The purpose of the present study is to determine the differences in cost, complications, and mortality between knee arthroplasty (TKA) patients who stay the standard 3-4 nights in a hospital compared to patients who undergo an outpatient procedure, a shortened stay or an extended stay. TKA patients were identified in the Medicare 5% sample (1997-2009) and separated into the following groups: outpatient, 1-2 days, 3-4 days, or 5+ days inpatient. At two years, costs associated with the outpatient and the 1-2 day stay groups were $8527 and $1967 lower than the 3-4 day stay group, respectively. Out to 2 years, the outpatient and 1-2 day stay groups reported less pain and stiffness, respectively, though the 1-2 day group also had a higher risk for revision.
本研究的目的是确定在医院标准住院3 - 4晚的膝关节置换术（TKA）患者与接受门诊手术、缩短住院时间或延长住院时间的患者在成本、并发症和死亡率方面的差异。在医疗保险5%样本（1997 - 2009年）中识别出TKA患者，并将其分为以下几组：门诊患者、住院1 - 2天、住院3 - 4天或住院5天以上。两年时，门诊患者组和住院1 - 2天组的相关成本分别比住院3 - 4天组低8527美元和1967美元。到2年时，门诊患者组和住院1 - 2天组分别报告疼痛和僵硬程度较低，不过住院1 - 2天组的翻修风险也较高。
