A new relative risk index for hospitals exposed to tsunami
A new relative risk index for hospitals exposed to tsunami
The failure of hospitals in recent tsunami have caused extensive social and economiclosses. A simple but quantitative approach is required to assess the resilience of healthcaresystems to tsunami, which relates not only to hospital building integrity, but also tomaintaining hospital functionality. This paper proposes a new tsunami relative risk index(TRRI) that quantifies the impact of tsunami on critical units, (e.g. Intensive Care Unit,Maternity Ward, etc) in individual hospitals, as well as the impact on service provisionacross a network of hospitals. A survey form is specifically developed for collecting of fielddata on hospitals for the TRRI evaluation. In its current form TRRI is designed for hospitalbuildings of reinforced concrete construction, as these are the building types mostcommonly used worldwide for housing critical units. The TRRI is demonstratedthrough an application to three hospitals located along the southern coast of SriLanka. The TRRI is evaluated for three potential tsunami inundation events and isshown to be able to identify issues with both the building and functional aspects ofhospital critical units. Three “what-if” intervention scenarios are presented and their effecton the TRRI is assessed. Through this exercise, it is shown that the TRRI can be used bydecision makers to simply explore the effectiveness of individual and combinedinterventions in improving the tsunami resilience of healthcare provision across thehospital system.

Abstract
The failure of hospitals in recent tsunami have caused extensive social and economiclosses. A simple but quantitative approach is required to assess the resilience of healthcaresystems to tsunami, which relates not only to hospital building integrity, but also tomaintaining hospital functionality. This paper proposes a new tsunami relative risk index(TRRI) that quantifies the impact of tsunami on critical units, (e.g. Intensive Care Unit,Maternity Ward, etc) in individual hospitals, as well as the impact on service provisionacross a network of hospitals. A survey form is specifically developed for collecting of fielddata on hospitals for the TRRI evaluation. In its current form TRRI is designed for hospitalbuildings of reinforced concrete construction, as these are the building types mostcommonly used worldwide for housing critical units. The TRRI is demonstratedthrough an application to three hospitals located along the southern coast of SriLanka. The TRRI is evaluated for three potential tsunami inundation events and isshown to be able to identify issues with both the building and functional aspects ofhospital critical units. Three “what-if” intervention scenarios are presented and their effecton the TRRI is assessed. Through this exercise, it is shown that the TRRI can be used bydecision makers to simply explore the effectiveness of individual and combinedinterventions in improving the tsunami resilience of healthcare provision across thehospital system.
