Characterizing and combating the opioid epidemic in the Los Angeles County jail system.

Introduction: Opioid overdose-related morbidity and mortality is a pressing public health crisis. Successful overdose reversal through bystander administration of naloxone is well documented, but there is an absence of literature on the implementation and impact of widespread naloxone access in a correctional setting during incarceration. The objective of this study was to describe our efforts to combat opioid overdose, prevent deaths, and examine and identify opioid use and predictors of opioid use through factors including age, sex assigned at birth, and ethnicity among the incarcerated population within the Los Angeles County jail system.

Methods: We retrospectively analyzed self-reported substance use information from all newly incarcerated persons from September 2018 to December 2020 to characterize opioid use in the Los Angeles County Jail system and used multivariable logistic regression analysis to determine predictors of substance use. We analyzed data on all cases of naloxone administration by custody personnel (i.e., all correctional officers) during the same period by examining patient demographic information, hospital discharge diagnosis, and patient outcome information. To describe naloxone training and access for incarcerated persons as an overdose prevention strategy, we reviewed electronic health record data on patient health outcomes for all cases of naloxone administration by an incarcerated person.

Results: A total of 6.4 % (11,881 of 187,528) of incarcerated persons reported opioid use. In the multivariable analysis, reported substance use was most significantly associated with any ethnicity other than Black (aOR for White =11.2; 95 % CI 10.4, 12.0, aOR for Hispanic/Latinx 3.0; 95 % CI 2.8, 3.2, aOR for All Others; 5.2 95 % CI 4.6, 5.8) and being <65 years old. Naloxone was administered by custody personnel to a total of 129 patients, where 122 (94.6 %) survived and 7 (5.4 %) died. After the deployment of naloxone in jail housing units, there were two instances of bystander naloxone administration by incarcerated persons that led to successful opioid overdose reversal and survival.

Conclusions: The expansion of naloxone availability to both custody personnel and incarcerated persons is an effective and warranted method to ensure timely naloxone administration and successful overdose reversal in a correctional setting.
