Chronic pain is a significant comorbid condition among individuals with opioid use disorder (OUD). However, due to conflicting perceptions of responsibility, structural barriers, and a lack of widely applied standards of care, it is unclear what the landscape of chronic pain management looks like in addiction medicine. Using a national opioid surveillance system, we analyzed survey data from new entrants (n = 14,449) to 225 OUD treatment centers from 2013 to 2018, as well as an online survey among a subset of respondents (n = 309). ⋯ In order to improve poor outcomes among OUD patients, interdisciplinary collaboration/care, along with evidence-based policies or processes for quality pain management in addiction care need to be prioritized. PERSPECTIVE: This article suggests chronic pain is commonly reported, yet not managed by many OUD treatment programs, increasing the likelihood of opioid relapse. In order to improve low retention and success rates among OUD patients, interdisciplinary collaboration, evidence-based policies or processes (eg, referral) for quality pain management in addiction care need to be prioritized.

Adequate analgesia can be challenging, as pharmacological options are not necessarily effective for all types of pain and are associated with adverse effects. Methadone is increasingly being considered in the management of both cancer-related and noncancer-related pain. The purpose of this article is to provide a narrative review of all available randomized controlled trials (RCTs) investigating the effectiveness of methadone in the management of pain, in relation to a comparison drug. ⋯ Future research should also aim to standardize reported outcomes for measuring analgesic effectiveness to permit for pooled analysis across studies. PERSPECTIVE: This article presents a systematic review, which includes a summary of published RCTs investigating the effectiveness of methadone in the management of pain. This is important for determining its analgesic utility and for identifying gaps in existing knowledge.

Randomized Controlled Trial
Transcranial direct current stimulation accelerates the onset of exercise-induced hypoalgesia: a randomised controlled study.
Exercise-induced hypoalgesia (EIH) describes acute reductions in pain that occur following exercise. Current evidence suggests that the magnitude of EIH is small-to-moderate at best, warranting exploration of novel avenues to bolster these effects. Transcranial direct current stimulation (tDCS) has been shown to relieve pain and represents a promising intervention that may enhance EIH. ⋯ PERSPECTIVE: These findings suggest that active tDCS accelerates the onset of EIH in healthy individuals experiencing experimentally-induced pain. This may represent a promising means of enhancing adherence to exercise protocols. However, larger randomised controlled trials in persistent pain populations are required to confirm the clinical impact of these findings.

Review
CHRONIC OPIOID THERAPY: A SCOPING LITERATURE REVIEW ON EVOLVING CLINICAL AND SCIENTIFIC DEFINITIONS.
The management of chronic noncancer pain (CNCP) with chronic opioid therapy (COT) is controversial. There is a lack of consensus on how COT is defined resulting in unclear clinical guidance. This scoping review identifies and evaluates evolving COT definitions throughout the published clinical and scientific literature. ⋯ An increasing proportion of studies define COT as ">90 days' supply." The most recent literature trends toward shorter duration criteria, suggesting that contemporary COT definitions are increasingly conservative. PERSPECTIVE: This study summarized the most common, current definition criteria for chronic opioid therapy (COT) and recommends adoption of consistent definition criteria to be utilized in practice and research. The most recent literature trends toward shorter duration criteria overall, suggesting that COT definition criteria are increasingly stringent.

Randomized Controlled Trial
A cost-effectiveness analysis of an internet-delivered pain management program delivered with different levels of clinician support: Results from a randomised controlled trial.
There is growing interest in the potential of internet-delivered pain management programs (PMPs) to increase access to care for people with chronic pain. However, very few economic evaluations of these interventions have been reported. Using existing data, the current study examined the cost-effectiveness of an internet-delivered PMP for a mixed group chronic pain patients (n = 490) provided with different levels of clinician support. ⋯ These findings suggest that carefully developed and administered internet-delivered PMPs, provided with different levels of clinician support, can be highly cost effective for patients with a broad range of pain conditions. PERSPECTIVE: This study examines the cost-effectiveness of an internet-delivered PMP provided to adults with a broad range of chronic pain conditions. Evidence of cost-effectiveness was found across a broad range of clinical outcomes and with different levels of clinician support.
