This study introduces a new statistical framework for evaluating the cost-effectiveness of competing interventions. It proposes novel cost-effectiveness (c-e) measures and statistical methods for ranking interventions, aiding healthcare decision-making.

Area of Science:

  • Health Economics
  • Biostatistics
  • Clinical Trial Analysis

Background:

  • Evaluating competing interventions requires robust statistical methods for cost and effect data.
  • Existing cost-effectiveness (c-e) measures may not fully capture patient-level cost-effect relationships.

Purpose of the Study:

  • To present a statistical framework for analyzing cost and effect data from RCTs or observational studies.
  • To propose novel c-e measures that utilize patient-level cost-effect linkages.
  • To provide statistical techniques for assessing intervention admissibility, equality, and ranking.

Main Methods:

  • Utilizing parameters of the joint distribution of costs and effects or a regression function.
  • Developing new c-e measures based on patient-level cost-effect relationships.

  • Implementing a two-stage statistical procedure for intervention assessment and ranking.

    • Main Results:

    • New c-e measures are proposed, offering different perspectives and potentially altering intervention rankings.
    • Statistical techniques are provided for confidence intervals, hypothesis testing (admissibility, equality), and intervention ranking.
    • The framework is illustrated using a hypothetical clinical trial of antipsychotic agents.

    Conclusions:

    • The proposed statistical framework and novel c-e measures enhance the evaluation of competing interventions.
    • The methods facilitate statistically sound decision-making in healthcare by providing robust intervention rankings.
    • This approach improves the statistical rigor in health economic evaluations, particularly in clinical settings.
