Bank to bedside: A reliable and efficient transportation of blood by pneumatic tube system

Abstract

Background: Turnaround time (TAT) is an important quality indicator in blood banking. This study evaluated the effectiveness of the pneumatic tube system (PTS) to reduce TAT and its effect on the quality of the blood products. Materials and Methods: The PTS (Swisslog GMBH, Germany) which connects to 29 stations was installed at our 2032-bedded tertiary care referral center. The system transports the carrier at an average speed of 25 feet/s (7.6 m/s). Acknowledgment slips were sent along with the blood components through this carrier system to know the time of receipt. Quality control parameters were checked before and after PTS transport in 10 bags of each of the blood components (packed red blood cells [PRBC], platelet concentrate, and fresh frozen plasma [FFP]). Data were analyzed using IBM SPSS Statistics 20. Results: PTS was used for 220 events to deliver 69% PRBC (n = 152), 15% FFP (n = 34), 14% platelets (n = 30), and 2% cryoprecipitate (n = 4), respectively, to 11 destinations. The average transport time by PTS was 1.36 ± 0.34 min and for human-based transport, it was 7.92 ± 1.40 min and this difference was found to be statistically significant (P < 0.001). The mean latent time was 5.85 ± 4.39 min. Conveyance in the PTS did not reinforce any negative changes on the quality of any blood component. Conclusion: PTS is rapid and reliable for the transport of the blood products to bedside.
