The prospective association between illicit drug use and nonprescription opioid use among vulnerable adolescents

Underage Alcohol Use by Intersectional Identity Among Alternative High School Students

PURPOSE

To examine alcohol use (AU) among intersectional subgroups within a longitudinal cohort of predominantly Hispanic/Latino alternative high school (AHS) students in southern California.

METHODS

Past month AU was measured over a period of three years among 1,029 students (mean age 17.5 years, 49.7% female, 76.1% Hispanic/Latino) from 29 AHSs. Multilevel models that adjusted for age, socioeconomic status, parental education, weekly income, sensation seeking, depression, anxiety, and stress estimated trends in AU over time among intersectional subgroups defined by gender, ethnicity, and generational immigration.

RESULTS

Students with parents born in the United States had high rates of AU at the baseline that remained stable over time. In contrast, first-generation Hispanic/Latino students had lower levels of AU at the baseline that increased over time. First-generation, female, Hispanic/Latino students exhibited one of the lowest probabilities of AU at the baseline (28.6%, confidence interval [CI]: 15.9%-41.3%) but at the two-year follow-up had one of the highest probabilities (47.4%, CI: 29.3%-65.5%). A similar trend was observed among first-generation, male, Hispanic/Latino students whose probability of past month AU rose between the baseline (23.1%, CI: 12.4%-33.8%) and two-year follow-up (36.0%, CI: 19.2%-52.7%).

DISCUSSION

Findings underscore the heterogeneity of AHS students, showing a more nuanced picture of AU by the intersection of gender, ethnicity, and generational immigration. Underage AU prevention efforts among AHS students must provide targeted messages to intersectional identities.

Positive Toxicology Results Are Not Associated with Emergency Physicians' Opioid Prescribing Behavior

Introduction

Given the general lack of literature on opioid and naloxone prescribing guidelines for patients with substance use disorder, we aimed to explore how a physician’s behavior and prescribing habits are altered by knowledge of the patient’s concomitant use of psychotropic compounds as evident on urine and serum toxicology screens.

Methods

We conducted a retrospective chart review study at a tertiary, academic, Level I trauma center between November 2017–October 2018 that included 358 patients who were discharged from the emergency department (ED) with a diagnosis of fracture, dislocation, or amputation and received an opioid prescription upon discharge. We extracted urine and serum toxicology results, number and amount of prescription opioids upon discharge, and the presence of a naloxone script.

Results

The study population was divided into five subgroups that included the following: negative urine and serum toxicology screen; depressants; stimulants; mixed; and no toxicology screens. When comparing the 103 patients in which toxicology screens were obtained to the 255 patients without toxicology screens, we found no statistically significant differences in the total prescribed morphine milligram equivalent (75.0 and 75.0, respectively) or in the number of pills prescribed (15.0 and 13.5, respectively). Notably, none of the 103 patients who had toxicology screens were prescribed naloxone upon discharge.

Conclusion

Our study found no association between positive urine toxicology results for psychotropically active substances and the rates of opioid prescribing within a single-center, academic ED. Notably, none of the 103 patients who had toxicology screens were prescribed naloxone upon discharge. More research on the associations between illicit drug use, opioids, and naloxone prescriptions is necessary to help establish guidelines for high-risk patients.
