Editorial Policy And Review Methodology

Citation methodology

• Prefer original validation studies for scoring systems and prediction tools.
• Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
• Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.

Review workflow

• Confirm the calculator name, inputs, intended population, and clinical use case.
• Compare interpretation and limitations against the cited validation literature or current guidance.
• Check that calculator output remains educational and does not read as diagnosis, treatment, or individualized medical advice.
• Update the visible last-reviewed date when content is materially revised.

Review cycle

Calculator summaries are reviewed when published, after material guideline or source updates, and at least annually for priority calculators.
