Ecological disasters highlight the importance of understanding natural disasters as they relate to a changing global climate. Such disasters often have a predictable pattern of evolving over time and anticipated psychological and behavioral problems and community disruptions. Various factors enhance transmission of these adverse effects beyond the geographic location of the ecological disaster, with certain populations being particularly vulnerable to these effects. Understanding the range and pattern of these effects can aid in optimizing interventions. The use of evidence-informed interventions can reduce distress, enhance well-being, and improve functioning for affected individuals and communities. Effective preparedness involves an understanding of these factors, incorporation of them at all stages of disaster management, and continuous education and training for disaster planners and responders.

Many people exposed to climate-related or weather-related disasters experience stress and serious mental health consequences. Depending on the type of the disaster, these consequences include post-traumatic stress disorder (PTSD), depression, and general anxiety, which often occur at the same time [Very High Confidence]. The majority of affected people recover over time, although a significant proportion of exposed individuals develop chronic psychological dysfunction [High Confidence].

COVID-19 is a unique disaster, which has placed extreme stress on Healthcare Workers (HCWs) and the systems in which they work. Eradicating the pandemic requires sustainment of the healthcare workforce through actions that mitigate stress, promote resilience, and enhance performance. A major barrier is the lack of organizational practices and procedures designed to sustain HCWs during prolonged crisis events, such as COVID-19. Adapting existing best practices from other high-risk occupations allows for a more rapid, efficient response to optimize workforce well-being and preserve healthcare organizational functioning. This paper discusses current and emerging literature on the unique impacts of COVID-19 on HCWs and provides actionable, evidence-informed recommendations for individuals, teams, and leaders to enhance sustainment of HCWs that is critical to the preservation of national and global health security.
