The event involved an intern iii system schenkel rechts.The customer reported that on an unspecified date between (b)(6) 2023 and the beginning of (b)(6) 2024, the red infusion systems were leaking again and again during infusion.It was independent of the batch and also of the run rate.The customer works with immunocompromised patients on the kiis3.The leaking infusion systems mean more frequent system changes, which always poses a risk of infection.The customer added that the event occurred again and again since the last report last year.When asked what was the status of the product when the problem occurred, it was answered as "externally undamaged, new packaging." there was no holes, cut, tears and defects noted.The medication involved is 0.45% nacl0.9%+2.5% glucose from serag wiessner.When asked if the chemo did come into contact with the patient or healthcare provider, it was answered as "it is not possible to say exactly, as the defect is located above the filter, but if there is a backflow upwards via the filter, this may be possible.The defect is located above the filter.We administer the chemotherapies below the filter at the y-pieces." there was a potential infection at the catheter.If asked if there was unprotected chemo exposure, it was answered "not visible, may be possible." the chemo spill was not cleaned as per facility protocol and no spill kit was used.The incident occurred while patient use and sometimes the patient reported that the infusion system was wet and dripping.The product problem could possibly contribute to catheter infections.There was also a medical intervention required: therapy for catheter sepsis.There are no relevant tests or lab data available, because the observation that systems repeatedly leak raises the suspicion as to whether external contamination also occurs and promotes a catheter infection.As a relevant medical history the customer mentioned the fact that all patients are immunosuppressed due to chemotherapy for tumor diseases and the patient received medical treatment.There was patient involvement but no patient harm.
