Summary

This review covers engineering controls, including ventilation and germicidal irradiation, to prevent tuberculosis spread in healthcare settings. It also details controls for high-risk medical procedures to minimize TB transmission.

Area of Science:

Public Health
Infectious Disease Control
Occupational Safety

Background:

Tuberculosis (TB) remains a significant global health threat, particularly in healthcare settings.
Effective infection control strategies are crucial to prevent nosocomial transmission of TB.
Existing literature highlights the need for comprehensive reviews of engineering controls for TB prevention.

Purpose of the Study:

To review and synthesize current knowledge on engineering controls for preventing tuberculosis transmission in healthcare environments.
To provide an overview of ventilation strategies, including supplementary technologies like HEPA filtration and UVGI.
To specifically address engineering controls relevant to high-risk medical procedures associated with increased TB transmission potential.

Main Methods:

Systematic literature review of engineering controls for TB infection prevention.
Analysis of ventilation systems, high-efficiency particulate air (HEPA) filtration, and ultraviolet germicidal irradiation (UVGI).
Examination of controls for aerosol-generating procedures (AGPs) in healthcare.

Main Results:

Ventilation, HEPA filtration, and UVGI are key engineering controls for reducing airborne TB bacilli.
Specific modifications to ventilation and air cleaning are effective during AGPs.
Proper implementation of these controls can significantly lower the risk of TB transmission.

Conclusions:

Engineering controls are fundamental to a multi-faceted approach to TB infection control in healthcare.
Optimizing ventilation and air disinfection is essential for patient and healthcare worker safety.
Further research and implementation of advanced engineering controls are recommended for robust TB prevention programs.
