Place-Based Disparities Among Nursing Homes During the COVID-19 Pandemic: A Systematic Literature Review.

Introduction: Disasters have disproportionately impacted nursing home (NH) residents. COVID-19 impacted NH more so than the community-dwelling population, but there was much variation in mortality rates among NH residents. These disparities have been studied, but place-based disparities have received less attention. Place-based disparities are differences in health due to physical location, including factors like rurality, local socioeconomic conditions, and the physical environment. Methods: We searched three databases for peer-reviewed studies of place-based factors associated with mortality in U.S. NHs during the COVID-19 pandemic, ending in January 2024. Data were organized using the National Institute on Minority Health and Health Disparities research framework. Results: We identified 27 articles that included individual, interpersonal, community, and societal place-based factors associated with mortality during the pandemic. Differences in mortality were related to local community socioeconomic factors, staff neighborhood socioeconomic factors, urbanity, community viral spread, and state-level factors, including political leaning and social distancing policies. Rurality was associated with lower mortality but was also associated with racial disparities. Discussion: Place-based disparities at the individual, organizational, community, and societal levels were identified. Rurality and local COVID-19 spread were the most commonly studied place-based factors associated with NH deaths during the pandemic. Neighborhood factors may be most impactful through the impact on NH staff. Racial disparities were linked with location, highlighting the effects of historical systemic racism on NHs. Policies to protect NH residents during disasters must be sensitive to local characteristics.
