The treatment of chronic pain is costly and frustrating for the patient, health care provider, and health care system. This is due, in part, to the complexity of pain symptoms which are influenced by behavior patterns, socioeconomic factors, belief systems, and family dynamics as well as by physiological and mechanical components. Assessment of treatment outcomes is often limited to the patient's subjective, multidimensional, self-reports. ⋯ In this study, a 36% reduction in clinic visits in the first year postintervention was found among the 109 patients who participated in an outpatient behavioral medicine program. Decreased clinic use continued in the first 50 patients followed 2 years postintervention. Decreased use projected to an estimated net savings of $12,000 for the first year of the study posttreatment and $23,000 for the second year.

Clinical Trial Controlled Clinical Trial
Placebo-controlled trial of dexamethasone for chronic biliary pain after cholecystectomy.
Activation of the sympathetic nervous system appears to be relevant in some patients with unexplained pain after cholecystectomy, particularly those who show increases in plasma transaminase activity after challenge with morphine (morphine responders). In this study, the hypothesis that dexamethasone would improve chronic biliary pain, perhaps by suppressing activation of the sympathetic nervous system, was tested in a double-blind, placebo-controlled, cross-over trial in 20 patients, 10 morphine responders and 10 nonresponders. ⋯ During treatment with dexamethasone, 1 mg each night for 4 weeks, neither morphine responders nor nonresponders showed a significant improvement in pain or nausea or a significant reduction in sympathoadrenomedullary activity as assessed by urinary excretion of catecholamines. At the dose administered, dexamethasone was unhelpful for chronic pain after cholecystectomy and did not result in suppression of the sympathetic nervous system as assessed by urinary excretion of NE.

Individuals with chronic pain frequently experience a complex and convoluted journey through the health care system that is often unrewarding for all involved. Excessive pain behavior may lead to unnecessary diagnostic testing or invasive procedures and result in iatrogenic complications and prolonged disability. ⋯ Often there is no direct correlation between objective impairment and an individual's request for disability status. As job satisfaction and financial security diminish during our economic recession, the impact of the disability epidemic becomes more profound.

Comparative Study
A comparison of models describing reports of disability associated with chronic pain.
We examined pain-related disability from two perspectives. A disability model, suggesting that disability is a direct consequence of pain, is compared with a symptom perception model emphasizing individual differences in perception and report of physical symptoms. Disability estimates (reported activity interference and employment status) were obtained from a sample of 179 patients with chronic pain. ⋯ When we controlled for distress, the frequency of reporting physical symptoms made the largest contribution to prediction of this kind of disability (14%). Neither symptom report or pain intensity was useful in predicting the more objective disability criterion of employment status. Results were interpreted as probable evidence against a disability model of pain-related disability and suggest the relative importance of individual cognitive differences in symptom responsivity.
