Background: Although home parenteral nutrition (HPN) is often indicated in cancer patients, many physicians are concerned about the risks potentially associated with the use of central venous access devices (VADs) in these patients. The aim of this prospective study was to investigate the actual incidence of VAD‐related complications in cancer patients on HPN. Methods: All adult cancer patient candidates for VAD insertion and HPN were enrolled. The incidence of complications associated with 4 types of VADs (peripherally inserted central catheter [PICC], Hohn catheter, tunneled Groshong catheter, and port) was investigated, as well as the most significant risk factors. Results: Two hundred eighty‐nine VADs in 254 patients were studied, for a total of 51,308 catheter‐days. The incidence of catheter‐related bloodstream infections (CRBSIs) was low (0.35/1000 catheter‐days), particularly for PICCs (0/1000; P < .01 …
