The Association Between Stimulant, Opioid, and Multiple Drug Use on Behavioral Health Care Utilization in a Safety-Net Health System
Abstract
Prior studies show an association between drug use and health care utilization.

We aimed to determine if multiple drug use was associated with increased utilization of behavioral health care. To assess health care utilization, we conducted a retrospective cohort study of patients who accessed health care at a safety-net medical center and affiliated clinics. Using electronic health records, we categorized patients who used stimulants, opioids, or multiple drugs based on urine toxicology screening tests and/or International Classification of Diseases, 9th Revision (ICD-9).

Utilization was described by rates of health care-related visits for inpatient, emergent/urgent, outpatient, and behavioral health care among patients who used drugs, categorized by drug types, compared with patients without identified drug use. Of 95,198 index visits, 4....Continue Reading
