中文摘要

医疗系统面临的一大核心挑战,是如何在及时救治重症患者的同时,高效管理复杂程度较低的病例。医院常常因这两类需求而负担过重,难以兼顾并有效配置资源。许多国家已引入替代性的全天候(24/7)设施来缓解医院压力、改善患者结果,但关于其影响的证据依然有限。我们利用丰富的行政数据,评估了巴西公共资助医疗体系中引入独立急诊中心(UPAs)的效果。我们发现,UPAs使医院门诊诊疗操作减少了30%,使门诊敏感疾病所致住院减少了24%–37%,从而使医院能够将资源集中于手术、产科住院等更复杂的病例,这类病例增加了25%。我们观察到住院死亡率下降了13%,尤其体现在重症监护病房以及最适合医院治疗的病症中。虽然部分死亡转移到了UPA,但人口层面死亡率下降了1.8%,不过这一结果并不具有统计显著性。我们的研究结果表明,急诊护理的中间层级如何重塑患者分流、缓解医院拥堵,并在负荷过重的公共医疗系统中改善医院绩效。

Abstract

A core challenge for healthcare systems is ensuring timely care for critical conditions while efficiently managing lower-complexity cases. Hospitals, often overburdened by both, struggle to balance these demands and allocate resources effectively. Many countries have responded by introducing alternative 24/7 facilities to relieve hospital strain and improve patient outcomes, yet evidence on their impact remains limited. We evaluate the introduction of freestanding Emergency Care Centers (UPAs) within Brazil’s publicly funded health system, leveraging rich administrative data. We find that UPAs reduced hospital outpatient procedures by 30% and hospital admissions for ambulatory-sensitive conditions by 24–37%, enabling hospitals to focus on more complex cases, such as surgeries and obstetric admissions, which increased by 25%. We observe a 13% reduction in inpatient mortality, particularly in intensive care and for conditions best suited to hospital treatment. While some deaths were displaced to UPAs, there was a decline in population-level mortality of 1.8%, although this is not statistically significant. Our findings show how an intermediate tier of emergency care reshapes patient sorting, alleviates hospital congestion, and improves hospital performance in an overstretched public health system.
