title: Should placebo be used routinely for chronic pain in older people?
abstract: As research expands our understanding of underlying placebo mechanisms, interest turns to the clinical application of placebos. Whether placebos are appropriate and effective in the management of chronic pain in older people deserves considerable attention. The evidence suggests that adults of any age are responsive to placebos, and that placebo treatments can be effective for many conditions prevalent in older people. Though placebos in general already seem to be used with some regularity in medical practice, the use of placebos alone for chronic pain is probably unjustified unless other treatments are inadvisable or have been exhausted. However maximising the mechanisms that underpin placebo analgesia such as expectancy or the psychosocial context should be encouraged and would be considered a feature of good clinical practice. It would also be anticipated that older people may see an additional benefit with placebo treatments when such treatments reduce existing or planned medication regimes, as older people typically experience more comorbidities, increased susceptibility to adverse drug reactions, and altered pharmacological responses to drugs. Further research is still needed in placebo-related treatment paradigms for the management of chronic pain in older people.
