Clinical factors influencing corrected count increment.

Refractoriness to platelet transfusions is a common clinical problem. The present study was conducted to look into patient characteristics affecting the corrected count increment in a tertiary care referral hospital. A total of 161 aphaeresis platelet units were transfused to 40 patients with varied clinical diagnoses. The mean platelet increment was 17,789/mm(3). Median corrected count increment was 7344 and percentage platelet recovery was 22.82%. Logistic regression analysis revealed significant influence of splenomegaly and anti-platelet drugs on refractoriness. Fever, bleeding, sepsis, disseminated intravascular coagulation and cyclosporine use, though more common in the patients with refractoriness they were not statistically significant.
