Gabapentinoid (GABA) prescribing has substantially increased while opioid prescribing has decreased since the 2016 Centers for Disease Control and Prevention Guidelines restricted opioid prescribing for chronic pain. The shift to GABA assumes equal analgesic effectiveness to opioids, but no comparative analgesic effectiveness data exist to support this assumption. We compared GABA to opioids by assessing changes in pain interfering with activities (activity-limiting pain) over time in patients with chronic pain. ⋯ Gabapentinoid use had greater odds of less-than-daily pain post-prescription, in a dose-dependent manner. Thus, GABA use was associated with a larger reduction in chronic pain than opioids, with a larger effect at higher GABA dosage. Future research is needed on functional outcomes in patients with chronic pain prescribed GABA or opioids.

Comparative StudyComparison of the effects of OPRM1 A118G polymorphism using different opioids: A prospective study.
μ-opioid receptor gene (OPRM1) A118G polymorphism (rs1799971) causes loss of N-glycosylation sites at the extracellular domain of μ-opioid receptors. G-allele carriers show a limited response to morphine; however, studies investigating the impact of A118G polymorphism on the efficacy of opioids other than morphine are limited. ⋯ Tapentadol and methadone may be more suitable than hydromorphone, oxycodone, and fentanyl for G-allele carriers due to their dual mechanism of action and low susceptibility to OPRM1 A118G polymorphism.

Inequitable access to nonpharmacologic pain treatment providers among cancer-free U.S. adults.
Using evidence-based nonpharmacologic pain treatments may prevent opioid overuse and associated adverse outcomes. There is limited data on the impact of access-promoting social determinants of health (SDoH: education, income, transportation) on use of nonpharmacologic pain treatments. Our objective was to examine the relationship between SDoH and use of nonpharmacologic pain treatment providers. Our goal was to understand policy-actionable factors contributing to inequity in pain treatment. ⋯ These findings highlight the substantial influence access-promoting SDoH have on pain treatment utilization.

Outcome optimization after the placement of a spinal cord stimulator (SCS) is critical. The objective of this study was to determine if an association existed between pre-procedural opioid use (compared to patients who were opioid-naïve) and postoperative long-term outcomes following SCS placement. ⋯ Patients requiring preoperative opioids before SCS placements had increased odds of SCS explantation at 6 months and 12 months, as well as increased odds of reoperation at 6 months.
