The indications for initiating long-term opioid treatment (L-TOT) for chronic non-cancer pain (CNCP) are often unclear and associated with problematic use. This study aimed at evaluating the efficacy of stabilizing opioid therapy followed by a sequential opioid tapering off program in CNCP patients. ⋯ This trial showed that sequential tapering off L-TOT in CNCP patients may be an unfeasible approach. However, improvements after opioid treatment stabilization were achieved and stable pain intensity in those tapered off may encourage the development of more refined programs.

The evidence for Internet-delivered pain management programs for chronic pain is growing, but there is little empirical understanding of how they effect change. Understanding mechanisms of clinical response to these programs could inform their effective development and delivery. ⋯ This study employed robust statistical techniques to assess the psychological mechanisms of an established internet-delivered pain management program. While clinical improvements (e.g. depression, anxiety, pain) were closely associated with improvements in psychological variables (e.g. pain self-efficacy and pain acceptance), these variables do not appear to be treatment mechanisms.

Incidence and risk factors for chronic pain after elective caesarean delivery under spinal anaesthesia in a Chinese cohort: a prospective study.
China has one of the highest rates of caesarean delivery in the world. The aim of this study was to investigate the incidence and risk factors for chronic pain after caesarean delivery in a Chinese cohort. ⋯ Chronic pain after elective caesarean delivery under spinal anaesthesia occurs infrequently, especially in the long-term, in a Chinese population. Patients with a previous caesarean delivery and higher analgesic use were at increased risk.

ReviewPredicting Severity of Acute Pain After Cesarean Delivery: A Narrative Review.
Cesarean delivery is one of the most common surgical procedures in the United States, with over 1.3 million performed annually. One-fifth of women who undergo cesarean delivery will experience severe pain in the acute postoperative period, increasing their risk of developing chronic pain and postpartum depression, and negatively impacting breastfeeding and newborn care. A growing body of research has investigated tools to predict which patients will experience more severe pain and have increased analgesic consumption after cesarean delivery. ⋯ Thirteen articles were included in the final review: 5 utilizing quantitative sensory testing, including patient responses to pressure, electrical, and thermal stimuli; 1 utilizing hyperalgesia testing; 1 using response to local anesthetic wound infiltration; 4 utilizing preoperative psychometric evaluations including the State-Trait Anxiety Inventory, the Pain Catastrophizing Scale, the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, and simple questionnaires; and 2 utilizing a combination of quantitative sensory tests and psychometric evaluations. A number of modalities demonstrated statistically significant correlations with pain outcomes after cesarean delivery, but most correlations were weak to modest, and many modalities might not be clinically feasible. Response to local anesthetic infiltration and a tool using 3 simple questions enquiring about anxiety and anticipated pain and analgesic needs show potential for clinical use, but further studies are needed to evaluate the utility of these predictive tests in clinical practice.
