Early warning system/score
See 'track and trigger system' below.

18:00 to 23:59.

Glasgow Coma Score
A method of assessing the level of consciousness of a patient.

Levels of care

Patients whose needs can be met through normal ward care in an acute hospital.

Patients at risk of their condition deteriorating, or those recently relocated from higher levels of care, whose needs can be met on an acute ward with additional advice and support from the critical care team.

Patients requiring more detailed observation or intervention including support for a single failing organ system or postoperative care and those “stepping down” from higher levels
of care.

Outreach service
A service that: averts admissions by identifying patients who are deteriorating; enables early discharges and shares critical care skills 10.

Track and trigger system

Unselected medical emergency admissions
Patients admitted as an emergency whose illness cannot immediately be identified.
