Advancing the Pain Agenda in the Veteran Population

Exploring the Experience of Pain and Pain Management for Pregnant and Postpartum Veterans with Chronic Musculoskeletal Pain

BACKGROUND

To examine how veterans experience and treat pain during the perinatal period, we conducted a qualitative study to explore the experiences of pain, pain management, and facilitators and barriers to treatment among perinatal veterans.

METHODS

We identified veterans who received care at any of the 15 Veterans Health Administration (VHA) facilities across the United States and were enrolled in an ongoing cohort study. All participants gave birth to a newborn between March 2016 and June 2021 and met the inclusion criteria for having a prepregnancy pain-related musculoskeletal condition. We completed interviews with 30 veterans between November 2021 and January 2022. We used a framework approach to our qualitative analysis.

RESULTS

Veterans in our sample were, on average, 31 years of age, married (80%), and white (47%). The most common type of pain diagnoses were back pain (93%) and joint disorders (73%). We identified the following major themes: 1) veteran experiences of pain during pregnancy, 2) challenges to pain care during the perinatal period, and 3) veteran recommendations for VHA perinatal pain care. Experiences of pain during pregnancy varied and several barriers to pain care were identified. Veterans suggested several ways the VHA could improve pain care during the perinatal period, including more training for VHA providers on perinatal pain care and greater complementary and integrative health coverage.

CONCLUSIONS

Understanding the unique needs of pregnant veterans with chronic pain is important to provide high-quality care during the perinatal period. Veterans who participated in this study highlighted several areas where the VHA could improve pain management during pregnancy and postpartum.

Mindfulness-Based Therapy for Military Populations with Chronic Pain: A Systematic Review

Background: Due to the limited role of chronic pain medication in military personnel and the distress caused to the military population, mindfulness-based therapy has been considered for the follow-up treatment of military personnel with chronic pain. The purpose of this review is to explore the effect and the implementation of mindfulness-based therapy for the military population with chronic pain. Methods: The keywords for the search included "mindfulness" AND ("pain" OR "chronic pain") AND ("military" OR "veteran"). The PubMed, Embase, and Cochrane Library databases were searched. The Cochrane Collaboration tool was used to independently assess the risk of bias of the included randomized controlled trials, and the Newcastle-Ottawa Scale was used to independently assess the risk of bias of the included case-control studies. Results: A total of 175 papers were identified; 65 duplicates were excluded, and 59 papers that did not meet the inclusion criteria were excluded after reading the titles and abstracts. The remaining 51 papers were read in full, 42 of which did not meet the inclusion criteria. Nine papers met the inclusion criteria and were included in the study. The nine studies included 507 veterans and 56 active-duty female military personnel. All pain interventions were mindfulness-based therapy, and all of them were integrated into or adapted from standard mindfulness courses. The results all showed that after mindfulness-based therapy, the relevant indicators improved. Conclusions: Mindfulness-based therapy is an effective treatment method for the military population with chronic pain. The review indicates that future research should focus on the best setting for mindfulness-based therapy, including the course content and time.

Problem Opioid Use Among US Military Veterans: Prevalence, Correlates, and Psychiatric Characteristics

OBJECTIVE

Problem opioid use (POU) is a serious public health crisis in the United States. However, little research has examined the prevalence, correlates, and psychiatric characteristics of POU in vulnerable segments of the population, such as US military veterans.

METHODS

Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 2441 US veterans. Multivariable logistic regression models were conducted to identify correlates and psychiatric correlates of POU (defined as a positive screen on the Tobacco, Alcohol, Prescription Medication, and Other Substance Use Tool).

RESULTS

A total 3.0% (95% confidence interval, 2.0%-4.5%) of US veterans screened positive for POU. Black, non-Hispanic race/ethnicity (odds ratio [OR], 3.83), lifetime alcohol use disorder (OR, 3.38), major depressive disorder (MDD; OR, 2.52), greater number of medical conditions (OR, 1.15), and disability in instrumental activities of daily living (IADL); OR, 1.86) were independently associated with POU. A significant interaction between IADL disability and MDD was observed (OR, 10.73)-among veterans with IADL disability, those with MDD had more than 6-fold greater POU than those without MDD (20.6% vs 3.2%). Furthermore, POU was associated with 2- to 3-folds greater odds of current generalized anxiety disorder and current posttraumatic stress disorder, and lifetime suicide attempt.

CONCLUSIONS

POU affects 3.0% of US veterans and is associated with Black race/ethnicity, lifetime physical and mental health morbidities, as well as current psychiatric disorders and lifetime suicide attempts. Results underscore the importance of assessing physical and mental health disorders in veterans at-risk for POU and addressing co-occurring psychiatric disorders associated with POU in this population.

Musculoskeletal Pain During Pregnancy Among Veterans: Associations With Health and Health Care Utilization

INTRODUCTION

Musculoskeletal (MSK) pain is more likely to be diagnosed in veterans compared with the general population; however, MSK pain during pregnancy has not been studied in veterans. This study examined health and health care use differences between pregnant veterans with and without MSK pain (MSK-).

METHODS

Veterans who delivered a newborn before June 1, 2021, were identified from an existing cohort (n = 1,181). Survey and Veterans Health Administration (VA) electronic health record data were obtained on participants. Veterans meeting inclusion criteria were identified as those with MSK pain (MSK+) and were compared with MSK- participants. We examined differences between primary outcomes of VA health care engagement (including mental health diagnoses, health care visits, receipt of prescription opioids, and complementary and integrative health use) and secondary outcomes (including postpartum variables) between MSK pain groups. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated.

RESULTS

There were 172 veterans (14.6%) who met MSK pain eligibility criteria. In adjusted models, MSK+ veterans were more likely to be diagnosed with major depressive disorder (aOR, 1.76; 95% CI, 1.22-2.53) and post-traumatic stress disorder (aOR, 1.79; 95% CI, 1.21-2.64) during pregnancy compared with MSK- veterans. The use of VA mental health care (aOR, 1.52; 95% CI, 1.09-2.12) and the odds of receiving an opioid prescription during pregnancy (aOR, 2.76; 95% CI, 1.53-5.00) was higher in MSK+ veterans compared with MSK- veterans. Only a small proportion (3.6%) of our entire cohort used complementary and integrative health approaches during pregnancy. MSK+ veterans were more likely to deliver by cesarean section compared with MSK- veterans (36% vs. 26%).

CONCLUSIONS

MSK+ veterans were more likely to be diagnosed with mental health conditions and to use VA mental health care during pregnancy compared with MSK- veterans. Because veterans receive their obstetrical care in the community, understanding the unique needs of pregnant MSK+ veterans in comparison with MSK- veterans is important to provide comprehensive care during the perinatal period.

Pain: The Silent Public Health Epidemic

More than 50 million Americans suffer from chronic pain, costing our society an estimated 565 to 635 billion dollars annually. Its complexity and training deficits in healthcare providers result in many patients receiving ineffective care. Large health inequities also exist in access to effective pain care for vulnerable populations. The traumatic history of indigenous people and people of color in regards to the experience of pain care perpetuates a lack of trust in the healthcare system, causing many to hesitate to seek medical treatment for painful events and conditions. Other vulnerable populations include those with sickle cell disease or fibromyalgia, whose experience of pain has not been well-understood. There are both barriers to care and stigma for patients with pain, including those taking prescribed doses of long-term opioids, those with known substance use disorder, and those with mental health diagnoses. The suffering of patients with pain can be "invisible" to the clinician, and to one's community at large. Pain can affect all people; but those most vulnerable to not getting effective care may continue to suffer in silence because their voices are not heard. Since 1973, pain societies around the globe have worked tirelessly to bring clinicians together to advance pain and opioid education, research, and patient care. These improvements consist of pain education, integrative treatment, and the understanding that a therapeutic alliance is critical to effective pain management. Pain education for both pre and post-licensure health professionals has increased substantially over the last decade. In addition, integrative and interdisciplinary approaches for clinical pain management are now considered best practices in pain care for patients with moderate to severe pain in addition to the development of a strong therapeutic alliance.

Exploring Perceptions About Paracetamol, Tramadol, and Codeine on Twitter Using Machine Learning: Quantitative and Qualitative Observational Study

BACKGROUND

Paracetamol, codeine, and tramadol are commonly used to manage mild pain, and their availability without prescription or medical consultation raises concerns about potential opioid addiction.

OBJECTIVE

This study aims to explore the perceptions and experiences of Twitter users concerning these drugs.

METHODS

We analyzed the tweets in English or Spanish mentioning paracetamol, tramadol, or codeine posted between January 2019 and December 2020. Out of 152,056 tweets collected, 49,462 were excluded. The content was categorized using a codebook, distinguishing user types (patients, health care professionals, and institutions), and classifying medical content based on efficacy and adverse effects. Scientific accuracy and nonmedical content themes (commercial, economic, solidarity, and trivialization) were also assessed. A total of 1000 tweets for each drug were manually classified to train, test, and validate machine learning classifiers.

RESULTS

Of classifiable tweets, 42,840 mentioned paracetamol and 42,131 mentioned weak opioids (tramadol or codeine). Patients accounted for 73.10% (60,771/83,129) of the tweets, while health care professionals and institutions received the highest like-tweet and tweet-retweet ratios. Medical content distribution significantly differed for each drug (P<.001). Nonmedical content dominated opioid tweets (23,871/32,307, 73.9%), while paracetamol tweets had a higher prevalence of medical content (33,943/50,822, 66.8%). Among medical content tweets, 80.8% (41,080/50,822) mentioned drug efficacy, with only 6.9% (3501/50,822) describing good or sufficient efficacy. Nonmedical content distribution also varied significantly among the different drugs (P<.001).

CONCLUSIONS

Patients seeking relief from pain are highly interested in the effectiveness of drugs rather than potential side effects. Alarming trends include a significant number of tweets trivializing drug use and recreational purposes, along with a lack of awareness regarding side effects. Monitoring conversations related to analgesics on social media is essential due to common illegal web-based sales and purchases without prescriptions.

Effects of hypnosis vs mindfulness meditation vs education on chronic pain intensity and secondary outcomes in veterans: a randomized clinical trial

ABSTRACT

Effective, rigorously evaluated nonpharmacological treatments for chronic pain are needed. This study compared the effectiveness of training in hypnosis (HYP) and mindfulness meditation (MM) with an active education control (ED). Veterans (N = 328) were randomly assigned to 8 manualized, group-based, in-person sessions of HYP (n = 110), MM (n = 108), or ED (n = 110). Primary (average pain intensity [API]) and secondary outcomes were assessed at pretreatment, posttreatment, and 3 and 6 months posttreatment. Treatment effects were evaluated using linear regression, a generalized estimating equation approach, or a Fisher exact test, depending on the variable. There were no significant omnibus between-group differences in pretreatment to posttreatment change in API; however, pretreatment to posttreatment improvements in API and several secondary variables were seen for participants in all 3 conditions. Participation in MM resulted in greater decreases in API and pain interference at 6 months posttreatment relative to ED. Participation in HYP resulted in greater decreases in API, pain interference, and depressive symptoms at 3 and 6 months posttreatment compared with ED. No significant differences on outcomes between HYP and MM were detected at any time point. This study suggests that all 3 interventions provide posttreatment benefits on a range of outcomes, but the benefits of HYP and MM continue beyond the end of treatment, while the improvements associated with ED dissipate over time. Future research is needed to determine whether the between-group differences that emerged posttreatment are reliable, whether there are benefits of combining treatments, and to explore moderating and mediating factors.

Counseling Veterans with Chronic Pain During the COVID-19 Pandemic: A Secondary Analysis of a Randomized Controlled Trial

INTRODUCTION

Veterans with chronic pain could be vulnerable during the COVID-19 pandemic. We qualitatively explored the impact of the COVID-19 pandemic on a sample of veterans receiving brief counseling focused on pain management in an ongoing clinical trial and discuss how the pandemic affected the process of motivating veterans with chronic pain to engage in interdisciplinary multimodal pain treatment at the Department of Veteran Affairs.

METHODS

Segments of audio-recorded counseling sessions containing content about the pandemic were transcribed and coded to identify key concepts emerging from individual counselor-participant transactions. Themes that emerged were examined with constant comparison analysis.

RESULTS

Three major themes emerged. 1) The pandemic caused a disruption in pain management service delivery, resulting in changes to the way veterans receive services or manage their pain symptoms. 2) The pandemic offered opportunities for resilience and personal growth as veterans with chronic pain reflected on their lives and personal goals. 3) The pandemic brought veterans' mental health issues to the forefront, and these should be addressed as part of a comprehensive pain management approach.

DISCUSSION

Discussion of the COVID-19 pandemic during pain treatment counseling sessions highlighted negative and positive ways participants were affected by the pandemic. These discussions provided counselors with a unique opportunity to facilitate behavior change by focusing on characteristics of resilience to motivate individuals with chronic pain to adapt and adopt positive behaviors and outlooks to improve their pain experience and quality of life.

CONCLUSIONS

Counselors can leverage feelings of resilience and personal growth to motivate veterans' use of adaptive coping skills and a wider array of pain management services.

Patient demographics and clinical characteristics influence opioid and nonopioid pain management prescriptions of primary care NPs, PAs, and physicians

BACKGROUND

Evidence exists on racial and gender disparities in chronic pain management among veterans. Most literature has described physicians' disparate opioid prescribing patterns, although it is unknown if prescribing disparities exist among nurse practitioners (NPs) and physician assistants (PAs) or among prescription of nonopioid analgesic strategies.

PURPOSE

To identify patient characteristics associated with opioid and nonopioid prescriptions among Veterans Affairs (VA) chronic pain patients by primary care physicians, NPs, and PAs.

METHODOLOGY

We used data from the VA's Survey of Health care Experience of Patients and Corporate Data Warehouse from October 2015 to September 2016. Outcomes included opioid and nonopioid analgesic prescriptions. Patient characteristics included race/ethnicity, gender, education level, age, and clinical characteristics (comorbidities, self-reported health, and self-reported mental health). Logistic regression was performed to test for associations of patient characteristics with outcomes.

RESULTS

Patients who were White, male, age 41-64 years, and with no postsecondary education had higher odds of receiving an opioid prescription (all p -values ≤ .01), whereas patients who were Black, female, and <65 years old had higher odds of a nonopioid prescription (all p -values < .01). Having 5+ comorbidities and fair/poor self-reported health increased the odds of opioid and nonopioid prescriptions (all p -values < .01).

CONCLUSIONS

Disparities in race, gender, and educational level significantly affect how primary care NPs, PAs, and physicians manage chronic pain.

IMPLICATIONS

NPs and other primary care providers should pursue training opportunities to identify and mitigate potential biases that may affect their practice. Future research should take an intersectional lens in examining the source of chronic pain disparities.

Influence of Primary Care Provider Type on Chronic Pain Management Among Veterans

Background

Chronic pain disproportionately impacts veterans and is often treated in primary care, where physician shortages in the Veterans Health Administration (VHA) healthcare system are well documented. Nurse practitioners (NPs) may represent a solution to the care shortage; however, concerns of NP opioid overprescribing have led to NP practice and prescribing restrictions in individual VHA facilities and at the state level. Little is known regarding the prescribing patterns of NPs and physician assistants (PAs) for veterans with chronic pain in the VHA.

Purpose

The purpose of this study was to compare opioid and non-opioid prescribing patterns of physicians, NPs, and PAs for chronic pain patients at VHA centers.

Methods

We used data from the U.S. Department of Veterans Affairs Survey of Healthcare Experience of Patients and Corporate Data Warehouse from October 2015 to September 2016. Patient medical records for the year were analyzed by provider type (physician, NP, or PA) for differences in providers' rates of prescribing opioid and non-opioid medications, as well as characteristics of the opioid prescriptions (e.g., high daily morphine milligram equivalent [90 MME/day] dose, long-term opioid therapy [90 days]).

Results

Medical records of a total of 39,936 patients were included. In FY 2016, 55% of patients received one opioid prescription, whereas 83.8% received one non-opioid prescription. Compared to patients of NPs and PAs, patients of physicians had higher odds of receiving opioid (vs. NPs: OR = 1.13, p < 0.01; vs. PAs: OR = 1.16, p < 0.01) and non-opioid prescriptions (vs. NPs: OR=1.08, p = 0.02; vs. PAs: OR=1.20, p < 0.01) after adjusting for patient characteristics. There were no differences in high MME/day dose (p = 0.59) or long-term opioid therapy (p = 0.99).

Conclusion

In a national sample of veterans with chronic pain, NPs and PAs did not have higher odds of opioid prescribing. Concerns of NP or PA opioid overprescribing may be addressed by considering evidence that patients of these providers are not at higher odds of receiving an opioid prescription.

Drug-drug-gene interaction risk among opioid users in the U.S. Department of Veterans Affairs

ABSTRACT

Response to analgesic therapy is influenced by several factors including genetics and drug-drug interactions. Pharmacogenetic (PGx) variants in the CYP2D6 gene modify response to opioids by altering drug metabolism. We sought to determine the potential impact of PGx testing on the care of Veterans with noncancer pain prescribed opioids metabolized by CYP2D6 (codeine, hydrocodone, or tramadol). A retrospective analysis was performed within the Veterans Health Administration (VHA) evaluating prescription records for pain medications metabolized by CYP2D6 and interacting drugs from 2012-2017. Among 2,436,654 VHA pharmacy users with at least one opioid prescription, 34% met the definition of chronic use (longer than 90 days with more than 10 prescriptions or 120 days- supply). Opioids were commonly co-prescribed with antidepressants interacting with CYP2D6 (28%). An estimated 21.6% (n=526,905) of these patients are at elevated risk of an undesirable response to their opioid medication based on predicted phenotypes and drug-drug interactions: 3.5% are predicted CYP2D6 ultrarapid metabolizers and at increased risk for toxicity, 5.4% are poor metabolizer at higher risk for nonresponse, and 12.8% are normal or intermediate metabolizers co-prescribed a CYP2D6 inhibitor leading to phenoconversion into poor metabolizer. Despite the high rate of co-prescription of opioids and interacting drugs, CYP2D6 testing was infrequent in the sample (0.02%) and chart review suggest that test results were used to optimize antidepressant treatments rather than pain medications. Using pharmacogenetic testing combined with consideration of phenoconversion may allow for an enhanced precision medicine approach to pain management in Veterans.

Pudendal nerve block prior to inflatable penile prosthesis implantation: decreased intra-operative narcotic requirements

The opioid epidemic has proven to be a public health crisis over the past two decades and efforts to decrease opioid exposure are sorely needed. Our objective was to determine whether pudendal nerve block utilization in the immediate pre-operative setting decreases intra-operative opioid analgesic requirements in veteran patients undergoing a primary inflatable penile prosthesis implantation. We performed a retrospective cohort analysis of all patients undergoing penile prosthesis implantation between January 2017 and July 2020 at the Charlie Norwood Veterans Affairs Medical Center in Augusta, GA. Univariable and multivariable gamma regression analyses were performed to evaluate the association between pudendal nerve block utilization and intra-operative opioid analgesic requirements. The study cohort consisted of 110 patients, 35 (31.8%) of whom underwent a pudendal nerve block. Median intra-operative opioid analgesic requirements were significantly lower in the pudendal nerve block group (16.3 versus 25.8 morphine milliequivalents, p = 0.037). Receipt of the nerve block was associated with significantly lower intra-operative opioid analgesic requirements on multivariable (coefficient 0.84, p = 0.038) regression analysis. There was no significant difference in post-operative opioid analgesic requirements (p = 0.18). In conclusion, pre-operative pudendal nerve blocks decrease intra-operative opioid analgesic requirements in veteran patients undergoing a primary inflatable penile prosthesis implantation.

High-Dose Opioid Use Among Veterans with Unexplained Gastrointestinal Symptoms Versus Structural Gastrointestinal Diagnoses

BACKGROUND

In a cohort of Veterans dually enrolled in the Department of Veterans Affairs (VA) and Medicare Part D, we sought to describe high-dose daily opioid use among Veterans with unexplained gastrointestinal (GI) symptoms and structural GI diagnoses and examine factors associated with high-dose use.

METHODS

We used linked national patient-level data from the VA and Centers for Medicare and Medicaid Services (CMS). We grouped patients into 3 subsets: those with unexplained GI symptoms (e.g., chronic abdominal pain); structural GI diagnoses (e.g., chronic pancreatitis); and those with a concurrent unexplained GI symptom and structural GI diagnosis. High-dose daily opioid use levels were examined as a binary variable [≥ 100 morphine milligram equivalents (MME)/day] and as an ordinal variable (50-99 MME/day, 100-119 MME/day, or ≥ 120 MME/day).

RESULTS

We identified 141,805 chronic GI patients dually enrolled in VA and Part D. High-dose opioid use was present in 11% of Veterans with unexplained GI symptoms, 10% of Veterans with structural GI diagnoses, and 15% of Veterans in the concurrent GI group. Compared to Veterans with only an unexplained GI symptom or structural diagnosis, concurrent GI patients were more likely to have higher daily opioid doses, more opioid days ≥ 100 MME, and higher risk of chronic use. Factors associated with high-dose use included opioid receipt from both VA and Part D, younger age, and benzodiazepine use.

CONCLUSIONS

A significant subset of chronic GI patients in the VA are high-dose opioid users. Efforts are needed to reduce high-dose use among Veterans with concurrent GI symptoms and diagnoses.

Differential Pain Presentations Observed Across Post-Traumatic Stress Disorder Symptom Trajectories After Combat Injury

OBJECTIVE

This study evaluated the association between pain outcomes and post-traumatic stress disorder (PTSD) symptom trajectories after combat-related injury, while adjusting for receipt of regional anesthesia (RA) soon after injury.

METHODS

The PTSD symptom trajectories of N = 288 combat-injured service members were examined from within a month of injury up to two-years after. Linear mixed-effects models evaluated the association between PTSD symptom trajectories and average pain and pain interference outcomes while adjusting for receipt of RA during combat casualty care.

RESULTS

Four PTSD trajectories were characterized: resilient, recovering, worsening, and chronic. Differential pain presentations were associated with PTSD symptom trajectories, even after adjusting for receipt of RA. Compared to those with a resilient PTSD symptom trajectory, individuals presenting with chronic PTSD trajectories were estimated to experience average pain scores 2.61 points higher (95% CI: 1.71, 3.14). Participants presenting with worsening (β = 1.42; 95% CI: 0.77, 1.78) and recovering PTSD trajectories (β = 0.65; 95% CI: 0.09, 1.08) were estimated to experience higher average pain scores than participants with resilient PTSD trajectories. Significant differences in pain interference scores were observed across PTSD trajectories. Receiving RA was associated with improved pain up to two years after injury (β =-0.31; 95% CI: -0.90, -0.04), however no statistically significant association was detected between RA and PTSD trajectories.

CONCLUSIONS

PTSD trajectories were associated with greater pain intensity and interference following combat injury even when accounting for receipt of early RA for pain management. These findings underscore the need to jointly assess pain and PTSD symptoms across the trauma care continuum.

Telehealth and rural-urban differences in receipt of pain care in the Veterans Health Administration

OBJECTIVE

Examine changes in specialty pain utilization in the Veterans Health Administration (VHA) after establishing a virtual interdisciplinary pain team (TelePain).

DESIGN

Retrospective cohort study.

SETTING

A single VHA healthcare system, 2015-2019.

SUBJECTS

33,169 patients with chronic pain-related diagnoses.

METHODS

We measured specialty pain utilization (in-person and telehealth) among patients with moderate to severe chronic pain. We used generalized estimating equations to test the association of time (pre- or post-TelePain) and rurality on receipt of specialty pain care.

RESULTS

Among patients with moderate to severe chronic pain, the reach of specialty pain care increased from 11.1% to 16.2% in the pre- to post-TelePain periods (aOR: 1.37, 95% CI: 1.26-1.49). This was true of both urban patients (aOR: 1.62, 95% CI: 1.53-1.71) and rural patients (aOR: 1.16, 95% CI: 0.99-1.36), although the difference for rural patients was not statistically significant. Among rural patients who received specialty pain care, a high percentage of the visits were delivered by telehealth (nearly 12% in the post-TelePain period), much higher than among urban patients (3%).

CONCLUSIONS

We observed increased use of specialty pain services among all patients with chronic pain. Although rural patients did not achieve the same degree of access and utilization overall as urban patients, their use of pain telehealth increased substantially and may have substituted for in-person visits. Targeted implementation efforts may be needed to further increase the reach of services to patients living in areas with limited specialty pain care options.

Perspectives of patients with chronic pain about a pain science education video

Purpose: Patients have responded in variable ways to pain science education about the psychosocial correlates of pain. To improve the effectiveness of pain education approaches, this study qualitatively explored participants' perceptions of and responses to pain science education.Methods: We conducted a qualitative content analysis of interviews with fifteen, adult patients (73.3% female) who had recently attended a first visit to a chronic pain clinic and watched a pain science educational video.Results: Participants thought it was important to improve their and healthcare providers' understanding of their pain. They viewed the video favorably, learned information from it, and thought it could feasibly facilitate communication with their healthcare providers, but, for many participants, the video either did not answer their questions and/or raised more questions. Participants' responses to the video included negative and positive emotions and were influenced by their need for confirmation that their pain was real and personal relevance of the pain science content.Conclusion: Study results support the feasibility and value of delivering pain science education via video and increase our understanding of patients' perceptions of and responses to pain science education. The video's triggering of emotional responses warrants additional research.

Chronic pain: an update on burden, best practices, and new advances

Chronic pain exerts an enormous personal and economic burden, affecting more than 30% of people worldwide according to some studies. Unlike acute pain, which carries survival value, chronic pain might be best considered to be a disease, with treatment (eg, to be active despite the pain) and psychological (eg, pain acceptance and optimism as goals) implications. Pain can be categorised as nociceptive (from tissue injury), neuropathic (from nerve injury), or nociplastic (from a sensitised nervous system), all of which affect work-up and treatment decisions at every level; however, in practice there is considerable overlap in the different types of pain mechanisms within and between patients, so many experts consider pain classification as a continuum. The biopsychosocial model of pain presents physical symptoms as the denouement of a dynamic interaction between biological, psychological, and social factors. Although it is widely known that pain can cause psychological distress and sleep problems, many medical practitioners do not realise that these associations are bidirectional. While predisposing factors and consequences of chronic pain are well known, the flipside is that factors promoting resilience, such as emotional support systems and good health, can promote healing and reduce pain chronification. Quality of life indicators and neuroplastic changes might also be reversible with adequate pain management. Clinical trials and guidelines typically recommend a personalised multimodal, interdisciplinary treatment approach, which might include pharmacotherapy, psychotherapy, integrative treatments, and invasive procedures.

Flipping the Pain Care Model: A Sociopsychobiological Approach to High-Value Chronic Pain Care

OBJECTIVE

Much of the pain care in the United States is costly and associated with limited benefits and significant harms, representing a crisis of value. We explore the current factors that lead to low-value pain care within the United States and provide an alternate model for pain care, as well as an implementation example for this model that is expected to produce high-value pain care.

METHODS

From the perspective of aiming for high-value care (defined as care that maximizes clinical benefit while minimizing harm and cost), we describe the current evidence practice gap (EPG) for pain care in the United States, which has developed as current clinical care diverges from existing evidence. A discussion of the biomedical, biopsychosocial, and sociopsychobiological (SPB) models of pain care is used to elucidate the origins of the current EPG and the unconscious factors that perpetuate pain care systems despite poor results.

RESULTS

An interprofessional pain team within the Veterans Health Administration is described as an example of a pain care system that has been designed to deliver high-value pain care and close the EPG by implementing the SPB model.

CONCLUSIONS

Adopting and implementing a sociopsychobiological model may be an effective approach to address the current evidence practice gap and deliver high-value pain care in the United States. The Phoenix VA Health Care System's Chronic Pain Wellness Center may serve as a template for providing high-value, evidence-based pain care for patients with high-impact chronic pain who also have medical, mental health, and opioid use disorder comorbidities.

Adapting Mindfulness Training for Military Service Members With Chronic Pain

INTRODUCTION

Rates of chronic pain in military personnel are disproportionately high. Chronic pain is often associated with mental health and substance use disorders as comorbid conditions, making treatment of chronic pain complex. Mindfulness-based interventions (MBIs) are a promising behavioral approach to managing chronic pain and psychosocial sequelae. The unique nature of the military context may require adaptations to original MBIs for successful delivery in active-duty military populations. This study adapted the mindfulness-based stress reduction (MBSR) program to create a mindfulness training program that was relevant to active-duty Army personnel experiencing chronic pain. This article delineates the adaptation process employed to modify the MBSR program to the military context and discusses the resulting training program.

MATERIALS AND METHODS

The adaptation process consisted of three iterative stages: 1) Drafting the preliminary intervention protocol with recommendations from stakeholders, including military healthcare providers; 2) Refining the preliminary protocol after pretesting the sessions with research team members and a military Veteran advisory committee; and 3) Delivering the preliminary protocol to one cohort of active-duty Soldiers with chronic pain, collecting feedback, and further refining the intervention protocol.

RESULTS

Military-related adaptations to MBSR addressed three areas: military culture, language and terminology, and practical and logistical factors relevant to implementation in the military setting. This adaptation process resulted in a live, online program with six, weekly, sessions. Feedback from a military Veteran advisory committee resulted in modifications, including increasing military-relevant examples; preliminary testing with the target population resulted in additional modifications, including shortening the sessions to 75 min and structuring discussions more efficiently.

CONCLUSIONS

The adaptation process was successful in generating an engaging mindfulness training program that was highly relevant to the military context. Obtaining input from stakeholders, such as military healthcare providers and active-duty soldiers, and iterative feedback and modification, were key to the process. Moreover, the program was designed to maintain the integrity and core elements of MBIs while adapting to military culture. A future randomized controlled trial design will be used to evaluate the effectiveness of the intervention in improving chronic pain in military personnel. This program is responsive to the military's call for nonpharmacologic treatments for chronic pain that are easily accessible. If effective, the mindfulness program has the potential for widespread dissemination to complement standard care for Service Members experiencing chronic pain.

Mobile Neurofeedback for Pain Management in Veterans with TBI and PTSD

OBJECTIVE

Chronic pain is common in military veterans with traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD). Neurofeedback, or electroencephalograph (EEG) biofeedback, has been associated with lower pain but requires frequent travel to a clinic. The current study examined feasibility and explored effectiveness of neurofeedback delivered with a portable EEG headset linked to an application on a mobile device.

DESIGN

Open-label, single-arm clinical trial.

SETTING

Home, outside of clinic.

SUBJECTS

N = 41 veterans with chronic pain, TBI, and PTSD.

METHOD

Veterans were instructed to perform "mobile neurofeedback" on their own for three months. Clinical research staff conducted two home visits and two phone calls to provide technical assistance and troubleshoot difficulties.

RESULTS

N = 36 veterans returned for follow-up at three months (88% retention). During this time, subjects completed a mean of 33.09 neurofeedback sessions (10 minutes each). Analyses revealed that veterans reported lower pain intensity, pain interference, depression, PTSD symptoms, anger, sleep disturbance, and suicidal ideation after the three-month intervention compared with baseline. Comparing pain ratings before and after individual neurofeedback sessions, veterans reported reduced pain intensity 67% of the time immediately following mobile neurofeedback. There were no serious adverse events reported.

CONCLUSIONS

This preliminary study found that veterans with chronic pain, TBI, and PTSD were able to use neurofeedback with mobile devices independently after modest training and support. While a double-blind randomized controlled trial is needed for confirmation, the results show promise of a portable, technology-based neuromodulatory approach for pain management with minimal side effects.

The Resurrection of Interdisciplinary Pain Rehabilitation: Outcomes Across a Veterans Affairs Collaborative

OBJECTIVE

Despite empirical support for interdisciplinary pain rehabilitation programs improving functioning and quality of life, access to this treatment approach has decreased dramatically over the last 20 years within the United States but has grown significantly in the Department of Veterans Affairs (VA). Between 2009 and 2019, VA pain rehabilitation programs accredited by the Commission on Accreditation of Rehabilitation Facilities increased 10-fold in the VA, expanding from two to 20. The aim of this collaborative observational evaluation was to examine patient outcomes across a subset of six programs at five sites.

METHODS

Outcomes were assessed using agreed-upon measures of patient-reported pain intensity, pain interference across various domains, pain catastrophizing, and sleep.

RESULTS

A total of 931 patients enrolled in the selected VA interdisciplinary pain programs, with 84.1% of participants completing the full course of treatment. Overall, all programs showed significant improvements from pretreatment to posttreatment in nearly all patient-reported outcomes. The effect sizes ranged from medium to large. Notably, the results demonstrate that positive outcomes were typical despite differences in structure and resources across programs.

CONCLUSIONS

The adverse impacts of opioid use have highlighted the importance of chronic pain treatment approaches that emphasize team-based care focused on functional improvements. This study represents the first and largest analysis of outcomes across chronic pain rehabilitation programs and demonstrates the need for increased access to similar comprehensive approaches to pain management across the health care system. Further, it suggests that a variety of structures may be effective, encouraging flexibility in adopting this interdisciplinary approach.

Remote introductory pharmacy practice experiences focused on veterans prescribed chronic opioid therapy

PURPOSE

The Department of Veterans Affairs (VA) Northern California Health Care System (NCHCS) uses a dashboard to identify monitoring needs for veterans prescribed chronic opioid therapy (COT). Schools of pharmacy require introductory pharmacy practice experiences (IPPEs); however, resources for providing IPPEs at medical facilities are limited. This article describes collaboration by a primary care service and a school of pharmacy to provide services for patients prescribed COT through remote access to the VA electronic health record (EHR) system.

SUMMARY

Pharmacy students in a required population health IPPE provided clinical services for veterans remotely. Students were supervised by VA clinical pharmacists and granted remote EHR access privileges. Using personally owned laptops and VA cell phones, students performed prescription drug monitoring program (PDMP) activities, reviewed urine drug screening (UDS) results, called patients to assess pain, and documented progress notes. Students completed an assessment on the first and final days of the experience; a retrospective analysis was conducted to examine differences in student knowledge of and confidence in providing COT-focused services. The dashboard scorecard and student workload were tracked over a 1-year period. In that year, 143 students wrote 7,001 PDMP notes, reviewed 6,130 UDS results, and documented 202 pain assessments. Statistically significant improvements were reported in students' level of confidence in performing population health activities for patients prescribed COT, including interpreting PDMP and UDS results and talking with patients.

CONCLUSION

The ongoing collaboration provides real-world population management experiences for future pharmacists and supports monitoring requirements for veterans prescribed COT. The program has helped NCHCS accomplish its teaching mission without dedicating clinic workspace or computers and gain an additional team to address quality measures and support population health activities.

Predictors of Prolonged Opioid Use After Initial Prescription for Acute Musculoskeletal Injuries in Adults : A Systematic Review and Meta-analysis of Observational Studies

BACKGROUND

Opioids are frequently prescribed for acute musculoskeletal injuries and may result in long-term use and consequent harms.

PURPOSE

To explore factors associated with persistent opioid use after its prescription for acute musculoskeletal injury.

DATA SOURCES

Searches of multiple electronic databases, without language restrictions, from inception to 6 January 2020, and reference lists of selected articles.

STUDY SELECTION

Observational studies of adults with opioid prescriptions for outpatient acute musculoskeletal injuries, in an adjusted model, that explored risk factors for prolonged use.

DATA EXTRACTION

6 reviewers, working in pairs, independently extracted data, rated the quality of studies, and evaluated the certainty of evidence.

DATA SYNTHESIS

14 cohorts with 13 263 393 participants were included. The overall prevalence of prolonged opioid use after musculoskeletal injury for high-risk populations (that is, patients receiving workers' compensation benefits, Veterans Affairs claimants, or patients with high rates of concurrent substance use disorder) was 27% (95% CI, 18% to 37%). The prevalence among low-risk populations was 6% (CI, 4% to 8%; P for interaction < 0.001). Moderate-certainty evidence showed increased odds of persistent opioid use with older age (absolute risk increase [ARI] for every 10-year increase, 1.1% [CI, 0.7% to 1.5%]) and physical comorbidity (ARI, 0.9% [CI, 0.1% to 1.7%]). Low-certainty evidence suggested increased risk for persistent opioid use with past or current substance use disorder (ARI, 10.5% [CI, 4.2% to 19.8%]), prescriptions lasting more than 7 days (median ARI, 4.5%), and higher morphine milligram equivalents per day.

LIMITATION

Sparse, heterogeneous data with suboptimal adjustment for potential confounders.

CONCLUSION

Avoiding prescribing opioids for acute musculoskeletal injuries to patients with past or current substance use disorder, and restricting duration to 7 days or less and using lower doses when they are prescribed, are potentially important targets to reduce rates of persistent opioid use.

Drug Overdose and Suicide Among Veteran Enrollees in the VHA: Comparison Among Local, Regional, and National Data

Background

Suicide is the 10th leading cause of death in the US, primarily from drug overdose. In 2017, 67.8% of drug overdoses were with prescription opioids. The rate of opioid use disorder among patients in the Veterans Health Administration (VHA) is 7 times higher than that of non-VHA enrollees. This study compares the incidence of overdose and suicide across facility, regional, and national levels in the VHA system in the context of a multispecialty opioid risk reduction program at the North Florida/South Georgia Veteran Health System (NF/SGVHS).

Methods

This retrospective study used fiscal years 2012 to 2016 overdose and suicide aggregate data from the US Department of Veterans Affairs (VA) Support Service Center medical diagnosis cube and VA Suicide Prevention Program. Overdose data were aggregated by facility and fiscal year, and overdose rates (per 1,000 individuals) were calculated.

Results

The average annual rate of overdose diagnosis at NF/SGVHS during the study period was slightly higher (16.8 per 1,000) compared with its region (16.0 per 1,000), and VHA national (15.3 per 1,000) rates. The NF/SGVHS had the lowest average annual rate of suicide (9.1 per 100,000) during the study period, which was one-quarter of the VHA national rate.

Conclusions

NF/SGVHS developed and implemented a biopsychosocial model of pain treatment that includes primary care integrated with mental health and addiction services. The presence of this program during a period when the facility was tapering opioid prescriptions could explain the relative reduced suicide rate.

Examining the Effect of a Whole Health Primary Care Pain Education and Opioid Monitoring Program on Implementation of VA/DoD-Recommended Guidelines for Long-term Opioid Therapy in a Primary Care Chronic Pain Population

OBJECTIVE

To describe the core elements of a Whole Health Primary Care Pain Education and Opioid Monitoring Program (PC-POP) and examine its effectiveness at increasing adherence to six of the Veteran Affairs/Department of Defense (VA/DoD) recommended guidelines for long-term opioid therapy (LOT) among chronic noncancer patients seen in primary care (i.e., urine drug screens [UDS], prescription drug monitoring program [PDMP] queries, informed consent, naloxone education/prescriptions, morphine equivalent daily dose [MEDD], and referrals to nonpharmacological pain interventions).

DESIGN/METHODS

A within-subjects comparison of outcomes was conducted between pre- and post-PC-POP enrollees (N = 25), as was a a between-subjects comparison to a comparison group (N = 25) utilizing a six-month range post-index date of 10/1/2018 (i.e., between-subjects comparison at Time 2).

SUBJECTS

A convenience sample of adult veterans with chronic noncancer pain receiving opioid therapy consecutively for the past three months in primary care.

RESULTS

Results showed increased concordance with VA/DoD guidelines among those enrolled in the PC-POP, characterized by increased documentation of urine drug screens, prescription drug monitoring program queries, informed consent, naloxone education/prescriptions, and a decrease in MEDD among patients enrolled in the PC-POP.

CONCLUSIONS

The PC-POP shows promise for increasing guideline-concordant care for providers working in primary care.

A Brief Report on an 8-Week Course of Mindfulness-based Care for Chronic Pain in the Treatment of Veterans With Back Pain: Barriers Encountered to Treatment Engagement and Lessons Learned

BACKGROUND

Chronic pain and associated symptoms are debilitating for veterans. Medical costs of treatments are high and current treatment options, most notably with opioid medications, have been associated with significant risk. Mindfulness-based interventions appear promising for chronic pain, but require additional testing in veteran care settings.

OBJECTIVE

This project was designed to test the feasibility of engaging and retaining veterans with chronic lower back pain in a new mindfulness protocol tailored for veterans, mindfulness-based care for chronic pain (MBCP). Clinical outcomes were also assessed.

DESIGN

An open pilot trial of an 8-week MBCP course that included meditation, gentle yoga, and psychoeducation.

SUBJECTS

Twenty-two veterans (mean age=49.77; 18% women) were recruited from a VA Medical Center in the Northeastern US. After screening for inclusion/exclusion criteria, 20 were eligible at baseline.

MEASURES

Veterans were assessed at baseline and postintervention for functional impairment, pain intensity and bothersomeness, depression, and mindfulness.

RESULTS

The average number of sessions completed was 5; only 4 (20%) attended all sessions. Eleven of the 20 participants (55%) attended 5 or more sessions and had complete preintervention and postintervention visits. Five of the 11 had a clinically meaningful decrease in pain intensity and in depressive symptoms, while 6 of 11 had a meaningful decrease in pain bothersomeness and functional impairment.

CONCLUSIONS

It was challenging to enroll and retain participants in this study, even with our intervention designed for veterans. We discuss possible adaptations and refinements in MBCP for veterans with chronic pain to enhance feasibility and improve upon these interventions.

Pain Intensity and Pain Interference in Male and Female Iraq/Afghanistan-era Veterans

BACKGROUND

Chronic pain conditions are common among both male and female Iraq/Afghanistan-era veterans and can have substantial negative impacts on quality of life and function. Although in general women tend to report higher levels of pain intensity than men, findings remain mixed on whether gender differences in pain exist in Iraq/Afghanistan-era veterans. Additionally, the relationships between functional impairment, pain intensity, and gender remain unknown.

METHODS

This project examined gender differences in pain intensity and pain interference in 875 male and female Iraq/Afghanistan-era veterans. Nonparametric Wilcoxon rank-tests examined gender differences in pain scores. Multivariable generalized linear regression modeling was used to evaluate the magnitude of pain intensity and interference across levels of chronicity and gender, and to evaluate the role of chronicity in gender effects in measures of pain and function.

RESULTS

Pain intensity and interference scores were significantly greater among both male and female veterans reporting chronic pain relative to acute pain. Women veterans endorsed higher levels of pain intensity and pain interference compared with men. Results derived from multivariable analyses implicated pain intensity as a factor underlying gender differences in functional impairment among chronic pain sufferers, indicating that gender differences in functional measures were eliminated after controlling statistically for pain intensity.

CONCLUSIONS

Results demonstrate that the effects of functional impairment are impacted by pain intensity, and not by gender.

Scope and Nature of Pain- and Analgesia-Related Content of the United States Medical Licensing Examination (USMLE)

Background

"The ongoing opioid crisis lies at the intersection of two substantial public health challenges-reducing the burden of suffering from pain and containing the rising toll of the harms that can result from the use of opioid medications" [1]. Improved pain education for health care providers is an essential component of the multidimensional response to both still-unmet challenges [2,3]. Despite the importance of licensing examinations in assuring competency in health care providers, there has been no prior appraisal of pain and related content within the United States Medical Licensing Examination (USMLE).

Methods

An expert panel developed a novel methodology for characterizing USMLE questions based on pain core competencies and topical and public health relevance.

Results

Under secure conditions, raters used this methodology to score 1,506 questions, with 28.7% (432) identified as including the word "pain." Of these, 232 questions (15.4% of the 1,506 USMLE questions reviewed) were assessed as being fully or partially related to pain, rather than just mentioning pain but not testing knowledge of its mechanisms and their implications for treatment. The large majority of questions related to pain (88%) focused on assessment rather than safe and effective pain management, or the context of pain.

Conclusions

This emphasis on assessment misses other important aspects of safe and effective pain management, including those specific to opioid safety. Our findings inform ways to improve the long-term education of our medical and other graduates, thereby improving the health care of the populations they serve.

The Socioeconomic Burden of Pain From War

War's burden on the health and well-being of combatants, civilians, and societies is well documented. Although the examination of soldiers' injuries in modern combat is both detailed and comprehensive, less is known about war-related injuries to civilians and refugees, including victims of torture. The societal burden of war-related disabilities persists for decades in war's aftermath. The complex injuries of combat survivors, including multiple pain conditions and neuropsychiatric comorbidities, challenge health care systems to reorganize care to meet these survivors' special needs.We use the case study method to illustrate the change in pain management strategies for injured combat survivors in one national health system, the US Department of Veterans Affairs (VA). The care of veterans' disabling injuries suffered in Vietnam contrasts with the care resulting from the VA's congressional mandate to design and implement a pain management policy that provides effective pain management to veterans injured in the recent Middle East conflicts.The outcomes-driven, patient-centric Stepped Care Model of biopsychosocial pain management requires system-wide patient education, clinician training, social networking, and administrative monitoring. Societies are encouraged to develop their health care system's capacity to effectively respond to the victims of warfare, including combatants and refugees.

Adaption of the Biopsychosocial Model of Chronic Noncancer Pain in Veterans

Population

Veterans with chronic noncancer pain (CNCP) are a vulnerable population whose care remains a challenge for clinicians, policy-makers, and researchers. As a result of military experience, veterans are exposed to high rates of musculoskeletal injuries, trauma, psychological stressors (e.g., post-traumatic stress disorder, depression, anxiety, substance abuse), and social factors (e.g., homelessness, social isolation, disability, decreased access to medical care) that contribute to the magnitude and impact of CNCP. In the veteran population, sound theoretical models are needed to understand the specific physiological, psychological, and social factors that influence this unique experience.

Objective

This paper describes an adaption of Gatchel and colleagues' biopsychosocial model of CNCP to veterans and summarizes research findings that support each component of the revised model. The paper concludes with a discussion of important implications for the use of this revised model in clinical practice and future directions for research.

Conclusions

The adaption of the biopsychosocial model of CNCP for veterans provides a useful and relevant conceptual framework that can be used to guide future research and improve clinical care in this vulnerable population.

Variability in opioid prescribing in veterans affairs emergency departments and urgent cares

OBJECTIVE

The Veterans Health Administration (VHA) is the largest integrated health care system in the U.S., serving approximately 2.5 million Veterans in the Emergency Department/Urgent Care Centers (ED/UCC) each year. Variation in opioid prescribing by ED/UCC providers in the VHA is described.

METHODS

This is an observational study using administrative data from the VHA Pharmacy Benefits Management Services database to assess ED/UCC providers' opioid prescribing rates between October 1st, 2014 to June 30th, 2017 in 121 U.S. facilities. The opioid prescribing rate was defined as the number of opioid prescriptions written by the provider divided by the number of patients discharged from the ED/UCC by that provider, by quarter. A regression analysis was performed to estimate the association between time and prescribing rates by provider.

RESULTS

Overall, the national trend in median prescribing rates decreased by 25.5% (p value = 0.00) from 9.1% ([range 1.5%-25.6%] to 6.4% [range 0.8%-21.8%]). The greatest rates of decline occurred between January 1st, 2016 to June 30th, 2017. The rate of provider opioid prescribing demonstrated wide variability between facilities (range: 0.5% to 39.1%). The prescribing rate for ED/UCC providers ranged from 0.2% to 100%. Between June 2016 and May 2017, 24 VHA ED/UCC providers were the highest opioid prescribers nationally in at least two of the four quarters (22%-70%), with rates two- to three-fold higher than their peers.

CONCLUSION

ED/UCC providers in the VHA system nationally vary considerably in rates of opioid prescribing. A focused initiative tailored for ED/UCC providers is needed to decrease opioid prescribing variability.

Clinical Policy Recommendations from the VHA State-of-the-Art Conference on Non-Pharmacological Approaches to Chronic Musculoskeletal Pain

As a large national healthcare system, Veterans Health Administration (VHA) is ideally suited to build on its work to date and develop a safe, evidence-based, and comprehensive approach to the care of chronic musculoskeletal pain conditions that de-emphasizes opioid use and emphasizes non-pharmacological strategies. The VHA Office of Health Services Research and Development (HSR&D) held a state-of-the-art (SOTA) conference titled "Non-pharmacological Approaches to Chronic Musculoskeletal Pain Management" in November 2016. Goals of the conference were (1) to establish consensus on the current state of evidence regarding non-pharmacological approaches to chronic musculoskeletal pain to inform VHA policy in this area and (2) to begin to identify priorities for the future VHA research agenda. Workgroups were established and asked to reach consensus recommendations on clinical and research priorities for the following treatment strategies: psychological/behavioral therapies, exercise/movement therapies, manual therapies, and models for delivering multimodal pain care. Participants in the SOTA identified nine non-pharmacological therapies with sufficient evidence to be implemented across the VHA system as part of pain care. Participants further recommended that effective integration of these non-pharmacological approaches across the VHA and especially into VHA primary care, pain care, and mental health settings should be a priority, and that these treatments should be offered early in the course of pain treatment and delivered in a team-based, multimodal treatment setting concurrently with active self-care and self-management approaches. In addition, we recommend that VHA leadership and policy makers systematically address the barriers to implementation of these approaches by expanding opportunities for clinician and veteran education on the effectiveness of these strategies; supporting and funding further research to determine optimal dosage, duration, sequencing, combination, and frequency of treatment; emphasizing multimodal care with rigorous evaluation grounded in team-based approaches to test integrated models of delivery and stepped-care approaches; and working to address socioeconomic and cultural barriers to veterans' access to non-pharmacological approaches.

Perioperative pain management: an update for obstetrician-gynecologists

The opioid epidemic in the United States is unprecedented and continues to worsen. Many opioid abusers obtain their pills through legitimate prescriptions, directly or indirectly, from a medical provider. While practitioners have a responsibility to treat pain, it is now becoming clear that aggressive opioid prescription practices contribute to an epidemic of abuse. The medical community has to balance the unintended consequences of opioid misuse and abuse with the need to provide adequate pain control. Additionally, providers are being held accountable by the legal system and professional organizations for their prescribing practices. Responsible use of opioids is paramount and pain control does not supersede safety. Effective and safe pain management requires that providers perform risk assessments, understand medication risks, avoid excessive reliance on opioids, and adequately monitor and educate patients. Obstetricians and gynecologists are uniquely positioned to influence pain management practices as primary care providers and surgeons who regularly manage both acute and chronic pain conditions. Therefore, the objective of this publication was to familiarize obstetricians and gynecologists with contemporary concepts in pain management and summarize recent guidelines in a manner that is applicable to our specialty. We focus on perioperative pain management, which is the time period immediately before, during, and after surgery. Topics reviewed include proper risk assessment to evaluate a patient's potential for poor pain control or development of chronic pain or misuse of opioids; multimodal pain management with nonpharmacological, nonopioid alternatives, safe opioid-use strategies; education and documentation; and special considerations for women, veterans, and lactation concerns.

Risk Factors for Serious Prescription Opioid-Induced Respiratory Depression or Overdose: Comparison of Commercially Insured and Veterans Health Affairs Populations

Objective

To characterize the risk factors associated with overdose or serious opioid-induced respiratory depression (OIRD) among medical users of prescription opioids in a commercially insured population (CIP) and to compare risk factor profiles between the CIP and Veterans Health Administration (VHA) population.

Subjects and Methods

Analysis of data from 18,365,497 patients in the IMS PharMetrics Plus health plan claims database (CIP) who were dispensed a prescription opioid in 2009 to 2013. Baseline factors associated with an event of serious OIRD among 7,234 cases and 28,932 controls were identified using multivariable logistic regression. The CIP risk factor profile was compared with that from a corresponding logistic regression among 817 VHA cases and 8,170 controls in 2010 to 2012.

Results

The strongest associations with serious OIRD in CIP were diagnosed substance use disorder (odds ratio [OR] = 10.20, 95% confidence interval [CI] = 9.06-11.40) and depression (OR = 3.12, 95% CI = 2.84-3.42). Other strongly associated factors included other mental health disorders; impaired liver, renal, vascular, and pulmonary function; prescribed fentanyl, methadone, and morphine; higher daily opioid doses; and concurrent psychoactive medications. These risk factors, except depression, vascular disease, and specific opioids, largely aligned with VHA despite CIP being substantially younger, including more females and less chronic disease, and having greater prescribing prevalence of higher daily opioid doses, specific opioids, and most selected nonopioids.

Conclusions

Risk factor profiles for serious OIRD among US medical users of prescription opioids with private or public health insurance were largely concordant despite substantial differences between the populations in demographics, clinical conditions, health care delivery systems, and clinical practices.
