To assess the effects of recall bias on prospectively collected patient-reported outcome (PRO) measures after lumbar laminectomy by analyzing correlations between PROs and step counts in measurement windows preceding PRO measurement.
Responses to the 12-item Short Form Health Survey (SF-12) and the Oswestry Disability Index (ODI) were collected postoperatively from 22 patients. Accelerometers recorded daily step counts. Median and maximum step counts were calculated for windows (1 day, 3 days, 1 week, and 2 weeks) preceding PRO measurement. Spearman rank correlation coefficients between PROs and step counts were calculated.
Median and maximum step counts from 1- and 2-week windows more consistently correlated with SF-12 Physical Component Scores scores than 1- and 3-day windows over the postoperative period. Median steps from 1-, 2-week, and 3-day windows correlated more with ODI scores than the 1-day window. Maximum steps from 1- and 2-week windows correlated more than 1- and 3-day windows.
PROs had higher concordance with step counts from the 1 week and 2 weeks before PRO measurement than the 1 day and 3 days prior. We therefore conclude that SF-12 and ODI are not markedly affected by recall bias because scores are not skewed by the events of the days immediately preceding measurement.
通过分析患者报告结局（PRO）测量前测量窗口中PRO与步数之间的相关性，评估回忆偏倚对腰椎椎板切除术后前瞻性收集的PRO测量指标的影响。
术后收集了22例患者对12项简短健康调查问卷（SF-12）和奥斯威斯利功能障碍指数（ODI）的回答。加速度计记录每日步数。计算PRO测量前各窗口（1天、3天、1周和2周）的步数中位数和最大值。计算PRO与步数之间的Spearman等级相关系数。
在术后期间，与1天和3天的窗口相比，1周和2周窗口的步数中位数和最大值与SF-12身体成分得分的相关性更一致。与1天的窗口相比，1周、2周和3天窗口的步数中位数与ODI得分的相关性更强。1周和2周窗口的最大步数相关性高于1天和3天的窗口。
与测量前1天和3天相比，PRO与测量前1周和2周的步数具有更高的一致性。因此，我们得出结论，SF-12和ODI不受回忆偏倚的显著影响，因为得分不会因测量前几天的事件而产生偏差。
