1 Receipt of Medication Treatment after Nonfatal Overdose Among Emerging Adults
Sarah M. Bagley, MD, MSc Assistant Professor of Medicine and Pediatrics, BU SOM Director, CATALYST Program, Boston Medical Center AMERSA November 4, 2017

2 Emerging Adults Are Different
Emerging adulthood (18-25 years) is a distinct development stage Characterized by determining autonomy, figuring out self Emerging adults have high rates of alcohol and other drug use Emerging adults respond differently to attempts at treatment than adolescents and older adults

3 Heroin Use Is Significantly Increasing Among Emerging Adults

5 How are emerging adults experiencing the opioid overdose epidemic differently than older adults?
Describe characteristics of emerging adults (18-25 years) who experience a nonfatal opioid overdose in MA. Is there variation in receipt of medication treatment after nonfatal overdose based on age? Compare the time to addiction treatment and rates of receipt of treatment between emerging adults and older adults after nonfatal opioid overdose.

6 Methods Design. Retrospective cohort study of emerging adults who had a nonfatal overdose in Massachusetts between Study cohort. Individuals (ages 18-45) who had a nonfatal overdose between Entry was staggered and occurred when an individual had a nonfatal overdose. A nonfatal overdose was identified 2 ways 1) having an ambulance ride related to an overdose or 2) ED or hospital stay related to overdose.

7 Chapter 55 Authority This work was mandated by law, and conducted by a public health authority. All parties conducting and participating in this work did so on behalf of the Commonwealth of Massachusetts and the Massachusetts Department of Public Health.

8 Chapter 55: Phase 2 Data Structure
Chapter 55 Data Structure System Attributes… Linkage at individual level Longitudinal (5 year history) Data encrypted in transit & at rest Limited data sets unlinked at rest Linking and analytics “on the fly” No residual files after query completed Analysts can’t see data Automatic cell suppression MATRIS (EMS) APCD Spine Hospital and ED BSAS Treatment Medical Claims PDMP

9 Methods Primary outcome: time to addiction treatment (methadone, buprenorphine, or naltrexone) after first nonfatal overdose Other variables: age, gender, past year incarceration, past year involuntary commitment, psychiatric diagnoses, and past year medication treatment for opioid use disorder

10 Analysis Aim 1: Calculate summary statistics and chi-square analyses to describe characteristics of emerging adults who experience a nonfatal opioid-related overdose compared older adults Aim 2: Estimate Kaplan-Meier survival curves for emerging adults with a nonfatal overdose for time to treatment and fit Cox Proportional Hazards models to determine rates of treatment receipt

22 Limitations Individuals who experience overdose outside of health care system are not captured in these data. Only generalizable to MA

23 Conclusions Emerging adults represented nearly 1 in 5 non-fatal opioid-related overdoses among year olds in Massachusetts between Variation exists in receipt of medication by type of medication in 12 months following a nonfatal overdose 18-21 year olds are less likely to receive medication treatment including buprenorphine and methadone compered to older adults Emerging adults more likely to receive naltrexone than older adults Overall small proportions of individuals who experience a nonfatal overdose receive medication treatment in the following 12 month

24 Implications Future work should focus on outcomes (mortality, retention in treatment, and relapse) based on age and medication type There is a need for a better understanding of how (and why) emerging adults and providers make choices about medication treatment Post-overdose interventions to engage individuals in treatment after nonfatal overdose are urgently needed
