Understanding how health organisations respond to crises, particularly in comparison to previous studies, is crucial for identifying gaps in resilience and resource allocation strategies. This research aims to analyse the reactions of health organisations to crises, with a focus on the recent coronavirus disease (COVID-19) pandemic. This pandemic has impacted the health sector, more specifically institutions caring for the elderly. Hence, it is important to study how resources are valued and how organisations react to crises. To this end, a longitudinal study was carried out, between 2015 and 2020, within a health institution, considering two key stages: the budget restrictions imposed by the French State (the non-health crisis) and the COVID-19 pandemic (the health crisis). Results from this research show that healthcare supply chain resilience during Stage 1 only concerned the strategic level, while Stage 2 affected all hierarchical levels. Consequently, non-strategic resources became strategic resources. This study also shows that building a collective capacity for healthcare supply chain resilience improves well-being at work among health workers.
