Psychometrics of the Patient-Reported Outcomes Measurement Information System Physical Function instrument administered by computerized adaptive testing and the Disabilities of Arm, Shoulder and Hand in the orthopedic elbow patient population

Developing Linkages Between PROMIS Physical Function CAT and QuickDASH Scores in Hand Surgery: A Crosswalk Study

BACKGROUND

There is no standardization within hand and upper-extremity surgery regarding which patient-reported outcome measures (PROMs) are collected and reported. This limits the ability to compare or combine cohorts that utilize different PROMs. The aim of this study was to develop a linkage model for the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand) and PROMIS PF CAT (Patient-Reported Outcomes Measurement Information System Physical Function computerized adaptive testing) instruments to allow interconversion between these PROMs in a hand surgery population.

METHODS

A retrospective review was conducted to identify adults (≥18 years old) who had completed the QuickDASH and PROMIS PF CAT instruments at the same clinical encounter. Patients with shoulder pathology were excluded. The linear relationship between scores was evaluated with use of the Pearson correlation coefficient. Linking was performed with use of several common methods, and an optimal linkage model was recommended on the basis of a higher R 2 , strong intraclass correlation coefficient (ICC), and lower standard error (SE). The recommended model was further evaluated in subgroups based on age (<60 or ≥60 years), sex, etiology for presentation (traumatic versus atraumatic), and treatment type (operative versus nonoperative).

RESULTS

A total of 15,019 patients (mean age, 49 years; 54% female; 86% White) were included. The mean QuickDASH score (and standard deviation) was 37 ± 22, and the mean PROMIS PF CAT score was 45 ± 10. There was a strong negative linear relationship between the QuickDASH and PROMIS PF CAT (r = -0.73). The circle-arc linkage model demonstrated good accuracy and reliability (R 2 = 0.55; ICC = 0.71), and crosswalk tables were developed from this model. The subgroup analysis demonstrated age-related bias in the linkage model (root expected mean squared difference, 0.12). To address this, a separate crosswalk table was developed, which was dichotomized by age category.

CONCLUSIONS

The QuickDASH and PROMIS PF CAT scores were successfully linked. Utilization of the developed crosswalks-one specific to patients <60 years old and another specific to patients ≥60 years old-will allow for score interconversion in future meta-analyses and multicenter hand surgery studies.

Validation de L’échelle Unidimensionnelle D’Estime de Soi de Ducher (ESD): Validation of Ducher's Unidimensional Self-Esteem Scale (SES)

BACKGROUND

Although self-esteem is a relatively new concept, first developed in the field of social psychology, it has gained increasing importance in psychiatry, especially as a diagnostic criterion. However, it is poorly evaluated in clinical practice. The lack of an instrument allowing an easy global assessment may be the reason for this. It is therefore a question of validating a short, one-dimensional self-esteem scale in French, possibly allowing an evolutionary follow-up by self-correction.

METHODS

The study involved 106 patients with various psychiatric disorders, except psychotic disorder, stabilized or of varying severity. The creation of the original tool included 10 items. It was submitted to the selection of items followed by an exploratory factor analysis. The correlation between the items and the measurement of consistency and convergent validity were then performed.

RESULT

The evaluation of acceptability and distribution of results led to the selection of 6 items. Exploratory factor analysis revealed a unique dimension and good reliability (Tucker-Lewis Index = 0.89). No item displays correlations with a total score of less than 0.50 and the concept of construct is consistent. There is also a good internal consistency which confirms that the 6-item ESD version is optimal.

CONCLUSION

This new, validated scale will allow therapists to more accurately investigate the notion of self-esteem in a clinical or research setting.

Operative treatment of Mason Type III radial head fractures - A comparative analysis using PROMIS

Objectives

The purpose of this study is to evaluate the outcomes of operatively treated Mason Type III radial head fractures. Additionally, this project seeks to assess efficacy of PROMIS in evaluating post-operative outcomes for this patient population.

Methods

A total of 143 patients who underwent operative treated Mason Type III radial head fractures were analyzed retrospectively. PROMIS physical function (PF), PROMIS upper extremity (UE), PROMIS pain interference (PI), demographic variables, and range of motion were collected and analyzed over 12-month follow-up.

Results

Radial head arthroplasty (RHA) was performed on 89 patients, open reduction and internal fixation (ORIF) was performed on 47 patients, and radial head excision was performed on 7 patients. Among the RHA patients, PROMIS PF, PI and UE demonstrated a change of -1.33 (p < 0.05), -1.48 (p < 0.05), and 2.23 (p < 0.05) respectively from injury to 12-months. Among the ORIF patients, PROMIS PF, PI and UE demonstrated a change of 3.22 (p < 0.05), -1.56 (p < 0.05), and 2.09 (p < 0.05) respectively from injury to 12-months. At the pre-operative and 12-month visits, the RHA group demonstrated lower PROMIS PF scores 34.75 vs 38.02 (p < 0.05) and 33.42 vs 41.24 (p < 0.05) respectively. Ther was no difference in PROMIS PI, UE, or elbow range of motion between the two groups at 6- or 12-month follow-up (p > 0.05).

Conclusion

Comparing the RHA and ORIF groups, there was no difference in PROMIS PI or UE scores nor was there a clinically significant improvement at the 6- or 12-month mark. The ORIF group demonstrated improved PROMIS PF at all follow-up periods and did show a clinically significant improvement. Patient Acceptable Symptom State (PASS) correlated only with PROMIS UE at 6- and 12- months for both groups.

What does routine depression screening in the ambulatory orthopedic clinic teach us? Results from nearly 60,000 patient encounters

Background

It remains unclear what role depression screening plays in routine ambulatory orthopedic care. The purpose of this study was to determine (1) the floor and ceiling effects of the Patient-Reported Outcomes Measurement Information System Depression (PROMIS-D) form, (2) the prevalence of positive PROMIS-D screening forms across an orthopedic service line, and (3) the prevalence of previously diagnosed depression and interventions among a representative sample of patients.

Methods

This retrospective study analyzed 58,227 patients who presented to ambulatory orthopedic clinics across an orthopedic service line between January 1, 2019 to December 31, 2021. All patients completed a self-administered PROMIS-D form as part of the ambulatory encounter. Scores were analyzed with respect to patient characteristics including age, gender, and presenting orthopedic complaint. A sample of 1000 patients was evaluated for prevalence of depressive symptoms and formal psychiatric diagnosis and interventions in the 5 years preceding the clinic visit.

Results

PROMIS-D displayed a negligible ceiling effect (<0.001 %) but a large floor effect (19.0 %). PROMIS-D scores indicating depressive symptoms were highest among patients presenting with spine complaints (42.8 %) and lowest among patients presenting to orthopedic pediatric clinics (28.6 %). Women and those in the lowest quartile median household income (MHI) were more likely to report depressive symptoms. Among the 1000 patient sample, 31.3 % exhibited depressive symptoms. Of these, 39 % had previously received some form of mental health treatment, including 33.2 % who were prescribed antidepressants.

Conclusions

PROMIS-D is a useful screening questionnaire for patients in the orthopedic clinic, although there is a consistent floor effect. There are a number of patients who present to the orthopedic clinic who have depressive symptoms but have had no interaction with behavioral health. Given the impact depression can have on outcomes, screening for depressive symptoms should be considered as part of routine orthopedic practice.

The validity and reliability of the Turkish version of the 12-item Örebro musculoskeletal screening questionnaire (ÖMSQ-12-TR)

PURPOSE

The 12-item Örebro Musculoskeletal Screening Questionnaire (ÖMSQ-12) is a multidimensional questionnaire assessing general musculoskeletal problems. This study aimed to investigate its construct validity and reliability.

MATERIALS AND METHODS

Confirmatory factor analysis (CFA) was performed for construct validity. The Tampa Scale for Kinesiophobia (TSK) and the SF-12 and Pain Numerical Rating Scale (P-NRS) were used for convergent validity. Reliability (ICC), internal consistency (Cronbach's alpha), reproducibility, and known-group validity were assessed. The cut-off value was measured.

RESULTS

A total of n = 378 individuals (aged 35.7 ± 12.4 years, female = 73.3%) with a musculoskeletal problem participated in the study. P-NRS score of the individuals was 5. Results showed that a 3-factor model did fit well under CFA (χ2/df = 2.76 ≤ 3). The questionnaire had good reliability (ICC = 0.865) and internal consistency (α = 0.810). There were no floor or ceiling effects (<%15). Total ÖMSQ-12-TR scores had a correlation with the TSK, SF-12 and P-NRS (r = 0.303-0.609). The AUC for the risk of absenteeism from work was obtained as 0.738 (p < 0.001). The risk of absenteeism was high in individuals with an ÖMSQ-12-TR score of ≥57.5.

CONCLUSIONS

The ÖMSQ-12-TR is a valid and reliable questionnaire that can be used in determining the risk of absenteeism in musculoskeletal disorders and is convenient for online use.

Patient-reported outcomes measurement information system instruments in knee arthroplasty patients: a systematic review of the literature

BACKGROUND

The purpose of this study is to provide a systematic review of the literature pertaining to Patient-Reported Outcome Measurement Information System (PROMIS) validation and utilization as an outcomes metric in total knee arthroplasty (TKA) patients. This is the first systematic review on PROMIS use in total knee arthroplasty patients.

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. Study characteristics, patient demographics, psychometric properties (Pearson and Spearman correlation) with legacy patient-reported outcome measurement (PROM) instruments, floor and ceiling effects, responsiveness, and minimum clinically important difference (MCID) and PROMIS outcomes were recorded and analyzed.

RESULTS

Fifteen studies investigating PROMIS in 11,140 patients were included. The weighted-average Pearson correlation coefficient comparing PROMIS domains with legacy patient-reported outcome measurements in total knee arthroplasty patients was 0.62 [standard error (SE) = 0.06] and the weighted-average Spearman correlation comparing PROMIS domains with legacy patient-reported outcome measurements in total knee arthroplasty patients was 0.59 (SE = 0.06), demonstrating moderate-to-strong correlation and validity. There were no differences in weighted average floor [0.03% (SE = 3.1) versus 0% (SE = 0.1) versus 0.01% (SE = 1.1); p = 0.25] or ceiling effects [0.01% (SE = 0.7) versus 0.02% (SE = 1.4) versus 0.04% (SE = 3.5); p = 0.36] between PROMIS and legacy instruments. The weighted average for percentage of patients achieving MCID was 59.1% for global physical health (GPH), 26.0% for global mental health (GMH), 52.7% for physical function (PF), 67.2% for pain interference (PI), and 37.2% for depression.

CONCLUSION

Notably, PROMIS global physical health, physical function, and pain interference were found to be significantly responsive, with PROMIS pain interference most effectively capturing clinical improvement as evidenced by the achievement of MCID.

Psychometric properties of the Chinese version of the Arm Activity Measure in people with chronic stroke

Introduction

The Arm Activity Measure was developed to assess active and passive functions of the upper limb in people with unilateral paresis, but a Chinese version is not available and its psychometric properties have not been specifically tested in people with stroke. This study aimed to translate and culturally adapt the Chinese version of the Arm Activity Measure (ArmA-C) and establish its psychometric properties in people with chronic stroke.

Methods

The psychometric properties of ArmA-C were determined in 100 people with chronic stroke.

Results

The ArmA-C had good test-retest reliability (intraclass correlation coefficients [ICC] = 0.87-0.93; quadratic weighted Kappa coefficients = 0.53-1.00). A floor effect was identified in section A of the ArmA-C. The content validity and internal consistency (Cronbach's alpha coefficients = 0.75-0.95) were good. The construct validity of the ArmA-C was supported by acceptable fit to the two-factor structure model and significant correlations with the Fugl-Meyer Assessment for Upper Extremity score, grip strength, the Wolf Motor Function Test score, the Trail Walking Test completion time, and the Oxford Participation and Activities Questionnaire scores.

Conclusions

The ArmA-C is reliable and valid for assessing active and passive functions in people with chronic stroke.

Psychometric properties of the Chinese version of the functional assessment of chronic illness therapy-fatigue (FACIT-F) among patients with breast cancer

BACKGROUND

Fatigue is the most frequent and distressing symptom affecting the physical, cognitive, and affective domains of breast cancer patients. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) has been widely used in patients with chronic diseases and has shown satisfactory reliability and validity. This study aimed to examine the psychometric properties of the FACIT-F among Chinese patients with breast cancer.

METHODS

Using a convenience sampling method, a cross-sectional survey (January 2020 and September 2022) was used with patients recruited from two tertiary hospitals in Shanghai, Mainland China, and a total of 597 patients completed a demographic information questionnaire, the FACIT-F and the Functional Assessment of Cancer Therapy for Breast Cancer (FACT-B). Convergent validity was estimated by calculating the Pearson correlation coefficient of the FACIT-F with the FACT-B. Measurement invariance across age was performed by examining differential item functioning (DIF) across age groups (≤ 60 and > 60 years). The internal consistency and split-half reliability were performed for reliability analysis. Unidimensionality of the scale was evaluated by the principal component analysis by Rasch analysis. Additionally, Rasch analysis was performed for item difficulty levels, and an item-person map was used.

RESULTS

No floor/ceiling effects were observed for the FACIT-F. Moderate correlations were found between FACIT-F and FACT-B (r = - 0.342, p < 0.01). Most items showed an absence of DIF regarding age, except for one item. In addition, the FACIT-F showed acceptable internal consistency. Principal component analysis of Rasch residuals showed that the proportion of variance explained by the FACIT-F was 53.3%, and the outfit mean square statistics for the items ranged from 0.68 to 1.90 and the infit MNSQ from 0.63 to 1.73. Additionally, an acceptable response between items and persons was found.

CONCLUSIONS

The findings indicate that the Chinese version of the FACIT-F is a valid tool for the measurement of fatigue in breast cancer patients.

Non-operative Treatment of Mason Type I Radial Head Fractures: A Comparative Analysis Using Patient-Reported Outcomes Measurement Information System (PROMIS)

OBJECTIVES

The purpose of this study is to compare the outcomes of Mason type I radial head fractures. This information will help to provide physicians with a critical decision-making tool when considering non-operative intervention and evaluate Patient-Reported Outcomes Measurement Information System (PROMIS) as a potentially valuable measure to track outcomes.

METHODS

We retrospectively identified 527 patients undergoing non-operative intervention. Demographic information, physical exam measurements, patient acceptable symptom state (PASS), and PROMIS Upper Extremity (UE), Physical Function (PF), and Pain Interference (PI) scores were analyzed over 12 months.

RESULTS

At the initial outpatient post-injury visit (within one week of injury), the average PROMIS PF, UE, PI, and Depression were 42.04 (SD: 6.3), 35.31 (SD: 7.3), 59.18 (SD: 9.2), and 48.68 (SD: 6.8), respectively. The average change in PROMIS PF, UE, PI, and Depression scores from the time of injury to six weeks were -0.23 (p=0.7), 1.43 (p=0.03), -2.1 (p=0.01), and -0.99 (p=0.1). The average change in PROMIS PF, UE, PI, and Depression scores from the time of injury to six months was -0.56 (p=0.56), 1.84 (p<0.001), -1.84 (p<0.001), and -0.13 (p=0.68). Among patients initially reporting "not acceptable" on PASS and reporting "acceptable" at the six-month visit, the average PROMIS PF, UE, PI, and Depression scores were 42.14, 38.91, 56.91, and 47.51 respectively. This represents an average difference of 1.11 (p=0.07), 2.82 (p<0.01), -1.19 (p=0.04), and -1.7 (p=0.01) respectively.

CONCLUSION

PROMIS UE and PI significantly improved among Mason I radial head fractures treated non-operatively at both six-week and six-month follow-up points but did not meet the mean clinically important difference (MCID) PROMIS PF did not significantly differ between the time of injury, six-week or six-month follow-up points. Only PROMIS UE correlated with PASS at six-week and six-month follow-up. Among patients who improved from negative to positive responses on PASS, PROMIS UE, and PI significantly improved.

Development and validation of cultural competence assessment tool for healthcare professionals, India

Culture influences an individual's perception of "health" and "sickness". Therefore, cultural competence assessment of healthcare professionals is very important. Existing assessment scales have limited application in India due to the nation's rich cultural diversity and heterogeneous healthcare streams. This study was undertaken to develop and validate a cultural competence assessment tool for healthcare professionals in India. A cross-sectional study using convenience sampling was conducted following all standard steps among 290 healthcare professionals in India. Item reduction was followed by estimation of validity and reliability. Responses were recorded on a five-point Likert scale, ranging from strongly disagree to strongly agree. The resultant tool, named Cultural Competence Assessment Tool-India (CCT-I) showed an acceptable internal consistency (Cronbach's alpha =0.734). Inter-rater agreement was 81.43%. Face, content, and construct validity were demonstrated. There was no statistically significant difference in cultural competence between the healthcare streams based on years of clinical experience. There was statistically significant difference between streams of healthcare (p-value =0.009) and also between dentistry and Ayurveda groups (p-value = 0.003). This comprehensive tool can be used as the first step toward designing cultural competence training of healthcare manpower and the establishment of culturally sensitive healthcare organizations.

The Current Utilization of Patient-reported Outcome Measurement Information System in Shoulder, Elbow, and Sports Medicine

Clinical research using patient-reported outcome measures has been critical within the field of shoulder, elbow, and sports medicine in helping clinicians deliver evidence-based and value-based medicine. Recently, however, clinicians have advocated for improving the process of obtaining clinically meaningful information from patients while decreasing survey fatigue and increasing compliance. To that end, the National Institutes of Health created the Patient-Reported Outcome Measures Information System (PROMIS) in which a number of institutions and research investigations have adopted for reporting outcomes. A special focus has also been placed on PROMIS Computer Adaptive Testing forms, which tailor questioning through item response theory. The purpose of this study was to provide insight into the utilization, advantages, and disadvantages of PROMIS within the field of shoulder, elbow, and sports medicine and provide a comparison with legacy patient-reported outcome measure measurements.

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

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.

Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Instruments Compare Favorably With Legacy Patient-Reported Outcome Measures in Upper- and Lower-Extremity Orthopaedic Patients: A Systematic Review of the Literature

PURPOSE

To compare Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) with traditional ("legacy") patient-reported outcome measures (PROMs) in regard to correlations, ease of use, and quality criteria for upper (UE) and lower extremity (LE) orthopaedic conditions.

METHODS

A systematic search of the PubMed/MEDLINE database was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify published articles that referenced the various PROMIS PF measures. Two authors independently reviewed selected studies. The search returned 857 studies, 85 of which were selected for independent review by 2 authors. Of these, 54 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 6,074 UE and 9,366 LE patients. Overall, PROMIS PF measures demonstrated strong correlations with legacy PROMs among UE (weighted Pearson correlation, 0.624, standard error [SE] = 0.042; weighted Spearman correlation, 0.566, SE = 0.042) and LE patients (weighted Pearson correlation, 0.645, SE = 0.062; weighted Spearman correlation, 0.631, SE = 0.041). PROMIS PF questionnaires completed by UE patients had fewer questions than legacy PROMs (5.9 vs 17.7, P = .0093) and were completed in less time (90.5 vs 223.8 seconds, P = .084). PROMIS PF questionnaires completed by LE patients had fewer questions than legacy PROMs (4.81 vs 15.33, P < .001) and were completed in less time (63.6 vs 203.2 seconds, P = .0063). The differences for the reliability measures were not significant.

CONCLUSIONS

PROMIS PF scores correlate strongly with commonly used legacy PROMs in orthopaedics, particularly in UE and LE patients. PROMIS PF forms can be administered efficiently and to a broad patient population while remaining highly reliable. Therefore, they can be justified for standardized use among orthopaedic patients with UE and LE conditions, improving the ability to aggregate and compare outcomes in orthopaedic research.

Psychometric evaluation of the disabilities of the arm, shoulder and hand (DASH) in patients with orthopedic shoulder impairments seeking outpatient rehabilitation

STUDY DESIGN

This is a cross-sectional, observational study.

INTRODUCTION

The disability of the arm, shoulder and hand (DASH) questionnaire is an upper-extremity specific outcome measure commonly used in routine clinical care and clinical trials.

PURPOSE OF THE STUDY

Our purposes were to: (1) examine the psychometric properties of the DASH questionnaire using factor analysis, one- and two-parameter item response theory models, and (2) develop a functional staging map illustrating the relationships between the item difficulty hierarchy of the DASH items and the patient's DASH total score.

METHODS

Data from 2724 patients with orthopedic shoulder impairments seeking outpatient physical therapy in 79 clinics in the US were analyzed.

RESULTS

Factor analysis supported a general factor, explaining 62.2% of the total variance. The coverage of DASH items was suitable for patients with shoulder impairments with no ceiling or floor effect. Endorsed items representing the most difficult items were related to feeling less capable, executing recreational activities with force or impact, and performing recreational activities in which you move your arm freely. Items with higher discriminating abilities were those related to do heavy household chores, garden/yard work, and change a light bulb overhead. With a separation index equaled to 4.94, the DASH can differentiate persons into at least 6 statistically distinct person strata. None of the DASH items exhibited differential item functioning by gender or symptom acuity, except two items by age group.

DISCUSSION

Besides a total (summed) final score obtained from a specific measure, the keyform and functional staging plots/maps can be used to assist clinicians in clinical interpretation of the scores.

CONCLUSIONS

Results supported the clinical usage of the DASH questionnaire in patients with orthopedic shoulder impairments seeking outpatient rehabilitation.

Structural validity of the Arabic version of the disabilities of the Arm, Shoulder and Hand (DASH) using Rasch measurement model

Background

The disabilities of the arm, shoulder and hand (DASH) is a commonly used region-specific patient-reported outcome measure (PROM) that quantify upper extremity function (activity limitation) and symptoms. Current evidence suggests that measurement properties of the adapted versions of the DASH are not sufficiently examined. The Arabic DASH has evidence supporting its internal consistency, test–retest reliability, construct validity and responsiveness. On the other hand, the validity of the assumed unidimensionality of the Arabic DASH has not been examined previously. The aim of this study was to examine the structural validity of the Arabic DASH in patients with upper extremity musculoskeletal disorders using Rasch measurement model.

Methods

Patients with upper extremity musculoskeletal disorders were recruited and were asked to complete the Arabic DASH at their initial visit to physical therapy departments. The overall fit of the Arabic DASH to the requirement of the Rasch measurement model was examined using chi-square statistics for item-trait interaction, mean item and person fit residuals. The fit of individual items, thresholds ordering, local dependency, differential item functioning (DIF), and unidimensionality using the t-test approach were also examined.

Results

The Arabic DASH did not fit the Rasch measurement model initially (χ² = 179.04, p < 0.001) with major breach of local item independence and a pattern of high residual correlations among the activity-related items and among the impairment-related items. Combining items into activity-limitation and impairment testlets accommodated the local dependency and led to satisfactory fit of the Arabic DASH to the requirement of the Rasch measurement model (χ² = 3.99, p = 0.41).

Conclusions

Rasch measurement model supports the structural validity of the Arabic DASH as a unidimensional measure after the accommodation of local dependency.

Preoperative Evaluation of the Lower Extremity-Specific PROMIS Mobility Bank in Patients with ACL Tears

Purpose

The purpose of this study was to preoperatively assess the Patient-Reported Outcomes Measurement Information System (PROMIS) Item Bank v2.0–Mobility in patients with anterior cruciate ligament (ACL) tears to (1) determine construct validity by correlating with legacy patient-reported outcomes (PROs), (2) evaluate test burden, (3) determine the presence of floor or ceiling effects, and (4) revisit the conventional threshold for inclusiveness (floor/ceiling effects) in the modern era of computer adaptive testing (CAT)–based PROs.

Methods

Patients at a large academic musculoskeletal specialty center diagnosed with ACL tears indicated for surgery were administered the following outcomes measures before surgery: PROMIS Mobility CAT, PROMIS Pain Interference CAT (PROMIS PI), International Knee Documentation Committee (IKDC), the Marx Knee Activity Rating Scale (Marx), and Single Assessment Numeric Evaluation (SANE). Construct validity was evaluated using Spearman correlation coefficients. Correlation strengths were defined as high (≥0.7), high-moderate (0.61-0.69), moderate (0.4-0.6), moderate-weak (0.31-0.39) and weak (≤0.3). Number of questions to completion were recorded as a marker of test burden. The percentage of patients scoring at the extreme high (ceiling) or low (floor) of each measure was recorded to measure inclusivity.

Results

A total of 1126 patients were evaluated. The mean number of questions answered (± standard deviation) was 4.7 ± 2.1 for PROMIS Mobility and 4.5 ± 1.9 for PROMIS PI. PROMIS Mobility demonstrated a high correlation with IKDC, (r = 0.81, P < .001), a high-moderate correlation with PROMIS PI (r = −0.63), and a moderate correlation with SANE (r = 0.46, P < .01). Neither PROMIS Mobility nor PROMIS PI met conventional criteria for floor or ceiling effects (>15%).

Conclusions

The PROMIS Mobility measure maintains construct validity, because its scores correlate strongly with other PROs measuring physical function with high efficiency among preoperative patients with ACL injuries. Although ceiling effects of PROMIS Mobility CAT were below the conventional significance threshold of 15% at the preoperative timepoint in this population, this study provides critical feedback for redesigning the Mobility bank.

Establishing and comparing reference preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) scores in patients undergoing shoulder surgery

BACKGROUND

The Patient-Reported Outcomes Measurement Information System (PROMIS) has become increasingly popular among orthopedic surgeons treating shoulder pathology. Despite this, there have been few studies that have described and compared preoperative reference scores for specific shoulder surgical procedures. The primary purpose of this study was to establish and compare baseline preoperative PROMIS scores for 3 common types of shoulder surgery: rotator cuff repair (RCR), total shoulder arthroplasty (TSA), and labral repair (LR). The secondary goal was to stratify these operative groups by diagnosis and compare preoperative PROMIS scores.

METHODS

In this cross-sectional study, adult and pediatric patients who underwent surgery for either RCR, TSA, or LR were included. PROMIS-Upper Extremity (UE), PROMIS-Pain Interference (PI), and PROMIS-Depression (D) scores that were collected at each patient's preoperative visit were reviewed. Continuous and categorical variables were compared between operative groups using analysis of variance and χ² or Fisher exact tests, respectively. Multivariable general linear models were used to identify significant independent predictors of PROMIS scores when controlling for age, sex, and body mass index.

RESULTS

A total of 413 patients were included in the study: 272 in the RCR group, 84 in the TSA group, and 57 in the LR group. The average PROMIS-UE score was 39.8 in the LR group vs. 29.9 in the RCR group (P < .001) and 29.6 in the TSA group (P < .001). There was no difference between the mean RCR and TSA PROMIS-UE scores (P = .93). The average PROMIS-PI score was 56.6 in the LR group vs. 62.8 in the RCR group (P < .001) and 63.9 in the TSA group (P < .001). There was no difference between RCR and TSA PROMIS-PI scores (P = .09). The average PROMIS-D score was 43.5 in the LR group vs. 47.7 in the RCR group (P = .004) and 50.3 in the TSA group (P < .001). The TSA group had a higher mean PROMIS-D score than the RCR group (P = .03). For PROMIS-UE scores, age and body mass index were not found to be significant independent predictors (P = .98 and P = .88, respectively). For PROMIS-PI scores, age, body mass index, and sex were not found to be significant independent predictors (P = .31, P = .81, and P = .48, respectively).

CONCLUSION

Patients undergoing shoulder LR had higher preoperative function scores and lower pain interference and depression scores than those undergoing TSA and RCR. These baseline PROMIS scores should be taken into consideration when tracking a patient's outcomes after surgery, as a certain score could mean drastically different functional and pain outcomes depending on the underlying pathology.

Prospective Collection of PROMIS Physical Function Measure Demonstrates Significant Improvement After Bariatric Surgery

BACKGROUND

We evaluated quality of life among bariatric surgery patients using patient-reported outcomes (PROs). We hypothesized that physical function would improve after bariatric surgery.

METHODS

We prospectively collected PROs beginning in December 2015. We used the validated Patient-Reported Outcomes Measurement Information System (PROMIS) instruments because of their broad applicability and ability to use computer-adapted technology to survey. Measures are repeated at clinic visits, both pre- and postoperatively. Data were reviewed through February 2018. Data were analyzed comparing pre- and postop physical function PRO (PF PRO) by procedure: laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG). Additional variables were included in an adjusted linear mixed-effects regression model in order to isolate the effect of surgery on PF PRO over time.

RESULTS

This cohort included 279 bariatric surgery patients. The mean follow-up time was 1.5 years after surgery. The procedure groups were similar in terms of age and race but differed by gender and preoperative BMI. The PF-PRO measure showed significant improvement following surgery for both procedures.

CONCLUSION

Patient-reported physical function improved significantly after bariatric surgery. There was no significant difference between procedures.

Reporting and utilization of Patient-Reported Outcomes Measurement Information System® (PROMIS®) measures in orthopedic research and practice: a systematic review

BACKGROUND

The Patient-Reported Outcomes Measurement Information SystemⓇ (PROMISⓇ) is a dynamic system of psychometrically sound patient-reported outcome (PRO) measures. There has been a recent increase in the use of PROMIS measures, yet little has been written about the reporting of these measures in the field of orthopedics. The purpose of this study was to conduct a systematic review to determine the uptake of PROMIS measures across orthopedics and to identify the type of PROMIS measures and domains that are most commonly used in orthopedic research and practice.

METHODS

We searched PubMed, Embase, and Scopus using keywords and database-specific subject headings to capture orthopedic studies reporting PROMIS measures through November 2018. Our inclusion criteria were use of PROMIS measures as an outcome or used to describe a population of patients in an orthopedic setting in patients ≥ 18 years of age. We excluded non-quantitative studies, reviews, and case reports.

RESULTS

Our final search yielded 88 studies published from 2013 through 2018, with 57% (50 studies) published in 2018 alone. By body region, 28% (25 studies) reported PROMIS measures in the upper extremity (shoulder, elbow, hand), 36% (32 studies) reported PROMIS measures in the lower extremity (hip, knee, ankle, foot), 19% (17 studies) reported PROMIS measures in the spine, 10% (9 studies) reported PROMIS measures in trauma patients, and 6% (5 studies) reported PROMIS measures in general orthopedic patients. The majority of studies reported between one and three PROMIS domains (82%, 73 studies). The PROMIS Computerized Adaptive Test (CAT) approach was most commonly used (81%, 72 studies). The most frequently reported PROMIS domains were physical function (81%, 71 studies) and pain interference (61%, 54 studies).

CONCLUSION

Our review found an increase in the reporting of PROMIS measures over the recent years. Utilization of PROMIS measures in orthopedic populations is clinically appropriate and can facilitate communication of outcomes across different provider types and with reduced respondent burden.

REGISTRATION

The protocol for this systematic review was designed in accordance with the PRISMA guidelines and is registered with the PROSPERO database (CRD42018088260).

Comparison between Two Methods to Evaluate Function in Postoperative Breast Cancer Survivors

INTRODUCTION

Treatment for breast cancer can cause adverse effects such as pain and reduced upper limb function which can affect activities of daily living. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is the most used tool for evaluating function in breast cancer survivors. However, some specific aspects have raised discussions about its restricted coverage, which can generate several biases.

OBJECTIVE

To determine if DASH scores differed when assessed before and after task-oriented training (TOT) at 3 and 6 months after breast cancer surgery.

DESIGN

Prospective cohort study.

SETTING

Institutional study of 22 women assessed at 3 and 6 months after breast cancer surgery.

MAIN OUTCOME MEASURES

The DASH questionnaire and TOT assessment. Two correlation tests were performed: Spearman's correlation between the total score of the two DASH scores (pre- and post-TOT) and the Kendall's tau correlation between each of the items.

RESULTS

There was a moderate and excellent correlation between final DASH scores, pre- and post-TOT, at both 3 and 6 months postoperatively. However, when assessed individually, most of the DASH items were poorly correlated. There was also no agreement between the total DASH scores pre- and post-TOT as assessed by Bland-Altman plots.

CONCLUSION

Both the DASH and TOT are considered useful in clinical practice to assess upper limb function, although the use of TOT in some of the DASH items may reduce memory bias and improve skills estimation.

Accuracy and Validity of Computer Adaptive Testing for Outcome Assessment in Patients Undergoing Total Knee Arthroplasty

BACKGROUND

Computerized adaptive test (CAT) questionnaires may allow standardization of patient-reported outcome measures and reductions in questionnaire burden. We evaluated the validity, accuracy, and efficacy of a CAT system in patients with end-stage osteoarthritis undergoing total knee arthroplasty.

METHODS

CAT Knee Osteoarthritis Outcome Scores (KOOS) and CAT KOOS-JR questionnaires were applied to 1871 standard form KOOS and 1493 KOOS-JR patient responses, respectively. Mean, standard deviations, Pearson's correlation coefficients, interclass correlation coefficients (ICCs), frequency distribution plots, and Bland-Altman plots were used to compare the precision, validity, and accuracy between CAT scores and full-form scores.

RESULTS

There was a mean reduction of 14 questions (33%) in the CAT KOOS and 1.4 questions (20%) with the CAT KOOS-JR version, compared with the standard KOOS and KOOS-JR surveys, respectively. There were no significant differences between KOOS and CAT KOOS scores with respect to pain (P = .66), symptoms (P = .43), quality of life (P = .99), activities of daily living (P = .68), and sports (P = .84). Similarly, there were no significant differences between the standard form KOOS-JR and CAT KOOS-JR scores (P = .94). There were strong correlations with minimal variability between the CAT KOOS and standard KOOS questionnaires for pain (r = 0.98, ICC: 0.98), symptoms (r = 0.97, ICC: 0.97), quality of life scores (r = 0.99, ICC: 0.99), activities of daily living scores (r = 0.99, ICC: 0.99), and sports scores (r = 0.99, ICC: 0.99). Similarly, there were strong correlations between the KOOS-JR and the CAT KOOS-JR scores (r = 0.99, ICC: 0.99).

CONCLUSION

CAT KOOS and the CAT KOOS-JR versions are accurate and reduce questionnaire burden up to one-third compared with standard surveys. CAT versions may improve patient compliance and decrease fatigue.

Patient-Reported Outcome Measures and Health-Related Quality-of-Life Scores of Patients Undergoing Anatomic Total Shoulder Arthroplasty

BACKGROUND

Health-related quality-of-life (HRQoL) scores are required for cost-effectiveness and health-care value analysis. We evaluated HRQoL scores and patient-reported outcome measures (PROMs) in patients with advanced glenohumeral osteoarthritis treated with anatomic total shoulder arthroplasty to establish values of HRQoL scores that can be used for cost-effectiveness and value analysis and to assess relationships between HRQoL scores and shoulder and upper-extremity PROMs.

METHODS

We analyzed 143 patients (143 shoulders) with glenohumeral osteoarthritis treated with anatomic total shoulder arthroplasty; 92 patients had 1-year follow-up. Preoperative and postoperative functional outcomes were assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) score, the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST), and a visual analog scale (VAS) for shoulder pain and function. Health utility was assessed with the EuroQol-5 Dimensions (EQ-5D), Short Form-6 Dimensions (SF-6D), and VAS Quality of Life (VAS QoL). HRQoL score validity was determined through correlations between the PROMs and HRQoL scores. The responsiveness of HRQoL scores was measured through the effect size and the standardized response mean.

RESULTS

There were significant improvements in all PROMs and HRQoL scores (p < 0.001) at 1 year after the surgical procedure. The changes in VAS QoL (very weak to moderate), EQ-5D (weak), and SF-6D (weak) were significantly correlated (p < 0.05) with the changes in PROMs, demonstrating comparably acceptable validity. There were large effect sizes in the VAS QoL (1.843), EQ-5D (1.186), and SF-6D (1.084) and large standardized response mean values in the VAS QoL (1.622), EQ-5D (1.230), and SF-6D (1.083), demonstrating responsiveness. The effect sizes of all PROMs were larger than those of the HRQoL scores.

CONCLUSIONS

PROMs and HRQoL scores are not interchangeable, and studies of the cost-effectiveness and value of shoulder arthroplasty should incorporate both shoulder and upper-extremity PROMs and HRQoL scores. The findings of this study provide data on HRQoL scores that are specific to the treatment of advanced glenohumeral osteoarthritis with anatomic total shoulder arthroplasty and can be used for future cost-effectiveness and value analysis studies.

Patient-Reported Outcomes Measurement Information System (PROMIS) Instruments Correlate Better With Legacy Measures in Knee Cartilage Patients at Postoperative Than at Preoperative Assessment

PURPOSE

To define the psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), Pain Interference (PI), and Depression computer adaptive tests (CATs) in patients undergoing knee cartilage surgical procedures.

METHODS

The PROMIS PF, PI, and Depression CATs were administered preoperatively and at 6 months alongside legacy knee patient-reported outcome measures (PROMs) in patients undergoing knee cartilage surgical procedures. Statistical analysis consisted of the time to completion, psychometric analysis for correlative strengths, absolute and relative floor and ceiling effects, and Cohen effect size.

RESULTS

Our study included 250 patients (57.2% male patients), averaging 1.87, 1.53, and 1.91 minutes for completion of the PF, PI, and Depression CATs, respectively. Preoperatively, the PROMIS PF and PI CATs showed wide ranges of correlation coefficients with respect to function (r = 0.14-0.72 and r = 0.29-0.77, respectively) and health-related quality-of-life PROMs (r = 0.64-0.70). At 6 months, the PROMIS PF CAT (r = 0.82-0.93) and PI CAT (r = 0.77-0.93) both exhibited excellent correlations with respect to legacy function and health-related quality-of-life PROMs except for the Marx Activity Rating Scale (r = 0.36-0.44). None of the PROMIS instruments exhibited any significant floor or ceiling effects.

CONCLUSIONS

The PROMIS PF, PI, and Depression CATs performed better with respect to legacy PROMs in the postoperative period than the preoperative period. In addition, the PROMIS PF and PI measures performed best with respect to the International Knee Documentation Committee questionnaire, and no floor or ceiling effects were identified for the PROMIS instruments. The PROMIS instruments may be more suited to track outcomes postoperatively than to establish preoperative baselines in cartilage surgery patients.

The structural validity of the Finnish version of the Disabilities of the Arm, Shoulder and Hand: A Rasch model analysis

Introduction

The construct validity of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) has previously been questioned. The purpose of this study was to evaluate the measurement properties of the Finnish version of the DASH for assessing disability in patients with hand complaints using Rasch Measurement Theory.

Methods

A cohort of 193 patients with typical hand and wrist complaints were recruited at a surgery outpatient clinic. The DASH scores were analysed using the Rasch model for differential item functioning, unidimensionality, fit statistics, item residual correlation, coverage/targeting and reliability.

Results

In the original DASH questionnaire, the item response thresholds were disordered for 2 of 30 of the items. The item fit was poor for 9 of 30 of the items. Unidimensionality was not supported. There was substantial residual correlation between 87 pairs of items. Item reduction (chi square 95, degrees of freedom 50, p < 0.001) and constructing two testlets led to unidimensionality (chi square 0.64, degrees of freedom 4, p = 0.96). Person separation index was 0.95. The testlets had good fit with no differential item functioning towards age or gender.

Conclusion

Unidimensionality of the original Finnish version of the DASH was not supported, meaning the questionnaire seems to gauge traits other than disability alone. Hence, the clinician must be careful when trying to measure change in patients’ scores. Item reduction or the creation of testlets did not lead to good alternatives for the original Finnish DASH. Differential item functioning showed that the original Finnish scale exhibits minor response bias by age in one item. The original Finnish DASH covers different levels of ability well among typical hand surgery patients.

What Are the Floor and Ceiling Effects of Patient-Reported Outcomes Measurement Information System Computer Adaptive Test Domains in Orthopaedic Patients? A Systematic Review

PURPOSE

To perform a systematic review to answer the following: (1) What are the floor and ceiling (F/C) effects of the Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive test (CAT) domains of physical function (PF), upper extremity physical function (UE), pain interference (PI), and depression (D) in adult orthopaedic patients? (2) Do the PROMIS-PF and PROMIS-PI domains have differing F/C effects depending on use in upper extremity, lower extremity, spine, neck, and back, or trauma patients?.

METHODS

(Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines were followed, the review was registered on PROSPERO, and the methodological index for non-randomized studies was used for this systematic review. Studies reporting the F/C effects of at least 1 of 4 PROMIS CAT domains in orthopaedic patient cohorts accessed through PubMed and Embase on October 30, 2018, were included. F/C effects for each study were reported within forest plots.

RESULTS

Forty-three studies were included. Generally, varying cohorts demonstrated no F/C effects for PROMIS-PF (0%-9.0%), variable ceiling effects for PROMIS-UE (lower in v2.0; 0%-28.2%), variable floor effects for PROMIS-PI (0%-19.0%), and significant floor effects for PROMIS-D (0.4%-23.4%).

CONCLUSIONS

The orthopaedic literature demonstrated generally favorable floor and ceiling effects for PROMIS CAT domains, with the exception of variable ceiling effects for PROMIS-UE (the newer version exhibits only minor effects), variable floor effects for PROMIS-PI, and significant floor effects for PROMIS-D. In addition, the F/C effects of PROMIS-PF did not vary based on patient population. Although the floor effects of PROMIS-PI did vary based on patient population, the variability does not appear to be based solely on anatomic location. The PROMIS-PF and PROMIS-UE v2.0 demonstrate consistently low floor and ceiling effects. However, the PROMIS-PI and PROMIS-D may need modification before widespread adoption for clinical and research purposes.

Association of Patient-reported Outcomes With Clinical Outcomes After Distal Humerus Fracture Treatment

In this study, we assessed the patient-reported outcomes of distal humerus fracture treatment using Patient-Reported Outcomes Measurement Information System (PROMIS) or QuickDASH (Disabilities of the Arm, Shoulder, and Hand) scores and the association between patient-reported outcomes and clinical outcomes.

Methods

We performed a retrospective cohort study of 76 adult patients who sustained an acute distal humerus fracture between 2016 and 2018; 53 patients completed at least one patient-reported outcome measure used to assess physical function (PF) during their routine follow-up care (69.7% response rate). The average time to follow-up patient-reported outcome measure was 10.3 months. Patients completed the PROMIS PF 10a, PROMIS upper extremity (UE) 16a, and/or QuickDASH based on the treating institution/service. In addition, the PROMIS Global (Mental) subscale score was used as a measure of self-rated mental health. To assess clinical outcomes, we measured radiographic union, range of motion, and postoperative complications.

Results

Most fractures were intra-articular (67.9%), and 84.9% were treated surgically. After treatment, 98.1% of fractures united radiographically. By the final follow-up, the average arc of motion was 18° to 122°. Average (±SD) PROMIS PF and UE scores were 41.7 ± 11.1 and 40.8 ± 12.4, respectively. The average QuickDASH score was 39.4 ± 26.5. The arc of flexion-extension and PROMIS Global (Mental) score were independently associated with PROMIS PF and PROMIS UE scores.

Conclusions

We found that clinical factors (the arc of flexion-extension) and patient psychological factors (PROMIS Global [Mental] score) were independently associated with PROMIS measures of PF after distal humerus fracture treatment. These data can be used to contextualize patient outcomes and guide patient expectations.

Floor and Ceiling Effects, Time to Completion, and Question Burden of PROMIS CAT Domains Among Shoulder and Knee Patients Undergoing Nonoperative and Operative Treatment

The Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive tests (CATs) have emerged as an efficient technique for measuring patient-reported outcomes among orthopaedic patients. The purpose of this study was to investigate the floor and ceiling (F/C) effects, time to completion (TTC), and question burden of PROMIS CATs administered to patients presenting to a shoulder and sports medicine orthopaedic clinic.

The Remote Completion Rate of Electronic Patient-Reported Outcome Forms Before Scheduled Clinic Visits-A Proof-of-Concept Study Using Patient-Reported Outcome Measurement Information System Computer Adaptive Test Questionnaires

INTRODUCTION

Patient-Reported Outcome Measurement Information System (PROMIS) questionnaires are amenable to remote administration. This study sought to determine remote completion rates of PROMIS questionnaires before clinic visits.

METHODS

Patients were e-mailed a set of PROMIS forms. Completion rates were analyzed by visit type, provider seen, and patient demographics.

RESULTS

Seven hundred forty total appointments were included. Sixty-seven percent of encounters had previsit form completion. High completion rates were found for all visit types (74%, 67%, and 64% for new, return, and postoperative visits, respectively). Women had a higher completion rate than men (71% versus 64%; P = 0.031). White patients (72%; P = 0.001) and patients in the third median household income quartile ($53,725 to $83,088; 72%; P = 0.008) had higher completion rates than their respective counterparts.

CONCLUSION

Most patients remotely completed PROMIS forms. The efficiency and accessibility of PROMIS forms may help improve ease of collection of patient-reported outcomes.

Patient-Reported Outcomes Measurement Information System physical function correlates with Toronto Extremity Salvage Score in an orthopaedic oncology population

BACKGROUND

The National Institute of Health's Patient-Reported Outcomes Measurement Information System (PROMIS) uses computerised-adaptive testing to reduce survey burden and improve sensitivity. PROMIS is being used across medical and surgical disciplines but has not been studied in orthopaedic oncology.

QUESTIONS/PURPOSES

The aim of the study was to compare PROMIS measures with upper extremity (UE) and lower extremity (LE) Toronto Extremity Salvage Score (TESS) by assessing the following: (1) responder burden, (2) correlation between scores and (3) floor/ceiling effects.

PATIENTS AND METHODS

This cross-sectional trial analysed all 97 adult patients treated surgically for a bone or soft tissue tumour at a tertiary institution between November 2015 and March 2016. TESS (UE or LE) and PROMIS (Physical Function, Pain Interference and Depression) surveys were administered preoperatively. Pearson correlations between each PROMIS domain and TESS were calculated, as were floor/ceiling effects of each outcome measure.

RESULTS

(1) Completion of three PROMIS questionnaires required a mean total of 16.8 (+/- 5.8 standard deviation) questions, compared with 31 and 32 questions for the LE and UE TESS questionnaires, respectively. (2) The PROMIS Physical Function scores demonstrated a strong positive correlation with the LE TESS (r = 0.84; 95% confidence interval [CI], 0.72-0.91; p < 0.001) and moderate positive correlation with the UE TESS (r = 0.64; 95% CI, 0.34-0.83; p = 0.055). The PROMIS Depression scores demonstrated a weak negative correlation with both the LE TESS (r = -0.38; 95% CI, -0.61 to -0.10; p = 0.010) and with UE TESS (r = -0.38; 95% CI, -0.67 to -0.01; p = 0.055). The PROMIS Pain Interference scores demonstrated a strong negative correlation with the LE TESS (r = -0.71; 95% CI, -0.83 to -0.52; p < 0.001) and a moderate negative correlation with the UE TESS (r = -0.62; 95% CI, -0.81 to -0.30; p = 0.001). (3) The UE TESS had a range of scores from 16 to 100 with a 27% ceiling effect and no floor effect, and the LE TESS had a range from 10 to 98 with no floor or ceiling effect. There was no floor or ceiling effect for any PROMIS measures.

CONCLUSIONS

In an orthopaedic oncology population, the PROMIS Physical Function and Pain Interference scores correlate with the TESS and have the benefit of reduced survey burden and ceiling effect. The PROMIS Depression scores may provide additional information regarding patient outcomes not captured by the TESS.

THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE

Patient reported outcome measures asses patients' symptoms, function and health-related quality of life and are designed to capture more clinical information than can be gathered by objective medial testing alone. As reimbursements and the understanding of patient outcomes are becoming tied to performance on PROMIS measures, it is an important step to establish how PROMIS measures correlate and compare to traditional legacy measures.

Patient-Reported Outcome Measures and Health-Related Quality-of-Life Scores of Patients Undergoing Anatomic Total Shoulder Arthroplasty

BACKGROUND

Health-related quality-of-life (HRQoL) scores are required for cost-effectiveness and health-care value analysis. We evaluated HRQoL scores and patient-reported outcome measures (PROMs) in patients with advanced glenohumeral osteoarthritis treated with anatomic total shoulder arthroplasty to establish values of HRQoL scores that can be used for cost-effectiveness and value analysis and to assess relationships between HRQoL scores and shoulder and upper-extremity PROMs.

METHODS

We analyzed 145 patients (145 shoulders) with glenohumeral osteoarthritis treated with anatomic total shoulder arthroplasty; 93 patients had 1-year follow-up. Preoperative and postoperative functional outcomes were assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) score, the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST), and a visual analog scale (VAS) for shoulder pain and function. Health utility was assessed with the EuroQol-5 Dimensions (EQ-5D), Short Form-6 Dimensions (SF-6D), and VAS Quality of Life (VAS QoL). HRQoL score validity was determined through correlations between the PROMs and HRQoL scores. The responsiveness of HRQoL scores was measured through the effect size and the standardized response mean.

RESULTS

There were significant improvements in all PROMs and HRQoL scores (p < 0.001) at 1 year after the surgical procedure. The changes in VAS QoL and EQ-5D were significantly correlated (weak to moderate) with the changes in all PROMs except the SST, demonstrating comparably acceptable validity. The VAS QoL had a large effect size (1.833) and standardized response mean (1.603), and the EQ-5D also had a large effect size (1.163) and standardized response mean (1.228), demonstrating responsiveness. The effect sizes of all PROMs were larger than those of the HRQoL scores. The change in SF-6D had only a moderate effect size and standardized response mean and was not significantly correlated with the change in any of the PROMs.

CONCLUSIONS

PROMs and HRQoL scores are not interchangeable, and studies of the cost-effectiveness and value of shoulder arthroplasty should incorporate both shoulder and upper-extremity PROMs and HRQoL scores. The findings of this study provide data on HRQoL scores that are specific to the treatment of advanced glenohumeral osteoarthritis with anatomic total shoulder replacement and can be used for future cost-effectiveness and value analysis studies.
