Costs and outcomes for different primary care providers.

Area of Science:

• Health economics
• Ambulatory care
• Medical education

Background:

• Assessing healthcare costs is crucial for resource allocation.
• Understanding cost variations across different provider types is essential for efficient healthcare delivery.
• The impact of provider training level on treatment costs in ambulatory settings requires further investigation.

Purpose of the Study:

• To investigate the relationship between medical training levels and direct medical costs.
• To compare costs associated with acute illness episodes treated by faculty, residents, and physician assistants.
• To identify cost drivers and their correlation with patient outcomes.

Main Methods:

• Retrospective analysis of 1,700 acute illness episodes in ambulatory-care clinics.
• Categorization of providers into faculty, family practice residents (by year), and physician assistants.
• Examination of total costs and component costs (laboratory, medication, etc.).
• Definition of a 'good outcome' as a return to usual functioning.

Main Results:

• No significant difference in average total cost per episode based on provider type.
• Significant differences (P < .05) in laboratory and medication costs among provider types.
• Faculty and physician assistants incurred higher costs, especially for patients with poor outcomes.
• No significant differences in costs or good outcome rates among first-, second-, and third-year residents.

Conclusions:

• Provider type influences specific cost components (laboratory, medication) rather than overall direct costs in ambulatory acute care.
• Higher costs associated with faculty and physician assistants may be linked to patient outcomes.
• Medical training level, within residency years, did not demonstrably impact cost-effectiveness or patient outcomes in this cohort.
