PURPOSE: To analyze the patterns of postplacement tip malposition in peripherally inserted central catheters (PICCs) placed at bedside, and to describe results of bedside and imaging-guided correction of tip malposition. MATERIALS AND METHODS: With use of a quality assurance database, all episodes of tip malposition in PICCs placed at bedside were reviewed. Catheter tip location, success or failure of bedside repositioning (in a subset of patients, by using over-the-wire techniques), findings in the interventional radiology (IR) division, and tip correction method used in the IR suite (repositioning vs replacement) were determined with a review of medical records. RESULTS: During the 18-month study period, 2,367 attempts were made to place a PICC at bedside; 1,654 attempts (70%) were initially successful. Of these, 163 tips (10%) were malpositioned. Complete records for 132 malpositioned tips were available for analysis. Malpositioned tips were located in the ipsilateral internal jugular vein in 45 of the 132 cases (36%), axillary vein in 36 cases (27%), ipsilateral subclavian vein in 25 cases (19%), ipsilateral brachiocephalic vein in 15 cases (11%), contralateral subclavian vein in four cases (3%), contralateral brachiocephalic vein in two cases (2%), contralateral internal jugular vein in one case (1%), and subclavian tributary in one case (1%). In three cases (2%), the tip was coiled in the superior vena cava. Malposition was corrected with catheter exchange in 76 of the 132 cases (58%), repositioning in 48 cases (36%), or removal in one case (1%). Spontaneous correction occurred in seven of the 132 malpositioned tips (5%). One hundred nine tips (83%) were repositioned in the IR division with use of imaging guidance, with 100% success. Twenty-five attempts were made to correct malposition at bedside; 16 of those attempts (64%) were successful. CONCLUSION: Tip malposition is relatively frequent with bedside placement of PICCs. Preliminary data suggest that most malpositions can be corrected with bedside techniques. Spontaneous correction may occur but is relatively uncommon.
