Youngest Hospital Discharge Age: Data Not Available

The provided context does not mention the youngest patient ever discharged from a hospital, so this question cannot be answered from the given source.

Such records are typically not publicly tracked in a centralized database. Extreme prematurity survivals (e.g., infants born at 21–22 weeks gestation) are occasionally reported in medical literature and news, but a definitive global "youngest discharge" record does not exist.
