Area of Science:

  • Healthcare Management
  • Operations Research
  • Emergency Medicine

Background:

  • Emergency departments (EDs) face challenges with long patient waiting times.
  • Inefficient patient flow and resource allocation contribute to delays.
  • Effective management strategies are needed to optimize ED operations.

Purpose of the Study:

  • To investigate methods for reducing patient waiting times in the ED.
  • To identify specific interventions that can improve patient flow and service delivery.
  • To analyze the impact of staffing changes on ED waiting times.

Main Methods:

  • Collected arrival and service times for 663 patients across various ED stations.
  • Utilized SPSS for statistical analysis.
  • Employed simulation techniques to model patient flow and test intervention effectiveness.

Main Results:

  • The most significant reduction in waiting time was achieved by adding one intern to the Ear Nose Throat (ENT) service.
  • Average waiting time decreased from 112.19 minutes to 99.24 minutes with this intervention.
  • This suggests a potential improvement in ENT service efficiency.

Conclusions:

  • Optimizing staffing, particularly by adding specialized support like interns, can effectively reduce ED waiting times.
  • Healthcare managers in EDs may benefit from enhanced training in management principles.
  • Targeted interventions in specific services, like ENT, can yield measurable improvements in patient flow.
