Policy Points: Policymakers seek to transform the US health care system along two dimensions simultaneously: alternative payment models and new models of provider organization. This transformation is supposed to transfer risk to providers and make them more accountable for health care costs and quality. The transformation in payment and provider organization is neither happening quickly nor shifting risk to providers. The impact on health care cost and quality is also weak or nonexistent. In the longer run, decision makers should be prepared to accept the limits on transformation and carefully consider whether to advocate solutions not yet supported by evidence.
There is a widespread belief that the US health care system needs to move "from volume to value." This transformation to value (eg, quality divided by cost) is conceptualized as a two-fold movement: (1) from fee-for-service to alternative payment models; and (2) from solo practice and freestanding hospitals to medical homes, accountable care organizations, large hospital systems, and organized clinics like Kaiser Permanente.
We evaluate whether this transformation is happening quickly, shifting risk to providers, lowering costs, and improving quality. We draw on recent evidence on provider payment and organization and their effects on cost and quality.
Data suggest a low prevalence of provider risk payment models and slow movement toward new payment and organizational models. Evidence suggests the impact of both on cost and quality is weak.
We need to be patient in expecting system improvements from ongoing changes in provider payment and organization. We also may need to look for improvements in other areas of the economy or to accept and accommodate prospects of modest improvements over time.
政策要点:政策制定者试图同时沿两个维度改变美国的医疗保健系统:替代支付模式和新的提供者组织模式。这种转变旨在将风险转移给提供者,并使他们对医疗成本和质量更负责。支付和提供者组织的转变既没有迅速发生,也没有将风险转移给提供者。对医疗保健成本和质量的影响也很微弱或不存在。从长远来看,决策者应该准备接受转变的局限性,并仔细考虑是否提倡尚未得到证据支持的解决方案。
人们普遍认为,美国的医疗保健系统需要从“量到质”转变。这种向价值的转变(例如,质量除以成本)被概念化为双重运动:(1)从按服务收费转变为替代支付模式;(2)从个体执业和独立医院转变为医疗之家、责任制医疗组织、大型医院系统和像 Kaiser Permanente 这样的有组织诊所。
我们评估这种转变是否正在迅速发生,是否将风险转移给提供者,是否降低成本,以及是否提高质量。我们借鉴了关于提供者支付和组织及其对成本和质量的影响的最新证据。
数据表明,提供者风险支付模式的流行率较低,向新的支付和组织模式的转变缓慢。有证据表明,这两者对成本和质量的影响都很微弱。
我们需要耐心等待从提供者支付和组织的持续变化中期待系统的改善。我们可能还需要在经济的其他领域寻找改善,或者接受并适应随着时间的推移适度改善的前景。
