Abstract

Abstract: Objectives: To compare the performance of the corrected count increment (CCI) and three other formulas to assess 24-hour posttransfusion platelet survival in hematology patients. Methods: Twenty-four-hour posttransfusion platelet counts were analyzed after apheresis platelet transfusion. Platelet increment (PI), percent platelet recovery (PPR), and percentage platelet increment (PPI) were compared with CCI by receiver operating characteristic analysis. Clinical factors that influence platelet survival were assessed by logistic regression. Results: In total, 142 apheresis platelet transfusions in 85 hematology patients were studied. Mean (SD) CCI at 24 hours was 11, 869 (10, 125). Compared with CCI, the sensitivity of other formulas ranged from 89.4% to 95.7% and specificity from 94.7% to 100%. Cutoff values were 15.7 × 10 3 /µL for PI, 11.4% for PPR, and 17% for PPI. For ABO-compatible vs incompatible transfusions, CCI was 14, 070/µL vs 9, 176/µL ( P = .007). Negative factors for all formulas were sepsis, hypotension, and amphotericin B. Conclusions: PI, PPR, and PPI are comparable to CCI for assessing 24-hour platelet survival.
