Good morning. Does the ISPD have a position on use of Effluent Sample Bags specifically developed and designed to collect specimens from the patient transfer set for culture when peritonitis is suspected? The sample bag that I have seen is made by a well known vendor of CAPD solutions and supplies (dual bag, y-connection), and the procedure for collection of the specimen mirrors that used for connection and disconnection during an exchange. The product is essentially a miniature drain bag. There is no instillation of solution involved.

Thank you for your question. The ISPD does not have a position statement on the practice of using the Effluent Sample Bags you mention to collect a specimen of PD fluid from a patient with suspected peritonitis. I understand some PD units in the United States do use these Effluent Sample Bags to collect the PD fluid, reasoning that, while there is an added cost, the benefit is that these small bags do have an injection port. Thus, a nurse, using aseptic technique, can use the injection port of the small collection bag to aspirate a sample of the PD fluid and then transfer this aspirated PD fluid to a sterile collection container, for example, blood culture bottles. The risk of contamination of the PD fluid at this time is therefore minimized. Not all single drainage bags for PD fluid have an injection port.
