Demographic and Geographic Trends in First-Episode Psychosis: A Cross-Sectional Study of Hospital Discharge Data in Adolescents and Young Adults.

Abstract

This cross-sectional study aimed to assess the demographic and geographic variations in the visit rate for first-episode psychosis (FEP), identify trends and diagnostic patterns, and explore factors associated with FEP visits in Nebraska. Inpatient and emergency department data spanning 2017-2021 were collected by the Nebraska Hospital Association (NHA). The study focused on Nebraska residents aged 14-35 admitted for FEP, identified through specific ICD-10 codes. The sample was derived using a multi-step process, and the data included patient demographics, Behavioral Health Regions, rural vs. urban residency, and neighborhood characteristics. Mann-Kendall tests were used to test for significant trends over time. T-tests and chi-squared tests were used to assess differences in each of the measures between patients with and without psychotic disorders. The study findings revealed a significant increase in visits related to psychotic disorders from 2017 to 2021. In 2021, the FEP visit rate was 116 per 100,000 individuals, varying considerably by age, gender, and Behavioral Health Region. Schizoaffective disorder bipolar type was the most frequent psychotic disorder. Patients with psychotic disorders tended to be older, predominantly male, and treated in acute care settings. The rising trend underlines the need for continued investment in early intervention programs and highlights challenges in rural areas, necessitating targeted interventions. The findings provide valuable insights to inform planning, advocate for funding, and address the specific needs of diverse populations. Future research should explore additional influencing factors and extend the study period to understand FEP trends comprehensively.
