Hospitals around the world need to be safe and prepared to face disasters, being these man-made or caused by natural hazards. The Hospital Safety Index (HSI) is a tool developed by the World Health Organization (WHO) that allows access to the level of preparedness of hospitals; it is the most widely used instrument of its kind. Although the HSI is frequently used by hospitals and healthcare facilities around the world, scientific literature on its application in real life is scarce and qualitative studies are absent. By adopting a qualitative methodology, this study aims to investigate the use of the HSI to assess disaster preparedness in hospitals and healthcare facilities, identify challenges and facilitators of the HSI use, and devise recommendations for future adaptations of the tool.

A retrospective qualitative study employing semi-structured online interviews was conducted to gather opinions and perspectives of professionals using the HSI to assess disaster preparedness. Participants were recruited by contacting via email the authors of scientific publications on the use of the HSI.

In total, nine people from three different countries (Serbia, Sri Lanka, and Indonesia) and having different professional backgrounds agreed to participate in this study. They shared the reasons for their choice of using the HSI, against other tools, as well as the steps taken before and during data collection. Strengths and weaknesses of the HSI were identified and authors reported the challenges they encountered in the preparatory phase and during data collection. Modifications of the tool and recommendations for the future were proposed targeting both researchers and hospital managers.

As far as the authors know, this is the first qualitative study examining the methodological implications of using the HSI and providing practical recommendations that can advance the HSI tool and foster its use for disaster preparedness assessments worldwide.
