Description of intervention(s) / exposure
4 months duration (February to June 2007).
The installation of a new observation chart into 4 wards (two at The Canberra Hospital and two at Calvary Hosptial) which was colour coded for a modified early warning score.
The modified early warning score was utilised as a track and trigger system whereby if the score reached more than 4, a junior doctor was contacted by the bedside nurse to review and manage the patient within a 30 minute timeframe. The Medical Emergency Team (MET) could be contacted if the patient fulfilled standard MET criteria.
In order for the wards to be part of the pilot program, more than 50% of the healthcare workers needed to have undertaken a novel education package, COMPASS. This was a program that bought physiology to the bedside and informed people of the use of the SBAR communication tool. (Situation, Background, Assessment, Response).
The data will be collected from case records of the patients in a deidentified manner.

Early detection / Screening
Comparator / control treatment
The historical group was obtained from the same four wards during the same part of calendar in 2006 (Feb to June 2006)
During this time, there was no change to the usual patient care so that there was no added education on the deteriorating patient and the general observation chart was utilised with no colour coding and no track and trigger system. Patient review relied on either the nurse contacting the doctor with their concerns or calling for a Medical Emergency Team (MET) if they fulfilled the standard criteria for a MET.
The data will be collected from the patient's case records in a deidentified manner.
