Out-of-hospital care, also known as prehospital care, refers to medical care provided outside of a traditional hospital setting by emergency medical services (EMS) providers. This includes responding to medical emergencies, providing initial treatment and stabilization, and transporting patients to hospitals for further care. Out-of-hospital care plays a crucial role in saving lives and improving patient outcomes in emergency situations. This research area focuses on improving the quality, efficiency, and effectiveness of out-of-hospital care, as well as addressing challenges such as resource allocation, communication, and coordination among various healthcare providers in the prehospital setting. Key topics of study may include patient outcomes, best practices for emergency medical interventions, public health initiatives, and technology advancements in out-of-hospital care.
