The role of marijuana use disorder in predicting emergency department and inpatient encounters: A retrospective cohort study.

ABSTRACT:

Background

Marijuana use disorder (MUD) is the most common illegal drug use disorder and its prevalence is increasing. It is associated with psychiatric and medical problems, but little is known about its impact on emergency department (ED) and inpatient utilization rates.

Design

In a retrospective cohort design, we used electronic health record (EHR) data to identify patients with MUD (n=2752) and demographically matched patients without MUD (n=2752) in 2010. Logistic regressions determined risk of ED and inpatient visits each year from 2010 to 2014 for MUD patients versus controls; mixed-effect growth models examined differences in utilization rates over 5-years. Patient characteristics predicting increased risk of utilization were examined among the MUD sample only.
