Brief Summary

Shoulder dystocia is an unpredictable, time-critical obstetric emergency requiring immediate recognition and rapid execution of established maneuvers. To date, there is no published evidence evaluating remote real-time support for the management of shoulder dystocia, which could be especially relevant for providers not frequently confronted with obstetric emergencies. This prospective, randomized, controlled, simulation-based trial compares healthcare providers' performance in managing a standardized shoulder dystocia scenario when supported by remote tele-assistance versus a standard cognitive aid. Teams of at least two healthcare providers manage a standardized scenario on the Laerdal MamaBirthie Task Trainer, with a trained study team member playing the laboring patient. Successful delivery requires completion of three predefined external maneuvers and one internal maneuver. Teams are randomized to Group A (cognitive aid: a standardized visual reference tool with written instructions and pictograms) or Group B (remote tele-support: live video guidance from a credentialed obstetric expert via Signal). The primary outcome is the total performance score (0-25 points). Secondary outcomes include cognitive load (NASA-TLX), usability (System Usability Scale), and subjective experience and communication quality (5-point Likert scales).

Outcome Measures

Primary Outcomes (1)

  • Total performance score

    Total performance score for the management of the standardized shoulder dystocia scenario (range 0-25 points; higher scores indicate better performance).

Secondary Outcomes (4)

  • Cognitive load (NASA-TLX)

    Immediately after the simulated scenario

  • Usability (System Usability Scale, SUS)

    Immediately after the simulated scenario

  • Subjective experience (Likert)

Study Arms (2)

Group A: Cognitive Aid

ACTIVE COMPARATOR

Teams manage the standardized shoulder dystocia scenario supported by a standardized visual cognitive aid (written instructions and pictograms of the required external and internal maneuvers). No additional clinical assistance is provided after scenario initiation.

Other: Cognitive Aid

Group B: Remote Tele-Support

EXPERIMENTAL

Teams manage the standardized shoulder dystocia scenario supported by live real-time video guidance from a credentialed obstetric expert via a study-issued mobile device using Signal.

Other: Remote Tele-Support

Interventions

Live real-time video guidance provided by a credentialed obstetric expert (midwife or obstetrician) via a study-issued mobile device using Signal (GDPR-compliant secure video call) throughout the standardized shoulder dystocia scenario.

Group B: Remote Tele-Support

A standardized visual reference tool provided at the start of the scenario, containing concise written instructions and pictograms illustrating the three required external maneuvers and the single internal maneuver. No additional clinical assistance is provided after scenario initiation.

Group A: Cognitive Aid
