A&E, short for "Accident and Emergency," is a medical department in hospitals that provides immediate treatment for urgent health issues. It is designed to handle life-threatening conditions, serious injuries, and sudden illnesses. Patients typically visit A&E when they require quick medical attention that cannot wait for a regular doctor's appointment. In many countries, A&E departments are open 24/7 and are staffed by a team of healthcare professionals, including doctors, nurses, and paramedics. They assess patients' conditions, perform necessary tests, and provide treatments. A&E is often the first point of contact for emergencies, making it a critical component of the healthcare system.
