Millions of US adults continue to experience symptoms of post COVID-19 condition (PCC). More data on health service utilization patterns and barriers to care in this population are needed to understand how to care for people with PCC. To evaluate health service utilization and barriers to medical care among individuals with a history of PCC compared with other US adults. Data were analyzed from the 2022 National Health Interview Survey (NHIS), a nationally representative, cross-sectional survey of the US population. US adults. Health service utilization and the presence of financial and nonfinancial barriers to care in the preceding 12 months. There were 24,905 individuals included in the analysis, representing approximately 230 million US adults. The weighted prevalence of those with a history of PCC was 6.9% (95%CI, 6.5-7.3). Compared to other US adults, participants with a history of PCC were more likely to have had an urgent care visit (adjusted odds ratio (aOR) 1.52 [95%CI, 1.34-1.72]), emergency room visit (aOR 1.94 [95%CI 1.71-2.21]), hospitalization (aOR 1.48 [95%CI, 1.24-1.77]), rehabilitation services (aOR 1.35 [95%CI, 1.14-1.60]), home care (aOR 1.55 [95%CI, 1.66-2.26]), mental health counseling (aOR 1.39 [95%CI, 1.17-1.65]), and complementary and integrative medicine services (aOR 1.29 [95%CI, 1.13-1.49]). Furthermore, respondents with a history of PCC were more likely to report at least one financial barrier to care (aOR 1.71 [95%CI, 1.48-1.97]) and at least one nonfinancial barrier (aOR 1.77 [95%CI, 1.56-2.00]). A greater proportion of participants with a history of PCC reported a financial barrier and nonfinancial barrier than adults with most other chronic conditions captured by NHIS. Individuals with a history of PCC were more likely to use a variety of health services and report barriers to medical care. Health systems should consider developing accessible, multidisciplinary care pathways for this population.
