Abstract Background The COVID-19 pandemic has intensified pressure on healthcare organizations (HCOs), particularly long-term care organizations (LTCOs. An HCO’s resilience is closely linked to its proactive ability to address and manage both novel and persistent stressors. This proactive approach, termed ‘preventive resilience,’ involves preemptively averting stressors to safeguard the organization’s resilience mechanisms. Objectives The aim of this presentation is to examine the hypothesis asserting that preventive resilience is, to a significant extent, nurtured by the collective capacity of a Long-Term Care Organization (LTCO) to act and react as a cohesive social system. This collective agency capacity of an LTCO is posited to play a pivotal role in fortifying preventive resilience of HCOs. Methods We conducted a pooled cross-sectional study on long-term care organizations in Germany during the initial (April 2020) and subsequent waves of the pandemic (December 2020-January 2021). Our sample comprised 503 leaders during the first wave and 294 leaders during the second wave from various long-term care organizations. The study involved top managers of these facilities reporting their perceptions of the collective agency capacity of the LTCO, assessed using the AGIL short scale. Additionally, they were asked to gauge the facility’s exposure to both general non-pandemic demands and pandemic-specific demands. Results We discovered a notable inverse relationship between leaders’ perceptions of the collective agency capacity within their Long-Term Care Organizations (LTCO) and their assessments of general demands. However, no significant association was observed between the agency capacity and the magnitude of pandemic-specific demands. Conclusions The findings tentatively endorse the notion that cultivating the collective agency capacity of nursing facilities enhances their resilience to familiar general demands, particularly during periods of exceptional stress. Key messages • Cultivating the collective agency capacity of nursing facilities enhances their resilience to familiar general demands. • The collective capacity to act and react in a cohesive way is a general resistance resource of healthcare organizations.
