Dialectical Pain Management: Feasibility of a Hybrid Third-Wave Cognitive Behavioral Therapy Approach for Adults Receiving Opioids for Chronic Pain.

OBJECTIVES: This study evaluated the feasibility, acceptability, and potential effectiveness of a hybrid skills-based group intervention, dialectical pain management (DPM), for adults with chronic pain who are receiving long-term opioid therapy. DPM adapts dialectical behavior therapy, a rigorous psychotherapeutic approach to emotion dysregulation, to treat disorders of physiological dysregulation. METHODS: Individuals with chronic pain (N = 17) participated in one of two 8-week DPM intervention cohorts. At pre-test and post-test, participants completed quantitative self-report assessments measuring pain intensity and interference, depressive symptoms, pain acceptance, beliefs about pain medications, and global rating of change. Within 2 weeks after the intervention, participants completed qualitative interviews to assess participant satisfaction and obtain feedback about specific intervention components. RESULTS: Of the 17 enrolled, 15 participants completed the group with 12 (70%) attending six or more sessions. Participants reported high satisfaction with the intervention. Preliminary findings suggested a significant increase in pain acceptance and a significant reduction in depressive symptoms. Participants also reported an improved relationship with their pain conditions and increased flexibility in responding to pain and applying coping skills. Several participants showed a reduction in opioid dosage over the course of the intervention. DISCUSSION: Findings support that DPM is a feasible and well-received intervention for individuals with chronic pain. Additional research with a control group is needed to further determine the intervention's efficacy and impact.

Understanding the relationship between features associated with pain-related disability in people with painful temporomandibular disorder: an exploratory structural equation modeling approach.

Pain-related disability is a multifaceted construct that refers to the impact of pain on an individual's capacity to fulfill their self-defined and social roles. This research examined the relationship between clinical, psychological, and pain sensitivity factors and pain-related disability among adults with chronic temporomandibular disorder (TMD). We analyzed data from a cross-sectional community-based sample of 1088 men and women with chronic TMD. We first constructed and tested a measure of pain-related disability (ie, pain impact), including a variable assessing presenteeism, created measurement models of jaw limitation, psychological unease (negative affect, somatic symptoms, and catastrophizing), and experimental pain sensitivity (eg, pressure pain threshold, thermal tolerance, and mechanical pressure pain threshold). Subsequently, latent variables were combined in a structural equation model. Participants (n = 1088) were 18 to 44 years old (mean 29.2, SD ± 7.8) whose chronic TMD had persisted, on average, for 6.9 years (SD ± 6.4). A model of pain-related disability, jaw limitation, and psychological unease was created and refined with exploratory model revisions to account for correlation among variables. Estimation of the final model indicated excellent fit with the data (root-mean-square error of approximation = 0.048, root-mean-square error of approximation 90% confidence interval [CI] 0.043-0.053, comparative fit index = 0.956, standardized root-mean-square residual = 0.040). Jaw functional limitation and psychological unease was strongly related to pain-related disability. Experimental pain sensitivity was removed from our model because of weak direct effect and the burden of performing experimental pain sensitivity testing in a clinical setting. The final model explained 78% of the variance in pain-related disability.

Characteristics Associated With High-Impact Pain in People With Temporomandibular Disorder: A Cross-Sectional Study.

High-impact (disabling) pain diminishes the quality of life and increases health care costs. The purpose of this study was to identify the variables that distinguish between high- and low-impact pain among individuals with painful temporomandibular disorder (TMD). Community-dwelling adults (N = 846) with chronic TMD completed standardized questionnaires that assessed the following: 1) sociodemographic characteristics, 2) psychological distress, 3) clinical pain, and 4) experimental pain. We used high-impact pain, classified using the Graded Chronic Pain Scale, as the dependent variable in logistic regression modeling to evaluate the contribution of variables from each domain. Cross-validated area under the receiver operating characteristic curve (AUC) quantified model discrimination. One-third of the participants had high-impact pain. Sociodemographic variables discriminated weakly between low- and high-impact pain (AUC = .61, 95% confidence interval [CI] = 0.57, 0.65), with the exception of race. An 18-variable model encompassing all 4 domains had good discrimination (AUC = 0.79, 95% CI = 0.75, 0.82), as did a simplified model (sociodemographic variables plus catastrophizing, jaw limitation, and number of painful body sites) (AUC = 0.79, 95% CI = 0.76, 0.82). Duration of pain, sex, and experimental pain testing results were not associated. The characteristics that discriminated most effectively between people with low- and high-impact TMD pain included clinical pain features and the ability to cope with pain. PERSPECTIVE: This article presents the results of a multivariable model designed to discriminate between people with high- and low-impact pain in a community-based sample of people with painful chronic TMD. The findings emphasize the importance of catastrophizing, jaw limitation, and painful body sites associated with pain-related impact.

Air-fluidized therapy in patients with suspected deep tissue injury: a case series.

PURPOSE: The evolution of suspected deep tissue injuries from an initial purple bruise to a significant stage III or IV pressure ulcer may be rapid, even with optimal treatment. This case series describes our experience with air-fluidized therapy (AFT) placed upon discovery of suspected deep tissue injury (sDTI) in an acute care setting. CASES: Five patients with 10 sDTIs were placed on AFT within 12 hours of sDTI diagnosis and evaluated for an average of 9 days. Patients were included in the series if they met the height and weight range of the bed and presented with, or developed an sDTI. Standard wound care included the use of an ointment containing trypsin, Balsam of Peru, and castor oil (Vasolex; Stratus Pharmaceuticals Inc, Miami, Florida) applied directly to both intact skin and open areas comprising the sDTI. Patients were repositioned per standard hospital care. Although we were unable to prevent skin breakdown in every case, findings suggest that interventions resulted in a reduction in the magnitude of tissue loss, including prevention of stage III to IV pressure ulceration in all 5 patients. The cost of a 9-day length of stay on the AFT bed is estimated at less than $700 per patient, which is far less than the reported cost to treat a stage III/IV wound ($10,845 US per patient in 2009 dollars). CONCLUSION: Our experience described in these cases suggests that the use of AFT may be clinical and cost-effective for prevention of progression of sDTI in critically ill patients. Additional research in this area should be encouraged.

Endovenous thermal ablation of superficial venous insufficiency of the lower extremity: single-center experience with 3000 limbs treated in a 7-year period.

PURPOSE: To demonstrate that endovenous thermal ablation is not only effective and safe but also a durable treatment in patients with symptomatic varicose veins. METHODS: From February 2002 to February 2009, 2354 patients (1836 women; mean age 53 years, range 15-95) with symptomatic varicose veins in 3000 limbs underwent endovenous laser ablation (EVLA) or radiofrequency ablation (RFA). The majority of treated vessels were the great saphenous veins (GSV; 2619, 87.3%); 269 (8.9%) small saphenous veins (SSV) and 112 (3.8%) accessory saphenous veins (ASV) were also treated, all in outpatient procedures under local intra-compartmental anesthesia. An ultrasound evaluation was performed within 2 weeks of the procedure to evaluate vein occlusion, vein wall thickness, and clot extension into the deep vein. In a long-term evaluation involving the first 165 patients treated from February 2002 to January of 2003, 105 (64%) patients [126 (67%) of the 188 eligible limbs] were followed annually with clinical evaluation, duplex ultrasound, and symptom/satisfaction assessment over a mean 6.7 years. RESULTS: Treatment of 3000 limbs involved the use of EVLA in 2841 (2460 GSVs, 269 SSVs, and 112 ASVs) and RFA in 159 GSVs. Post-procedure duplex ultrasound found 57 (2.0%) veins recanalized or incompletely occluded [51 (2%) treated with EVLA and 6 (3.7%) with RFA] in patients treated for GSV or ASV incompetence. In the 269 SSVs treated (all with EVLA), 18 (6.7%) limbs demonstrated incomplete occlusion. Overall, both EVLA and RFA procedures were well tolerated, with minimal complications. In the longitudinal assessment of the 105 patients (126 limbs) participating in annual follow-up for a mean 6.7 years, the overall rate of satisfaction, symptom relief, and absence of varicosities was 86%. CONCLUSION: Endovenous ablation of saphenous vein has proven to be an effective, safe, and very durable procedure.

Endovenous ablation of incompetent saphenous veins: a large single-center experience.

PURPOSE: To evaluate the effectiveness of endovenous treatment of symptomatic varicose veins using the endovenous laser (EVL) or radiofrequency (RF) energy over a >3-year follow-up. METHODS: From February 2002 to August 2005, 981 consecutive patients (770 women; mean age 51 years, range 15-90) with symptomatic varicose veins in 1250 lower limbs underwent endovenous ablation of 1149 great saphenous veins (GSV) and 101 small saphenous veins (SSV) under tumescent anesthesia without intravenous sedation or regional anesthesia. There were 990 GSV and 101 SSV procedures using EVL; 159 GSVs were treated with RF energy. An ultrasound evaluation was performed within 2 weeks of the procedure to evaluate occlusion of the vein, wall thickness, and clot extension into the deep venous system. Follow-up from the first 200 procedures in the series included clinical evaluation and duplex ultrasound scanning at 6 and 12 months and annually thereafter. RESULTS: Of the 1149 GSVs treated, 39 (3.4%) recanalizations were seen in 33 of the EVL and 6 of the RF procedures for inadequate treatment as judged by ultrasound. There were 9 (9.0%) failures among the 101 SSVs treated with EVL. Overall, both EVL and RF procedures were well tolerated, with only minor complications. One obese patient with ulcer developed pulmonary embolus on the fourth postoperative day. There were no differences between EVL and RF in efficacy or complications. Follow-up at a mean 3 years (range 30- 42 months) in 143 treated limbs showed no neovascularization in the groin. CONCLUSION: Outcomes with EVL and RF were good, with low complication rates that may be related to the use of local tumescent anesthesia without intravenous sedation.
