Pain and withdrawal are common among patients receiving medications for opioid use disorder and associated with pain catastrophizing, negative affect, and poor sleep.

Abstract

Substantial percentages of persons receiving medications for opioid use disorder (MOUD) continue to experience clinically significant levels of pain and opioid withdrawal, which may pose barriers to reducing opioid use. Continued pain, in particular, may increase the risk for psychiatric problems and poorer treatment retention, especially with a lack of adequate care for pain. The goals of these analyses were to characterize the prevalence of, and patient-level variables associated with, pain and opioid withdrawal, as well as utilization of related coping strategies and treatments. Participants were 18 years of age or older and received methadone or buprenorphine for opioid use disorder (n = 179). Participants completed this survey in person, within their MOUD clinic. Participants completed patient-level and demographic questions as well as measures of pain, withdrawal, utilization of related coping strategies, and pain treatment. Numerous participants endorsed chronic pain (41.9%) or opioid withdrawal (89.4%) and indicated reliance upon over-the-counter medications and prayer for pain management. Multiple linear regression models showed greater pain catastrophizing and negative affect accounted for variability in pain severity and pain interference, as well as opioid withdrawal. Persons who slept less and endorsed chronic pain also reported greater pain severity and interference, and pain interference was higher with increased age. These and previous findings combine to further highlight the detrimental role that pain catastrophizing and negative affect can play in pain perception and withdrawal, but also represent promising treatment targets to facilitate pain and withdrawal management and improved quality of life.
