Outcomes of tunnelled cuffed centrally inserted central catheter removal: A retrospective cohort study

Background

Most children with cancer will require a central venous access device (CVAD) to administer cancer treatment. A commonly used CVAD is a tunnelled cuffed centrally inserted central catheter (TC-CICC). There is little information available to guide best practice when removing this type of CVAD. At our institution, TC-CICCs are removed by using either the traction or dissection methods. This study will describe the outcomes associated with each technique.

Methods/results

A retrospective cohort study was undertaken at a quaternary children's hospital in Melbourne, Australia. Data related to characteristics of TC-CICC removal success, post-removal complications and an economic evaluation were carried out. There were 149 patients who underwent traction removal and 100 who had their TC-CICC removed using the dissection technique. In the traction group, 136/149 (91%) patients had their device successfully removed on the first attempt, whereas 99/100 (99%) were removed on the first attempt with dissection. Of the 136 successful traction removals, cuff status was documented in 72 cases. The cuff remained in situ in 46/72 (64%) cases, and six of 72 (8%) patients experienced a complication. There were no documented cases of cuff retention in the dissection group. In the 2019–2020 financial year, the estimated average cost of traction removal was A$387, whereas the estimated average cost of day case surgery was A$2560.

Conclusion

This study has highlighted that the traction technique is a safe, efficient and cost-effective approach to TC-CICC removal. Further research is required to understand the patient and family experience of TC-CICC removal.
