A statewide collaborative initiative to improve the quality of care for patients with acute myocardial infarction and heart failure.

BACKGROUND: To enhance quality improvement, we created a unique statewide collaboration among 3 organizations: the Virginia Health Quality Center (Virginia's Medicare Quality Improvement Organization), the American College of Cardiology, and the American Heart Association. The goal was to improve discharge measures for acute myocardial infarction and heart failure. METHODS AND RESULTS: In 2004, 29 hospitals participated in the collaborative initiative. Using Medicare data submitted from 2004 through the second quarter of 2006, we analyzed adherence to individual discharge measures and all-or-none appropriate care measures for acute myocardial infarction, heart failure, and both. To control for differences in hospital characteristics, we were able to match 21 of the participating hospitals with 21 similar nonparticipating hospitals. In this paired analysis, the total appropriate care measure increased from 61% to 77% in participating hospitals compared with an increase from 51% to 60% in nonparticipating hospitals (P<0.0001). A generalized linear mixed model examining the full data set at the patient level failed to show a clear advantage among participating hospitals. Participating hospitals had higher baseline rates for most quality measures, suggesting a possible effect of a prior collaborative. Further analysis of only hospitals that participated in a prior collaborative showed that participants in the current collaborative initiative had higher rates of improvement for 7 of 10 quality measures and appropriate care measures for heart failure, acute myocardial infarction, or both (all P<0.05). CONCLUSIONS: We report a unique collaboration of a Medicare Quality Improvement Organization and 2 national organizations to address quality of care for acute myocardial infarction and heart failure. A composite measure of quality (the total appropriate care measure) improved more in the participating hospitals during the timeframe of the intervention, although the greater improvement in this and other measures in the participating hospitals appeared to be dependent on participation in a prior collaborative initiative.

Collaborative Initiatives in the Care of Early Stage Breast Cancer: Reduction in Variation of Breast-Conserving Therapy.

Breast-conserving therapy (BCT) has survival results comparable to those obtained with modified radical mastectomy (MST). However, studies suggest variations in the rates of breast-conserving therapy that are not explained by comorbidities or age. The Virginia Health Quality Center collaborated with 40 Virginia hospitals to address patterns of breast cancer treatment. Medicare Peer Review Organization data files were used to identify all Medicare beneficiaries with a primary diagnosis of breast cancer from January 1, 1992, through June 30, 1993. Explicit chart review was performed on a random sample of patients with early stage disease receiving either BCT or MST. At baseline, the BCT rate was 21.1% after controlling for access to radiation facilities, medical conditions, and demographic variables. Hospitals with the highest rates of appropriate BCT served as resources for the project. We provided data on BCT rates to 40 participating hospitals. Hospitals then submitted comprehensive plans to address the performance of BCT. A four-step cooperative improvement intervention was employed to initiate and sustain changes at the hospital level. Interventions included individual hospital feedback, dissemination of model cancer care processes at high-performing institutions, and integration of oncology services for breast cancer treatment decisions. One year after implementation, the overall BCT rate in Virginia increased to 25.5%. Hospitals with the lowest BCT rates increased their average rate from 6.6% to 21.2%. Middle tercile hospitals increased BCT rates by 10%. Variation between the lowest and highest terciles was reduced to 9%. Variation in BCT rates can be reduced by a collaborative program centered on addressing processes of care for breast cancer treatment for Medicare patients with early stage disease.
