RESUMEN
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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

BACKGROUND: Ketamine is routinely used within the context of combat casualty care. Despite early concerns that ketamine administration may be associated with elevated risk of posttraumatic stress disorder (PTSD), more recent evidence suggests no relationship. Because PTSD occurs with regular frequency in Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) Service Members (SMs) and combat-related injuries are associated with higher likelihood of PTSD, it is important to investigate the relationship between ketamine exposure during inpatient medical and surgical care and PTSD symptoms in OIF/OEF SMs. METHODS: Medical record data from OIF/OEF SMs medically evacuated from combat (N = 1158) included demographic characteristics, injury severity, body areas injured, and PTSD Checklist (PCL) scores. The primary analysis assessed the association between ketamine versus nonketamine exposure on positive PTSD screen (logistic regression) and PCL scores (linear regression) after using 1:1 propensity score matching to adjust for available potential confounding variables. Because there were 2 primary outcomes, the binary positive PTSD screen (yes/no) and continuous PCL score, the significance level was set at P ≤ .025. In sensitivity analyses, propensity scores were used to match ketamine to nonketamine records in a 1:4 ratio, as well as to conduct inverse probability treatment weighting (IPTW). Regressions examining the relationship between ketamine exposure and outcomes were repeated for unconditional, 1:4 matching, and IPTW models. RESULTS: In the sample, 107 received ketamine and 1051 did not. In the logistic regression, the probability of a positive PTSD screen was not significantly different between ketamine versus nonketamine patients (odds ratio [OR] = 1.28; 95% confidence interval [CI], 0.48-3.47; P = .62). In the linear regression, PCL scores were not significantly different between ketamine versus nonketamine patients (mean difference = 1.98 [95% CI, -0.99 to 4.96]; P = .19). The results were consistent in the unconditional, 1:4 matching, and IPTW models. CONCLUSIONS: No differences in PTSD screening risk or symptom levels between ketamine exposed and nonexposed were found. Given the small sample size, wide CIs of the effects, and additional confounds inherent to retrospective studies, future studies are needed to examine the complex relationships between ketamine and psychological symptoms.

OBJECTIVES: To investigate pain catastrophizing presentations up to 6 months postoperatively and subsequent changes in pain intensity and physical function. DESIGN: Prospective observational multisite study. SETTING: Two tertiary care facilities between 2016 and 2019. PARTICIPANTS: Adult patients (N=348) undergoing a mastectomy, thoracic surgery, total knee or hip arthroplasty, spinal fusion, or major abdominal surgery. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Pain Catastrophizing Scale scores, Defense and Veterans Pain Rating Scale, average pain intensity, and Patient Reported Outcomes Measurement Information System (PROMIS) physical function. RESULTS: Four pain catastrophizing trajectories were identified in 348 surgical patients during the 6 months of postoperative recovery: stable, remitting, worsening, and unremitting. Linear mixed-effects models found that the unremitting trajectory was associated with higher pain intensity over time. The average pain intensity of participants in the remitting trajectory was estimated to decrease at a faster rate over the 6 months after surgery than pain of other trajectories, despite participants reporting high preoperative Pain Catastrophizing Scale and pain scores. Worsening and unremitting trajectories were associated with reduced physical function. Preoperative average pain intensity scores were not associated with postoperative physical function scores, nor were participants' preoperative physical function scores associated with average pain intensity scores postoperatively. Prolonged hospitalization, smoking, and preoperative opioid prescriptions were associated with the unremitting trajectory. CONCLUSIONS: Findings suggest that preoperative pain catastrophizing scores alone may not be adequate for estimating long-term patient-reported outcomes during postoperative rehabilitation. Pain catastrophizing has a dynamic presentation and is associated with changes in pain intensity and physical function up to 6 months postoperatively. Routine assessments can inform the delivery of early interventions to surgical patients at risk of experiencing a pain catastrophizing trajectory associated with suboptimal outcomes during rehabilitation.

OBJECTIVE: Postsurgical follow-up calls enable nurses to assess a patient's condition, provide tailored education, and improve the patient's experience. Despite the benefits, barriers to phone-based assessments may include patient nonresponse and lack of time due to demanding clinical schedules. The purpose of this trial was to examine the feasibility and utility of a smartphone app, mCare, for assessing pain, pain impact, and peripheral nerve block effects in patients. DESIGN: Pilot randomized control trial. SETTING AND PATIENTS: Eligible patients at a military treatment facility undergoing same-day surgery were randomized to the mCare group (N = 24) or the standard-of-care telephone (N = 26) group. RESULTS: Outcomes included initial response (assessment completion) rates and participant and nurse satisfaction. There were no differences in the response rates upon initial contact attempt, and patients in both groups reported similar levels of satisfaction and convenience. Nurses reported greater satisfaction with the app compared with standard-of-care telephone calls. CONCLUSIONS: Before wider implementation, further considerations of app-based assessment need to be fully explored.

OBJECTIVES: The National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) is a multidimensional screening system evaluating biopsychosocial factors affecting pain and functioning. Using a military sample, the current study 1) examined the structure and domains of the PROMIS, the Defense and Veterans Pain Rating Scale 2.0 (DVPRS), and the Pain Catastrophizing Scale (PCS) within a presurgical setting and 2) examined the relationship of these variables to pre- and postsurgical opioid use. METHODS: This cross-sectional study included 279 adult patients scheduled for surgery at the Walter Reed National Military Medical Center and a validation sample of 79 additional patients from the Naval Medical Center, San Diego. PROMIS, DVPRS, PCS, and opioid use data were collected before surgery. Exploratory factor analysis and confirmatory factor analysis identified the latent structure for the measures. A structural equation model (SEM) examined their relationship to pre- and postsurgical opioid use. RESULTS: Two latent factors represented Psychosocial Functioning (PROMIS Depression, PROMIS Anxiety, and PROMIS Social Isolation) and Pain Impact (DVPRS, PROMIS Pain Interference, PROMIS Physical Functioning). The remaining PROMIS scales did not load onto a single factor. In the SEM, the two latent factors and PCS were significantly related to pre- and postsurgical opioid use. CONCLUSIONS: This study highlights the utility and relative ease of using a convenient multidimensional assessment in presurgical settings. Using such an assessment can help provide targeted interventions for individuals who may be at greatest risk for negative postsurgical outcomes.
