“…Disturbance scenario analysis characterizes the type, severity, occurrence time, and potential risks. For healthcare facilities, the disturbances are classified into external disasters (e.g., earthquakes, large floods, epidemic, and war) and internal pressures (e.g., equipment failure and human error) ( 47 , 62 , 94 ). The external disasters will cause the healthcare facilities' internal structural failure directly or interrupt the supply of external lifeline services (e.g., electric, water, communication, and gas) for healthcare facilities.…”

In contemporary “high-risk” society, unexpected disasters (epidemics and extreme weather) and chronic pressures (aging problems) put tremendous pressure on healthcare facilities. Enhancing the healthcare facilities' resilience ability to resist, absorb, and respond to disaster disruptions is urgent. This study presents a scientometric review for healthcare facility resilience research. A total of 374 relevant articles published between 2000 and 2020, collected from Web of Science (WoS) core collection database, Scopus database and MEDLINE database were reviewed and analyzed. The results indicated that research on resilience in healthcare facilities went through three development periods, and the research involved countries or institutions that are relatively scattered. The studies have been focused on the subject categories of engineering, public, environmental, and occupational health. The keywords of “resilience,” “hospital,” “disaster,” “healthcare,” and “healthcare facility” had the most frequency. Furthermore, based on the literature co-citation networks and content analysis, the detected seven co-citation clusters were grouped into four knowledge domains: climate change impact, strengthening resilience in response to war and epidemic, resilience assessment of healthcare facility, and the applications of information system. Moreover, the timeline view of literature reflected the evolution of each domain. Finally, a knowledge map for resilience of healthcare facilities was put forward, in which critical research contents, current knowledge gaps, and future research work were discussed. This contribution will promote researchers and practitioners to detect the hot topics, fill the knowledge gaps, and extend the body of research on resilience of healthcare facilities.

“…The SRI is defined as the functionality of a structure after the recovery process or the ability of a structure to withstand earthquakes without any reduction in its functionality [31]. Also, the SRI can be treated as an alternative to deal with the problem of functionality which has been neglected in the seismic codes [32]. Therefore, the SRI is determined by referring to the functionality curves as shown in Figure 4.…”

Seismic resilience is a modern approach that aims to return the community of damage to its natural condition in a shortest possible time. Seismic resilience could be interpreted as a structure's ability to maintain a degree of functionality over a particular period of time once it is exposed to seismic events. The research study aims to address with an approach of functionality and seismic resilience of a mid-rise Ordinary Moment Resisting Frame (OMRF) structure subjected to repeated earthquakes. Besides, as a vulnerability and functionality study for risk assessments, both the Seismic Resilience Index (SRI) and the fragility surface were used to determine the seismic resilience of the selected building. The fragility surfaces expressed the probability of damages with respect to intensity measure and seismic event period (T). The concept phases of this approach were as follows: (1): Select targeted buildings, (2): Select and scaled a set of repeated Seismic Ground Motion (SGM) records, (3): Generate an Incremental Dynamic Analysis (IDA), (4): Fragility surface and (5): Functionality curve, with seismic resilience index (RI). Eventually, after investigating the structure through the vulnerability assessment, initiating with IDA, and ending with the fragility surface, it is clearly established that the buildings do not have the capacity to withstand a 15 sec repetitive earthquake due to their ordinary structural design related to ductility demand. Meanwhile, with an increase in the possible seismic ground acceleration, the fluctuation in functionality, SRI, robustness, structural losses, and time recovery of distinct performance levels could be estimated.

“…Jacques et al (2014) linked the losses in hospital population and resources and structure and equipment failures to the loss of key hospital functions, created a fault tree that represents the loss of hospital service functions, and proposed a quantitative method of hospital seismic resilience based on the results of the fault tree. Yu et al (2019) proposed a hospital seismic resilience assessment framework based on fault tree analysis. The fault tree considers the relationship between damaged non-structural components and the influence of external supply.…”

The post-earthquake functionality of hospital systems seriously affects the recovery time of a city, and it is important to quantify the hospital system functionality. This paper presents a method that takes into consideration the post-earthquake medical supply-demand relationship in order to quantify the initial functionality and instantaneous functionality loss of a hospital system under the conditions of an earthquake, which is different from the current quantitative method that takes into consideration only the internal factors of the hospital system. In this method, a geographic information system and an earthquake damage prediction model are first used to obtain the medical supply capacity before and after the earthquake and the medical demand after the earthquake. Based on the results of the post-earthquake medical demand and the distribution of the medical supply capacity, the substitution capacity of medical resources is then calculated. Finally, the substitution capacity of medical resources is used to evaluate the functionality of the hospital system before and after the earthquake. A hospital system of a city in eastern China is considered as an illustrative example, and the impact of changes in the medical supply and demand at different times of the day on the hospital system functionality are analyzed. The results obtained show that the changes in medical supply and demand not only affect the hospital system functionality, but also cause changes in the instantaneous functionality loss of the hospital system after the earthquake. The proposed method can be used to quantify the hospital system functionality and reflect the balance of the medical supply-demand relationship before and after the earthquake, and it can help decision makers in developing a disaster reduction strategy to improve the disaster resilience of the hospital system.
