To the Editor: Jon Streltzer, M.D. and Luther Johansen, M.D. presented a case of an unfortunate woman, a chronic pain patient, who developed an addiction to multiple drugs, including opioids, and finally overdosed. They use this case to develop a position against chronic opioid analgesic therapy, which they describe as a “medical subculture (1, p. 506).”
On behalf of Pain Medicine, we would like to take issue with some of the statements in this article that we consider inaccurate, as they are not adequately referenced.
Multidisciplinary pain centers did not develop to treat chronic pain patients with pain out of proportion to objective findings but to treat intractable chronic pain patients who had multiple comorbidities (2).
Treatment usually included detoxification because opioids were thought (with little evidence) to invariably cause addiction and decrease function (2).
Additional evidence (3) now supports the concept of “pseudoaddiction,” originally based on one case report.
Contrary to their assertion of little evidence for chronic opioid analgesic therapy effectiveness, there is significant evidence for the efficacy, safety, and improvement in function with chronic opioid analgesic therapy. Two meta-analyses (4, 5) of more than 40 placebo-controlled chronic opioid analgesic therapy pain studies both showed opioids as more effective than placebo, and one (5) demonstrated improved functional outcomes. A structured evidence-based review (6) of 11 studies (2,877 patients) concluded that long-term chronic opioid analgesic therapy can lead to significant functional improvement. Other evidence suggests that chronic opioid analgesic therapy may be associated with low risk of abuse/addiction (2).
Many of the over 50 million American chronic pain patients benefit from management that includes opioids. Addiction disorders occur in 10%–15% of these patients and in the general population without pain. We must train physicians to treat pain effectively and safely based on evidence, including managing risks such as addiction.
