Responsiveness and Minimally Important Differences for 4 Patient-Reported Outcomes Measurement Information System Short Forms: Physical Function, Pain Interference, Depression, and Anxiety in Knee Osteoarthritis

Feasibility of a patient-centered method to determine meaningful change in pain intensity on a survey of patients with a history of cancer

Introduction

Current methods of determining minimally important differences (MIDs) in patient-reported outcomes (PROs) do not incorporate individual patient values.

Objectives

This study tested the feasibility of having cancer patients define a personally meaningful change in pain intensity, a method we have termed Precision PROs.

Methods

Adults with cancer and pain (n = 231) completed an electronic questionnaire twice over 2 weeks. Participants were then given their pain intensity scores with an explanation of score meaning. Participants then defined their own MIDs for an increase and decrease in pain intensity. Participants also answered 3 questions testing their understanding of the MID concept.

Results

The majority of participants could define an individually meaningful increase (97% [n = 223]) and individually meaningful decrease (98% [n = 226]) in pain intensity. Seventy-two percent of participants (n = 166) answered all test questions correctly and 26% (n = 60) answered 2 of 3 correctly. Using the individual MID, 32% (95% CI: 25.3, 40.0) of the sample experienced a meaningful change between the 2 surveys, more than other methods (z-test: 14%, 95% CI: 9.4, 20.6; distribution-based method: 24%, 95% CI: 17.7, 31.1).

Conclusions

This study showed the feasibility of the Precision PRO individual MID, which could be used in clinical care or clinical trials. Further studies are needed to compare the individual MID to current methods.

Measurement properties of the Dutch PROMIS-29 v2.1 profile in people with and without chronic conditions

PURPOSE

To investigate the structural validity, internal consistency, measurement invariance, and construct validity of the Dutch PROMIS-29 v2.1 profile, including seven physical (e.g., pain, physical function), mental (e.g., depression, anxiety), and social (e.g., role functioning) domains of health, in a Dutch general population sample including subsamples with and without chronic diseases.

METHODS

The PROMIS-29 was completed by 63,602 participants from the Lifelines cohort study. Structural validity of the PROMIS-29, including unidimensionality of each domain and the physical and mental health summary scores, was evaluated using factor analyses (criteria: CFI ≥ 0.95, TLI ≥ 0.95, RMSEA ≤ 0.06, SRMR ≤ 0.08). Internal consistency, measurement invariance (no differential item functioning (DIF) for age, gender, administration mode, educational level, ethnicity, chronic diseases), and construct validity (hypotheses on known-groups validity and correlations between domains) were assessed per domain.

RESULTS

The factor structure of the seven domains was supported (CFI = 0.994, TLI = 0.993, RMSEA = 0.046, SRMR = 0.031) as was unidimensionality of each domain, both in the entire sample and the subsamples. Model fit of the physical and mental health summary scores reached the criteria, and scoring coefficients were obtained. Cronbach's alpha for the seven PROMIS-29 domains ranged from 0.75 to 0.96 in the complete sample. No DIF was detected. Of the predefined hypotheses, 78% could be confirmed.

CONCLUSION

Sufficient structural validity, internal consistency and measurement invariance were found, both in the entire sample and in subsamples with and without chronic diseases. Requirements for sufficient evidence for construct validity were (almost) met for most subscales. Future studies should investigate test-retest reliability, measurement error, and responsiveness of the PROMIS-29.

Considerations for Selecting Cognitive Endpoints and Psychological Patient-Reported Outcomes for Clinical Trials in Pediatric Patients With Sickle Cell Disease

Pediatric patients with sickle cell disease (SCD) experience a range of medical complications that result in significant morbidity and mortality. Recent advances in prophylactic and curative treatment approaches have highlighted the need for sensitive and clinically-meaningful trial endpoints. The detrimental effects of cognitive and psychological difficulties on social and economic mobility are well described. Although numerous reviews have assessed cognitive outcomes in other rare genetic disorders, SCD has not received the same focus. This review describes the cognitive (i.e., executive function and processing speed) and psychological domains (i.e., depression and anxiety) that are consistently associated with SCD pathology and, therefore, may be of particular interest as clinical trial endpoints. We then discuss corresponding well-validated and reliable cognitive tests and patient-reported outcomes (PROs) that may be appropriate for clinical trials given their robust psychometric properties, ease of administration, and previous use in the SCD population. Further, we provide a discussion of potential pitfalls and considerations to guide endpoint selection. In line with the move toward patient-centered medicine, we identify specific tests (e.g., NIH Toolbox Cognition Module, Wechsler Cancellation Test) and psychological PROs (e.g., PROMIS depression and anxiety scales) that are sensitive to SCD morbidity and have the potential to capture changes that are clinically meaningful in the context of patients' day to day lives. In particularly vulnerable cognitive domains, such as executive function, we highlight the advantages of composite over single-test scores within the context of trials. We also identify general (i.e., practice effects, disease heterogeneity) and SCD-specific considerations (i.e., genotype, treatment course, and disease course, including degree of neurologic, pain, and sleep morbidity) for trial measures. Executive function composites hold particular promise as trial endpoints that are clinically meaningful, amenable to change, relatively easy to collect, and can be incorporated into the routine care of patients with SCD in various settings and countries.

Mediators of change in depressed mood following pain rehabilitation among participants with mild, moderate, or severe depressive symptoms

BACKGROUND

Prior research indicates that depression and chronic pain commonly co-exist and impact each other. Interdisciplinary pain rehabilitation programs (IPRPs) have been shown to lead to statistically and clinically significant improvements for patients who report both depressed mood and chronic pain, however there is a gap in the literature regarding the mechanisms by which these improvements occur.

METHODS

This two-site, distinct sample study (Study 1: N = 303, 10-week, individual format, ACT-based program; Study 2: N = 406, 3-week, group format, CBT-based program) evaluated mediators of treatment improvement in depressive symptoms among adult IPRP participants who reported elevated depressive symptoms at program admission and examined treatment mechanisms for depressive symptoms.

RESULTS

Self-reported pain self-efficacy and pain catastrophizing - particularly the helplessness domain - mediated the treatment-related change in depression among IPRP participants with elevated depressive symptoms across the two sites and samples. In one sample, full mediation was achieved while in the other sample, partial mediation was achieved. Participants in both samples showed improvement on all measures.

LIMITATIONS

This study relied on self-report measures of depressive severity and not clinical diagnosis. Results may not generalize to other populations of patients with chronic pain. There was no control condition in either study.

CONCLUSION

Increasing pain self-efficacy and decreasing a sense of helplessness are important treatment targets among IPRP participants who endorse symptoms of depression.

A Randomized Preference Trial Comparing Cognitive-Behavioral Therapy and Yoga for the Treatment of Late-Life Worry: Examination of Impact on Depression, Generalized Anxiety, Fatigue, Pain, Social Participation, and Physical Function

Background

Depression, generalized anxiety, fatigue, diminished physical function, reduced social participation, and pain are common for many older adults and negatively impact quality of life. The purpose of the overall trial was to compare the effects of cognitive-behavioral therapy (CBT) and yoga on late-life worry, anxiety, and sleep; and examine preference and selection effects on these outcomes.

Objective

The present analyses compared effects of the 2 interventions on additional outcomes (depressive symptoms, generalized anxiety symptoms, fatigue, pain interference/intensity, physical function, social participation); and examined whether there are preference and selection effects for these treatments.

Methods

A randomized preference trial of CBT and yoga was conducted in adults ≥60 years who scored ≥26 on the Penn State Worry Questionnaire-Abbreviated (PSWQ-A), recruited from outpatient medical clinics, mailings, and advertisements. Cognitive-behavioral therapy consisted of 10 weekly telephone sessions. Yoga consisted of 20 bi-weekly group yoga classes. Participants were randomized to(1): a randomized controlled trial (RCT) of CBT or yoga (n = 250); or (2) a preference trial in which they selected their treatment (CBT or yoga; n = 250). Outcomes were measured at baseline and post-intervention.

Results

Within the RCT, there were significant between-group differences for both pain interference and intensity. The pain interference score improved more for the CBT group compared with the yoga group [intervention effect of (mean (95% CI) = 2.5 (.5, 4.6), P = .02]. For the pain intensity score, the intervention effect also favored CBT over yoga [.7 (.2, 1.3), P < .01]. Depressive symptoms, generalized anxiety, and fatigue showed clinically meaningful within-group changes in both groups. There were no changes in or difference between physical function or social participation for either group. No preference or selection effects were found.

Conclusion

Both CBT and yoga may be useful for older adults for improving psychological symptoms and fatigue. Cognitive-behavioral therapy may offer even greater benefit than yoga for decreasing pain.

Improving Anxiety Screening in Patients with Turner Syndrome

INTRODUCTION

Turner syndrome (TS) results from a complete or partial loss of the X chromosome and affects 25-50 per 100,000 females. These individuals have characteristic neurocognitive and psychological profiles with an increased lifetime prevalence of mood disorders, such as depression and anxiety. Consensus guidelines recommend the use of psychometrically robust tools to screen for these conditions [Eur J Endocrinol. 2017;177(3):G1-G70 and Gynecol Endocrinol. 2004;19(6):313-9]. We propose a sustainable and informative approach to routine anxiety screening in individuals with TS and describe the prevalence of anxiety, genotype-phenotype associations, and impact of comorbidities on anxiety.

METHODS

We pilot the use of a self-administered version of the validated Pediatric, Parent Proxy, and Adult Patient-Reported Outcomes Measurement Information System (PROMIS®) Anxiety tool during routine visits to the Cincinnati Children's Hospital Medical Center (CCHMC) TS clinic from October 2019 to March 2020.

RESULTS

Ninety-two eligible TS females, ages 8-62 years, received the PROMIS® Anxiety measure. Elevated anxiety scores, ≥1 standard deviation above the T-score mean, were present in 65% of patients (38% mild, 19% moderate, and 8% severe). Results were discussed during the clinic visit, and referral for further evaluation and treatment was offered. There was no apparent genotype-phenotype association among females with anxiety; however, there appeared to be elevated anxiety symptoms (T-score >60) in those with hearing deficits and also in individuals with three or more medical comorbidities. Of the 55% of patients who filled out the acceptability survey, 88% found the process helpful and ∼50% felt that screening should be performed at least every 6 months.

CONCLUSION

Our study demonstrated a high prevalence of anxiety symptoms within a cohort of 92 females with TS. In alignment with current guidelines, these findings indicate the importance of routine neuropsychological assessments for timely recognition and subsequent management of anxiety, especially as milder presentations may otherwise go unnoticed. We have shown that screening tools, such as the PROMIS® Anxiety measure, can be easily utilized by nonmental health care providers (i.e., endocrinologists) who may see TS patients more frequently and be able to initiate impactful discussions surrounding mental health and further referral to subspecialists for expert management.

Targeted fully endoscopic visualized laminar trepanning approach under local anaesthesia for resection of highly migrated lumbar disc herniation

PURPOSE

To introduce a new fully endoscopic visualized laminar trepanning approach with a periendoscopic trephine under local anesthesia for resection of highly migrated lumbar disc herniation (LDH) and report the clinical outcomes of one year follow-up.

METHODS

Twenty-one patients with highly migrated LDH who underwent percutaneous endoscopic lumbar discectomy via the laminar trepanning approach from June 2019 to August 2020 were retrospectively reviewed. Patient-Reported Outcomes Measurement Information System (PROMIS) Short Forms-Pain Interference (PI) and Physical Function (PF) were selected as outcome measures. The operating duration and complication were documented.

RESULTS

The average age of the 21 patients (15 males, 6 females) was 37.8 ± 6.0 years (29-52 years). Disc migration originated from L4/5 in 19 patients, L5/S1 in two patients. The mean operative duration was 54.1 ± 9.0 minutes (42-79 min). All patients were followed up to 12 months after the operation. PROMIS PI T-scores decreased significantly from pre-operatively mean 68.6 ± 2.4 to 54.4 ± 1.9 (P < 0.001) and 47.1 ± 4.3 (P < 0.001) at six weeks and 12 months, respectively. PROMIS PF T-scores improved significantly from pre-operatively mean 26.7 ± 4.7 to 44.3 ± 4.2(P < 0.001) and 58.4 ± 4.0 (P < 0.001) at six weeks and 12 months, respectively. No complications and disc herniation recurrences occurred.

CONCLUSION

The targeted full endoscopic laminar trepanning under local anesthesia with a visualized periendoscopic trephine offers a safe, efficient and cost-effective option for the resection of highly migrated LDH.

Exploring the Feasibility of a Mindfulness-Music Therapy Intervention to Improve Anxiety and Stress in Adolescents and Young Adults with Cancer

CONTEXT

Adolescent and young adults (AYAs) with cancer experience significant psychological distress due to cancer treatment that can persist long after treatment. However, little is known regarding optimal interventions to support the psychosocial needs of AYAs with cancer.

OBJECTIVE

The overall objective of this single arm, longitudinal, pilot study was to determine the feasibility of implementing a mindfulness-based music therapy intervention to improve anxiety and stress in AYAs receiving cancer treatment.

METHODS

AYAs (15 - 39 years old) who were to receive cancer treatment for ≥ eight weeks were recruited from the pediatric, melanoma, sarcoma, breast, lymphoma, and leukemia oncology outpatient centers at Dana-Farber Cancer Institute. The music therapy intervention included four sessions of individual mindfulness-based music therapy in-person or using Zoom over twelve weeks. Prior to-and after the intervention period, participants completed the Patient-Reported Outcomes Measurement Information Anxiety 4a and Perceived Stress Scale. Changes in patient-reported outcomes are compared using Wilcoxon signed-rank tests.

RESULTS

Over ∼14 months, 37 of 93 eligible AYAs were enrolled to the study (39.8% consent rate). Overall, 27 of 37 (73%) participants (Median age=32; 56.8% Female) completed at least two music therapy sessions and the baseline measures and end of study measures. Participation in the mindfulness-based music therapy sessions resulted in significant pre-to-posttest improvements in perceived stress (median change: -4.0, P = 0.013) and non-significant changes in anxiety (median change: -1.9, P = 0.20). Satisfaction and acceptability were highly rated.

CONCLUSIONS

The delivery of a four-session mindfulness-based music therapy intervention to AYAs receiving chemotherapy was feasible and significantly improved perceived stress. These preliminary findings should be confirmed in a randomized controlled trial.

Opioid use and social disadvantage in patients with chronic musculoskeletal pain

BACKGROUND

Historically, marginalized patients were prescribed less opioid medication than affluent, white patients. However, because of persistent differential access to nonopioid pain treatments, this direction of disparity in opioid prescribing may have reversed.

OBJECTIVE

To compare social disadvantage and health in patients with chronic pain who were managed with versus without chronic opioid therapy. It was hypothesized that patients routinely prescribed opioids would be more likely to live in socially disadvantaged communities and report worse health.

DESIGN

Cross-sectional analysis of a retrospective cohort defined from medical records from 2000 to 2019.

SETTING

Single tertiary safety net medical center.

PATIENTS

Adult patients with chronic musculoskeletal pain who were managed longitudinally by a physiatric group practice from at least 2011 to 2015 (n = 1173), subgrouped by chronic (≥4 years) adherent opioid usage (n = 356) versus no chronic opioid usage (n = 817).

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

The primary outcome was the unadjusted between-group difference in social disadvantage, defined by living in the worst national quartile of the Area Deprivation Index (ADI). An adjusted effect size was also calculated using logistic regression, with age, sex, race, and Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference and Physical Function scores as covariates. Secondary outcomes included adjusted differences in health by chronic opioid use (measured by PROMIS).

RESULTS

Patients managed with chronic opioid therapy were more likely to live in a zip code within the most socially disadvantaged national quartile (34.9%; 95% confidence interval [CI] 29.9-39.9%; vs. 24.9%; 95% CI 21.9-28.0%; P < .001), and social disadvantage was independently associated with chronic opioid use (odds ratio [OR] 1.01 per ADI percentile [1.01-1.02]). Opioid use was also associated with meaningfully worse PROMIS Depression (3.8 points [2.4-5.1]), Anxiety (3.0 [1.4-4.5]), and Pain Interference (2.6 [1.7-3.5]) scores.

CONCLUSIONS

Patients prescribed chronic opioid treatment were more likely to live in socially disadvantaged neighborhoods, and chronic opioid use was independently associated with worse behavioral health. Improving access to multidisciplinary, nonopioid treatments for chronic pain may be key to successfully overcoming the opioid crisis.

The Influence of Race, Sex, and Social Disadvantage on Self-reported Health in Patients Presenting With Chronic Musculoskeletal Pain

OBJECTIVE

The aim of the study was to better address sociodemographic-related health disparities. This study examined which sociodemographic variables most strongly correlate with self-reported health in patients with chronic musculoskeletal pain.

DESIGN

This single-center, cross-sectional study examined adult patients, followed by a physiatrist for chronic (≥4 yrs) musculoskeletal pain. Sociodemographic variables considered were race, sex, and disparate social disadvantage (measured as residential address in the worst vs. best Area Deprivation Index national quartile). The primary comparison was the adjusted effect size of each variable on physical and behavioral health (measured by Patient-Reported Outcomes Measurement Information System [PROMIS]).

RESULTS

In 1193 patients (age = 56.3 ± 13.0 yrs), disparate social disadvantage was associated with worse health in all domains assessed (PROMIS Physical Function Β = -2.4 points [95% confidence interval = -3.8 to -1.0], Pain Interference = 3.3 [2.0 to 4.6], Anxiety = 4.0 [1.8 to 6.2], and Depression = 3.7 [1.7 to 5.6]). Black race was associated with greater anxiety than white race (3.2 [1.1 to 5.3]), and female sex was associated with worse physical function than male sex (-2.5 [-3.5 to -1.5]).

CONCLUSIONS

Compared with race and sex, social disadvantage is more consistently associated with worse physical and behavioral health in patients with chronic musculoskeletal pain. Investment to ameliorate disadvantage in geographically defined communities may improve health in sociodemographically at-risk populations.

Digital Mental Health Intervention Plus Usual Care Compared to Usual Care Only and Usual Care Plus In-Person Psychological Counseling for Orthopedic Patients with Symptoms of Depression and/or Anxiety: Cohort Study (Preprint)

Background

Depression and anxiety frequently coexist with chronic musculoskeletal pain and can negatively impact patients’ responses to standard orthopedic treatments. Nevertheless, mental health is not routinely addressed in the orthopedic care setting. If effective, a digital mental health intervention may be a feasible and scalable method of addressing mental health in an orthopedic setting.

Objective

We aimed to compare 2-month changes in mental and physical health between orthopedic patients who received a digital mental health intervention in addition to usual orthopedic care, those who received usual orthopedic care only (without a specific mental health intervention), and those who received in-person care with a psychologist as part of their orthopedic treatment plan.

Methods

In this single-center retrospective cohort study involving ancillary analysis of a pilot feasibility study, 2-month self-reported health changes were compared between a cohort of orthopedic patients who received access to a digital mental health intervention (Wysa) and 2 convenience sample comparison cohorts (patients who received usual orthopedic care without a specific mental health intervention and patients who received in-person care with a psychologist as part of their orthopedic treatment plan). All patients were 18 years or older and reported elevated symptoms of depression or anxiety at an orthopedic clinic visit (Patient-Reported Outcomes Measurement Information System [PROMIS] Depression or Anxiety score ≥55). The digital intervention was a multi-component mobile app that used chatbot technology and text-based access to human counselors to provide cognitive behavioral therapy, mindfulness training, and sleep tools, among other features, with an emphasis on behavioral activation and pain acceptance. Outcomes of interest were between-cohort differences in the 2-month longitudinal changes in PROMIS Depression and Anxiety scores (primary outcomes) and PROMIS Pain Interference and Physical Function scores (secondary outcomes).

Results

Among 153 patients (mean age 55, SD 15 years; 128 [83.7%] female; 51 patients per cohort), patients who received the digital mental health intervention showed clinically meaningful improvements at the 2-month follow-up for all PROMIS measures (mean longitudinal improvement 2.8-3.7 points; P≤.02). After controlling for age and BMI, the improvements in PROMIS Depression, Pain Interference, and Physical Function were meaningfully greater than longitudinal changes shown by patients who received usual orthopedic care (mean between-group difference 2.6-4.8 points; P≤.04). Improvements in PROMIS Physical Function were also meaningfully greater than longitudinal changes shown by patients who received in-person psychological counseling (mean between-group difference 2.4 points; P=.04).

Conclusions

Patients who received a digital mental health intervention as part of orthopedic care reported greater 2-month mean improvements in depression, pain interference, and physical function than patients who received usual orthopedic care. They also reported a greater mean improvement in physical function and comparable improvements in depression, anxiety, and pain interference compared with orthopedic patients who received in-person psychological counseling.

How Should We Measure Social Deprivation in Orthopaedic Patients?

BACKGROUND

Social deprivation negatively affects a myriad of physical and behavioral health outcomes. Several measures of social deprivation exist, but it is unclear which measure is best suited to describe patients with orthopaedic conditions.

QUESTIONS/PURPOSES

(1) Which measure of social deprivation, defined as "limited access to society's resources due to poverty, discrimination, or other disadvantage," is most strongly and consistently correlated with patient-reported physical and behavioral health in patients with orthopaedic conditions? (2) Compared with the use of a single measure alone, how much more variability in patient-reported health does the simultaneous use of multiple social deprivation measures capture?

METHODS

Between 2015 and 2017, a total of 79,818 new patient evaluations occurred within the orthopaedic department of a single, large, urban, tertiary-care academic center. Over that period, standardized collection of patient-reported health measures (as described by the Patient-reported Outcomes Measurement Information System [PROMIS]) was implemented in a staged fashion throughout the department. We excluded the 25% (19,926) of patient encounters that did not have associated PROMIS measures reported, which left 75% (59,892) of patient encounters available for analysis in this cross-sectional study of existing medical records. Five markers of social deprivation were collected for each patient: national and state Area Deprivation Index, Medically Underserved Area Status, Rural-Urban Commuting Area code, and insurance classification (private, Medicare, Medicaid, or other). Patient-reported physical and behavioral health was measured via PROMIS computer adaptive test domains, which patients completed as part of standard care before being evaluated by a provider. Adults completed the PROMIS Physical Function version 1.2 or version 2.0, Pain Interference version 1.1, Anxiety version 1.0, and Depression version 1.0. Children ages 5 to 17 years completed the PROMIS Pediatric Mobility version 1.0 or version 2.0, Pain Interference version 1.0 or version 2.0, Upper Extremity version 1.0, and Peer Relationships version 1.0. Age-adjusted partial Pearson correlation coefficients were determined for each social deprivation measure and PROMIS domain. Coefficients of at least 0.1 were considered clinically meaningful for this purpose. Additionally, to determine the percentage of PROMIS score variability that could be attributed to each social deprivation measure, an age-adjusted hierarchical regression analysis was performed for each PROMIS domain, in which social deprivation measures were sequentially added as independent variables. The model coefficients of determination (r2) were compared as social deprivation measures were incrementally added. Improvement of the r2 by at least 10% was considered clinically meaningful.

RESULTS

Insurance classification was the social deprivation measure with the largest (absolute value) age-adjusted correlation coefficient for all adult and pediatric PROMIS physical and behavioral health domains (adults: correlation coefficient 0.40 to 0.43 [95% CI 0.39 to 0.44]; pediatrics: correlation coefficient 0.10 to 0.19 [95% CI 0.08 to 0.21]), followed by national Area Deprivation Index (adults: correlation coefficient 0.18 to 0.22 [95% CI 0.17 to 0.23]; pediatrics: correlation coefficient 0.08 to 0.15 [95% CI 0.06 to 0.17]), followed closely by state Area Deprivation Index. The Medically Underserved Area Status and Rural-Urban Commuting Area code each had correlation coefficients of 0.1 or larger for some PROMIS domains but neither had consistently stronger correlation coefficients than the other. Except for the PROMIS Pediatric Upper Extremity domain, consideration of insurance classification and the national Area Deprivation Index together explained more of the variation in age-adjusted PROMIS scores than the use of insurance classification alone (adults: r2 improvement 32% to 189% [95% CI 0.02 to 0.04]; pediatrics: r2 improvement 56% to 110% [95% CI 0.01 to 0.02]). The addition of the Medically Underserved Area Status, Rural-Urban Commuting Area code, and/or state Area Deprivation Index did not further improve the r2 for any of the PROMIS domains.

CONCLUSION

To capture the most variability due to social deprivation in orthopaedic patients' self-reported physical and behavioral health, insurance classification (categorized as private, Medicare, Medicaid, or other) and national Area Deprivation Index should be included in statistical analyses. If only one measure of social deprivation is preferred, insurance classification or national Area Deprivation Index are reasonable options. Insurance classification may be more readily available, but the national Area Deprivation Index stratifies patients across a wider distribution of values. When conducting clinical outcomes research with social deprivation as a relevant covariate, we encourage researchers to consider accounting for insurance classification and/or national Area Deprivation Index, both of which are freely available and can be obtained from data that are typically collected during routine clinical care.

Health-related quality of life among United States service members with low back pain receiving usual care plus chiropractic care plus usual care vs usual care alone: Secondary outcomes of a pragmatic clinical trial

Objective

This study examines Patient-Reported Outcome Measurement Information System (PROMIS^®)-29 v1.0 outcomes of chiropractic care in a multi-site, pragmatic clinical trial and compares the PROMIS measures to: 1) worst pain intensity from a numerical pain rating 0–10 scale, 2) 24-item Roland-Morris Disability Questionnaire (RMDQ); and 3) global improvement (modified visual analog scale).

Design

A pragmatic, prospective, multisite, parallel-group comparative effectiveness clinical trial comparing usual medical care (UMC) with UMC plus chiropractic care (UMC+CC).

Setting

Three military treatment facilities

Subjects

750 active-duty military personnel with low back pain

Methods

Linear mixed effects regression models estimated the treatment group differences. Coefficient of repeatability to estimate significant individual change.

Results

We found statistically significant mean group differences favoring UMC+CC for all PROMIS^®-29 scales and the RMDQ score. Area under the curve estimates for global improvement for the PROMIS^®-29 scales and the RMDQ, ranged from 0.79 to 0.83.

Conclusions

Findings from this pre-planned secondary analysis demonstrate that chiropractic care impacts health-related quality of life beyond pain and pain-related disability. Further, comparable findings were found between the 24-item RMDQ and the PROMIS^®-29 v1.0 briefer scales.

Digital mental health intervention for orthopedic patients with symptoms of depression and/or anxiety: Pilot feasibility study

BACKGROUND

Symptoms of depression and anxiety commonly coexist with chronic musculoskeletal pain, and when this occurs, standard orthopedic treatment is less effective. Nevertheless, addressing mental health is not yet a routine part of standard orthopedic treatment, in part due to access related barriers. Digital mental health intervention offers the potential to be a scalable resource that could feasibly be incorporated into orthopedic care.

OBJECTIVE

The primary purpose of this study was to assess the feasibility of introducing a digital mental health intervention (Wysa) within an outpatient orthopedic setting to patients who endorse coexisting symptoms of depression and/or anxiety. The secondary purpose was to perform a preliminary effectiveness analysis of the intervention.

METHODS

In this single-arm, prospective cohort study, participants included adult patients (18 years and older) who presented to a non-surgical orthopedic specialist at a single tertiary care academic center for evaluation of a musculoskeletal condition and who self-reported symptoms of depression and/or anxiety (Patient-Reported Outcomes Measurement Information System (PROMIS) Depression and/or Anxiety score ≥ 55). Enrollment was performed face-to-face by a research coordinator immediately after the participant's encounter with an orthopedic clinician. Participants were provided two months of access to a mobile app called Wysa, which is an established, multi-component digital mental health intervention that uses chatbot technology and text-based access to human counselors to deliver cognitive behavioral therapy, mindfulness training, and sleep tools, among other features. For this study, Wysa access also included novel, behavioral activation based features specifically developed for users with chronic pain. Primary feasibility outcomes included the study recruitment rate, retention rate, and engagement rate with Wysa (defined as engaging with a therapeutic Wysa tool at least once during the study period). Secondary effectiveness outcomes were between-group differences in mean longitudinal PROMIS mental and physical health score changes at two-month follow-up between high Wysa users and low Wysa users, defined by a median split.

RESULTS

The recruitment rate was 61/208 (29%), retention rate was 51/61 (84%), and engagement rate was 44/61 (72%). Compared to low users, high Wysa users achieved greater improvement in PROMIS Anxiety (between-group difference -4.2 points [95% CI -8.1 to -0.2], P=.044) at two-month follow-up. Between-group differences in PROMIS Depression (-3.2 points [-7.5 to 1.2], P=.15) and Pain Interference (-2.3 points [-6.3 to 1.7], P=.26) favored high users but did not meet statistical significance. Improvements in PROMIS Physical Function were comparable between groups.

CONCLUSIONS

Delivery of a digital mental health intervention within the context of orthopedic care is feasible and demonstrates potential to improve mental health and pain-related impairment to a clinically meaningful degree. Participants' engagement rates exceeded industry standards, and additional opportunities to improve recruitment and retention were identified. Further pilot study followed by a definitive, randomized controlled trial is warranted.

Free-Living User Perspectives on Musculoskeletal Pain and Patient-Reported Mobility With Passive and Powered Prosthetic Ankle-Foot Components: A Pragmatic, Exploratory Cross-Sectional Study

Introduction

Studies with a powered prosthetic ankle-foot (PwrAF) found a reduction in sound knee loading compared to passive feet. Therefore, the aim of the present study was to determine whether anecdotal reports on reduced musculoskeletal pain and improved patient-reported mobility were isolated occurrences or reflect a common experience in PwrAF users.

Methods

Two hundred and fifty individuals with transtibial amputation (TTA) who had been fitted a PwrAF in the past were invited to an online survey on average sound knee, amputated side knee, and low-back pain assessed with numerical pain rating scales (NPRS), the PROMIS Pain Interference scale, and the PLUS-M for patient-reported mobility in the free-living environment. Subjects rated their current foot and recalled the ratings for their previous foot. Recalled scores were adjusted for recall bias by clinically meaningful amounts following published recommendations. Statistical comparisons were performed using Wilcoxon's signed rank test.

Results

Forty-six subjects, all male, with unilateral TTA provided data suitable for analysis. Eighteen individuals (39%) were current PwrAF users, whereas 28 subjects (61%) had reverted to a passive foot. After adjustment for recall bias, current PwrAF users reported significantly less sound knee pain than they recalled for use of a passive foot (−0.5 NPRS, p = 0.036). Current PwrAF users who recalled sound knee pain ≥4 NPRS with a passive foot reported significant and clinically meaningful improvements in sound knee pain (−2.5 NPRS, p = 0.038) and amputated side knee pain (−3 NPRS, p = 0.042). Current PwrAF users also reported significant and clinically meaningful improvements in patient-reported mobility (+4.6 points PLUS-M, p = 0.016). Individuals who had abandoned the PwrAF did not recall any differences between the feet.

Discussion

Current PwrAF users reported significant and clinically meaningful improvements in patient-reported prosthetic mobility as well as sound knee and amputated side knee pain compared to recalled mobility and pain with passive feet used previously. However, a substantial proportion of individuals who had been fitted such a foot in the past did not recall improvements and had reverted to passive feet. The identification of individuals with unilateral TTA who are likely to benefit from a PwrAF remains a clinical challenge and requires further research.

Prospective, Single-blind, Randomized Controlled Trial to Evaluate the Effectiveness of a Digital Exercise Therapy Application Compared With Conventional Physical Therapy for the Treatment of Nonoperative Knee Conditions

Objective

To evaluate the effectiveness and adherence of a home exercise therapy program using a digital exercise therapy application (DETA) compared with conventional physical therapy (PT).

Design

Parallel group, randomized controlled trial.

Setting

Two clinics in a tertiary care academic center.

Participants

Participants (N=60) were enrolled within 1 week after a provider visit for knee pain. Inclusion criteria: age 18-75 years, knee pain diagnosis, and clinician-prescribed PT.

Interventions

Participants were randomized to complete either an 8-week intervention of conventional PT (enrolled n=29; complete n=26) or the DETA (enrolled n=31; completed n=24).

Main Outcome Measures

Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI) and Physical Function (PF) scores implemented via computer adaptive tests; number of exercise sessions completed per week (adherence).

Results

Compared with the PT group, the DETA group reported significant decreases in PROMIS-PI scores (−6.1±6.7 vs −1.5±6.6, P<.05, d=0.78) and increases in PROMIS-PF scores (6.0±6.6 vs −0.8±5.8, P<.01, d=0.89) after 8 weeks. No group differences in adherence were observed (P>.05).

Conclusions

Use of this DETA resulted in greater pain and functional improvements compared with PT, with no differences in adherence. It is possible this application may be a viable alternative to conventional PT in certain cases. A larger sample from various geographic locations is needed to improve generalizability and for subgroup analysis. Further investigation is warranted to determine the factors responsible for the differences observed between the groups.

Microprocessor feet improve prosthetic mobility and physical function relative to non-microprocessor feet

Introduction: The clinical benefits associated with the microprocessor regulation of prosthetic ankle position and resistance have largely been reported through manufacturer conducted research in controlled laboratory environments. Measures with greater ecological validity are needed. This study aimed to understand if there are differences in physical function and mobility outcomes as patients transitioned from a non-Microprocessor to Microprocessor Feet. Method: A retrospective analysis of patient outcomes was performed. Patient-reported benefits associated with the adoption of such prosthetic foot-ankle mechanisms were collected from 23 individuals through the longitudinal use of a custom short form of the Patient-Reported Outcomes Measurement Information System-Physical Function and individual items from the Prosthesis Evaluation Questionnaire. Results: The impact of Microprocessor Feet upon physical function and mobility were observed in a significant increase in physical function (mean increase in t-score of 5.4 ± 1.25; p = .0004) and significant improvements in several mobility items. Conclusions: Collectively, these measures support the beneficial impact of Microprocessor Feet on improving socket comfort, reducing back pain, improving sit to stand transfers and enhancing hill ascent and descent as well as stair negotiation.

Online Mindfulness-Based Interventions for Well-Being: Randomized Comparative Effectiveness Trial (Preprint)

Background

Mindfulness can improve overall well-being by training individuals to focus on the present moment without judging their thoughts. However, it is unknown how much mindfulness practice and training are necessary to improve well-being.

Objective

The primary aim of this study was to determine whether a standard 8-session web-based mindfulness-based cognitive therapy (MBCT) program, compared with a brief 3-session mindfulness intervention, improved overall participant well-being. In addition, we sought to explore whether the treatment effects differed based on the baseline characteristics of the participants (ie, moderators).

Methods

Participants were recruited from 17 patient-powered research networks, web-based communities of stakeholders interested in a common research area. Participants were randomized to either a standard 8-session MBCT or a brief 3-session mindfulness training intervention accessed on the web. The participants were followed for 12 weeks. The primary outcome of the study was well-being, as measured by the World Health Organization—Five Well-Being Index. We hypothesized that MBCT would be superior to a brief mindfulness training.

Results

We randomized 4411 participants, 3873 (87.80%) of whom were White and 3547 (80.41%) of female sex assigned at birth. The mean baseline World Health Organization—Five Well-Being Index score was 50.3 (SD 20.7). The average self-reported well-being in each group increased over the intervention period (baseline to 8 weeks; model-based slope for the MBCT group: 0.78, 95% CI 0.63-0.93, and brief mindfulness group: 0.76, 95% CI 0.60-0.91) as well as the full study period (ie, intervention plus follow-up; baseline to 20 weeks; model-based slope for MBCT group: 0.41, 95% CI 0.34-0.48; and brief mindfulness group: 0.33, 95% CI 0.26-0.40). Changes in self-reported well-being were not significantly different between MBCT and brief mindfulness during the intervention period (model-based difference in slopes: −0.02, 95% CI −0.24 to 0.19; P=.80) or during the intervention period plus 12-week follow-up (−0.08, 95% CI −0.18 to 0.02; P=.10). During the intervention period, younger participants (P=.05) and participants who completed a higher percentage of intervention sessions (P=.005) experienced greater improvements in well-being across both interventions, with effects that were stronger for participants in the MBCT condition. Attrition was high (ie, 2142/4411, 48.56%), which is an important limitation of this study.

Conclusions

Standard MBCT improved well-being but was not superior to a brief mindfulness intervention. This finding suggests that shorter mindfulness programs could yield important benefits across the general population of individuals with various medical conditions. Younger people and participants who completed more intervention sessions reported greater improvements in well-being, an effect that was more pronounced for participants in the MBCT condition. This finding suggests that standard MBCT may be a better choice for younger people as well as treatment-adherent individuals.

Patient-Reported Outcomes of Yearly Imaging Surveillance in Patients Following Endovascular Aortic Aneurysm Repair

Little is known about the impact of standardized imaging surveillance on anxiety levels and well-being of patients after endovascular aortic aneurysm repair (EVAR). We hypothesize that patient anxiety levels increase just before receiving the imaging results compared with standard anxiety levels.

METHODS

Prospective cohort study from November 2018 to May 2020 including post-EVAR patients visiting the outpatient clinics of 4 Dutch hospitals for imaging follow-up. The Patient-Reported Outcomes Measurement Information System (PROMIS) was used. Patients completed the PROMIS Anxiety v1.0 Short Form (SF) 4a, PROMIS-Global Health Scale v1.2, and PROMIS-Physical Function v1.2 SF8b at 2 time points: prior to the result of the imaging study (T1: pre-visit) and 6-8 months later (T2: reference measurement). Mean T-scores at T1 were compared to T2, and T2 to the general 65+ Dutch population.

RESULTS

Altogether 342 invited patients were eligible, 214 completed the first questionnaire, 189 returned 2 completed questionnaires and 128 patients did not participate. Out of 214 respondents, 195 were male (91.1%) and the mean (standard deviation) age was 75.2 (7.0) years. There were no significant differences between T1 and T2 in anxiety levels (0.48; 95% confidence interval[CI] -0.42-1.38), global mental health (0.27; 95% CI -0.79-0.84), global physical health (0.10; 95% CI -0.38-1.18) and physical function (0.53; 95% CI -0.26-1.32). Compared with the 65+ Dutch population, at T2 patients experienced more anxiety (3.8; 95% CI 2.96-5.54), had worse global physical health (-3.2; 95% CI -4.38 - -2.02) and physical function (-2.4; 95% CI -4.00 - -0.80). Global mental health was similar (-1.0; 95% CI -2.21 - 0.21).

CONCLUSIONS

Post-EVAR patients do not experience more anxiety just before receiving surveillance imaging results than outside this period, but do suffer from more anxiety and worse physical outcomes than the 65+ Dutch population.

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.

Validation of PROMIS Profile-29 in adults with hemophilia in the Netherlands

BACKGROUND

The Patient-Reported Outcomes Measurement Information System (PROMIS) Profile-29 questionnaire is widely used worldwide, but it has not yet been validated in the Netherlands, nor in persons with hemophilia.

OBJECTIVE

To validate the Dutch-Flemish version of the PROMIS-29 Profile v2.01 in adults with hemophilia.

METHODS

Dutch males with hemophilia (all severities) completed questionnaires that contained sociodemographic and clinical characteristics, the PROMIS-29, RAND-36, and the Hemophilia Activities List (HAL). Structural validity of each subscale was assessed with confirmatory factor analysis (CFA). Internal consistency was calculated for each subscale with sufficient model fit in CFA. Construct validity was assessed by testing hypotheses about (1) correlations of each PROMIS-29 subscale with corresponding scales of RAND-36 and domains of HAL, and (2) mean differences in T-scores between subgroups with different hemophilia severities, self-reported joint impairment, and HIV infection status. We considered ≥75% of data in accordance with the hypotheses evidence for construct validity.

RESULTS

In total, 770 persons with hemophilia participated in this cross-sectional study. CFA revealed sufficient structural validity for five subscales: Physical Function, Depression, Sleep Disturbance, Ability to Participate in Social Roles and Activities, and Pain Interference. Internal consistency was high and Cronbach's alpha ranged from 0.79 for Sleep Disturbance to 0.96 for Pain Interference. Differences between clinical subgroups were in the expected direction. Construct validity was confirmed for Physical Function, Anxiety, Depression, Fatigue, Sleep Disturbance, and Pain Intensity.

CONCLUSION

This study revealed sufficient evidence for structural validity, internal consistency, and construct validity for most PROMIS Profile-29 subscales among people with hemophilia in the Netherlands.

Triangulation of multiple meaningful change thresholds for patient-reported outcome scores

PURPOSE

The notion of what constitutes meaningful differences or changes in patient-reported outcome scores is represented by meaningful change thresholds (MCTs). Applying multiple methods to estimate MCTs inevitably results in a range of estimates; however, a single estimate or small range is sought in practice to enable consistent interpretation of scores. While current recommendations for triangulation are appropriate in principle, the vital step of moving from all estimates to a value or small range lacks clarity and is subjective in nature. This article aims to review current triangulation approaches and provide more robust recommendations than what is currently available.

METHODS

Current approaches to perform triangulation are described and discussed. Anchor-based estimates are focussed upon due to their recognition as the most valid and developed approach. Recommendations for triangulation are provided.

RESULTS

A correlation-weighted average of MCT estimates is recommended to triangulate multiple MCT estimates derived from a single study into a single value, where increased weighting is given to stronger anchor measures. The choice of method to triangulate estimates from several published studies is highly dependent on the availability of information within the publications. MCTs designed for between-group differences, within-group changes, and within-individual changes should be considered separately.

CONCLUSION

The recommendations within this article provide a reliable and transparent approach to triangulation when a single value is sought, based on meta-analytic approaches. This approach is preferable to a simple mean of estimates where all are weighted equally, or through 'eyeballing' plotted estimates which is unreliable. We encourage researchers to adopt these methods, but to remain aware of the limitations within each method and further nuances in study design that result in heterogeneity. Sensitivity analyses with a range of plausible values are encouraged; however, the recommendations provide a suitable starting value for inferences. Unresolved issues in triangulation, requiring further exploration, are highlighted.

Multidimensional Perioperative Recovery Trajectories in a Mixed Surgical Cohort: A Longitudinal Cluster Analysis Utilizing National Institutes of Health Patient-Reported Outcome Measurement Information System Measures

BACKGROUND

Pain trajectories have been described in numerous surgical settings where preoperative characteristics have been used to predict trajectory membership. Suboptimal pain intensity trajectories have been linked to poor longitudinal outcomes. However, numerous biopsychosocial modulators of postoperative pain may also have distinct longitudinal trajectories that may inform additional targets to improve postoperative recovery.

METHODS

Patients undergoing total joint arthroplasty, thoracic surgery, spine surgery, major abdominal surgery, or mastectomy completed Patient Reported Outcome Measurement Information System (PROMIS) measures and additional scales preoperatively and at 1 week, 2 weeks, 1 month, 3 months, and 6 months postoperatively. A k-means clustering for longitudinal data was utilized to explore and describe distinct pain impact (PROMIS Pain Interference and Physical Function) trajectories and associated changes in additional biopsychosocial measures. Follow-up analyses examined participant demographics and clinical characteristics associated with trajectory memberships.

RESULTS

Three postoperative biopsychosocial symptom clusters were identified across all patients (n = 402): low (35%), average (47%), and high (18%) performance cluster trajectories. Participants undergoing total knee arthroplasty (TKA), spinal surgery, reporting presurgical opioid use, and higher pain catastrophizing scale scores were found to be associated with the low performance trajectory. Patients within the low performance trajectory, while demonstrating small improvements by 6 months, remained mild to moderately impaired in both pain impact and physical health outcomes. Alternatively, participants in the average performance trajectory demonstrated improvement in pain impact to population norms compared to baseline and demonstrated continued improvement across physical and psychological outcomes. Patients within the high performance cluster started within population norms across all measures at baseline and returned to baseline or exceeded baseline values by 6 months postoperatively. Self-reported opioid utilization was significantly higher in the low performance cluster across all time points. While a larger proportion of average performance patients reported opioid utilization during the first postoperative month compared to the high performance cluster, no differences were detected at 6 months postoperatively between these 2 clusters.

CONCLUSIONS

These pain impact trajectories build upon previous unidimensional pain intensity trajectories and suggest that additional distinct biopsychosocial measures may have unique trajectories related to cluster assignment. Additionally, these findings highlight the importance of continued pain impact surveillance through the perioperative recovery period to detect patients at risk of experiencing a poor trajectory and subsequently poor longitudinal health outcomes.

Psychoeducational Interventions for Caregivers of Persons With Multiple Sclerosis: Protocol for a Randomized Trial

Background

Of the approximately 1 million people living with multiple sclerosis in the United States, more than half receive informal, unpaid care or support from family or friends (caregivers). These caregivers report high levels of stress, anxiety, and negative emotions. Few researchers have conducted psychoeducational interventions for these caregivers.

Objective

This paper presents a protocol for a randomized clinical trial that aims to test the efficacy of two interventions for improving stress, anxiety, depression, and negative emotions for caregivers of persons with multiple sclerosis.

Methods

Participants included any self-identified family or friend caregiver of a person with multiple sclerosis. Data collection began in April 2021 and is expected to continue until November 2021. Participants will be randomized to receive either a website-only or a website-coaching intervention delivered for 6 weeks. Data will be collected at baseline, 6 weeks after baseline (after delivery of intervention), and 6 weeks later.

Results

The protocol was approved by the institutional review board of the Case Western Reserve University on January 21, 2021 (protocol 20201484). As of May 2021, 66 participants were enrolled.

Conclusions

Our findings will have implications for identifying the efficacy of two types of interventions developed for caregivers of persons with multiple sclerosis to reduce negative psychological outcomes associated with caregiving.

Patients with Clinically Elevated Depressive Symptoms Report Improvements in Mood, Pain, and Functioning following Participation in Interdisciplinary Pain Rehabilitation

OBJECTIVE

Chronic pain and depression frequently co-occur and exacerbate one another; therefore, it is important to treat both conditions to improve patient outcomes. The current study evaluates an interdisciplinary pain rehabilitation program (IPRP) with respect to the following questions: 1) How do clinically elevated depressive symptoms impact pain-related treatment outcomes? and 2) To what extent does IPRP participation yield reliable and clinically significant change in depressed mood?

METHODS

Participants in this study included 425 adults who engaged in a 10-week IPRP and completed self-report measures of pain, mood, and functioning at intake and discharge. Participants were categorized into 4 groups based on self-reported depressive symptoms (PROMIS Depression): within normal limits (WNL; n = 121), Mild (n = 115), Moderate (n = 153), and Severe (n = 36).

RESULTS

Participants reported significant improvement in pain, pain-related life interference, health-related quality of life, pain catastrophizing, and depressed mood regardless of initial symptom level. In addition, 43.4% of patients with Mild, Moderate, or Severe depressed mood reported reliable and clinically significant improvement in depressive symptoms and 30.3% were in remission at the end of treatment.

CONCLUSIONS

These findings support the assertion that IPRPs represent an effective treatment for patients with comorbid chronic pain and depression and that participation is associated with improvement in both conditions.

Impact of the first wave of the COVID-19 pandemic on systemic lupus erythematosus patients: Results from a multi-center prospective cohort

OBJECTIVE

The aim of this study was to evaluate the initial impact of the COVID-19 pandemic on individuals with systemic lupus erythematosus (SLE).

METHODS

Patients with SLE participating in a multi-center longitudinal cohort study in New York and Boston were invited to complete a supplemental web-based questionnaire in the summer of 2020. Participants completed standardized patient-reported outcome (PRO) measures and a combination of Likert scale and open-ended questions exploring the impact of the COVID-19 pandemic on their health and access to health care. Changes in PROs were evaluated with paired t-tests and frequencies of worsened symptoms were calculated. A thematic qualitative analysis was conducted on free text responses.

RESULTS

Of 97 patients invited, 63 (65%) completed a supplemental questionnaire. Nearly 50% of respondents exhibited increases in anxiety (47.5%) and depression (48.3%) and over 40% scored worse in measures of pain interference, fatigue, and cognitive abilities. Respondents with pre-existing diagnoses of anxiety did not differ from other participants in PRO scores, but were more than three times as likely to report worsened health status. Patients denied difficulties accessing medications (85%) or medical care (84%) and over 50% participated in telehealth visits. Anxiety and increased health risks due to immunosuppression were recurring themes in free text responses.

CONCLUSIONS

SLE patients experienced a significant physical and emotional toll in the initial months of the COVID-19 pandemic. Comprehensive patient-centered care, including monitoring and addressing anxiety and health-related quality of life, is critical to improving health outcomes in this population during the ongoing health crisis.

Clinical Profiles of Concurrent Cannabis Use in Chronic Pain: A CHOIR Study

OBJECTIVE

Despite evidence of the analgesic benefits of cannabis, there remains a relative scarcity of research on the short- and long-term effects of cannabis use in individuals with chronic pain.

DESIGN

The current study is a secondary analysis of clinical data from the Collaborative Health Outcomes Information Registry (CHOIR).

SETTING

Data were drawn from a cohort of patients of a multidisciplinary tertiary care pain clinic.

SUBJECTS

The study sample consisted of data from 7,026 new patient visits from CHOIR; of these, 1,668 patients with a follow-up time point within 180 days were included in a longitudinal analysis.

METHODS

Clinical data were analyzed to characterize cross-sectional differences in pain and indicators of psychological and physical function according to self-reported, concurrent cannabis use. Additionally, a propensity score-weighted longitudinal analysis was conducted, examining cannabis use as a predictor of changes in clinical variables across time.

RESULTS

Cross-sectional analyses suggested significantly poorer sleep and significantly higher intensities of pain, emotional distress, and physical and social dysfunction in patients reporting ongoing cannabis use; however, these differences were relatively small in magnitude. However, no differences between cannabis users and nonusers in terms of longitudinal changes in clinical variables were noted.

DISCUSSION

Our results are among the first to examine concurrent cannabis use as a prognostic variable regarding trajectories of pain-related variables in tertiary care. Future studies may benefit from examining the effect of cannabis initiation, concurrent medication use, and specific aspects of cannabis use (dose, duration of use, or cannabis type) on clinical outcomes.

Determining validity, discriminant ability, responsiveness, and minimal clinically important differences for PROMIS in adult spinal deformity

OBJECTIVE

The aim of this study was to determine the concurrent validity, discriminant ability, and responsiveness of the Patient-Reported Outcomes Measurement Information System (PROMIS) in adult spinal deformity (ASD) and to calculate minimal clinically important differences (MCIDs) for PROMIS scores.

METHODS

The authors used data obtained in 186 surgical patients with ASD. Concurrent validity was determined through correlations between preoperative PROMIS scores and legacy measure scores. PROMIS discriminant ability between disease severity groups was determined using the preoperative Oswestry Disability Index (ODI) value as the anchor. Responsiveness was determined through distribution- and anchor-based methods, using preoperative to postoperative changes in PROMIS scores. MCIDs were estimated on the basis of the responsiveness analysis.

RESULTS

The authors found strong correlations between PROMIS Pain Interference and ODI and the Scoliosis Research Society 22-item questionnaire Pain component; PROMIS Physical Function and ODI; PROMIS Anxiety and Depression domains and the 12-Item Short Form Health Survey version 2, Physical and Mental Components, Scoliosis Research Society 22-item questionnaire Mental Health component (anxiety only), 9-Item Patient Health Questionnaire (anxiety only), and 7-Item Generalized Anxiety Disorder questionnaire; PROMIS Fatigue and 9-Item Patient Health Questionnaire; and PROMIS Satisfaction with Participation in Social Roles (i.e., Social Satisfaction) and ODI. PROMIS discriminated between disease severity groups in all domains except between none/mild and moderate Anxiety, with mean differences ranging from 3.7 to 8.4 points. PROMIS showed strong responsiveness in Pain Interference; moderate responsiveness in Physical Function and Social Satisfaction; and low responsiveness in Anxiety, Depression, Fatigue, and Sleep Disturbance. Final PROMIS MCIDs were as follows: -6.3 for Anxiety, -4.4 for Depression, -4.6 for Fatigue, -5.0 for Pain Interference, 4.2 for Physical Function, 5.7 for Social Satisfaction, and -3.5 for Sleep Disturbance.

CONCLUSIONS

PROMIS is a valid assessment of patient health, can discriminate between disease severity levels, and shows responsiveness to changes after ASD surgery. The MCIDs provided herein may help clinicians interpret postoperative changes in PROMIS scores, taking into account the fact that they are pending external validation.

The PROMISⓇ-Plus-Osteoarthritis of the Knee (OAK) profile measure integrates generic and condition-specific content to enhance relevance and efficiency

OBJECTIVE

The Patient-Reported Outcomes Measurement Information System (PROMIS)-Plus-Osteoarthritis of the Knee (OAK) profile integrates universal PROMIS items with knee-specific items across 13 domains. We evaluated the psychometric properties of a subset of six domains associated with quality of life in people with OAK.

STUDY DESIGN AND SETTING

In a cross-sectional study of OAK patients (n=600), we estimated reliability using Pearson and Spearman correlations with Knee Injury and Osteoarthritis Outcome Score (KOOS) subscores and known-groups validity with PROMIS Global Health. Measure responsiveness was tested via paired t-tests in a longitudinal study (n=238), pre/post total knee replacement.

RESULTS

Across the six domains, internal consistency reliability (Cronbach's alpha) was 0.77-0.95 and test-retest reliability (intraclass correlation coefficients) was ≥0.90. Correlations with Knee Injury and Osteoarthritis Outcome Score (KOOS) subscores and PROMIS Global supported convergent and divergent validity. Known-groups validity testing revealed better scores in all domains for high vs. low global status groups, and knee-specific items added value in physical function and pain. All domains reflected (p<0.001) better health status scores at follow up.

CONCLUSION

The six PROMIS-Plus-OAK profile domains demonstrated good psychometric characteristics. The measure integrates universal and knee-specific content to provide enhanced relevance, measurement precision and efficient administration for patient care and clinical research.

Is Social Deprivation Associated with PROMIS Outcomes After Upper Extremity Fractures in Children?

BACKGROUND

We previously found that social deprivation was associated with worse perceived function and pain among children presenting with upper extremity fractures. We performed the current study to determine whether this differential in outcome scores would resolve after children received orthopaedic treatment for their fractures. This was needed to understand whether acute pain and impaired function were magnified by worse social deprivation or whether social deprivation was associated with differences in health perception even after injury resolution.

QUESTIONS/PURPOSES

Comparing patients from the least socially deprived national quartile and those from the most deprived quartile, we asked: (1) Are there differences in age, gender, race, or fracture location among children with upper extremity fractures? (2) After controlling for relevant confounding variables, is worse social deprivation associated with worse self-reported Patient-Reported Outcomes Measurement Information System (PROMIS) scores before and after the treatment of pediatric upper extremity fractures? (3) Is social deprivation associated with PROMIS score improvements as a result of fracture treatment?

METHODS

In this this retrospective, comparative study, we considered data from 1131 pediatric patients (aged 8 to 17 years) treated nonoperatively at a single tertiary academic medical center for isolated upper extremity fractures between June 2016 and June 2017. We used the Area Deprivation Index to define the patient's social deprivation by national quartiles to analyze those in the most- and least-deprived quartiles. After excluding patients with missing zip codes (n = 181), 18% (172 of 950) lived in the most socially deprived national quartile, while 31% (295 of 950) lived in the least socially deprived quartile. Among these 467 patients in the most- and least-deprived quartiles, 28% (129 of 467) were excluded for lack of follow-up and 9% (41 of 467) were excluded for incomplete PROMIS scores. The remaining 297 patients were analyzed (107 most-deprived quartile, 190 least-deprived quartile) longitudinally in the current study; they included 237 from our initial cross-sectional investigation that only considered reported health at presentation (60 patients added and 292 removed from the 529 patients in the original study, based on updated Area Deprivation Index quartiles). The primary outcomes were the self-completed pediatric PROMIS Upper Extremity Function, Pain Interference, and secondarily PROMIS Peer Relationships computer-adaptive tests. In each PROMIS assessment, higher scores indicated more of that domain (such as, higher function scores indicate better function but a higher pain score indicates more pain), and clinically relevant differences were approximately 3 points. Bivariate analysis compared patient age, gender, race, fracture type, and PROMIS scores between the most- and least-deprived groups. A multivariable linear regression analysis was used to determine factors associated with the final PROMIS scores.

RESULTS

Between the two quartiles, the only demographic and injury characteristic difference was race, with Black children being overrepresented in the most-deprived group (most deprived: white 53% [57 of 107], Black 45% [48 of 107], other 2% [2 of 107]; least deprived: white 92% [174 of 190], Black 4% [7 of 190), other 5% [9 of 190]; p < 0.001). At presentation, accounting for patient gender, race, and fracture location, the most socially deprived quartile remained independently associated with the initial PROMIS Upper Extremity (β 5.8 [95% CI 3.2 to 8.4]; p < 0.001) scores. After accounting for patient gender, race, and number of days in care, we found that the social deprivation quartile remained independently associated with the final PROMIS Upper Extremity (β 4.9 [95% CI 2.3 to 7.6]; p < 0.001) and Pain Interference scores (β -4.4 [95% CI -2.3 to -6.6]; p < 0.001). Social deprivation quartile was not associated with any differential in treatment impact on change in PROMIS Upper Extremity function (8 ± 13 versus 8 ± 12; mean difference 0.4 [95% CI -3.4 to 2.6]; p = 0.79) or Pain Interference scores (8 ± 9 versus 6 ± 12; mean difference 1.1 [95% CI -1.4 to 3.5]; p = 0.39) from presentation to the conclusion of treatment.

CONCLUSION

Delivering upper extremity fracture care produces substantial improvement in pain and function that is consistent regardless of a child's degree of social deprivation. However, as social deprivation is associated with worse perceived health at treatment initiation and conclusion, prospective interventional trials are needed to determine how orthopaedic surgeons can act to reduce the health disparities in children associated with social deprivation. As fractures prompt interaction with our health care system, the orthopaedic community may be well placed to identify children who could benefit from enrollment in proven community health initiatives or to advocate for multidisciplinary care coordinators such as social workers in fracture clinics.

Evaluation of transforaminal epidural steroid injections for discogenic axial lumbosacral back pain utilizing PROMIS as an outcome measure

BACKGROUND CONTEXT

Discogenic lumbosacral back pain continues to present a challenging clinical entity with limited, controversial therapeutic options. No study to date has evaluated the efficacy of fluoroscopically guided transforaminal epidural steroid injections (TFESI) in a homogenous patient population with axial lumbosacral back pain from discogenic pathology utilizing strict, explicitly clinical and radiographic criteria. Additionally, there is a paucity of published data utilizing Patient Reported Outcome Measurement Information System (PROMIS) scores as an outcome measure for interventional spine procedures.

PURPOSE

Evaluate the therapeutic effect of TFESIs in a specific subset of patients with discogenic axial lumbosacral back pain. Investigate PROMIS as an outcome measure for interventional spine procedures targeting focal degenerative spinal pathology.

STUDY DESIGN/SETTING

Retrospective review of patients presenting to a multidisciplinary, tertiary academic spine center.

PATIENT SAMPLE

Three thousand eight hundred eighty-one patients were screened for inclusion. A total of 26 patients with discogenic axial low back, based on strict clinical and radiographic criteria, underwent TFESIs. All patients had axial low back pain without radicular pain, ≥3 clinical features of discogenic pain, corroborative radiographic features of active discogenic pathology on lumbar spine magnetic resonance imaging without confounding spinal pathology.

OUTCOME MEASURES

PROMIS Pain Interference (PI) v1.1, PROMIS Physical Function (PF) v1.2/v2.0, and PROMIS Depression (D) v1.0 outcome scores were collected at baseline and postprocedure follow-up.

METHODS

Query of an institutional, patient reported outcome database and subsequent retrospective review of electronic medical records was performed. Statistical analysis comparing baseline and postprocedural PROMIS outcome scores and correlation between these instruments was performed. Additionally, an exploratory investigation of minimal clinically important difference achievement rates was performed.

RESULTS

Analysis determined a statistically significant improvement in PROMIS PI (p=.017, 95% CI=-8.02 to -1.82) and PROMIS PF (p=.003, 95% CI=0.91-8.72) scores after treatment with TFESIs. At post treatment time points, TFESI had medium effect size on pain (d=0.55) and function (d=0.59). Change in PROMIS D scores (p=.488, 95% CI -1.74-3.54; d=.08) did not demonstrate statistical significance. Pearson correlation demonstrated a moderate negative correlation (r=-0.544, p=.004) between PROMIS PF with PROMIS PI. Correlation between PROMIS PF (r=-0.239, p=.24) and PROMIS PI (r=0.198, p=.33) with PROMIS D was not significant. Fourteen (53.8%) and 9 (34.6%) subjects achieved minimum clinically important difference (MCID) for PROMIS PI and PROMIS PF, respectively. Nine subjects (34.6%) achieved MCID for PROMIS D despite not otherwise reaching statistical significance otherwise.

CONCLUSIONS

Utilizing PROMIS as an outcome measure, discogenic axial lumbosacral back pain patients appear to benefit from TFESI in terms of pain and physical function. This study contributes to the growing body of literature utilizing PROMIS scores in patients with clinical sequelae of degenerative spinal pathology; however, prospective studies are needed.

Videoconference Intervention for Distance Caregivers of Patients With Cancer: A Randomized Controlled Trial

PURPOSE

Approximately 20% of caregivers (CGs) live > 1 hour away from the patient and are considered distance caregivers (DCGs) who often report higher distress and anxiety than local CGs. The purpose of this study was to test the effectiveness of an intervention aimed at reducing anxiety and distress in DCGs of patients with cancer.

METHODS

This randomized controlled trial enrolled DCGs of patients with all cancer types who were being seen monthly by oncologists in outpatient clinics. There were three arms of the intervention delivered over a 4-month period: arm 1 (a) received 4 monthly videoconference-tailored coaching sessions with an advanced practice nurse or social worker focused on information and support, (b) participated in patient's appointments with the oncologist via videoconference over the 4-month study period, and (c) had access to a website designed for DCGs. Arm 2 did not receive the coaching sessions but received the other two components, and arm 3 received access to the DCG website only.

RESULTS

There were 302 DCGs who provided pre- and postintervention data. There were significant anxiety by group (P = .028 and r = 0.16) and distress by group interactions (P = .014 and r = 0.17). Arm 1 had the greatest percentage of DCGs who demonstrated improvement in anxiety (18.6%) and distress (25.2%).

CONCLUSION

Coaching and use of videoconference technology (to join the DCG into the patient-oncologist office visit) were effective in reducing both anxiety and distress for DCGs. These components could be considered for local CGs who-with COVID-19-are unable to accompany the patient to oncologist visits.

Translation and cross-cultural adaptation of Nepali versions of the Patient-Reported Outcomes Measurement Information System (PROMIS®) Pain Intensity, Pain Interference, Pain Behavior, Depression, and Sleep Disturbance short forms in chronic musculoskeletal pain

PURPOSE

The Patient-Reported Outcomes Meaurement Information System (PROMIS®) measures have been translated into many languages and have been shown to have strong measurement properties across a wide range of clinical conditions. However, Nepali translations of the PROMIS short forms are not yet available. The aim of this study was to translate and cross-culturally adapt the PROMIS Pain Intensity, Pain Interference, Pain Behavior, Depression, and Sleep Disturbance short forms into Nepali.

METHODS

We used the Functional Assessment of Chronic Illness Therapy (FACIT) translation methodology, which incorporated two forward translations, synthesis of the translations, a back-translation, and three independent reviews, harmonization, cognitive debriefing, revisions, and proof reading. The translation and review teams were fluent in Nepali and English and represented five different countries and four continents. We evaluated the short forms for comprehensibility and relevance (two key aspects of the content validity of an instrument), conducting cognitive debriefing with six adults with chronic musculoskeletal pain, in compliance with recommendations by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). The final version was proofread by two native Nepali speakers before and three new proofreaders after cognitive debriefing.

RESULTS

All five short forms were successfully translated and cross-culturally adapted into Nepali while maintaining equivalence to the source.

CONCLUSIONS

The translation and review team, along with a sample from the target population with chronic musculoskeletal pain and the proofreaders considered all five PROMIS short forms relevant and comprehensible. An important next step is to evaluate the measurement properties of these instruments.

Minimal important change (MIC): a conceptual clarification and systematic review of MIC estimates of PROMIS measures

We define the minimal important change (MIC) as a threshold for a minimal within-person change over time above which patients perceive themselves importantly changed. There is a lot of confusion about the concept of MIC, particularly about the concepts of minimal important change and minimal detectable change, which questions the validity of published MIC values. The aims of this study were: (1) to clarify the concept of MIC and how to use it; (2) to provide practical guidance for estimating methodologically sound MIC values; and (3) to improve the applicability of PROMIS by summarizing the available evidence on plausible PROMIS MIC values. We discuss the concept of MIC and how to use it and provide practical guidance for estimating MIC values. In addition, we performed a systematic review in PubMed on MIC values of any PROMIS measure from studies using recommended approaches. A total of 50 studies estimated the MIC of a PROMIS measure, of which 19 studies used less appropriate methods. MIC values of the remaining 31 studies ranged from 0.1 to 12.7 T-score points. We recommend to use the predictive modeling method, possibly supplemented with the vignette-based method, in future MIC studies. We consider a MIC value of 2-6 T-score points for PROMIS measures reasonable to assume at this point. For surgical interventions a higher MIC value might be appropriate. We recommend more high-quality studies estimating MIC values for PROMIS.

Patient-Reported Outcomes Measurement Information System Correlates With Modified Harris Hip Score in Total Hip Arthroplasty

The modified Harris Hip Score (mHHS) is a validated and disease-specific instrument commonly used to assess outcomes in total hip arthroplasty (THA). The Patient-Reported Outcomes Measurement Information System (PROMIS) is a validated, computer adaptive testing (CAT)-based global health assessment tool. The authors' goal was to examine the correlation between PROMIS Pain Interference and Physical Function CATs and the mHHS in patients undergoing primary THA. All THAs were performed by 1 of 2 fellowship-trained dedicated total joint surgeons at 1 academic institution. Patients completed PROMIS and mHHS assessments preoperatively and at 3, 6, 12, and 52 weeks postoperatively. Descriptive statistics and Pearson correlation values were determined. A total of 48 patients were prospectively enrolled in the study. Preoperatively, mean total PROMIS score (Pain Interference and Physical Function) was 74.2 and mHHS was 50.8. Preoperatively, mean total PROMIS score showed a moderate correlation (r=0.56; P<.0001) with total mHHS. Postoperatively, mean total PROMIS score at 3, 6, 12, and 52 weeks was 82.4, 93.4, 100, and 100, respectively (all P<.01 vs baseline), and mHHS was 68.2, 81.1, 85.9, and 88.6, respectively (all P<.01). At 3, 6, 12, and 52 weeks postoperatively, a strong and consistent correlation was observed between the total PROMIS score and mHHS (r=0.74, 0.74, 0.73, and 0.80, respectively; all P<.0001). The PROMIS Pain Interference and Physical Function CATs accurately assessed preoperative pain and dysfunction, as well as clinical improvement following THA. Combined PROMIS Pain Interference and Physical Function is comparable to the mHHS when assessing outcome following THA for osteoarthritis. [Orthopedics. 2021;44(1):e19-e25.].

Clinical outcome assessment in clinical trials of chronic pain treatments

Clinical outcome assessments (COAs) measure outcomes that are meaningful to patients in clinical trials and are critical for determining whether a treatment is effective. The objectives of this study are to (1) describe the different types of COAs and provide an overview of key considerations for evaluating COAs, (2) review COAs and other outcome measures for chronic pain treatments that are recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) or other expert groups, and (3) review advances in understanding pain-related COAs that are relevant to clinical trials. The authors reviewed relevant articles, chapters, and guidance documents from the European Medicines Agency and U.S. Food and Drug Administration. Since the original core set of outcome measures were recommended by IMMPACT 14 years ago, several new advancements and publications relevant to the measurement or interpretation of COAs for chronic pain trials have emerged, presenting new research opportunities. Despite progress in the quality of measurement of several outcome domains for clinical trials of chronic pain, there remain some measurement challenges that require further methodological investigation.

Responsiveness to change over time and test-retest reliability of the PROMIS and Neuro-QoL mental health measures in persons with Huntington disease (HD)

BACKGROUND

The majority of persons with Huntington disease (HD) experience mental health symptoms. Patient-reported outcome (PRO) measures are capable of capturing unobservable behaviors and feelings relating to mental health. The current study aimed to test the reliability and responsiveness to self-reported and clinician-rated change over time of Neuro-QoL and PROMIS mental health PROs over the course of a 24-month period.

METHODS

At baseline, 12-months, and 24-months, 362 participants with premanifest or manifest HD completed the Neuro-QoL Depression computer adaptive test (CAT), PROMIS Depression short form (SF), Neuro-QoL Anxiety CAT, PROMIS Anxiety SF, PROMIS Anger CAT and SF, Neuro-QoL Emotional/Behavioral Dyscontrol CAT and SF, Neuro-QoL Positive Affect and Well-Being CAT and SF, and Neuro-QoL Stigma CAT and SF. Participants completed several clinician-administered measures at each time point, as well as several global ratings of change at 12- and 24-months. Reliability (test-retest reliability and measurement error) and responsiveness (using standardized response means and general linear models) were assessed.

RESULTS

Test-retest reliability and measurement error were excellent for all PROs (all ICC ≥ .90 for test-retest reliability and all SEM percentages ≤ 6.82%). In addition, 12- and 24-month responsiveness were generally supported for the Neuro-QoL and PROMIS mental health PROs; findings relative to clinician-rated anchors of change (e.g., SRMs for the group with declines ranged from .38 to .91 for 24-month change and .09 to .45, with the majority above .25 for 12-month change) were generally more robust than those relative to self-reported anchors of change (e.g., SRMs for the group with declines ranged from .02 to .75, with the majority above .39 for 24-month change and .09 to .45, with the majority above .16 for 12-month change).

CONCLUSIONS

The Neuro-QoL and PROMIS mental health PROs demonstrated strong psychometric reliability, as well as responsiveness to self-reported and clinician-rated change over time in people with HD.

Responsiveness of quality of life measures in children with peripheral vascular malformations: The OVAMA project

Background

The OVAMA (Outcome Measures for VAscular MAlformations) project determined quality of life (QoL) as a core outcome domain for evaluating treatment effect in vascular malformations. To correctly evaluate treatment effect on QoL, patient-reported outcome measures (PROMs) are needed that are responsive to changes. In children with vascular malformations, we explored if two widely used PROMs were responsive to changes: the Pediatric Quality of Life Inventory (PedsQL) and the Children's Dermatology Life Quality Index (CDLQI).

Methods

In an international multicenter prospective study, conservatively and invasively treated children completed the PedsQL and CDLQI at baseline and after follow-up of 6-8 weeks. At follow-up, change in health was assessed by a global rating of change (GRC) scale. Responsiveness was assessed by testing hypotheses on expected correlation strength between change scores of the PROMs and the GRC scale, and by calculating the area under the receiver operating characteristics curve (AUC). The PROMs were considered responsive if ≥75% of the hypotheses were confirmed or if the AUC was ≥0.7.

Results

Twenty-nine children were recruited in three centers in the Netherlands and United States, of which 25 completed all baseline and follow-up measurements. For both the PedsQL and CDLQI, less than 75% of the hypotheses were confirmed and the AUC was <0.7.

Discussion

The results suggest that these PROMs are not sufficiently responsive for evaluating treatment effect in peripheral vascular malformations. Our study emphasizes the need for assessing responsiveness before using a PROM in evaluating treatment effect.

Rate of Surgery and Baseline Characteristics Associated With Surgery Progression in Young Athletes With Prearthritic Hip Disorders

Background:

Prearthritic hip disorders (PAHD), such as femoroacetabular impingement (FAI), acetabular dysplasia, and acetabular labral tears, are a common cause of pain and dysfunction in adolescent and young adult athletes, and optimal patient-specific treatment has not been defined. Operative management is often recommended, but conservative management may be a reasonable approach for some athletes.

Purpose:

To identify (1) the relative rate of progression to surgery in self-reported competitive athletes versus nonathletes with PAHD and (2) baseline demographic, pain, and functional differences between athletes who proceeded versus those who did not proceed to surgery within 1 year of evaluation.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

An electronic medical record review was performed of middle school, high school, and college patients who were evaluated for PAHD at a single tertiary-care academic medical center between June 22, 2015, and May 1, 2018. Extracted variables included patients’ self-reported athlete status, decision to choose surgery within 1 year of evaluation, and baseline self-reported pain and functional scores on Patient-Reported Outcomes Measurement Information System (PROMIS) domains, the Hip disability and Osteoarthritis Outcome Score (HOOS), and the modified Harris Hip Score.

Results:

Of 260 eligible patients (289 hips), 203 patients (78%; 227 hips) were athletes. Athletes were no more likely to choose surgery than nonathletes (130/227 hips [57%] vs 36/62 hips [58%]; relative risk [RR], 0.99 [95% CI, 0.78-1.25]). Among athletes, those who proceeded to surgery over conservative care were more likely to be female (81% vs 69%; RR, 1.34 [95% CI, 0.98-1.83]) and had more known imaging abnormalities (FAI: 82% vs 69%, RR, 1.47 [95% CI, 1.09-1.99]; dysplasia: 48% vs 27%, RR, 1.44 [95% CI, 1.16-1.79]; mixed deformity: 30% vs 10%, RR, 2.91 [95% CI, 1.53-5.54]; known labral tear: 84% vs 40%, RR, 2.79 [95% CI, 2.06-3.76]). Athletes who chose surgery also reported worse baseline hip-specific symptoms on all HOOS subscales (mean difference, 10.8-17.7; P < .01 for all).

Conclusion:

Similar to nonathletes, just over half of athletes with PAHD chose surgical management within 1 year of evaluation. Many competitive athletes with PAHD continued with conservative management and deferred surgery, but more structural hip pathology and worse hip-related baseline physical impairment were associated with the choice to pursue surgery.

Anxiety impacts rheumatoid arthritis symptoms and health-related quality of life even at low levels

OBJECTIVES

We explored the burden of symptoms of anxiety and depression on health-related quality of life (HRQL) in patients with rheumatoid arthritis (RA).

METHODS

Adults with RA participating in an observational cohort completed PROMIS tests of depression, anxiety, fatigue, physical function (PF), pain interference (PI), sleep disturbance, and participation in social roles and activities at the baseline visit. Clinical measures of disease status were also obtained. We used ANOVA and partial correlation adjusting for the swollen joint count (SJC) to examine associations of anxiety and depression with other aspects of HRQL. Mild and moderate-severe anxiety were defined as T-scores ≥55.4 and ≥ 62.3 and mild and moderate-severe depression was defined as ≥52.5 and ≥58.6 based on previous validated clinical thresholds. Multivariable linear regression (MVR) was used to identify predictors of emotional distress with a subset analysis of those in remission/low disease activity.

RESULTS

Of 196 RA participants, 18% had mild anxiety, 9% had moderate-severe anxiety, 18% had mild depression, and 14% had moderate-severe depression symptoms. Anxiety and depression scores were associated with significantly worse mean scores across HRQL domains (p <0.05). In MVR, depression (β=0.75, p<0.001), PF (β=0.14, p=0.024) and fatigue (β=0.15, p=0.015) predicted higher anxiety levels, whereas only anxiety predicted higher depression levels (β=0.70, p=<0.001). In subset analysis, PF no longer predicted higher anxiety levels.

CONCLUSIONS

Emotional distress is common in RA, even when disease is well controlled, with considerable impacts on other aspects of HRQL even at mild levels.

•The effect of resistance exercise with BRF is not more effective that resistance exercise in in patients with knee pain. •Our study was unable to demonstrate the clinical benefits of resistance exercise with BRF in subjects with knee pain. •Further studies are needed to support the clinical effect of BRF in pain intensity and knee function in these patients.

Effectiveness and safety of massage for knee osteoarthritis: A protocol for systematic review and meta-analysis

BACKGROUND

Knee osteoarthritis (KOA), a concerning public health problem, seriously threatens well being of human beings. At present, studies have shown that massage therapy is effective in relieving related symptoms of KOA. However, the evidence of massage for KOA has not been systematically evaluated. Therefore, the study is conducted to systematically assess the reliability of patients with KOA treated by massage.

METHODS

We will retrieve the relevant literature of massage for KOA from PubMed, Cochrane Library, EMBASE, Web of Science, Wanfang, Chongqing VIP, CNKI, and Chinese Biomedical Literature Database from the establishment of the databases to August 1, 2020. Two researchers will independently perform the screening of literature and extract the basic information of the data. In addition, RevMan V.5.3 software will be used for data analysis.

RESULTS

The study will comprehensively assess the effect of massage for KOA.

CONCLUSION

The study will provide comprehensive evidence for evaluating whether massage therapy is useful in treating patients with KOA.

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.

The impact of functional medicine on patient-reported outcomes in inflammatory arthritis: A retrospective study

BACKGROUND

Despite treatment advances for inflammatory arthritis, a significant amount of patients fail to achieve remission. Other modifiable factors such as diet, physical activity and environmental exposures may be an important area of focus to help patients achieve disease remission and greater overall health. Functional medicine focuses on these lifestyle factors and may be an important adjunctive therapy. In this study, we examined the impact of functional medicine on patient-reported outcomes in patients with inflammatory arthritis.

MATERIALS AND METHODS

In this 12-week, retrospective study, patients with confirmed diagnoses of rheumatoid arthritis (RA) or psoriatic arthritis (PsA) were treated according to guidelines from the American College of Rheumatology for RA or PSA respectively. Those in the functional medicine group underwent a functional medicine program adjunctive to the standard of care. Patient reported outcomes, such as PROMIS (Patient Reported Outcomes Measurement Information System) global physical health, mental health and pain scores were collected at baseline and 12 weeks. Multivariable statistical modeling was used to identify the impact of functional medicine on patient-reported outcomes.

RESULTS

318 patients were screened and 54 patients (mean age 52.9±11.3 years, females 74(67.9%)), were included. Baseline characteristics were similar in both patient groups with the exception of PROMIS global physical health and pain (PROMIS global physical health score 43·2 ± 6·6 and 39·7 ± 8·7 and pain scores of 3·5 ± 1·9 and 5·2 ± 2·7 in the functional medicine group vs. standard of care group respectively). Using multivariable model to account for these differences, patients in the functional medicine group had a statistically significant reduction in pain (0.92, p-value = 0.007) and change in PROMIS physical health score (2·84, p-value = 0.001) as compared to the standard of care. Changes in PROMIS global mental health scores were also significant and were dependent on age and were greatest in those older than 55.

LIMITATIONS

Retrospective design, baseline difference in patient reported outcomes.

CONCLUSIONS

Functional medicine may have an important role as adjunctive therapy to improve patients' pain, physical and mental health in those who do not see improvement with conventional therapy alone.
