Abstract

Purpose of the study

Tools created to measure procedural competency must be tested in their intended environment against an established standard in order to be validated. We previously created a checklist for ultrasound-guided internal jugular central venous catheter (US IJ CVC) insertion using the modified Delphi method. We sought to further validate the checklist tool for use in an educational environment.

Study design

This is a cohort study involving 15 emergency medicine interns being evaluated on their skill in US IJ CVC placement. We compared the checklist tool with a modified version of a clinically validated global rating scale (GRS) for procedural performance.

Results

The correlation between the GRS tool and the checklist tool was excellent, with a correlation coefficient (Pearson's r) of 0.90 (p<0.0001).

Conclusions

This checklist represents a useful tool for measuring procedural competency.
