Background: The article describes the potential use of an original model called the layered epidemiological assessment (warstwowa ocena epidemiologiczna – WOE) for assessing the potential risk of infections in facilities intended for elderly individuals. Material and Methods: To verify the possibility of using the WOE method for assessing epidemiological safety hazards in the built environment, available literature sources related to the legal requirements in Poland regarding the assessment of medical facility ergonomics in terms of infection transmission were analyzed. The article also referred to the guidelines of the New European Bauhaus and the Baukultur Quality System as a standardized method for assessing the quality of the built environment. The article presents the fundamental assumption of the author’s WOE method, which allows for the assessment of the risk of infection transmission separately for each component of a building. The effectiveness of the method was demonstrated by using it to assess the risk of infections in a geriatric ward room as an example. Results: The article demonstrates that by employing the WOE, it is possible to clearly differentiate potential infection routes within the analyzed facilities and assign them to specific building components. Furthermore, by applying the presented method, it is possible to define necessary procedures and develop action plans to minimize the risk of infection spread within the analyzed properties. Conclusions: The application of the WOE for evaluating architectural solutions in facilities intended for the elderly offers several benefits. The WOE method presented in the article can serve as an expert tool for quick and precise assessment of potential epidemiological hazards. An important advantage of the WOE method is its ability to be used separately for different types of epidemiological hazards characterized by different routes of infection transmission.
