A new patient classification system, Emergency Department Groups (EDGs), was developed for hospitals. This system effectively categorizes emergency department visits, explaining significant resource use variance for cost control.

Area of Science:

  • Health Services Research
  • Hospital Administration
  • Medical Informatics

Background:

  • Emergency departments face challenges in managing patient flow and resource allocation.
  • Accurate patient classification is crucial for effective hospital management and cost control.
  • Existing systems may not adequately capture the complexity of emergency department visits.

Purpose of the Study:

  • To develop and validate a patient classification system for hospital emergency departments.
  • To identify homogeneous patient groups based on clinical and resource utilization data.
  • To assess the system's utility for hospital cost control and reimbursement reform.

Main Methods:

  • Data collected from 20,000 patient records across three Los Angeles community hospitals.

  • Included medical records, billing information, and provider time data.
  • Patient visits classified into 216 groups (Emergency Department Groups - EDGs) using diagnoses, disposition, age, and procedures.

    • Main Results:

    • The developed Emergency Department Groups (EDGs) represent a clinically coherent classification system.
    • EDGs explained 63% of the variance in overall resource use (total direct cost).
    • The system demonstrated potential for improving hospital cost control.

    Conclusions:

    • The Emergency Department Groups (EDGs) provide a robust framework for classifying emergency department visits.
    • This classification system can be a valuable tool for hospital cost management.
    • EDGs may support future reimbursement reform initiatives.
