Advancing resilience of critical health infrastructures to cascading impacts of water supply outages—Insights from a systematic literature review

Abstract

The current understanding of critical health infrastructure resilience is still dominated by a technical perspective. Reality however is different, as past events including the COVID-19 pandemic have revealed: emergency situations are only rarely exclusively technical in nature. Instead they are a product of prior circumstances, often linked to natural hazards, technical mishaps, and insufficient social and organizational preparedness structures. However, experiences and lessons learned from past events are still largely overlooked and have not sufficiently found their way into conceptual understandings of critical health infrastructure resilience. This paper addresses this gap by challenging the one-sided and technically oriented understanding of resilience in the context of critical health infrastructure. Based on a systematic literature review, it assesses real-world cases of water supply failures in healthcare facilities, a serious threat largely overlooked in research and policy. The results underscore the need for targeted organizational strategies to deal with cascading impacts. The overall findings show that addressing technical aspects alone is not sufficient to increase the overall resilience of healthcare facilities. Broadening the dominant resilience understanding is hence an important foundation for healthcare infrastructures to improve risk management and emergency preparedness strategies to increase their resilience towards future disruptions.
