## Abstract

PROJECT SUMMARY
This Diversity Supplement is designed to support and enhance the diversity of the health-related research
workforce through the training of Sarah Clingan, PhD., a Latinx/Native American Addiction Researcher. The
supplement is complementary to the parent grant, an R01 on overdose and opioid use disorder in Los Angeles
County, funded under the National Institutes of Health's Helping End Addiction Long-Term Initiative. Dr.
Clingan has a strong research background in addiction sciences that will continue to develop under the
mentorship of Dr. Chelsea Shover (primary mentor, epidemiologist, and MPI of parent grant), Dr. Steve
Shoptaw (senior co-mentor) a licensed psychologist and Director of the Center for Behavioral and Addiction
Medicine at UCLA, and Dr. David Goodman-Meza (co-mentor, physician-scientist, and MPI of parent grant).
These three mentors have a strong record of collaboration and a track record of mentoring underrepresented
scholars. Through this supplement, Dr. Clingan will obtain training and mentorship across three training
objectives. The first will focus on gaining skills and experience using natural language processing (NLP) and
machine learning approaches. She will additionally gain skills in designing research projects using real-world
data to study polysubstance use. Her third and final training objective is professional development activities
that will culminate in her writing a K01 career development award, using the findings generated by the Diversity
Supplement as pilot data. The research component of the Diversity Supplement will use electronic health
record (EHR) data collected via the parent grant to identify people with polysubstance use and create models
of healthcare utilization among those who co-use opioids and stimulants. Specifically, the aims of the Diversity
Supplement research plan are to: 1) develop an algorithm to identify people with polysubstance use (opioids
and stimulants) in EHR data; 2) Characterize healthcare utilization among those who co-use opioids and
stimulants using NLP-based approaches. These results will improve our understanding of polysubstance use in
a county with a very high burden of overdose involving fentanyl and stimulants, and contribute to our
understanding of the gaps in healthcare services for this population in Los Angeles County. The Diversity
Supplement findings will also provide preliminary data for Dr. Clingan's planned K01 application. This award
will provide Dr. Clingan with the support, mentorship, and protected time that will enhance her training at UCLA
and facilitate her transition to become an independent researcher.
