Discharge refers to the release of a patient from a healthcare facility, and there are several types. The most common types include medical discharge, where a patient is released after treatment, and voluntary discharge, where a patient chooses to leave against medical advice. Another type is administrative discharge, which occurs when a patient is discharged due to non-compliance with hospital rules or policies. Additionally, transfer discharge happens when a patient is moved to another facility for further care. Each type serves specific circumstances and ensures proper patient management.
