Simulating continuous renal replacement therapy: usefulness of a new simulator device

Area of Science:

• Medical Simulation
• Nephrology
• Medical Device Development

Background:

• Training in life-support procedures traditionally carries inherent patient risk.
• Continuous renal replacement therapy (CRRT) requires specialized management skills.
• Realistic simulation of CRRT scenarios is challenging but crucial for effective training.

Purpose of the Study:

• To analyze the performance and utility of a novel device for externally controlling CRRT machines.
• To create realistic clinical conditions and complications for simulated patients during CRRT training.
• To assess the effectiveness of the device in enhancing healthcare professional education.

Main Methods:

• A simple, custom-made mechanical device was designed to control monitorable pressures on CRRT machines.
• In vitro testing was followed by 16 high-fidelity patient-simulation scenarios in pediatric CRRT courses.
• Performance was evaluated through real-time monitoring and anonymous surveys assessing student and teacher satisfaction.

Main Results:

• The device accurately simulated common CRRT complications, including catheter issues and filter coagulation.
• Instructors found the device user-friendly and realistic.
• Trainees perceived the simulated clinical conditions as highly realistic, unaware of the simulator's presence.

Conclusions:

• The developed mechanical device is highly effective for simulating CRRT scenarios and complications.
• This tool offers a valuable, risk-free method for training healthcare professionals in CRRT management.
• The device enhances the realism and effectiveness of medical simulation for critical care procedures.
