    Advice

    The Revised Natural History Model for PSC is a convenient and simple scoring system.

    Formula

    Risk Score = 0.03*(age [y]) + 0.54*loge(bilirubin [mg/dL]) + 0.54*loge(aspartate aminotransferase [U/L]) + 1.24*(variceal bleeding [Y=1,N=0]) - 0.84*(albumin [g/dL])

    Facts & Figures

    • Scores ≤0 - low risk group.
    • Scores 0-2 - intermediate risk group.
    • Scores >2 - high risk group.
