OBJECTIVE: Extended release buprenorphine injection (INJ-BUP) has been available in the United States since 2018. INJ-BUP has the potential to positively impact opioid use disorder (OUD) treatment outcomes by providing additional treatment options . As one of the largest payers of OUD treatment in the US, Medicaid coverage is important for access and uptake of INJ-BUP. Uptake of INJ-BUP among Medicaid beneficiaries has not been described since 2019 and variation in uptake by state has not previously been explored. We aimed to measure prescribing of INJ-BUP for Medicaid beneficiaries since 2018, nationwide and by state.
METHODS: We analyzed State Drug Utilization Data from 2017 to 2022 and calculated the number of prescription fills for INJ-BUP and oral buprenorphine paid by Medicaid. To compare across states, we calculated the number of prescription fills per 100 Medicaid beneficiaries treated for OUD using data from Transformed Medicaid Statistical Information System Substance Use Disorder (T-MSIS SUD) Data Books. Data sources are publicly available.
RESULTS: The number of prescription fills for INJ-BUP paid by Medicaid increased from 4322 (0.1% of all buprenorphine prescription fills) in 2018 to 186 861 (2.0%) in 2022. Each year the increase in fills exceeded the prior year change, indicating accelerating uptake. There was notable variability across states.
CONCLUSIONS: The number of extended release buprenorphine injection prescriptions among US Medicaid beneficiaries treated for opioid use disorder increased from over 4000 prescriptions in 2018 to over 185 000 in 2022 but uptake is much less than observed in other countries over shorter time periods.

Buprenorphine is an effective and safe treatment for opioid use disorder, but the requirement for moderate opioid withdrawal symptoms to emerge prior to initiation is a significant treatment barrier.
We report on two cases of hospitalized patients with severe, active opioid use disorder, in which we initiated treatment with transdermal buprenorphine over 48 h, followed by the administration of a single dose of sublingual buprenorphine/naloxone and then extended-release subcutaneous buprenorphine. The patients did not experience precipitated withdrawal and only had mild withdrawal symptoms.
This provides preliminary evidence for a rapid induction strategy that may improve tolerability, caregiver burden, and treatment retention as compared to previous induction strategies.

Opioid use disorder (OUD) continues to be a major public health crisis, with the current epidemic being driven by synthetic opioids such as illicitly manufactured fentanyl. While medications exist to treat OUD, only sublingual and subdermal buprenorphine formulations are approved for patients aged 16-17 years. Furthermore, almost all pediatric patients who are diagnosed with OUD do not receive medication as treatment. This case describes the innovative use of buprenorphine extended-release subcutaneous injection in a 17-year-old with OUD who has achieved early remission after four months of treatment. This case supports the use of buprenorphine extended-release in pediatric patients who are at high risk. While buprenorphine extended-release injections are not Food and Drug Administration-approved for pediatric patients, the increase in adolescent overdose deaths and lack of access to treatment in this age group support the need for increased research and treatment options for youth with OUD.

According to the Centers for Disease Control and Prevention (CDC), 100,306 drug overdose deaths occurred in the US during a 12-month period ending in April 2021. Opioids were involved in 75% of these related deaths. Opioid Use Disorder (OUD) is a constantly evolving public health crisis with potentially lethal consequences. In 2017, 900 adolescents began to misuse opioids every day. Nearly 10% of high school seniors reported using opioids nonmedically. Additionally, the incidence for hospitalizations for adolescents among children 1-19 years of age increased nearly 2-fold from 1997 to 2012. This data emphasizes the dangers associated with the increasing accessibility of pharmaceutical and non-pharmaceutical opioids, particularly for adolescents. All three of the currently FDA approved medications for OUD have shown clear efficacy in decreasing all-cause mortality in adults. It is proposed that the same effects should be seen in adolescents but limited data is present. A recent study analyzed buprenorphine and naltrexone treatment amongst OUD in adolescents between 2001-2014; only 1 in 4 youth received any medication therapy within six months of diagnosis. Adolescents under 16 were the most likely to receive medications. However, even adolescents aged 17, for whom buprenorphine is FDA approved for, were less likely to receive therapy than adults over 18 years of age. The following case report aims to demonstrate how subcutaneous extended release buprenorphine treatment can be initiated effectively as an outpatient in an adolescent with OUD. It is critical that clinicians work to expand access to pharmacotherapy for adolescents struggling with OUD to ensure proper management and reduction of opioid-related overdoses.

Extended-release (ER) monthly injectable buprenorphine offers an alternative to daily sublingual (SL) dosing for treatment of opioid use disorder (OUD) that may be attractive to several patient populations, including those with barriers to adherence and the frequent follow-up that are necessary for traditional SL buprenorphine. Despite the potential benefits of ER-buprenorphine, there are significant barriers to healthcare provider adoption that may prevent utilization in the populations that would benefit.
Our health system began providing clinic-administered ER-buprenorphine as treatment for OUD in May 2018 at a single clinic. Expansion was limited due to difficulties with delayed and inaccurate medication delivery and heavy administrative burden. To facilitate uptake of ER-buprenorphine for patients who could benefit, our integrated health-system specialty pharmacy (HSSP) assumed responsibility for medication distribution and administrative management beginning in October 2019. The HSSP provided accurate medication delivery, alleviated administrative burdens of benefits investigation and Risk Evaluation and Mitigation Strategy compliance, and decreased medication wastage by implementing a medication return process. Subsequently, ER-buprenorphine services were expanded to 4 additional sites, allowing 244 more patients to receive treatment.
HSSP support can provide significant benefit to patients and the health system through coordinating ER-buprenorphine dispensing and delivery.

In clinical trial settings, extended-release buprenorphine (XR-BUP) is noninferior to sublingual buprenorphine and may offer some advantages. However, real-world experiences of XR-BUP are limited and outcomes are unknown for low-threshold clinics with high-risk populations. Practical guidance is lacking on overcoming treatment challenges, such as inability for some to stabilize on sublingual (SL) BUP for seven days prior to XR-BUP and ongoing craving/withdrawal symptoms during treatment.
Retrospective case series of a convenience sample of 40 serial adults with opioid use disorder (OUD) treated with XR-BUP from Massachusetts General Hospital bridge clinic from February 1, 2019, to July 31, 2019.
Patients were mostly male (67.5%), non-Hispanic white (97.5%), unstably housed (77.5%), and average age of 32.1 years old. The average SL BUP dose prior to XR-BUP was 18.6 mg (standard deviation [SD] = 5; range 8-32) for an average treatment duration of 105 days (SD = 191; range 1-810). Ten (25%) patients received SL BUP for fewer than the seven recommended days (mean = 3.7, SD = 1.4, range = 1-6). Standard induction dosing was administered to 30%, empiric high-dose XR-BUP (300 mg monthly) was administered to 25%, and 55% were treated with supplemental SL BUP ranging from 4 to24mg, daily or as needed, for varying time periods. At the end of data collection, 65% remained on XR-BUP, 30% discontinued XR-BUP, and one patient was lost to follow-up. Acute care utilization rates were similar between patients who continued XR-BUP versus discontinued at 18.5% and 16.6%, respectively (χ2 = 0.02, p-value = 0.89). Toxicology was negative for other opioids in 65% of patients throughout treatment. There were no reports of overdose, withdrawal after use of opioids, or precipitated withdrawal after subsequent XR-BUP. Patients\' most cited reason for discontinuing XR-BUP was a preference for SL BUP.
This real-world evaluation of XR-BUP in a low-threshold clinic found that treatment was feasible, well tolerated, and outcomes were good, with most individuals choosing to continue treatment and a majority with no evidence of ongoing opioid use or precipitated withdrawal.

UNASSIGNED: Many psychiatric, long-acting injectable (LAI) medications are available, and each product comes with its own unique challenges. Improper administration can lead to pain, decreased efficacy, and loss of trust in the patient-provider relationship. This study was conducted to determine if a pharmacist-led, 1-hour training was successful in increasing psychiatric LAI medication knowledge through a pretest and posttest. The study also assessed staff satisfaction, confidence, and relevance to practice through a feedback questionnaire.
UNASSIGNED: Four 1-hour live trainings took place in November 2019. Thirty-five nurses and 8 medical assistants attended 1 of the trainings. A pretest and posttest was administered to determine the training\'s efficacy, and then a final assessment was administered 4 to 6 weeks after the training. Additionally, a participant feedback questionnaire was given to determine the perceived benefits of the training.
UNASSIGNED: The primary outcome was to compare pretest and posttest scores. The pretest average score was 67%, the posttest average score was 97%, and the average score 4 to 6 weeks after the training was 97%. The secondary outcome was to review feedback questionnaires to determine the perceived benefit and effectiveness of the training. Ninety-five percent of participants selected that they were very satisfied with the training, 88% selected they would definitely use the information presented in their work, and 93% selected that they had a lot of confidence in the topic after the training.
UNASSIGNED: A psychiatric LAI medication training administered to nursing staff and medical assistants improved knowledge scores and was perceived as being useful.
