To address the ongoing opioid epidemic, there has been an increased focus on the treatment and evaluation of opioid use disorder (OUD). OUD and chronic pain (CP) frequently co-occur; however, little is known about the additional comorbidities that present when they occur together as compared to when either condition presents alone. Using data from Fiscal Year 2012 Veteran's Health Administration, all veterans diagnosed with both OUD + CP were compared to those diagnosed with OUD or CP alone on socioenvironmental characteristics, medical and mental health diagnoses, and Veterans Affairs (VA) clinical service use. Veterans with OUD + CP ( = 33,166), compared to those with OUD only (n = 12,517), had higher numbers of medical conditions. Compared to those with CP only ( = 2,015,368), veterans with OUD + CP had higher rates of homelessness and substance use diagnoses. Most mental health diagnoses, numbers of psychotropic medication fills, opioid prescriptions, and use of all other services were higher in the OUD + CP group than in either single disorder group. Multinomial regression analysis revealed stronger effects for medical disorders and medical-surgical outpatient service use in the comparison of OUD + CP with OUD only and stronger effects for substance use and mental health disorders and use of prescription opiates in the comparison with CP only. These findings suggest that concurrent OUD + CP imposes exceptional disease and clinical service burdens that likely require the development of simultaneous, integrated approaches to treatment.

Learn More >To investigate the effects of a group-based cognitive behavioural intervention for patients with persistent low back pain (LBP) and psychological risk factors referred to secondary care.
Learn More >Chronic pain (CP) commonly presents alongside psychiatric conditions such as depression, PTSD, and generalized anxiety. The current study sought to better understand this complex relationship by determining whether anxiety and depression symptom severity mediated the relationship between DSM-5 PTSD symptom clusters and pain symptoms in a sample of 663 Canadian Armed Forces (CAF) personnel and veterans seeking treatment for mental health conditions.
Learn More >The evaluation and treatment of patients with epilepsy is not limited to the type of epilepsy, but it must incorporate the common comorbid neurologic, psychiatric, and medical disorders, as the latter can bare an impact on the course and response to treatment of the seizure disorder and vice versa. In this article we review the bidirectional relations among epilepsy and two of its most common comorbidities, mood disorders and migraine and examine the implications of these relations on the selection of therapies of these three disorders and their response to treatment. We also review the most salient common pathogenic mechanisms that may explain such relations.
Learn More >The goal of this study was to understand perspectives on whether a new diagnostic entity, distinct from Diagnostic and Statistical Manual – 5 (DSM-5) opioid use disorder (OUD), is needed for patients with chronic pain on long-term opioid therapy (LTOT) for whom the harms of continued opioid therapy outweigh the benefits. Data were collected as part of a larger Delphi study. We used rapid and thematic qualitative methods to analyze data from 51 panelists with expertise in internal medicine, psychiatry, psychology, and related fields. Three-quarters of panelists supported a new diagnostic entity; common themes included recognizing distinct experiences of patients prescribed LTOT, addressing problems with DSM-5 OUD criteria, facilitating research and improved treatment, and reducing stigma. Thirteen panelists opposed the creation of a new diagnostic entity; common themes included similarities in biological underpinnings of patients prescribed LTOT and diagnosed with OUD, belief that the continuum of OUD captured patients' experiences, finding better ways to address problems with DSM-5 OUD criteria, and concerns about stigma. While this expert panel disagreed about the need for a new diagnostic entity, there was an overall acknowledgement that the current implementation of DSM-5's OUD diagnosis is not meeting the needs of LTOT providers or patients. Perspective: The DSM-5's OUD diagnosis may not adequately meet the needs of patients on LTOT for whom the harms of continued opioid therapy outweigh the benefits. Experts do not agree on how to address this problem; more work is needed to determine if a new diagnostic entity would be beneficial.
Learn More >People with chronic pain engage in various strategies, such as pain catastrophizing and pain acceptance, to regulate the difficult emotional aspects of living with pain. Engagement in these strategies is known to influence pain severity and pain interference. However, less research has examined the extent to which general emotion regulation, the ability to identify emotions and engage in strategies to alter emotions, relates to pain-related outcomes. The current study, a large (N = 1453) online prospective study of adults with chronic pain, employed theory-driven assessment of emotion regulation to determine the extent to which general difficulties with emotion regulation at baseline relate to pain severity and pain interference at three-month follow-up, above and beyond pain catastrophizing and pain acceptance. We conducted a series of path models, controlling for demographic covariates and baseline pain severity and pain interference. Pain catastrophizing and pain acceptance at baseline significantly predicted pain interference at three-month follow-up. However, when indices of general emotion regulation were entered into the model, the associations between pain catastrophizing and pain interference (B = .009, p = .153) were no longer statistically significant. Alexithymia emerged as a significant predictor of pain severity (B = .012, p = .032) and pain interference (B = .026, p < .001). These findings highlight the value of considering the role of general emotion regulation (particularly identifying and describing emotions), in addition to pain-specific experiences, in understanding risk for poor pain-related outcomes. PERSPECTIVE: : In addition to pain catastrophizing and pain acceptance, difficulties regulating emotions in general (particularly elevated alexithymia) relates to pain outcomes three months later. These findings shed light on risk for poor pain outcomes and point to general emotion regulation as a potentially important target of chronic pain intervention.
Learn More >Studies have identified high rates of chronic postsurgical pain in adolescents. Characterizing patterns of pain in the transition from acute to chronic following major surgery may pinpoint critical periods of recovery. This observational study modelled pain trajectories over 1-year following surgery to attempt replication of prior work and evaluate baseline psychosocial factors and 12-month health outcomes. Adolescents 10-18 years completed electronic daily pain reporting for 7 days and self-reported health outcomes, at 5 assessment timepoints. Group-based trajectory modelling identified two trajectories with similar starting points in-hospital but distinct recovery courses at home. Pain declined steadily in one group across the study period ("Declining Pain"; estimated probability,18.9%), but pain increased after hospital discharge and remained high through 12-months in the other group ("High and Persistent Pain"; estimated probability,81.1%). Pre-surgery pain (aOR=1.86,p=0.001) and sleep quality (aOR=0.49,p=0.029) were associated with the High and Persistent pain trajectory in multivariate regressions. This trajectory was associated with lower total quality of life (B=-9.79,p=0.002), physical health (B=-15.93,p<0.001), psychosocial health (B=-6.73,p=0.06), and greater fatigue (B=-13.61,p=0.001). This study replicated prior findings identifying two post-surgical pain trajectories with diverging pain in the first two weeks. Clinical detection of those with increasing pain and early intervention may interrupt persistence of pain. PERSPECTIVE: . This article replicates a prior study identifying distinct post-surgical pain trajectories, Declining Pain and High and Persistent Pain. The High and Persistent pain trajectory is associated with pre-surgery pain, pre-surgery sleep quality, and lower quality of life (total, physical, and psychosocial health as well as fatigue) at 12-month follow-up.
Learn More >A remote (telephone and tool kit) chronic pain program was studied using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. This 6-week pilot took place in underserved communities in Cleveland, Ohio. We determined reach by the diversity of the population, nearly 50% Black and mostly low income. Effectiveness over 7 weeks was shown with validated instruments (depression, pain, sleep, quality of life, self-rated health, and self-efficacy). Changes in pain, depression, and self-efficacy were significant. ( < .01). Remote implementation was accomplished by sending participants a box of materials (book, exercise and relaxation CDs, a self-test, and tip sheets). Participants also participated in peer-facilitated weekly scripted telephone calls. Maintenance was demonstrated as the study site has offered nine additional programs with more plan. In addition, 60 additional organizations are now offering the program. This proof-of-concept study offers an alternate to in-person chronic pain self-management program delivery.
Learn More >Pain is known to be socioeconomically patterned and associated with disability. However, knowledge is scarce concerning life-course socioeconomic circumstances and pain among young adults. Our aim was to examine the associations of childhood and current socioeconomic circumstances with acute pain and chronic pain with low and high disability levels among young Finnish municipal employees.
Learn More >Patients rarely dispose of left-over opioids after surgery. Disposal serves as a primary prevention against misuse, overdose, and diversion. However, current interventions promoting disposal have mixed efficacy. Increasing disposal in rural communities could prevent or reduce the harms caused by prescription opioids.
