The VExUS-Users study is an international collaborative project to which all physicians using the Venous Excess Ultrasound (VExUS) assesment in their clinical practice can participate to further our understanding.

The aim of the project is to determine how information from venous Doppler during Point-Of-Care Ultrasound (POCUS) impacts clinical decision-making at the bedside.

---

The secondary objectives will be to document how frequently VExUS users employ
the modality, which components of the VExUS examination are most used, the
effect on self-reported diagnostic uncertainty, and the most common therapeutic
changes performed in response to information from the VExUS assessment.

What is asked of participants: Clinicians who agree to participate in the study are asked, as much as possible, to record information about all VExUS assessments they perform in their day-to-day clinical practice in a smartphone application during a period of 4 months (from the day of enrollment in the study up to 4 months afterward).

What is NOT required from participants:

• No personal information from patients are collected.
• No dedicated research staff is needed.
• Ultrasound images are not recorded or shared

What are the requirements to participate?

• Being a clinician defined as a physician holding a MD or DO involved in direct patient care. These include physicians from all specialties and general practitioners.
• Use of VExUS assessment at least once per month during the past 4 months.
• Must succeed an online test to show appropriate knowledge about the VExUS score (<5 minutes duration).
• Have access to an ultrasound machine suited to perform the some components of the VExUS assessment during their clinical practice.
• Have more than 30% of their time dedicated to clinical work during the following 4 months
