Incidence of Platelet Refractoriness in Adult Acute Leukemia Patients Receiving Prestorage Filtered Blood and Comparing With Historical Control

This research project is evaluate the incidence of platelet refractoriness in newly diagnosed acute leukemia patients receiving PFB during induction and first consolidation phase chemotherapy compared to 2 historical control groups which are patients receiving non-leukocyte depleted blood product group and leukocyte depleted blood product group and demonstrate cost-effectiveness of using blood products with filtered process to prevent clinical platelet refractoriness compare with using HLA-matched blood products after platelet refractoriness occurs

This study the objective is to study and compare the incidence of Platelet Refractoriness. of the group that received PFB blood compared to the group that received LPPC/LPB blood in the past in patients with AML and ALL at Siriraj Hospital From the literature review, it was found that the incidence of Platelet Refractoriness of the group receiving LPPC/LPB blood in patients with AML and ALL was 46% and the incidence of Platelet Refractoriness Of the group receiving PFB blood in AML and ALL patients, it was 11% .But from the collection of blood bank data Siriraj Hospital during 2020-2021 found that the incidence of Platelet Refractoriness in AML and ALL patients who received PFB blood was approximately 27%. The researchers estimated that In this study There may be an incidence of Platelet Refractoriness. of the group receiving PFB blood in patients with AML and ALL was as high as 27%, and when determining the sample size in the group receiving LPPC/LPB blood, it was 2 times greater than the group receiving PFB blood and setting the standard value according to the table Z equal to 1.96 and The power of the test is 80% when the sample size is calculated with the formula Comparing the proportion values between two independent populations (Testing two independent proportion: Formula (without continuity correlation))
