The Debate Over Placebos in Pain Management

Should placebo be used routinely for chronic pain in older people?

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.

Placebo use in clinical practice by nurses in an Iranian teaching hospital

The present study was carried out to explore Iranian nurses' use of placebos in clinical practice and their knowledge and attitude towards its use. A cross-sectional, descriptive study was conducted using self-report questionnaires. All nurses working in a university hospital in Arak (n=342) were invited to participate in the study. Among 295 respondents, 221 (75%) reported that they had used at least one placebo within the past year and 179 (81%) told patients they were receiving actual medication. The most common reason and symptom for placebo use were after unjustified demand for medication and pain, respectively. Only 60 (20.33%) of the nurses believed that placebos should never be used. Results showed that most nurses in our study had used placebos and probably will continue to use them. Placebo use is viewed as ethically permissible among nurses. Some patients benefit from the placebos, but their use raises ethical questions. The role of placebo treatment, its mechanisms, and its ethics issues should be taught to nurses.

The right to pain treatment: a reminder for nurses

Critical care units are frequently the setting for the delivery of end-of-life care. A case study describing pain management for a terminally ill woman in an intensive care unit is used to illustrate conflicts that may be experienced by critical care nurses. The application of standards of professional organizations and regulatory bodies is described, as well as the ethical principles of autonomy, veracity, beneficence, nonmalfeasance, and double effect. Important legal and sociocultural considerations are included.
