Variation in Time-to-Gender-Affirming Hormone Therapy in US Active Duty Service Members.

BACKGROUND: Beginning in July 2016, transgender service members in the US military were allowed to receive gender-affirming medical care, if so desired. OBJECTIVE: This study aimed to evaluate variation in time-to-hormone therapy initiation in active duty Service members after the receipt of a diagnosis indicative of gender dysphoria in the Military Health System. RESEARCH DESIGN: This retrospective cohort study included data from those enrolled in TRICARE Prime between July 2016 and December 2021 and extracted from the Military Health System Data Repository. PARTICIPANTS: A population-based sample of US Service members who had an encounter with a relevant International Classification of Diseases 9/10 diagnosis code. MEASURES: Time-to-gender-affirming hormone initiation after diagnosis receipt. RESULTS: A total of 2439 Service members were included (M age 24 y; 62% white, 16% Black; 12% Latine; 65% Junior Enlisted; 37% Army, 29% Navy, 25% Air Force, 7% Marine Corps; 46% first recorded administrative assigned gender marker female). Overall, 41% and 52% initiated gender-affirming hormone therapy within 1 and 3 years of diagnosis, respectively. In the generalized additive model, time-to-gender-affirming hormone initiation was longer for Service members with a first administrative assigned gender marker of male relative to female ( P <0.001), and Asian and Pacific Islander ( P =0.02) and Black ( P =0.047) relative to white Service members. In time-varying interactions, junior enlisted members had longer time-to-initiation, relative to senior enlisted members and junior officers, until about 2-years postinitial diagnosis. CONCLUSION: The significant variation and documented inequities indicate that institutional data-driven policy modifications are needed to ensure timely access for those desiring care.

Opioid Prescribing Variation After Laparoscopic Cholecystectomy in the US Military Health System.

INTRODUCTION: After laparoscopic cholecystectomy (LC), there is a wide variation in opioid prescription miligram morphine equivalent dose (MED) and refills across US medical institutions. Given wide variation and opioid prescription guidelines, it is essential to conduct thorough health services research across medical, surgical, and patient-level factors that can be implemented to improve system-wide prescribing practices. Therefore, this study describes discharge MED variation and opioid refill probability after emergent and nonemergent LC. MATERIALS AND METHODS: This retrospective cohort study included medical record data of adult patients (N = 20,025) undergoing LC from January 2016 to June 2021 in the US Military Health System. Data visualizations and bivariate analyses examined prescription patterns across hospitals and evaluated the relationship between patient-level, care-level, and system-level factors and each outcome: discharge MED and opioid refill probability. Two generalized additive mixed models evaluated the relationship between predictors and each outcome. RESULTS: There was a significant variation in opioid and nonopioid pain medication prescribing practices across hospitals. While several factors were associated with discharge MED and opioid refill probability, the strongest effects were related to time period (before versus after a June 2018 Defense Health Agency policy release) and receipt of an opioid/nonopioid combination medication. Despite decreases in MED, the MED remained almost twice the recommended dose per prior research. CONCLUSIONS: Variation by hospital suggests the need for system-level changes that target genuine practice change and opioid stewardship. Inclusion of patient-reported outcomes, electronic health record decision support tools, and academic detailing programs may support system-level improvements.

Patient-centeredness and psychometric properties of the Defense and Veterans Pain Rating Scale 2.0 (DVPRS).

OBJECTIVE: This study aims to assess the patient-centeredness and psychometric properties of the Defense and Veterans Pain Rating Scale 2.0 (DVPRS) as a patient-reported outcome measure (PROM) for pain assessment in a military population. DESIGN: A critical evaluation of the DVPRS was conducted, considering its fit-for-purpose as a PROM and its patient-centeredness using the National Health Council's Rubric to Capture the Patient Voice. SETTING: The study focused on the use of the DVPRS within the Department of Defense (DoD) and Veterans Health Administration (VA) healthcare settings. SUBJECTS: The DVPRS was evaluated based on published studies and information provided by measure developers. The assessment included content validity, reliability, construct validity, and ability to detect change. Patient-centeredness and patient engagement were assessed across multiple domains. METHODS: Two independent reviewers assessed the DVPRS using a tool/checklist/questionnaire, and any rating discrepancies were resolved through consensus. The assessment included an evaluation of psychometric properties and patient-centeredness based on established criteria. RESULTS: The DVPRS lacked sufficient evidence of content validity, with no patient involvement in its development. Construct validity was not assessed adequately, and confirmatory factor analysis was not performed. Patient-centeredness and patient engagement were also limited, with only a few domains showing meaningful evidence of patient partnership. CONCLUSIONS: The DVPRS as a PROM for pain assessment in the military population falls short in terms of content validity, construct validity, and patient-centeredness. It requires further development and validation, including meaningful patient engagement, to meet current standards and best practices for PROMs.

Oscillating US Department of Defense policies and medical record documentation of gender dysphoria in service members: an observational time-series analysis.

BACKGROUND: United States military policies regarding service by transgender service members have shifted several times within the past decade. The relationships between policy changes and electronic health record documentation of gender dysphoria, a current and historic policy requisite for gender affirming care receipt, in active duty service members remain unknown. METHODS: Bayesian estimator of abrupt change, seasonality, and trend models identified changepoints in the proportion of service members who had new and then historical medical record documentation consistent with gender dysphoria from January 2015 to August 2022. Changepoints were evaluated as they related to salient military policy-related events. RESULTS: Approximately 3,853 active duty and activated National Guard or Reserve service members received a documented diagnosis corresponding to gender dysphoria from January 2015 to August 2022. Four significant changepoints were identified across both time series. Salient historical events that occurred during the changepoint periods were identified for contextualization. CONCLUSIONS: Clinical documentation of gender dysphoria oscillated with changes to policies and public statements by government leaders, which may in turn, impact military recruitment and retention. This study highlights the need for equitable policies that optimize the strength of a diverse military force. Equity-oriented monitoring is needed to continually examine the impact of military service policies on readiness and retention to support actionable, data-driven improvements to policies and their implementation.

The Relationship Between Age and 30-Day Outcomes Following Unicompartmental Versus Total Knee Arthroplasty.

BACKGROUND: Understanding the short-term complication profile following unicompartmental knee arthroplasty (UKA) versus total knee arthroplasty (TKA) can improve surgical decision-making and patient outcomes. This study aimed to determine if the difference in risk of 30-day morbidity and mortality between UKA and TKA varied based on patient age. METHODS: This retrospective study of a national quality improvement database using data from 2014 to 2020 included 403,342 patients undergoing UKA (n = 12,324) or TKA (n = 391,018). A generalized additive model evaluated nonlinear relationships between primary outcome and predictors (age, procedure, and procedure × age interaction) using a 1:5 UKA to TKA matched sample. Probabilities and odds ratios (95% confidence interval [CI]) estimated the relative risk of complications by age. RESULTS: In the generalized additive model, TKA patients relative to UKA had 1.30 odds (95% CI 1.19 to 1.43, P < 0.001) of 30-day morbidity and mortality. There was a significant nonlinear relationship between age and primary outcome (P = 0.02), such that the odds were lowest at younger ages. They increased slowly until the age of 65 years, when the slope became steeper. The interaction terms for age and procedure were not significant (P = 0.30). The 30-day probability for short-term complications of a 65-, 75-, and 85-year-olds undergoing UKA was 2.1% (95% CI 1.8 to 2.3), 2.4% (95% CI 2.0 to 2.8), and 3.2% (95% CI 2.3 to 4.1), respectively. The probability of a 65-, 75-, and 85-year-old undergoing TKA was 2.9% (95% CI 2.7 to 3.0), 3.6% (95% CI 3.3 to 3.8), and 5.5% (95% CI 4.7 to 6.3), respectively. CONCLUSIONS: Patients undergoing UKA had a quantifiable lower likelihood of morbidity or mortality than TKA at all ages. These data can provide individualized risk for UKA and TKA across the age spectrum and could be helpful in counseling patients regarding their perioperative risk. LEVEL OF EVIDENCE: III (retrospective comparative study).

Spinal Cord Stimulator Inequities Within the US Military Health System.

OBJECTIVES: Although studies have described inequities in spinal cord stimulation (SCS) receipt, there is a lack of information to inform system-level changes to support health care equity. This study evaluated whether Black patients exhaust more treatment options than do White patients, before receiving SCS. MATERIALS AND METHODS: This retrospective cohort study included claims data of Black and non-Latinx White patients who were active-duty service members or military retirees who received a persistent spinal pain syndrome (PSPS) diagnosis associated with back surgery within the US Military Health System, January 2017 to January 2020 (N = 8753). A generalized linear model examined predictors of SCS receipt within two years of diagnosis, including the interaction between race and number of pain-treatment types received. RESULTS: In the generalized linear model, Black patients (10.3% [8.7%, 12.0%]) were less likely to receive SCS than were White patients (13.6% [12.7%, 14.6%]) The interaction term was significant; White patients who received zero to three different types of treatments were more likely to receive SCS than were Black patients who received zero to three treatments, whereas Black and White patients who received >three treatments had similar likelihoods of receiving a SCS. CONCLUSIONS: In a health care system with intended universal access, White patients diagnosed with PSPS tried fewer treatment types before receiving SCS, whereas the number of treatment types tried was not significantly related to SCS receipt in Black patients. Overall, Black patients received SCS less often than did White patients. Findings indicate the need for structured referral pathways, provider evaluation on equity metrics, and top-down support.

Acute postoperative pain impact trajectories and factors contributing to trajectory membership.

BACKGROUND: Ongoing postoperative pain assessments are vital to optimizing pain management and attenuating the development of poor health outcomes after surgery. This study aimed to characterize acute multidimensional trajectories of pain impact on physical function, sleep, mood, and stress and to examine clinical characteristics and demographics associated with trajectory membership. Additionally, this study compared levels of pain intensity and prescription opioid use at 2 weeks and 1 month postoperatively across acute symptom trajectories. METHODS: Participants (N = 285) undergoing total knee arthroplasty, total hip arthroplasty, and spinal fusion procedures were recruited for this multisite prospective observational study. Longitudinal, joint k-means clustering was used to identify trajectories based on pain impact on activity, sleep, mood, and stress. RESULTS: Three distinct pain impact trajectories were observed: Low (33.7%), Improving (35.4%), and Persistently High (30.9%). Participants in the Persistently High impact trajectory reported pain interfering moderately to severely with activity, sleep, mood, and stress. Relative to other trajectories, the Persistently High impact trajectory was associated with greater postoperative pain at 1 month postoperatively. Preoperatively, participants in the Persistently High impact trajectory reported worse Pain Catastrophizing Scale scores and PROMIS Pain Interference, PROMIS Anxiety, and PROMIS Social Isolation scores than did participants presenting with other trajectories. No statistical differences in opioid use were observed across trajectories. CONCLUSIONS: Variation in acute postoperative pain impact on activity, sleep, mood, and stress exists. Given the complex nature of patients' postoperative pain experiences, understanding how psychosocial presentations acutely change throughout hospitalization could assist in guiding clinicians' treatment choices and risk assessments.

The Effectiveness of a Mindfulness-Based Intervention Integrated with Physical Therapy (MIND-PT) for Postsurgical Rehabilitation After Lumbar Surgery: A Protocol for a Randomized Controlled Trial as Part of the Back Pain Consortium (BACPAC) Research Program.

BACKGROUND: Improving pain management for persons with chronic low back pain (LBP) undergoing surgery is an important consideration in improving patient-centered outcomes and reducing the risk of persistent opioid use after surgery. Nonpharmacological treatments, including physical therapy and mindfulness, are beneficial for nonsurgical LBP through complementary biopsychosocial mechanisms, but their integration and application for persons undergoing surgery for LBP have not been examined. This study (MIND-PT) is a multisite randomized trial that compares an enriched pain management (EPM) pathway that integrates physical therapy and mindfulness vs usual-care pain management (UC) for persons undergoing surgery for LBP. DESIGN: Participants from military treatment facilities will be enrolled before surgery and individually randomized to the EPM or UC pain management pathways. Participants assigned to EPM will receive presurgical biopsychosocial education and mindfulness instruction. After surgery, the EPM group will receive 10 sessions of physical therapy with integrated mindfulness techniques. Participants assigned to the UC group will receive usual pain management care after surgery. The primary outcome will be the pain impact, assessed with the Pain, Enjoyment, and General Activity (PEG) scale. Time to opioid discontinuation is the main secondary outcome. SUMMARY: This trial is part of the National Institutes of Health Helping to End Addiction Long-term (HEAL) initiative, which is focused on providing scientific solutions to the opioid crisis. The MIND-PT study will examine an innovative program combining nonpharmacological treatments designed to improve outcomes and reduce opioid overreliance in persons undergoing lumbar surgery.

Post-total joint arthroplasty opioid prescribing practices vary widely and are not associated with opioid refill: an observational cohort study.

INTRODUCTION: Optimized health system approaches to improving guideline-congruent care require evaluation of multilevel factors associated with prescribing practices and outcomes after total knee and hip arthroplasty. MATERIALS AND METHODS: Electronic health data from patients who underwent a total knee or hip arthroplasty between January 2016-January 2020 in the Military Health System Data were retrospectively analyzed. A generalized linear mixed-effects model (GLMM) examined the relationship between fixed covariates, random effects, and the primary outcome (30-day opioid prescription refill). RESULTS: In the sample (N = 9151, 65% knee, 35% hip), the median discharge morphine equivalent dose was 660 mg [450, 892] and varied across hospitals and several factors (e.g., joint, race and ethnicity, mental and chronic pain conditions, etc.). Probability of an opioid refill was higher in patients who underwent total knee arthroplasty, were white, had a chronic pain or mental health condition, had a lower age, and received a presurgical opioid prescription (all p < 0.01). Sex assigned in the medical record, hospital duration, discharge non-opioid prescription receipt, discharge morphine equivalent dose, and receipt of an opioid-only discharge prescription were not significantly associated with opioid refill. CONCLUSION: In the present study, several patient-, care-, and hospital-level factors were associated with an increased probability of an opioid prescription refill within 30 days after arthroplasty. Future work is needed to identify optimal approaches to reduce unwarranted and inequitable healthcare variation within a patient-centered framework.

Naloxone Prescribing Associated With Reduced Emergency Department Visits in the Military Health System.

PURPOSE: The aim was to determine the association between the receipt of naloxone and emergency department (ED) visits within 60 days after the receipt of an opioid. METHODS: A retrospective cohort of individuals 18 years of age or above, enrolled in TRICARE, and were dispensed an opioid at any time from January 1, 2019, through September 30, 2020 was identified within the United States Military Health System. Individuals receiving naloxone within 5 days of the opioid dispensing date were propensity score matched with individuals receiving opioids only. A logistic regression was used to estimate the odds of an ED visit in the 60-day follow-up period after the index opioid dispense event among those co-dispensed naloxone and those receiving opioids only. RESULTS: Of the 2,136,717 individuals who received an opioid prescription during the study period, 800,071 (10.1%) met study inclusion criteria. Overall, 5096 (0.24%) of individuals who received an opioid prescription were co-dispensed naloxone. Following propensity score matching, those who received naloxone had a significantly lower odds of ED utilization in the 60 days after receiving an opioid prescription (odds ratio: 0.74, 95% CI: 0.68-0.80, P<0.001). CONCLUSION: This study highlights the importance of expanding access to naloxone in order to reduce ED utilization. Future research is needed to examine additional outcomes related to naloxone receipt and develop programs that make naloxone prescribing a routine practice.

Evaluation of an Opioid Overdose Composite Risk Score Cutoff in Active Duty Military Service Members.

OBJECTIVE: To evaluate the current cutoff score and a recalibrated adaptation of the Veterans Health Administration (VHA) Risk Index for Serious Prescription Opioid-Induced Respiratory Depression or Overdose (RIOSORD) in active duty service members. DESIGN: Retrospective case-control. SETTING: Military Health System. SUBJECTS: Active duty service members dispensed ≥ 1 opioid prescription between January 1, 2018, and December 31, 2019. METHODS: Service members with a documented opioid overdose were matched 1:10 to controls. An active duty-specific (AD) RIOSORD was constructed using the VHA RIOSORD components. Analyses examined the risk stratification and predictive characteristics of two RIOSORD versions (VHA and AD). RESULTS: Cases (n = 95) were matched with 950 controls. Only 6 of the original 17 elements were retained in the AD RIOSORD. Long-acting or extended-release opioid prescriptions, antidepressant prescriptions, hospitalization, and emergency department visits were associated with overdose events. The VHA RIOSORD had fair performance (C-statistic 0.77, 95% CI 0.75, 0.79), while the AD RIOSORD did not demonstrate statistically significant performance improvement (C-statistic 0.78, 95% CI, 0.77, 0.80). The DoD selected cut point (VHA RIOSORD > 32) only identified 22 of 95 ORD outcomes (Sensitivity 0.23), while an AD-specific cut point (AD RIOSORD > 16) correctly identified 53 of 95 adverse events (Sensitivity 0.56). CONCLUSIONS: Results highlight the need to continually recalibrate predictive models and to consider multiple measures of performance. Although both models had similar overall performance with respect to the C-statistic, an AD-specific index threshold improves sensitivity. The calibrated AD RIOSORD does not represent an end-state, but a bridge to a future model developed on a wider range of patient variables, taking into consideration features that capture both care received, and care that was not received.

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.

Variation by default: cesarean section discharge opioid prescription patterns and outcomes in Military Health System hospitals: a retrospective longitudinal cohort study.

BACKGROUND: To examine factors associated with post-Cesarean section analgesic prescription variation at hospital discharge in patients who are opioid naïve; and examine relationships between pre-Cesarean section patient and care-level factors and discharge morphine equivalent dose (MED) on outcomes (e.g., probability of opioid refill within 30 days) across a large healthcare system. METHODS: The Walter Reed Institutional Review Board provided an exempt determination, waiver of consent, and waiver of HIPAA authorization for research use in the present retrospective longitudinal cohort study. Patient records were included in analyses if: sex assigned in the medical record was "female," age was 18 years of age or older, the Cesarean section occurred between January 2016 to December 2019 in the Military Health System, the listed TRICARE sponsor was an active duty service member, hospitalization began no more than three days prior to the Cesarean section, and the patient was discharged to home < 4 days after the Cesarean section. RESULTS: Across 57 facilities, 32,757 adult patients had a single documented Cesarean section procedure in the study period; 24,538 met inclusion criteria and were used in analyses. Post-Cesarean section discharge MED varied by facility, with a median MED of 225 mg and median 5-day supply. Age, active duty status, hospitalization duration, mental health diagnosis, pain diagnosis, substance use disorder, alcohol use disorder, gestational diabetes, discharge opioid type (combined vs. opioid-only medication), concurrent tubal ligation procedure, single (vs. multiple) births, and discharge morphine equivalent dose were associated with the probability of an opioid prescription refill in bivariate analyses, and therefore were included as covariates in a generalized additive mixed model (GAMM). Generalized additive mixed model results indicated that non-active duty beneficiaries, those with mental health and pain conditions, those who received an opioid/non-opioid combination medication, those with multiple births, and older patients were more likely to obtain an opioid refill, relative to their counterparts. CONCLUSION: Significant variation in discharge pain medication prescriptions, as well as the lack of association between discharge opioid MED and probability of refill, indicates that efforts are needed to optimize opioid prescribing and reduce unnecessary healthcare variation.

The relationship between capacity and utilization of nonpharmacologic therapies in the US Military Health System.

BACKGROUND: Nonpharmacologic therapies (NPTs) are recommended as first-line treatments for pain, however the impact of expanding professional capacity to deliver these therapies on use has not been extensively studied. We sought to examine whether an effort by the US Military Health System (MHS) to improve access to NPTs by expanding professional capacity increased NPT utilization in a cohort at higher risk for pain - Army soldiers returning from deployment. METHODS: Our study involved secondary analysis of MHS workforce data derived from the Defense Medical Human Resources System Internet (DMHRSi), and healthcare utilization data obtained from two ambulatory record systems of the Military Health System (MHS) for a sample of 863,855 Army soldiers previously deployed to Iraq or Afghanistan over a 10-year period (2008-2017). We measured clinical provider capacity in three occupational groups responsible for pain management at 130 military treatment facilities (MTFs): physical therapy, chiropractic, and behavioral health, measured annually as full-time equivalence per 100,000 patients served at each MTF. Utilization in both direct and purchased care settings was measured as annual mean NPT users per 1000 sample members and mean encounters per NPT user. Generalized estimating equation models estimated the associations of facility-level occupational capacity measures and facility-level utilization NPT measures. RESULTS: In 2008, nearly all MTFs had some physical therapist and behavioral health provider capacity, but less than half had any chiropractor capacity. The largest increase in capacity from 2008 to 2017 was for chiropractors (89%) followed by behavioral health providers (77%) and physical therapists (37%). Models indicated that increased capacity of physical therapists and chiropractors were associated with significantly increased utilization of six out of seven NPTs. Acupuncture initiation was associated with capacity increases in each occupation. Increased professional capacity in MTFs was associated with limited but positive effects on NPT utilization in purchased care. CONCLUSIONS: Increasing occupational capacity in three professions responsible for delivering NPTs at MTFs were associated with growing utilization of seven NPTs in this Army sample. Despite increasing capacity in MTFs, some positive associations between MTF capacity and purchased care utilization suggest an unmet need for NPTs. Future research should examine if these changes lead to greater receipt of guideline-concordant pain management.

Development and Implementation of an Online Pain Management Continuing Education Program.

BACKGROUND: Multiple studies indicate a lack of pain management training across a range of healthcare specialties. The online Joint Pain Education Program (OJPEP) was created to provide content covering various topics that range from general pain science to integrative care to pain management. The present study evaluates the feasibility of an interdisciplinary, self-guided, online pain management continuing education program, the OJPEP. PARTICIPANTS/SUBJECTS: A total of 228 learners participted in this study. Of the 228 learners, 58 learners identified as registered nurses and 12 learners identified as nurse practitioners. DESIGN: Prospective single-arm education feasibility study. METHODS: Potential learners were provided invitations to participate via emails from clinic leadership and postings to hospital intranet websites. Learners registered online and could select up to eight modules, based on the materials developed from a Department of Defense/Veterans Administration project. Learners evaluated their satisfaction with module quality and applicability. RESULTS: A variety of providers, predominately non-prescribers, across many health care specialties, registered for modules. Across all modules except one, less than half of participants who registered completed the selected module. Time stamps indicated many learners skipped module content. Of those who completed the continuing education evaluation to obtain certificates, the majority indicated the content was of high-quality, appropriate, and evidence-based. One-third to approximately one-half of learners indicated that they would apply content in their clinical practice. Completion of the intended 3-month follow-up survey was poor. CONCLUSIONS: Though modules were acceptable per learner responses, future work is needed to: develop modules that are more engaging (e.g., interactive) and applicable to learners; and improve implementation methods to include dissemination and evaluation metrics.

Policy Facilitators Versus Structural Barriers: Integrative Therapy Telehealth Changes in the United States During the COVID-19 Pandemic.

Introduction: Complementary and integrative therapies such as physical therapy (PT) and occupational therapy (OT) have been shown to improve functional outcomes and reduce opioid use. Due to the COVID-19 (or SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2]) pandemic, these therapies are switching to telehealth and telemedicine practices, but access and utilization may be limited due to state policies and social vulnerability. Objective: The objective of this cross-sectional analysis was to evaluate the policy changes to telehealth provisions during the pandemic and the degree to which structural barriers could stymie the intended impact of these policies (e.g., PT/OT accessibility). Materials and Methods: Our analysis examined each states' telehealth policies in relation to PT/OT, ranked their telehealth readiness, identified relationships between existing policies and opioid prescription rates, and discussed how social determinants of health may be associated with telehealth availability and accessibility. Results: Approximately two of five states have both telehealth and telemedicine policies, whereas the majority of states had either a PT- or OT-specific policy in place. In addition, almost all states and the District of Columbia (90%) had general telehealth/medicine policy changes as a result of the pandemic. Discussion: Although such policy changes could reduce COVID-19-related barriers, the degree to which these policies can have a large and long-lasting impact may be contingent on structural barriers. Many states that lack broadband access and have high social vulnerability need more improvements to ensure the utilization of telehealth care, including PT and OT. Conclusion: Despite the policies expanding PT/OT telehealth capabilities, structural barriers may further exacerbate inequities in care accessibility.

Changes in actigraphy metrics associated with PROMIS measures after orthopaedic surgery.

AIM: This study examined the feasibility of integrating actigraphy devices into orthopaedic surgical settings to assess the concurrent validity between objective actigraphy data and PROMIS measures. Additionally, the association between changes in actigraphy data and longitudinal changes in PROMIS measures was examined. METHODS: Data were collected from 17 participants using actigraphy devices the week prior to and after orthopaedic surgery from 02/2019 to 03/2020. Participants completed PROMIS measures (Physical Function, Sleep Disturbance, Pain Interference) preoperatively and up to 6 months postoperatively. Nonparametric correlations (rs ) assessed for concurrent validity. Linear mixed-effects models examined the association between changes in actigraphy data and PROMIS measures. RESULTS: Prolonged wake after sleep onset was associated with increased sleep disturbances (rs = 0.49; p = 0.045) and pain interference (rs = 0.51; p = 0.04). Changes in pain interference were correlated with increased awakenings (rs = 0.54; p = 0.03). Increased wake after sleep onset was associated with worsening sleep disturbance (ß = 0.12; p = 0.01) and pain interference scores over the postoperative period (ß = 0.12; p = 0.02). CONCLUSIONS: This study is among the first to examine changes in objective actigraphy data and longitudinal PROMIS measures following orthopaedic surgery and illustrates the feasibility of incorporating actigraphy into surgical settings to evaluate postoperative recovery.

Predictors of continued opioid use 6 months after total joint arthroplasty: a multi-site study.

PURPOSE: Continued opioid use after total knee and hip arthroplasty (TKA/THA) is well-documented and associated with both surgical and patient-reported factors. Research examining the combined effects of a multitude of factors on continued, and even chronic, opioid use in a systematic algorithmic manner is lacking. This study prospectively evaluated the combined effect of patient-related and surgical factors associated with continued opioid use after TKA/THA. METHODS: From 2016 to 2018, 198 participants undergoing TKA or THA were recruited from two tertiary care facilities. Participants completed surveys before surgery and at 2 weeks, 1, 3, and 6 months following surgery. A LASSO approach, followed by an exhaustive covariate selection procedure, was used to build a multivariable mixed-effects logistic regression model estimating the odds ratio of continued postoperative opioid use based on surgical factors and patient-reported factors. RESULTS: Approximately half of the participants underwent either TKA (49%) or THA (51%). Preoperatively, 15% of participants reported taking opioid medication. Opioid use decreased from 68% at 2-week follow-up to 7% by 6 months. In addition, preoperative opioid use (95% CI 1.07-4.37), increased pain (95% CI 1.21-1.62), elevated preoperative Pain Catastrophizing Scale scores (95% CI 1.01-1.04), lower Physical Function scores (95% CI 0.87-0.95), and participants undergoing TKA, compared to THA, (95% CI 0.25-0.67) were found to be significantly associated with continued postoperative opioid use up to 6 months. CONCLUSION: Preoperative opioid use, average pain, reduced physical function, and TKA were significantly associated with continued postoperative opioid use. Findings illustrate the need for preoperative and longitudinal assessment of patient-reported outcomes to mitigate poor postoperative pain outcomes. LEVEL OF EVIDENCE: II.

Implementation of the Uniformed Services University Pain Registry Biobank: A Military and Veteran Population-Focused Biobank and Registry.

OBJECTIVE: The objective of this overview is to discuss the development, implementation, data content, and structure of the Uniformed Services University Pain Registry Biobank. Additionally, procedures and policies for accessing samples for pain-related research purposes are detailed. DESIGN: Cross-sectional overview. SETTING: Multiple military treatment facilities. SUBJECTS: Adult beneficiaries seeking care within the Military Health System. METHODS: Participants complete a baseline battery of biopsychosocial survey measures, including Patient-Reported Outcomes Measurement Information System (PROMIS®) measures, and provide biological samples (e.g., blood and saliva). Relevant health history, including medications and surgical history, is extracted from medical records. During the course of the subsequent year, enrolled participants complete surveys and provide biological samples at 3 months, 6 months, and 12 months. Thereafter, participants are contacted once annually to complete self-reported assessments and provide biological samples. RESULTS: In the first year alone, 86 subjects have participated in the Uniformed Services University Pain Registry Biobank and provided 390 observations (e.g., biological samples and biopsychosocial patient-reported outcomes). The Uniformed Services University Pain Registry Biobank's integration of biological samples, patient-reported outcomes, and health record data over a longitudinal period across a diverse sample recruited from multiple military facilities addresses many of the limitations faced by other pain-related registries or biorepositories. CONCLUSIONS: The Uniformed Services University Pain Registry Biobank will serve as a platform for conducting research closely aligned with the Federal Pain Research Strategy. The inclusion of active duty service members, beneficiaries, and civilians living with and without acute or chronic pain provides a unique data repository for all investigators interested in advancing pain science.

Relationship Between Post-Traumatic Stress Disorder Symptoms and Chronic Pain-Related Symptom Domains Among Military Active Duty Service Members.

OBJECTIVE: This study examined the relationships between symptom domains relevant to post-traumatic stress disorder (PTSD) diagnosis, PTSD screening, and chronic pain-related symptoms (pain intensity, pain interference, physical function, fatigue, depression, anxiety, anger, satisfaction with social roles) experienced by active duty military service members with chronic pain. DESIGN: ross-sectional study. SETTING: This study was conducted at the Interdisciplinary Pain Management Center (IPMC) at Madigan Army Medical Center between 2014 and 2018. SUBJECTS: Active duty service members receiving care at IPMC (n = 2745) were included in this study. METHODS: Independent sample t test was conducted to compare pain intensity and pain-related measures of physical, emotional, and social functioning among patients with and without a PTSD diagnosis or PTSD positive screen (≥3 symptoms). Relative weight analysis was used to identify the relative importance of each PTSD symptom cluster (e.g., intrusion, avoidance, hyperarousal, emotional numbness) to pain and related domains. RESULTS: Approximately 27.9% of the patients had a positive screen for PTSD, and 30.5% of the patients had a PTSD diagnosis. Patients with PTSD diagnosis and positive screening had higher pain interference and lower physical function and social satisfaction scores (P < 0.001) and had increased anger, anxiety, fatigue, and depression scores (P < 0.001). Emotional numbness accounted for the largest proportion of variance in average pain intensity, pain interference, and psychological functioning, and avoidance accounted for the largest proportion of variance in physical function. CONCLUSION: To improve treatment effectiveness and overall functioning for active duty military patients, integrated treatment and therapies targeted to reducing chronic pain and PTSD symptoms (focus on emotional numbness and avoidance) are recommended.
