Design Criteria of Shelter Hospitals in Response to Biological Accidents: A Systematic Review

Background The appropriate response to mass causality biological events requires well-established preparedness and providing a surge capacity. In such a situation, a practical solution is to convert large public venues into shelter hospitals. Due to the lack of a guideline for the transformation of a large public center into a hospital, the present study collected the design criteria for the transformation of public buildings into shelter hospitals in response to biological events such as epidemics or mass causality biological accidents. Methods The keywords were searched in Scopus, Web of Science, and PubMed databases until November 2021. This systematic review was conducted using terms related to mass causality biological accidents, shelter hospitals, and design criteria. Results Of 1802 extracted articles, duplicates (n = 280) and unrelated publications (n = 1342) were left out in the initial evaluation. Among 180 remained papers, 29 records satisfied our criteria after reviewing abstracts and full texts. Most of the included studies were related to the transformation of public venues into hospitals in response to the coronavirus disease 2019 (COVID-19) pandemic. The investigated themes included site selection, layout and structure, waste and wastewater management, ventilation, communication, food and medicine delivery, humanitarians and social supports, post-treatment care, and Management measures. Conclusions In summary, large public venues are highly recommended alternatives for surge capacity in response to mass causality biological accidents. However, the main challenges for using these centers are the provision of basic requirements such as water and electricity, ventilation, and available space.
