Objectives: As buprenorphine treatment and illicit buprenorphine use increase, many patients seeking buprenorphine treatment will have had prior experience with buprenorphine. Little evidence is available to guide optimal treatment strategies for patients with prior buprenorphine experience. We examined whether prior buprenorphine experience was associated with treatment retention and opioid use. We also explored whether type of prior buprenorphine use (prescribed or illicit use) was associated with these treatment outcomes.
Methods: We analyzed interview and medical record data from a longitudinal cohort study of 87 individuals who initiated office-based buprenorphine treatment. We examined associations between prior buprenorphine experience and 6-month treatment retention using logistic regression models, and prior buprenorphine experience and any self-reported opioid use at 1, 3, and 6 months using nonlinear mixed models.
Results: Most (57.4%) participants reported prior buprenorphine experience; of these, 40% used prescribed buprenorphine and 60% illicit buprenorphine only. Compared with buprenorphine-naïve participants, those with prior buprenorphine experience had better treatment retention (adjusted odds ratio [AOR] = 2.65, 95% CI = 1.05-6.70). Similar associations that did not reach significance were found when exploring prescribed and illicit buprenorphine use. There was no difference in opioid use when comparing participants with prior buprenorphine experience with those who were buprenorphine-naive (AOR = 1.33, 95% CI = 0.38-4.65). Although not significant, qualitatively different results were found when exploring opioid use by type of prior buprenorphine use (prescribed buprenorphine vs buprenorphine-naïve, AOR = 2.20, 95% CI = 0.58-8.26; illicit buprenorphine vs buprenorphine-naïve, AOR = 0.47, 95% CI = 0.07-3.46).
Conclusions: Prior buprenorphine experience was common and associated with better retention. Understanding how prior buprenorphine experience affects treatment outcomes has important clinical and public health implications.

Introduction: Missouri's Medication First ("MedFirst") approach promotes same-day and long-term low-threshold access to medications for opioid use disorder (MOUD). Since 2017, Missouri's SAMHSA-funded State Targeted and State Opioid Response (STR/SOR) grants have supported MedFirst services (both medical and psychosocial) for uninsured individuals with opioid use disorder at state-contracted treatment programs. Though MedFirst demonstrated early success, results - with attention to possible racial disparities - must be revisited after five years of implementation.

Question: The opioid epidemic causes massive morbidity, and males have substantially greater overdose mortality rates than females. It is unclear whether there are sex-related disparities at different stages in the trajectory of opioid use disorders (OUD), from large samples in the community.
Goal: To determine sex disparities in non-medical opioid use (NMOU) at the end of treatment with medications for opioid use disorder (MOUD), using national data.

Buprenorphine has superior safety in opioid use disorder compared with alternatives due to its action as a partial opioid agonist, which limits its ability to cause respiratory depression. There is a risk of precipitated opioid withdrawal after buprenorphine exposure in someone using full opioid agonists. Buprenorphine induction strategies that avoid precipitated withdrawal remain a crucial component for starting buprenorphine in individuals actively using opioids.

Objectives: Opioid use disorder (OUD) remains a common cause of overdose and mortality in the United States. Emergency medical services (EMS) clinicians often interact with patients with OUD, including during or shortly after an overdose. The aim of this study was to describe the characteristics and outcomes of patients receiving prehospital buprenorphine for the treatment of opioid withdrawal in an urban EMS system.

Resting-state functional connectivity analyses have been used to examine synchrony in neural networks in substance use disorders (SUDs), with the default mode network (DMN) one of the most studied. Prior research has generally found less DMN synchrony during use and greater synchrony during cessation, although little research has utilized this method with opioid use. This study examined resting brain activity in treatment-seeking persons who use opioids at two points-when using opioids and when opioid-free-to determine whether the DMN exhibits different levels of connectivity during opioid use and cessation and whether differences in connectivity predict subsequent relapse.
