摘要

审计和反馈系统在许多情况下显著改善了医疗保健,它们似乎是通过刺激竞争而不是通过命令和控制来起作用的。方法西弗吉尼亚医学研究所(WVMI)是医疗保险指定的质量改进组织(QIO),定期收集导致医疗保险受益人住院的五种常见疾病(急性心肌梗死(AMI)、心力衰竭、肺炎、中风和心房颤动)的质量信息。从1998年到2001年,向西弗吉尼亚州所有44家急症护理医院提供了书面和口头的质量绩效报告。结果所有指标在全州范围内均有所改善。有几种——例如,急性心肌梗死患者出院时服用阿司匹林,肺炎患者接种肺炎球菌疫苗——提高了10个以上的绝对百分比。15项质量指标中有14项有显著改善(p <.05,配对t检验)。在整个研究期间,在大型医院评估的13项指标中,有7项在反馈前质量没有显著趋势,但有显著提高(p <.05,卡方表示趋势)。讨论报告的质量指标变化可以代表西弗吉尼亚州医疗保险受益人的重要健康收益。大部分的改善是在医院收到反馈之后才发生的。

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.
