Brief Summary

The goal of this study is to evaluate whether remote asynchronous feedback is non-inferior to direct synchronous feedback during simulation-based training for ultrasound-guided popliteal sciatic nerve block performance. The main questions it aims to answer are: Does asynchronous feedback achieve technical skill acquisition outcomes comparable to direct synchronous feedback? Can asynchronous feedback optimize teaching resources without compromising training quality? Researchers will compare two feedback modalities within a simulation-based training program for deliberate practice of ultrasound-guided popliteal sciatic nerve block techniques. Participants will: Receive training with either direct synchronous feedback or remote asynchronous feedback Perform simulation-based deliberate practice sessions Be assessed using validated instruments for technical skill performance

Outcome Measures

Primary Outcomes (1)

• Performance assessment

  The PRE and POST assessments were videotaped for evaluation by 2 independent and blinded reviewers. The simulation center staff recorded the assessment videos for a standard vision of the participant's hands and the ultrasound image. Two reviewers rated each resident's performance using an specific GRS previously validated. The reviewers were different from the instructors.

  8 weeks

Secondary Outcomes (1)

• ICSAD measurement

Study Arms (2)

Synchronous direct feedback (SYNC)

ACTIVE COMPARATOR

The control group practiced with synchronous direct feedback (SYNC). The SYNC group attended the simulation laboratory for practice sessions. Residents were scheduled to practice with the instructor in a one-to-one ses- sion. The instructor was present during all the sessions and gave instructions and feedback in real time throughout all sessions (traditional face-to-face feedback modality).

Other: Synchronous direct feedback

Asynchronous distance feedback (ASYNC).

EXPERIMENTAL

The experimental group practiced with asynchronous distance feedback (ASYNC). Residents scheduled their sessions and attended the simulation laboratory alone. The resident logged in to the C1DO1 platform.The student recorded himself, performing the observed technique. The instructor was not present and provided feedback asynchronously via a C1DO1 platform. The ASYNC included texts, audio recordings, drawings annotating the trainee's video, and short example error videos from a library. In addition to the specific feedback in response to residents' videos, instructors also provided an objective assessment based on scores using a 9-item global rating scale (GRS). The student reviewed their feedback in the platform and identified the skills to improve for the next session.

Other: Asynchronous distance feedback

Interventions

Asynchronous distance feedback OTHER

The experimental group practiced with ASYNC. Residents sched- uled their sessions and attended the simulation laboratory alone. The resident logged in to the C1DO1 platform. In the platform, the second 4 stages were practical exercises.
