Comparison of Peripherally Inserted Central Catheters and Totally Implanted Venous Access Devices As Chemotherapy Delivery Routes in Oncology Patients: A Retrospective Cohort Study

This study aimed to evaluate peripherally inserted central catheters (PICCs) and totally implanted venous access devices (TIVADs) as chemotherapy delivery routes. From May 2016 to April 2019, patients with malignancies who had PICCs or TIVADs inserted for chemotherapy were enrolled. We reviewed the patients' medical records for information concerning demographics, comorbidities, catheter-related complications, and catheter -service days. All patients included in both groups were also assessed for complication-free catheter survival and completion rates of chemotherapy. A total of 467 catheter insertions (185 PICCs and 282 TIVADs) were included in this study. The PICCs were associated with a higher rate of complication-related catheter removal than TIVADs (hazard ratio, 6.5954; 95% confidence interval, 2.394-18.168; <0.001). The completion of chemotherapy was observed in 77 (41.6%) patients with PICCs and 128 (45.4%) with TIVADs ( = 0.442). The mean duration of catheter service-days was shorter for the patients in the PICC group who completed chemotherapy than those in the TIVAD group (101.3 ± 93.2 vs 245.3 ± 115.9, respectively,  < 0.001). Although PICC was an independent risk factor for complication-related catheter removal, there was no difference in the chemotherapy completion rate between the groups. Therefore, PICCs need to be considered preferentially in patients who require a chemotherapy delivery route for short-term chemotherapy.
