Physical function evaluated by Patient-Reported Outcomes Measurement Information System (PROMIS PF) instrument has been validated through the short-term postsurgical period in spine surgery patients. Evidence for long-term efficacy of PROMIS PF is lacking in lumbar decompression (LD) patients. The objective of this study was to evaluate correlations between PROMIS PF and legacy patient-reported outcome measures for patients undergoing LD.
Consecutive primary or revision, single-level or multilevel LD surgeries were retrospectively reviewed from May 2015 to September 2017. Patients lacking preoperative or 2-year PROMIS PF scores were excluded. Demographics, baseline pathology, and perioperative characteristics were collected, and descriptive statistics performed. Visual Analogue Scale (VAS) back and leg, Oswestry Disability Index (ODI), 12-Item Short Form (SF-12) Physical Composite Score (PCS), and PROMIS PF were collected at preoperative and postoperative timepoints and evaluated for improvement from baseline values. Correlations between PROMIS PF and VAS back, VAS leg, SF-12 PCS, and ODI were calculated and categorized according to the strength of relationship.
Ninety-two patients were included in this study with 58.7% of LDs performed at the single level. All patient-reported outcome measures demonstrated significant improvement from baseline values at all assessment timepoints (all P < 0.001). Apart from preoperative VAS back and VAS leg, PROMIS PF demonstrated a significant and strong correlation with VAS back, VAS leg, ODI, and SF-12 PCS at all timepoints (all P < 0.001).
PROMIS PF demonstrated a strong correlation with pain, disability, and PF outcome measures throughout the postoperative period out to 2 years after LD. Our study provides longitudinal evidence that the PROMIS PF instrument is a valid measure for PF for patients undergoing LD.
通过患者报告的结果测量信息系统（PROMIS PF）仪器评估的身体功能已在脊柱外科患者的短期术后期间得到验证。在腰椎减压术（LD）患者中，缺乏 PROMIS PF 的长期疗效证据。本研究的目的是评估 PROMIS PF 与传统患者报告的结果测量在接受 LD 的患者之间的相关性。
回顾性分析 2015 年 5 月至 2017 年 9 月期间连续进行的原发性或复发性、单节段或多节段 LD 手术。排除术前或 2 年 PROMIS PF 评分缺失的患者。收集患者的人口统计学、基线病理和围手术期特征，并进行描述性统计。收集术前和术后时间点的视觉模拟量表（VAS）背部和腿部、Oswestry 残疾指数（ODI）、12 项简短形式（SF-12）物理综合评分（PCS）和 PROMIS PF，并根据基线值评估改善情况。计算 PROMIS PF 与 VAS 背部、VAS 腿部、SF-12 PCS 和 ODI 之间的相关性，并根据关系的强度进行分类。
本研究共纳入 92 例患者，其中 58.7%的 LD 为单节段。所有患者报告的结果测量在所有评估时间点均显示出与基线值相比的显著改善（均 P < 0.001）。除了术前 VAS 背部和 VAS 腿部外，PROMIS PF 在所有时间点均与 VAS 背部、VAS 腿部、ODI 和 SF-12 PCS 呈显著且强相关（均 P < 0.001）。
PROMIS PF 在 LD 后至 2 年的整个术后期间与疼痛、残疾和 PF 结果测量具有很强的相关性。我们的研究提供了纵向证据，表明 PROMIS PF 仪器是 LD 患者 PF 的有效测量工具。
