Poorer patients, particularly those paying out-of-pocket or in rural areas, are more likely to see physician assistants (PAs) than physicians. This highlights the role of PAs in serving underserved populations.

Area of Science:

  • Health Services Research
  • Medical Economics
  • Public Health

Background:

  • Rising healthcare costs and access barriers necessitate innovative healthcare delivery models.
  • The physician assistant (PA) profession was established to improve access to care, especially for underserved populations.
  • Understanding patient demographics and insurance status is crucial for optimizing healthcare resource allocation.

Purpose of the Study:

  • To investigate the hypothesis that patients with lower socioeconomic status are more likely to receive care from physician assistants (PAs) compared to physicians in outpatient settings.
  • To analyze the relationship between patient financial status, geographic location, and the likelihood of seeing a PA versus a physician.

Main Methods:

  • Retrospective analysis of National Ambulatory Medical Care Survey data from 1997-2003.

  • Inclusion of outpatient physician and office staff data.
  • Weighted logistic regression analysis to adjust for patient and visit characteristics.

    • Main Results:

    • Patients with Medicare insurance had lower odds of seeing PAs compared to those with private insurance (OR: 0.48).
    • Patients paying out-of-pocket had higher odds of seeing PAs compared to privately insured patients (OR: 1.37).
    • Patients in rural areas were more likely to see PAs than urban patients (OR: 2.02).

    Conclusions:

    • Physician assistants are significantly utilized across various healthcare settings.
    • PAs play a vital role in providing care to underserved populations, including those in rural areas and lacking health insurance.
    • Findings underscore the importance of PAs in addressing healthcare access disparities.
