The Implications of Blood Transfusions for Patients With Non–ST-Segment Elevation Acute Coronary Syndromes: Results From the CRUSADE National Quality Improvement Initiative
In a large contemporary population of patients with non–ST-segment elevation acute coronary syndromes (NSTE ACS), we sought to describe blood transfusion rates (overall and in patients who did not undergo coronary artery bypass grafting [CABG]), patient characteristics and practices associated with transfusion, variation among hospitals, and in-hospital outcomes in patients receiving transfusions.The use of antithrombotic agents and invasive procedures reduces ischemic complications but increases risks for bleeding and need for blood transfusion in patients with NSTE ACS.We evaluated patient characteristics and transfusion rates in the overall population (n = 85,111) and determined outcomes and factors associated with need for transfusion in a subpopulation of patients who did not undergo CABG (n = 74,271) from 478 U.S. hospitals between January 1, 2001, and March 31, 2004.A total of 14.9% of the overall and 10.3% of the non-CABG population underwent transfusion during their hospitalization. Renal insufficiency and advanced age were strongly associated with the likelihood of transfusion. Interhospital transfusion rates varied significantly. Non-CABG patients who received transfusions had a greater risk of death (11.5% vs. 3.8%) and death or reinfarction (13.4% vs. 5.8%) than patients who did not undergo transfusion.Transfusion is common in the setting of NSTE ACS, and patients who undergo transfusion are sicker at baseline and experience a higher risk of adverse outcomes than their nontransfused counterparts. Given the wide variation in transfusion practice, further efforts to understand patient and process factors that result in bleeding and need for transfusion in NSTE ACS are needed
Evolution in Cardiovascular Care for Elderly Patients With Non–ST-Segment Elevation Acute Coronary Syndromes: Results From the CRUSADE National Quality Improvement Initiative
OBJECTIVES This study evaluated the impact of age on care and outcomes for non-ST-segment elevation acute coronary syndromes (NSTE ACS). BACKGROUND Recent clinical trials have expanded treatment options for NSTE ACS, now reflected in guidelines. Elderly patients are at highest risk, yet have previously been shown to receive less care than younger patients. METHODS In 56,963 patients with NSTE ACS at 443 U.S. hospitals participating in the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines (CRUSADE) National Quality Improvement Initiative from January 2001 to June 2003, we compared use of guidelines-recommended care across four age groups: <65, 65 to 74, 75 to 84, and ≥85 years. A multivariate model tested for age-related differences in treatments and outcomes after adjusting for patient, provider, and hospital factors. RESULTS Of the study population, 35% were ≥75 years old, and 11% were ≥85 years old. Use of acute anti-platelet and anti-thrombin therapy within the first 24 h decreased with age. Elderly patients were also less likely to undergo early catheterization or revascularization. Whereas use of many discharge medications was similar in young and old patients, clopidogrel and lipid-lowering therapy remained less commonly prescribed in elderly patients. In-hospital mortality and complication rates increased with advancing age, but those receiving more recommended therapies had lower mortality even after adjustment than those who did not. CONCLUSIONS Age impacts use of guidelines-recommended care for newer agents and early in-hospital care. Further improvements in outcomes for elderly patients by optimizing the safe and early use of therapies are likely
