The responsiveness of the PROMIS instruments and the qDASH in an upper extremity population

Evaluation of Test-Retest Reliability for the Patient-Reported Outcomes Measurement Information System Upper Extremity and Pain Interference Computer Adaptive Tests in a Hand Surgery Population

PURPOSE

Utilization of the Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) and pain interference (PI) computer adaptive tests (CAT) has grown in the hand surgery literature. However, these instruments were derived using data from a general population rather than cohorts with UE pathology. As such, our primary purpose was to evaluate the test-retest reliability of the UE and PI CATs in a sample of hand surgery patients.

METHODS

At a tertiary academic center, we recruited adult (≥18 years) orthopedic hand surgery patients who completed the PROMIS UE and PI CAT 1-7 days prior to their office appointment, plus a subsequent response to both instruments in clinic. Patients were included only if their upper extremity symptoms were stable between questionnaires, as assessed by an anchor question (eg, no change in scores is expected). Intraclass correlation coefficients (ICCs) were used to assess test-retest reliability. Bland-Altman Plots were created to visualize the proportion of patients whose scores differed by a value greater than the minimally clinically important difference for both instruments (4.1 for UE CAT, 4.3 for PI CAT).

RESULTS

The 88 included patients had a mean age of 54 ± 18 years, and 56% (56/88) were women. There was a mean of 4 ± 2 days between surveys. The UE CAT demonstrated an ICC of 0.87 (95% confidence intervals [CI], 0.80-0.91), consistent with "good" to "excellent" reliability. The PI CAT ICC was 0.84 (95% CI, 0.76-0.89), consistent with "good" reliability. However, 34% (30/88) and 23% (20/88) of patients had UE CAT and PI CAT score differences that exceeded minimally clinically important difference thresholds.

CONCLUSIONS

For a hand surgery cohort (population level), the UE CAT demonstrated "good" to "excellent" test-retest reliability, and the PI CAT demonstrated "good" reliability. However at the patient level, score differences were clinically relevant in approximately one of three patients for UE CAT and one of four patients for the PI CAT. We conclude that these instruments are reliable at the population level, but should not be used at the level of individual hand surgery patients.

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.

Evaluation of fluoroscopically guided transforaminal epidural steroid injections for cervical radiculopathy utilizing patient reported outcome measurement information system as an outcome measure

Background

Cervical radiculopathy is a common cause of pain. For patients who fail conservative management, a transforaminal epidural steroid injection (TFESI) is an accepted intervention and alternative to decompression surgery.

Objective

The purpose of this study was to evaluate the therapeutic effect of TFESIs for patients with cervical radiculopathy.

Methods

Adult patients treated at a multidisciplinary, tertiary academic spine center with cervical radicular pain and MRI evidence of corroborative cervical spondylotic foraminal stenosis and who had failed at least 6 weeks of conservative management consisting of medication and physical rehabilitation were included in this study. Patient Reported Outcome Measurement Information System (PROMIS) domains of Physical Function (PF) v1.2/v2.0 and Pain Interference (PI) v1.1 were collected at baseline and at 3-, 6-, and 12-month follow-up visits. Statistical analysis comparing baseline score with follow-up post-procedural PROMIS scores was performed. The percentage of patients who reported improvement exceeding the minimal clinically important difference was calculated for survey responders and for the worst case scenario.

Results

87 patients met inclusion criteria. PROMIS PI at 3-, 6-, and 12-months follow-up statistically improved by 2.2 (95 % confidence interval [CI] 2.1-2.4, p = 0.02), 2.3 (95 % CI 2.1-2.5, p = 0.03), and 2.7 (95 % CI 2.5-3.0, p = 0.03) points, respectively. Follow-up PROMIS PF score did not significantly differ from baseline scores. The percentage of patients that exceeded MCID thresholds of clinical significance was 59 % (95 % CI 47%-70 %) at 3-months, 52 % (95 % CI 41%-63 %) at 6-months, and 60 % (95 % CI 50%-72 %) at 12-months. Worst case scenario analysis demonstrated that 51 % (95 % CI 39%-62 %) of patients exceeded the MCID thresholds at 3-months, 32 % (95 % CI 22%-43 %) at 6-months, and 23 % (95 % CI 13%-33 %) at 12-months.

Conclusions

Our study demonstrated that TFESI leads to a long-term improvement up to a year in pain for patients with cervical radiculopathy.

PROMIS-9 UE physical function demonstrates moderate responsiveness for patients following upper limb prosthesis intervention

BACKGROUND

Upper extremity physical function is an essential health domain in the rehabilitation care for patients with upper limb amputation or absence. The PROMIS-9 UE Physical Function short form is a recently established instrument designed for individuals with upper limb amputation or absence. The instrument's responsiveness to changes after receiving a prosthesis has not been investigated. The current study aimed to evaluate the ability of the PROMIS-9 UE to detect changes in bimanual (two-handed) functional capacity after patients' receipt of a prosthesis.

METHODOLOGY

A retrospective chart review was conducted on the longitudinal PROMIS-9 UE outcome measure scores completed between April 2016 and February 2024. Participants included individuals with an outcome collected before and after prosthesis receipt.

RESULTS

The final sample size included 124 individuals (91 male, 33 female; 43.4 ± 15.0 years old, 34.4 ± 103.0 months since amputation, and 62.9% injury etiology). Analyses found significant improvement across all patients in the PROMIS-9 UE scores from baseline to post prosthesis intervention (baseline: 25.3 ± 8.6, post: 29.5 ± 9.6; p < 0.001). The PROMIS-9 UE demonstrated a moderate responsiveness (Standardized Response Mean = 0.6) to prosthetic intervention. This was a directional change consistent with subjective patient reports of increased functionality. Furthermore, findings from the linear mixed model demonstrated significant responsiveness for the PROMIS-9 UE instrument to detect post-intervention changes after controlling for potential confounding effects (p < 0.001).

CONCLUSIONS

These findings suggest the PROMIS-9 UE Physical Function instrument demonstrates moderate clinical utility in capturing patient progress following upper limb prosthesis intervention.

External Fixation Prior to Fasciectomy Leads to Substantial Improvement of Advanced Dupuytren's PIP Contractures at Mean Follow-up 15 Months

BACKGROUND

The Digit Widget is an external fixation device that can be used to reverse proximal interphalangeal joint (PIPJ) contractures in the hand. Our hypothesis is that usage of the Digit Widget prior to fasciectomy in patients with severe Dupuytren's proximal interphalangeal (PIP) contractures will result in short-term improvement and maintenance of the PIPJ contracture after fasciectomy.

METHODS

Patients who underwent placement of the Digit Widget soft tissue distractor prior to fasciectomy for Dupuytren's disease were identified between January 2015 and December 2018. Multiple fingers were considered separately. Patient Reported Outcome Measurement Information System (PROMIS) Physical Function (PF), Pain Interference, and Depression scores were collected. Patients treated for contractures from etiologies other than Dupuytren's were not included. Multiple linear regression was used to compare initial PIP contractures, PF scores, and final contractures.

RESULTS

There were 28 fingers in 24 patients with average age of 56 ± 12 (30.5-69.9) years. Initial mean PIPJ contracture was 81° (50°-120°), which had corrected to 23° at time of removal. Average time between application and fasciectomy was 58 (28-112) days. At final follow-up, average 449 (58-1641) days, the average contracture was 39° (0°-105°). Contracture immediately following fasciectomy was found to be strongly correlated with the contracture at final follow-up. There was no statistical relationship between final PROMIS PF scores and final change in contracture.

CONCLUSIONS

Digit Widget external fixation is an effective treatment for the correction of advanced PIPJ contractures related to Dupuytren's disease, with an average of 52% improvement in contracture at 15 months.

Comparative responsiveness of the PROMIS-29 and SF-36 instruments in individuals with chronic musculoskeletal pain

BACKGROUND

Chronic musculoskeletal pain (CMP) impacts Health-Related Quality of Life (HRQoL). Several questionnaires are widely used for evaluating the HRQoL, such as Patient Reported Outcomes Measurement Information System 29-item Health Profile (PROMIS-29) and 36-Item Short Form Health Survey (SF-36). This study aimed to assess and compare the responsiveness of PROMIS-29 and SF-36 in individuals with CMP.

METHODS

The prospective study collected data from 215 patients with CMP. The participants completed both questionnaires at baseline and a 4-week follow-up with the global perceived effect (GPE) scale. The internal and external responsiveness methods evaluated the responsiveness of the instruments. The effect size (ES) and standardized response mean (SRM) assessed the internal responsiveness. External responsiveness was measured by Spearman's correlation coefficients (r) and area under the receiver operating curve (AUC). The responsiveness of the PROMIS-29 and SF-36 were compared in similar constructs.

RESULTS

The PROMIS-29 demonstrated responsiveness as moderate in fatigue (ES = -0.79, SRM = -0.64), moderate to large in pain interference (ES = -0.94, SRM = -0.64), and large effect in pain intensity subscale (ES = -1.25, SRM = -1.16). The SF-36 bodily pain exhibited moderate responsiveness (ES = 0.73, SRM = 0.60). Spearman's correlation showed moderate between GPE and change scores of PROMIS-29 physical function (r = 0.31), fatigue (r = -0.36), pain intensity (r = 0.45), and weak between GPE and changes score of SF-36 (r = 0.15-0.26). Besides, the AUC of the PROMIS-29 fatigue, and pain intensity scale were 0.701 and 0.725, respectively, indicating superior discriminative ability.

CONCLUSIONS

The PROMIS-29 and SF-36 were the most responsive in assessing the pain domain for physical health and PROMIS-29 fatigue domain for mental health among individuals with CMP. The PROMIS-29 demonstrated superior results compared to the SF-36. Other domains related to HRQoL could be considered in other assessment instruments.

Evaluation of Fluoroscopically Guided Transforaminal Selective Nerve Root Sleeve Injections for Lumbar Spinal Stenosis With Radiculopathy Utilizing Patient Reported Outcome Measurement Information System as an Outcome Measure

OBJECTIVE

To evaluate the therapeutic effect of transforaminal selective nerve root sleeve injections (TFSNRIs) in a specific subset of patients with clinical symptoms and presentation consistent with spinal stenosis.

DESIGN

Retrospective review.

SETTING

Tertiary academic spine center.

PARTICIPANTS

A total of 176 patients with radicular leg pain with or without low back pain as well as ≥3 clinical features of spinal stenosis and corroborative radiographic features of spinal stenosis on lumbar spine magnetic resonance imaging without confounding spinal pathology (N=176).

INTERVENTIONS

Fluoroscopically guided transforaminal selective nerve root sleeve injections.

MAIN OUTCOME MEASURES

Patient Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) v1.2/v2.0, Pain Interference (PI) v1.1, and PROMIS (D) v1.0 were collected at baseline and post-procedure short term (<3-months) and long-term (6-12 month) follow-up. Statistical analysis comparing baseline and postprocedural PROMIS scores was performed. Differences were compared with previously established minimal clinically important differences in the spine population.

RESULTS

For patients with spinal stenosis treated with TFSNRI, no statistically significant improvement was observed short- and long-term follow-up in PROMIS PF (P=.97, .77) and PROMIS Depression (P=.86, .85) scores. At short-term follow-up, PROMIS PI scores did significantly improve (P=.01) but the average difference of pre- and post-procedure scores did not reach clinical significance. No significant difference in PROMIS PI was noted at long-term follow-up (.75).

CONCLUSIONS

Although a statistically significant difference was observed for improvement in pain, in this retrospective study, TFSNRI did not provide clinically significant improvement in patients' function, pain, or depression for lumbar spinal stenosis at short- and long-term follow-up.

Crosswalk between the PROMIS physical function CAT and PROMIS upper extremity CAT v1.2 in a hand surgery population

BACKGROUND

There is no gold standard patient-reported outcome measure (PROM) in hand surgery. As a result, a diverse array of PROM instruments have been utilized across centers over time. Lack of score interchangeability limits the ability to compare or conglomerate scores when new instruments are introduced. Our aim was to develop a linkage for the PROMIS UE CAT v1.2 and PROMIS PF CAT scores and develop crosswalk tables for interconversion between these PROMs.

METHODS

Retrospective review was conducted to identify adult (≥ 18y) patients seen by orthopaedic hand surgeons at a single academic tertiary care hospital who had completed PROMIS UE CAT v1.2 and PROMIS PF CAT score at the same visit. For those with multiple visits, only one randomly selected visit was included in the analyses. Pearson's correlation was calculated to determine the linear relationship between the scores. Linkage from PF to UE was performed utilizing several commonly utilized equating models (identity, mean, linear, equipercentile and circle-arc methods). The performance of the models was assessed using intraclass correlation (ICC) between observed PROMIS UE CAT v1.2 and estimated PROMIS UE CAT v1.2 scores generated using the model as well as Root Mean Square Error (RMSE). The model chosen as the 'best' was further assessed for population invariance using root expected mean squared difference (REMSD) where < 0.08 were considered good.

RESULTS

Of 10,081 included patients, mean age was 48.3 (SD = 17.0), and 54% were female (5,477/10,081). Mean UE CAT v1.2 and PF CAT scores were 37 (SD = 9.8) and 46 (SD = 10.0), respectively. There was a strong correlation between the scores (Pearson correlation r = 0.70). All methods performed acceptably (ICC ≥ 0.66 and RMSE < = 7.52 for all). The equipercentile method had the highest ICC (ICC = 0.70 (95% CI 0.69-0.71)) while the mean and circle arc methods had the lowest RMSE. The circle arc method is the most reliable with the smallest standard error and has satisfactory population invariance across age group (REMSD 0.065) and sex (REMSD 0.036).

CONCLUSIONS

Crosswalk tables to be used for bidirectional conversion between scores were created.

When Do Patients Achieve PROMIS Milestones After Rotator Cuff Repair?

Background

Given the variability of the questions asked, the Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) computer adaptive test (CAT) Version 2.0 item bank aids in the evaluation of rotator cuff repair (RCR) rehabilitation by determining when recovery milestones are possible based on the quality of patient responses at certain time points.

Purpose

To assess the time point at which patients with RCR were able to achieve specific functional milestones, determined as positive responses to the 5 most frequently asked items on the PROMIS UE CAT Version 2.0.

Study Design

Case series; Level of evidence, 4.

Methods

The postoperative PROMIS UE CAT Version 2.0 scores of patients who underwent RCR between February 16, 2017, and July 30, 2019, were reviewed with respect to individual PROMIS item, response, and timing of response. A functional milestone was considered achieved if the patient response was "without any difficulty" or "with a little difficulty" to any of the 5 most frequently asked PROMIS items. The percentage of patients in each monthlong postoperative interval who answered with either response was recorded. The logit generalized estimating equations method was used to analyze the association between milestone achievement for each PROMIS item and predictor variables (age, sex, body mass index, smoking status, race, ethnicity, and employment status).

Results

A total of 1131 responses from 371 patients were included. The majority of patients attained milestone achievement on 4 of the 5 most frequently asked PROMIS items at time points ranging from 1 to 5 months postoperatively: "Are you able to carry a shopping bag or briefcase?" (by 1 month), "Are you able to put on and take off a coat or jacket?" (by 3 months), "Are you able to pour liquid from a bottle into a glass?" (by 3 months), and "Are you able to carry a heavy object (over 10 pounds/5 kg)?" (by 5 months). For the item "Are you able to put on a shirt or blouse?", the majority of patients did not achieve the milestone by 1 year.

Conclusion

These findings support the application of PROMIS UE CAT Version 2.0 milestone achievement in the shared decision-making process and postoperative monitoring, as patients can use this information to determine when they can return to certain activities and providers can apply these standards to identify patients needing additional clinical support.

Determining the Time Required to Achieve Clinically Significant Outcomes on the PROMIS Upper Extremity Questionnaire After Arthroscopic Rotator Cuff Repair

Background

Clinically significant outcome (CSO) thresholds for the Patient-Reported Outcome Measurement Information System-Upper Extremity (PROMIS-UE) score have been previously defined after arthroscopic rotator cuff repair (RCR). However, the time required to achieve CSOs for the PROMIS-UE score is unknown.

Purpose

To (1) determine the time required to achieve the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and Patient Acceptable Symptom State (PASS) score thresholds after RCR for the PROMIS-UE questionnaire and (2) identify patient factors associated with earlier or delayed achievement of these clinical benchmarks.

Study Design

Case-control study; Level of evidence, 3.

Methods

A prospectively maintained institutional database was retrospectively reviewed for consecutive patients who underwent RCR between January 2018 and January 2019. Patients were included if they completed the PROMIS-UE questionnaire both preoperatively and at standardized postoperative time intervals: 5 to 7 months (6-month time point), 11 to 13 months (1-year time point), and ≥23 months (2-year time point). Kaplan-Meier survival curves with interval censoring were used to define the cumulative percentage of patients who achieved the MCID, SCB, and PASS. Patient variables associated with earlier or delayed achievement of the MCID, SCB, and PASS were determined using Weibull parametric survival regression analysis.

Results

Included were 105 patients undergoing RCR (age, 57.3 ± 10.3 years; body mass index, 31.5 ± 6.1 kg/m²). By 2-year follow-up, the cumulative percentage of patients achieving the MCID, SCB, and PASS was 86.7%, 76.2%, and 74.3%, respectively. The mean time required to reach the MCID, SCB, and PASS score thresholds was 9.5 ± 3.8, 10.3 ± 4.4, and 9.8 ± 4.6 months, respectively. Factors associated with delayed achievement of CSOs included greater baseline PROMIS-UE score (MCID and SCB) and workers' compensation insurance (PASS). Greater baseline PROMIS-UE scores were associated with earlier achievement of the PASS.

Conclusion

Most patients achieved CSOs for the PROMIS-UE within 12 months of RCR. Patient-specific factors found to be associated with earlier or delayed achievement of CSOs can be used to inform patient discussions on the expected timeline for recovery after RCR.

Long-term functional, psychological, emotional, and social outcomes in pediatric victims of violence

BACKGROUND

To evaluate the long-term functional, psychological, and emotional outcomes in individuals who survived violence-related injuries as children.

METHODS

We retrospectively identified all pediatric patients (age <18y at time of injury) treated for a violent traumatic injury (gun-shot wound, stab, or assault) at our institution (1/2011-12/2020). We then prospectively attempted to contact and survey, via telephone, all patients that had reached adulthood (age ≥18y at time of study) using 7 Patient-Reported Outcomes Measurement Information System (PROMIS) instruments and the Primary Care Post Traumatic Stress Disorder (PTSD) screen.

RESULTS

Of the 270 patients identified, we attempted to contact 218, successfully contacted 68, and 24 participated in the study. Of participants, 15 (62.5%) sustained gunshot wounds, 8 (33.3%) were stabbed, and 1 (4.2%) was assaulted with a median time from injury of 6.7(3.4) years. Based on PROMIS metrics, Global Physical Health (55.0 vs. 50.0, p = 0.013) and Emotional Support (55.4 vs. 50.0, p = 0.004) were better in participants compared to reference populations. However, a disproportionate number of participants reported substance use in the past 30 days (45.8 vs 13.0%; p < 0.001), 41.7% screened positive for PTSD, and 62.5% requested resources and/or referral for medical care.

CONCLUSIONS

Many individuals who survive violent injuries as children continued to experience negative physical and mental outcomes extending into adulthood that required ongoing medical and psychological support. Further resources are needed to better understand the long-term effects of violent injury and to care for the complex needs of this population.

Responsiveness and Minimal Important Change of the PROMIS Pain Interference Item Bank in Patients Presented in Musculoskeletal Practice

We evaluated the responsiveness of the Patient Reported Outcome Information System Pain Interference item bank in patients with musculoskeletal pain by testing predefined hypotheses about the relationship between the change scores on the item bank, change scores on legacy instruments and Global Ratings of Change (GRoC), and we estimated Minimal Important Change (MIC). Patients answered the full Dutch-Flemish V1.1 item bank. From the responses we derived scores for the standard 8-item short form (SF8a) and a CAT-score was simulated. Correlations between the change scores on the item bank, GRoC and legacy instruments were calculated, together with Effect Sizes, Standardized Response Means, and Area Under the Curve. GRoC were used as an anchor for estimating the MIC with (adjusted) predictive modeling. Of 1,677 patients answering baseline questionnaires 960 completed follow-up questionnaires at 3 months. The item bank correlated moderately high with the GRoC (Spearman's rho 0.63) and with the legacy instruments (Pearson's R ranging from .45 to .68). It showed a high ES (.97) and Standardized Response Means (.71), and could distinguish well between improved and not improved patients based on the GRoC (Area Under the Curve .77). Comparable results were found for the derived SF8a and CAT-scores. The MIC was estimated to be 3.2 (CI 2.6-3.7) T-score points. PERSPECTIVE: Our study supports the responsiveness of the PROMIS-PI item bank in patients with musculoskeletal complaints. Almost all predefined hypotheses were met (94%). The PROMIS-PI item bank correlated well with several legacy instruments which supports generic use of the item bank. MIC for PROMIS-PI was estimated to be 3.2 T-score points.

Compression Screw Fixation for Pediatric Olecranon Fractures

BACKGROUND

Pediatric olecranon fractures can be treated with several methods of fixation. Though postoperative outcomes of various fixation techniques, including cannulated intramedullary screws, have been described in adults, functional and radiographic outcomes of screw fixation in pediatric patients are unclear. In this study, we assessed clinical, radiographic, functional, and patient-reported outcomes of pediatric olecranon fractures treated with compression screw fixation.

METHODS

We retrospectively identified 37 patients aged 16 years or younger with a total of 40 olecranon fractures treated with screw fixation at our level-1 trauma center between April 2005 and April 2022. From medical records, we extracted data on demographic characteristics, time to radiographic union, range of elbow motion at final follow-up, and complications during the follow-up period. Patient-reported outcomes were evaluated using the Quick Disabilities of the Arm, Shoulder, and Hand and Patient-Reported Outcomes Measurement Information System Pediatric Upper Extremity Short Form 8a measures.

RESULTS

There were no malunions or nonunions at the final mean follow-up of 140 days (range, 26 to 614 d). Four patients had implant failure (11%), of whom 3 experienced fracture union with no loss of fixation or need for revision surgery. One patient underwent a revision for fracture malreduction. Screw prominence was documented in 1 patient. Instrumentation was removed at our institution for 33 of 40 fractures. Mean time to radiographic union was 53 days (range, 20 to 168 d). Postoperative range of motion at the most recent follow-up visit showed a mean extension deficit of 6 degrees (range, 0-30 degrees) and mean flexion of 134 degrees (range, 60-150 degrees). At the final follow-up, the mean (±SD) Quick Disabilities of the Arm, Shoulder, and Hand score was 4.2±8.0, and the mean Patient-Reported Outcomes Measurement Information System score was 37±1.5, indicating good function and patient satisfaction.

CONCLUSIONS

All 37 patients in our series had excellent radiographic, functional, and patient-reported outcomes after screw fixation. We observed no cases of nonunion or malunion, growth disturbance, or refracture. These results suggest that screw fixation is a safe and effective option for pediatric olecranon fractures.

Performance and responsiveness to change of PROMIS UE in patients undergoing total shoulder arthroplasty

The Patient-Reported Outcomes Measurement Information System Upper Extremity Computer Adaptive Test (PROMIS UE CAT) is a newer patient-reported outcome measure for upper extremity physical function. To date, no longitudinal study exists assessing PROMIS UE CAT responsiveness in patients undergoing shoulder arthroplasty. The purpose of this prospective longitudinal study is to report PROMIS UE CAT responsiveness to change and correlation to legacy instruments in patients undergoing total shoulder arthroplasty (TSA). Ninety-six patients (97 shoulders) undergoing TSA completed the PROMIS UE, Oxford Shoulder Score (OSS), American Shoulder and Elbow Surgeons (ASES), and Simple Shoulder Test (SST) preoperatively and postoperatively at 6 weeks, 12 weeks, and after 6 months. Spearman's correlation coefficients (r) were calculated between PROMIS UE and other scores at each time-point. Responsiveness to change was assessed using the effect size (Cohen's d) and standardized response mean compared with the preoperative time-point. Floor and ceiling effects were also assessed. PROMIS UE CAT demonstrated positive responsiveness at all time-points after TSA. It demonstrated excellent correlation (range: 0.68-0.84) with ASES, SST, and OSS at all postoperative time-points, but the correlation was weaker (r < 0.6, except OSS) preoperatively. Only OSS and SST showed ceiling effects at the 6-12-month time-point (16.8% and 18.2%, respectively). PROMIS UE CAT responsiveness to change and strength of correlation with legacy instruments improves with time elapsed after TSA. Further quantification of meaningful responsiveness to change will require estimation of the minimal clinically important difference and substantial clinical benefit for PROMIS UE CAT.

Upper Quadrant Pain and Disability Associated with a Cross-Sectional Area of Deep and Superficial Neck Muscles: A Computed Tomography Study

STUDY DESIGN

An analytical cross-sectional computed tomography (CT) study.

OBJECTIVE

To investigate the association of the cross-sectional area (CSA) and density of neck muscles (sternocleidomastoid, upper trapezius, levator scapulae, anterior scalene, longus coli, longus capitis) with upper quadrant pain and disability.

SUMMARY OF BACKGROUND DATA

Neck pain, a common condition, causes substantial disability to individuals. The deep cervical flexor muscles are impaired in persons with neck pain. These muscles play a greater role in maintaining stable head postures, whereas, superficial muscles are responsible for peak exertions and reinforcing spinal stability at terminal head postures.

METHODS

Two hundred thirty consecutive individuals suffering from neck pain were referred to CT scans; 124/230 complied with the inclusion and exclusion criteria. Subjects were interviewed and the measurements of the CSA and muscle density were extracted from the scans.

RESULTS

Muscles associated with quick disability of the arms, shoulders, and hand questionnaire (QDASH) were the lateral posterior group (LPG) CSA C3-C4 on the right side (beta = -0.31, P = 0.029); the sternocleidomastoid (SCM) CSA C3-C4 on the left side (beta = 0.29, P = 0.031); the LPG CSA C3-C4 on the left side (beta = -0.49, P = 0.000); the LCM CSA C5-C6 on the right side (beta = -0.19, P = 0.049); the LPG CSA C5-C6 on the right side (beta = -0.36, P = 0.012); and the LPG CSA C5-C6 on the left side (beta = -0.42, P = 0.002). Further analyses with radiculopathy acting as an augmenting/enhancing variable (moderator), showed an increase in the model strength (r2 = 0.25) with a stronger prediction of pain and disability. Muscle measurements did not predict neck disability index (NDI) scores.

CONCLUSION

By using an accurate measuring tool, we found an association of the deep and superficial neck muscles' CSA with upper extremities' pain and disability. When performing manual work, a special load is placed on the shoulders and neck muscles. Future research should focus on examining the effectiveness of exercise-type intervention programs to strengthen the deep neck and upper extremities' muscles in order to prevent muscle fatigue.Level of Evidence: 2.

Are Patient Reported Outcome Measurement Information System scales responsive in patients attending physical therapy with foot and ankle diagnoses?

BACKGROUND

Patient-reported outcomes (PROs) have been used to provide insight into the patient experience while uncovering an opportunity to improve patient care. Current studies document responsiveness of outcomes using the Patient Reported Outcome Measurement Information System (PROMIS) for a variety of orthopedic problems but are not specific to a physical therapy interval of care.

PURPOSE

The main purpose of this study was to examine responsiveness of the PROMIS Physical Function (PF) and Pain Interference (PI) scales across an interval of care for physical therapy in patients with foot and ankle conditions.

METHODS

Adult records (299 records, averaged 45.1 ± 15.4 years; 61% female) were assessed. Comparisons between pre- and post-physical therapy intervals of care were evaluated using a repeated-measures ANOVA, and the effect size was reported using Cohen's d.

RESULTS

PROMIS PF scores significantly improved from 38.5 ± 8.8 to 45.2 ± 9.1 (6.6; p < .001; Cohen's d = 1.0). PROMIS PI scores significantly improved from 56.8 ± 8.8 to 53.0 ± 9.8 (-3.8; p < .001; Cohen's d = 0.52).

CONCLUSIONS

The person-centered PROMIS PF and PI outcome measures were responsive to change following an interval of care in physical therapy for a large sample of orthopedic patients with foot and ankle diagnoses. The magnitude of change was dependent on starting score and diagnosis.

Preoperative Patient-Reported Outcomes Measurement Information System Computerized Adaptive Testing (PROMIS CAT) Scores Predict Achievement of Minimum Clinically Important Difference Following Anterior Cruciate Ligament Reconstruction Using an Anchor-Based Methodology

PURPOSE

To determine the change in Patient-Reported Outcomes Measurement Information System Computerized Adaptive Testing (PROMIS CAT) scores for physical function, pain interference, and depression that constitute minimum clinically important difference (MCID) using an anchor-based technique and to identify pre-operative clinical thresholds in anchor-based MCID that predict likelihood of achieving MCID following anterior cruciate ligament (ACL) reconstruction.

METHODS

Adult patients aged 18 years or older undergoing ACL reconstruction that completed both preoperative and postoperative PROMIS CAT assessments and an anchor-based questionnaire were identified over a 23-month period. Anchor-based MCID was determined for PROMIS CAT forms for physical function (PROMIS PF CAT), pain interference (PROMIS PI CAT), and depression (PROMIS D CAT).

RESULTS

A total of 137 patients were included for statistical analysis, with pre-operative PROMIS CAT forms completed 27.9 ± 31.2 days before surgery and 492.5 ± 219.9 days postoperatively on average. Statistically significant improvements were observed for all PROMIS CAT domains. PROMIS PF CAT improved from 39.5 ± 8.2 to 55.0 ± 9.7 (P < .0005), PROMIS PI CAT from 59.8 ± 7.2 to 48.2 ± 8.3 (P < .0005), and PROMIS D CAT from 47.9 ± 8.8 to 41.5 ± 8.6 (P < .0005). Anchor-based MCID for each PROMIS CAT form was calculated to be +4.5, -5.4, and -4.1 for PROMIS PF CAT, PROMIS PI CAT, and PROMIS D CAT, respectively. Mean difference between preoperative and postoperative PROMIS CAT scores exceeded MCID for all domains. The percentage of patients achieving MCID for PROMIS PF CAT, PROMIS PI CAT, and PROMIS D CAT was 85%, 72%, and 55%, respectively. After introduction of 95% specificity cutoffs, the percentage of patients achieving MCID for PROMIS PF CAT, PROMIS PI CAT, and PROMIS D CAT increased to 100% (<35.6 cutoff score), 92% (>65.7 cutoff score), and 83% (>57.5 cutoff score), respectively.

CONCLUSIONS

According to anchor-based analysis of PROMIS CAT MCID, ACL reconstruction is effective in improving physical function, pain interference, and depression symptoms. In addition, preoperative PROMIS CAT scores can predict the likelihood of achieving MCID postoperatively.

Establishing the Minimal Clinically Important Difference for the PROMIS Upper Extremity Computer Adaptive Test Version 2.0 in a Nonshoulder Hand and Upper Extremity Population

PURPOSE

Our primary purpose was to calculate the minimal clinically important difference (MCID) for the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Computer Adaptive Test (CAT) version 2.0 (v2.0) for a nonshoulder hand and upper extremity population. Secondarily, we calculated the PROMIS Physical Function (PF) CAT v2.0 and the abbreviated version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) MCID.

METHODS

Adult patients treated by 1 of 5 fellowship-trained hand surgeons between March 2015 and September 2019 at an academic tertiary institution were identified. The PROMIS UE CAT v2.0, PROMIS PF CAT v2.0, and QuickDASH were collected via tablet computer. Inclusion required response to at least 1 of the instruments at both baseline and follow-up (6 ± 4 weeks), and a response to the anchor question: "Compared to your first evaluation at the University Orthopaedic Center, how would you describe your physical function level now?" An additional anchor question assessing treatment-related improvement was also asked. The MCID was calculated using an anchor-based approach using the mean change difference between groups reporting no change and slight change for both anchor questions, and with the 1/2 SD method.

RESULTS

Of 2,106 participants, mean age was 48 ± 17 years, 53% were female, and 53% were recovering from surgery. Of these patients, 381 completed the PROMISE UE CAT v2.0, 497 completed the PROMIS PF CAT v2.0, and 2,018 completed the QuickDASH. The score change between baseline and follow-up was significantly different between anchor groups for both anchor-based MCID calculations. Anchor-based MCID values were 3.0 to 4.0 for the UE CAT, 2.1 to 3.6 for the PF CAT, and 10.3 for the QuickDASH. The MCID values per the 1/2 SD method were 4.1, 4.1, and 10.2, respectively.

CONCLUSIONS

We propose MCID ranges of 3.0 to 4.1 for the PROMIS UE CAT v2.0, and 2.1 to 4.1 for the PROMIS PF CAT v2.0. The observed QuickDASH MCID values (10.2-10.3) are within the range of previously published values.

CLINICAL RELEVANCE

These MCID estimates will aid in interpreting clinical outcomes and in powering clinical studies.

Do clinical criteria based on PROMIS outcomes identify acceptable symptoms and function for patients with musculoskeletal problems

BACKGROUND

Understanding how symptoms influence patient judgements of their health informs providers where to direct care. Patient reported physical outcomes (physical function, pain interference) and self-efficacy of symptom management (SEsm)) predict a patient's health state (i.e. patient acceptable symptom state (PASS)). However, it's unclear if therapist should consider a psychological outcome like SEsm separately or combine this outcome with other physical outcomes for clinical decisions.

OBJECTIVE

To determine if patient reported outcome information system (PROMIS) SEsm scale when combined with PROMIS physical function or pain interference is able to accurately predict a patient's health state defined by PASS.

METHODS

One hundred ninety-six patients (initial sample (n = 94) and separate sample (n = 102)) were surveyed by phone after care for a musculoskeletal problem. Patients completed PASS, PROMIS physical function, pain interference and SEsm outcomes. Logistic regression was used to estimate odds ratios (OR) for determining PASS in the initial sample. Criteria for determining PASS developed from the regression analysis were applied to a separate sample to assess accuracy. Accuracy for PASS status were also assessed at 1-7 days and 45-60 days.

RESULTS

Three combinations including SEsm/pain interference and SEsm/physical function showed significant OR's (<0.1) and varied from 2.5 to 4.2 for predicting PASS status. Criteria to predict PASS in the separate sample at 1-7 days and 45-60 days showed accuracies from 74.5% to 83.6%.

CONCLUSION

This study demonstrates that utilizing SEsm in combination with common physical outcomes used to assess patients with musculoskeletal diagnoses improves prediction of a patient's acceptable level of symptoms and activity.

Establishing Age-calibrated Normative PROMIS Scores for Hand and Upper Extremity Clinic

The purpose of our study is to investigate differences in normative PROMIS upper extremity function (PROMIS-UE), physical function (PROMIS-PF), and pain interference (PROMIS-PI) scores across age cohorts in individuals without upper extremity disability.

Minimal Clinically Important Difference of the PROMIS Upper-Extremity Computer Adaptive Test and QuickDASH for Ligament Reconstruction Tendon Interposition Patients

PURPOSE

To calculate the minimal clinically important difference (MCID) of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test (UE CAT) and Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) for ligament reconstruction tendon interposition (LRTI) patients.

METHODS

Adult patients treated with LRTI for trapeziometacarpal OA by fellowship-trained hand surgeons between December 2014 and February 2018 at an academic tertiary institution were included. Outcomes were prospectively collected at each visit by tablet computer, including the QuickDASH, PROMIS UE, Pain Interference, Depression, and Anxiety CATs. Inclusion required a response to the anchor question "How much relief and/or improvement do you feel you have experienced as a result of your treatment?" on a 6-option Likert scale, as well as preoperative (≤120 days before surgery) and follow-up (2-26 weeks) outcomes. We calculated MCID both by an anchor-based approach using the mean score of the minimal change group, and with the 0.5 SD method.

RESULTS

Of 145 included participants, mean age was 63 ± 8 years and 74% were female. Anchor-based MCID estimates for the total cohort were 4.2 for the PROMIS UE CAT and 8.8 for the QuickDASH. The MCID estimates using the 0.5 SD method were 4.8 and 11.7, respectively.

CONCLUSIONS

We propose MCID values of 4.2 to 4.8 for the PROMIS UE CAT and 8.8 to 11.7 for the QuickDASH when powering clinical studies or when assessing improvement among a cohort of patients who have undergone LRTI surgery.

CLINICAL RELEVANCE

Minimal clinically important difference estimates are helpful when interpreting clinical outcomes after LRTI and for powering prospective trials.

Outcome Measurement for Distal Radius Fractures

Distal radius fractures (DRFs) are among the most common upper extremity injuries. Multiple medical conditions now are evaluated by standardized outcome sets that enable comparability. Recent international working groups have provided consensus statements for outcomes measurement after DRFs. These statements emphasized the growing importance of patient-reported outcome measures as well as traditional measures, including pain assessment, radiographic alignment, performance, and assessment of complications. A standardized instrument and timeline for measuring outcomes following DRFs offers clinicians, researchers, and health care economists a powerful tool. This article reviews the current evidence and provides recommendations for a DRF standardized outcome set.

Targeted Muscle Reinnervation at the Time of Upper-Extremity Amputation for the Treatment of Pain Severity and Symptoms

PURPOSE

Targeted muscle reinnervation (TMR) is a technique for the management of peripheral nerves in amputation. Phantom limb pain (PLP) and residual limb pain (RLP) trouble many patients after amputation, and TMR has been shown to reduce this pain when performed after the initial amputation. We hypothesize that TMR at the time of amputation may improve pain for patients after major upper-extremity amputation.

METHODS

We conducted a retrospective review of patients who underwent major upper-extremity amputation with TMR performed at the time of the index amputation (early TMR). Phantom limb pain and RLP intensity and associated symptoms were assessed using the numeric rating scale (NRS), the Patient-Reported Outcome Measurement Information System (PROMIS) Pain Intensity Short-Form 3a, the Pain Behavior Short-Form 7a, and the Pain Interference Short-Form 8a. The TMR cohort was compared with benchmarked data from a sample of upper-extremity amputees.

RESULTS

Sixteen patients underwent early TMR and were compared with 55 benchmark patients. More than half of early TMR patients were without PLP (62%) compared with 24% of controls. Furthermore, half of all patients were free of RLP compared with 36% of controls. The median PROMIS PLP intensity score for the general sample was 47 versus 38 in the early TMR sample. Patients who underwent early TMR reported reduced pain behaviors and interference specific to PLP (50 vs 53 and 41 vs 50, respectively). The PROMIS RLP intensity score was lower in patients with early TMR (36 vs 47).

CONCLUSIONS

This study demonstrates that early TMR is a promising strategy for treating pain and improving the quality of life in the upper-extremity amputee. Early TMR may preclude the need for additional surgery and represents an important technique for peripheral nerve surgery.

Performance of PROMIS Physical Function, Pain Interference, and Depression Computer Adaptive Tests Instruments in Patients Undergoing Meniscal Surgery

Purpose

To compare the performance of the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF), pain interference (PIF), and depression computer adaptive tests (CAT) relative to legacy instruments in patients undergoing meniscal surgery.

Methods

Patients scheduled to undergo meniscal surgery completed legacy knee function PROMs (International Knee Documentation Committee [IKDC], Knee Injury and Osteoarthritis Outcome Score [KOOS] subscores), Marx Activity Rating Scale (MARS), Veterans-Rand 12 (VR12), Short Form 12 (SF12), and the Brief Resilience Scale (BRS) alongside PROMIS PF, PIF, and Depression preoperatively. Spearman rank correlations were calculated, and score distributions were examined for floor and ceiling effects.

Results

152 patients (46.6 ± 14.9 years, 67.1% male) completed PROMs for appropriate inclusion. PROMIS PF yielded high-moderate to high correlations with the IKDC and KOOS subscales (r = 0.61 to 0.73), demonstrating similar performance to the IKDC. PROMIS PIF demonstrated moderately high-moderate to high correlations with the IKDC, KOOS subscales, VR-12 Physical Component Score (PCS), and SF12 PCS (r = 0.62 to 0.71), performing comparably to KOOS Pain (r = 0.55 to 0.92). PROMIS Depression demonstrated moderate to high-moderate correlations with the mental health legacies (r = 0.46 to 0.66). Significant ceiling effects were observed for MARS (n = 29, 18.8%), and significant floor effects were exhibited by PROMIS Depression (n = 38, 25%) and MARS (n = 27, 17.6%).

Conclusion

The PROMIS PF, PIF CAT, and Depression instruments exhibit comparable performance profiles relative to legacy knee PROMs. PROMIS PF and PIF demonstrated no floor and ceiling effects, whereas PROMIS Depression exhibited a significant relative floor effect. PROMIS PF and PIF may be appropriately used to establish functional baselines preoperatively.

Understanding PROMIS

Patient reported outcomes (PROs) are becoming increasingly emphasized in health care. Some medical and orthopedic specialties have 1 or 2 primary PROs that are used across the discipline, whereas hand surgery has multiple PROs. The multitude of PROs gives hand surgeons flexibility because each provides slightly different information, but the number of options can present a daunting task when choosing which to use. The latest generation of PROs leverages computer adaptive testing and includes assessments of physical, mental, and social health. The Patient-Reported Outcomes Measurement Information System was funded by the National Institutes of Health to include a comprehensive set of health instruments that are not disease-specific; it has undergone several forms of validation and has been found to be comparable across medical specialties. This article discusses the details of the Patient-Reported Outcomes Measurement Information System, how it compares with other outcomes instruments, and how it can be used in practice.

Single Assessment Numeric Evaluation (SANE) in Hand Surgery: Does a One-Question Outcome Instrument Compare Favorably?

PURPOSE

Patient-reported outcome measures are increasingly used to measure patient status, impairments, and disability, but often require lengthy surveys and place a considerable burden on patients. We hypothesized that the Single Assessment Numeric Evaluation (SANE), composed of a single question, would be a valid and responsive instrument to provide a global assessment of hand function.

METHODS

The SANE, Patient-Reported Outcomes Measurement Information System-Upper Extremity (PROMIS-UE), and Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) data are routinely collected electronically in our hand and upper-extremity center. To identify our cohort, we used Current Procedural Terminology codes to query our electronic medical record research data repository for the 7 most common hand surgery procedures performed over 2 years from December 2016 to 2018. These procedures included carpal tunnel release, trigger finger release, thumb carpometacarpal arthroplasty, wrist arthroscopy, distal radius fracture fixation, first dorsal compartment release, and cubital tunnel release. Patients undergoing a single isolated procedure with questionnaires obtained in the preoperative and/or postoperative period were included in the analysis. Convergent validity, coverage, and responsiveness for each instrument were assessed.

RESULTS

We identified 214 patients for inclusion. The SANE score had a moderate to strong correlation with the QuickDASH and PROMIS-UE. Floor and ceiling effects for the SANE were less than 10% at baseline and follow-up. Overall, the QuickDASH was the most responsive, followed by SANE and PROMIS-UE; all 3 instruments exceeded the acceptable thresholds for responsiveness and demonstrated significant changes before to after surgery. Responsiveness of the SANE varied by procedure and was acceptable for carpal tunnel release, carpometacarpal arthroplasty, wrist arthroscopy, and trigger finger release.

CONCLUSIONS

The single-item SANE is a reasonable measure of global function in patients undergoing common hand procedures and demonstrates psychometric properties comparable to those of the PROMIS-UE and QuickDASH outcome scores.

CLINICAL RELEVANCE

The SANE score is a reasonable outcome measure of global hand function that may have utility in demonstrating response to treatment in a practice setting and may provide a useful adjunct to multiple-item measures in clinical research 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.

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.

Responsiveness of the PROMIS and its Concurrent Validity with Other Region- and Condition-specific PROMs in Patients Undergoing Carpal Tunnel Release

BACKGROUND

The Patient-reported Outcome Measurement Information System (PROMIS) continues to be an important universal patient-reported outcomes measure (PROM) in orthopaedic surgery. However, there is concern about the performance of the PROMIS as a general health questionnaire in hand surgery compared with the performance of region- and condition-specific PROMs such as the Michigan Hand Questionnaire (MHQ) and the Boston Carpal Tunnel Questionnaire (BCTQ), respectively. To ensure that PROMIS domains capture patient-reported outcomes to the same degree as region- and condition-specific PROMs do, comparing PROM performance is necessary.

QUESTIONS/PURPOSES

(1) Which PROMs demonstrate high responsiveness among patients undergoing carpal tunnel release (CTR)? (2) Which of the PROMIS domains (Physical Function [PF], Upper Extremity [UE], and Pain Interference [PI]) demonstrate concurrent validity with the HHQ and BCTQ domains?

METHODS

In this prospective study, between November 2014 and October 2016, patients with carpal tunnel syndrome visiting a single surgeon who elected to undergo CTR completed the BCTQ, MHQ, and PROMIS UE, PF, and PI domains at each visit. A total of 101 patients agreed to participate. Of these, 31 patients (31%) did not return for a followup visit at least 6 weeks after CTR and were excluded, leaving a final sample of 70 patients (69%). We compared the PROMIS against region- and condition-specific PROMs in terms of responsiveness and concurrent validity. Responsiveness was determined using Cohen's d or the effect-size index (ESI). The larger the absolute value of the ESI, the greater the effect size. Using the ESI allows surgeons to better quantify the impact of CTR, with a medium ESI (that is, 0.5) representing a visible clinical change to a careful observer. Concurrent validity was determined using Spearman's correlation coefficient with correlation strengths categorized as excellent (> 0.7), excellent-good (0.61-0.70), good (0.4-0.6), and poor (< 0.4). Significance was set a priori at p < 0.05.

RESULTS

Among PROMIS domains, the PI demonstrated the best responsiveness (ESI = 0.74; 95% CI, 0.39-1.08), followed by the UE (ESI = -0.66; 95% CI, -1.00 to -0.31). For the MHQ, the Satisfaction domain had the largest effect size (ESI = -1.48; 95% CI, -1.85 to -1.09), while for the BCTQ, the Symptom Severity domain had the best responsiveness (ESI = 1.54; 95% CI, 1.14-1.91). The PROMIS UE and PI domains demonstrated excellent-good to excellent correlations to the total MHQ and BCTQ-Functional Status scores (preoperative UE to MHQ: ρ = 0.68; PI to MHQ: ρ = 0.74; UE to BCTQ-Functional Status: ρ = 0.74; PI to BCTQ-Functional Status: ρ = 0.67; all p < 0.001), while the PROMIS PF demonstrated poor correlations with the same domains (preoperative PF to MHQ; ρ = 0.33; UE to BCTQ-Functional Status: ρ = 0.39; both p < 0.01).

CONCLUSIONS

The PROMIS UE and PI domains demonstrated slightly worse responsiveness than the MHQ and BCTQ domains that was nonetheless acceptable. The PROMIS PF domain was unresponsive. All three PROMIS domains correlated with the MHQ and BCTQ, but the PROMIS UE and PI domains had notably stronger correlations to the MHQ and BCTQ domains than the PF domain did. We feel that the PROMIS UE and PI can be used to evaluate the clinical outcomes of patients undergoing CTR, while also providing more robust insight into overall health status because they are general PROMs. However, we do not recommend the PROMIS PF for evaluating patients undergoing CTR.

The Impact of Workers' Compensation on Patient-Reported Outcomes Measurement Information System Upper Extremity and Legacy Outcome Measures in Patients Undergoing Arthroscopic Rotator Cuff Repair

PURPOSE

To examine the preoperative performance of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Computer Adaptive Test (CAT) with respect to legacy scores in patients receiving rotator cuff repair (RCR). In addition, to define the impact of Workers' Compensation (WC) status on both performance and floor and ceiling effects.

METHODS

The PROMIS UE CAT was administered preoperatively alongside legacy patient-reported outcome measures (PROMs) to patients undergoing isolated arthroscopic RCR from November 2017 to September 2018. Performance was assessed using Spearman correlation coefficients, and floor and ceiling effects were examined.

RESULTS

One hundred twenty-two patients (WC, n = 32; non-WC, n = 90; 62.3% male, 53.6 ± 11.5 years) were included. PROMs assessing physical function (r = 0.41-0.77) correlated more strongly to the PROMIS UE CAT than did multidomain or mental health PROMs (r = 0.25-0.61). In WC patients, the PROMIS UE CAT demonstrated diminished correlative strength relative to shoulder function PROMs. WC patients also demonstrated relative floor effects for Single Assessment Numerical Evaluation (SANE; 18.8%) and Constant-Murley (15.6%) and relative ceiling effects for the Brief Resilience Scale (53.1%), Short Form 12 Mental Component Score (50%), and Veterans Rand 12 Mental Component Score (53.1%) and were more likely to report the minimum SANE score (P < .01) and the maximum Brief Resilience Scale score (P < .01). No absolute or relative floor/ceiling effects for the PROMIS UE CAT were found.

CONCLUSIONS

Compared with a non-WC cohort, WC patients have significantly lower preoperative PROMIS UE CAT scores, are more likely to report the absolute minimum and maximum scores for various PROMs, and demonstrated relative floor and ceiling effects for PROMs assessing mental health. The absence of significant floor/ceiling effects for the PROMIS UE CAT may suggest improved outcome discrimination and may support the adoption of PROMIS UE for the assessment of functional status in WC patients with rotator cuff pathology.

Minimal Clinically Important Differences for PROMIS Physical Function, Upper Extremity, and Pain Interference in Carpal Tunnel Release Using Region- and Condition-Specific PROM Tools

PURPOSE

Uncertainty exists about what change in Patient-Reported Outcomes Measurement Information System (PROMIS) scores represents a clinically relevant improvement (minimal clinically important difference [MCID]) in hand surgery care. Using a region-specific patient-reported outcome measure (PROM) (Michigan Hand Question [MHQ]) and a condition-specific PROM (Boston Carpal Tunnel Questionnaire [BCTQ]), MCID values were determined for PROMIS Physical Function (PF), Upper Extremity (UE), and Pain Interference (PI) computerized adaptive testing among patients undergoing carpal tunnel release (CTR).

METHODS

Patients undergoing CTR with a single surgeon from November 2014 to April 2017 were asked to complete the BCTQ, MHQ, and PROMIS PF, UE, and PI at each visit. Patients who had completed questionnaires both at a preoperative and either a 6-week or a 3-month postoperative visit were included. The PROMIS PF, UE, and PI MCID values were calculated using previously determined MCID estimates in the literature with both region- (ie, MHQ) and condition-specific (ie, BCTQ) PROM anchors. The PROMIS domain MCID estimates were also determined using the distribution-based method.

RESULTS

A total of 70 patients fit our inclusion criteria. Using MHQ Function and Pain, PROMIS UE, PF, and PI MCIDs were 6.3, 1.8, and -8.9, respectively. Using the average of the 2 BCTQ domains, PROMIS UE, PF, and PI MCIDs were 8.0, 2.8, and -9.7, respectively. Using the distribution-based method, PROMIS UE, PF, and PI MCIDs were 4.2, 2.7, and -4.1, respectively.

CONCLUSIONS

Using region- and condition-specific PROMs, we were able to provide MCID estimates of PROMIS UE, PF, and PI for patients undergoing CTR.

CLINICAL RELEVANCE

Estimating PROMIS UE, PF, and PI MCIDs in CTR using validated region- and condition-specific PROMs provides hand surgeons a way to evaluate CTR outcomes not previously described in the literature. Surgeons should understand that these values are only estimates and future work is needed to verify whether they reflect clinical improvement.

Evaluation of Version 2.0 of the PROMIS Upper Extremity Computer Adaptive Test in Nonshoulder Upper Extremity Patients

PURPOSE

The Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test (UE CAT) was recently updated to version 2.0 (v2.0). We hypothesized that the PROMIS UE CAT v2.0 would exhibit improved performance characteristics compared with the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) when administered to a nonshoulder upper extremity patient population.

METHODS

The UE CAT v2.0, Physical Function (PF) CAT v2.0, and the QuickDASH were each prospectively administered via tablet computer to all patients presenting to a tertiary hand and upper extremity clinic between April 2017 and October 2017. Patient responses were analyzed, and the mean, range, floor and ceiling effect, and correlations between instruments were calculated.

RESULTS

Among 825 patients, the mean UE CAT v2.0 score was 38.3 (SD 10.7) with a range of 15 to 61 and interquartile range of 15.4. The UE CAT v2.0 had a strong correlation with the QuickDASH (r = -0.749) and the PF CAT v2.0 (r = 0.719). No patient scored between 56 and 60, indicating a gap in scoring in that range. The UE CAT v2.0 demonstrated a floor effect of 1%, a ceiling effect of 6.9%, and a high internal consistency with a Cronbach alpha of 0.99.

CONCLUSIONS

The PROMIS UE CAT v2.0 demonstrated improved ceiling effects, range, and a decreased gap in scoring compared with prior versions. Limitations of the PROMIS UE CAT v2.0 are still present, but updates have led to an incremental improvement over prior versions, demonstrating the ability to influence PROMIS instrument performance through upgrades.

CLINICAL RELEVANCE

The updated PROMIS UE CAT v2.0 still demonstrates a ceiling effect and gap in scores at the upper end of the instrument, both of which may limit discrimination between different levels of upper extremity function for high-functioning patients.

Item reduction of the patient-rated wrist evaluation using decision tree modelling

Background: The aim of this study is to assess the viability of a decision tree version of an often used questionnaire to measure wrist pain and disability, the Patient Rated Wrist Evaluation.Methods: Patient Rated Wrist Evaluation scores were collected from a cohort of 10394 patients who are part of a routine outcome measurement system. A decision tree version of the Patient Rated Wrist Evaluation (PRWE) was created. The intraclass correlation was used to evaluate the inter-version reliability between the original PRWE and the decision tree version.Results: The decision tree reduced the number of questions from 5 to 3 for the pain subscale, and from 10 to 3 for the disability subscale. The intraclass correlation between the original PRWE and the decision tree version was 0.97. The mean difference between the Patient Rated Wrist Evaluation and the decision tree Patient Rated Wrist Evaluation total sumscore was 0.35 (95% CI -9.92-10.62).Conclusions: We found that the decision tree was successful at reducing the items of the Patient Rated Wrist Evaluation from fifteen to only six questions with very high similarity to the scores of the full questionnaire.Implications for rehabilitationThe Patient Rated Wrist Evaluation can reliably be used with 6 instead of 15 questions.Decision trees are useful statistical tools to shorten lengthy questionnaires, especially when large amounts of data are available.Having a shortened Patient Rated Wrist Evaluation saves patients and clinicians time in answering this specific questionnaire.
