Topic Collection: Disasters and At-Risk Populations
Accessing healthcare may be a challenge to at-risk populations across the U.S. The rate of disasters has increased over the years and the COVID-19 pandemic affected communities of color, rural communities, and other underserved populations especially hard. Healthcare professionals and emergency managers may benefit from a better understanding of the complex relationships that affect fair access to healthcare.
Healthy People 2030 lists five domains of social determinants of health: economic stability, education access and quality, healthcare access and quality, neighborhood and built environment, and social and community context.
The resources in this Topic Collection highlight these considerations and lessons learned from a variety of natural and human-caused disasters and provide guidance for healthcare practitioners who are committed to improving at-risk populations’ access to healthcare.
Stakeholders may also wish to access the Populations with Access and Functional Needs and Rural Disaster Health Topic Collections.
Each resource in this Topic Collection is placed into one or more of the following categories (click on the category name to be taken directly to that set of resources). Resources marked with an asterisk (*) appear in more than one category.

Using land-parcel and census tract socio-economic data, the authors examine the relationship between social inequalities and climate change-related (specifically due to Hurricane Harvey) extreme weather event effects. They found that Latina/x/o neighborhoods--specifically those that were low-income and located outside of FEMA’s 100-year floodplain--were disproportionately affected. They emphasize the need to address the impact climate change is already disproportionately having on certain populations in addition to planning for future events.

Behavioral Risk Factor Surveillance System survey respondent data was examined to determine the relationship between race/ethnicity (independent variable) and disaster preparedness (three dependent variables). The authors found that people from racial/ethnic minority groups were less likely to have three days’ worth of medical supplies. Only Spanish-speaking Hispanics were less likely to have an emergency evacuation plan than white respondents.

The authors advocate for the expansion of surge capacity plans to meet the chronic health care needs of vulnerable populations that increase following the acute phase of disaster response. They use a health services model to identify factors that perpetuate health disparities following disasters. To address these disparities, the authors recommend a baseline assessment of needs, with the expectation that such health care needs will expand post-disaster.
