A randomized, retrospective chart review was conducted at a medium-sized community hospital to verify appropriateness of peripherally inserted central catheter (PICC) use in 49 inpatient patients. Study results support the Infusion Nurses Society recommendation to use PICCs to facilitate either short- or long-term intravenous therapy of vesicants, irritants, and any medications with a pH less than 5 or greater than 9 and osmolarity greater than 600 mOsm/L. All PICC insertion criteria recommended by the Centers for Disease Control and Prevention were met except one--the intended duration of intravenous therapy of more than 6 days. Identical PICC selection criteria are needed to standardize clinical practice.
