Interventions for the reduction of prescribed opioid use in chronic non-cancer pain.
CONCLUSIONS: There is no evidence for the efficacy or safety of methods for reducing prescribed opioid use in chronic pain. There is a small number of randomised controlled trials investigating opioid reduction, which means our conclusions are limited regarding the benefit of psychological, pharmacological, or other types of interventions for people with chronic pain trying to reduce their opioid consumption. The findings to date are mixed: there were reductions in opioid consumption after intervention, and often in control groups too. PMID: 29130474 [PubMed - as supplied by publisher]
