Using statewide audit and feedback to improve hospital care in West Virginia.

BACKGROUND: Audit and feedback systems have significantly improved medical care in numerous settings, and they appear to work by stimulating competition rather than through command and control. METHODS: The West Virginia Medical Institute (WVMI), a Medicare-designated Quality Improvement Organization (QIO), periodically collected quality information on five common conditions (acute myocardial infarction [AMI], heart failure, pneumonia, stroke, and atrial fibrillation) that cause hospitalization in Medicare beneficiaries. All 44 acute care hospitals in West Virginia were offered written and orally presented reports of quality performance from 1998 through 2001. RESULTS: All indicators appeared to improve statewide. Several--for example, aspirin at discharge for AMI patients and pneumococcal vaccine for pneumonia patients--improved by more than 10 absolute percentage points. Fourteen of 15 quality indicators showed significant improvement (p < .05, paired t-test) in all hospitals between the before- and after-feedback periods. Seven of 13 indicators assessed during the entire study in the largest hospitals showed no significant trends in quality before feedback but significant increases (p < .05, chi-square for trend) in the after-feedback period. DISCUSSION: The quality indicator changes reported can represent important health gains for West Virginia Medicare beneficiaries. Most of the improvement did not occur until after hospitals received feedback.

Beta blocker use in acute myocardial infarction in West Virginia.

This article describes our study of the use of beta blocker drugs in Medicare beneficiaries hospitalized for acute myocardial infarction in West Virginia between 1999 and 2000. We contrasted findings with the responses of practicing cardiologists in the state. The survey asked cardiologists to describe their recent patterns of beta blocker usage, to comment on the severity of generally recognized contraindications to beta blocker administration, and to speculate on reasons why West Virginia's rates of beta blocker use in AMI were lower than rates in most other states. Our study revealed that beta blocker use in AMI declined significantly with patient age, and that rates of use in larger hospitals exceeded those in smaller hospitals. There was little difference attributable to the specialty of the admitting physician. We also observed a positive association between the use of beta blockers in AMI and other appropriate interventions, such as the use of aspirin and revascularization. Cardiologists said they were using more beta blockers in AMI than five years ago, and speculated that high rates of chronic obstructive pulmonary disease and non-specialist physicians were responsible for low rates in West Virginia.
