Cost analysis and evaluation of covers for a central venous catheter insertion site in BMT

Abstract

A central venous catheter is indispensable to maintain a prolonged venous access, and is widely used in bone marrow transplants. The implementation of a central venous catheter (CVC) is necessary to keep a safer venous access for long periods of time. It is necessary as well to maintain blood aspiration, administration of medication and blood products. However, the choosing of different dressing covers for the catheter insertion site is controversial given the difference in its cost and ability to prevent infect ions. This study aimed to analyze the use and cost of different types of Central Venous Catheter covers, how often it is changed, and the appearance of infections related to that device in a Bone Marrow Transplantation Unit. A retrospective research with an exploratory and descriptive approach was carried out. Data was collected from 68 patients' medical records. It was observed that a transparent film dressing lasted from 4 to 7 d ays, whilst sterile gauze pads were in place from 24 hours to 48 hours. The use of sterile gauze pads had a higher cost when compared to transparent film as the former needed to bechanged more frequently during the week. There was no connect ion between the use of the different dressing covers and the appearance of infection. In conclusion a constant evaluation of the nursing care procedure is needed, along with an appropriate care, research and sensible management. Further studies on the importance of standardized procedures could lead to the improvement of the nursing care service and of the hospital in general.
