Disasters and pandemics adversely affect long-term care residents in many ways. While these catastrophic events increase staff stress and strain, they also negatively impact residents’ family members and close informal caregivers. When social distancing and personal protective equipment are needed to control disease outbreaks, both interventions decrease positive human interactions for this already vulnerable population. Disaster preparedness and response activities designed to mitigate the increased risk of morbidity, mortality, and hospitalizations, such as evacuating to a safe shelter, can often trigger the very outcomes they are trying to prevent. Moreover, there is a growing recognition that multiple threats frequently occur simultaneously or sequentially, with differing and competing responses required for each. In a living environment where trauma-informed care (TIC) was already required, the pandemic and recent disasters highlight the importance of assessing previous trauma exposure and current symptomology. Identifying potential trauma triggers for residents can inform disaster and pandemic planning and enhance residents’ well-being. Although the immediate impacts of pandemics and disasters can be severe, the enduring effects on the emotional and behavioral health functioning of residents living in long-term care continue to be a significant public health concern. This chapter provides an overview of how pandemics and disasters influence residents’ behavioral health functioning, describes the provision of behavioral health services, and shares lessons learned that can be applied now and in the future. Adaption of service delivery via telehealth, trauma-informed care, and psychological first aid will be discussed.
