An Initiative to Reduce Ambulance Offload Delays in an Australian Emergency Department-A Time Series Analysis

Area of Science:

• Emergency Medicine
• Healthcare Operations Management
• Quality Improvement Science

Background:

• Ambulance offload delays are a critical issue, leading to adverse patient outcomes and reduced emergency medical services (EMS) availability.
• Inefficient offload processes strain hospital resources and impact community access to timely emergency care.

Purpose of the Study:

• To quantify the impact of a targeted intervention designed to reduce ambulance offload times.
• To assess improvements in patient flow and EMS resource utilization through a streamlined offload process.

Main Methods:

• An improvement initiative implemented in November 2024, featuring streamlined offload criteria, immediate physician consultation, and expedited treatment room access.
• Dynamic regression analysis was employed to evaluate the intervention's effect on offload times post-implementation.
• The intervention's commencement date was standardized as November 1, 2024, for consistent analysis.

Main Results:

• The study analyzed 187,301 patient presentations, with 55,802 (29.8%) arriving by ambulance.
• Prior to the intervention, 39.7% of patients were offloaded within the 40-minute benchmark.
• The intervention correlated with a statistically significant 16.4% increase in ambulance patients offloaded within 40 minutes (p < 0.0001).

Conclusions:

• Granting triage personnel defined offload criteria and prompt physician access enhances the rate of timely ambulance patient offloads.
• This intervention demonstrates a successful strategy for improving emergency department efficiency and patient flow.
• Optimizing ambulance offload processes is crucial for enhancing overall emergency medical system performance.
