Clinical inputs

DIPSS risk category

Enter the already determined DIPSS risk category. DIPSS Plus transforms low, intermediate-1, intermediate-2, and high DIPSS categories to 0, 1, 2, and 3 points; it does not rescore the five raw DIPSS variables.

Unfavorable karyotype: complex or one or two abnormalities including +8, −7/7q−, i(17q), inv(3), −5/5q−, 12p−, or 11q23 rearrangement

Platelet count <100 ×10⁹/L

Red-cell transfusion need
