Event or Problem Description
The peritoneal dialysis (pd) patient contact reported to fresenius medical care (fme) customer service that the pd patient has peritonitis.Attempts to obtain additional information were unsuccessful.
Additional Manufacturer Narrative
Clinical review: there is a temporal relationship between peritoneal dialysis utilizing the liberty cycler set and the patient event of peritonitis.However, there is no documentation in the complaint file to show a causal relationship between the adverse event, and the use of the liberty cycler set.Additionally, there is no allegation or evidence of a device malfunction or deficiency, or cycler set defect reported for this event.Although no information was provided related to culture results or the determined cause of the reported peritonitis, all pd patients are at risk of peritonitis due to a compromised immune system and the increase of potential for microbial contamination from dialysis techniques.Most cases of peritonitis are caused by touch contamination by the patient with the pd catheter being a source of entry for organisms into the peritoneum.Based on limited information and no allegation of a malfunction, deficiency, or defect, the liberty cycler set can be excluded as the cause of the patient¿s reported peritonitis event.The plant investigation is in process.A supplemental mdr will be submitted upon completion of this activity. .
