Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint is usability, measured using a standardized questionnaire based on the System Usability Scale (SUS). The quantitative analysis focuses in particular on the dimensions of usability, ergonomics, and the comprehensibility of the imaging. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoints relate to the clinical application of ultrasound-guided vascular cannulation under VR conditions and include: Duration of the procedure (defined as the duration of the sterile phase) Duration of the puncture (defined as the time from the first puncture attempt to successful catheter insertion) Number of puncture attempts (including failed punctures) Number of guidewire placements (as a measure of technical feasibility) Complications, in particular: Hematoma formation (assessment on the following day, taking anticoagulation into account) Catheter-associated infections Termination of the puncture for other reasons Suspected nerve injury (sensory deficits on the following day) | — |
