Analysis of single-donor plateletpheresis procedure parameters and its association with yield in a blood center of Eastern India

BACKGROUND: Single-donor platelets are most commonly used to prevent and treat bleeding in thrombocytopenic patients. Plateletpheresis machines should take less procedure time, optimal yield, and donor comfort. This study aimed to compare different donor parameters such as predonation platelet count and hematocrit (Hct), blood volume (BV) processed, and blood group association with yield. MATERIALS AND METHODS: A retrospective study was conducted in the transfusion medicine department and blood center for 12 months. One hundred and fifty-nine plateletpheresis procedural data on Trima Accel were collected from the register and compiled in the Excel sheet. Donor procedure variables were calculated as mean ± standard deviation. Correlation between donor parameters with yield and anticoagulant (AC) infused to the donor with run time was analyzed using Pearson correlation coefficient in Excel sheet with Microsoft Windows 7 software. The association between blood group and yield was analyzed in GraphPad 9 software, CA. P < 0.05, <0.001 was statistically significant. RESULTS: Predonation platelet count (r = 0.61, P < 0.001) and BV processed (r = 0.18, P < 0.05) were positively correlated with yield. Predonation hemoglobin, Hct, and Run time was positively correlated with AC infused to the donor (r = 0.72, P < 0.001). Different blood groups had no statistical significance association with yield. CONCLUSION: In our study, predonation platelet count directly relates to yield; hence, donors with high platelet count may be considered for better yield. Run time also had a direct relation with AC going to the donor; minimal run time also had a role in preventing adverse effects on the donor.
