Opioid tapering after surgery and its association with patient-reported outcomes and behavioral changes: a mixed-methods analysis.
Opioid tapering after surgery is recommended among patients with chronic opioid use, but it is unclear how this process affects their quality of life. The objective of this study was to evaluate how opioid tapering following surgery was associated with patient-reported outcome measures related to pain control and behavioral changes that affect quality of life. ⋯ Partial and complete opioid tapering within 90 days after surgery among patients with chronic opioid use was associated with improved patient-reported measures of pain control as well as behaviors that impact a patient's quality of life.

ReviewMultiorganizational consensus to define guiding principles for perioperative pain management in patients with chronic pain, preoperative opioid tolerance, or substance use disorder.
Significant knowledge gaps exist in the perioperative pain management of patients with a history of chronic pain, substance use disorder, and/or opioid tolerance as highlighted in the US Health and Human Services Pain Management Best Practices Inter-Agency Task Force 2019 report. The report emphasized the challenges of caring for these populations and the need for multidisciplinary care and a comprehensive approach. ⋯ This process produced seven guiding principles for the perioperative care of patients with chronic pain, substance use disorder, and/or preoperative opioid tolerance. These principles provide a framework and direction for future improvement in the optimization and care of 'complex' patients as they undergo surgical procedures.

The sodium-activated potassium channel Slack (KNa1.1, Kcnt1) plays a critical role in tuning neuronal excitability. Previous studies have revealed that Slack is expressed in neurons of the superficial dorsal horn of the spinal cord. However, the precise role of Slack in spinal dorsal horn neurons is unclear. ⋯ Unexpectedly, Lbx1-Slack-/- mice demonstrated increased scratching after intradermal injection of chloroquine, LY344864, and histamine. Moreover, neuromedin B receptors are coexpressed with Slack in the dorsal horn, and scratching after intrathecal delivery of neuromedin B was increased in Lbx1-Slack-/- mice. Our study provides in vivo evidence that Slack expressed in spinal dorsal horn neurons inhibits nerve injury-induced allodynia and acute itch induced by various pruritogens.

The outcome domains pain intensity, pain-related interference, side effects, (treatment) information, participation and personal interaction have all been identified as relevant factors in the management of perioperative pain. However, it is not yet clear which of these are particularly significant for the subjectively perceived overall quality of postoperative pain management. ⋯ The study demonstrates that personal interaction and the reduction of pain intensity and interference are three key factors that are significant for patients' experience of postoperative pain management. However, the extent to which the harmonisation of these three factors with those given prominence by HCP would positively impact postoperative pain management remains unclear and should be investigated further.
