Faster Cheaper Safer: A Randomised Trial on the Use of Intracavitary ECG for Central Venous Access
Introduction: Traditionally, confirmation of a central venous access device (CVAD) placed at the bedside is the chest x ray (CXR). If incorrect position by CXR after insertion, the device is required to be repositioned or reinserted. Intra-cavitary electrocardiography (IC-ECG) guided CVAD placement has been proposed as a more accurate alternative to traditional CVAD insertion. Most studies to date have tested the effectiveness of IC-ECG exclusively on central venous catheters or peripherally inserted central catheters and in specific patient cohorts. This study compared the clinical and cost benefit of IC-ECG in a broad patient population with a range of CVADs.
Method: Pragmatic, randomised control trial comparing the accuracy and cost between traditional CVAD and IC-ECG guided insertion. Eligible patients were randomly assigned to have catheter placed by traditional technique or IC-ECG in a 1:1 ratio (172 patients in each group). The primary outcome measure was the rate of catheters between the two groups observed to be malpositioned after initial insertion.
Results: In the IC-ECG group, 170 catheters (99%) were placed accurately and did not require repositioning compared to 139 catheters (81%) in the traditional group (p<.001). Median procedural time was 12 minutes (IQR 10 – 17 minutes) in IC-ECG group verses 30 minutes (IQR 24 – 43 minutes) in control group (p<.001). Average cost saving per patient was $64 Australian (or $96,000 annually for our service). When IC ECG was used for bedside chronic catheter placement (implanted ports, tunnelled dialysis catheters) the cost savings were up to $599 per patient.
Discussion and Conclusion: IC-ECG has shown to be safe, accurate, with significant cost, organisational and patient benefits that include reduced radiation exposure, reduced sterile dressing interruptions and catheter manipulations.
