A reduction in hospital readmissions may improve quality and reduce costs. The Centers for Medicare and Medicaid Services has initiated a national effort to measure and publicly report on the conduct of discharge planning. We know little about how U.S. hospitals perform on the current discharge metrics, the factors that underlie better performance, and whether better performance is related to lower readmission rates.
We examined hospital performance on the basis of two measures of discharge planning: the adequacy of documentation in the chart that discharge instructions were provided to patients with congestive heart failure, and patient-reported experiences with discharge planning. We examined the association between performance on these measures and rates of readmission for congestive heart failure and pneumonia.
We found a weak correlation in performance between the two discharge measures (r=0.05, P<0.001). Although larger hospitals performed better on the chart-based measure, smaller hospitals and those with higher nurse-staffing levels performed better on the patient-reported measure. We found no association between performance on the chart-based measure and readmission rates among patients with congestive heart failure (readmission rates among hospitals performing in the highest quartile vs. the lowest quartile, 23.7% vs. 23.5%; P=0.54) and only a very modest association between performance on the patient-reported measure and readmission rates for congestive heart failure (readmission rates among hospitals performing in the highest quartile vs. the lowest quartile, 22.4% vs. 24.7%; P<0.001) and pneumonia (17.5% vs. 19.5%, P<0.001).
Our findings suggest that current efforts to collect and publicly report data on discharge planning are unlikely to yield large reductions in unnecessary readmissions.
减少医院再入院率可以提高医疗质量并降低成本。医疗保险和医疗补助服务中心已发起一项全国性工作,以衡量和公开报告出院计划的执行情况。我们对美国医院在当前出院指标上的表现、表现更好的背后因素以及更好的表现是否与较低的再入院率相关知之甚少。
我们根据出院计划的两项衡量标准来考察医院的表现:图表中记录向心力衰竭患者提供出院指导的充分性,以及患者对出院计划的体验。我们考察了这两项措施的表现与心力衰竭和肺炎再入院率之间的关联。
我们发现这两项出院措施之间的表现存在微弱的相关性(r=0.05,P<0.001)。尽管较大的医院在基于图表的措施上表现更好,但较小的医院和护士人员配备水平较高的医院在患者报告的措施上表现更好。我们发现基于图表的措施的表现与心力衰竭患者的再入院率之间没有关联(在表现最高四分位数的医院与表现最低四分位数的医院之间,再入院率分别为 23.7%和 23.5%;P=0.54),而患者报告的措施的表现与心力衰竭患者的再入院率之间只有非常微弱的关联(在表现最高四分位数的医院与表现最低四分位数的医院之间,再入院率分别为 22.4%和 24.7%;P<0.001)和肺炎(分别为 17.5%和 19.5%;P<0.001)。
我们的研究结果表明,目前收集和公开报告出院计划数据的努力不太可能大幅减少不必要的再入院。
