Psychiatric Hospitalization Associated with Emergency Department Visits

Abstract

Psychiatric boarding in an emergency department (ED) has personal and social consequences that can increase healthcare expenditure through a variety of inter-related mechanisms. This study aimed to compare health outcomes (e.g., length of stays, the severity of illness) between patients who stayed in an emergency department and those who did not visit an emergency department before the hospitalization. With the National Inpatient Sample dataset in the United States, we compared psychiatric inpatient service utilization outcomes between those who had stated in an emergency department and those who had not. Results: Among those with ED visits, the in-hospital mortality was 0.80 times lower (95% CI: 0.79-0.81). The length of hospital stays and the total charges were not significantly different from those without ED visits. The integration of primary care with psychiatric inpatient services can improve the management of psychiatric prevention and treatment, with the reduction of ED visits. This study provides an essential value in reducing emergency visits as the plan for psychiatric inpatient utilization to achieve more cost-effective and adequate healthcare outcomes.
