A network analysis of pain intensity and pain-related measures of physical, emotional, and social functioning in US military service members with chronic pain.

OBJECTIVE: The purpose of this study was to apply network analysis methodology to better understand the relationships between pain-related measures among people with chronic pain. METHODS: We analyzed data from a cross-sectional sample of 4614 active duty service members with chronic pain referred to 1 military interdisciplinary pain management center between 2014 and 2021. Using a combination of Patient-Reported Outcomes Measurement Information System measures and other pain-related measures, we applied the "EBICglasso" algorithm to create regularized partial correlation networks that would identify the most influential measures. RESULTS: Pain interference, depression, and anxiety had the highest strength in these networks. Pain catastrophizing played an important role in the association between pain and other pain-related health measures. Bootstrap analyses showed that the networks were very stable and the edge weights accurately estimated in 2 analyses (with and without pain catastrophizing). CONCLUSIONS: Our findings offer new insights into the relationships between symptoms using network analysis. Important findings highlight the strength of association between pain interference, depression and anxiety, which suggests that if pain is to be treated depression and anxiety must also be addressed. What was of specific importance was the role that pain catastrophizing had in the relationship between pain and other symptoms suggesting that pain catastrophizing is a key symptom on which to focus for treatment of chronic pain.

The Role of Psychological Factors in Chronic Pain Treatment Outcomes in the Military.

PURPOSE: Chronic pain treatment in the military includes complementary and integrative health (CIH) therapies that may affect psychological factors such as pain catastrophizing, chronic pain acceptance, pain self-efficacy, and patient activation. The unique roles that psychosocial factors play in how CIH approaches reduce pain are not clear. This study examined if a holistic pain management program improved pain outcomes through psychological mediators in service members with chronic pain. DESIGN: Secondary analysis of a clinical trial. METHODS: Active-duty service members (n = 210) were randomly assigned to a 3-week course of standard rehabilitative care or standard rehabilitative care combined with CIH therapies. Both treatments were followed by a 3-week functional restoration program. Study measures were completed pre- and post-treatment using the Military Health System's Pain Assessment Screening Tool and Outcomes Registry. Mediation analyses tested the indirect effects of the change in psychological factors before functional restoration on the change in pain impact (e.g., pain intensity, pain interference, functional status) after functional restoration. RESULTS: All psychological factors except for chronic pain acceptance were related to improved pain impact (p<.05). Furthermore, a change in psychological factors prior to functional restoration was related to the change in pain impact after functional restoration. However, the addition of CIH therapies to standard rehabilitative care did not result in changes in pain outcomes mediated by the psychological factors. CONCLUSIONS: Although psychological factors were related to pain outcomes, the effect of CIH therapies on chronic pain did not occur via a change in the four psychological factors.

Patterns of Change in Pain-related Physical, Mental, and Social Health Outcomes in a Military Population.

OBJECTIVE: Military persons frequently experience pain conditions stemming from noncombat and combat injuries. This study assessed the patterns of change over time and the associations of pain intensity and interference with physical, mental, and social health domains in a military sample. METHODS: A secondary analysis of Pain Assessment Screening Tool and Outcomes Registry (PASTOR) was conducted using data collected over 10 months. Participants selected for analysis completed ≥3 assessments with an interval of ≥14 days between assessments. The Defense and Veterans Pain Rating Scale (DVPRS) measured average and worst pain intensity, and Patient-Reported Outcomes Measurement Information System (PROMIS®) T-scores measured pain and health outcomes. RESULTS: The sample (N = 190) majority reported being active duty (96%); serving in the U.S. Army (93%); and being enlisted (86%). The percent difference from assessment one to assessment three showed improvement for DVPRS average pain (-4.85%) and worst pain (-2.16%), and PROMIS Pain Interference T-score (-1.98%). Improvements were observed for all PROMIS outcomes except depression. The Defense and Veterans Pain Rating Scale average and worst pain intensity and PROMIS pain interference were strongly correlated with physical function. Multilevel models showed that an increase in average and worst pain, and pain interference were associated with a decrease in satisfaction with social roles. CONCLUSION: Analysis identified patterns of change over time in physical, mental, and social health outcomes, as well as associations important to understanding the complexities of pain. This work has implications for pain management nursing in ambulatory settings where ongoing collection and analyses of multivariable outcomes data can inform clinical care.

Experiences of Military Primary Care Providers During Chronic Pain Visits: A Qualitative Descriptive Study.

OBJECTIVE: Chronic pain complaints are the second most common reason for outpatient primary care visits, yet a comprehensive assessment of the processes and experiences of providers during a chronic pain visit is still lacking. This qualitative descriptive study aimed to conceptualize the processes and experiences that military primary care providers go through while they assess and manage chronic pain. SETTING: Single U.S. Army medical center. METHODS: Semistructured interviews with 12 military primary care providers. Interviews were audio-recorded, transcribed, and coded with the use of qualitative software. Transcripts were analyzed with thematic analysis to identify emergent themes. RESULTS: Three broad themes with associated subthemes captured the processes and the providers' experiences: 1) comprehending the pain story-asking the right questions about pain impact, navigating through the complexities of the pain story, and conveying understanding of the pain story back to the patient; 2) optimizing the pain story-perceiving provider-patient disconnect on pain management goals, resetting realistic goals, creating an optimal individualized treatment plan, and evaluating treatment effectiveness; and 3) empathetic and therapeutic engagement with patients-trusting patients and fostering the patient-provider relationship. A thematic map illustrates these provider experiences. CONCLUSIONS: During chronic pain visits, the provider-patient disconnect on the goals of chronic pain treatment presents a considerable challenge. Further in-depth studies on addressing provider-patient disconnect are warranted to identify solutions, which would help providers communicate realistic chronic pain management expectations to patients. The themes and subthemes described in this study could serve as a guide for directing strategies to improve chronic pain visits in primary care.

Use of Complementary and Integrative Health Therapies Before Intensive Functional Restoration in Active Duty Service Members with Chronic Pain.

OBJECTIVE: Psychosocial factors are known to predict chronic pain, and the use of complementary and integrative health (CIH) therapies to address pain is emerging among the military population. However, conflicting results on pain outcomes warrant additional research. This study aimed to 1) evaluate the benefit of adding a CIH pain management program to standard rehabilitative care (SRC), as compared with SRC alone, as a precursor to an intensive functional restoration (FR) program; 2) identify factors that predict improvement in pain outcomes after treatment; and 3) determine the proportion of participants who experience a clinically meaningful response. DESIGN: Pragmatic randomized controlled clinical trial. Participants were randomized to a 3-week course of either SRC alone or SRC+CIH (stage 1), followed by a 3- to 6-week course of FR (stage 2). SUBJECTS: Active duty service members with chronic pain. METHODS: Participants completed either SRC alone or SRC+CIH (stage 1), followed by a course of FR (stage 2). Patient-reported and provider-determined outcomes were collected at baseline, after stage 1, and after stage 2. A covariance pattern model with an unstructured residual covariance matrix was used to compare treatment arms while accounting for dependency due to repeated measurements. RESULTS: A total of 210 service members participated. Most were in the Army (82%) and were male (84%). Participants randomized to the SRC+CIH intervention had greater improvement in the pain impact score than did those in the SRC-alone group. Predictors of outcomes were baseline impact score, anger, depression, and educational status. CONCLUSIONS: This study found that military service members with the highest pain impact benefit the most from interdisciplinary pain care.

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.

Chronic Musculoskeletal Pain: Nonpharmacologic, Noninvasive Treatments.

Chronic low back pain, neck pain, hip and knee osteoarthritis, and fibromyalgia are the most common types of chronic musculoskeletal pain. Because no individual therapy has consistent benefit, a multimodal treatment approach to chronic musculoskeletal pain is recommended. Many nonpharmacologic, noninvasive treatment approaches yield small to moderate improvement and can be used with pharmacologic or more invasive modalities. Systematic reviews and guidelines support the effectiveness of various forms of exercise in improving pain and function in patients with chronic pain. Cognitive behavior therapy and mindfulness techniques appear to be effective for small to moderate short- and long-term improvement of chronic low back pain. Cognitive behavior therapy may also be effective for small short- and intermediate-term improvement of fibromyalgia. Spinal manipulation leads to a small benefit for chronic neck and low back pain. Acupuncture has a small to moderate benefit for low back pain and small benefit for nonpain fibromyalgia symptoms. Massage or myofascial release yields a small improvement in low back pain, hip and knee osteoarthritis, and fibromyalgia. Low reactive level laser therapy may provide short-term relief of chronic neck and low back pain, and ultrasound may provide short-term pain relief for knee osteoarthritis. Multidisciplinary rehabilitation may be effective for short- and at least intermediate-term improvement in pain and function for chronic low back pain and fibromyalgia. Patients should be encouraged to engage in a variety of therapies aligned with their preferences and motivation.

Role of Pain Catastrophizing in the Effects of Cognitive Behavioral Therapy for Chronic Pain in Different Subgroups: An Exploratory Secondary Data Analysis Using Finite Mixture Models.

INTRODUCTION: Providing effective treatment for debilitating chronic pain is a challenge among many populations including military service members. Cognitive behavioral therapy for chronic pain (CBT-CP) is a leading psychological pain treatment. Pain catastrophizing is a pivotal mediator of pain-related outcomes. The purpose of this study was (1) to identify patient subgroups who differ in response to CBT-CP and (2) to explore the characteristics that define these patient subgroups. The overall goal was to obtain a better understanding of factors that may influence response to CBT-CP. MATERIALS AND METHODS: This study was a secondary analysis of data from a clinical trial of 149 U.S. active duty service members with chronic pain. Participants underwent group-based CBT-CP for 6 weeks and completed pre- and posttreatment assessments. Finite mixture models were employed to identify subgroups in treatment response, with pain impact score as the primary outcome measure. RESULTS: We identified two classes of nearly equal size with distinct pain impact responses. One class reported improved pain impact scores following CBT-CP. This improvement was significantly associated with lower (better) baseline depression scores and greater improvement in posttreatment pain catastrophizing. In contrast, the other class reported slightly worse mean pain impact scores following CBT-CP treatment; this response was not related to baseline depression or change in pain catastrophizing. CONCLUSIONS: Our findings demonstrate that a sizable proportion of individuals with chronic pain may not respond to group-based CBT-CP and may require a more individualized treatment approach.

Pain Catastrophizing and Its Association with Military Medical Disability Among US Active Duty Service Members with Chronic Predominately Musculoskeletal Pain: A Retrospective Cohort Analysis.

Context: Pain catastrophizing is characterized by negative emotional and cognitive responses to pain and is a predictor of work-related disability. Its association with military medical disability has not been studied. Objective: To (1) identify the pain catastrophizing scale (PCS) score cut point most strongly associated with military medical disability, (2) measure the difference in rate of disability between service members with baseline PCS scores above versus below the cut point, and (3) determine if improvement in PCS score during pain specialty care is associated with decreased likelihood of disability. Methods: This was a retrospective cohort analysis comparing PCS scores collected from US Army active duty service members at time of initial visit to an interdisciplinary pain management center and periodically during pain treatment. Outcome was determination during the following year of a military service-disqualifying disability. Results: Receiver operating characteristic (ROC) curves determined that a PCS score of 20 was the single cut point most closely associated with subsequent disability. Kaplan-Meier curves showed significantly higher disability rate during the following year among those with baseline PCS scores ≥20 (52%) compared to those with lower scores (26%). Scheffe-adjusted contrasts showed that service members with PCS scores ≥20 whose scores improved to <20 at follow-up were significantly less likely to have a medical disability (42.6%; 95% CI, 0.07-0.58) than those whose PCS score remained ≥20 (76.3%; 95% CI, 68.0%-84.7%). Conclusion: A PCS score cut point of 20 distinguishes between high versus low likelihood of disability among service members. Those with high baseline PCS score had twice the likelihood of disability than those with low scores. Service members who decreased their PCS score from high to low during pain specialty care had lower likelihood of disability. Prospective research is needed to determine if treatments that lower pain catastrophizing yield reduced likelihood of subsequent disability.

Tools, Time, Training, and Team-Military Primary Care Providers' Perspectives on Improving Chronic Pain Assessment and Management.

INTRODUCTION: Primary care providers are on the front lines of chronic pain management, with many reporting frustration, low confidence, and dissatisfaction in handling the complex issues associated with chronic pain care. Given the importance of their role and reported inadequacies and dissatisfaction in managing this challenging population, it is important to understand the perspectives of primary care providers when considering approaches to chronic pain management. This qualitative descriptive study aimed to comprehensively summarize the provider challenges and suggestions to improve chronic pain care in military primary care settings. MATERIALS AND METHODS: Semi-structured interviews with 12 military primary care providers were conducted in a single U.S. Army medical center. All interviews were audio-recorded and lasted between 30 and 60 minutes. Interview transcripts were analyzed using ATLAS 9.0 software. Narratives were analyzed using a general inductive approach to content analysis. The Framework Method was used to organize the codes and emergent categories. All study procedures were approved by the Institutional Review Board of the University of Washington. RESULTS: Four categories captured providers' challenges and suggestions for improving chronic pain care: (1) tools for comprehensive pain assessment and patient education, (2) time available for each chronic pain appointment, (3) provider training and education, and (4) team-based approach to chronic pain management. Providers suggested use of the Pain Assessment Screening Tool and Outcomes Registry, more time per visit, incorporation of chronic pain care in health sciences curriculum, consistent provider training across the board, insurance coverage for complementary and integrative therapies, patient education, and improved access to interdisciplinary chronic pain care. CONCLUSIONS: Lack of standardized multifaceted tools, time constraints on chronic pain appointments, inadequate provider education, and limited access to complementary and integrative health therapies are significant provider challenges. Insurance coverage for complementary and integrative health therapies needs to be expanded. The Stepped Care Model of Pain Management is a positive and definite stride toward addressing many of these challenges. Future studies should examine the extent of improvement in guidelines-concordant chronic pain care, patient outcomes, and provider satisfaction following the implementation of the Stepped Care Model of Pain Management in military health settings.

Effectiveness of Telementoring in Improving Provider Knowledge, Attitudes, and Perceived Competence in Managing Chronic Pain: A Mixed Methods Study.

INTRODUCTION: Telementoring is an evidence-based approach to meet the educational needs of primary care providers (PCPs) and to improve the quality of chronic pain care. This mixed methods study evaluated the effectiveness of pain management telementoring in improving provider knowledge, attitudes, and perceived competence. MATERIALS AND METHODS: The study was conducted at Madigan Army Medical Center. Using a non-randomized quasi-experimental approach, 25 providers were assigned to intervention arm and control arm (14 intervention and 13 control). Providers in the intervention group attended telementoring sessions. Videoconference technology was used to deliver weekly 90-minute TelePain sessions to the PCPs in the intervention group. The first 25-30 minutes of each session consisted of a didactic presentation led by a panel of interdisciplinary pain management clinicians. During the remaining 60 minutes, all PCPs in the intervention group presented clinical histories and asked specific management questions regarding patients of their choosing. An interdisciplinary panel of pain management clinicians provided telementoring consultations. The panel included experts from pain medicine, primary care, psychology or psychiatry, chiropractic, clinical pharmacy, and nursing. Changes in provider knowledge, attitudes, and perceived competence were evaluated using the Knowledge and Attitudes Survey Regarding Pain, KnowPain-12, and the Perceived Competence Scale (n = 23; 12 intervention and 11 control). Qualitative interviews were conducted among a subset of providers (n = 12; 8 intervention and 4 control), and provider narratives were analyzed using content analysis. RESULTS: Increased provider knowledge (Z = 2.0, P = .046 [KnowPain-12]) and perceived competence (Z = 2.1, P = .033) were observed among intervention group providers. Provider narratives supported more implementation of non-pharmacological pain management strategies, use of strategies to engage patients in reducing reliance on opioids, and perception of TelePain as a helpful resource especially in the context of inadequate preparation in chronic pain management during professional training. CONCLUSIONS: Telementoring may hold significant potential to support providers in their efforts to decrease use of prescription opioids. Overall, this study provides further support for the value of telementoring in improving comprehensive chronic pain management in military settings.

Pattern of Cumulative Treatment Hours on Pain Impact and PROMIS Outcomes.

INTRODUCTION: Participation in interdisciplinary treatments is associated with improvement in pain intensity, physical function, and additional pain-related outcome domains. However, the effect of cumulative treatment hours on outcomes remains unknown among military patients. The present analysis examined the relationship between cumulative interdisciplinary treatment hours and pain management outcomes at a single interdisciplinary pain management center (IPMC). MATERIALS AND METHODS: This is a retrospective observational study of data previously collected as standard of care at the Madigan Army Medical Center, approved by the Institutional Review Board. We included patients who received treatment at the IPMC and completed at least two self-report assessment batteries: one at baseline and at least one between 90 and 180 days after baseline (n = 882). The primary outcome was pain impact. Secondary outcomes included fatigue, depression, anxiety, and sleep-related impairment. RESULTS: Generalized additive models indicated that cumulative treatment hours were significantly associated with improvement in pain impact, fatigue, and depression. Patients who had higher baseline pain impact, who had mild or no depressive symptoms, and who were >40 years of age had greater improvements in pain impact following treatment, relative to those with lower pain impact, moderate-to-severe depressive symptoms, and were 40 years of age or younger, respectively. Additional research is needed to elucidate the effect of different therapies and additional patient factors in understanding the "therapeutic dose" of interdisciplinary pain management. CONCLUSIONS: A higher number of cumulative treatment hours was associated with improvement of pain impact, fatigue, and depression among military personnel receiving interdisciplinary pain treatment. At least 30 hours of sustained interdisciplinary treatment appears to be the threshold for improvement in pain impact and related outcomes.

Predictors of Sustained Response to Functional Restoration in a Military Population.

INTRODUCTION: The purpose of this study was to determine if improvement in pain impact and functional performance following a functional restoration (FR) program was sustained up to 6 months posttreatment and to identify predictors of sustained improvement. MATERIALS AND METHODS: Secondary analysis of data collected during randomized clinical trial. Study population included 108 US active duty service members who completed an FR program, as well as 3- and/or 6-month follow-up assessments. Primary outcome measure was the NIH Research Task Force (pain) impact score (PIS). Secondary outcome was a composite functional performance measure of treadmill, lifting, and carrying tolerances. Variables analyzed to determine their predictive value included demographics; treatment hours; measures of pain intensity, function, mood, sleep, social satisfaction, pain catastrophizing, kinesiophobia, self-efficacy, pain acceptance, patient activation, functional performance, and neuropathic pain. RESULTS: Mean PIS and functional performance improved significantly immediately following FR, but after 6 months, only improvement in functional performance sustained. Responder analysis showed that 6 months after FR, 42% of participants reported improvement that exceeded the minimal clinically important difference in PIS or functional performance. Predictors of sustained PIS improvement included younger age, absence of neuropathic pain features, less self-rated disability, better baseline functional performance, and worse baseline PIS. Predictors of sustained functional performance improvement included more treatment hours, lower baseline pain catastrophizing, and lower baseline functional performance. CONCLUSIONS: This study supports the investment of treatment time in FR to yield sustained clinically meaningful improvement, as observed in over 40% of this study's military participants. Pretreatment predictors of sustained response included lower pain catastrophizing and absence of neuropathic pain. Further research is needed to determine if treatments that improve pain catastrophizing and neuropathic pain will result in sustained improvement in pain impact and functional performance following FR program participation.

Use of a treadmill, lift, and carry battery as a composite functional performance test: analysis of data from a pragmatic randomized controlled trial in a military population participating in a functional restoration program.

BACKGROUND: The treadmill, lift, and carry (TLC) battery is a composite functional performance test created to measure the effectiveness of a functional restoration (FR) program in a military population. PURPOSE: To determine the validity, reliability, and minimal clinically important differences (MCIDs) of the individual tests and the composite TLC battery. METHODS: We assessed the validity by mean differences, effect sizes, and standardized response means pre- and post-FR; and by correlations between the TLC battery and other established measures. We assessed reliability by correlating pre- and post-FR scores. We used principal component analysis (PCA) to create a composite measure. We determined MCIDs via distribution methods and receiver operator curve analysis. RESULTS: There were significant (p < .001) mean changes and large effect sizes (0.6-0.8) pre- to post-FR. Pre- and posttest Spearman's correlations ranged from 0.5 to 0.6. Spearman's correlations between TLC battery scores and other measures were small (± 0.3-0.4) and significant (p < .001). PCA supported use of a single-component composite. MCIDs were treadmill time: 3 minutes; metabolic equivalent of task: 1.5 units; floor-to-waist lift: 15 lbs; waist-to-shoulder lift: 10 lbs; 40-foot carry: 10 lbs; and composite score: 6 units. CONCLUSION: This secondary data analysis provides preliminary support for the validity and reliability of the TLC battery for use in military populations.

Enhancing the success of functional restoration using complementary and integrative therapies: Protocol and challenges of a comparative effectiveness study in active duty service members with chronic pain.

Chronic pain significantly impairs physical, psychological and social functioning. Among military populations, pain due to injuries sustained both on and off the battlefield is a leading cause of short and long-term disability. Improving the quality of pain care for active duty service members is a major priority of the Department of Defense. This article describes an ongoing comparative effectiveness study which aims to (1) evaluate the benefit of a multimodal complementary and integrative health (CIH) pain management program when added to standard rehabilitative care (SRC) prior to an intensive functional restoration (FR) program compared to SRC alone, and (2) identify factors that predict improvement in pain impact following treatment completion. Using a randomized controlled trial design, active duty service members with pain related to musculoskeletal injury are assigned to a 3-week course of either SRC or SRC combined with CIH therapies prior to beginning a 3-week course of FR. Outcomes are collected at baseline, at the end of stage 1 treatment, post-FR, and at 3- and 6-months post-FR. Outcome measures include provider-measured functional assessments and patient-reported assessment through the Pain Assessment Screening Tool and Outcomes Registry (PASTOR). The military health system provides a supportive environment for implementation of this research protocol. Challenges to conducting the study have included new technology systems at the study site, slower than projected enrollment, and program delivery issues. These challenges have been successfully managed and have not significantly impacted study participant enrollment and completion of study treatments.

TelePain: Primary Care Chronic Pain Management through Weekly Didactic and Case-based Telementoring.

Chronic pain is a significant problem among military personnel and a priority of the military health system. The U.S. Army Surgeon General's Pain Management Task Force recommends using telehealth capabilities to enhance pain management. This article describes the development and evaluation of a telehealth intervention (TelePain) designed to improve access to pain specialist consultation in the military health system. The study uses a wait-list controlled clinical trial to test: 1) effectiveness of the intervention, and 2) interviews to assess barriers and facilitators of the intervention implementation. The intervention involves a didactic presentation based on the Joint Pain Education Curriculum followed by patient case presentations and multi-disciplinary discussion via videoconference by clinicians working in the military health system. A panel of pain specialists representing pain medicine, internal medicine, anesthesiology, rehabilitation medicine, psychiatry, addiction medicine, health psychology, pharmacology, nursing, and complementary and integrative pain management provide pain management recommendations for each patient case. We use the Pain Assessment Screening Tool and Outcomes Registry (PASTOR) to measure patient outcomes, including pain, sleep, fatigue, anxiety, and depression. This article reports some of the challenges and lessons learned during early implementation of the TelePain intervention. Weekly telephone meetings among the multisite research team were instrumental in problem solving, identifying problem areas, and developing solutions. Solutions for recruitment challenges included additional outreach and networking to military health providers, both building on.

Use of the Pain Assessment Screening Tool and Outcomes Registry in an Army Interdisciplinary Pain Management Center, Lessons Learned and Future Implications of a 10-Month Beta Test.

INTRODUCTION: The U.S. Army Comprehensive Pain Management Campaign Plan was launched in 2010 to improve pain outcomes in military populations. Interdisciplinary Pain Management Centers (IPMCs) were established at every Army medical center, each offering a robust array of treatment options including conventional and complementary and integrative medicine (CIM) pain management therapies. The Pain Assessment Screening Tool and Outcomes Registry (PASTOR) was developed to assess and track biopsychosocial aspects of pain management and to identify best treatment practices. METHODS: During a 10-month pilot test of PASTOR at one Army IPMC, active duty patients completed PASTOR at baseline and at significant junctures during their therapeutic course. RESULTS: 322 IPMC patients completed baseline and follow-up PASTOR assessments. The PASTOR outcomes were analyzed for patients who completed a 3- to 6-week CIM program, a 3-week functional restoration program, or both. For most PASTOR domains, a greater proportion of patients who completed both programs reported important improvement compared with patients who completed either program alone. CONCLUSIONS: This pilot test demonstrated the utility of using PASTOR in a military IPMC to track biopsychosocial treatment outcomes. These preliminary data will inform future comparative effectiveness analyses of pain therapies among military and veteran populations.

Evaluation of the Validity and Response Burden of Patient Self-Report Measures of the Pain Assessment Screening Tool and Outcomes Registry (PASTOR).

BACKGROUND: In 2009, the Army Pain Management Task Force was chartered. On the basis of their findings, the Department of Defense recommended a comprehensive pain management strategy that included development of a standardized pain assessment system that would collect patient-reported outcomes data to inform the patient-provider clinical encounter. The result was the Pain Assessment Screening Tool and Outcomes Registry (PASTOR). The purpose of this study was to assess the validity and response burden of the patient-reported outcome measures in PASTOR. METHODS: Data for analyses were collected from 681 individuals who completed PASTOR at baseline and follow-up as part of their routine clinical care. The survey tool included self-report measures of pain severity and pain interference (measured using the National Institutes of Health Patient-Reported Outcome Measurement Information System [PROMIS] and the Defense and Veterans Pain Rating scale). PROMIS measures of pain correlates also were administered. Validation analyses included estimation of score associations among measures, comparison of scores of known groups, responsiveness, ceiling and floor effects, and response burden. RESULTS: Results of psychometric testing provided substantial evidence for the validity of PASTOR self-report measures in this population. Expected associations among scores largely supported the concurrent validity of the measures. Scores effectively distinguished among respondents on the basis of their self-reported impressions of general health. PROMIS measures were administered using computer adaptive testing and each, on average, required less than 1 minute to administer. Statistical and graphical analyses demonstrated the responsiveness of PASTOR measures over time.
