A simulated model using UV tracer demonstrated contagion spread in an emergency department. Personal protective equipment (PPE) significantly reduced contamination, highlighting its importance in preventing healthcare-associated infections.

Area of Science:

  • Healthcare epidemiology
  • Infection control simulation
  • Medical emergency preparedness

Background:

  • Effective models for simulating contagion spread in emergency departments are lacking.
  • The impact of personal protective equipment (PPE) on reducing disease transmission in simulated healthcare settings remains unquantified.

Purpose of the Study:

  • To develop and validate a physical model for simulating the spread of an Ebola-like virus in an emergency department.
  • To quantify the effect of varying levels of PPE on reducing contagion transmission.

Main Methods:

  • A physical simulation model using computerized mannequins and a UV tracer (Glo Germ) to represent an Ebola-like virus was developed.
  • Contamination spread was assessed by UV fluorescence after simulated interactions between infected mannequins and healthcare providers with different PPE levels (masks and gloves only vs. full PPE).

  • Results were compared against a control group without tracer to account for background fluorescence.

    • Main Results:

    • Contagion spread to providers, other patients, and rooms, demonstrating the model's efficacy.
    • Providers with only masks and gloves (Group A) experienced 65 contaminations.
    • Providers with full PPE (Group C) had significantly fewer contaminations (3 with full PPE, 15 with partial PPE).

    Conclusions:

    • The UV tracer effectively simulated contaminated bodily fluid spread and demonstrated that barrier methods (PPE) reduce transmission.
    • The developed model is a valuable tool for evaluating PPE effectiveness and healthcare provider education strategies.
    • This simulation highlights the critical role of appropriate PPE in preventing healthcare-associated infections.
