About this trial
This feasibility study will evaluate the accuracy of telementored eFAST (Extended Focused Assessment with Sonography in Trauma) in detecting abdominal free fluid in patients who have recently undergone liver surgery. The primary goal is to determine how well the remote-guided ultrasound can identify fluid accumulation compared to conventional ultrasound performed by a radiologist. Participants in this study will be examined with ultrasound, supported in real-time by a remote expert, to assess its accuracy and other relevant performance metrics.

Diagnostic testUltrasound examination guided in real-time by a remote expert for detecting free fluid.
Treatment groups
Trial outcomes
Primary outcomes
Concordance rate
Comparison of telementored eFAST vs. CT and expert examination with percentage agreement, Cohen's cappa and Gwet's AC1
Exam duration
Time measurement from probe contact to mutual agreement between expert and examiner that exam is finished in minutes:seconds
Image quality
The radiologist providing remote guidance will assess the image quality using a 1-5 Likert scale based on a feedback questionnaire adapted from Mazur et al
Secondary outcomes
Mental effort
Cognitive workload during eFAST, measured by NASA Task Load Index on a numerical score (1-9)
User experience
Feedback questionnaire adapted from McBeth et al.
Learning curve (Mental effort)
Asess improvement in eFAST exam efficiency by comparing mental effort over multiple examinations
Learning curve (efficiency)
Evaluate whether telementored examiners show changes in eFAST examination duration over time. The duration of each examination will be compared to previous ones for the same examiner to identify trends in efficiency across multiple sessions.
