A Retrospective Cohort Study of Disparities in Urine Drug Testing During the Perinatal Period in an Urban, Academic Medical Center.

The purpose of this study was to evaluate disparities in urine drug testing (UDT) during perinatal care at a single academic medical center. This retrospective cohort study included patients who had a live birth and received prenatal care at our institution between 10/1/2015 and 9/30/2020. The primary outcomes were maternal UDT during pregnancy (UDTPN) and UDT only at delivery (UDTDEL). Secondary outcomes included the number of UDTs (UDTNUM) and the association between a positive UDT test result and race/ethnicity. Mixed model logistic regression and negative binomial regression with clustering based on prenatal care locations were used to control for confounders. Of 6,240 live births, 2,265 (36.3%) and 167 (2.7%) received UDTPN and UDTDEL, respectively. Black (OR 2.09, 95% CI 1.54-2.84) and individuals of Other races (OR 1.64, 95% CI 1.03-2.64) had greater odds of UDTPN compared to non-Hispanic White individuals. Black (beta = 1.12, p < 0.001) and Hispanic individuals (beta = 0.78, p < 0.001) also had a positive relationship with UDTNUM. Compared to individuals with non-Medicaid insurance, those insured by Medicaid had greater odds of UDTPN (OR 1.66, 95% CI 1.11-2.49) and had a positive relationship with UDTNUM (beta = 0.89, p < 0.001). No significant associations were found for UDTDEL and race/ethnicity. Despite receiving more UDT, Black individuals were not more likely to have a positive test result compared to non-Hispanic White individuals (OR 0.95, 95% CI 0.72-1.25). Our findings demonstrate persistent disparities in substance use testing during the perinatal period.

Evaluation of an injectable monthly extended-release buprenorphine program in a low-barrier specialty addiction medicine clinic.

INTRODUCTION: Monthly injectable extended-release buprenorphine (XR-BUP) can address several systemic and individual barriers to consistent sublingual buprenorphine treatment for patients with opioid use disorder (OUD). Real-world evaluations of XR-BUP in the outpatient addiction treatment setting are limited. The purpose of this study was to compare 6-month treatment retention and urine drug tests between patients who initiated XR-BUP compared to those who were prescribed but did not initiate XR-BUP in a low-barrier addiction medicine specialty clinic. METHODS: We conducted a retrospective cohort study of adults with OUD prescribed XR-BUP between 12/1/2018 and 12/31/2020 in a low-barrier addiction medicine specialty clinic to compare 6-month treatment retention between patients who initiated XR-BUP and those who were prescribed but did not initiate XR-BUP (comparison group). Secondary outcomes included percent of urine toxicology tests negative for non-prescribed opioids. Multivariable logistic regression models evaluated factors associated with 6-month treatment retention and XR-BUP initiation. RESULTS: Of the 233 patients prescribed XR-BUP, 148 (63.8 %) identified as non-Hispanic white, 218 (93.6 %) were insured by public insurance (Medicare/Medicaid), and nearly two-thirds were prescribed XR-BUP due to unstable OUD. Approximately 50 % of patients initiated XR-BUP treatment (mean number of injections = 3.7). About 60 % of XR-BUP-treated patients received supplemental sublingual buprenorphine and nearly two-thirds received a 300 mg maintenance dose. Six-month treatment retention was greater in the XR-BUP treatment versus comparison group (70.3 % vs. 36.5 %, p < 0.001). The XR-BUP treatment group had a higher percentage of opioid-negative urine toxicology tests versus the comparison group (67.2 % vs. 36.3 %, p < 0.001). Receipt of XR-BUP was an independent predictor of 6-month treatment retention (OR 5.40, 95 % CI 2.18-13.38). Those prescribed XR-BUP due to unstable OUD had lower odds of treatment retention (OR 0.41, 95 % CI 0.24-0.98) after controlling for receipt of XR-BUP and other variables known to impact retention. CONCLUSIONS: XR-BUP improved 6-month treatment retention and resulted in a greater proportion of opioid-negative urine toxicology tests compared to a comparison group of patients who were prescribed but did not initiate XR-BUP. Patients with unstable OUD had lower odds of XR-BUP initiation, suggesting the need for targeted interventions to increase XR-BUP uptake in this high-risk population.

Hospital-initiated Extended-release Injectable Buprenorphine Using a Novel Reallocation Initiative From an Outpatient Addiction Medicine Clinic.

OBJECTIVES: Novel strategies for initiation and continuation of buprenorphine are critical, especially during a pandemic when traditional opioid use disorder treatment pathways may be disrupted. We describe an innovative outpatient to inpatient reallocation initiative for extended-release buprenorphine (XR-BUP) designed to repurpose an expensive medication for use in hospitalized patients facing treatment barriers upon discharge and pilot the feasibility of XR-BUP use in the inpatient setting. METHODS: We collaborated with our institution's inpatient pharmacy and a New Jersey Medicaid managed care organization to create an alternate pathway to make XR-BUP available to hospitalized patients insured by the same payor. In this process, XR-BUP doses were deidentified and transferred to the inpatient controlled substance inventory for administration to hospitalized patients at no charge by our Addiction Medicine Consult Service after a period of sublingual buprenorphine stabilization. Our reallocation pathway bypassed several existing XR-BUP regulatory barriers to allow for inpatient administration. RESULTS: To date, we have transferred approximately 85 XR-BUP 300 mg doses to the inpatient controlled substance inventory. This equates to a cost savings of nearly $145,000. CONCLUSIONS: Reallocation of XR-BUP from an outpatient to inpatient setting increased postdischarge buprenorphine treatment access while also reducing health care costs by repurposing an expensive medication that would otherwise go to waste. Use of reallocated XR-BUP in the inpatient setting may pave the way for addition of XR-BUP to the hospital's formulary to minimize treatment gaps after discharge.

Attitudes on Methadone Utilization in the Emergency Department: A Physician Cross-sectional Study.

INTRODUCTION: Like buprenorphine, methadone is a life-saving medication that can be initiated in the emergency department (ED) to treat patients with an opioid use disorder (OUD). The purpose of this study was to better understand the attitudes of emergency physicians (EP) on offering methadone compared to buprenorphine to patients with OUD in the ED. METHODS: We distributed a perception survey to emergency physicians through a national professional network. RESULTS: In this study, the response rate was 18.4% (N = 141), with nearly 70% of the EPs having ordered either buprenorphine or methadone. 75% of EPs strongly or somewhat agreed that buprenorphine was an appropriate treatment for opioid withdrawal and craving, while only 28% agreed that methadone was an appropriate treatment. The perceived barriers to using buprenorphine and methadone in the ED were similar. CONCLUSION: It is essential to create interventions for EPs to overcome stigma and barriers to methadone initiation in the ED for patients with opioid use disorder. Doing so will offer additional opportunities and pathways for initiation of multiple effective medications for OUD in the ED. Subsequent outpatient treatment linkage may lead to improved treatment retention and decreased morbidity and mortality from ongoing use.

A Low-threshold Comprehensive Shared Medical Appointment Program for Perinatal Substance Use in an Underserved Population.

OBJECTIVES: We describe retention in care, medication for opioid use disorder (MOUD) prescribing, and urine toxicology outcomes of a comprehensive perinatal shared medical appointment model that combined medication, group-based counseling, and recovery supports. METHODS: We conducted a retrospective study of program retention between 11/1/16 and 3/31/20 in pregnant and postpartum women with substance dependence or use disorder. Disengagement reasons, MOUD prescribing, and urine toxicology were abstracted from medical records. A Cox proportional hazards model was used to evaluate risk factors for program disengagement. RESULTS: Approximately 87% of patients had OUD and 80% were pregnant at the initial visit (N = 140). Retention at 3 months, 6 months, 1 year, and 2 years was approximately 86%, 78%, 66%, and 48%, respectively. Over 97% of patients were prescribed MOUD and 88% of all urine toxicology results were negative for non-prescribed opioids. Patients enrolled after initiation of wraparound services (HR 0.52, 95% CI 0.28 - 0.96) and those attending more shared medical appointments (HR 0.90, 95% CI 0.87 - 0.93) had a lower hazard of disengagement after controlling for other covariates. Loss to follow-up was the most common disengagement reason. CONCLUSIONS: A low-threshold, comprehensive perinatal shared medical appointment program had high retention rates, increased access to evidence-based MOUD, and high rates of opioid-negative urine toxicology. Participants enrolled after wraparound services began had a lower hazard of disengagement. Future research in perinatal substance use should evaluate the most optimal and cost-effective components of comprehensive programs to inform standard of care.

Buprenorphine Field Initiation of ReScue Treatment by Emergency Medical Services (Bupe FIRST EMS): A Case Series.

The opioid epidemic is currently a leading health crisis in the United States, and evidence supports Medication for Opioid Use Disorder (MOUD) as the most effective treatment (2). In our EMS system we are observing an ever increasing number of patients who, due to refusing transport after naloxone rescue, represent an access void at the point of overdose. We present a case series to illustrate a new treatment paradigm utilizing front line EMS paramedic units and high dose buprenorphine to treat withdrawal symptoms with next day bridge to long term care. The three patients described are exemplary cases, meant to represent overall characteristics of the intervention prior to complete data collection. Each patient was revived from opioid overdose with naloxone. Paramedics then treated each patient with 16 mg of buprenorphine to relieve and prevent withdrawal symptoms. Patients were provided with outpatient follow up irrespective of ED transport. To the best of our knowledge, this is the first EMS agency in the United States providing MOUD in the prehospital setting at the point of overdose. This innovative program provides EMS with education and tools to promote patient engagement. While still in its infancy, this approach utilizes existing EMS resources to bring MOUD to the prehospital setting, offering a new avenue to long term care.
