Intracavitary electrocardiography-guided PICC insertion

Abstract:

Background: The placement of peripherally inserted central venous catheters (PICCs) has traditionally relied on measurements and anatomical landmarks. It involves post-placement chest X-rays (CXRs) and occasional repositioning, which incur additional direct and indirect costs, such as delays in care and staff time. The aim of this study was to assess the cost-effectiveness of a routine post-procedural CXR in the era of ultrasound and intracavitary electrocardiography (IC-ECG)-guided PICC insertion.

Methods: A retrospective two-center study was conducted to review the clinical records of all patients who had PICCs in the Venous Access Center of Peking University Cancer Hospital & Institute and The Affiliated Qingdao Central Hospital of Qingdao University between 1 January 2019 and 30 June 2020. PICC placement was only available to patients who were 18 years or older, had in-sinus rhythm. The incidence of catheter misplacement after insertion was measured. Cavoatrial junction or the lower third of the superior vena cava (SVC) were defined as ideal catheter tip locations. A logistic regression analysis was performed to examine potential risk factors associated with PICC-related complications and a cost analysis was conducted to assess the economic impact of the use of CXR.

Results: There were 2,863 samples from 2,653 patients included. The overall incidence of intraprocedural and primary catheter misplacement was 7.3% (n=210) and 0.70% (n=20), respectively. There was a high risk of primary catheter misplacement when the left-arm was chosen for placement . The overall cost of performing CXR for screening of PICC-related complications was $23,858 per year, and that of using CXR to diagnose 1 case of catheter misplacement was $1,789.

Conclusions: This study confirms that misplacement of PICCs guided by ultrasound and IC-ECG is rare and that postprocedural CXR is very costly. In our setting, routine postprocedural CXR is unnecessary especially when the PICC is catheterized in the right arm, and is not a wise option.
