Summary

Physician assistants (PAs) used fewer resources than residents in teaching hospitals for certain diagnoses. While PAs demonstrated comparable or superior resource utilization, higher mortality was observed in pneumonia cases managed by PAs.

Area of Science:

  • Healthcare Management
  • Medical Economics
  • Comparative Effectiveness Research

Background:

  • Resource utilization in healthcare settings is a critical factor in cost-effectiveness.
  • Understanding the comparative efficiency of different healthcare providers, such as physician assistants (PAs) and residents, is essential for optimizing patient care and resource allocation.
  • Teaching hospitals present unique environments for evaluating provider resource use due to structured training programs and diverse patient populations.

Purpose of the Study:

  • To compare the resource utilization of physician assistant (PA) services versus traditional resident teaching services.
  • To analyze resource use across five specific medical diagnostic groups within a community teaching hospital setting.
  • To control for the influence of attending physicians when comparing PA and resident services.

Main Methods:

  • A retrospective analysis of patient data from an internal medicine service in a community teaching hospital.
  • Inclusion of patients with stroke, pneumonia, acute myocardial infarction, congestive heart failure, and gastrointestinal hemorrhage.
  • Measurement of resource use via relative value units (RVUs) for laboratory, radiology, and total ancillary services, alongside length of stay (LOS).

Main Results:

  • Physician assistants (PAs) utilized fewer total ancillary resources for pneumonia patients and fewer laboratory resources for stroke, pneumonia, and congestive heart failure patients compared to residents.
  • No significant differences were found in average length of stay (LOS) or radiology resource use between PA and teaching services.
  • PAs did not use significantly more resources than residents in any category; however, a higher mortality rate was observed for pneumonia cases managed by PAs.

Conclusions:

  • Physician assistants (PAs) demonstrated resource utilization that was as effective as, or more effective than, residents in the same practice setting.
  • The findings suggest that PAs can be integrated effectively into teaching hospital services to manage resources efficiently.
  • Further investigation into the observed higher mortality in pneumonia cases managed by PAs is warranted.
