Public Health Surveillance of Behavioral Health Emergencies through Emergency Medical Services Data
Abstract:
Objective: To identify the demographic, clinical and EMS characteristics of events documented as behavioral health emergencies (BHE) by EMS. Methods: This was a cross-sectional study using the 2018 National Emergency Medical Services Information System (NEMSIS) Version 3 dataset. All events that had patient care provided with a documented impression (field diagnosis) of ICD-10 codes F01-F99 (i.e., mental, behavioral, and neurodevelopmental disorders) were labeled a BHE and included. Descriptive statistics were calculated. Results: A total of 1,594,821 (7.3%) EMS calls had a BHE impression. The most common was mental and behavioral disorders due to psychoactive substance use (42.3%). More males than females had BHEs (54.6% vs. 45.4%), and most patients were ages 18-34 (31.5%). Most BHE occurred in urban settings (89.6%). Almost half (47.9%) were dispatched with a complaint unrelated to behavioral health. Conclusion: BHEs were noted in 7.3% of NEMSIS events, and the majority were associated with substance use disorders. EMS professionals need comprehensive training on best practices for BHE. Stakeholders should have information on prevalence of BHEs to ensure proper educational standards, training practices, and resource allocation.
