Loss to follow-up in registry studies is a problem due to potential selection bias. There is no consensus on the effect of response rate. The aim of this study was to compare patient-reported outcome measures (PROMs) between responders and initial non-responders (INR) in a hip arthroscopy registry and to examine whether demographics affect the response rate. Data from hip arthroscopies performed at two centres in Gothenburg were collected and the patients were followed up with PROMs. The follow-up was a minimum of 2 years after surgery. All 536 patients who underwent primary hip arthroscopies during 2015 and 2016 and had recorded pre-operative PROMs were included. A total of 396 patients completed the follow-up and were labelled 'Responders' (R) and 107 patients responded after reminders were sent and labelled 'Initial non-responders' (INR). The mean time of follow-up was 24.7 ± 2.9 and 42.5 ± 7.0 months for the R- and INR-group, respectively. There were no differences between the two groups at the follow-up for the Copenhagen Hip and Groin Outcome Score, European Quality of life 5 dimensions questionnaire, EQ-VAS, International Hip Outcome Tool or a visual analogue scale for hip function. A larger proportion of R was satisfied after hip arthroscopy compared with INR (86% versus 70%, = 0.0003). INR were younger than responders (31.5 ± 12.5 versus 35.6 ± 12.7 years of age). The conclusion of the study was that there were no differences between R and INR at the follow-up across the PROMs except patient satisfaction, where responders were more satisfied.
在登记研究中，失访是一个问题，因为可能存在选择偏倚。关于应答率的影响尚无共识。本研究的目的是比较髋关节镜登记研究中应答者与初始无应答者（INR）之间患者报告的结局指标（PROMs），并研究人口统计学因素是否会影响应答率。收集了在哥德堡两个中心进行的髋关节镜检查数据，并使用PROMs对患者进行随访。随访时间至少为术后2年。纳入了2015年至2016年期间接受初次髋关节镜检查且术前记录了PROMs的所有536例患者。共有396例患者完成随访，被标记为“应答者”（R），107例患者在收到提醒后做出应答，被标记为“初始无应答者”（INR）。R组和INR组的平均随访时间分别为24.7±2.9个月和42.5±7.0个月。在随访时，两组在哥本哈根髋关节和腹股沟结局评分、欧洲生活质量5维度问卷、EQ-VAS、国际髋关节结局工具或髋关节功能视觉模拟量表方面没有差异。与INR相比，髋关节镜检查后R组中有更大比例的患者感到满意（86%对70%，=0.0003）。INR比应答者年轻（年龄分别为31.5±12.5岁和35.6±12.7岁）。该研究的结论是，除了患者满意度方面应答者更满意外，随访时R组和INR组在各项PROMs上没有差异。
