An observational study in Ultrasound-guided Fluid Management, Volume Responsiveness and Venous Congestion Assessment, sponsored by University Hospital, Basel, Switzerland. Recruiting at 1 site in Switzerland. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-26.
Sponsored by University Hospital, Basel, Switzerland · Observational
The aim of this study is to assess the knowledge, attitudes, and practices of ICU physicians in Switzerland regarding the use of ultrasound for fluid management and evaluation of venous congestion.
This multicenter survey study aims to explore the experiences, perceptions, and attitudes of intensive care unit (ICU) physicians in Switzerland regarding the use of ultrasound for fluid management. The primary objective is to assess participants' knowledge of ultrasound techniques to predict fluid responsiveness and evaluate venous congestion. The study will also compare familiarity with traditional methods (e.g., central venous pressure, IVC-Inferior Vena Cava ultrasound) and newer approaches such as the VEXUS (Venous Excess Ultrasound Score) score or assessment of stroke volume changes during passive leg raise or mini fluid challenges.
Participants will complete an online questionnaire via REDCap, covering demographics, professional background, ultrasound training, knowledge and experience with ultrasound for volume management and venous congestion, as well as institutional factors and suggestions for improvement. The survey will be distributed to physicians working in ICUs at multiple Swiss hospitals, including the University Hospital Basel, Kantonsspital Aarau, Inselspital Bern, Spitalzentrum Biel, and Triemlispital Zürich. Participation is voluntary, and informed consent will be obtained electronically at the start of the questionnaire.

Physician Knowledge and Experience Using Ultrasound for Fluid Management and Venous Congestion
The primary outcome is the proportion of ICU physicians in Switzerland who demonstrate knowledge and report regular use of ultrasound techniques for assessing fluid responsiveness and venous congestion, including traditional methods and newer approaches. Data will be collected through a structured online questionnaire.
