OBJECTIVES To determine the factors associated with acute hospital discharge to the three most common post-acute settings following TKA (Total Knee Arthroplasty): inpatient rehabilitation facilities (IRFs), skilled nursing facilities (SNFs), and directly back to the community. DESIGN Retrospective cohort study. SETTING Acute care hospitals submitting claims to Medicare. PARTICIPANTS National cohort (N=1,189,286) of 100% Medicare Part A data files from 2009-2011. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Observed rates and adjusted odds of discharge to the three main post-acute settings based on the clinical and facility level variables: amount of comorbidity, bilateral procedures and facility TKA volume. RESULTS Using IRF discharge as the reference, patients who received a bilateral procedure had lower odds of both SNF and community discharge; patients with more comorbidity had lower odds for community discharge and higher odds for SNF discharge; and patients who received their TKA from hospitals with lower TKA volumes had lower odds of SNF and community discharge. CONCLUSIONS Clinical populations within Medicare beneficiaries may systematically vary across the three most common discharge settings following TKA. This information may be helpful for a better understanding on which patient or clinical factors influence PAC settings following TKA. Additional research including functional status, living situation, regional variation, and social support systems would be beneficial.

医疗保险患者全膝关节置换术后出院情况的预测因素

目的 确定与 TKA(全膝关节置换术)后三种最常见的急性后环境急性出院相关的因素:住院康复设施 (IRF)、专业护理设施 (SNF) 和直​​接返回社区。设计 回顾性队列研究。设置 急症护理医院向 Medicare 提交索赔。参与者 2009-2011 年 100% 医疗保险 A 部分数据文件的全国队列 (N=1,189,286)。干预 不适用。主要结局指标 根据临床和机构层面的变量:合并症数量、双侧手术和机构 TKA 量,观察到的三个主要急性期后设置的观察率和调整后的出院几率。结果以IRF放电为参考,接受双侧手术的患者 SNF 和社区出院的几率较低;合并症较多的患者社区出院的几率较低,而 SNF 出院的几率较高;从 TKA 数量较少的医院接受 TKA 的患者 SNF 和社区出院的几率较低。结论 在 TKA 后三种最常见的出院环境中,Medicare 受益人的临床人群可能存在系统性差异。此信息可能有助于更好地了解哪些患者或临床因素会影响 TKA 后的 PAC 设置。包括功能状态、生活状况、区域差异和社会支持系统在内的其他研究将是有益的。从 TKA 数量较少的医院接受 TKA 的患者 SNF 和社区出院的几率较低。结论 在 TKA 后三种最常见的出院环境中,Medicare 受益人的临床人群可能存在系统性差异。此信息可能有助于更好地了解哪些患者或临床因素会影响 TKA 后的 PAC 设置。包括功能状态、生活状况、区域差异和社会支持系统在内的其他研究将是有益的。从 TKA 数量较少的医院接受 TKA 的患者 SNF 和社区出院的几率较低。结论 在 TKA 后三种最常见的出院环境中,Medicare 受益人的临床人群可能存在系统性差异。此信息可能有助于更好地了解哪些患者或临床因素会影响 TKA 后的 PAC 设置。包括功能状态、生活状况、区域差异和社会支持系统在内的其他研究将是有益的。此信息可能有助于更好地了解哪些患者或临床因素会影响 TKA 后的 PAC 设置。包括功能状态、生活状况、区域差异和社会支持系统在内的其他研究将是有益的。此信息可能有助于更好地了解哪些患者或临床因素会影响 TKA 后的 PAC 设置。包括功能状态、生活状况、区域差异和社会支持系统在内的其他研究将是有益的。
