RESUMO
BACKGROUND: Adult spinal deformity (ASD) significantly impacts the quality of life due to three-dimensional spinal abnormalities. Patient-reported outcome measures, such as the Patient-Reported Outcomes Measurement Information System (PROMIS-29), play a crucial role in assessing postoperative outcomes. This study aims to investigate trends in PROMIS-29 scores over 36 months in patients undergoing long-segment thoracolumbar fusion for ASD and provide insights into its long-term utility. METHODS: A retrospective study including 163 ASD patients undergoing long-segment thoracolumbar fusion was conducted. PROMIS-29 scores were collected at baseline and at postoperative (0-), 3-, 6-, 12-, 18-, 24-, 30-, and 36-month follow-ups. Statistical analyses was performed to assess significant score changes from baseline and in consecutive recordings. RESULTS: Significant improvements in all PROMIS-29 categories were observed at 36 months, with the greatest changes in pain intensity (-35.19%, P < 0.001), physical function (+29.13%, P < 0.001), and pain interference (-28.8%, P < 0.001). Between the 0 and 3 month mark, the greatest significant changes were recorded in pain intensity (-26.5%, P < 0.001), physical function (+24.3%, P < 0.001), and anxiety (-16.9%, P < 0.018). However, scores plateaued after the 3-month mark, with zero categories showing significant changes with subsequent consecutive recordings. CONCLUSIONS: PROMIS-29 scores demonstrated notable improvements in ASD patients particularly in pain intensity, pain interference, and physical function. However, scores plateaued beyond the 3-month mark, suggesting PROMIS-29's limited sensitivity to nuanced changes in long-term patient recovery. Future investigations exploring optimal combinations of patient reported outcome measures for comprehensive short- and long-term outcome assessments in ASD surgery would be beneficial.

BACKGROUND: Patients with adult spinal deformity (ASD) undergoing operative treatment may have varying degrees of improvement in patient-reported outcomes. The Oswestry Disability Index (ODI) assesses improvement in quality of life. We aim to measure longitudinal outcomes of ODI scores over 3 years to determine if early ODI scores predict late ODI scores and to analyze longitudinal changes in ODI scores. METHODS: Two hundred thirty-five patients above the age of 18 who underwent surgical correction of ASD at a single institution from 2016 to 2021 and completed ODI questionnaires at follow-up appointments met inclusion criteria. ODI scores were included from follow-up visits at 0 months (immediately postoperative) and within ±1 month of 3, 6, 12, 18, 24, 30, and 36 months. Percent change in ODI from 0 months was calculated, and unpaired t tests were conducted. RESULTS: ODI scores increased by 8.8% immediately postoperatively, and the percent change from preoperative ODI scores at each subsequent visit were as follows: -11.1% at 3 months, -21.4% at 6 months, -25.4% at 12 months, -28% at 18 months, -31.3% at 24 months, -25.7% at 30 months, and -36.5% at 36 months. ODI scores at each follow-up visit showed significant improvement from baseline (P < 0.001). There was an improvement in scores from 3 to 6 months (P = 0.04), but no significant difference in 6-month interval visits following 6 months. CONCLUSIONS: Our results demonstrate a significant and sustained improvement in ODI scores over 3 years following surgical correction of ASD. ODI scores were stable after 6 months, indicating that ODI scores at 6 months may be predictive of scores out to 3 years postoperatively. Examining individual components of ODI sub-scores and comparing ODI results to other PROMs are critical to better assess long-term outcomes in ASD.

BACKGROUND: Adult spinal deformity (ASD) is becoming increasingly common in aging populations. Patient-reported outcome measures (PROMs) are self-reported patient surveys administered pre- and postoperatively that provide insight into patient improvement. We aim to compare 3 of the most utilized PROMs: PROMIS-29, Oswestry Disability Index (ODI), and Visual Analogue Scale (VAS), to investigate whether they provide unique and independent assessments of patient outcomes when assessed longitudinally. METHODS: We retrospectively reviewed a database of ASD at UT Southwestern Medical Center between 2016 and 2021. Adult patients (>18 years old) were included if they underwent long-segment (>4 levels) thoracolumbar fusion. PROMIS-29, ODI, and VAS scores were collected preoperatively and at 3-, 6-, 12-, 18-, 24-, 30-, and 36-month follow-ups. Scores were recorded ±1 month of the time points. Pearson correlation coefficients for each PROM were then calculated in a pairwise fashion. RESULTS: A total of 163 patients were included in our analysis. ODI and VAS showed significant covariance, with VAS Neck and VAS Back having Pearson coefficients of 0.95 and 0.94, respectively. ODI and PROMIS-29 also showed significant covariance, with Physical Function and ODI showing a Pearson coefficient of 0.95. PROMIS-29 and VAS demonstrated less correlation regarding Pain and Physical Function; however, they showed a significantly high Pearson coefficient when comparing VAS Back with PROMIS-29 Sleep and Pain Intensity (r = 0.97 and r = 0.96, respectively). CONCLUSIONS: All 3 PROMs demonstrated significant correlation over 36 months, indicating that simultaneous administration of each during follow-up is redundant. The measure that provided the least unique information was ODI, as both VAS and PROMIS-29 demonstrated similar progression and assessed additional metrics. PROMIS-29 provided the same information as VAS and ODI, with extra facets of patient-reported outcomes, indicating that it may be a more comprehensive measure of longitudinal patient improvement.
