Healthcare simulation is a teaching and training methodology that uses immersive and interactive environments to simulate real-life medical scenarios. This method allows healthcare professionals, students, and other individuals to practice and improve their clinical skills, decision-making abilities, and communication techniques in a risk-free environment. Healthcare simulation can take many forms, such as high-fidelity mannequins, virtual reality simulations, standardized patients, and computer-based simulations. It is used in a variety of healthcare settings, including hospitals, medical schools, nursing programs, and emergency response training centers. The goal of healthcare simulation is to enhance patient safety, improve clinical outcomes, and increase the competence and confidence of healthcare providers. Research in this area focuses on evaluating the effectiveness of simulation-based training programs, developing new simulation technologies, and exploring innovative ways to integrate simulation into healthcare education and practice.
