BACKGROUND: The impact of insurance coverage on the care of patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) is unclear. OBJECTIVE: To compare NSTE ACS care patterns by insurance type. DESIGN: Comparison of Medicaid patients younger than 65 years of age and Medicare patients 65 years of age or older with patients of similar age who have health maintenance organization (HMO) or private insurance coverage. SETTING: 521 U.S. hospitals participating in the CRUSADE (Can Rapid Risk Stratification of Unstable Angina Patients Suppress ADverse Outcomes with Early Implementation of the ACC [American College of Cardiology]/AHA [American Heart Association] Guidelines) quality improvement initiative from January 2001 through March 2005. PATIENTS: 37,345 NSTE ACS patients younger than 65 years of age and 59,550 patients 65 years of age or older. MEASUREMENTS: Guideline-recommended treatments, and in-hospital outcomes. RESULTS: Medicaid was the primary payer for 18.7% (6999 of 37,345) of patients younger than age 65 years, whereas Medicare was the primary payer for 67.5% (40,199 of 59,550) of patients age 65 years or older. Medicaid patients were statistically significantly less likely to receive short-term (less than 24 hours) medications and to undergo invasive cardiac procedures than patients covered by HMO and private insurance. They also had higher mortality rates (2.9% vs. 1.2%; adjusted odds ratio, 1.33; 95% CI, 1.08 to 1.63). Medications and invasive procedures were used to a similar extent in patients with Medicare and HMO or private insurance, and respective mortality rates were not significantly different (6.2% vs. 5.6%; adjusted odds ratio, 1.08; 95% CI, 0.99 to 1.18). LIMITATIONS: Self-pay patients and patients without insurance were not assessed. CONCLUSIONS: NSTE ACS patients with Medicaid (but not Medicare) as the primary payer were less likely to receive evidence-based therapies and had worse outcomes than patients with HMO or private insurance as the primary payer. The causes of these treatment differences and solutions for narrowing the gaps in quality require further investigation.
An American College of Cardiology (ACC)/American Heart Association (AHA) task force on practice guidelines in 2001 published evidence-based recommendations for performing percutaneous coronary interventions (PCIs). These guidelines grouped the indications for PCI into 4 classes (I, IIa, IIb, and III) based on analyses of risks and benefits. In a previous study, we found that clinical success and in-hospital adverse events varied by indications class. However, no adjustment for risk was used in those comparisons. The ACC/National Cardiovascular Data Registry (ACC-NCDR) previously developed a risk-adjustment model for the adverse event of in-hospital PCI mortality. We investigated how the 14 individual risk factors in the ACC-NCDR PCI mortality model might differ across the 4 indications classes and whether estimated mortality for each class approximated the observed mortality for that class. We analyzed the ACC-NCDR PCI database for January 1, 2001 to December 31, 2004. We excluded procedures performed for treatment of acute ST-segment elevation myocardial infarction; all others were included, yielding 559,273 procedures for analysis. An algorithm derived from the 2001 guidelines was used to assign procedures to an indications class. Increasing frequencies of risk components were observed across classes I, IIa, IIb, and III. Expected mortalities for each class calculated by the risk-adjustment model were close to observed values (expected 0.52%, 0.59%, 1.72%, and 1.96%, respectively; observed 0.49%, 0.63%, 1.88%, and 1.60%, respectively). In conclusion, the ACC-NCDR risk-adjusted mortality model can be linked to the ACC/AHA PCI guidelines, and together these produce mortality risk estimates by indications classes that are close to actual observed values. With further refinement, these methods should be able to be used as powerful analytic tools for quality assurance and appropriateness purposes.
BACKGROUND: Health-related quality of life (HRQOL) is an increasingly relevant outcome as the population ages and associated morbidities increase. The purpose of this study was to evaluate predictors of HRQOL among ethnically diverse women hospitalized for coronary heart disease (CHD) and determine the impact of a brief, educational intervention on HRQOL 6 months post-hospitalization. METHODS: Women (n = 160; mean age 63 years, 53% minority) admitted for CHD at three academic hospitals who completed a 6 month secondary prevention trial were studied. The SF-36 was administered at admission and 6 months. Multiple linear regressions were used to identify significant independent predictors of 6 month HRQOL. RESULTS: Significant improvements in HRQOL were noted from admission to 6 months post-hospitalization. Subjects reporting better HRQOL at 6 months included those who were employed, married, physically active, enrolled in cardiac rehabilitation, and not depressed. Women who received an educational intervention had significantly less bodily pain at 6 months compared with usual care in a model adjusted for baseline HRQOL and physical activity goal adherence (p = 0.04). CONCLUSIONS: Baseline HRQOL (8 SF-36 subscales), physical activity (3 SF-36 subscales) and marital status (1 SF-36 subscale) were the major determinants of HRQOL at 6 months post-hospitalization. Future interventions and preventive efforts should be targeted to women with CHD who have impaired HRQOL and may be at increased risk of poor clinical outcomes.
BACKGROUND: The extent to which national health quality improvement initiatives have altered reported treatment gaps among patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) is unknown. We sought to determine recent trends in adherence to guideline-based therapies for NSTE ACS. METHODS: We evaluated the treatment of patients with high-risk (positive cardiac markers and/or ischemic ST-segment changes) NSTE ACS enrolled in the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the ACC/AHA (American College of Cardiology/American Heart Association) Guidelines (CRUSADE) Quality Improvement Initiative from 2002 through 2004 (a total of 113 595 patients over 11 calendar quarters). We analyzed adherence to guideline-recommended therapies, including medications used in the acute care period (<24 hours after presentation), invasive procedures, in-hospital outcomes, and discharge therapies and interventions. RESULTS: The use of each class I guideline recommendation, as well as overall adherence to the guidelines, improved significantly (P<.001) during the study period. In the acute care setting, the use of antiplatelet agents increased by 5% and beta-blockers by 12%; at hospital discharge, the use of antiplatelet agents increased by 3% and beta-blockers by 8%. Heparin use in the acute care period increased by 6%, largely owing to a 9% increase in the use of low-molecular-weight heparin. Use of glycoprotein IIb/IIIa inhibitors in the acute care period also increased by more than 13%. At discharge, clopidogrel use increased by 22%, lipid-lowering agents by 11%, and angiotensin-converting enzyme inhibitors by 5%. While adherence improved, many patients still failed to receive 100% indicated treatments at the end of the study period. CONCLUSIONS: During the 4 years since the initial release of the ACC/AHA guidelines for NSTE ACS, adherence to class I recommendations has significantly improved among hospitals participating in CRUSADE. Still, further improvements are needed for optimal implementation of the these guidelines.

We evaluated temporal trends in the use of early (<48 hours) catheterization in patients with non-ST-segment elevation acute coronary syndromes with respect to baseline risk features since publication of the American College of Cardiology/American Heart Association guidelines, which include a class IA recommendation for an early invasive strategy for high-risk patients with non-ST-segment elevation acute coronary syndromes. Overall, we found that early catheterization use increased from 53% to 61% during the 3 years after the guidelines were released, but the increased use of early catheterization was highest (11%) in the group that was at lowest risk of predicted mortality, and it was lowest (6%) in the group at highest risk of predicted mortality who would potentially receive the most benefit from an aggressive treatment approach. In conclusion, despite the overall increase in the use of early catheterization, the gap between the use of an early invasive strategy in the highest and lowest risk patients remains large and tends to increase over time.

OBJECTIVES: We sought to characterize patterns of clopidogrel use before coronary artery bypass grafting (CABG) and examine the drug's impact on risks for postoperative transfusions among patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS). BACKGROUND: Adherence in community practice to American College of Cardiology/American Heart Association guidelines for clopidogrel use among NSTE ACS patients has not been previously characterized. METHODS: We evaluated 2,858 NSTE ACS patients undergoing CABG at 264 hospitals participating in the CRUSADE (Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the ACC/AHA Guidelines) Initiative. We examined the patterns of acute clopidogrel therapy and its association with bleeding risks among those having "early" CABG < or =5 days and again among those having "late" surgery >5 days after catheterization. RESULTS: Within 24 h of admission, 852 patients (30%) received clopidogrel. In contrast to national guidelines, 87% of clopidogrel-treated patients underwent CABG < or =5 days after treatment. Among those receiving CABG within < or =5 days of last treatment, the use of clopidogrel was associated with a significant increase in blood transfusions (65.0% vs. 56.9%, adjusted odds ratio [OR] 1.36, 95% confidence interval [CI] 1.10 to 1.68) as well as the need for transfusion of > or =4 U of blood (27.7% vs. 18.4%, OR 1.70, 95% CI 1.32 to 2.19). In contrast, acute clopidogrel therapy was not associated with higher bleeding risks if CABG was delayed >5 days (adjusted OR 1.18, 95% CI 0.54 to 2.58). CONCLUSIONS: Despite guideline recommendations, the overwhelming majority of NSTE ACS patients treated with acute clopidogrel needing CABG have their surgery within < or =5 days of treatment. A failure to delay surgery is associated with increased blood transfusion requirements that must be weighed against the potential clinical and economic impacts of such delays.
