Measuring outcomes in hand surgery

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.

Establishing the Patient Acceptable Symptom State in a Nonshoulder Hand and Upper Extremity Population for the QuickDASH and PROMIS UE Computer Adaptive Tests

PURPOSE

It is unclear what score thresholds on patient-reported outcomes instruments reflect an acceptable level of upper extremity (UE) function from the perspective of patients undergoing hand surgery. The purpose of this study was to calculate the patient acceptable symptom state (PASS) for the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Patient-Reported Outcomes Measurement Information System (PROMIS) UE Computer Adaptive Test (CAT), version 2.0, in a population who underwent hand surgery.

METHODS

Adult patients who underwent hand surgery between February 2019 and December 2019 at a single academic tertiary institution were identified. QuickDASH and PROMIS UE CAT version 2.0 scores were collected 1 year after surgery, as were separate symptom- and function-specific anchor questions that queried the acceptability of patients' current state. Threshold values predictive of a patient reporting an acceptable symptom state (PASS[+]) were calculated for both instruments using the 75th percentile score for patients in the PASS(+) group and the Youden Index as determined by receiver operating curve (ROC) analysis.

RESULTS

A total of 222 patients were included. QuickDASH and PROMIS UE CAT scores differed significantly between the PASS(+) and PASS(-) groups. The 75th percentile method yielded PASS values of <16 for the QuickDASH and >43 for the PROMIS UE CAT for both anchor questions. The ROC analysis yielded PASS estimates of <15.9 to <20.5 for the QuickDASH and >38.1 to >46.2 for the PROMIS UE CAT, with ranges calculated from differing threshold values for each of the 2 anchor questions. The ROC-based estimates demonstrated high levels of model discrimination (area under the curve ≥ 0.80).

CONCLUSIONS

We propose PASS estimates obtained using the 75th percentile and ROC methods.

CLINICAL RELEVANCE

Specifically, PASS values in the range of 15.9-20.5 for the QuickDASH and 38.1-46.2 for the PROMIS UE CAT version 2.0 should be used when interpreting outcomes at a population level.

Evaluating Factors Associated With Patient-Perceived Applicability of the QuickDASH Survey in Reflecting Their Goals of Care Prior to Hand Surgery

PURPOSE

Patient-reported outcome measures intend to capture patients' perspectives on their health status. However, the patient-perceived applicability of many of these patient-reported outcome measures is unknown. We hypothesized that patients experiencing greater upper extremity disability and greater pain interference would be more likely to report that the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH) survey content is responsive to their daily lives and goals in seeking surgical care.

METHODS

Adult preoperative hand surgery patients at a single tertiary academic center were recruited prospectively. QuickDASH, Patient-Reported Outcomes Measurement Information System Pain Interference computerized-adaptive-testing, and the Godin Leisure-Time Exercise Questionnaire (GLTEQ)-a validated adult physical activity level metric-data were collected. The following two Likert response questions were also asked: question (1) "How applicable is the above questionnaire to your treatment goals for your upper extremity condition?" and question (2) "How applicable is the overall questionnaire to your daily life?" Multivariable binary logistic regression was performed to define the factors associated with patients reporting that the survey was "very applicable."

RESULTS

Of the 133 included patients, the mean age was 49 ± 18 years, 40% were women, and the mean GLTEQ score was 54.1 ± 5.5 (consistent with a high level of activity). For questions 1 and 2, 32% and 29% of the patients reported that QuickDASH was "very applicable," respectively. The multivariable model demonstrated that for every 10-point increase in QuickDASH, there was a 45% to 49% greater odds of respondents reporting that the survey was "very applicable," and for every 5-point increase in pain interference computerized-adaptive-testing, the odds increased by 55% to 70%. No association with GLTEQ was observed.

CONCLUSIONS

Patients with greater upper extremity disability and pain interference were more likely to find the QuickDASH content to be applicable to their daily lives and goals in seeking surgical care.

CLINICAL RELEVANCE

These findings suggest that QuickDASH may not be an optimal instrument when evaluating upper extremity function in cohorts with mild disability and low pain interference.

Preoperative Factors Associated With Worse PROMIS Pain Interference 2 Years After Hand and Wrist Surgery

BACKGROUND

The purpose of this study was to identify preoperative factors associated with worse postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference (PI) scores 2 years after hand and wrist surgery. We hypothesized that older age, more comorbidities, increased substance use, and lower socioeconomic status would correlate with worse 2-year PROMIS PI scores.

METHODS

This study was a retrospective review of prospectively acquired data on 253 patients. Surveys were administered within 1 week of surgery and 2 years postoperatively. Bivariate and multivariable analyses were conducted to identify significant predictors of worse 2-year PROMIS PI scores and change in PROMIS PI scores.

RESULTS

Older age, higher body mass index, more comorbidities, lower preoperative expectations, more prior surgeries, unemployment, smoking, higher American Society of Anesthesiologists (ASA) score, and multiple other socio-demographic factors were correlated with worse 2-year PROMIS PI scores (P ≤ .018). Similar factors were also correlated with less improvement in 2-year PROMIS PI scores (P ≤ .048). Worse scores on all preoperative patient-reported outcome measures correlated with worse 2-year PROMIS PI scores (P ≤ .007). Multivariable analysis identified smoking history, less frequent alcohol consumption, worse preoperative PROMIS social satisfaction and Numeric Pain Scale whole body scores, and higher ASA scores as independent predictors of worse 2-year PROMIS PI. The same factors in addition to better baseline PROMIS PI were predictive of less improvement in 2-year PROMIS PI.

CONCLUSION

Numerous preoperative factors were predictive of worse postoperative 2-year PROMIS PI and less improvement in 2-year PROMIS PI for patients undergoing hand and wrist surgery.

Reliability, Validity and Responsiveness of the Slovenian Version of the Patient Evaluation Measure (PEM-Slo) in Patients with Wrist and Hand Disorders

Introduction

The Patient Evaluation Measure (PEM) is a region-specific patient reported outcome measure (PROM) for hand and wrist disorders, first introduced in English for patients with hand surgery in 1995. The purpose of the study was to assess the psychometric properties of the translated and cross-culturally adapted Slovenian version of PEM (PEM-Slo).

Methods

The study was designed as a single-centre observational prospective study conducted from July 2020 to March 2021. The psychometric evaluation was performed on fifty-one patients with miscellaneous hand and wrist disorders. Reliability was tested for internal consistency and test-retest reliability. Convergent and divergent validity, responsiveness, floor and ceiling effect, and interpretability with the determination of minimal detectable change (MDC) and minimal clinically important difference (MCID) were assessed.

Results

The PEM-Slo has excellent internal consistency (Cronbach's α 0.932) and good to excellent test-retest reliability (intraclass correlation coefficient=0.874). Convergent validity was proved with high to moderate correlations of PEM-Slo with DASH, grip strength and self-care, usual activities, and pain EQ-5D-5L subscales, whereas no correlation of PEM-Slo with EQ-5D-5L mobility and anxiety/depression subscale confirmed divergent validity. The PEM-Slo responsiveness was high (standardised response mean=1.42, effect size=1.25). MDC was 18.01 and MCID was 17.31. No floor or ceiling effect was found.

Conclusion

The PEM-Slo is a reliable, valid and responsive PROM for Slovenian-speaking patients with hand and wrist disorders.

Novel Tools to Approach and Measure Outcomes in Patients with Fractures

Upper extremity fractures are prevalent and pose a great burden to patients and society. In the US alone, the annual incidence of upper extremity fractures is 67.6 fractures per 10,000 persons. While the majority of patients with upper extremity fractures demonstrate satisfactory outcomes when treated appropriately (the details of which are discussed in prior articles), the importance of follow-up and outcome measurement cannot be understated. Outcome measurement allows for accountability and improvement in clinical outcomes and research. The purpose of this article is to describe recent advances in methods and tools for assessing clinical and research outcomes in hand and upper extremity care. Three specific advances that are broadly changing the landscape of follow-up care of our patients include: 1) telemedicine, 2) patient-reported outcome measurement, and 3) wearables/remote patient monitoring.

Zurich Appearance Score for Hands: Development and Validation of an Instrument for Assessing Hand Appearance in Congenital Upper Limb Differences

PURPOSE

The appearance of the hand is relevant to individual activity and participation. Improving appearance is often one of the essential goals of hand surgery. The aim of this study was to describe and validate an instrument for quantitatively assessing hand appearance in congenital upper limb differences (CULD).

METHODS

The Zurich Appearance Score for Hands (ZASH) was developed as a summed score of 6 items: 1 for overall appearance and 5 specific items for the skin, proportions of the hand, the number of digits, the shape of fingers and the thumb, and the position of the thumb. Each item can be rated on an 11-point Likert scale. Here, 448 participants (age, 14-83 years) were asked to rate the images of 17 hands, including standardized 3-dimensional photorealistic computer graphics and photographs of children's hands with or without CULDs, some after surgical correction. The sociodemographic characteristics of the participants were measured using a short questionnaire.

RESULTS

The ZASH score for all CULDs was significantly lower than the ZASH score for normal hands. Correlations for overall appearance and the ZASH score were high (r = 0.77-0.87). The internal consistency of all ZASH scores was good to excellent (Cronbach α = 0.82-0.94). The test-retest reliability in a subgroup of 54 participants was good (r = 0.53-0.79). The interrater reliability of the ZASH score was moderate (intraclass correlation = 0.47).

CONCLUSIONS

The ZASH is a valid and moderately reliable instrument for assessing hand appearance in children with CULDs.

CLINICAL RELEVANCE

Achieving the best possible appearance is the one of the most relevant goals of hand surgery. Assessment with validated instruments provides evidence on how to approach this goal. Further studies may clarify whether the ZASH can be recommended for all hand conditions and to what extent observers' sociocultural and professional backgrounds affect perception.

Patient-Derived Framework for Quality in Hand Surgery: A Qualitative Analysis

PURPOSE

Despite the growing attention to evaluating care from the patient perspective, the most common definitions and measurements of quality are currently defined by physicians and health systems. Studies have demonstrated how a lack of patient input can lead to discrepancies between patients' and physicians' assessments of quality and, subsequently, worse patient outcomes. Although quality measures are increasingly used in hand surgery, insufficient work has examined whether these quality measures align with what matters to patients. We completed a qualitative study to assess how patients define high-quality care through the pre-, peri-, and postoperative phases of care in hand surgery.

METHODS

Based on our prior work, we created an open-ended interview guide and conducted semistructured interviews with 43 hand surgery patients at 5 tertiary-care institutions during various phases of care. We completed a thematic analysis to generate subcodes and open codes, to identify themes in high-quality care from the patient perspective.

RESULTS

Patients defined high-quality care as a process of (1) setting and meeting clear expectations; (2) achieving functional goals after surgery; and (3) feeling comfortable with and cared for by the care team. We identified the following 4 patient-centered themes that contributed to high-quality care: (1) communication between the patient and care team through all phases of care; (2) efficient and accurate diagnosis and treatment; (3) satisfactory treatment outcomes and postsurgical experience; and (4) acceptable systemic aspects of care.

CONCLUSIONS

Efforts to improve health care delivery should include areas of care that are important to patients. Our results suggest that measuring aspects of care that often go without assessments, such as communication, can maximize care quality as defined by patients.

CLINICAL RELEVANCE

The themes identified in this study can inform efforts towards patient-centered quality measure development.

Establishing the Minimal Clinically Important Difference and Substantial Clinical Benefit for the Pain Visual Analog Scale in a Postoperative Hand Surgery Population

PURPOSE

Although the pain visual analog scale (VAS-pain) is a ubiquitous patient-reported outcome instrument, it remains unclear how to interpret changes or differences in scores. Therefore, our purpose was to calculate the minimal clinically important difference (MCID) and substantial clinical benefit (SCB) for the VAS-pain instrument in a nonshoulder hand and upper extremity postoperative population.

METHODS

Adult postoperative patients treated by 1 of 5 fellowship-trained orthopedic hand surgeons at a single tertiary academic medical center were identified. Inclusion required VAS-pain scores at baseline (up to 3 months before surgery) and follow-up (up to 4 months after surgery), in addition to a response to a pain-specific anchor question at follow-up. The MCID estimates were calculated with (1) the 1/2 standard deviation method; and (2) an anchor-based approach. The SCB estimates were calculated with (1) an anchor-based approach; and (2) a receiver operator curve method that maximized the sensitivity and specificity for detecting a "much improved" pain status.

RESULTS

There were 667 and 148 total patients included in the MCID and SCB analyses, respectively. The 1/2 standard deviation MCID estimate was 1.6, and the anchor-based estimate was 1.9. The anchor-based SCB estimate was 2.2. The receiver operator curve analysis yielded an SCB estimate of 2.6, with an area under the curve of 0.72, consistent with acceptable discrimination.

CONCLUSIONS

We propose MCID values in the range of 1.6 to 1.9 and SCB values in the range of 2.2 to 2.6 for the VAS-pain instrument in a nonshoulder hand and upper extremity postoperative population.

CLINICAL RELEVANCE

These MCID and SCB estimates may be useful for powering clinical studies and when interpreting VAS-pain score changes or differences reported in the hand surgery literature. These values are to be applied at a population level, and should not be applied to assess the improvement, or lack thereof, for individual patients.

Evaluation of the PROMIS Upper Extremity Against Validated Patient-Reported Outcomes in Patients With Early Carpometacarpal Osteoarthritis

PURPOSE

Internal consistency, construct, and criterion validity of the Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) v1.2 were evaluated in patients with early-stage carpometacarpal (CMC) osteoarthritis (OA). We hypothesized that in patients with early CMC OA, PROMIS UE scores would: (1) be lower than those in asymptomatic controls; (2) correlate with established patient-reported outcomes; (3) correlate with pinch and grip strengths; and (4) not correlate with radiographic disease progression.

METHODS

Patients with early CMC OA (modified Eaton stage 0 or 1) and matched asymptomatic control patients completed the PROMIS UE, Australian and Canadian Osteoarthritis Hand Index, and Patient-Rated Wrist-Hand Evaluation at 2 time points. The PROMIS UE's internal consistency was evaluated by Cronbach's alpha, construct validity by Spearman correlation coefficients among the patient-reported outcome measures, and criterion validity using measures of strength. A floor or ceiling effect was indicated if more than 15% of patients achieved the lowest or highest possible score.

RESULTS

The PROMIS UE had high internal consistency. Patients with early CMC OA had a lower score than healthy controls (average, 42 vs 54, respectively). We observed moderate to high correlations between the PROMIS UEv1.2, Australian and Canadian Osteoarthritis Hand Index, and Patient-Rated Wrist-Hand Evaluation and good criterion validity when compared to key pinch and grip strengths. The PROMIS UE did not correlate to radiographic disease severity.

CONCLUSIONS

The PROMIS UE had a high correlation with Australian and Canadian Osteoarthritis Hand Index and a moderate correlation with Patient-Rated Wrist-Hand Evaluation. The PROMIS UE had high internal consistency and good criterion validity.

CLINICAL RELEVANCE

The PROMIS UE is a valid assessment for disability in patients with early CMC OA and can serve as a clinical adjunct to an outcome assessment.

Establishing the Substantial Clinical Benefit in a Non-Shoulder Hand and Upper Extremity Population for the QuickDASH and PROMIS Upper Extremity and Physical Function Computer Adaptive Tests

PURPOSE

It is unclear what score changes on the abbreviated Disabilities of the Arm, Hand, and Shoulder (QuickDASH), Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) computer adaptive test (CAT), and PROMIS physical function (PF) CAT represent a substantial improvement. We calculated the substantial clinical benefit (SCB) for these 3 instruments in a non-shoulder hand and upper extremity population.

METHODS

Adult patients treated between March 2015 and September 2019 at a single academic tertiary institution were identified. The QuickDASH, PROMIS UE CAT v2.0, and PROMIS PF CAT v2.0 scores were collected using a tablet computer. Responses to the QuickDASH both at baseline and follow-up 6 ± 4 weeks later, 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?" were required for inclusion. A second anchor question querying treatment-related improvement was also used. The SCB was calculated using an anchor-based approach comparing the mean change difference between groups reporting no change and a maximal change for both anchor questions.

RESULTS

Of 1,119 included participants, the mean age was 48 ± 17 years, 53% were women, and half were recovering from surgery. Score changes between baseline and follow-up were significantly different between groups reporting no improvement and maximal improvement on both anchor questions. The SCB values ranged between 16.9 and 22.8 on the QuickDASH, 5.9 and 7.1 on the UE CAT, and 3.5 and 6.7 on the PF CAT.

CONCLUSIONS

These score improvements for the QuickDASH, UE CAT, and PF CAT represent a substantial clinical improvement in a non-shoulder hand and upper extremity population.

CLINICAL RELEVANCE

These SCB estimates may assist with the interpretation of outcome scores at a population level.

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.

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.

Predictors of Hand Function Following Digit Replantation: Quantitative Review and Meta-Analysis

Background: Digit replantation affords the opportunity to restore hand function following amputation. To date, however, few studies have evaluated functional outcomes following replantation. Therefore, it was the objective of this study to perform a meta-analysis to better characterize the predictors of hand function. Methods: A literature search was performed using the PubMed database to identify studies that focused on digit amputation/replantation and functional outcomes. Studies were evaluated for patient- and injury-related factors and their respective effects on clinical outcomes of sensation, grip strength, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. Statistical analysis was conducted across the pooled data set to identify significant trends. Results: Twenty-eight studies representing 618 replanted digits were included in this study. We found the average grip strength was 78.7% (relative to contralateral), the average 2-point discrimination (2PD) was 7.8 mm, and the average DASH score was 12.81. After conducting statistical analysis, we found patients with more proximal injuries had lower grip strength scores (P < .05). We found 2PD scores were influenced by age, mechanism of injury, and amputation level (P < .05). Finally, we found DASH scores after replantation were predicted by mechanism of injury and level of amputation (P < .05). The following variables did not influence outcomes: gender, tobacco use, ischemia time, and digit number. Conclusions: Digit replant does not restore premorbid hand function but does result in adequate hand function. Expected functional outcomes following replant should be considered in the decision-making process. These data can help risk-stratify patients, guide postreplant expectations, and influence the decision for replantation.

Access to Hand Therapy Following Surgery in the United States: Barriers and Facilitators

Hand therapy is a time-sensitive and essential postoperative service for patients undergoing reparative or corrective procedures in the hand and plays an important role in achieving best functional outcomes. In the United States, therapy is an independent service from a payer's standpoint. Access is affected by global and distinct factors in health care. This article presents views on certain aspects of health care that aide in and those that impede access to hand therapy for patients in the United States, and concludes with a brief glimpse into some ongoing efforts to improve access for patients.

Polish version of the Patient-Rated Ulnar Nerve Evaluation in preoperative patients: Translation and psychometric testing

STUDY DESIGN

Cross-sectional design.

INTRODUCTION

This study examined the translated English to Polish version of the Patient-Rated Ulnar Nerve Evaluation (PRUNE) for its internal consistency, test-retest reliability, and construct validity.

METHODS

During the first assessment validity testing, a total of 39 consecutive patients with cubital tunnel syndrome completed the PRUNE, Michigan Hand Outcome Questionnaire, Disabilities of the Arm, Shoulder, and Hand questionnaire, and Patient Evaluation Measure in conjunction with the grip and key pinch tests and pain score (by Visual Analogue Scale). Cronbach's alpha (CA), intraclass correlation coefficient (ICC), and the Bland-Altman plot were used to evaluate internal consistency, test-retest reliability, and agreement, respectively. Analysis of variance compared the PRUNE score with the McGowan clinical stages.

RESULTS

After a 1-day interval, 19 patients completed the PRUNE for the second time. The total PRUNE score was 44.4 ± 20.4, CA = 0.93, and ICC = 0.921. The total PRUNE score limits of agreement varied from -9.87 to 7.55 points. PRUNE subscale CA ranged from 0.79 to 092; the ICC varied from 0.738 to 0.911. The construct validity revealed a strong association with Michigan Hand Outcome Questionnaire (R = -0.83; P < .000), and moderate with Disabilities of the Arm, Shoulder, and Hand (R = 0.75; P < .000), Patient Evaluation Measure (R = 0.75; P < .000), and Visual Analogue Scale (R = 0.69; P < .000). The grip and pinch tests had low and no correlation with the total PRUNE score, respectively.

CONCLUSION

The Polish version of PRUNE showed good psychometric properties for use in both clinical and research practice in patients with cubital tunnel syndrome of varying intensity.

Outcomes Following Replantation/Revascularization in the Hand

The variability in reported outcomes and outcome measures used in digit replantation makes it difficult to compare results among studies. This article reviews the principles of measuring functional and patient-reported outcomes after replantation, and describes the recommended instruments to use and ways to report results.

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.

Long-term functional, subjective and psychological results after single digit replantation

Objective

The aim of this study was to analyse the long-term functional, subjective, and psychological results after single-digit replantation.

Methods

Thirty cases of digital replantation (14 thumbs, 12 index fingers, 2 middle fingers, 1 ring finger, and 1 little finger) in 30 patients (7 females and 23 males) with a mean age of 44.2 years (20–65 years) were evaluated at the end of a mean follow-up time of 36 months (19–50 months). The active range of motion of joints, grip and pinch strength, cutaneous sensibility, upper-extremity functioning, and subjective satisfaction were determined using the Disability of Arm, Shoulder, and Hand (DASH) questionnaire and the Michigan Hand Outcomes questionnaire (MHQ). Psychological sequelae, including depression, anxiety, and posttraumatic stress disorder (PTSD), were assessed. A correlation analysis among variables was also performed.

Results

The mean score for the DASH questionnaire was 6.6 (range: 0–39.2). The symptom of cold intolerance occurred in 53% of the patients. Two patients were diagnosed with depression, and only one patient exhibited PTSD. The DASH score had a good statistical correlation with total grip strength, pinch grip strength, and static two-point discrimination (S-2PD) (P < 0.05). Several aspects of the MHQ were also statistically relevant to some or all of the three objective results. Furthermore, the grip strength showed significant correlation with DASH and most aspects of the MHQ in multivariate logistic regression analysis (P < 0.05).

Conclusion

Total grip strength is the most important factor positively related to subjective outcomes. The incidence rates of psychological symptoms after digit replantation are very low at long-term follow-up.

Ring Avulsion Injuries: A Systematic Review

BACKGROUND

Ring avulsion injuries can range from soft tissue injury to complete amputation. Grading systems have been developed to guide treatment, but there is controversy with high-grade injuries. Traditionally, advanced ring injuries have been treated with completion amputation, but there is evidence that severe ring injuries can be salvaged. The purpose of this systematic review was to pool the current published data on ring injuries.

METHODS

A systematic review of the English literature published from 1980 to 2015 in PubMed and MEDLINE databases was conducted to identify patients who underwent treatment for ring avulsion injuries.

RESULTS

Twenty studies of ring avulsion injuries met the inclusion criteria. There were a total of 572 patients reported with ring avulsion injuries. The Urbaniak class breakdown was class I (54 patients), class II (204 patients), and class III (314 patients). The average total arc of motion (TAM) for patients with a class I injury was 201.25 (n = 40). The average 2-point discrimination was 5.6 (n = 10). The average TAM for patients with a class II injury undergoing microsurgical revascularization was 187.0 (n = 114), and the average 2-point discrimination was 8.3 (n = 40). The average TAM for patients with a class III injury undergoing microsurgical revascularization was 168.2 (n = 170), and the average 2-point discrimination was 10.5 (n = 97).

CONCLUSIONS

Ring avulsion injuries are commonly classified with the Urbaniak class system. Outcomes are superior for class I and II injuries, and there are select class III injuries that can be treated with replantation. Shared decision making with patients is imperative to determine whether replantation is appropriate.

Remote Collection of Patient-Reported Outcomes Following Outpatient Hand Surgery: A Randomized Trial of Telephone, Mail, and E-Mail

PURPOSE

Obtaining remote patient-reported outcomes (PRO) is limited by low patient response rates and resource-intensive collection methods. We hypothesized that an e-mail-delivered Web-based data collection tool would outperform the traditional methods of telephone and standard mail for collecting long-term Boston Carpal Tunnel Questionnaire (BCTQ) scores at a minimum of 1 year following carpal tunnel release (CTR).

METHODS

We conducted a randomized trial of 969 patients who underwent CTR at a tertiary medical center within the past 5 years. Participants were randomized to the PRO collection methods of mail, telephone, and e-mail. The primary outcome was survey response rate at 1 year after surgery. Secondary analyses included data completeness and the effect of time from surgery, mode effects, and patient modality preference.

RESULTS

At 1 year from surgery, the response rates were 64% for telephone and 42% for both mail and e-mail. Ninety-nine percent of telephone surveys were complete compared with 88% and 83% for mail and e-mail, respectively. There was no significant difference in the overall response rate at 1 or 5 years after surgery, nor in the BCTQ score between the modalities.

CONCLUSIONS

A higher response rate and increased survey completeness was achieved by telephone contact methods compared with standard mailings or Web-based methods for PRO collection after CTR 1 to 5 years after surgery. A Web-based method demonstrated response rates equivalent to those of standard mail, was the most preferred modality, and offered logistical advantages such as automation and immediate integration with outcome databases.

CLINICAL RELEVANCE

Obtaining PRO routinely after treatment may increase in importance. A Web-based interface may assist clinicians in decreasing the resource utilization typically associated with more traditional methods used to obtain outcome data.

Outcomes Assessment After Hand Burns

Accurately assessing function and disability after hand burns is imperative to improving the management of patients. The biological, social, and psychological impact of these injuries should be considered. The International Classification of Functioning Disability (ICF) and Health Core Sets for Hand Conditions provides a guide to what should be measured and reported. Although many outcomes measures instruments are available to assess patients with hand or burn injuries, few are validated in the subpopulation of hand burns. Further efforts are required to investigate the ability of current assessment instruments to evaluate hand burn outcomes within the ICF framework.

Measuring Functional and Patient-Reported Outcomes After Treatment of Mutilating Hand Injuries: A Global Health Approach

Understanding the global burden of trauma, particularly upper extremity trauma, is necessary in addressing the need for surgical services. Critical to that mission is to understand, and accurately measure, disability and related disability-adjusted life-years from massive upper extremity trauma. The impact of these injuries is magnified when considering that they frequently occur to young people in prime working years. This article discusses these social and medical system issues and reviews components of a comprehensive approach to measuring outcomes after these injuries. Patient-reported outcomes are highlighted. Methods of optimizing outcomes measurements and studies, disability assessments, and associated research are also discussed.

Setting the Goals in the Management of Mutilated Injuries of the Hand-Impressions Based on the Ganga Hospital Experience

Mutilated injuries need to be treated aggressively and appropriately to avoid amputation or severe disability in the individual. Assessment of the management of these injuries on a global level reveals that there is a gap between the need and availability of the skilled manpower to manage these injuries. There is also a gap in the utilization of the available services. These gaps need to be covered or narrowed as far as possible. Although some measures need policy changes and improvement of health care delivery infrastructure, simpler measures taken at the final health care delivery level can significantly improve the final outcome.

A Unified Approach to Outcomes Assessment for Distal Radius Fractures

Distal radius fractures are one of the most common upper extremity injuries. Currently, outcome assessment after treatment of these injuries varies widely with respect to the measures that are used, timing of assessment, and the end points that are considered. A more consistent approach to outcomes assessment would provide a standard by which to assess treatment options and best practices. In this summary, we review the consensus regarding outcomes assessment after distal radius fractures and propose a systematic approach that integrates performance, patient-reported outcomes, pain, complications, and radiographs.

Applying the Patient-Reported Outcomes Measurement Information System to Assess Upper Extremity Function among Children with Congenital Hand Differences

BACKGROUND

Few studies have evaluated self-assessment tools among children with congenital hand differences. The authors compared three upper extremity disability instruments with the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Upper Extremity Item Bank.

METHODS

Thirty-three children (aged 6 to 17 years) with congenital hand differences completed the Pediatric Outcomes Data Collection Instrument; the Michigan Hand Outcomes Questionnaire; the Disabilities of the Arm, Shoulder, and Hand questionnaire; and the PROMIS Upper Extremity short form and computerized adaptive test. Hand function was also assessed, and construct validity and feasibility were examined.

RESULTS

PROMIS demonstrated good construct validity. Short form and computerized adaptive test were highly correlated with Disabilities of the Arm, Shoulder, and Hand questionnaire scores (r = 0.80, p < 0.001) and Pediatric Outcomes Data Collection Instrument domains (r = 0.70, p < 0.001). PROMIS was moderately correlated with the Michigan Hand Outcomes Questionnaire (r = 0.40, p < 0.05). PROMIS scores also correlated with grip (r = 0.60, p < 0.001) and pinch strength (r = 0.50, p < 0.001). Compared with the Pediatric Outcomes Data Collection Instrument and the Disabilities of the Arm, Shoulder, and Hand and Michigan Hand Outcomes questionnaires, PROMIS required the least time to complete with fewer children requiring assistance.

CONCLUSION

The Patient-Reported Outcomes Measurement Information System is highly correlated with both functional assessment and self-reported function among children with congenital hand differences.

A Systematic Review of Outcomes after Revision Amputation for Treatment of Traumatic Finger Amputation

BACKGROUND

Revision amputation is often the treatment for traumatic finger amputation injuries. However, patient outcomes are inadequately reported, and their impact is poorly understood. The authors performed a systematic review to evaluate outcomes of revision amputation and amputation wound coverage techniques.

METHODS

The authors searched all available English literature in the PubMed and Embase databases for articles reporting outcomes of nonreplantation treatments for traumatic finger amputation injuries, including revision amputation, local digital flaps, skin grafting, and conservative treatment. Data extracted were study characteristics, patient demographic data, sensory and functional outcomes, patient-reported outcomes, and complications.

RESULTS

A total of 1659 articles were screened, yielding 43 studies for review. Mean static two-point discrimination was 5.0 ± 1.5 mm (n = 23 studies) overall, 6.1 ± 2.4 mm after local flap procedures, and 3.8 ± 0.4 mm after revision amputation. Mean total active motion was 93 ± 8 percent of normal (n = 6 studies) overall. It was 90 ± 9 percent of normal after local flap procedures and 95 percent of normal after revision amputation. Seventy-seven percent of patients reported cold intolerance after revision amputation. Ninety-one percent of patients (217 of 238) reported "satisfactory" or "good/excellent" ratings regardless of treatment.

CONCLUSIONS

Revision amputation and conservative treatments result in better static two-point discrimination outcomes compared with local flaps. All techniques preserve total active motion, although arc of motion is slightly better with revision amputation. Revision amputation procedures are frequently associated with cold intolerance. Patients report "satisfactory," "good," or "excellent" ratings in appearance and quality of life with all nonreplantation techniques.

A randomized trial of the disabilities of the arm, shoulder, and hand administration: tablet computer versus paper and pencil

PURPOSE

To compare the Disabilities of the Arm, Shoulder, and Hand (DASH) patient-reported outcome measure as administered by tablet computer to the traditional paper format.

METHODS

In a prospective, randomized study design, 223 consecutive adult patients who presented to the clinic of a single hand surgeon at a tertiary medical center were randomized by visit time to receive the DASH by either paper or tablet computer. Test completeness, time to completion, DASH score, and diagnostic and demographic data were collected and compared between the two cohorts. In total, 120 participants took the DASH using the tablet and 103 using paper.

RESULTS

43% of the paper surveys had at least one question that was omitted, compared with 13% in the tablet group; 14% of the paper surveys were not scoreable (< 27 questions answered) compared with 4% of the tablet surveys. The mean time to complete was 3.1 minutes for the paper version of the DASH and 4.3 minutes for the tablet version. Among our study population, there was no influence of age, sex, or diagnosis category on the time required to complete either version of the test. The mean DASH score was 45 for the paper version and 32 for the tablet version.

CONCLUSIONS

The use of digital data entry methods in the arena of health care outcomes research is increasing. Administration of the DASH via a tablet computer resulted in more complete data, slightly increased responder burden, and a lower DASH score. This finding may have important implications for the use of this metric in an electronic format in future research endeavors.

Evaluation of the PROMIS physical function computer adaptive test in the upper extremity

PURPOSE

To compare psychometric and responder burden characteristics between the Patient-Reported Outcomes Measurement Information System Physical Function Computer Adaptive Test (PF CAT) and the Disabilities of Arm, Shoulder, and Hand (DASH) instruments in a tertiary hand and upper extremity practice.

METHODS

Adult patients who presented to the clinic of 2 hand and upper extremity surgeons in a university-based tertiary care center were enrolled in this study. Participants received the DASH and PF CAT administered via tablet computer. Time to completion was recorded for both the DASH and PF CAT. We conducted statistical analyses to calculate Pearson correlation coefficients between the 2 instruments and performed a Rasch item response theory analysis to determine dimensionality, reliability, ceiling and floor effects, and item bias for each instrument.

RESULTS

A total of 134 patients were included. Time to completion for the DASH was 262 seconds, and for the PF CAT 57 seconds. The instruments had strong correlation (r = 0.726). The item and Pearson reliability were 0.97 and 0.94, respectively, for the DASH and 0.99 and 0.96 for the PF CAT. The DASH and PF CAT had 5% and 5% of unexplained variance, respectively. The DASH exhibited 5% of ceiling effect and 1% floor effect whereas the PF CAT had no ceiling or floor effects.

CONCLUSIONS

The psychometric characteristics of the Patient-Reported Outcomes Measurement Information System PF CAT instrument compared favorably with the DASH in a tertiary upper extremity practice. Patient time burden was significantly reduced with the PF CAT compared with the DASH.

Measuring and understanding treatment effectiveness in hand surgery

Incorporating evidence-based medicine into practice is now an expectation for hand surgeons. Hand surgeons need to be able to assess associated benefits, risks, cost, and applicability of a treatment option when providing care to their patients. Using a clinical example, this article takes the reader through the three-step approach when using a publication from the medical literature on therapy. The focus of this article is primarily the second and third steps, which involve measuring and understanding treatment effectiveness.

Do patient-reported outcome measures capture functioning aspects and environmental factors important to individuals with injuries or disorders of the hand?

STUDY DESIGN

Qualitative study.

INTRODUCTION

Clinical outcome evaluation needs to consider the patient perspective for an in-depth understanding of functioning and disability.

PURPOSE OF THE STUDY

To explore whether patient-reported outcome measures (PROMs) used in the field of hand injuries or hand disorders, capture functioning aspects and environmental factors important to the patients.

METHODS

We performed a qualitative study and a systematic literature review. The focus group sessions were recorded, transcribed verbatim, and the identified concepts were linked to the ICF. We searched in MEDLINE for reviews, related to injuries or disorders of the hand, reporting on PROMs. We linked the items of the identified PROMs to the ICF and compared the qualitative data with the content of the PROMs.

RESULTS

Statements from 45 individuals who participated in eight focus groups were linked to 97 categories of the ICF. From 15 reviews included, eight PROMs were selected. The selected PROMs capture 34 of the categories retrieved from the qualitative data.

CONCLUSIONS

PROMs used in the context of hand injuries or hand disorders capture only in parts the functioning aspects important to the patients.

Psychometric properties of health-related quality of life instruments in patients undergoing palmar fasciectomy for dupuytren's disease: a prospective study

BACKGROUND

The traditional outcome measured following treatment of Dupuytren's Disease (DD) has been digital range of motion; specifically the gain in digital extension. The outcomes research movement in the last three decades however has been advocating the measurement of outcomes from the patient's perspective using Health-Related Quality of Life questionnaires (HRQOL). Although several generic and region-specific HRQOL questionnaires exist, there is no guidance as to which one is the most appropriate for this population. The objective of this study is to evaluate the psychometric properties of three self-reported HRQOL outcome measures in patients with DD.

METHODS

Patients with DD were enrolled from the practices of three plastic surgeons. Test-retest reliability, concurrent validity and responsiveness of three HRQOL questionnaires were compared in a prospective study design. The HRQOL measures included Health Utilities Index Mark 3 (HUI3), Short Form-36 (SF-36), and the Michigan Hand Questionnaire (MHQ).

RESULTS

All three measures demonstrated good test-retest reliability (ICC = 0.77-0.85). Concurrent validity was found between the HUI3 pain and dexterity attributes and SF-36 physical summary score. The sensitivity of the MHQ to detect changes in the status of the patient was found to be high (effect size = 1.14) whereas that of the SF-36 was trivial.

CONCLUSIONS

The HUI3 and the MHQ seem to be reliable and valid tools to assess the HRQOL in patients with Dupuytren's Disease.

Challenges in measuring outcomes following digital replantation

In the early period of replantation surgery, the emphasis was on digit survival. Subsequently, with better microsurgical techniques and instrumentation, the focus has shifted to function and in recent years to consideration of cost-effectiveness. Despite over 40 years of effort in refining digital replantation surgery, a rigorous evaluation of the outcomes of digital replantation has not been performed. This is because of the many confounding variables that influence outcome comparisons. These variables include the mechanism of injury (guillotine, crush, avulsion), the injury itself (total, near total, subtotal, partial amputation), and the surgical procedure (replantation, revascularization). In addition, the traditional outcome measures (two-point discrimination, range of motion, grip strength, or the ability to return to work) are reported inconsistently and vary widely among publications. All these factors make meaningful comparison of outcomes difficult. The recent emphasis on outcome research and cost-effectiveness necessitates a rethinking in the way we report outcomes of digital replantation. In this article, the authors summarize the challenges in assessing outcomes of digital replantation and explain the need to measure outcomes using rigorous clinical research designs that incorporate cost-effectiveness studies in the research protocol.

Contribution of functional parameters to patient-rated outcomes after surgical treatment of distal radius fractures

PURPOSE

Outcomes of distal radius fractures can be measured radiographically, functionally, or via patient-rated questionnaires, but previous studies report conflicting results regarding the relationship between these outcomes. Our specific aim was to explore the role that functional outcomes have in the score of the Michigan Hand Outcomes Questionnaire (MHQ), a patient-rated hand instrument.

METHODS

We obtained data for 207 patients. Demographic information was collected as part of the MHQ. Function (wrist motion and grip and pinch strength) was assessed 3 and 6 months after fracture fixation. We applied linear regression analysis to determine each item's contribution to the total MHQ score.

RESULTS

After we applied linear regression analysis, we determined that 3 months after fixation, all included factors contributed 37% of the MHQ score. Only the grip strength difference between the injured and uninjured hands was significantly associated, contributing 22% of the MHQ score. Six weeks and 6 months after fixation, all included factors contributed 43% and 34%, respectively, of the MHQ score. No individual factors were significant contributors.

CONCLUSIONS

Measured functional outcomes variables account for less than 40% of the total MHQ score. Identifying the unmeasured factors that make up the additional 60% of the total MHQ score would be beneficial in the continued examination of patient-rated outcomes. Furthermore, the use of multiple outcomes assessment modalities should be considered in any study measuring patient-rated outcomes.

An outcome study for ulnar neuropathy at the elbow: a multicenter study by the surgery for ulnar nerve (SUN) study group

BACKGROUND

Many instruments have been developed to measure upper extremity disability, but few have been applied to ulnar neuropathy at the elbow (UNE).

OBJECTIVE

We measured patient outcomes following ulnar nerve decompression to (1) identify the most appropriate outcomes tools for UNE and (2) to describe outcomes following ulnar nerve decompression.

METHODS

Thirty-nine patients from 5 centers were followed prospectively after nerve decompression. Outcomes were measured preoperatively and at 6 weeks, 3 months, 6 months, and 12 months postoperatively. Each patient completed the Michigan Hand Questionnaire (MHQ), Carpal Tunnel Questionnaire (CTQ), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaires. Grip, key-pinch strength, Semmes-Weinstein monofilament, and 2-point discrimination were measured. Construct validity was calculated by using Spearman correlation coefficients between questionnaire scores and physical and sensory measures. Responsiveness was assessed by standardized response means.

RESULTS

Key-pinch (P = .008) and Semmes-Weinstein monofilament testing of the ulnar ring (P < .001) and small finger (radial: P = .004; ulnar: P < .001) improved following decompression. Two-point discrimination improved significantly across the radial (P = .009) and ulnar (P = .007) small finger. Improved symptoms and function were noted by the CTQ (preoperative CTQ symptom score 2.73 vs 1.90 postoperatively, P < .001), DASH (P < .001), and MHQ: function (P < .001), activities of daily living (P = .003), work (P = .006), pain (P < .001), and satisfaction (P < .001). All surveys demonstrated strong construct validity, defined by correlation with functional outcomes, but MHQ and CTQ symptom instruments demonstrated the highest responsiveness.

CONCLUSION

Patient-reported outcomes improve following ulnar nerve decompression, including pain, function, and satisfaction. The MHQ and CTQ are more responsive than the DASH for isolated UNE treated with decompression.

Evaluation of Non Diseased Specified Outcome Measures in Hand Injuries to Assess Activity and Participation Based on ICF Content

The objective of the study is to provide information about non disease specified outcome measures which evaluate disability in patients who have impairments in hand and upper extremity and to find the extent to which they are evaluating "disability" based on ICF hand Core Set (activity limitation and participation restriction). MEDLINE, CINAHL, GOOGLE SCHOLAR , OVID and SCIENCE DIRECT databases were systematically searched for studies on non disease specified outcome measures used to evaluate upper extremity function; only studies written in English were considered. We reviewed titles and abstracts of the identified studies to determine whether the studies met predefined eligibility criteria (eg, non disease specified out come measures used in hand injured patients). All the outcome measures which had eligibility included. After full text review ,7 non disease specified outcome measures in hand were identified. Studies were extracted, and the information retrieved from them. All the outcome measures which had incuded, were linked with ICF hand core set disability part (activity and participation). All of them only linked to 16 (42 %) components of ICF hand Core Set, which were most activity and less participation from ICF. None of the non disease specified out come measures in hand injuries cover all domains of disability from the ICF Hand Core Set.

Cross-cultural adaptation, reliability and validity of the Spanish version of the Upper Limb Functional Index

BACKGROUND

The Upper Limb Functional Index (ULFI) is an internationally widely used outcome measure with robust, valid psychometric properties. The purpose of study is to develop and validate a ULFI Spanish-version (ULFI-Sp).

METHODS

A two stage observational study was conducted. The ULFI was cross-culturally adapted to Spanish through double forward and backward translations, the psychometric properties were then validated. Participants (n = 126) with various upper limb conditions of >12 weeks duration completed the ULFI-Sp, QuickDASH and the Euroqol Health Questionnaire 5 Dimensions (EQ-5D-3 L). The full sample determined internal consistency, concurrent criterion validity, construct validity and factor structure; a subgroup (n = 35) determined reliability at seven days.

RESULTS

The ULFI-Sp demonstrated high internal consistency (α = 0.94) and reliability (r = 0.93). Factor structure was one-dimensional and supported construct validity. Criterion validity with the EQ-5D-3 L was fair and inversely correlated (r = -0.59). The QuickDASH data was unavailable for analysis due to excessive missing responses.

CONCLUSIONS

The ULFI-Sp is a valid upper limb outcome measure with similar psychometric properties to the English language version.

Review of thumb carpometacarpal arthritis classification, treatment and outcomes

Thumb carpometacarpal osteoarthritis (CMC OA) is a common disease, affecting up to 11% and 33% of men and women in their 50s and 60s, respectively, which leads to pain, laxity and weakness of the CMC joint. Based on the staging of the CMC OA, different forms of treatment can be used, including both conservative and surgical measures. Surgical options include osteotomy, trapezial excision, ligament reconstruction with or without tendon interposition, and various prosthetic interpositional implants with or without trapezial excision. The present article reviews the staging of CMC OA, the evaluation of hand function using patient-reported questionnaires, and outcomes of both conservative and surgical treatments. The present review also introduces a commercially available interpositional spacer surgical technique for CMC OA and the early evidence that the literature has shown for improving hand function, strength and stability of the thumb CMC joint postoperatively.

Applying economic principles to outcomes analysis

The use of a tablet computer to complete the DASH questionnaire

PURPOSE

To determine whether electronic self-administration of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire using a tablet computer increased completion rate compared with paper self-administration.

METHODS

We gave the DASH in self-administered paper form to 222 new patients in a single hand surgeon's practice. After a washout period of 5 weeks, we gave the DASH in self-administered tablet computer form to 264 new patients. A maximum of 3 questions could be omitted before the questionnaire was considered unscorable. We reviewed the submitted surveys to determine the number of scorable questionnaires and the number of omitted questions in each survey. We completed univariate analysis and regression modeling to determine the influence of survey administration type on respondent error while controlling for patient age and sex.

RESULTS

Of the 486 total surveys, 60 (12%) were not scorable. A significantly higher proportion of the paper surveys (24%) were unscorable compared with electronic surveys (2%), with significantly more questions omitted in each paper survey (2.6 ± 4.4 questions) than in each electronic survey (0.1 ± 0.8 questions). Logistic regression analysis revealed survey administration mode to be significantly associated with DASH scorability while controlling for age and sex, with electronic survey administration being 14 times more likely than paper administration to yield a scorable DASH.

CONCLUSIONS

In our retrospective series, electronic self-administration of the DASH decreased the number of omitted questions and yielded a higher number of scorable questionnaires. Prospective, randomized evaluation is needed to better delineate the effect of survey administration on respondent error.

CLINICAL RELEVANCE

Administration of the DASH with a tablet computer may be beneficial for both clinical and research endeavors to increase completion rate and to gain other benefits from electronic data capture.

Applicability of large databases in outcomes research

Outcomes research serves as a mechanism to assess the quality of care, cost effectiveness of treatment, and other aspects of health care. The use of administrative databases in outcomes research is increasing in all medical specialties, including hand surgery. However, the real value of databases can be maximized with a thorough understanding of their contents, advantages, and limitations. We performed a literature review pertaining to databases in medical, surgical, and epidemiologic research, with special emphasis on orthopedic and hand surgery. This article provides an overview of the available database resources for outcomes research, their potential value to hand surgeons, and suggestions to improve their effective use.
