Long-term acute care hospitals (LTCHs) are common sites of postacute care for patients recovering from severe respiratory failure requiring mechanical ventilation (MV). However, federal payment reform led to the closure of many LTCHs in the US, and it is unclear how closure of LTCHs may have affected upstream care patterns at short-stay hospitals and overall patient outcomes.
To estimate the association between LTCH closures and short-stay hospital care patterns and patient outcomes.
DESIGN, SETTING, AND PARTICIPANTS: This retrospective, national, matched cohort study used difference-in-differences analysis to compare outcomes at short-stay hospitals reliant on LTCHs that closed during 2012 to 2018 with outcomes at control hospitals. Data were obtained from the Medicare Provider Analysis and Review File, 2011 to 2019. Participants included Medicare fee-for-service beneficiaries aged 66 years and older receiving MV for at least 96 hours in an intensive care unit (ie, patients at-risk for prolonged MV) and the subgroup also receiving a tracheostomy (ie, receiving prolonged MV). Data were analyzed from October 2022 to June 2023.
Admission to closure-affected hospitals, defined as those discharging at least 60% of patients receiving a tracheostomy to LTCHs that subsequently closed, vs control hospitals.
Upstream hospital care pattern outcomes were short-stay hospital do-not-resuscitate orders, palliative care delivery, tracheostomy placement, and discharge disposition. Patient outcomes included hospital length of stay, days alive and institution free within 90 days, spending per days alive within 90 days, and 90-day mortality.
Between 2011 and 2019, 99 454 patients receiving MV for at least 96 hours at 1261 hospitals were discharged to 459 LTCHs; 84 LTCHs closed. Difference-in-differences analysis included 8404 patients (mean age, 76.2 [7.2] years; 4419 [52.6%] men) admitted to 45 closure-affected hospitals and 45 matched-control hospitals. LTCH closure was associated with decreased LTCH transfer rates (difference, -5.1 [95% CI -8.2 to -2.0] percentage points) and decreased spending-per-days-alive (difference, -$8701.58 [95% CI, -$13 323.56 to -$4079.60]). In the subgroup of patients receiving a tracheostomy, there was additionally an increase in do-not-resuscitate rates (difference, 10.3 [95% CI, 4.2 to 16.3] percentage points) and transfer to skilled nursing facilities (difference, 10.0 [95% CI, 4.2 to 15.8] percentage points). There was no significant association of closure with 90-day mortality.
In this cohort study, LTCH closure was associated with changes in discharge patterns in patients receiving mechanical ventilation for at least 96 hours and advanced directive decisions in the subgroup receiving a tracheostomy, without change in mortality. Further studies are needed to understand how LTCH availability may be associated with other important outcomes, including functional outcomes and patient and family satisfaction.
重要性:长期急性护理医院(LTCH)是因严重呼吸衰竭而需要机械通气(MV)康复的患者进行急性后护理的常见场所。然而,联邦支付改革导致美国许多 LTCH 关闭,目前尚不清楚 LTCH 的关闭可能如何影响短期住院医院的上游护理模式和整体患者结局。
目的:评估 LTCH 关闭与短期住院医院护理模式和患者结局之间的关联。
设计、地点和参与者:这项回顾性、全国性、匹配队列研究使用差异中的差异分析比较了在 2012 年至 2018 年期间关闭的依赖 LTCH 的短期住院医院与对照医院的结局。数据来自医疗保险提供者分析和审查文件,时间范围为 2011 年至 2019 年。参与者包括年龄在 66 岁及以上、在重症监护病房(即有延长 MV 风险的患者)接受 MV 至少 96 小时且亚组患者还接受了气管切开术(即接受延长 MV 的患者)的 Medicare 收费服务受益人。数据分析于 2022 年 10 月至 2023 年 6 月进行。
暴露:入住受关闭影响的医院,定义为至少有 60%接受气管切开术的患者出院至随后关闭的 LTCH 的医院,与对照医院相比。
主要结局和测量:上游医院护理模式结局包括短期住院医院不复苏医嘱、提供姑息治疗、气管切开术安置和出院处置。患者结局包括住院时间、90 天内存活且无机构的天数、90 天内存活每天的支出以及 90 天死亡率。
结果:在 2011 年至 2019 年期间,1261 家医院的 99454 名接受 MV 至少 96 小时的患者出院至 459 家 LTCH;84 家 LTCH 关闭。差异中的差异分析包括 8404 名患者(平均年龄,76.2[7.2]岁;4419[52.6%]名男性)入住 45 家受关闭影响的医院和 45 家匹配的对照医院。LTCH 关闭与 LTCH 转院率降低(差异,-5.1[95%CI-8.2 至-2.0]个百分点)和每天存活支出减少(差异,-8701.58 美元[95%CI,-13323.56 美元至-4079.60 美元])相关。在接受气管切开术的亚组患者中,还观察到不复苏率增加(差异,10.3[95%CI,4.2 至 16.3]个百分点)和转至康复护理设施(差异,10.0[95%CI,4.2 至 15.8]个百分点)。关闭与 90 天死亡率之间无显著关联。
结论和相关性:在这项队列研究中,LTCH 关闭与接受至少 96 小时 MV 的患者出院模式变化以及接受气管切开术的亚组患者高级指导决策相关,而死亡率没有变化。需要进一步研究以了解 LTCH 的可用性如何与其他重要结局相关,包括功能结局和患者和家庭满意度。
