OBJECTIVE: To identify the environmental factors essential for infection control in senior-living facilities. BACKGROUND: In the COVID-19 pandemic, older adults are more likely to be infected and develop serious outcomes than young people. Worldwide, senior-living facilities face a battle to protect their residents. Compared with age-related declines, the built environment is more modifiable and can be used for infection control. METHODS: This research conducted content analysis of the guidelines on COVID-19 control issued by the State Council of China in February 2020 for senior-living facilities. Six senior-living facility managers in China were interviewed and shared their experiences using these guidelines. Quantitative and qualitative analyses were conducted to identify the essential environmental factors for infection control. RESULTS: Environmental factors suggested in the guidelines were analyzed for three groups of infection-control strategies: keep COVID-19 from entering the facility, prevent COVID-19 spread in the facility, and manage infection and illness. Key topics of experience using the guidelines were identified, including residents' needs for social interaction and the difficulties of providing dedicated air-conditioning and circulation systems. Based on these analyses, from the perspective of environmental design, environmental factors essential for COVID-19 control in senior-living facilities were summarized at the site, building, and room levels. CONCLUSION: Proper planning and design of the built environment promote strategies for infection control in senior-living facilities. Findings can be used to guide the new design, renovation, and modification of senior-living facilities for COVID-19 control and future public health emergencies.
