Chronic pain is a common and serious problem for many patients. Treatment often includes non-pharmacological approaches despite the mostly flimsy evidence to support them. The objective of this study was to measure the feasibility and efficacy of hypnosis (including self-hypnosis) in the management of chronic pain in older hospitalized patients.
A single center randomized controlled trial using a two arm parallel group design (hypnosis versus massage). Inclusion criteria were chronic pain for more than 3 months with impact on daily life activities, intensity of > 4; adapted analgesic treatment; no cognitive impairment. Fifty-three patients were included. Pain intensity decreased significantly in both groups after each session. Average pain measured by the brief pain index sustained a greater decrease in the hypnosis group compared to the massage group during the hospitalization. This was confirmed by the measure of intensity of the pain before each session that decreased only in the hypnosis group over time. Depression scores improved significantly over the time only in the hypnosis group. There was no effect in either group 3 months post hospitals discharge.
The authors concluded that hypnosis represents a safe and valuable tool in chronic pain management of hospitalized older patients. In hospital interventions did not provide long-term post discharge relief.
So, hypnotherapy is better than massage therapy when administered as an adjunct to conventional pain management. As it is difficult to control for placebo effects, which might be substantial in this case, we cannot be sure whether hypnotherapy per se was effective or not.
Who cares? The main thing is to make life easier for these poor patients!
There are situations where I tend to agree with this slightly unscientific but compassionate point of view. Yes, the evidence is flimsy, but we need to help these patients. Hypnotherapy has very few risks, is relatively inexpensive and might help badly suffering individuals. In this case, does it really matter whether the benefit was mediated by a specific or a non-specific mechanism?
