Little is known about the characteristics of individuals using urgent care centers or walk-in retail clinics, collectively called convenience clinics (CC), as places of usual care. Using 2022 National Health Interview Survey data and logistic regression, we identified the factors associated with adults using CCs regularly. Among adults with a place of usual care, 7.5% reported receiving usual care at CCs. Individuals who were younger, working, and uninsured were significantly more likely to report CCs as their usual source of care. Understanding the characteristics of CC users is critical to inform policy for this evolving segment of the health care sector.
