MAUDE Adverse Event Report: TERUMO BCT TRIMA ACCEL; TRIMA ACCEL LRS PLATELET AUTO PAS PLASMA RBC SET

Model Number	80410
Medical Device Problem Code	Adverse Event Without Identified Device or Use Problem (2993)
Health Effect - Clinical Code	No Patient Involvement (2645)
Date of Event	11/29/2019
Type of Reportable Event	Malfunction
Additional Manufacturer Narrative
Investigation: the run data file (rdf) was analyzed for this event.Run data file analysis did not show a conclusive root cause for the higher than expected wbc content in the platelet product reported for this procedure.Alerts that could contribute to wbc contamination of the platelet product, such as ¿centrifuge pressure high¿ or ¿rbc spillover¿, were not generated in this run data file.As the rbc detector cannot count the cells passing by, in order to generate a ¿potential wbc contamination detected¿ message, the rbc detector must see a significant change in the reflectance values.In this procedure, rbc detector reflectance signals did not indicate that wbcs were escaping the lrs chamber.Therefore, the run data file reported that the platelet product could be labeled as leukoreduced.It is also possible, though not conclusive, that this leukoreduction failure may be donor related.Investigation is in process.A follow-up report will be provided.
Event or Problem Description
The customer would like the run data file investigated to determine a possible cause for the elevated white blood cell (wbc) content in the platelet product.There was not a transfusion recipient or patient involved at the time of the residual white blood cell (rwbc) testing, therefore no patient information is reasonably known at the time of the event.The platelet collection set is not available for return because it was discarded by the customer.
Additional Manufacturer Narrative
This report is being filed to provide additional information in b.6, h.6 and h.10.Investigation: the device history record (dhr) was reviewed for this lot.There were no issues noted in the dhr that would have contributed to the elevated wbc count.Root cause: run data file analysis did not show a conclusive root cause for the higher than expected wbc content in the platelet product reported for this procedure.Alerts that could contribute to wbc contamination of the platelet product, such as ¿centrifuge pressure high¿ or ¿rbc spillover¿, were not generated in this run data file.As the rbc detector cannot count the cells passing by, in order to generate a ¿potential wbc contamination detected¿ message, the rbc detector must see a significant change in the reflectance values.In this procedure, rbc detector reflectance signals did not indicate that wbcs were escaping the lrs chamber.Therefore, the run data file reported that the platelet product could be labeled as leukoreduced.It is also possible, though not conclusive, that this leukoreduction failure may be donor related.
Additional Manufacturer Narrative
This report is being filed to provide additional information in h6.Corrective action: an internal capa has been opened to evaluate white blood cell (wbc) contamination in relation to a recent increase in the number of reported wbc contaminations.Investigation is in process.A follow up report will be provided.
