Prevalence and predictors of adverse reactions in plateletpheresis donors with the perspective of donor safety in a tertiary care hospital of Northern India

Background: Plateletpheresis procedures are generally safe and associated with low adverse reactions. Although donor reactions and injuries are self-limited events, they may discourage donors from future platelet donations. Aim: The purpose of this study was to determine the prevalence and predictors of adverse donor reactions in plateletpheresis donors, which could serve as targets for interventions to reduce reactions. Materials and Methods: The study included 106 platelet donors over a period of 2 years. The demographic, biometric, and clinical parameters were noted. The data were analyzed for predictors of adverse donor reactions. Statistical Analysis Used: The data were analyzed using independent sample t-test to correlate donor variables such as gender. To correlate other variables such as age, weight, and whole blood processed, Chi-square test was used. Results: A total of 106 plateletpheresis donations were performed and 13.2% of vasovagal reactions were observed. The significant predictive factors for reactions were young female donors with low body weight in which more than 2.5 L volume of whole blood was processed and more than 250 ml of acid, citrate, and dextrose-A was infused and with single venous access procedures. Conclusions: The results of this study are encouraging and helpful in identifying donors at risk for developing adverse reactions during plateletpheresis so that proper and close observation during and after donation as well as timely intervention can prevent most of the unpleasant events of plateletpheresis donors.
