| Thrombocytopenia Compare the highest platelet count within the sequence of declining platelet counts with the lowest count to determine the % of platelet fall. (Select only 1 option) |
♦ > 50% platelet fall AND nadir of ≥ 20 AND no surgery within preceding 3 days | ♦ > 50% platelet fall BUT surgery within preceding 3 days OR ♦ any combination of platelet fall and nadir that does not fit criteria for score 2 or score 0 (eg. 30-50% platelet fall or nadir 10-19) |
♦ < 30% platelet fall any platelet fall with nadir < 10 |
| Timing (of platelet count fall or thrombosis) Day 0 = first day of most recent heparin exposure (Select only 1 option) |
♦ platelet fall day 5-10 after start of heparin ♦ platelet fall within 1 day of start of heparin AND exposure to heparin within past 5-30 days |
♦ consistent with platelet fall days 5-10 but not clear (eg. missing counts) ♦ platelet fall within 1 day of start of heparin AND exposure to heaprin in past 31-100 days ♦ platelet fall after day 10 |
