Admission involves receiving patients into a hospital for observation, investigation, treatment or care. There are two main types of admission - emergency admissions for acute conditions requiring immediate treatment, and routine admissions for planned investigations or treatments. The admission process involves welcoming the patient, collecting baseline medical information, orienting them to the hospital environment and services, and providing initial care and treatment. Discharge planning begins at admission and involves assessing the patient's needs, educating them and their family, arranging follow-up care and ensuring safe transition home.
