Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE To examine the validity of the Oswestry Disability Index (ODI) in patients with adult spinal deformity (ASD) treated with surgery. BACKGROUND The ODI is a patient-reported outcome measure of low back pain and disability. Although nearly ubiquitous in ASD research, the measure has not been validated in this patient population. PATIENTS AND METHODS A registry of patients with ASD was queried for baseline and 1-year PROM data, including the ODI, the Scoliosis Research Society-22r (SRS-22r), and the Patient Reported Outcomes Measurement Information System-Pain Interference (PI) and Physical Function (PF) CATs. Internal reliability was assessed with Cronbach alpha, where values ≥0.7 are considered reliable. Validity was assessed with Spearman correlation coefficients calculated for the ODI against validated Patient-Reported Outcomes Measurement Information System (PROMIS)-PI and PF, and legacy measures SRS-Pain and SRS-Activity. Responsiveness to change was measured with the adjusted effect size. RESULTS A total of 325 patients were enrolled, with 208 completing baseline and 1-year patient-reported outcome measures. The majority (149, 72%) were females and White (193, 93%), median Charlson Comorbidity Index 0 (interquartile range: 0-2). The majority of cases included sagittal plane deformity [mean T1PA: 24.2° (13.9)]. Cronbach alpha showed excellent internal reliability (baseline = 0.89, 1 yr = 0.90). ODI was valid, with strong correlations between PROMIS-PI, PROMIS-PF, SRS-Pain, and SRS-Activity at baseline and 1-year follow-up. All measures were responsive to change, with the ODI showing greater responsiveness than PROMIS-PI, PROMIS-PF, and SRS-Activity. CONCLUSIONS The ODI is a valid measure of disability as measured by pain and function in patients with ASD. It is responsive to change in a manner not different from validated PROMIS-CAT or the SRS-22r legacy measure. It is multidimensional, however, as it assesses both pain and function simultaneously. It does not measure disability related to self-image and may not account for all disease-related disability in patients with ASD.

Abstract
BACKGROUND We sought to assess the concurrent validity of select Patient Reported Outcomes Measurement Information System (PROMIS) domains and Limb Deformity-Scoliosis Research Society (LD-SRS) scores. METHODS We prospectively administered PROMIS-25 (including anxiety, depression, fatigue, pain interference, peer relationships, and physical function) and LD-SRS questionnaires to 46 consecutive pediatric patients with lower limb differences, presenting to a single surgeon for reconstruction. Concurrent validity between various subdomains of the 2 outcome measures was assessed through Pearson's correlation, with significance defined as P <0.05. The strength of correlation was interpreted by Evans criteria: absolute r value <0.20 indicating very weak correlation; 0.20 to 0.39, weak; 0.40 to 0.59, moderate; 0.60 to 0.79, strong; and 0.8 or greater indicating very strong correlation. RESULTS The LD-SRS Pain, Function, and Mental Health domains most strongly correlated with the PROMIS pain interference (r=-0.79, P<0.001), physical function (r=0.74, P<0.001), and anxiety (r=-0.68, P <0.001) domains, respectively. In addition, LD-SRS pain strongly correlated with PROMIS physical function (r=0.61, P<0.001) and LD-SRS function with PROMIS pain interference (r=-0.72, P<0.001). All PROMIS domains significantly correlated with total LD-SRS scores. PROMIS pain interference (r=-0.79, P <0.001), physical function (r=0.67, P <0.001), and fatigue (r=-0.60, P <0.001) domains demonstrated the strongest correlations with the total LD-SRS score. CONCLUSIONS The significant concurrent validity between LD-SRS and multiple PROMIS domains suggests considerable overlap, and perhaps redundancy, between these 2 outcome measures. Given the high degree of concordance and the advantage of computer adaptive testing (CAT) in mitigating administrative burden and survey fatigue, along with the ability to compare outcomes across a wider group of children with a variety of underlying diagnoses, select PROMIS domains may be a viable alternative to LD-SRS score for assessing patient-reported outcomes when treating pediatric patients with lower limb deformities. A larger, multi-center study including pediatric patients with lower limb differences from a diverse background, including age, etiology, native language, and ethnicity, would be helpful to externally validate our findings. LEVEL OF EVIDENCE Level-I.

Abstract
STUDY DESIGN Literature review. OBJECTIVE The aim of this review is to summarize recent literature on adult spinal deformity (ASD) treatment failure as well as prevention strategies for these failure modes. SUMMARY OF BACKGROUND DATA There is substantial evidence that ASD surgery can provide significant clinical benefits to patients. The volume of ASD surgery is increasing, and significantly more complex procedures are being performed, especially in the aging population with multiple comorbidities. Although there is potential for significant improvements in pain and disability with ASD surgery, these procedures continue to be associated with major complications and even outright failure. METHODS A systematic search of the PubMed database was performed for articles relevant to failure after ASD surgery. Institutional review board approval was not needed. RESULTS Failure and the potential need for revision surgery generally fall into 1 of 4 well-defined phenotypes: clinical failure, radiographic failure, the need for reoperation, and lack of cost-effectiveness. Revision surgery rates remain relatively high, challenging the overall cost-effectiveness of these procedures. CONCLUSION By consolidating the key evidence regarding failure, further research and innovation may be stimulated with the goal of significantly improving the safety and cost-effectiveness of ASD surgery.

Patient-Reported Outcomes Measurement Information System physical function instruments compare favorably to legacy patient-reported outcome measures in spine patients: a systematic review of the literature. Spine J 2022; 22:646-659. [PMID: 34699997 DOI: 10.1016/j.spinee.2021.10.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 10/13/2021] [Accepted: 10/13/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Preliminary evidence has suggested favorable correlation between National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS) assessments and traditional ("legacy") patient reported outcome measures (PROMs) in spine surgery. There has been a significant increase in PROMIS research with regards to spinal conditions. PURPOSE The purpose of this systematic review is to provide an assessment of PROMIS Physical Function (PF) measures in this patient population. STUDY DESIGN/SETTING Systematic review. METHODS A systematic search of the PubMed/MEDLINE and Embase databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify published articles that referenced the various PROMIS PF measures. Two authors independently reviewed selected studies. The search returned 1,060 studies, 124 of which were selected for independent review by two authors. Of these, 37 were selected for inclusion. Mixed linear models were performed to assess for differences between legacy PROMs and PROMIS measures. RESULTS The combined sample size of all included studies yielded 10,296 total patients. Overall, PROMIS Physical Function (PF) measures demonstrated strong correlations with legacy PROMs when evaluating spine patients (weighted Pearson correlation, 0.589, standard error [SE]=0.023; weighted Spearman correlation, 0.702, SE=0.028). PROMIS questionnaires had significantly fewer questions than did legacy PROMs (4.2±0.30 vs. 9.53±0.82, p=.015). In spine studies, the PROMIS PF forms were completed in significantly less time than legacy PROMs (48.1±2.9 vs. 174.7±12.6 seconds, p<.001). The differences for the reliability measures and the floor and ceiling effects were not significant. CONCLUSIONS Patient-Reported Outcomes Measurement Information System PF forms compare favorably with legacy PROMs with regard to correlations, ease of use, and quality criteria in the field of spine surgery. PROMIS PF scores correlate strongly with commonly used legacy PROMs, particularly in spine patients. Patient-Reported Outcomes Measurement Information System PF forms can be administered efficiently and to a broad patient population while remaining highly reliable.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The aim of this study was to determine whether Patient-reported Outcomes Measurement Information System (PROMIS) Pediatric Domain scores can be accurately and reliably predicted from legacy patient-reported outcome measures (PROMs) for use in adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA Previous efforts have been made to develop translational models between PROMIS domains and legacy PROMs in adult spinal deformity, but translational models for pediatric and adolescent patients with spinal deformity have not yet been developed. METHODS Scores were retrospectively collected on pediatric patients 8-17 years old who were diagnosed with spinal asymmetry or scoliosis for the following PROMs: Scoliosis Research Society-22r (SRS-22r), Trunk Appearance Perception Scale (TAPS), Hospital for Special Surgery Functional Activity Brief Scale (HSS Pedi-FABS), and PROMIS Pediatric Domains: Pain Interference, Mobility, Physical Stress Experiences, Psychological Stress Experiences, and Physical Activity. Pearson correlations were calculated between legacy and PROMIS scores. In the derivation cohort, PROMIS domains were modeled from SRS-22r or HSS Pedi-FABS using linear regression. These equations were used to predict PROMIS scores in the test cohort to determine the reliability of the translation model. RESULTS A total of 1171 patients (68% female) with a mean age of 13.4 ± 2.3 years were included in the final analyses. PROMIS Pain Interference was dependent on SRS-22r domains Pain, Function, Mental Health, and Management Satisfaction, PROMIS Mobility was dependent on SRS-22r Pain, Function, Mental Health, and Self-Image, PROMIS Physical Stress Experiences and Psychological Stress Experiences were dependent on SRS-22r Pain, Mental Health, and Management Satisfaction, and PROMIS Physical Activity was dependent on HSS Pedi-FABS. (P < 0.05 for all). In the test cohort, all developed models for PROMIS domains demonstrated strong correlations between estimated and actual scores (r = 0.63-0.75). CONCLUSION All of the evaluated PROMIS domains (Pain Interference, Mobility, Physical Stress Experiences, Psychological Stress Experiences, Physical Activity) were reliably translated directly from these legacy scores for pediatric and adolescent patients with spinal deformity.Level of Evidence: 3.

Abstract
OBJECTIVE The aim of this study was to determine the concurrent validity, discriminant ability, and responsiveness of the Patient-Reported Outcomes Measurement Information System (PROMIS) in adult spinal deformity (ASD) and to calculate minimal clinically important differences (MCIDs) for PROMIS scores. METHODS The authors used data obtained in 186 surgical patients with ASD. Concurrent validity was determined through correlations between preoperative PROMIS scores and legacy measure scores. PROMIS discriminant ability between disease severity groups was determined using the preoperative Oswestry Disability Index (ODI) value as the anchor. Responsiveness was determined through distribution- and anchor-based methods, using preoperative to postoperative changes in PROMIS scores. MCIDs were estimated on the basis of the responsiveness analysis. RESULTS The authors found strong correlations between PROMIS Pain Interference and ODI and the Scoliosis Research Society 22-item questionnaire Pain component; PROMIS Physical Function and ODI; PROMIS Anxiety and Depression domains and the 12-Item Short Form Health Survey version 2, Physical and Mental Components, Scoliosis Research Society 22-item questionnaire Mental Health component (anxiety only), 9-Item Patient Health Questionnaire (anxiety only), and 7-Item Generalized Anxiety Disorder questionnaire; PROMIS Fatigue and 9-Item Patient Health Questionnaire; and PROMIS Satisfaction with Participation in Social Roles (i.e., Social Satisfaction) and ODI. PROMIS discriminated between disease severity groups in all domains except between none/mild and moderate Anxiety, with mean differences ranging from 3.7 to 8.4 points. PROMIS showed strong responsiveness in Pain Interference; moderate responsiveness in Physical Function and Social Satisfaction; and low responsiveness in Anxiety, Depression, Fatigue, and Sleep Disturbance. Final PROMIS MCIDs were as follows: -6.3 for Anxiety, -4.4 for Depression, -4.6 for Fatigue, -5.0 for Pain Interference, 4.2 for Physical Function, 5.7 for Social Satisfaction, and -3.5 for Sleep Disturbance. CONCLUSIONS PROMIS is a valid assessment of patient health, can discriminate between disease severity levels, and shows responsiveness to changes after ASD surgery. The MCIDs provided herein may help clinicians interpret postoperative changes in PROMIS scores, taking into account the fact that they are pending external validation.

Longitudinal Evaluation of Patient-Reported Outcomes Measurement Information System for Back and Leg Pain in Minimally Invasive Transforaminal Lumbar Interbody Fusion. Neurospine 2020; 17:862-870. [PMID: 33401864 PMCID: PMC7788402 DOI: 10.14245/ns.1938398.199] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2018] [Accepted: 09/30/2018] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE While visual analogue score (VAS) metrics are among the most universally adopted patient-reported outcome measures (PROMs), there is limited research on the influence of back and leg pain on the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) scores. Here we assess the association of VAS back and VAS leg scores with PROMIS PF in the setting of minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). Secondarily, we determine if PROMIS PF is more influenced by back or leg pain. METHODS A prospective surgical registry was reviewed from May 2015 to November 2018. Inclusion criteria were primary, single-level MIS TLIFs. We excluded multilevel procedures and patients without preoperative PROMs. Pre- and postoperative PROMIS PF, VAS back, and VAS leg scores were recorded at 6 weeks, 12 weeks, 6 months, and 1 year. A Pearson correlation evaluated PROMIS PF association with VAS back and VAS leg scores. A Fisher z-test compared correlations. Linear regression evaluated PROMIS with VAS back and VAS leg scores. RESULTS Our cohort was comprised of 146 subjects. 40.4% were female and the average age of 51 years. VAS back demonstrated a stronger correlation than VAS leg with PROMIS PF at all timepoints. PROMIS PF scores were negatively associated with both VAS back and VAS leg at all timepoints. Fisher z-test revealed VAS back to have a stronger correlation with PROMIS PF (p = 0.025) than VAS leg. CONCLUSION In the setting of MIS TLIF, physical function as evaluated by PROMIS PF, had a stronger correlation with VAS back than VAS leg at 6 months. This suggests that postoperative PROMIS PF scores may be more influenced by back pain than with leg pain.
