“…A few studies have developed crosswalk tables to link various PROMs for orthopaedic patients. [32][33][34][35] In this study, we linked the KOOS-PS instrument with the PROMIS-PF 10a: although the KOOS-PS is a joint-specific measure and the PROMIS-PF 10a is a universal measure, both instruments mainly measure respondents' ability to function in everyday life.…”

Introduction:The Knee Injury and Osteoarthritis Outcome Score-Physical Function Short-form and the Patient-Reported Outcomes Measurement Information System Physical Function are widely used patient-reported outcome measures in orthopaedic practice and research. It would be helpful for clinicians and researchers to compare scores obtained on one instrument with those collected on another. To achieve this goal, this study conducted a linking analysis and computed a crosswalk table between these two scales. Data: The data of this study were collected as part of the clinical care of total knee arthroplasty patients in a large urban and suburban health system. The sample was a mix of responses from nonsurgical (no surgery performed), preoperative (before surgical intervention), and postoperative (after surgical intervention) groups. Methods: This study applied five linking methods: the item response theory (IRT)-based linking methods including fixed-parameter calibration, separate-parameter calibration with Stocking-Lord constants, and calibrated projection; and the equipercentile methods with log-linear smoothing and nonsmoothing approaches. Before conducting the linking analysis, we checked the linking assumptions including the similar content of the two scales, the unidimensionality of the combined scales, and the population invariance. The results of the five linking methods were evaluated by mean difference, SD, root-mean-squared deviation, intraclass correlation coefficient of the observed T scores and the crosswalkderived T scores. Results: The linking assumptions were all met. T scores generated from the Stocking-Lord crosswalk had the smallest mean difference (= 20.03) and relatively small SD (= 4.91) and root-mean-squared deviation (= 4.91) among the five linking methods. We validated this crosswalk in a larger sample with the nonsurgical, preoperative, and postoperative groups and in an external sample.

“…These crosswalks add to the literature linking anatomic-specific and generic (eg, PROMIS) measures of health status. 27–29 Our findings are strengthened by a large sample of unique patients who each completed both assessments. This single-sample approach allowed us to compare observed and linked scores based on the linking approach to determine accuracy.…”

Introduction: Linking scores on patient-reported outcome measures can enable data aggregation for research, clinical care, and quality. We aimed to link scores on the Hip Disability and Osteoarthritis Outcome Score-Physical Function Short Form (HOOS-PS) and the Patientreported Outcomes Measurement Information System Physical Function (PROMIS PF). Methods: A retrospective study was conducted from 2017 to 2020 evaluating patients with hip osteoarthritis who received routine clinical care from an orthopaedic surgeon. Our sample included 3,382 unique patients with 7,369 pairs of HOOS-PS and PROMIS PF measures completed at a single nonsurgical, preoperative, or postoperative time point. We included one randomly selected time point of scores for each patient in our linking analysis sample. We compared the accuracy of linking using four methods, including equipercentile and item response theory-based approaches. Results: PROMIS PF and HOOS-PS scores were strongly correlated (r = 20.827 for raw HOOS-PS scores and r = 0.820 for summary HOOS-PS scores). The assumptions were met for equipercentile and item response theory approaches to linking. We selected the item response theory-based Stocking-Lord approach as the optimal crosswalk and estimated item parameters for the HOOS-PS items on the PROMIS metric. A sensitivity analysis demonstrated overall robustness of the crosswalk estimates in nonsurgical, preoperative, and postoperative patients. Conclusion: These crosswalks can be used to convert scores between HOOS-PS and PROMIS PF metric at the group level, which can be valuable for data aggregation. Conversion of individual patient-level data is not recommended secondary to increased risk of error.

“…ODI scores strongly correlated with PROMIS PF and PIf scores at baseline (r = −0.72 to 0.71) and at up to 24 months (r = −0.89 to 0.88) after lumbar surgery 33 . ODI correlates well enough with PROMIS PIf and PROMIS-29 which has allowed the formulation of predictive equations for the ODI derived from PROMIS 28,34 .…”

Objective:Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to address certain shortcomings of traditional, or legacy patient-reported outcome measures (PROMs). Because the use of PROMIS across orthopedic populations continues to increase, the purpose of this study was to provide a comprehensive overview of the use and validation of PROMIS in spine surgery.Methods:PubMed and Google Scholar were searched for relevant articles reporting on the use and validation of PROMIS in spine surgery. The PROMIS formats and individual domains used by investigators were noted. Additionally, psychometric properties reported in validation studies were evaluated.Results:Both individual studies and systematic reviews have demonstrated the convergent validity of PROMIS domains, reporting moderate-to-strong correlations with legacy measures in a variety of spine patient populations. Across spine surgery patient populations, PROMIS instruments are consistently efficient, demonstrating decreased question burden compared with legacy PROMs. PROMIS domains overall exhibit responsiveness comparable with legacy measures, and the normalization of PROMIS scores to a general population allows for broad coverage, resulting in acceptable floor and ceiling effects. Despite the many strengths of PROMIS, there remain some populations where PROMIS is not suited to be used in isolation.Conclusions:PROMIS is widely used as an outcome measure in spine surgery and has been validated in a range of patient populations. Although PROMIS domains cannot fully replace legacy measures in spine patients, they can be used in certain settings to provide an efficient and psychometrically sound PROM.
