Day case surgery, also known as ambulatory surgery, involves planned admission and discharge of a patient within 12 hours for a surgical procedure. It provides several benefits over traditional inpatient surgery such as shorter hospital stays, lower infection rates, and more efficient use of healthcare resources. Common procedures performed as day cases include hernia repairs, cataract removal, and tonsillectomies. Careful patient selection and optimization, as well as coordinated perioperative management involving preoperative assessment and education, regional anesthesia when possible, early mobilization and feeding, and established discharge criteria are important for success. Day case surgery allows for treatment of more patients while maintaining high quality care.
