Summary
The Perinatal Emergency Team Response Assessment (PETRA) scale is a valid and reliable tool for evaluating teamwork during simulated obstetric emergencies. It effectively assesses multidisciplinary team performance in crisis management.
Area of Science:
- Medical Simulation
- Healthcare Team Performance
- Obstetric Emergency Management
Background:
- Effective teamwork is crucial for managing obstetric emergencies.
- Existing assessment tools may not adequately capture interdisciplinary team dynamics in high-stakes scenarios.
Purpose of the Study:
- To establish the validity and reliability of the Perinatal Emergency Team Response Assessment (PETRA) scale.
- To assess interdisciplinary team dynamics during simulated obstetric crises using PETRA.
Main Methods:
- Observational cohort study utilizing high-fidelity simulations of preeclampsia and postpartum hemorrhage (PPH).
- Multidisciplinary obstetric teams participated in 50 simulations.
- The PETRA scale was used by raters to assess video recordings; construct validity was confirmed by comparing PETRA scores with overall performance ratings.
Main Results:
- High internal consistency (Cronbach's alpha = 0.984) and moderate inter-rater agreement (ICC = 0.49) were found for the PETRA scale.
- Significantly higher PETRA scores were observed in 'good' versus 'poor' performing teams, indicating strong construct validity.
- Generalizability coefficients were 0.83 for PPH and 0.76 for preeclampsia, demonstrating reliable assessment.
Conclusions:
- The Perinatal Emergency Team Response Assessment (PETRA) scale is a valid and reliable instrument.
- PETRA can serve as a valuable tool for assessing and training multidisciplinary teams in managing obstetric crises.
