Identifying infection hotspots early on

Area of Science:

• Building Services Engineering
• Healthcare Facility Management
• Infection Control

Background:

• Ventilation and air-conditioning (HVAC) ductwork is frequently overlooked, despite its role in spreading airborne infections.
• Current inspection rates for HVAC systems in buildings are very low, with less than 5% of systems over 12 kW inspected, according to CIBSE.
• There is a critical need for improved methods to identify and manage potential infection pathways within healthcare facilities.

Purpose of the Study:

• To propose an integrated approach for enhanced identification and monitoring of infection hotspots in hospitals.
• To highlight the potential of combining 3D Building Information Modeling (BIM) with Computer-Aided Facilities Management (CAFM) systems.
• To address the risks associated with neglected HVAC systems in healthcare environments.

Main Methods:

• The study advocates for the integration of 3D BIM software with existing CAFM systems.
• This integration aims to create a comprehensive digital model of hospital infrastructure.
• The proposed system would enable rapid data analysis for identifying anomalies and potential infection risks within the ductwork.

Main Results:

• The integration of 3D BIM and CAFM systems offers a proactive solution for identifying 'infection hotspots'.
• This approach facilitates quicker detection and monitoring of areas with higher infection risks.
• Improved visibility and management of HVAC systems can lead to enhanced patient safety.

Conclusions:

• Neglected HVAC ductwork poses a significant, yet often ignored, risk for airborne infection transmission in hospitals.
• The proposed integration of 3D BIM and CAFM software presents a viable and efficient method for proactive infection control.
• Implementing this technology can significantly improve the identification, monitoring, and prevention of infection outbreaks in healthcare settings.
