In-Person or Virtual Educational Preferences in Patients With Fibromyalgia: A Cross-Sectional Survey Study at an Academic Medical Center.

PURPOSE: Patient education is a core component of treating fibromyalgia and central sensitization disorders. We sought to evaluate whether patients with fibromyalgia prefer virtual or in-person educational classes as part of their treatment program, identify underlying factors with their educational modality choice, and highlight benefits or barriers associated with in-person or online educational sessions. DESIGN: A cross-sectional survey with a qualitative feedback component was utilized. METHODS: A voluntary, anonymous survey was distributed to all participants (in-person and virtual) of the fibromyalgia and chronic fatigue clinic treatment program from October 2021 through March 2022. RESULTS: In total 90 participants completed the survey. Nearly all (94%) agreed that the pathophysiologic education was relevant and valuable and (98%) agreed to feeling confident with implementing management strategies. Perceived connection between the participants varied between groups (85% of in-person vs 48% of online; p < .001), as did perceived engagement (100% of in-person vs 71% of online; p = .001). CONCLUSIONS: Patients value education and find it useful in treating fibromyalgia, regardless of the educational modality. The online group reported more limitations including less engagement, class participation, and connection with peers. CLINICAL IMPLICATIONS: As virtual education platforms become more widely available and may be easier to access than in-person options, it is important to understand patient preferences, benefits, and disadvantages of educational modalities to ensure education and patient outcomes remain equitable.

Young Adult Pain Rehabilitation: Interdisciplinary Development and Preliminary Outcomes of a Novel Treatment Program.

BACKGROUND: Young adults with chronic pain and symptoms experience disruptions to their social, emotional, physical, and vocational functioning. Interdisciplinary pain rehabilitation programs for pediatric and adult populations are not designed specifically to address the developmental needs of young adults. METHODS: This article describes the development of a novel intensive interdisciplinary outpatient rehabilitation program tailored to the unique needs of young adults with chronic pain and symptoms. Tailored content included vocational assessment and consultation, financial literacy education, and sexual health education. RESULTS: Outcome data demonstrate treatment gains, with reductions in pain interference, pain severity, pain catastrophizing, and depressive symptoms, as well as improvements in mental and physical quality of life, perceived performance, perceived satisfaction with performance, and objective measures of physical functioning. CONCLUSIONS: The article concludes with clinical recommendations for the management of chronic pain and symptoms in young adults, applicable across multiple treatment settings.

Fibromyalgia Pain and Fatigue Symptoms in Spanish and U.S. Men.

BACKGROUND AND AIMS: Fibromyalgia Syndrome (FMS) is a chronic centralized pain disorder characterized by widespread pain and fatigue. Of those affected by FMS, the majority are women, and minimal research exists involving men. The purpose of this paper is to describe the pain and fatigue experiences of men with FMS from two Western countries, Spain and the United States, in order to support more accurate and earlier recognition and diagnosis in men. DESIGN AND METHODS: We used individual and focus group interviews with qualitative and quantitative assessments. SETTINGS AND PARTICIPANTS/SUBJECTS: Ten men in Spain and seven men in the United States provided information about their symptoms, psychosocial and health-seeking behaviors, and gender experiences with FMS. RESULTS: Men articulated types, trends, and triggers of pain and fatigue that enrich an understanding of their symptoms. For example, men report more localized pain than generalized pain. Employment status and activities, among other contextual factors, impacted men's pain and fatigue experiences. CONCLUSIONS: Men experience distinct facets of pain and fatigue compared with women, with notable similarities and differences across the Spanish and U.S. SAMPLES: Cross-cultural comparisons highlight contextual factors that may inspire future inquiries about determinants of men's experiences with FMS. CLINICAL IMPLICATIONS: The present study could be useful for anyone treating men suffering from FMS, especially care providers in nursing, medical, and psychology fields. These initial findings may prompt a closer examination of recommendations for assessment and diagnostic criteria used internationally for patients with FMS with better recognition of men's experience.

The Perception of Female Smokers with Fibromyalgia on the Effects of Smoking on Fibromyalgia Symptoms.

OBJECTIVE: Smokers with fibromyalgia have greater pain intensity and function impairment compared to nonsmokers. Patients' perceptions of interactions between smoking and fibromyalgia symptoms have not been described. The primary aim of this study was to report the perceptions of female smokers with fibromyalgia on how smoking affects symptoms. METHODS: Forty-eight daily smokers with fibromyalgia enrolled in the Mayo Clinic Fibromyalgia Treatment Center completed the Fibromyalgia Impact Questionnaire, Fagerstrom Test for Nicotine Dependence, Patient Health Questionnaire-9, General Anxiety Disorder-7 and a Fibromyalgia Symptoms and Smoking Survey which queried how smoking directly affected fibromyalgia symptoms (eg, pain, tiredness/fatigue, stiffness, nervousness/anxiety, depression/blueness, irritability, concentration, and overall) or indirectly as a coping mechanism. RESULTS: The majority of subjects reported smoking had no direct effect on fibromyalgia physical symptoms (pain [60% reported no effect], fatigue [56%], stiffness [81%]) but direct improvement of emotional symptoms (anxiety [62% reported improvement], irritability [64%]). The majority of subjects used smoking to cope with pain (69%) via distraction (83%) and relaxation (77%), lessening emotional distress by reducing a sense of frustration (83%) or sadness (54%) because of pain, and as a justification for resting vis-à-vis "smoke breaks" (69%). Thirty-one smokers were mildly and 17 moderately/severely dependent on tobacco, and no difference in fibromyalgia impact score (P = 0.70), pain (P = 0.39), depression (P = 0.20), and anxiety (P = 0.64) scores were detected, but more moderately/severely dependent subjects reported smoking improved pain (50% vs. 17%, P = 0.04). DISCUSSION: Smokers with fibromyalgia reported smoking helped to cope with fibromyalgia pain but generally did not directly ameliorate fibromyalgia physical symptoms.

Association of abuse history with symptom severity and quality of life in patients with fibromyalgia.

A high prevalence of abuse has been reported in patients with fibromyalgia. We aimed to examine the association between self-reported abuse history and symptom severity and quality of life (QOL) in 962 patients with fibromyalgia. All patients completed the Fibromyalgia Impact Questionnaire (FIQ) and the Short Form 36 health survey (SF-36). Multivariate regression analyses were performed. In total, 289 patients (30%) reported a history of abuse. Of those who specified abuse types, 161 patients (59%) reported more than 1 type of abuse (36% emotional, 32% physical, 25% sexual, and 7% verbal). Patients in the abuse group were younger and more likely to be female, unemployed, unmarried, and current smokers compared with patients who reported no abuse. After adjusting for these differences, abuse history was associated with worse symptoms, as indicated by a higher FIQ total score (P < .001) and higher FIQ subscale scores in physical function (P = .001), work missed (P < .001), job ability (P < .001), pain (P = .02), depression (P < .001), and anxiety (P < .001). Similarly, abuse history was associated with worse QOL, with lower SF-36 scores in all domains except the physical component summary. In conclusion, abuse history in patients with fibromyalgia was associated with worse symptoms and QOL compared with those patients without abuse history. Future studies are needed to assess whether additional tailored interventions as part of fibromyalgia treatment are helpful for patients with a history of abuse.

Feasibility of interactive technology for symptom monitoring in patients with fibromyalgia.

Use of health information technology (IT) integrated with clinical services has the potential to empower self-management and decrease health care utilization for chronic disorders such as fibromyalgia (FM). However, the appropriate methodology that systematically facilitates the integration of health IT with clinical services between patients and nurses partnering to manage FM is unclear. The purpose of this study was to determine the feasibility of technology-enhanced monitoring that engages FM patients using a mobile device. A quantitative and qualitative descriptive design was used in a convenience sample of 20 FM patients. Patients used a mobile monitoring device for one week; nurses responded to patient e-mailed symptom reports on a daily basis. Analysis was primarily descriptive-percent, frequencies, and means for individual questionnaire items and subscales were calculated. For qualitative data, a 1 hour focus group was audio-recorded, transcribed verbatim, and then analyzed using content analysis. All participants used a mobile phone in their daily lives; half used a smart phone. Participants were interested in using a smart phone to monitor their health and to communicate with health care providers. Participants used the study mobile device an average of 5.2 days out of the 7 day study period. Most participants (80%) reported that monitoring symptoms using the device was easy to do. Sixty-five percent felt that using the device helped them to promptly address their symptoms. Results from this study indicated that health IT integrated with clinical services is feasible to monitor FM symptoms and to communicate with the care team.

Emotional experiences and gender roles of men with fibromyalgia syndrome: a cross-cultural qualitative study.

Introduction: Gender roles may impact men with fibromyalgia, causing a high number of negative emotional states and affective disorders. There are few studies that detect men's high emotional suffering. This study examined the emotional experience of men with fibromyalgia. Methods: A qualitative cross-cultural study utilized inductive thematic analysis was performed at the Fibromyalgia and Chronic Fatigue Unit Santa Maria University Hospital in Spain, the Fibromyalgia and Chronic Fatigue Clinic at Mayo Clinic in the US, and volunteers from the Winneshiek County in the US A total of 17 participants, 10 men from Spain and 7 men from the US were included. Results: Three themes related to feelings/emotions emerged: (1) psychological level; (2) social level; and (3) physical level. Men with fibromyalgia from Spain and the US experienced many negative emotions. Men often experience negative emotions that are worsened by common misunderstandings and social biases/stigma about their condition. Conclusion/implications: A proper assessment of emotions when evaluating the global health of men with fibromyalgia as well as the provision of emotional support would improve their mental health and therefore their overall physical health. Emotional management should be incorporated into all treatment protocols for fibromyalgia, especially for men given the gender stigma. Health policies designed by legislators, policymakers, and support agencies must be accompanied by education in gender role concepts to improve the emotions of men with FMS. The mass media will be essential for the disclosure of the emotional suffering of male patients so that society might better understand them.

Early experience with a brief, multimodal, multidisciplinary treatment program for fibromyalgia.

Fibromyalgia is a complex heterogeneous disorder for which a multidisciplinary individualized approach is currently advocated. We executed a 1-week multidisciplinary fibromyalgia clinical program with seven patients, based on our experience with our existing 1.5-day multidisciplinary fibromyalgia program that has demonstrated both short- and long-term benefits. The current expanded program was not designed as a clinical study, but rather as a clinical feasibility assessment, and it was multidisciplinary in nature, with cognitive behavioral therapy, activity pacing, and graded exercise therapy as major components. We assessed changes in individual patients at 1 week and 3 months after the program with the use of validated self-report measures of pain, fatigue, and self-efficacy. All patients indicated at least small improvements in pain and physical symptoms at both 1 week and 3 months, and all but one patient showed improvement in self-efficacy at 1 week and 3 months. Similar trends were observed for fatigue. Based on our early clinical experience, we conclude that the 1-week multidisciplinary fibromyalgia program is logistically feasible and has potential for clinical efficacy. Further research is needed and is planned to test the clinical efficacy of this program and compare it with other interventions.

Central sensitization, chronic pain, and other symptoms: Better understanding, better management.

Central sensitization, a pathophysiologic process in which the central nervous system undergoes changes that alter its processing of pain and other sensory stimuli, may be the mechanism underlying various conditions in which patients have unexplained pain and fatigue. Patients frequently misunderstand the cause of their symptoms and pursue unnecessary evaluations and treatments. Clinicians have a pivotal role in decreasing this misunderstanding by providing patient education, which can affect perception, management, functional status, and quality of life.

Physical Activity and Exercise Experience in Spanish and US Men with Fibromyalgia: A Qualitative Cross-Cultural Study.

Physical exercise is an indispensable element in the multidisciplinary treatment of fibromyalgia syndrome (FMS). The present study examined if men diagnosed with FMS engaged in any type of physical activity or exercise, the perceived effects from exercise, and who specifically recommended exercise. A qualitative cross-cultural study was performed in fibromyalgia clinical units in Spain and the United States. A total of 17 participants, 10 men from Spain and 7 men from the US, were included. In Spain, a focus group was completed in two parts, one month apart in 2018. In the US, five individual interviews and one joint interview with two men were completed in 2018. Three central themes appeared in the qualitative data: (1) Understanding what constitutes physical activity or exercise, (2) Facilitating or discouraging the performance of physical exercise, and (3) Effects of physical activity or exercise on psychological and social symptoms. The actual practice of exercise by patients with FMS is often perceived as leading to pain and fatigue, rather than a treatment facilitator. Physical activity and exercise can provide benefits, including relaxation, socialization, and increased muscle tone. However, minor opioids limit physical activity as they cause addiction, drowsiness, and decrease physical activity in Spanish men. Recommendations in a clinical setting should incorporate exercise as well as physical activity via daily life activities.

Creation of a Multispecialty Clinic for Patients with Central Sensitization-Based Chronic Pain Conditions.

OBJECTIVE: To design and evaluate, through a human-centered design approach, a multispeciality clinic for patients with central sensitization syndromes that combined virtual previsit consultations, traditional face-to-face appointments, and technology-enabled educational programming. PATIENTS AND METHODS: Patients with suspected fibromyalgia and chronic abdominal pain were seen in a multispecialty practice, and the performance of the clinic was evaluated against a contemporary cohort. Quantitative and qualitative evaluation measures included team estimates of time spent on care-related tasks, physician rank of alignment of patient need with clinic design, major appointment changes, and nonvisit care tasks. Members of the care team also evaluated strengths, weaknesses, opportunities, and threats to the success of the clinic. RESULTS: The pilot clinic was operated from April 1, 2020, to April 30, 2021, and included 34 patients with suspected fibromyalgia/chronic abdominal pain. During the pilot period, physicians ranked the value of the virtual previsit consultations in providing care as 7.5 on a scale of 0 to 10 and reported an average of 50 minutes in preparation for the appointment, execution of the appointment, and postvisit documentation. We did not observe substantial differences in the number of added appointments or messages received within the patient portal when compared with a comparison cohort. Patients who participated in the combination nurse educator-led and digital education program provided positive feedback about their experience. CONCLUSION: Our clinic model provides a framework for the treatment of patients with debilitating centrally sensitized conditions and future expansion of virtual care delivery models to better meet patient care and educational needs.

Dietary soy supplement on fibromyalgia symptoms: a randomized, double-blind, placebo-controlled, early phase trial.

Most patients with fibromyalgia use complementary and alternative medicine (CAM). Properly designed controlled trials are necessary to assess the effectiveness of these practices. This study was a randomized, double-blind, placebo-controlled, early phase trial. Fifty patients seen at a fibromyalgia outpatient treatment program were randomly assigned to a daily soy or placebo (casein) shake. Outcome measures were scores of the Fibromyalgia Impact Questionnaire (FIQ) and the Center for Epidemiologic Studies Depression Scale (CES-D) at baseline and after 6 weeks of intervention. Analysis was with standard statistics based on the null hypothesis, and separation test for early phase CAM comparative trials. Twenty-eight patients completed the study. Use of standard statistics with intent-to-treat analysis showed that total FIQ scores decreased by 14% in the soy group (P = .02) and by 18% in the placebo group (P < .001). The difference in change in scores between the groups was not significant (P = .16). With the same analysis, CES-D scores decreased in the soy group by 16% (P = .004) and in the placebo group by 15% (P = .05). The change in scores was similar in the groups (P = .83). Results of statistical analysis using the separation test and intent-to-treat analysis revealed no benefit of soy compared with placebo. Shakes that contain soy and shakes that contain casein, when combined with a multidisciplinary fibromyalgia treatment program, provide a decrease in fibromyalgia symptoms. Separation between the effects of soy and casein (control) shakes did not favor the intervention. Therefore, large-sample studies using soy for patients with fibromyalgia are probably not indicated.

Pain catastrophizing as a treatment process variable in cognitive behavioural therapy for adults with chronic pain.

BACKGROUND: Interdisciplinary cognitive behavioural therapy (CBT) for chronic pain is effective at improving function, mood and pain interference among individuals with disabling chronic pain. Traditionally, CBT assumes that cognitive change is an active therapeutic ingredient in the determination of treatment outcome. Pain catastrophizing, a cognitive response style that views the experience of pain as uncontrollable, permanent and destructive, has been identified as an important maladaptive cognition which contributes to difficulties with the management of chronic pain. Consequently, pain catastrophizing is commonly targeted in CBT for chronic pain. OBJECTIVES: To examine change trajectories in pain catastrophizing during treatment and assess the relevance of these trajectories to outcomes at posttreatment. METHODS: Participants included individuals with chronic pain (N = 463) who completed a 3-week program of interdisciplinary CBT. Pain catastrophizing was assessed weekly over the 3 weeks of treatment and latent growth curve modelling was used to identify trajectories of change. RESULTS: Findings indicated the presence of two classes of linear change, one with a significant negative slope in pain catastrophizing (i.e. improved class) and the other with a non-significant slope (i.e. unchanged class). Next, latent growth mixture modelling examined treatment outcome in relation to class membership. These results indicated that individuals in the 'improved' PCS class had significantly greater improvement in pain interference and mood, as well as physical and mental quality of life compared to the 'unchanged' class. CONCLUSIONS: Implications for our findings, in relation to the CBT model, are discussed.

Improving Distress and Behaviors for Parents of Adolescents With Chronic Pain Enrolled in an Intensive Interdisciplinary Pain Program.

OBJECTIVES: Intensive interdisciplinary treatment is emerging as an effective treatment of chronic pain in youth. These programs often include a parental component with the belief that targeting parental distress and responses to a child's pain will improve outcomes. However, few studies have evaluated the impact of a parental intervention in the interdisciplinary treatment of pediatric chronic pain. The present study consists of a nonrandomized pre-post design to evaluate change in psychological and behavioral functioning of parents who participated in intensive parent programming that utilized cognitive-behavioral therapy and acceptance and commitment therapy, delivered within the context of an interdisciplinary intensive 3-week pain treatment program for youth with chronic pain. MATERIALS AND METHODS: Two hundred twelve parents and their children participated in the study, with 116 participants completing 3-month follow-up measures. Parents completed measures of depressive symptoms, pain catastrophizing, protective responses, and psychological flexibility at admission, discharge, and 3 months after the program. Child functional disability was assessed at the same time points. We examined change in parent factors over time, while controlling for change in child distress. RESULTS: Parents reported significant improvements in all areas of functioning from admission to discharge and improvements were maintained at 3-month follow-up. DISCUSSION: This study provides evidence suggesting parent interventions can be effective in reducing parent distress and behaviors known to be associated with child outcomes.

Longitudinal Treatment Outcomes for an Interdisciplinary Pain Rehabilitation Program: Comparisons of Subjective and Objective Outcomes on the Basis of Opioid Use Status.

Chronic pain is a major public health concern, and widespread use of prescription opioids for chronic pain has contributed to the escalating problem of opioid use disorder. Interdisciplinary pain rehabilitation programs (IPRPs) can be highly effective in discontinuing opioids in patients with chronic pain while also improving functional status. This study sought to examine self-report and performance-based functional outcomes of 2 cohorts of patients enrolled in a 3-week IPRP: patients engaged in interdisciplinary pain treatment and physician-supervised opioid taper versus nonopioid users engaged in interdisciplinary treatment. Immediate and long-term treatment outcomes were assessed using a series of 2 (group: opioid use, no opioid use) × 2 (period: pretreatment, post-treatment) and 2 (group: opioid use, no opioid use) × 2 (period: pretreatment, 6 months post-treatment) mixed model analyses of variance. Group × Period interactions were nonsignificant whereas period effects were significant for all outcomes in directions indicating improvement (Ps < .001) at discharge from the program and at 6 months, irrespective of opioid use status. Results support the assertion that IPRPs lead to significant improvements in subjective as well as objective indices of function, irrespective of opioid use status. Implications for our findings are discussed. PERSPECTIVE: This article provides support for the effectiveness of interdisciplinary, rehabilitative models of care in improving physical and emotional functioning of patients with chronic pain while simultaneously discontinuing opioid use. The reach of this work is substantial, because opioid dependency and chronic pain are public health problems in the United States.

Getting Back to Living: Further Evidence for the Efficacy of an Interdisciplinary Pediatric Pain Treatment Program.

OBJECTIVE: This study examined key functional outcomes following a 3-week interdisciplinary pediatric pain rehabilitation program for adolescents with chronic pain. Maintenance of gains was evaluated at 3-month follow-up. METHODS: Participants included 171 adolescents (12 to 18 y of age) with chronic pain who completed a hospital-based outpatient pediatric pain rehabilitation program. Participants completed measures of functional disability, depressive symptoms, pain catastrophizing, opioid use, school attendance, and pain severity at admission, discharge, and at 3-month follow-up. RESULTS: Similar to other interdisciplinary pediatric pain rehabilitation program outcome studies, significant improvements were observed at the end of the program. These improvements appeared to be maintained or further improved at 3-month follow-up. Nearly 14% of the patients were taking daily opioid medication at admission to the program. All adolescents were completely tapered off of these medications at the end of the 3-week program and remained abstinent at 3-month follow-up. DISCUSSION: This study adds to the available data supporting interdisciplinary pediatric pain rehabilitation as effective in improving functioning and psychological distress even when discontinuing opioids. Implications for future research and limitations of the study are discussed.

Improvement in Functioning and Psychological Distress in Adolescents With Postural Orthostatic Tachycardia Syndrome Following Interdisciplinary Treatment.

Significant functional impairment and psychological distress have been observed in adolescent patients with postural orthostatic tachycardia syndrome (POTS). Interdisciplinary rehabilitation programs have been shown to be beneficial in the treatment of chronic pain in adults and adolescents. Only preliminary data have examined interdisciplinary rehabilitation efforts in patients with POTS. This study evaluated the impact of an interdisciplinary rehabilitation program on the functional impairment and psychological distress in 33 adolescents diagnosed with POTS. Patients included in the study were adolescents ages 11 to 18 diagnosed with POTS. Measures completed at admission and discharge from the program included the Functional Disability Index, Center for Epidemiological Studies-Depression-Child scale, and the Pain Catastrophizing Scale for Children. After participation in the 3-week program, adolescents with POTS demonstrated a significant increase in overall functional ability and significant reductions in depression and catastrophizing.

Physical and emotional functioning of adult patients with chronic abdominal pain: comparison with patients with chronic back pain.

UNLABELLED: Adults with chronic abdominal pain remain a poorly defined population, despite the debilitation and depression associated with this therapeutically challenging condition. This study compared patients with chronic abdominal pain with an empirically well-known group of patients with chronic pain (back pain) to investigate similarities and differences in their physical and mental functioning. This retrospective, cross-sectional study included 136 patients with abdominal pain and 364 patients with back pain seen in a comprehensive pain rehabilitation center. Patients' functioning was assessed with the Short Form-36 Health Survey, Multidimensional Pain Inventory, Center for Epidemiological Studies-Depression scale, and Coping Strategies Questionnaire-Catastrophizing subscale. Both the abdominal and back pain patients reported long-standing and severe pain, numerous surgery procedures, poor functioning, and high prevalence of depression. When age, education, and marital status were controlled for, analyses showed that although patients with abdominal pain reported significantly better physical functioning than patients with back pain (P < .001), their overall health perception was significantly poorer (P < .001). Although less prevalent, it is clear that patients with chronic abdominal pain exhibit poor functioning and prevalence of depression that are comparable to patients with chronic back pain. This study also suggests distinct characteristics that are vital to consider for effective treatment of this chronic pain population. PERSPECTIVE: As a result of being an overlooked and poorly defined population, adults with chronic abdominal pain might not receive adequate pain management treatment. Learning more about the physical and emotional functioning of patients with long-standing abdominal pain can increase recognition of the needs of and improve treatment for this population.

Physical Trauma and Infection as Precipitating Factors in Patients with Fibromyalgia.

OBJECTIVE: The objective of this study was to evaluate both precipitating factors in patients with fibromyalgia and any differences in clinical presentation, symptom severity, and quality-of-life between those with and without precipitating physical trauma or infection. DESIGN: In a retrospective cross-sectional study, the authors compared patient characteristics and fibromyalgia symptom severity and quality-of-life with the Fibromyalgia Impact Questionnaire and the Short Form-36 Health Survey in patients seen in a fibromyalgia treatment program. RESULTS: Of 939 patients, 27% reported precipitating factors (trauma, n = 203; infection, n = 53), with the rest having idiopathic fibromyalgia (n = 683). Patients with precipitating trauma were more likely to have worse Fibromyalgia Impact Questionnaire physical function than patients with idiopathic onset (P = 0.03). Compared with patients with idiopathic onset and precipitating trauma, patients with precipitating infection were more likely to have worse Short Form-36 Health Survey physical component summary (P = 0.01 and P = 0.003) but better role emotional (P = 0.04 and P = 0.005), mental health index (P = 0.02 and P = 0.007), and mental component summary (P = 0.03 and P = 0.004), respectively. CONCLUSIONS: One-fourth of this study's patients with fibromyalgia had precipitating physical trauma or infection. Patients with precipitating infection had different sociodemographic characteristics, clinical presentation, and quality-of-life from the idiopathic and trauma groups. Further studies are needed to look into the relationships between precipitating events and fibromyalgia.

Chronic noncancer pain rehabilitation with opioid withdrawal: comparison of treatment outcomes based on opioid use status at admission.

OBJECTIVE: To study differences in treatment outcomes between patients with chronic noncancer pain taking vs those not taking maintenance opioids at admission to a pain rehabilitation program. PATIENTS AND METHODS: A nonrandomized 2-group prepost design was used to compare 356 patients admitted to the Mayo Comprehensive Pain Rehabilitation Center from January 2002 to December 2002 at admission and discharge by opioid status at admission. Measures of pain severity, interference due to pain, perceived life control, affective distress, activity level, depression, and catastrophizing (an exaggerated negative mental set associated with actual or anticipated pain experiences) were used to compare opioid and nonopioid groups. The patients entered a 3-week intensive outpatient multidisciplinary pain rehabilitation program designed to improve adaptation to chronic noncancer pain. The program uses a cognitive-behavioral model and incorporates opioid withdrawal. RESULTS: More than one third of patients (135/356) were taking opioids daily at admission. At completion of the program, all but 3 of the 135 patients had successfully discontinued opioid treatment. No significant pretreatment differences were found between the opioid and nonopioid group regarding demographics, pain duration, treatment completion, or all outcome variables, including pain severity. Significant improvement was noted at discharge for all outcome variables assessed regardless of opioid status at admission. CONCLUSION: Patients with symptomatically severe and disabling pain while taking maintenance opioid therapy can experience significant improvement in physical and emotional functioning while participating in a pain rehabilitation program that incorporates opioid withdrawal.
