Relevance of learning health systems to physiatrists and its synergy with implementation science: A commentary.

As health care attempts to bridge the gap between evidence and practice, the concept of the learning health system (LHS) is becoming increasingly relevant. LHS integrates evidence with health systems data, driving health care quality and outcomes through updates in policy, practice, and care delivery. In addition, LHS research is becoming critically important as there are several initiatives underway to increase research capacity, expertise, and implementation, including attempts to stimulate increasing numbers of LHS researchers. Physical Medicine & Rehabilitation (PM&R) physicians (physiatrists), nurses, therapists (physical therapists, occupational therapists, speech therapists, clinical psychologists), and scientists are affiliated with LHSs. As LHS research expands in health care systems, better awareness and understanding of LHSs and LHS research competencies are key for rehabilitation professionals including physiatrists. To address this need, the Agency of Healthcare Research and Quality (AHRQ) identified 33 core competencies, grouped into eight domains, for training LHS researchers. The domains are: (1) Systems Science; (2) Research Questions and Standards of Scientific Evidence; (3) Research Methods; (4) Informatics; (5) Ethics of Research and Implementation in Health Systems; (6) Improvement and Implementation Science; (7) Engagement, Leadership, and Research Management; and the recently added (8) Health and Healthcare Equity and Justice. The purpose of this commentary is to define LHS and its relevance to physiatrists, present the role of implementation science (IS) in LHSs and application of IS principles to design LHSs, illustrate current LHS research in rehabilitation, and discuss potential solutions to improve awareness and to stimulate interest in LHS research and IS among physiatrists in LHSs.

Falls in people with mobility limitations: a cross-sectional analysis of a US registry of assistive device users.

Purpose of the Article: To (1) summarise the personal and clinical characteristics of persons with disabilities (PwDs) in the US who were evaluated for mobility assistive equipment (MAE) in the functional mobility assessment and uniform dataset (FMA/UDS) and (2) stratify subpopulations of PwD who reported falling versus those who do not report a fall.Materials and Methods: This study was a retrospective, descriptive cohort analysis of adults with disabilities using the FMA/UDS. Data are collected during a user's initial evaluation for a new mobility device. The sample is intentionally general to be inclusive of all mobility device users. The primary variable of interest was a patient-reported fall within the 3 months leading up to their evaluation for a new mobility device. Subpopulation characteristics were stratified by this binary fall variable.Results and Conclusions: This study provides descriptions of PwDs being evaluated for a new mobility device. There were 11,084 PwDs with 31 different primary diagnoses. During their new mobility device evaluation, 52.2% of PwDs reported at least one fall in the last 3 months. For those who reported a fall, 46.6% of PwDs were using a walking aid or no device at all before the new mobility device evaluation. Additionally, persons with progressively acquired disabilities (i.e., Parkinson's disease, osteoarthritis and cardiopulmonary disease) reported higher rates of falls than those with congenital disabilities (i.e., cerebral palsy and spina bifida). These findings will influence future studies comparing different types of devices and their influence on falls and user satisfaction.Implications for rehabilitation52.2% of persons with disabilities (PwDs) seeking a new wheelchair evaluation reported at least one fall in the last 3 months.Persons with progressively acquired disabilities (i.e., Parkinson's disease, osteoarthritis and cardiopulmonary disease) reported higher rates of falls than those with congenital disabilities (i.e., cerebral palsy and spina bifida).Earlier interventions for fall prevention including professional wheelchair evaluations may be warranted, but further research is necessary to explore long-term effectiveness.

Development of an exercise therapy referral clinical support tool for patients with osteoporosis at risk for falls.

BACKGROUND: The purpose of this study was to develop a clinical support tool for osteoporosis clinic providers to support risk assessment and referrals for evidence-based exercise therapy programs. METHODS: A sequential Delphi method was used with a multidisciplinary group of national falls experts, to provide consensus on referral to exercise therapy for patients at risk for falls. The Delphi study included a primary research team, expert panel, and clinical partners to answer the questions: (1) "What patient characteristics are needed to develop a clinical support tool?"; (2) "What are the recommended exercise referrals for patients with osteoporosis at risk for falls?" The consensus process consisted of two rounds with 8 weeks between meetings. Two qualitative researchers analyzed the data using a modified version of a matrix analysis approach. RESULTS: The following were the most important variables to include when determining exercise therapy referrals for patients with osteoporosis: Patient history and demographics, falls history over the last year, current physical function and balance, caregiver and transportation status, socioeconomic and insurance status, and patient preference. Potential exercise therapy referrals included one-on-one physical therapy, group physical therapy, home health, community-based exercise programs, and not acceptable for exercise therapy. CONCLUSIONS: Patient characteristics including patient history, physical function and balance performance, socioeconomic and insurance status, and patient preference for exercise therapy are important to inform both the medical provider and patient with osteoporosis to choose the most appropriate exercise therapy referral. Adoption of the algorithmic suggestions may have a significant impact on uptake and adherence to exercise therapy, ultimately improving patient physical function and reducing falls risk.

A Cluster Analysis of Initial Primary Care Orders for Patients with Acute Low Back Pain.

PURPOSE: Primary care physicians (PCPs) often face a complex intersection of patient expectations, evidence, and policy that influences their care recommendations for acute low back pain (aLBP). The purpose of this study was to elucidate patterns of PCP orders for patients with aLBP, identify the most common patterns, and describe patient clinical and demographic characteristics associated with patterns of aLBP care. METHODS: This prospective cohort study included 9574 aLBP patients presenting to 1 of 77 primary care practices in 4 geographic locations in the United States. We performed a cluster analysis of PCP orders extracted from electronic health records within the first 21 days of an initial visit for aLBP. RESULTS: 1401 (15%) patients did not receive a PCP order related to back pain within the first 21 days of their initial visit. These patients predominantly had aLBP without leg pain, less back-related disability, and were at low-risk for persistent disability. Of the remaining 8146 patients, we found 4 distinct order patterns: combined nonpharmacologic and first-line medication (44%); second-line medication (39%); imaging (10%); and specialty referral (7%). Among all patients, 29% received solely 1 order from their PCP. PCPs more often combined different guideline concordant and discordant orders. Patients with higher self-reported disability and psychological distress were more likely to receive guideline discordant care. CONCLUSION: Guideline discordant orders such as steroids and NSAIDS are often combined with guideline recommended orders such as physical therapy. Further defining patient, clinician, and health care setting characteristics associated with discordant care would inform targeted efforts for deimplementation initiatives.

Feasibility of Implementing Patient-Reported and Physical Performance Measures to Identify and Manage Fall Risk in Older Adults Within a Secondary Fracture Clinic.

The purpose of this study was to assess the feasibility of implementing both electronic and in-person assessments to assess falls risk in an older adult secondary fracture clinic. Electronic data capture feasibility was defined as the proportion of patients that completed the electronic questionnaires prior to their clinic visit. In-clinic feasibility was defined in two ways: (1) the proportion of patients that consented to participate at their clinic visit; (2) time to complete testing. Patients were contacted electronically through their health system portal for electronic consent. Patients were invited to complete consent, the STopping Elderly Accidents, Deaths, and Injuries (STEADI) falls risk assessment tool, and the visual analog scale (VAS) for pain. The Short Physical Performance Battery (SPPB) was performed at the clinic visit. A total of 310 patients were contacted electronically. No patients (0%) provided consent through their health portal. Of the 310 patients, 200 (65%) consented in person (Ineligible: 67 [21%]; Declined: 43 [14%]), resulting in an 82% response rate. In-person data collection took a median of 38.48 (Range: 12.34-54.30) minutes to complete. It was not feasible to contact and collect older adult patient data electronically prior to clinic; but, was feasible to obtain these patient-reported outcomes and physical performance data in person.

Determining Unmet Needs Among Workers' Compensation Stakeholders to Prevent Work Disability in the State of Vermont.

PURPOSE: Vermont has high rates of young people receiving federal disability benefits leading to substantial gaps in the workforce. The purpose of this project was to determine the unmet needs of interested parties in the workers' compensation (WC) process. METHODS: A type of focus group, experience groups, was used to elicit key parties' experiences in the WC system. Facilitators used open-ended prompts to encourage discussion among participants about their experience with the WC system. Data were analyzed using thematic coding procedures to identify common motifs. RESULTS: Common themes emerged including challenges in navigating the WC system, lack of communication among stakeholders, and providing and receiving appropriate health care to facilitate RTW. CONCLUSIONS: Understanding unmet needs of interested parties in the WC process allows for the creation of targeted, high-value, early intervention strategies to reduce long-term work disability.

Proximal humerus fracture management and outcomes are distinctly different for individuals 60 years of age or younger: a systematic review.

Background: Proximal humerus fractures (PHFs) occur most commonly in an elderly and osteoporotic population, but a considerable proportion of these injuries occur in relatively younger individuals. Differences in treatment principles and outcomes in this younger population remain poorly understood. The purpose of this review was to characterize the treatment algorithms and outcomes for patients less than or equal to 60 years of age with PHFs. Methods: A comprehensive search of the Medline, Pubmed, Embase, and Cochrane databases for articles published between January 2005 and December 2020 was performed in January 2021. Levels of evidence I-IV analyzing outcomes (patient reported outcomes and/or complications) following PHFs in adult patients less than or equal to 60 years of age were included. The search was carried out in accordance with the preferred reported items for systematic reviews and meta-analyses guidelines. The risk of bias 2 tool and methodological index for nonrandomized studies score were utilized to evaluate included studies. Results: Fourteen studies met the inclusion criteria (open reduction internal fixation: 5, intramedullary nail: 4, hemiarthroplasty: 2, nonoperative: 1, and reverse total shoulder arthroplasty (RTSA): 1). Seven studies reported differences in outcomes between younger and older patient populations, with three studies noting separate management algorithms for those 60 years of age or younger. There were no studies comparing different treatments modalities in those less than 60 years of age, and the lone study on RTSA did not include patient-reported outcomes. Conclusion: Treatment algorithms and outcomes following PHFs in patients less than or equal to 60 years of age are distinctly different from that of a more elderly population. However, evidence-based treatment recommendations for this younger population are limited by the lack of studies comparing treatment modalities and the absence of patient-reported outcomes for individuals undergoing RTSA.

Medicare Advantage Patterns of Poststroke Discharge to an Inpatient Rehabilitation or Skilled Nursing Facility: A Consideration of Demographic, Functional, and Payer Factors.

OBJECTIVE: The purpose of this study was to determine the factors influencing the discharge to an inpatient rehabilitation facility (IRF) or a skilled nursing facility (SNF) of people poststroke with Medicare Advantage plans. METHODS: A retrospective cohort study was conducted with data from naviHealth, a company that manages postacute care discharge placement on behalf of Medicare Advantage organizations. The dependent variable was discharge destination (IRF or SNF). Variables included age, sex, prior living setting, functional status (Activity Measure for Post-Acute Care [AM-PAC]), acute hospital length of stay, comorbidities, and payers (health plans). Analysis estimated relative risk (RR) of discharge to SNF, while controlling for regional variation. RESULTS: Individuals discharged to an SNF were older (RR = 1.17), women (RR = 1.05), lived at home alone or in assisted living (RR = 1.13 and 1.39, respectively), had comorbidities impacting their function "some" or "severely" (RR = 1.43 and 1.81, respectively), and had a length of stay greater than 5 days (RR = 1.16). Individuals with better AM-PAC Basic Mobility (RR = 0.95) went to an IRF, and individuals with better Daily Activity (RR = 1.01) scores went to an SNF. There was a substantial, significant variation in discharge of individuals to SNF by payer group (RR range = 1.12-1.92). CONCLUSIONS: The results of this study show that individuals poststroke are more likely to be discharged to an SNF than to an IRF. This study did not find a different discharge decision-making picture for those with Medicare Advantage plans than previously described for other insurance programs. IMPACT: Medicare Advantage payers have varied patterns in discharge placement to an IRF or SNF for patients poststroke.

Learning Health Systems Research Competencies: A Survey of the Rehabilitation Research Community.

OBJECTIVE: The Learning Health Systems Rehabilitation Research Network (LeaRRn), an NIH-funded rehabilitation research resource center, aims to advance the research capacity of learning health systems (LHSs) within the rehabilitation community. A needs assessment survey was administered to inform development of educational resources. METHODS: The online survey included 55 items addressing interest in and knowledge of 33 LHS research core competencies in 7 domains and additional items on respondent characteristics. Recruitment targeting rehabilitation researchers and health system collaborators was conducted by LeaRRn, LeaRRn health system partners, rehabilitation professional organizations, and research university program directors using email, listservs, and social media announcements. RESULTS: Of the 650 people who initiated the survey, 410 respondents constituted the study sample. Respondents indicated interest in LHS research and responded to at least 1 competency item and/or demographic question. Two-thirds of the study sample had doctoral research degrees, and one-third reported research as their profession. The most common clinical disciplines were physical therapy (38%), communication sciences and disorders (22%), and occupational therapy (10%). Across all 55 competency items, 95% of respondents expressed "a lot" or "some" interest in learning more, but only 19% reported "a lot" of knowledge. Respondents reported "a lot" of interest in a range of topics, including selecting outcome measures that are meaningful to patients (78%) and implementing research evidence in health systems (75%). "None" or "some" knowledge was reported most often in Systems Science areas such as understanding the interrelationships between financing, organization, delivery, and rehabilitation outcomes (93%) and assessing the extent to which research activities will improve the equity of health systems (93%). CONCLUSION: Results from this large survey of the rehabilitation research community indicate strong interest in LHS research competencies and opportunities to advance skills and training. IMPACT: Competencies where respondents indicated high interest and limited knowledge can inform development of LHS educational content that is most needed.

Informatics Research on Mental Health Functioning: Decision Support for the Social Security Administration Disability Program.

The disability determination process of the Social Security Administration's (SSA's) disability program requires assessing work-related functioning for individual claimants alleging disability due to mental impairment. This task is particularly challenging because the determination process involves the review of a large file of information, including objective medical evidence and self-reports from claimants, families, and former employers. To improve this decision-making process, SSA entered an interagency agreement with the Rehabilitation Medicine Department, Epidemiology and Biostatistics Section, in the Clinical Center of the National Institutes of Health, intending to use data science and informatics to develop decision support tools. This collaborative effort over the past decade has led to the development of the Work Disability-Functional Assessment Battery and has initiated an approach to applying natural language processing to the review of claimants' files for information on mental health functioning. This informatics research collaboration holds promise for improving the process of disability determination for individuals with mental impairments who make claims at the SSA.

Linking job duties, functioning, and employment status using the Work-Disability Functional Assessment Battery (WD-FAB): An expert coding and quantitative analysis.

BACKGROUND: An understanding of the link between specific occupational demands and individual worker functioning is limited, although such information could permit an assessment of the fit between the two in a manner that would inform national and state disability programs such as vocational rehabilitation and Social Security disability programs. OBJECTIVE: Our goal was to examine the utility of assessing physical and mental functioning relative to self-reported job duties to identify the domains of worker functioning most likely to create barriers to fulfilling an occupation's specific requirements. METHODS: Through primary survey data collection, 1770 participants completed the Work-Disability Functional Assessment Battery (WD-FAB) instrument after reporting details on their occupations (or most recent occupation if not working). Expert coders evaluated the level of function expected to successfully carry out each self-reported job duty with respect to six scales of physical and mental function. Quantitative analysis is used to examine the relationship between functioning and job duties. RESULTS: Those not working due to disability were more likely to fall short of the threshold of the physical and mental functioning requirements of their last job's three main job duties compared to those currently employed. Mental function scales were most likely to be the area experiencing a shortfall. CONCLUSIONS: Functional difficulties impede the ability to continue working in particular jobs that require that ability. This points to a need for specific accommodations to be implemented to bridge the gap between job requirements and functional capacity so that workers may remain engaged in their current work.

Trends in Level of Evidence of Systematic Reviews in Sports Medicine, 2010-2020 : A Systematic Review and Meta-analysis.

Background: Popularization of systematic reviews has been met with controversy because of concerns that the primary literature for certain topics may not be suited for systematic review and meta-analysis. Purpose: To assess the rate of publication of systematic reviews based on their level of evidence (LOE) in influential orthopaedic sports medicine journals and commonly studied topics in sports medicine. Study Design: Systematic review. Methods: An electronic search was performed using the PubMed database of studies published from January 2010 to December 2020. The advanced search function was used to identify systematic reviews from the Journal of Shoulder and Elbow Surgery (JSES), American Journal of Sports Medicine (AJSM), Arthroscopy, British Journal of Sports Medicine (BJSM), Journal of Bone and Joint Surgery-American Volume (JBJS), and Sports Medicine (SM Auckland), as well as reviews of the most common areas of sports medicine research, including rotator cuff repair (RCR), shoulder instability (SI), anterior cruciate ligament reconstruction (ACLR), and meniscal repair. The LOE was assigned to each included study according to the Oxford Centre for Evidence-Based Medicine. Studies were grouped as LOE 1-2, LOE 3-5, and nonclinical systematic reviews. A negative binomial regression was used to determine the changes in publication rate over time. Results: A total of 2162 systematic reviews were included in this study. From 2010 to 2020, the rate of publication of LOE 3-5 systematic reviews increased significantly among most of the surveyed journals (AJSM, P < .0001; Arthroscopy, P = .01; BJSM, P < .0001; JSES, P < .0001; SM Auckland, P < .0001), with the exception of JBJS (P = .57). The rate of publication of LOE 1-2 systematic reviews increased in AJSM (P < .0001), Arthroscopy (P = .02), BJSM (P < .0001), and SM Auckland (P < .0001); however, no significant changes were seen in JBJS (P = .08) or JSES (P = .15). The publication rate of LOE 3-5 systematic reviews increased for all sports medicine topics surveyed (meniscal repair, P < .0001; RCR, P < .0001; SI, P < .0001; ACLR, P < .0001). However, the publication rate of LOE 1-2 studies only increased for RCR (P = .0003) and ACLR (P < .0001). Conclusion: The rate of publication of LOE 3-5 systematic reviews exponentially increased in orthopaedic sports medicine journals over the past decade, outpacing the publication rate of LOE 1-2 systematic reviews.

Development of a rehabilitation researcher survey of knowledge and interest in learning health systems research.

Introduction: LeaRRn, an NIH-funded rehabilitation resource center, is dedicated to developing learning health systems (LHS) research competencies within the rehabilitation community. To appropriately target resources and training opportunities for rehabilitation researchers, we developed and pilot tested a survey based on AHRQ LHS research core competencies to assess the training needs of rehabilitation researchers interested in LHS research. Methods: Survey items were developed by the investigative team and iteratively refined with the assistance of an expert panel using two rounds of content validation. Survey items addressed knowledge of, ability to apply, and interest in LHS research competencies. The survey was pre-pilot tested with six rehabilitation professionals, refined again, and then pilot tested. Time to complete the survey was measured. Spearman correlations examined relationships between knowledge and ability. Results: A 78-item survey was pilot tested. Forty-five individuals completed the pilot survey in full (71% female, 84% white, and 93% non-Hispanic). Due to concerns about response burden (mean 15 minutes to complete) and strong correlation between "knowledge" and "ability" ratings (all rho >0.57), "ability" was dropped, resulting in a 55-item survey assessing "knowledge" and "interest" in LHS research competencies. Conclusions: We developed a survey of knowledge and interest in LHS research competencies for rehabilitation researchers. The resulting survey may be used to assess training needs and guide LHS research content development by educators, programs directors, and other initiatives within the rehabilitation research community.

Information Extraction Framework for Disability Determination Using a Mental Functioning Use-Case.

Natural language processing (NLP) in health care enables transformation of complex narrative information into high value products such as clinical decision support and adverse event monitoring in real time via the electronic health record (EHR). However, information technologies for mental health have consistently lagged because of the complexity of measuring and modeling mental health and illness. The use of NLP to support management of mental health conditions is a viable topic that has not been explored in depth. This paper provides a framework for the advanced application of NLP methods to identify, extract, and organize information on mental health and functioning to inform the decision-making process applied to assessing mental health. We present a use-case related to work disability, guided by the disability determination process of the US Social Security Administration (SSA). From this perspective, the following questions must be addressed about each problem that leads to a disability benefits claim: When did the problem occur and how long has it existed? How severe is it? Does it affect the person's ability to work? and What is the source of the evidence about the problem? Our framework includes 4 dimensions of medical information that are central to assessing disability-temporal sequence and duration, severity, context, and information source. We describe key aspects of each dimension and promising approaches for application in mental functioning. For example, to address temporality, a complete functional timeline must be created with all relevant aspects of functioning such as intermittence, persistence, and recurrence. Severity of mental health symptoms can be successfully identified and extracted on a 4-level ordinal scale from absent to severe. Some NLP work has been reported on the extraction of context for specific cases of wheelchair use in clinical settings. We discuss the links between the task of information source assessment and work on source attribution, coreference resolution, event extraction, and rule-based methods. Gaps were identified in NLP applications that directly applied to the framework and in existing relevant annotated data sets. We highlighted NLP methods with the potential for advanced application in the field of mental functioning. Findings of this work will inform the development of instruments for supporting SSA adjudicators in their disability determination process. The 4 dimensions of medical information may have relevance for a broad array of individuals and organizations responsible for assessing mental health function and ability. Further, our framework with 4 specific dimensions presents significant opportunity for the application of NLP in the realm of mental health and functioning beyond the SSA setting, and it may support the development of robust tools and methods for decision-making related to clinical care, program implementation, and other outcomes.

A multi-center trial of exercise and testosterone therapy in women after hip fracture: Design, methods and impact of the COVID-19 pandemic.

BACKGROUND: Up to 75% of hip fracture patients never recover to their pre-fracture functional status. Supervised exercise that includes strength training can improve functional recovery after hip fracture. The role of testosterone replacement for augmenting the effects of exercise in older women after hip fracture is unknown. METHODS: The Starting Testosterone and Exercise after Hip Injury (STEP-HI) Study is a 6-month Phase 3 multicenter randomized placebo-controlled trial designed to compare supervised exercise (EX) plus 1% testosterone topical gel, with EX plus placebo gel, and with enhanced usual care (EUC). Female hip fracture patients age ≥ 65 years are being recruited from clinical centers across the United States. Participants are community dwelling and enrolled within 24 weeks after surgical repair of the fracture. The EX intervention is a center-based program of progressive resistance training. The EUC group receives a home exercise program and health education. Participants receive dietary counseling, calcium and vitamin D. The primary outcome is the Six Minute Walk Distance. Secondary outcomes include physical performance measures, self-reported function and quality of life, and dual energy x-ray absorptiometry measures of body composition and bone mineral density. RESULTS: Enrollment, interventions, and follow-up are ongoing. We describe the impact of the coronavirus disease 2019 pandemic on the trial, including modifications made to allow continuation of the interventions and outcome data collection using remote video and audio technology. CONCLUSIONS: Results from the STEP-HI study are expected to have important clinical and public health implications for management of the growing population of hip fracture patients.

Physical Therapy Management of Older Adults With Hip Fracture.

Hip fracture is a leading cause of profound morbidity in individuals aged 65 years and older, ranking in the top 10 causes of loss of disability-adjusted life-years for older adults. Worldwide, the number of people with hip fracture is expected to rise significantly due to the aging population and other factors. Physical therapist management is recommended within medical, surgical, and multidisciplinary clinical practice guideline (CPGs) and is considered to be the standard of care in rehabilitation for people with hip fracture. The goal of this CPG was to review the evidence relevant to physical therapist management and to provide evidence-based recommendations for physical therapy diagnosis, prognosis, intervention, and assessment of outcome in adults with hip fracture.

The Development of a Crosswalk for Functional Measures in Postacute Medicare Claims.

OBJECTIVE: Although Medicare assessment files will include Standardized Patient Assessment Data Elements from 2016 forward, lack of uniformity of functional data prior to 2016 impedes longitudinal research. The purpose of this study was to create crosswalks for postacute care assessment measures and the basic mobility and daily activities scales of the Activity Measure for Post-Acute Care (AM-PAC) and to test their accuracy and validity in development and validation datasets. METHODS: This cross-sectional study is a secondary analysis of AM-PAC, the Inpatient Rehabilitation Facility Patient Assessment Instrument, the Minimum Data Set, and the Outcome and Assessment Information Set data from 300 adults receiving rehabilitation recruited from 6 health care networks in 1 metropolitan area. Rasch analysis was used to co-calibrate items from the 3 measures onto the AM-PAC metric and to create look-up tables to create estimated AM-PAC (eAM-PAC) scores. Mean scores and correlation and agreement between actual and estimated scores were examined in the development dataset. Scores were estimated in a cohort of Medicare beneficiaries with hip, humerus and radius fractures. Correlations between eAM-PAC and Functional Independence Measure motor scores were examined. Differences in mean eAM-PAC scores were evaluated across groups of known differences (age, fracture type, dementia). RESULTS: Strong correlations were found between actual and eAM-PAC scores in the development dataset. Moderate to strong correlations were found between the eAM-PAC basic mobility and Functional Independence Measure motor scores in the validation dataset. Differences in basic mobility scores across known groups were statistically significant and appeared to be clinically important. Differences between mean daily activities scores were statistically significant but appeared not to be clinically important. CONCLUSION: Although further testing is warranted, the basic mobility crosswalk appears to provide valid scores for aggregate analysis of Medicare postacute care data. IMPACT: This study reports on a method to take data from different Medicare administrative data sources and estimate scores on 1 scale. This approach was applied separately for data related to basic mobility and to daily activities. This may allow researchers to overcome challenges with using Medicare administrative data from different sources.

Association of Initial Provider Type on Opioid Fills for Individuals With Neck Pain.

OBJECTIVE: To determine whether the initial care provider for neck pain was associated with opioid use for individuals with neck pain. DESIGN: Retrospective cohort study. SETTING: Marketscan research databases. PARTICIPANTS: Patients (N=427,966) with new-onset neck pain from 2010-2014. MAIN OUTCOME MEASURES: Opioid use was defined using retail pharmacy fills. We performed logistic regression analysis to assess the association between initial provider and opioid use. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using bootstrapping logistic models. We performed propensity score matching as a robustness check on our findings. RESULTS: Compared to patients with neck pain who saw a primary health care provider, patients with neck pain who initially saw a conservative therapist were 72%-91% less likely to fill an opioid prescription in the first 30 days, and between 41%-87% less likely to continue filling prescriptions for 1 year. People with neck pain who initially saw emergency medicine physicians had the highest odds of opioid use during the first 30 days (OR, 3.58; 95% CI, 3.47-3.69; P<.001). CONCLUSIONS: A patient's initial clinical contact for neck pain may be an important opportunity to influence subsequent opioid use. Understanding more about the roles that conservative therapists play in the treatment of neck pain may be key in unlocking new ways to lessen the burden of opioid use in the United States.
