Central Venous Catheter Insertion: A Scoring System for Evaluation of Both the Procedure and the Operator (CVCI Score/Gaber Score).

introductionCurrently, there is no method to assess the performance while inserting a central venous catheter. We suggest a new scoring system for evaluation of both the technique as well as the operator, and then we applied it for the comparison between the landmark and ultrasound techniques to assess its validity

resultsIn group (A), 20% of patients in the landmark group achieved score 4, while 82% of patients in the ultrasound group achieved the same score. This suggests that the ultrasound technique for catheterization of IJV decreased overall complications and improved the success rate. In group (B), there were 70% of patients in the landmark group who achieved score 5, while 49% of patients in the ultrasound group achieved the same score which proposes that the landmark technique might be deceptively better than the ultrasound technique for catheterization of SV. This could be because the time required for catheterization of SV by the ultrasound technique was longer than that in the landmark technique. Overall complications of 15% with the landmark technique vs. 2% with ultrasound guidance in this group of patients are not only statistically significant but also increase morbidity and mortality with a highly invasive procedure. Complications and their incidences are by far more significant than seconds of time. Our results suggest that the ultrasound technique could decrease the incidence of overall complications, but it is time-consuming in group (B). These results support the validity of our new scoring system.

conclusionWe suggest a new scoring system for CVC insertion that can be used for evaluation of both the technique and the operator. It can evaluate the performance of junior staff and follow their progress. It can be applied in the medical and critical care practice as well as the quality management privileges and protocols.
