Area of Science:

  • Emergency Medicine
  • Health Services Research
  • Public Health

Background:

  • Frequent emergency department (ED) use is a significant concern in healthcare systems.
  • Understanding the temporal patterns of ED utilization among frequent users is crucial for resource allocation and intervention development.

Purpose of the Study:

  • To investigate the longitudinal patterns of emergency department (ED) use among a cohort of frequent ED users.
  • To identify factors influencing changes in ED utilization over time.

Main Methods:

  • Retrospective study of adult patients with >10 visits to a university hospital ED within a 1-year period.
  • Follow-up of ED visits for this cohort across all metropolitan hospitals for 3 years.
  • Review of medical records to determine the etiology of ED visits.

Main Results:

  • The cohort comprised 76 patients with 1,119 ED visits (1.9% of total).
  • 46% were frequent users in only the initial year; 17% were frequent users across all 4 years.
  • Medical problems accounted for the majority of visits in 55% of patients; psychiatric or substance abuse issues were prevalent in 58% of persistent frequent users.

Conclusions:

  • The pattern of ED use among frequent users is dynamic and changes over time.
  • Psychiatric and substance abuse problems significantly influence ED utilization patterns.
  • Most patients identified as frequent ED users do not remain so consistently over extended periods.
