Listed in Issue 229

Abstract

TEFIKOW and COLLEAGUES,  (1)Jena University Hospital, Friedrich Schiller University Jena, Institute of Psychosocial Medicine and Psychotherapy, Jena, Germany. susan.tefikow@med.uni-jena.de conducted a meta-analysis of published research to investigate the efficacy of hypnosis in adults undergoing surgical or medical procedures compared to standard care alone or an attention control.

Background

This meta-analysis investigates the efficacy of hypnosis in adults undergoing surgical or medical procedures compared to standard care alone or an attention control.

Methodology

Through a comprehensive literature search N=34 eligible randomized controlled trials (RCTs) were included, comprising a total of 2597 patients.

Results

Random effects meta-analyses revealed positive treatment effects on emotional distress (g=0.53, CI 95% [0.37; 0.69]), pain (g=0.44, CI 95% [0.26; 0.61]), medication consumption (g=0.38, CI 95% [0.20; 0.56]), physiological parameters (g=0.10, CI 95% [0.02; 0.18]), recovery (g=0.25, CI 95% [0.04; 0.46]), and surgical procedure time (g=0.25, CI 95% [0.12; 0.38]).

Conclusion

In conclusion, benefits of hypnosis on various surgically relevant outcomes were demonstrated. However, the internal validity of RCTs seems limited and further high methodological quality RCTs are needed to strengthen the promising evidence of hypnosis for adults undergoing surgery or medical procedures.
