    Summary
    This summary is machine-generated.

    This study introduces a novel design for randomized clinical trials, enabling private physicians to contribute without individual patient randomization. This approach enhances trial augmentation by assigning treatments at the physician level for consistent patient application.

    Area of Science:

    • Clinical Trials Methodology
    • Biostatistics
    • Public Health Research

    Background:

    • Traditional randomized clinical trials (RCTs) require individual patient randomization, which can be challenging in community settings.
    • Augmenting RCTs with real-world data from private practice can improve generalizability.

    Purpose of the Study:

    • To propose and evaluate a new design for augmenting randomized clinical trials using private physicians.
    • To facilitate the inclusion of private physicians in clinical research without requiring individual patient randomization.

    Main Methods:

    • A novel trial design where private physicians are randomized to study treatments.
    • Physicians consistently apply their assigned treatment to all eligible patients.
    • Development and description of a statistically rigorous analysis method for this design.

    Main Results:

    • Evaluation of the statistical efficiency of the proposed design.
    • Assessment of the feasibility and potential benefits of physician-level randomization.
    • Discussion of the limitations inherent in this trial augmentation strategy.

    Conclusions:

    • The proposed design offers a viable method for augmenting randomized clinical trials.
    • This approach may increase trial participation and data diversity by engaging private physicians.
    • Careful consideration of the design's limitations is necessary for appropriate application.
