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.

Trial outcomes

Primary outcomes

1

Concordance rate

Comparison of telementored eFAST vs. CT and expert examination with percentage agreement, Cohen's cappa and Gwet's AC1

Time frame
Assessed immediately after each ultrasound examination (telementored and conventional) for each participant
2

Exam duration

Time measurement from probe contact to mutual agreement between expert and examiner that exam is finished in minutes:seconds

Time frame
Within 72 hours of surgery for each participant
3

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

Time frame
Assessed retrospectively at the end of data collection, expected to be within 6 months after the final recorded examination

Secondary outcomes

1

Mental effort

Cognitive workload during eFAST, measured by NASA Task Load Index on a numerical score (1-9)

Time frame
Immediately after each telementored eFAST examination
2

User experience

Feedback questionnaire adapted from McBeth et al.

Time frame
Immediately after each telementored eFAST examination
3

Learning curve (Mental effort)

Asess improvement in eFAST exam efficiency by comparing mental effort over multiple examinations

Time frame
Data will be evaluated cumulatively at the end of the study, through study completion, estimated to be up to 6 months after the final participant's examination
4

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.

Time frame
Assessed cumulatively through study completion, estimated up to 6 months after final participant examination
