Longitudinal treatment outcomes for geriatric patients with chronic non-cancer pain at an interdisciplinary pain rehabilitation program.

OBJECTIVE: This study examined depression, pain catastrophizing, psychosocial functioning, and physical and emotional health attributes for geriatric patients admitted to an interdisciplinary pain rehabilitation center compared with middle and younger age groups. DESIGN: Quasi-experimental time series. SETTING: Interdisciplinary pain rehabilitation center at a tertiary referral medical center. PATIENTS: In total, 411 patients with chronic non-cancer pain completed the pain rehabilitation program from October 2004 to April 2006. Patients were divided into three groups based on age: older (ages 60+; n = 78); middle-age (ages 40-59; n = 230) and younger (ages 18-39; n = 141). INTERVENTION: A 3-week outpatient interdisciplinary pain rehabilitation program based on a cognitive-behavioral model that incorporates opioid withdrawal. OUTCOME MEASURES: The Multidimensional Pain Inventory (MPI), Short Form-36 Health Status Questionnaire (SF-36), Pain Catastrophizing Scale (PCS), and Center for Epidemiological Studies-Depression Scale (CES-D) were administered at admission, discharge, and 6 months following treatment. The frequency of patients using opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), and benzodiazepines at each assessment point were compared. RESULTS: Older patients reported reduced depression, catastrophizing, pain severity, and pain interference (P < 0.001) at discharge and 6 months follow-up. Older patients also reported increased perceived control, and physical and social functioning at discharge and follow-up (P < 0.001). Improvement in older patients was comparable in magnitude to that of middle-age patients on all variables, whereas younger patients exhibited greater improvement on four variables. Significant reductions in analgesic use were observed in all groups. CONCLUSION: Interdisciplinary pain rehabilitation incorporating opioid withdrawal can improve long-term psychological, social and physical functioning for geriatric chronic pain patients.

Reduction in medication costs for patients with chronic nonmalignant pain completing a pain rehabilitation program: a prospective analysis of admission, discharge, and 6-month follow-up medication costs.

OBJECTIVE: Chronic nonmalignant pain (CNMP) is both a prevalent and a costly health problem in our society. Pain rehabilitation programs have been shown to provide cost-effective treatment. A treatment goal for some rehabilitation programs is reduction in the use of pain-related medication. Medication costs savings from pain rehabilitation programs have not been analyzed in previous studies. DESIGN: This prospective cohort study of 186 patients with CNMP addresses the costs of medications at admission to a 3-week outpatient pain rehabilitation program, at discharge, and at 6-month follow-up. Medication use was determined through a detailed pharmacist interview with patients at admission and discharge. Patients were sent questionnaires 6 months after program completion, which obtained current medication information. RESULTS: Statistically significant medication cost savings were seen for program completers at discharge and at 6-month follow-up (P < 0.05). The mean (standard deviation) daily prescription medication cost reduction from admission to discharge was $9.31 ($12.70) using the average wholesale price of medications. From the original study cohort, 121 patients completed the 6-month follow-up survey. The mean daily prescription medication cost savings from admission to 6-month follow-up was $6.68 ($14.40). CONCLUSION: Patients benefited from significant medication cost savings at the completion of the 3-week outpatient pain rehabilitation program and maintained significant savings after 6 months. This study adds to the current literature on the economic value of comprehensive pain rehabilitation programs.

Chronic pain rehabilitation in chronic headache disorders.

This article reviews the treatment goals and efficacy of comprehensive pain rehabilitation programs for the treatment of chronic headache. Substantial data demonstrate improved outcomes from rehabilitative treatment for chronic noncancer pain. We present a discussion of the most relevant recent publications on pain rehabilitation in chronic headache disorders. This article describes pain rehabilitation, reviews outcome data for chronic pain patients treated in this setting, and describes the unique applicability of this treatment approach for patients with chronic headache. Particular attention is directed to the rationale for and the results of the withdrawal, in a pain rehabilitation setting, of opioids and simple analgesics, ergots, and triptans that contribute to medication overuse headaches. Additionally, a case example is reviewed that illustrates the structure and function of a pain rehabilitation program in the treatment of a patient with intractable headache.

A longitudinal study of the efficacy of a comprehensive pain rehabilitation program with opioid withdrawal: comparison of treatment outcomes based on opioid use status at admission.

UNLABELLED: Use of opioids for chronic non-cancer pain is controversial and the efficacy of comprehensive pain rehabilitation programs (CPRPs) that incorporate opioid withdrawal requires further investigation. We test the hypothesis that patients with chronic pain and longstanding opioid use who undergo opioid withdrawal in the course of rehabilitative treatment will experience significant and sustained improvement in pain and functioning similar to patients who were not taking opioids. A longitudinal design study compared 373 consecutive patients admitted to the Mayo Clinic Pain Rehabilitation Center at admission, discharge and six-month posttreatment by opioid status at admission. Measures of pain severity, depression, psychosocial functioning, health status, and pain catastrophizing were used to assess between- and within-group differences. Treatment involved a 3-week interdisciplinary pain rehabilitation program focused on functional restoration. Over one-half of patients (57.1%) were taking opioids daily at admission. The majority of patients (91%) completed rehabilitation and 70% of patients who completed the program returned questionnaires six months posttreatment. On admission, patients taking low- and high-dose opioids reported significantly greater pain severity (P=.001) and depression (P=.001) than the non-opioid group. Significant improvement was found on all outcome variables following treatment (P<.001) and six-month posttreatment (P<.001) regardless of opioid status at admission. There were no differences between the opioid and non-opioid groups upon discharge from the program or at six months following treatment. CONCLUSION: Patients with longstanding CPRP on chronic opioid therapy, who choose to participate in interdisciplinary rehabilitation that incorporates opioid withdrawal, can experience significant and sustained improvement in pain severity and functioning.

Treatment outcomes after multidisciplinary pain rehabilitation with analgesic medication withdrawal for patients with fibromyalgia.

OBJECTIVE: This study of patients with a diagnosis of fibromyalgia (FM) was conducted to test the hypothesis that immediate posttreatment measures of psychosocial functioning, health attributes, negative pain-related emotions, and depressive symptoms improve significantly during multidisciplinary pain rehabilitation while concurrently withdrawing analgesic medications. DESIGN: Prospective case series. SETTING: Multidisciplinary pain rehabilitation center at a tertiary referral medical center. PATIENTS: In total, 159 consecutive patients with a diagnosis of FM admitted to the pain rehabilitation program from January 2002 to December 2003. INTERVENTIONS: A 3-week outpatient multidisciplinary pain rehabilitation program based on a cognitive-behavioral model that incorporates analgesic medication withdrawal. OUTCOME MEASURES: Multidimensional Pain Inventory (MPI), Short Form-36 Health Status Questionnaire (SF-36), Coping Strategies Questionnaire-Catastrophizing subscale (CSQ-C), and the Center for Epidemiologic Studies-Depression scale (CES-D) were administered at admission and dismissal and the mean differences in scores were compared using paired t-tests. The number of patients using opioid analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), benzodiazepines, and muscle relaxants at admission and dismissal were compared using chi-squared analyses. RESULTS: The difference in admission and dismissal scores from the MPI, SF-36, CSQ-C, and CES-D demonstrated a favorable response to treatment (P < 0.001). Compared with admission, the number of patients using opioids (P < 0.001), NSAIDs (P < 0.001), benzodiazepines (P < 0.001), and muscle relaxants (P < 0.01) at program dismissal was significantly reduced. CONCLUSION: The results of this study support the hypothesis that immediate posttreatment measures of physical and emotional functioning are favorable for patients with FM following multidisciplinary pain rehabilitation that incorporates withdrawal of analgesic medications.

The role of mental health professionals in multidisciplinary pain rehabilitation programs.

The traditional roles of psychologists and mental health therapists are challenged by the comprehensive treatment necessary for patients being treated in multidisciplinary pain rehabilitation programs (MPRPs). Mental health professionals within MPRPs provide direct clinical care but also guide the biopsychosocial model of pain management and cognitive-behavioral interventions for multiple disciplines. Illustrated by a case example of a patient who has complex chronic pain, this article discusses the biopsychosocial approach to pain treatment, structure of multidisciplinary care, major roles of mental health professionals in MPRPs, complexities of treating patients who have pain, and challenges in collaborating with multiple disciplines.

Slow-frequency rTMS reduces fibromyalgia pain.

OBJECTIVE: Evidence suggests that fibromyalgia (FM) is a centrally mediated pain disorder. Antidepressants, including electroconvulsive therapy, provide some symptomatic relief in FM and other pain disorders. Repetitive transcranial magnetic stimulation (rTMS) is a new antidepressant treatment, which may also be useful in treating chronic pain. DESIGN: As part of a larger study, four women with depression, FM, and borderline personality disorder received 1-Hz rTMS applied to the right dorsolateral prefrontal cortex. Subjects rated pain using an 11-point Likert scale. RESULTS: Pretreatment pain averaged 8.2 (7-9.5) and reduced to 1.5 (0-3.5) after treatment (P < 0.009). All had improvement in pain, and two had complete resolution of pain. Only one of the four subjects had an antidepressant response. CONCLUSIONS: These preliminary findings suggest a possible role for rTMS in treating FM.

Congenital idiopathic inability to perceive pain: a new syndrome of insensitivity to pain and itch with preserved small fibers.

Individuals vary widely in their sensitivity to painful stimuli. Some exhibit heightened reactions to pain (hyperpathia), while others show relative indifference. Although multiple factors may be responsible for these differences, varying sensitivities to pain also can be due to underlying differences in nociceptive neurophysiology. We present here the case of an individual with an apparent congenital inability to perceive pain. This patient appears to be different from other reported cases of insensitivity to pain described in the medical literature. He exhibited no evidence of an abnormality of the peripheral or autonomic nervous system and no apparent abnormality of the central nervous system other than isolated deficits in pain and temperature perception. Since pain is a subjective phenomenon, there is no definitive way to assess this patient's reported inability to perceive painful somatic stimulation, but available evidence suggests he has a defect in the supraspinal processing of nociceptive stimuli which renders him insensitive to pain. This raises the possibility of either deficient central nociceptive functioning or aberrant endogenous anti-nociceptive functioning.

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.

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.
