Fatigue Assessment Matrix

The fatigue assessment matrix was developed as part of the Safer Nursing 24/7 project, using data from the 2016-20017 nationwide survey of registered and enrolled nurses,  and follows the approach used in the Australian Medical Association National Code of Practice – Hours of Work, Shift Work and Rostering for Hospital Doctors.  The matrix can be used to assess the fatigue-related risk associated with a particular roster.  Higher matrix scores predicted higher likelihood of fatigue-related outcomes.  The matrix matrix is scored on work in the last 7 days and summarised below and a spreadsheet is provided for download.
