Background: Opioids are commonly used for postoperative pain management in spine surgery. However, few guidelines exist for appropriate prescribing in the acute postoperative phase of care. We identify risk factors for inpatient (IP) opioid use and examine relationships between IP requirements and discharge (DC) opioid prescriptions.
Methods: Retrospective review of elective spine surgeries between January 2014 and May 2018 identified cases of lumbar decompression (LD), LD with fusion (LDF), and cervical decompression with fusion (CDF) at our high-volume spine center. Multiple regression examining potential risk factors for opioid use was performed. Opioid use was normalized into daily morphine milligram equivalents (MME).
Results: A total of 2281 patients who underwent 1251 LD, 384 LDF, and 648 CDF procedures were identified (54.1% male, mean age = 57.9 years, mean body mass index = 30.3 kg/m, median American Society of Anesthesiologists [ASA] score = 2). Mean IP opioid use was 44.4 MME/day and average DC prescriptions totaled 496.5 MME. Multiple regression models identified younger age and increased ASA score as predictive of increased daily IP opioid consumption (β = -0.36, < .001, β = 10.1, < .001; = 0.308) and increased DC opioid amounts (β = -4.62, < .001, β = 72.1, < .001; = 0.097). Highest IP and DC opioid use was observed among LDF followed by CDF and LD patients. Significant positive correlations were found between IP opioid usage and DC opioid prescriptions by IP opioid quartiles ( = 0.99 LD, 0.98 LDF, 0.96 CDF).
Conclusions: Younger patients and higher ASA scores correlated with increased IP opioid use and DC opioid prescriptions. DC prescriptions appropriately reflect IP use.
Level Of Evidence: 3.
Clinical Relevance: Adequate pain management is an integral component to successful outcomes in spine surgery. Awareness of candidates likely to require higher levels of opioid analgesia will be beneficial in guiding surgeon prescribing practices.

Pain is a dynamic and nonlinear experience shaped by injury and contextual factors, including expectations of future pain or relief . While µ opioid receptors are central to the analgesic effects of opioid drugs, the endogenous opioid neurocircuitry underlying pain and placebo analgesia remains poorly understood. The ventrolateral column of the posterior periaqueductal gray is a critical hub for nociception and endogenous analgesia mediated by opioid signaling .

Clinical research on the long-term consequences of gestational opioid exposure reports increased rates of social, conduct, and emotional disorders in these children. Here, we investigate the impact of perinatal opioid exposure (POE) on behaviors associated with anhedonia and stress in male and female Sprague Dawley rats.

Severe SUD is characterized by drug-cue reactivity that predicts treatment-failure. We leveraged this pathophysiological feature to personalize deep brain stimulation (DBS) of the nucleus accumbens region (NAc) in an SUD patient.

Background: While Indigenous people are overrepresented in Canada's prisons and in the toxic drug supply crisis, we lack data on the harms related to opioids for Indigenous people with experiences of incarceration. We aimed to examine opioid toxicity deaths in Indigenous peoples who experienced incarceration and to compare opioid toxicity mortality rates with rates for people with no incarceration.
Methods: This retrospective cohort study linked correctional data for all people who were incarcerated in provincial correctional facilities and coronial data for all people who died from opioid toxicity in Ontario, Canada between 2015 and 2020.
Analysis of Analgesics and Adjuvant Medications on Psychiatric Comorbidities in Patients With Complex Regional Pain Syndrome 1.

Complex regional pain syndrome (CRPS) is a chronic pain disorder characterized by severe, disproportionate pain relative to an inciting event. The disorder's pathophysiology is complex, involving both central and peripheral nervous system alterations, alongside genetic, inflammatory, and psychological factors. Using data from TriNetX, this study investigated the impact of analgesic and adjuvant therapies on psychiatric outcomes in CRPS patients.
