BackgroundThroughout the past decades, the United States healthcare system has seen increased efforts to promote continuity of operations in response to external or internal stressors. There is no marker to characterize this facet of health system resilience. The two databases which may contain the most relevant data are the American Hospital Association (AHA) annual survey, which gathers over 1000 data points from more than 6000 hospitals, and the RAND corporation, which provides information on the financial health and viability of hospitals and health care systems. In that sense, AHA focuses more on organizational and practice issues, while RAND will cover more economic factors. Our study aimed to develop and psychometrically validate a new Hospital Resilience Index (HRI).MethodsWe took the AHA and RAND databases as primary data sources, and defined hospital closure as the main negative outcome indicating failed resilience. We performed descriptive statistics, and regression analysis of the databases.ResultsOur findings show that a combination of eleven variables is strongly associated with the likelihood of hospital closure. These factors mirror smaller hospital size, lack of ancillary functions, staffing structure of the hospital, size of facilities, number of surgeries performed, Medicare discharges, operating expenses, and medical school affiliation as a teaching hospital. We further classified hospitals with a low HRI (< 25) or high HRI (> 25). In this setup, we found that both hospitals with a low HRI and hospitals that would subsequently close were characterized by smaller patient census, smaller numbers of surgeries, fewer beds, a smaller staff, and a lower operating margin.ConclusionsTogether, these factors would point to a higher resilience to external stressors in larger, more expanded hospitals and healthcare systems, offering a broad range of services, and having a higher operating margin. The higher tiers of the healthcare system therefore seem to have more resilience, but the recent Covid-19 pandemic exhibited how much all tiers in the system are needed to respond to extraordinary crises such as pandemics or large natural disasters. Future research should seek to determine whether tracking the HRI over time may be a tool to identify hospitals at risk of closure.
