Episode-based efficiency comparisons for physicians and nurse practitioners
Medical Care
|February 1, 1982
Summary
Nurse practitioners offer a cost-effective alternative to physicians for common pediatric conditions. Their care per episode is 20% cheaper and equally effective, challenging doubts about new health practitioner cost-savings.
Area of Science:
- Health Services Research
- Comparative Effectiveness Research
- Healthcare Economics
Background:
- Previous studies on healthcare provider efficiency often used patient visits as the primary metric.
- The healthcare episode is recognized as a more accurate, though methodologically complex, unit for assessing efficiency.
Purpose of the Study:
- To compare the efficiency of nurse practitioners (NPs) and physicians using an episode-based methodology.
- To evaluate the cost-effectiveness and patient-reported outcomes of NP-led care versus physician-led care.
Main Methods:
- Utilized data from the Columbia Medical Plan information system and direct provider time observations.
- Focused analysis on care episodes for otitis media and sore throat within a pediatric department.
- Employed an episode-based approach to measure provider efficiency and costs.
Main Results:
- Episodes initiated by NPs were approximately 20% less costly than those initiated by physicians.
- Patient-reported effectiveness data suggested NP care was not less effective than physician care.
- Findings support the cost-saving potential of NPs in group practice settings.
Conclusions:
- Episode-based efficiency comparisons reveal significant cost advantages for nurse practitioners.
- Nurse practitioner care demonstrates comparable effectiveness to physician care for selected pediatric conditions.
- This study provides evidence for the economic benefits of integrating NPs into healthcare delivery systems.
