Derivation of a Performance Checklist for Ultrasound-Guided Arthrocentesis Using the Modified Delphi Method

SONOSIM SUMMARY:  Through collaboration of several physicians, using a modified Delphi Method, this research was able to create a structured guideline for completing an ultrasound-guided arthrocentesis. The researchers hope that this checklist provides standardization so that needle-insertion accuracy can improve, which in turn will help with the integration of ultrasound guidance into clinical practice. After reaching a final consensus among physicians, the research team suggests further research in the evaluation of checklist effectiveness in a clinical setting.

Abstract

Objectives
Arthrocentesis is an important skill for physicians in multiple specialties. Recent studies indicate a superior safety and performance profile for this procedure using ultrasound guidance for needle placement, and improving quality of care requires a valid measurement of competency using this modality.

Methods
We endeavored to create a validated tool to assess the performance of this procedure using the modified Delphi technique and experts in multiple disciplines across the United States.

Results
We derived a 22-item checklist designed to assess competency for the
completion of ultrasound-guided arthrocentesis, which demonstrated a Cronbach’s alpha of 0.89, indicating an excellent degree of internal consistency.

Conclusions
Although we were able to demonstrate content validity for this tool,
further validity evidence should be acquired after the tool is used and studied in clinical and simulated contexts.
