Longitudinal Outcomes of the top 20 Utilizers of VA Connecticut's Psychiatric Emergency Services Between 2010 and 2020.

Frequent utilizers of emergency services represent a clinically important cohort with potentially unmet health care needs despite demanding a high volume of costly services. However, not much is known about their longitudinal course. This study identified the top 20 utilizers of VA Connecticut's psychiatric emergency services and conducted a chart review of their longitudinal outcomes during an 11-year period between 2010 and 2020, including their visit diagnoses, medical and psychiatric comorbidities, and types and frequency of other medical services and supports received. At the index visit, 19 of the 20 patients had substance use disorder and 14 patients had at least one non-substance psychiatric diagnosis. Despite all patients receiving primary care and other services, such as residential treatments, outpatient therapy, and social work consults, 11 of the 12 patients remaining alive and residing in the state continued to utilize psychiatric emergency services in 2020, revealing a pattern of persistent use.
