Pain 2021 May 10. Epub 2021 May 10.

Pain Management Research Institute, Faculty of Medicine and Health, The University of Sydney, Sydney, Australia. School of Medicine and Public Health, University of Newcastle, NSW, Australia.

Abstract: Tapering opioids for chronic pain can be challenging for both patients and prescribers, both of whom may be unsure of what to expect in terms of pain, distress, activity interference, and withdrawal symptoms over the first few weeks and months of the taper. In order to better prepare clinicians to provide patient-centred tapering support, the current research used prospective longitudinal qualitative methods to capture individual-level variation in patients' experience over the first few months of a voluntary physician-guided taper. The research aimed to identify patterns in individuals' experience of tapering, and explore whether patient characteristics, readiness to taper, opioid-tapering self-efficacy, or psychosocial context were related to tapering trajectory.
