BACKGROUND
Many PROMs used for evaluation of ankle osteoarthritis are not validated for this purpose. We hypothesize that frequently used PROMs have an early ceiling or floor effect.
METHODS
We prospectively collected data from patients with ankle osteoarthritis between 2011 and 2013. At baseline visit patients completed the Foot and Ankle Outcome Score, the Ankle Osteoarthritis Score, the American Orthopaedic Foot and Ankle Society scale, a visual analogue scale for pain and quality of life. Outcomes were analyzed for floor or ceiling effects.
RESULTS
197 patients were included in the study. A floor effect was present for the AOFAS and VAS for pain in all groups. Floor and ceiling effect are absent for the FAOS outcome measure for all groups.
CONCLUSIONS
Physicians should be aware of floor or ceiling effects when evaluating treatment using patient reported outcome measures. The FAOS outcome measure lacks early ceiling or floor effects.
背景
许多用于评估踝关节骨关节炎的患者报告结局测量工具（PROMs）并未针对该目的进行验证。我们假设常用的PROMs存在早期天花板效应或地板效应。
方法
我们前瞻性地收集了2011年至2013年间踝关节骨关节炎患者的数据。在基线访视时，患者完成了足踝结局评分、踝关节骨关节炎评分、美国矫形足踝协会量表、疼痛视觉模拟量表和生活质量量表。对结局进行了地板效应或天花板效应分析。
结果
197名患者纳入研究。所有组中，美国矫形足踝协会量表（AOFAS）和疼痛视觉模拟量表（VAS）均存在地板效应。所有组的足踝功能评分（FAOS）结局测量均不存在地板效应和天花板效应。
结论
在使用患者报告结局测量评估治疗时，医生应意识到地板效应或天花板效应。足踝功能评分结局测量不存在早期天花板效应或地板效应。
