Purpose - The primary objective in this study was to describe the patient-reported outcome measures (PROMs) of total hip replacement (THR) patients 6 years after index surgery. Second, we sought to analyze how the preoperative, 1- and 6-year outcomes were associated. Patients and methods - By assessing the Swedish Hip Arthroplasty Register (SHAR), 15,755 patients with complete follow-up were included in the study group. 1-year and 6-year response rates were 93% and 87%. PROMs used by the SHAR include the EQ-5D instrument, and 2 modified visual analogue scales, 1 for pain and 1 for satisfaction. We used a multivariable linear regression model to examine the relationship between preoperative, 1-year, and 6-year outcome. Results - On average, patient-reported outcomes 6 years after THR were satisfactory. Though there was some deterioration in all mean 6-year PROMs, the patient-reported outcome after 6 years strongly resembled that of the 1-year results. The 1-year follow-up was the strongest factor associated with the 6-year results. Interpretation - There is little deterioration in patient-reported outcomes 6 years after THR compared with the 1-year results. Although the 1-year follow-up was the strongest predictor of the 6-year results it could not alone explain the results, thus supporting the utility of the 6-year follow-up in THR patients.
目的——本研究的主要目的是描述全髋关节置换术（THR）患者在初次手术后6年的患者报告结局指标（PROMs）。其次，我们试图分析术前、1年和6年的结局是如何关联的。患者与方法——通过评估瑞典髋关节置换登记处（SHAR），15755名有完整随访记录的患者被纳入研究组。1年和6年的回复率分别为93%和87%。SHAR使用的PROMs包括EQ-5D工具以及2个改良的视觉模拟量表，1个用于疼痛，1个用于满意度。我们使用多变量线性回归模型来检验术前、1年和6年结局之间的关系。结果——平均而言，THR术后6年患者报告的结局令人满意。尽管所有6年PROMs的均值都有一定程度的恶化，但6年后患者报告的结局与1年时的结果非常相似。1年随访是与6年结果关联最强的因素。解读——与1年结果相比，THR术后6年患者报告的结局几乎没有恶化。虽然1年随访是6年结果的最强预测因素，但它并不能单独解释这些结果，因此支持对THR患者进行6年随访的实用性。
