Beginning in July, 2001, after learning of the potential hazards to neonatal patients from DEHP exposure, Kaiser Permanente staff underwent a process to identify DEHP-containing medical devices used in the Neonatal Intensive Care Units and to evaluate alternatives. Upon completion of that process, the health system chose to switch to non-DEHP products for three commonly used NICU devices: umbilical vessel catheters, PICC lines, and enteral feeding products.
