Other studies of opioid therapy have found that patients who developed problems with their medication all had a history of substance abuse [Portenoy and Foley buy super avana 160 mg with amex erectile dysfunction frustration, 1986; Taub buy discount super avana 160 mg on-line erectile dysfunction treatment by homeopathy, 1982]. However, inaccurate and underreporting of medication use by patients complicates assessment [Fishbain et al. Not infrequently, prior substance abuse history emerges only after current misuse has been identified, thus requiring physicians to be vigilant over the course of treatment. In patients with chronic pain who did develop new substance use disorders, the problem most commonly involved the medications prescribed by their physicians [Long et al. The causes and onset of substance use disorders have been difficult to characterize in relationship to chronic pain. During the first 5 years after the onset of chronic pain, patients are at increased risk for developing new substance use disorders and additional physical injuries [Brown et al. A cycle of pain followed by relief after taking medications is a classic example of operant reinforcement of future medication use that eventually becomes abuse [Fordyce et al. Drug-seeking behavior may be the result of a depressed patient trying to achieve or maintain a previous level of pain control. In this situation, the patient’s actions likely represent pseudoaddiction that results from therapeutic dependence and current or potential undertreatment but not addiction [Kirsh et al. Conclusion Chronic pain is exacerbated by comorbid depression, and depression is exacerbated by chronic pain. There is ample evidence that both conditions are underrecognized and undertreated. It is also clear that both problems pose significant public health problems and associated with enormous financial costs. There is accumulating evidence that the cost of treatment is trivial compared to the cost of ongoing disability and suffering. Specialty recognition of the inter- action between these two conditions and the development of comprehensive treatment plans involving multiple specialists are imperative. Unfortunately, in the climate of cost containment and fiscal responsibility over the short term, the long-term costs of these problems have accelerated with the closure of programs specifically designed to care for these patients. All physicians must advocate for better care of these patients but the provision of interdisciplinary specialty clinics that can formulate cases with the complexities described must be provided and funded. Perspectives on Pain and Depression 19 Each perspective of an interdisciplinary formulation has a unique logic that defines specific methods for designing treatment for the patient with depression and chronic pain. The patient does not have to fit into one theoreti- cal approach or model in order to receive and accept treatment. The patient’s treatment is based on the formulation, which becomes rational instead of pro- grammatic. The linkages and interactions of a patient’s diagnoses can then be investigated within a framework that includes the entire person and not just their biochemistry. If a patient’s suffering persists, other factors must be considered that may have been overlooked before the treatment plan is abandoned or modified. Usually these factors are within one of the perspectives initially thought to be less important. A new combination of approaches is then required to treat the patient successfully. The perspectives appreciate that the patient is strug- gling through important life events, but also that he is a person composed of vulnerabilities and strengths, having made many choices, and afflicted by diseases.
