Objectives To assess the efficacy of a self-management group intervention in improving physical functioning, mood, and pain among elderly persons with chronic pain, and to identify factors that may be associated with improvement. Materials and Methods Forty-five residents of three retirement communities (86% women; mean age, 82.0 years) were assigned randomly to a 7-week pain self-management group or an educational booklet control condition. Participants completed self-report measures of pain, functioning, depression, and pain-related beliefs at baseline, 9 weeks later (after treatment), and 3 months after the post-treatment assessment. Results The self-management group showed significantly greater pre- to post-treatment improvement in physical role function (P = 0.04) and characteristic pain intensity (P = 0.02). No significant differences were found between groups on measures of pain-related activity interference, depression, and pain-related beliefs. Improvement in characteristic pain and physical role function was not associated with baseline depression scores, pretreatment expectations, or changes in pain-related beliefs. Discussion This study provides preliminary support for the efficacy of a self-management group intervention for older adults with chronic pain and has implications for future studies of such approaches for this and similar populations.
Chronic pain in persons with spinal cord injury (SCI) is a difficult problem for which there is no simple method of treatment. Few randomized controlled trials of medications for pain in persons with SCI have been conducted. This study was designed to determine whether amitriptyline, a tricyclic antidepressant, is efficacious in relieving chronic pain and improving pain-related physical and psychosocial dysfunction in persons with SCI. Eighty-four participants with SCI and chronic pain were randomized to a 6-week trial of amitriptyline or an active placebo, benztropine mesylate. All pre- and post-treatment assessments were conducted by evaluators blind to the allocation. Regression analyses were conducted to examine whether there was a medication group effect on the primary (average pain intensity) and secondary outcome measures. No significant differences were found between the groups in pain intensity or pain-related disability post-treatment, in either intent-to-treat analyses or analyses of study completers. These findings do not support the use of amitriptyline in the treatment of chronic pain in this population, but we cannot rule out the possibility that certain subgroups may benefit.
A systematic literature synthesis was performed to analyze the long-term risks and benefits of spinal cord stimulation for patients with failed back surgery syndrome. Relevant articles were identified through a MEDLINE search (January 1966-June 1994), bibliography reviews, searches of personal files, and literature supplied by a stimulator manufacturer. Two investigators independently reviewed each article to determine whether it met the following study inclusion criteria: 1) original data on return to work, pain, medication use, reoperations, functional disability, or stimulator use after permanent implantation of spinal cord stimulators in patients with chronic low back or leg pain despite previous back surgery; and 2) follow-up > or = 30 days for all patients. Articles were excluded if data from patients with other diagnoses were mixed with (and could not be separated from) data from patients with chronic low back or leg pain, or if their data were redundant with those reported in an included article. Articles written in languages other than English or French were excluded. Thirty-nine studies, all case studies, were analyzed. At follow-up (mean, 16 mo; range, 1-45 mo), an average of 59% of patients had > or = 50% pain relief (range, 15-100% of patients). Complications occurred in 42% of patients but were generally minor. It seems that approximately 50 to 60% of patients with failed back surgery syndrome report > 50% pain relief with the use of spinal cord stimulation at follow-up; the lack of randomized trials precludes conclusions concerning the effectiveness of spinal cord stimulation relative to other treatments, placebo, or no treatment.
This study compared the abilities of the MMPI and Millon Clinical Multiaxial Inventory (MCMI), using discriminant analyses, to predict outcome after lumbar laminectomy for chronic back pain. Sixty-nine males and 60 females with lumbar discogenic disease completed MMPIs and MCMIs before surgery and were classified as either having good or fair/poor surgical outcomes based on self-reported pain relief, return to work, restriction of activities, and medication use. Results showed both the MMPI and MCMI to have moderate ability to predict surgery outcome. A slightly higher classification hit rate was obtained with both instruments when age, sex, employment status, and presence of compensation/litigation issues also were entered into the prediction equation. Results indicate the need for caution in using either instrument to make predictions of surgery outcome in individual cases.
Increases in prescriptions of opioid medications for chronic pain have been accompanied by increases in opioid overdoses, abuse, and other harms and uncertainty about long-term effectiveness.To evaluate evidence on the effectiveness and harms of long-term (>3 months) opioid therapy for chronic pain in adults.MEDLINE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, PsycINFO, and CINAHL (January 2008 through August 2014); relevant studies from a prior review; reference lists; and ClinicalTrials.gov.Randomized trials and observational studies that involved adults with chronic pain who were prescribed long-term opioid therapy and that evaluated opioid therapy versus placebo, no opioid, or nonopioid therapy; different opioid dosing strategies; or risk mitigation strategies.Dual extraction and quality assessment.No study of opioid therapy versus no opioid therapy evaluated long-term (>1 year) outcomes related to pain, function, quality of life, opioid abuse, or addiction. Good- and fair-quality observational studies suggest that opioid therapy for chronic pain is associated with increased risk for overdose, opioid abuse, fractures, myocardial infarction, and markers of sexual dysfunction, although there are few studies for each of these outcomes; for some harms, higher doses are associated with increased risk. Evidence on the effectiveness and harms of different opioid dosing and risk mitigation strategies is limited.Non-English-language articles were excluded, meta-analysis could not be done, and publication bias could not be assessed. No placebo-controlled trials met inclusion criteria, evidence was lacking for many comparisons and outcomes, and observational studies were limited in their ability to address potential confounding.Evidence is insufficient to determine the effectiveness of long-term opioid therapy for improving chronic pain and function. Evidence supports a dose-dependent risk for serious harms.Agency for Healthcare Research and Quality.
The relationship between patient expectations about a treatment and the treatment outcomes, particularly for Complementary and Alternative Medicine (CAM) therapies, is not well understood. Using qualitative data from a larger study to develop a valid expectancy questionnaire for use with participants starting new CAM therapies, we examined how participants' expectations of treatment changed over the course of a therapy. We conducted semi-structured qualitative interviews with 64 participants initiating one of four CAM therapies (yoga, chiropractic, acupuncture, massage) for chronic low back pain. Participants just starting treatment were interviewed up to three times over a period of 3 months. Interviews were transcribed verbatim and analyzed using a qualitative mixed methods approach incorporating immersion/crystallization and matrix analysis for a decontexualization and recontextualization approach to understand changes in thematic emphasis over time. Pre-treatment expectations consisted of conjecture about whether or not the CAM therapy could relieve pain and improve participation in meaningful activities. Expectations tended to shift over the course of treatment to be more inclusive of broader lifestyle factors, the need for long-term pain management strategies and attention to long-term quality of life and wellness. Although a shift toward greater acceptance of chronic pain and the need for strategies to keep pain from flaring was observed across participants regardless of therapy, participants varied in their assessments of whether increased awareness of the need for ongoing self-care and maintenance strategies was considered a "positive outcome". Regardless of how participants evaluated the outcome of treatment, participants from all four therapies reported increased awareness, acceptance of the chronic nature of pain, and attention to the need to take responsibility for their own health. The shift in treatment expectations to greater acceptance of pain and the need for continued self-care suggests that future research should explore how CAM practitioners can capitalize on these shifts to encourage feelings of empowerment rather than disappointment surrounding realizations of the need for continued engagement with self-care.
