Objectives: Most US treatment and recovery services are abstinence-based. However, many people in recovery from an alcohol or other drug (AOD) use problem do not abstain completely. This study estimated the prevalence of and characteristics associated with nonabstinence among US adults in recovery.

Methods: Nonabstinence-operationalized as past-month use of alcohol, illicit drugs, or nonmedical use of prescription drugs-was estimated among a sample of 3763 US adults in self-identified recovery from the 2022 National Survey on Drug Use and Health, weighted to be nationally representative. Multivariable logistic regression identified factors associated with nonabstinence.

Results: An estimated 65.2% (95% confidence interval [CI] = 62.6-67.8) of adults in self-identified recovery reported past-month AOD use. Half (50.8%) reported alcohol use, and one-third (33.2%) reported cannabis use. Females had lower odds of use than males (adjusted odds ratio [AOR] = 0.73, 95% CI = 0.54-0.99), and lesbian/gay-identified individuals had greater odds of use than heterosexual/straight-identified individuals (AOR = 2.39, 95% CI = 1.13-5.07). Greater religiosity (AOR = 0.90, 0.84-0.96) and mutual aid attendance (AOR = 0.16, 95% CI = 0.06-0.27) were associated with lower odds of use. Significant differences were not detected for self-reported health, psychological distress, and other measures of functioning. However, relative to those without a past-year substance use disorder (SUD), odds of nonabstinence were greater among those with one mild (AOR = 14.60, 9.05-23.55), one moderate or severe (AOR = 13.05, 7.06-24.14), and multiple (AOR = 23.33, 10.59-51.37) past-year SUDs.

Conclusions: Most US adults who self-identified as in recovery from an AOD use problem were nonabstinent. Treatment and recovery services may improve engagement and outcomes by supporting nonabstinent goals.

Objectives: Assessment and counseling are recommended for individuals with prenatal cannabis use. We examined characteristics that predict prenatal substance use assessment and counseling among individuals who screened positive for prenatal cannabis use in prenatal settings.

Methods: Electronic health record data from Kaiser Permanente Northern California's Early Start perinatal substance use screening, assessment, and counseling program was used to identify individuals with ≥1 pregnancies positive for prenatal cannabis use. Outcomes included completion of a substance use assessment and among those assessed, attendance in Early Start counseling only or Addiction Medicine Recovery Services (AMRS) treatment. Predictors included demographics and past-year psychiatric and substance use disorder diagnoses evaluated with GEE multinomial logistic regression.

Results: The sample included 17,782 individuals with 20,398 pregnancies positive for cannabis use (1/2011-12/2021). Most pregnancies (80.3%) had an assessment. Individuals with Medicaid, anxiety, depression and tobacco use disorders, compared to those without, had higher odds and those with greater parity, older age (≥35) and in later trimesters, had lower odds of assessment. Among 64% (n = 10,469) pregnancies needing intervention based on assessment, most (88%) attended Early Start counseling only or AMRS (with or without Early Start). Greater parity and later trimester assessment was associated with lower odds, while Medicaid was associated with higher odds of Early Start counseling. Nearly all diagnosed psychiatric and substance use disorders were associated with higher odds of AMRS treatment.

Conclusions: A comprehensive prenatal substance use program engaged most pregnant individuals with prenatal cannabis use in substance use assessment and counseling. Opportunities to improve care gaps remain.

Background: In response to the opioid epidemic, federal agencies have stressed the importance of targeted naloxone distribution through avenues such as Opioid Overdose Education and Naloxone Distribution (OEND). OEND effectively reduces mortality by training laypersons to respond to overdose situations. Despite demonstrated effectiveness, OEND remains underutilized. This project aimed to characterize those who illicitly use opioids to determine avenues for future tailoring of OEND programs.

Methods: Individuals who illicitly used opioids within the past 6 months were recruited via online social media. Participants completed an online questionnaire that assessed history of opioid use and were given the option to receive opioid overdose and naloxone administration training. Those who elected training (n = 111) and those who declined (n = 193) were compared on opioid use, severity of use, and overdose experiences.

Results: Participants (N = 304) were 47% male and 83% White. Tests of between group differences with measures of effect size were used for analyses. Those who elected training endorsed greater intravenous administration (χ2 = 4.18, P = 0.041, Cramer's V = 0.12). Individuals who declined training reported more frequent nonprescribed methadone use (χ2 = 7.51, P = 0.006, Cramer's V = 0.16), overdose hospitalizations (t(298) = 2.13, P = 0.034, Cohen's d = 0.26), and observed overdoses (t(300) = 3.01, P = 0.003, Cohen's d = 0.36). After adjusting for multiple comparisons, only the differences in nonprescribed methadone use and observed overdoses remained statistically significant.

Conclusions: Individuals who declined training were more likely to report ever use of nonprescribed methadone and having witnessed others overdose. They may have had greater exposure to naloxone, hence decreasing perceived need for training. Understanding characteristics of those who elect and refuse training could inform structuring of programs and recruitment approaches.

Objective: Untreated opioid use disorder (OUD) is associated with significant morbidity in pregnancy. Recent reports have highlighted the rise of xylazine in the nonprescribed fentanyl supply. The frequency with which pregnant people with OUD are exposed to xylazine has not been characterized. We sought to describe the rate of xylazine detection in urine drug screens (UDS) from pregnant people admitted to a labor unit.

Methods: We performed a cross sectional study of all UDS results from an inpatient obstetric unit at an urban tertiary care center from December 2022, when xylazine was added to the detection panel, through July 2023. We perform universal verbal drug screening, with subsequent urine drug screening only performed after a positive verbal screen and consent. The trend of opioid-positive urine drug screens also positive for xylazine from December to July was measured with the Cochran-Armitage test.

Results: Of 5662 people admitted to Labor and Delivery during the study period, 138 UDS were sent for 123 unique individuals. Ninety-eight (71%) of UDS were positive for nonprescribed substances. Of positive UDS, 36 (37%) were positive for nonprescribed opioids, and of these, 17 (47.2%) were positive for xylazine among 14 pregnant people. The trend of UDS positive for opioids that were also positive for xylazine increased significantly over time (P = 0.030), from 0% in December 2022 to 100% in July 2023.

Conclusions: Over 8 months, xylazine positivity significantly increased in UDSs positive for nonprescribed opioids in an urban Midwestern hospital. These results underscore the critical need to study the impact of xylazine on obstetric outcomes.

Abstract: In recent years, there has been a marked surge in opioid overdose deaths among Black, Latino, and Native American populations. The emergency department (ED) represents a crucial opportunity to address these racial and ethnic inequities by initiating buprenorphine and providing referral for ongoing addiction treatment. Yet Black, Latino, and Native American populations encounter substantial inequities in ED-based addiction treatment access. Within this context, Koeber et al conducted their cross-sectional study of ED patients who screened positive for opioid misuse to evaluate inequities in buprenorphine administration. The authors found that Black ED patients were less likely (odds ratio, 0.56; 95% confidence interval, 0.35-0.88) to receive buprenorphine. There is an urgent need for mixed methods research to understand the drivers of these inequities and interventions to address the multilevel factors across the opioid use disorder care continuum to promote equitable, accessible, person-centered opioid use disorder treatment.

Abstract: More than 50 years of high-quality data demonstrate that naloxone is an efficacious and cost-effective overdose reversal agent. Intranasal naloxone is now available in the United States as an over-the-counter and generic medication for the first time since the start of the overdose crisis more than 20 years ago. As the overdose crisis continues to contribute to substantial loss of life, there is an historic opportunity for jurisdictions to expand equitable and sustained access to intranasal naloxone. Further, through simultaneously enacting and expanding effective Naloxone Access and Good Samaritan laws, and equitably implementing these laws, there is the potential to maximize the population-level effectiveness of naloxone to sustainably reduce overdose mortality.

Objectives: Inhalants are often used for their psychoactive effects, producing feelings of euphoria. Inhalant and solvent use is a serious public health concern, yet little is known about their effects on perinatal, fetal, and child outcomes. The aim of our review is to evaluate the impact of inhalant use by pregnant people on maternal, fetal, neonatal, and early childhood outcomes.

Methods: A systematic review was conducted on March 1, 2023, in 6 databases using relevant keywords. Bias assessment was performed using JBI Critical Appraisal Tools. Studies were included if they described a prenatal exposure to an inhalant; focused on maternal, fetal, neonatal, or early childhood outcomes; and were published as peer-reviewed reports in English.

Results: The search yielded 1101 unique references with 22 studies meeting eligibility criteria and representing 205 pregnancies and 171 infants.The most common symptom of inhalant use reported in pregnant people was altered mentation, followed by renal tubular acidosis (RTA) reported with toluene use. Most common fetal outcomes included fetal growth restriction and preterm delivery (<37 weeks), while neonatal outcomes were withdrawal symptoms, such as jitteriness, trouble feeding, and dystonia. Child outcomes included developmental delays, including cognitive and speech impairments, and postnatal growth restriction, including microcephaly.

Conclusion: Perinatal, fetal, and child outcomes associated with inhalant use among pregnant individuals are largely based on case reports and series. Prospective studies are needed to better characterize these outcomes, reduce stigma, increase equitable access to treatment, and identify potential interventions to reduce use and potential harm.

Background: Emergency department (ED)-initiated buprenorphine provides a low barrier access point and safety net to mitigate opioid overdose risk and increase treatment engagement. We sought to describe trends and patterns of buprenorphine utilization from the ED using national data.

Methods: This is a retrospective review of the National Hospital Ambulatory Medical Care Survey between 2014 and 2021. Our primary outcomes were trends in ED buprenorphine utilization. We described patient demographics, visit characteristics, and conducted trend analyses. We utilized logistic regression to determine predictors of buprenorphine prescribing.

Results: Between 2014 and 2021, there were 341,875 ED visits in which buprenorphine was administered, with no change over time (P = 0.08). There were 392,031 visits where buprenorphine was prescribed at ED discharge, with an increase over time (P = 0.01). The largest rise in rate for discharge prescriptions occurred between 2019 and 2020 (37,737 [0.03%] visits vs 126,041 [0.10%]) (233% increase in rate, P < 0.0001).

Conclusions: Although there was an increase in buprenorphine prescribing at ED discharge, there was no increase in administration. The acceleration in prescribing between 2019 and 2020 suggests that the ED may have been a safety net for patients who lost access to addiction care during COVID-19. Future studies should explore reasons for disparities and barriers to buprenorphine utilization.

Objective: This study aimed to describe initial experiences and lessons learned conducting a trial focused on recruiting racially and ethnically diverse hospitalized patients with untreated alcohol use disorder (AUD).

Methods: The parent trial is comparing the effectiveness of strategies including Brief Negotiation Interview (BNI), facilitated initiation of medications for AUD, and computer-based training for cognitive behavioral therapy (CBT4CBT) on AUD treatment engagement post-hospitalization. Guided by the Framework for Reporting Adaptations and Modifications-Enhanced, we catalogued protocol changes and evaluated outcomes using study and electronic medical record data during the first 18 months of recruitment.

Results: Recipients: (1) Selected entry criterion to intentionally include individuals most likely impacted by structural racism, (2) developed multipronged recruitment approaches, and (3) selected bilingual, multicultural, and ethnically diverse research staff. Intervention: (1) Added scripts in the BNI to consider how cultural factors influence and how racism may impact, alcohol use, and AUD treatment engagement, (2) offered tablets as a compensation alternative with support for CBT4CBT initiation (as relevant), and (3) anticipate and troubleshoot internet access challenges. Setting: (1) Identified community-based AUD treatment options with Spanish-speaking services and (2) identified resources to address social determinants of health. Study: (1) Audited data to monitor whether diverse enrollment is occurring. Among n = 132 randomized as of March 1, 2024, 25% endorsed Black, 24% endorsed Latine, 58% endorsed White, 1% endorsed Indigenous, and 15% endorsed race not listed or declined to disclose. We observed no difference by race or ethnicity in recruitment or retention experiences.

Conclusions: Multilevel practices within a hospital-based AUD-focused trial can promote recruitment and retention of a racially and ethnically diverse sample.

Objective: The aim of the study is to estimate the contributions of common and modifiable risk factors to birth outcomes of individuals with prenatal opioid use disorder (OUD).

Methods: We conducted an observational cohort study of all Wisconsin Medicaid-covered singleton live births from 2011-2019. Using Blinder-Oaxaca decomposition for continuous, and the Fairlie extension for categorical outcomes, we estimated the contributions of comorbidities, tobacco use, pre-pregnancy body mass index (BMI), and gestational weight gain (GWG) to birthweight for gestational age (BW-GA) percentile associated with prenatal OUD and the risk of small for gestational age (SGA), net of other factors.

Results: Among 216,684 births, the 5184 (2.4%) with OUD had greater prevalence of tobacco use, a lower average pre-pregnancy BMI (26.7 kg/m2, SD = 0.09 versus 28.4 kg/m2, SD = 0.02), and on average 2.0 pounds less GWG, when compared to those without OUD. The predicted mean BW-GA percentile among infants with OUD exposure was 11.2 (95% CI 10.5, 11.9) points lower than those without; 62.3% (95% CI 57.4, 67.1) of this difference could be explained by the variables included in the full model and the largest contribution of the explained portion came from the higher prevalence of tobacco use followed by the contributions of comorbidities, GWG, and pre-pregnancy BMI.

Conclusions: More than half of the difference in BW-GA percentile, and risk of SGA associated with prenatal OUD, could be attributed to modifiable factors and not opioids. Moreover, potentially modifiable factors including tobacco use and measures reflecting nutritional status contributed to a majority of the explained portion.
