Physician-only anesthesia is not cost-effective. An anesthesia care team with a physician to certified registered nurse anesthetist (CRNA) ratio of 1:8 is cost-effective for low-risk patients, offering a better value than nurse-intensive models.

Area of Science:

  • Health Economics
  • Anesthesiology
  • Healthcare Management

Background:

  • Anesthesia workforce staffing significantly impacts healthcare costs and patient outcomes.
  • Optimizing the skill mix of physicians and certified registered nurse anesthetists (CRNAs) is crucial for efficient anesthesia delivery.
  • Previous studies have explored various staffing models, but cost-effectiveness analyses of different physician-to-CRNA ratios are essential.

Purpose of the Study:

  • To evaluate the incremental cost-effectiveness of different anesthesia workforce staffing scenarios.
  • To compare various skill mixes, including physician-intensive and nurse-intensive models, using decision analysis.
  • To identify the most cost-effective anesthesia care delivery system from a payer's perspective.

Main Methods:

  • A decision tree model was constructed to analyze five distinct anesthesia staffing scenarios.
  • Scenarios ranged from physician-only to nurse-intensive models, incorporating varying physician-to-CRNA ratios.
  • Cost-effectiveness was assessed by comparing incremental costs and outcomes across different staffing configurations.

Main Results:

  • Physician-only anesthesia staffing was found to be not cost-effective.
  • The "third-team" model, featuring a physician to CRNA ratio of 1:8 for low-risk patients, demonstrated cost-effectiveness compared to nurse-intensive models.
  • A physician to CRNA ratio of 1:2 was identified as the preferred staffing scenario for intermediate-risk patients.

Conclusions:

  • The "third-team" anesthesia staffing model offers a cost-effective approach, particularly for low-risk patient populations.
  • While medical direction of CRNAs for low-risk patients is cost-effective, increasing the physician to CRNA ratio beyond 1:8 may not provide justifiable incremental benefits.
  • Anesthesia care-team approaches, with optimized physician-to-CRNA ratios, represent a more cost-effective strategy than physician-only or purely nurse-intensive models.
