The current study tested whether a therapeutic assessment improved pain and well-being in couples facing chronic pain. Couples (N = 47) in which 1 spouse had chronic pain completed surveys about pain, mood, marital satisfaction, and empathy, followed by an interview and an assessment session to which they were randomly assigned: a tailored assessment of their marriage and pain coping that incorporated motivational interviewing strategies, or a control condition that included education about the gate control theory of pain. Multilevel modeling revealed that couples in the motivational assessment group experienced significant decreases in pain severity and negative mood, and increases in marital satisfaction and positive mood from baseline to postassessment, relative to the education control group. All participants experienced increases in empathy toward their partner except for spouses in the control group, who experienced declines in spousal empathy. The motivational assessment and control groups did not experience differential change in any of the variables at 1-month follow-up. Moderators of improvement were also explored, including age, race, gender, education, pain duration, spouse pain status, and marriage duration. The results provide preliminary evidence for the short-term benefits of a brief motivational assessment to improve psychosocial functioning in both patients and spouses. ⋯ This article presents preliminary evidence in support of a brief therapeutic psychosocial assessment for couples with chronic pain. Assessments such as this may potentially help patients and their spouses feel more optimistic about pain treatment and increase the likelihood of entering treatment.

Contemporary medical education is inadequate to prepare medical students to competently assess and design care plans for patients with acute and chronic pain. The time devoted to pain education in most medical school curricula is brief and not integrated into case-based clinical experiences, and it is frequently nonexistent during clinical clerkships. Medical student pain curricula have been proposed for over 30 years and are commonly agreed upon, though rarely implemented. As a consequence of poor undergraduate pain education, postgraduate trainees and practicing physicians struggle with both competency and practice satisfaction; their patients are similarly dissatisfied. At the University of Washington School of Medicine, a committee of multidisciplinary pain experts has, between 2009 and 2011, successfully introduced a 4-year integrated pain curriculum that increases required pain education teaching time from 6 to 25 hours, and clinical elective pain courses from 177 to 318 hours. It is expected that increased didactic and case-based multidisciplinary clinical training will increase knowledge and competency in biopsychosocial measurement-based pain narrative and risk assessment, improve understanding of persistent pain as a chronic complex condition, and expand the role of patient-centered interprofessional treatment for medical students, residents, and fellows, leading to better prepared practicing physicians. ⋯ Strategies for improving multidisciplinary pain education at the University of Washington School of Medicine are described and the preliminary results demonstrated.

Randomized Controlled Trial
Focal modulation of the primary motor cortex in fibromyalgia using 4×1-ring high-definition transcranial direct current stimulation (HD-tDCS): immediate and delayed analgesic effects of cathodal and anodal stimulation.
Fibromyalgia is a prevalent chronic pain syndrome characterized by altered pain and sensory processing in the central nervous system, which is often refractory to multiple therapeutic approaches. Given previous evidence supporting analgesic properties of noninvasive brain stimulation techniques in this condition, this study examined the effects of a novel, more focal method of transcranial direct current stimulation (tDCS), using the 4×1-ring configuration of high-definition (HD)-tDCS, on overall perceived pain in fibromyalgia patients. In this patient- and assessor-blind, sham-controlled, crossover trial, 18 patients were randomized to undergo single 20-minute sessions of anodal, cathodal, and sham HD-tDCS at 2.0 mA in a counterbalanced fashion. The center electrode was positioned over the left primary motor cortex. Pain scales and sensory testing were assessed before and after each intervention. A finite element method brain model was generated to predict electric field distribution. We found that both active stimulation conditions led to significant reduction in overall perceived pain as compared to sham. This effect occurred immediately after cathodal HD-tDCS and was evident for both anodal and cathodal HD-tDCS 30 minutes after stimulation. Furthermore, active anodal stimulation induced a significant bilateral increase in mechanical detection thresholds. These interventions proved well tolerated in our patient population. ⋯ 4×1-ring HD-tDCS, a novel noninvasive brain stimulation technique capable of more focal and targeted stimulation, provides significant reduction in overall perceived pain in fibromyalgia patients as compared to sham stimulation, irrespective of current polarity. This technique may have other applications in research and clinical settings, which should be further explored.

Opiate use for chronic pain is becoming increasingly controversial. There has been a shift away from supporting the use of opiates for treatment of chronic pain. In addition to lack of effectiveness, concerns for adverse clinical outcomes, addiction, and death have provided the impetus for this change. The purpose of this study was to investigate the percent of trauma patients still using opiates, their pain levels, and psychological outcomes 4 months posttrauma. This was a study to evaluate chronic pain at 4 months posttrauma in 101 participants from a single level 1 trauma center. Eighty of the 101 participants developed chronic pain 4 months after their initial traumatic injury (79%). Of those who developed chronic pain, 27 (26%) were still using opiates. Those using narcotics at 4 months posttrauma had significantly more pain, life interference, depression, and anxiety. Posttraumatic stress disorder (PTSD) was not significantly influenced by narcotic use in this analysis. However, the mean associated with those using narcotics was higher and diagnostic for PTSD. Those taking opiates did not have significantly better relief from their pain using treatments or medications than those not using opiates (F = 8, P = .08). These findings bring into question the appropriate use of opiates for chronic pain and the possible exacerbating effects on pain and psychopathology in traumatically injured patients. ⋯ This article identifies data that provide evidence that narcotic pain medication needs to be used carefully in traumatically injured patients with chronic pain, especially in those individuals with comorbid psychological pathology.
