based therapies in community practice. This is particularly true in low- and middle-income countries. OBJECTIVE: To evaluate whether a multifaceted quality improvement (QI) intervention can improve the use of evidence-based therapies and reduce the incidence of major cardiovascular events among patients with ACS in a middle-income country. DESIGN, SETTING, AND PARTICIPANTS: The BRIDGE-ACS (Brazilian Intervention to Increase Evidence Usage in Acute Coronary Syndromes) trial, a cluster-randomized (concealed allocation) trial conducted among 34 clusters (public hospitals) in Brazil and enrolling a total of 1150 patients with ACS from March 15, 2011, through November 2, 2011, with follow-up through January 27, 2012. INTERVENTION: Multifaceted QI intervention including educational materials for clinicians, reminders, algorithms, and case manager training, vs routine practice (control). MAIN OUTCOME MEASURES: Primary end point was the percentage of eligible patients who received all evidence-based therapies (aspirin, clopidogrel, anticoagulants, and statins) during the first 24 hours in patients without contraindications. RESULTS: Mean age of the patients enrolled was 62 (SD, 13) years; 68.6% were men, and 40% presented with ST-segment elevation myocardial infarction, 35.6% with non-ST-segment elevation myocardial infarction, and 23.6% with unstable angina. The randomized clusters included 79.5% teaching hospitals, all from major urban areas and 41.2% with 24-hour percutaneous coronary intervention capabilities. Among eligible patients (923/1150 [80.3%]), 67.9% in the intervention vs 49.5% in the control group received all eligible acute therapies (population average odds ratio [OR(PA)], 2.64 [95% CI, 1.28-5.45]). Similarly, among eligible patients (801/1150 [69.7%]), those in the intervention group were more likely to receive all eligible acute and discharge medications (50.9% vs 31.9%; OR(PA),, 2.49 [95% CI, 1.08-5.74]). Overall composite adherence scores were higher in the intervention clusters (89% vs 81.4%; mean difference, 8.6% [95% CI, 2.2%-15.0%]). In-hospital cardiovascular event rates were 5.5% in the intervention group vs 7.0% in the control group (OR(PA), 0.72 [95% CI, 0.36-1.43]); 30-day all-cause mortality was 7.0% vs 8.4% (ORPA, 0.79 [95% CI, 0.46-1.34]). CONCLUSION: Among patients with ACS treated in Brazil, a multifaceted educational intervention resulted in significant improvement in the use of evidence-based therapies.

RESUMO

Translating evidence into clinical practice in the management of acute coronary syndromes (ACS) is challenging. Few ACS quality improvement interventions have been rigorously evaluated to determine their impact on patient care and clinical outcomes. We designed a pragmatic, 2-arm, cluster-randomized trial involving 34 clusters (Brazilian public hospitals). Clusters were randomized to receive a multifaceted quality improvement intervention (experimental group) or routine practice (control group). The 6-month educational intervention included reminders, care algorithms, a case manager, and distribution of educational materials to health care providers. The primary end point was a composite of evidence-based post-ACS therapies within 24 hours of admission, with the secondary measure of major cardiovascular clinical events (death, nonfatal myocardial infarction, nonfatal cardiac arrest, and nonfatal stroke). Prescription of evidence-based therapies at hospital discharge were also evaluated as part of the secondary outcomes. All analyses were performed by the intention-to-treat principle and took the cluster design into account using individual-level regression modeling (generalized estimating equations). If proven effective, this multifaceted intervention would have wide use as a means of promoting optimal use of evidence-based interventions for the management of ACS.
