Analysis of veterans crisis line data: Temporal factors associated with the initiation of emergency dispatches

Abstract

AbstractPurposeTo identify temporal patterns of emergency dispatches as initiated by Veteran Crisis Line (VCL) responders and among moderate‐ and high‐risk contacts.MethodsIncidence rate ratios (IRRs) were used to examine the incidence of emergency dispatches among all 1,437,543 VCL contacts across 2019–2020.ResultsEmergency dispatches were initiated in 57,077 (4.0%) contacts. IRRs were elevated during Labor Day, IRR (95% CI) = 1.33 (1.15–1.54), and Independence Day, IRR (95% CI) = 1.22 (1.05–1.43), weekends, Saturdays, IRR (95% CI) = 1.04 (1.01–1.08), Sunday (reference), and 6 pm to 11:59 pm, IRR (95% CI) = 1.06 (1.04–1.09). IRRs for moderate‐ and high‐risk contacts were higher on Memorial Day, IRR (95% CI) = 1.16 (1.00–1.33), Sunday (reference), and 6 pm to 11:59 pm (reference).ConclusionsThe initiation of emergency dispatches fluctuates over time and were highest during Labor Day and Independence Day, weekends, and evenings. Moderate‐ and high‐risk contact also fluctuate over time and were highest on Memorial Day, Sundays, and midnight to 5:59 am. VCL policy makers can use knowledge of temporal fluctuations to allocate public health resources for increased efficiency and greatest impact; however, additional research on temporal stability and generalizability is needed.
