Active duty military service members (ADSMs) suffer disproportionately from chronic pain. In the USA, military pain physicians serve an important role in the treatment of pain conditions in addition to the maintenance of the fighting force. Expanding roles for pain physicians, including novel therapies, consulting roles for opioid policy, and usefulness in a deployed setting create enormous value for military pain physicians. Ongoing force structure changes, including proposed reduction in the U.S. Military’s healthcare workforce may significantly impact pain care and the health of the fighting forces. Military pain physicians support a variety of different roles in the military healthcare system. Ultimately, maintaining a robust faculty of pain physicians allows for both preservation of the fighting forces and a ready medical force.

Introduction Chronic pain affects over 100 million American adults. The prevalence of chronic pain is even higher among U.S. military personnel. Approximately 44% of active duty military experience pain upon returning from deployment compared with 26% of the general public who experience chronic pain. The high prevalence of chronic pain within the Military Health System is compounded by limited access to chronic pain specialists, specifically with regard to patients at remote military treatment facilities (MTFs). Thus, when compared to personnel at tertiary care MTFs, they often have decreased access to care and experience increased time away from their mission to receive care. Since 2009, Walter Reed National Military Medical Center (WRNMMC) has been using telemedicine to extend chronic pain consults to remote MTFs within the National Capital Region (NCR). The goal of this study was to determine if patients referred to the WRNMMC Telepain Program reported improvements in subjective measures associated with accessing care. To accomplish this, we surveyed a convenience sample of patients using the service to determine if participation: (1) improved pain, (2) improved quality of life, (3) decreased travel time, (4) improved access to care, and (5) decreased time away from work. Materials and Methods An official on behalf of the Institutional Review Board at WRNMMC determined this research to be not human subject research. Over a 13-month period, surveys were administered at the conclusion of all initial Telepain Consults. The survey consisted of an eight question, 5-point balanced Likert scale survey with 1 (strongly disagree) being the most negative and 5 (strongly agree) being most positive. The questions were designed to gauge impact on patient’s perceived access to care, quality of life, overall patient satisfaction, and privacy concerns. The percentages of answers, including strongly agree or agree for positive toned questions and strongly disagree and disagree for negatively toned questions, were calculated and presented in a clustered bar graph. Results A total of 66 Telepain surveys were collected over 13 months with an overall positive reception. Respondents agreed or strongly agreed that Telepain increased access to care (98.5%) and decreased travel time (96.9%). When asked if they would recommend a Telepain visit to others, 93.9% of indicated strongly agree or agree. When asked about overall satisfaction, 83.3% of patients answered completely satisfied or very satisfied. Conclusions The majority of pain specialists within the Military Health System are located at major military medical centers, the most of which are distant from surrounding MTFs. Prior to the development of the WRNMMC Telepain service, personnel at remote MTFs had to endure extended time away from their mission to receive care. The majority of patients that participated in the NCR Telepain program reported a positively perceived impact on pain, access to care, quality of life, transportation burden, and time away from work. In conclusion, The NCR Telepain team of providers have worked together to successfully establish a viable Telepain program at WRNMMC, one that will continue to be further improved and successful in the future.

Description In September 2019, the U.S. Department of Veterans Affairs (VA) and the U.S. Department of Defense (DoD) approved a new joint clinical practice guideline for assessing and managing patients with chronic insomnia disorder and obstructive sleep apnea (OSA). This guideline is intended to give health care teams a framework by which to screen, evaluate, treat, and manage the individual needs and preferences of VA and DoD patients with either of these conditions. Methods In October 2017, the VA/DoD Evidence-Based Practice Work Group initiated a joint VA/DoD guideline development effort that included clinical stakeholders and conformed to the Institute of Medicine's tenets for trustworthy clinical practice guidelines. The guideline panel developed key questions, systematically searched and evaluated the literature, created three 1-page algorithms, and advanced 41 recommendations using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. Recommendations This synopsis summarizes the key recommendations of the guideline in 3 areas: diagnosis and assessment of OSA and chronic insomnia disorder, treatment and management of OSA, and treatment and management of chronic insomnia disorder. Three clinical practice algorithms are also included.

Objective: To demonstrate the prevalence of opioid use disorder (OUD) in the military health system (MHS), geographically map OUD patients and providers, and offer policy recommendations to help increase buprenorphine waiver prescribing. Design: This study was a retrospective review of data from the MHS records. Deidentified records of MHS OUD patients receiving buprenorphine were utilized. Secondary data with nonpersonally identifiable information (PII) were used for pulling records of buprenorphine prescribing providers within the direct care system (MHS providers) and providers from the purchased care system (civilian facilities accepting TRICARE beneficiaries). Setting: This study reviewed records of individuals within the MHS, in the United States, and its territories. Patients and participants: Patients within the MHS system with a diagnosis of OUD. Providers, within the MHS or purchased care, who had prescribed buprenorphine were selected. Main outcome measured: The number of OUD patients in the MHS and providers caring for these OUD patients. In addition, geographical maps illustrating the dispersion of OUD patients, and prescribers were created. Results: The vast majority of MHS OUD patients receive their care from purchase care. Between 2015 and 2018, there has been a shift in the number OUD diagnosed patients by region, and the number of OUD prescribers. Conclusion: The MHS population, particularly active duty, is a transient population. As such, it is not a surprise that the population of OUD patients or prescribers varied by region during that time period. Furthermore, results demonstrate that there is a need to increase the number of buprenorphine-waivered prescribers within the MHS. Changes in policy may encourage more providers to obtain the waiver or increase patient load.

Background The opioid epidemic continues to worsen with a concomitant increase in opioid-related mortality. In response, the Department of Defense and Veterans Health Agency recommended against the use of long-acting opioids (LAOs) and concurrent use of opioids with benzodiazepines. Subsequently, we eliminated benzodiazepines and LAOs from our postoperative pain control regimen. Objective To evaluate the impact of removing benzodiazepines and LAOs on postoperative pain in single-level transforaminal lumbar interbody fusion (TLIF) patients. Methods A retrospective cohort study of single-level TLIF patients from February 2016-March 2018 was performed. Postoperative pain control in the + benzodiazepine cohort included scheduled diazepam with or without LAOs. These medications were replaced with nonbenzodiazepine, opioid-sparing adjuncts in the -benzodiazepine cohort. Pain scores, length of hospitalization, trigger medication use, and opioid use and duration were compared. Results Among 77 patients, there was no difference between inpatient pain scores, but the -benzodiazepine cohort experienced a faster rate of morphine equivalent reduction (-18.7%, 95% CI [-1.22%, -36.10%]), used less trigger medications (-1.55, 95% CI [-0.43, -2.67]), and discharged earlier (0.6 d; 95% CI [0.01, 1.11 d]). As outpatients, the -benzodiazepine cohort was less likely to receive opioid refills at 2 wk (29.2% vs 55.8%, P = .021) and 6 mo postoperatively (0% vs 13.2%, P = .039), and was less likely to be using opioids by 3 mo postoperatively (13.3% vs 34.2%, P = .048). Conclusion Replacement of benzodiazepines and LAOs in the pain control regimen for single-level TLIFs did not affect pain scores and was associated with decreased opioid use, a reduction in trigger medications, and shorter hospitalizations.

Opioid Use Disorder is an international crisis, affecting many populations. Deep learning models can potentially predict opioid use disorder, but provide little insight to how predictions are derived. Impact scores, a new development in explainable artificial intelligence, measure how individual features affect deep learning outcomes. We modeled clinical visits to predict opioid use disorder, computed impact scores, and compared them to odds log ratios from logistic regression. Impact scores were generally comparable to odds log ratios, in providing insight to opioid abuse risk, but from a better-performing method than logistic regression.

The 2016 CDC guidelines and the 2017 Veterans Administration and the Department of Defense (VA/DoD) chronic pain guidelines discouraged the use of chronic opioid therapy for non-cancer, or non-palliative care pain. Both assert that chronic opioid use could cause potential adverse events such as depression, addiction, and death. Both encourage non-opioid interventions such as cognitive behavioral therapy, physical therapy, and various other modalities. To better manage opioid patients with chronic pain, Walter Reed Internal Medicine Department convened a multidisciplinary group composed of pharmacists, physical therapists, psychologists, social workers, internists, and addiction specialists. The group reviewed one patient monthly. Research question: what impact can a multidisciplinary team have on opioid prescribing? STUDY DESIGN: Small cohort study. A clinician performed a chart review of the patients discussed in the multi-disciplinary group. The opioid medications were converted into morphine equivalent daily doses (MEDD) and graphed per patient over time. Although there were 12 patients total, one did not use opioids, and another had not had a follow-up. Among the ten patients left, six had a decrease in their MEDD, three patients’ MEDDs remained the same, one Patient's MEDD increased. The success in lowering 6 of 10 MEDDs is likely multifactorial and based on access to a wide variety of providers and on continuity of care despite being in an institution where turnover is high due to the abundance of military providers. There was a 60% reduction in opioid utilization. In addition, there were unexpected benefits of improved continuity of care, and access to care. Although this a small study, the results demonstrate that a multi-disciplinary approach to managing pain is able to improve healthcare quality, patient safety, and help reduce reliance on opioids. We see opportunities for larger studies as our program matures.

The 2017 Department of Veteran Affairs and Department of Defense (VA/DoD) Opioid Therapy for Chronic Pain Clinical Practice Guidelines (CPGs), represented a paradigm shift in opioid prescribing. The guidelines highlighted the risk of adverse effects, including addiction, overdose, and effects on almost every organ system of the body. The CPGs discouraged against initiation of opioids for chronic use, and advised against exceeding 90 morphine equivalent daily dose (MEDD) for those already on chronic opioid therapy. Research question: will providers reduce their opioid prescribing, if they know that their opioid prescribing exceeds the institutions norms? Quantitative data analysis. The Defense Health Agency (DHA) tracks all military treatment facility providers on a report called the Controlled Substance Prescriber Profile (CSPP) report. A pharmacist used the quarterly CSPP report to identify the top 20 prescribers from Walter Reed, by MED. Letters signed by the Chief of Pharmacy were sent to the prescribers informing them of their MED, along with the institution's average MED. The intervention was repeated quarterly over 2 years. A paired t-test was performed on the quarterly MPA results to see if any changes occurred after the intervention. The paired t-test between 2017 and 2018 resulted in a tStat of 0.897, a p value of 0.217, and a tCritical of 2.353, suggesting there was no difference between the two populations. Comparatively, 2017 compared to 2019 resulted in in a tStat of 4.684, a p value of 0.009, and a tCritical of 2.353; the results of 2017 verses 2019 demonstrate a significant difference. When providers are aware that their prescribing exceeds the institution's norm, they realign their prescribing habits to that of their institution. This study could also be replicated through the prescription drug monitoring program for a group practice, or within a health system.

Description The US Department of Veterans Affairs (VA) and US Department of Defense (DoD) revised the 2010 clinical practice guideline (CPG) for the management of opioid therapy for chronic pain, considering the specific needs of the VA and DoD and new evidence regarding prescribing opioid medication for non-end-of-life-related chronic pain. This paper summarizes the major recommendations and compares them with the US Centers for Disease Control and Prevention (CDC) guideline for prescribing opioids. Patient population This Opioid Therapy CPG was developed for VA-DoD service members, veterans, and their families. Methods The VA/DoD Evidence-Based Practice Work Group convened a VA/DoD guideline renewal development effort and conformed to the guidelines established by the VA/DoD Joint Executive Council (JEC) and VA/DoD Health Executive Council (HEC). The panel developed questions, searched and evaluated the literature, developed recommendations using GRADE methodology, and developed algorithms. Passage of the CARA Act by Congress compelled consideration and comparison with the CDC opioid therapy guideline mid-development. Results There were 18 recommendations made. This article focuses on guideline development and key recommendations with CDC comparisons taken from four major areas, including: initiation and continuation of opioids;type, dose, follow-up, and taper of opioids;risk mitigation;acute pain. Conclusions Guideline development and recommendations are presented. There was substantial overlap with the CDC opioid guideline. Additionally, there were items particularly relevant to the VA-DoD, including risk mitigation, suicide prevention, and preventing opioid use disorder in young patients. Our guideline highlights avoiding opioid therapy longer than 90 days as a critical juncture.

Objectives Chronic pain management typically consists of prescription medications or provider-based, behavioral, or interventional procedures that are often ineffective, may be costly, and can be associated with undesirable side effects. Because chronic pain affects the whole person (body, mind, and spirit), patient-centered complementary and integrative medicine (CIM) therapies that acknowledge the patients' roles in their own healing processes have the potential to provide more efficient and comprehensive chronic pain management. Active self-care CIM therapies (ACT-CIM) allow for a more diverse, patient-centered treatment of complex symptoms, promote self-management, and are relatively safe and cost-effective. To date, there are no systematic reviews examining the full range of ACT-CIM used for chronic pain symptom management. Methods A systematic review was conducted, using Samueli Institute's rapid evidence assessment of the literature (REAL©) methodology, to rigorously assess both the quality of the research on ACT-CIM modalities and the evidence for their efficacy and effectiveness in treating chronic pain symptoms. A working group of subject matter experts was also convened to evaluate the overall literature pool and develop recommendations for the use and implementation of these modalities. Results Following key database searches, 146 randomized controlled trials, covering 33 different pain conditions, were included in the review. Conclusions This article categorized studies by pain condition, describing the diagnostic criteria used and modalities that seem most effective for each condition. Complexities associated with investigating chronic pain populations are also discussed. The entire scope of the review, categorized by modality rather than pain condition, is detailed throughout the current Pain Medicine supplement.

Phantom limb pain is a common consequence of limb amputation and is prevalent among the service members sustaining traumatic battlefield limb injuries during the conflicts in Iraq and Afghanistan. Current treatment to relieve phantom limb pain consists of physical, behavioral, and medical modalities including opioids and adjunct medications. Treatment failure resulting in persistent pain and disability may result. This case series describes four previously healthy service members who developed phantom limb pain following traumatic amputation successfully treated with buprenorphine/naloxone after failing traditional treatment. This is the first reported case series of patients expressing improved pain control with decreased frequency of phantom limb pain with the use of buprenorphine/naloxone instead of traditional opioid agonists.

The most feared drug-induced complication is fatal cardiac arrest. Torsades de pointes (TdP) is a polymorphic ventricular tachycardia occurring in the setting of a QT interval prolongation and is the most frequent type of drug-induced pro-arrhythmia. The most common mechanism of QT prolongation and TdP is blockade of the rapid component of the delayed rectifier repolarizing potassium conductance IKr. Anesthesiologists have extensive experience with QT prolonging drugs, but there are relatively few reports of TdP occurring in the perioperative setting. Nevertheless, regulatory concern regarding the drug droperidol resulted in a significant reduction in its use. Concern regarding two other agents that potently block IKr, i.e., sevoflurane and methadone, has grown, and practitioners are worried that these valuable agents may meet the same fate. In this review, the data regarding the TdP risk of droperidol, sevoflurane, and methadone are compared with particular emphasis on the different settings in which they are employed. While the three drugs are potent IKr inhibitors, little evidence exists to suggest that droperidol or sevoflurane are associated with significant proarrhythmia in the perioperative setting. Due to factors such as inhibition of the parasympathetic nervous system, prevention of hypoxia and hypercarbia, and attention to serum electrolytes, TdP is a very rare occurrence in the perioperative environment. Methadone, however, is typically given to outpatients, over long periods, and in combination with agents that inhibit its metabolism or are QT prolonging in their own right. Thus, pre- and post-drug electrocardiograms may be appropriate when prescribing methadone for outpatients, while the much lower risk for TdP (and the difficulties inherent in QT measurement in the perioperative period) render this approach unfruitful and worthy of reevaluation.

Acute peripheral neuropathic pain after combat-related polytrauma is a common occurrence in the United States military that is often refractory to current drugs and regional anesthesia. Both spinal cord and peripheral nerve stimulation are successfully used for chronic neuropathic pain states, but are not reported for acute neuropathic pain. We present 2 cases of percutaneous ultrasound-guided sciatic peripheral nerve stimulation placement in soldiers who had conditions precluding them from spinal cord stimulation placement. Opioid reduction and marked increase in functionality were possible in one case, and cessation of opioid escalation, with eventual reduction after permanent implantation, was possible in the other.

Combat-related injuries have been well documented for centuries. More recently, injuries suffered by US service members in Iraq and Afghanistan have resulted in a high number of survivable conditions. Polytrauma care in this setting must take into account both the physical and psychological injuries suffered by returning wounded warriors. Catastrophizing may occur when previously healthy individuals are faced with impairment and disfigurement. This is compounded with repeated operative procedures. Early detection and treatment of catastrophizing contributes to improved care of the wounded warrior. This article describes our experiences at Walter Reed Army Medical Center with catastrophizing in US service members returning from the current military operations in Iraq and Afghanistan.

Phantom limb pain (PLP) is believed to be linked to the reorganization of the deafferented sensory cortex. We present a case of a patient with upper extremity PLP who was successfully treated with repetitive transcranial magnetic stimulation (rTMS).We treated an active duty service member who suffered an amputation of his right upper extremity after sustaining a blast injury in Afghanistan. He had 28 sessions of alternating sequences of rTMS to the left dorsolateral prefrontal cortex and primary sensory cortex of the left cerebral hemisphere. Pain intensity was assessed with the Visual Analogue Scale.We delivered 1 Hz stimulation to the sensory cortex corresponding to the area of amputation five times a week. After 4 sessions, the patient's pain decreased from a Visual Analogue Scale of 5 to 2. Left 10 Hz stimulation was added and after 28 sessions, the pain decreased from 2 to 1.Our findings support that rTMS was an effective modality for this patient in treating his PLP. The significance of 10 Hz stimulation is unknown because of the lack of an effect size and is possibly associated with a floor effect.
