Awareness |

Risk mitigation |
· Food, drink, nap |
Recovery |
· 2h nap after night shift then stay awake |
List management |
· No operating 2200-0800 unless threat to life, limb or organ · Elective cases should be completed before 2200 |
Rostering |
· Aim no working > 12 hours. Definitely no working >16 hours. · 8 hours rest between shifts · Produce rosters well in advance to allow planning · Forward rotating shifts are the least disturbing (a.m. -> p.m. -> night) · Do not schedule staff for a.m. + p.m. + evening on call · Sufficient overlap between shifts for handover · Plan to manage absence due to fatigue · Document and monitor unrostered overtime |
Other |
· Travel reimbursement: if too tired to drive home · Rest facilities: for overnight staff · Monitor risk factors, fatigue and its consequences |
