Clinical Scorecard: Patterns and Hospital Influences on Patients Departing from Emergency Departments Without Consultation, 2015-2024

At a Glance

CategoryDetail
ConditionPatients Leaving Without Being Seen (LWBS)
Key MechanismsED crowding, hospital characteristics, and systemic healthcare strains
Target PopulationPatients visiting emergency departments in California
Care SettingEmergency Departments in nonfederal general acute care hospitals

Key Highlights

  • Overall LWBS rates decreased from 2.8% in 2015 to 2.2% in 2020, then increased to 3.4% in 2022 before decreasing to 2.6% in 2024.
  • LWBS rates were significantly higher at urban (2.6%) vs rural (2.1%) hospitals.
  • Government-owned hospitals had higher LWBS rates (3.9%) compared to for-profit hospitals (2.4%).
  • Safety net hospitals exhibited higher LWBS rates (3.3%) compared to non-safety net hospitals (2.3%).
  • Disparities in LWBS rates may impair equitable emergency care access.

Guideline-Based Recommendations

Diagnosis

  • Monitor LWBS rates as an indicator of ED crowding and healthcare system performance.

Management

  • Address systemic strains contributing to ED crowding to reduce LWBS rates.

Monitoring & Follow-up

  • Utilize hospital characteristics (ownership, trauma center status) to assess LWBS performance.

Risks

  • Increased LWBS rates may lead to adverse health outcomes due to delayed care.

Patient & Prescribing Data

Patients presenting to emergency departments in California

Consider hospital characteristics when evaluating LWBS rates and access to care.

Clinical Best Practices

  • Implement strategies to reduce ED crowding and improve patient flow.
  • Regularly review and analyze LWBS data to identify trends and disparities.
  • Engage in community outreach to address barriers faced by underserved populations.
