Reliability and reproducibility of the venous excess ultrasound (VExUS) score, a multi-site prospective study: validating a novel ultrasound technique for comprehensive assessment of venous congestion
Study context
- Population
- Patients with VExUS exams interpreted by four attending physicians of diverse specialties
- Participants
- 84 paired exams
- Exposure
- VExUS interpretation with vs without concurrent ECG
- With ECGn = 60
- Outcome
- Inter-rater reliability (IRR) and inter-user reproducibility (IUR) of VExUS interpretation (Kappa statistic, ICC)
