Significance

Length of stay (LOS) is influenced by many factors, but safe and effective care should result in shorter length of stay.

Start Dates

• Oct 2003 to Sept 2020 - each record is per ward stay. A hospital stay may have one or more individual ward stay (or records).
• Starting Oct 2020- each record is a continuous stay in any locations under Medicine service (or one Medicine episode) - see Definition of a Medicine Laptop Admission. If the patient is transferred to another service and comes back to Medicine service, this is a new record. A hospital stay may have one or more Medicine episodes.
