Objectives: Direct care workers (DCWs) play a central role in supporting individuals' health and well-being across care settings, yet may face barriers to accessing health care themselves, particularly because of high rates of uninsurance.

Design: An observational study using pooled National Health Interview Survey (NHIS) data from 2014 to 2018.

Setting and Participants: The sample included survey respondents employed as direct care workers (DCWs), including hospital aides, home care workers, and nursing and residential care aides.

Methods: We used bivariate analyses to compare differences in health insurance coverage and health service use, defined in terms of access, utilization, and affordability, among DCWs by care setting. We then used stepwise multivariable logistic regression analyses to explore the associations between insurance coverage and health service use.

Results: The sample included 1499 DCWs. Compared with hospital aides, home care workers and nursing and residential care aides had lower insurance coverage rates, were more likely to rely on Medicaid, and reported lower health care utilization and higher cost barriers. Health insurance through Medicaid was associated with the highest odds of health care access and utilization and the lowest odds of cost barriers for DCWs.

Conclusions and Implications: Given the projected 9.3 million total job openings in the direct care workforce from 2021 to 2031, policy and practice interventions designed to support DCWs' health are essential for ensuring continuous and quality care for older adults and people with disabilities and serious illnesses.
