For those that have CXR taken for patients arriving with a PICC already in place, how do you manage the serial patients? A previous list serv showed that they are considered in use and a CXR will not be taken. The question has now come up, is there a time frame of when the PICC was last accessed? What exactly defines a serial patient? Your assistance is greatly appreciated. Thank you. Yvonne Cales, SMH.
