COVID-19 in Long-Term Care: The Built Environment Impact on Infection Control
1Design Consultant, Self-Employed, Victoria, British Columbia, Canada.
Purpose:
The purpose of this article is to review available literature for evidence-based impact of the built environment upon the prevention and management of COVID-19 with a view to emphasizing lessons learned for future infection control of pandemics.
Background:
This is urgently needed given the devastation brought upon long-term care residents worldwide. Long-term care (LTC) facilities face a battle to protect their residents. Previous studies of infection control design issues have focused generally on Fomites: that is, contaminated objects and surfaces. As COVID-19 has been shown to be largely spread through the air, this article will broaden the focus to include engineering controls that effect this type of transmission.
Method:
A literature search was conducted using key words such as long-term care facilities, built environment, COVID-19, infection control, and nursing homes.
Results:
Results were sorted using an engineering controls pyramid developed by the author to stratify approaches to LTC infrastructure. Basically, six elements were supported: ventilation, spatial separation, physical barriers, hand hygiene stations, resident room zones, and private rooms.
Implications:
Conclusions were that the built environment has a major impact on infection control that can be deleterious or beneficial. Substantial changes need to be made to protect the very vulnerable LTC population from future pandemics and infectious diseases.
