Abstract
Nursing homes have long faced a shortage of direct care workers, a problem that was magnified during the COVID-19 pandemic. Using nationally representative data from three sources, we found that much of the certified nursing assistant (CNA) workforce in US nursing homes is filled by immigrant labor. The number of native-born CNAs has been declining rapidly since the mid-2010s, whereas the number of foreign-born CNAs has remained relatively constant. During the first two years of the COVID-19 pandemic, the share of immigrant CNAs employed by nursing homes surged, which can be explained by a simultaneous drop in the share of native-born staff. Staffing shortages observed during the pandemic would have been worse if not for foreign-born CNAs remaining in the workforce. However, the share of foreign-born CNAs varied considerably across states, from less than 1 percent in West Virginia to more than 70 percent in Hawaii. In an analysis of prepandemic data, we found that nursing homes in regions with a higher share of immigrant CNAs were associated with more direct care staff hours per resident day and better nursing home quality performance. With the growing demand for long-term care, creating pathways for job-seeking immigrants to fill the gaps in direct care will be crucial to meeting future staffing needs.
