Healthcare utilization due to suicide attempts among homeless youth in New York state

Suicide remains the leading cause of death among homeless youth. We assessed differences in healthcare utilization between homeless and non-homeless youth presenting to the emergency department or hospital after a suicide attempt. New York Statewide Inpatient and Emergency Department Databases (2009-2014) were used to identify homeless and non-homeless youth ages 10 to 17 who utilized healthcare services following a suicide attempt. To evaluate associations with homelessness, we used logistic regression models for mortality, use of violent means, intensive care unit utilization, log-transformed linear regression models for hospitalization cost, and negative binomial regression models for length of stay. All models were adjusted by individual characteristics with a hospital random effect and year fixed effect. We identified 18,026 suicide attempts with healthcare utilization rates of 347.2 (95% Confidence Interval [CI]: 317.5, 377.0) and 67.3 (95%CI: 66.3, 68.3) per 100,000 person-years for homeless and non-homeless youth, respectively. Length of stay for homeless youth was statistically longer than non-homeless youth (Incidence Rate Ratio 1.53; 95%CI: 1.32, 1.77). All homeless youth who visited the emergency department after a suicide attempt were subsequently hospitalized. This could suggest a higher acuity upon presentation among homeless youth compared with non-homeless youth. Interventions tailored to homeless youth should be developed.
