Key points
- Your job at night is <strong>safety + triage</strong>: stabilise, escalate early, document clearly.
- Use the registrar strategically: wake them for <strong>deterioration</strong>, <strong>uncertainty</strong>, or <strong>high-stakes decisions</strong>.
- Manage fatigue like a protocol: <strong>sleep stacking</strong>, caffeine timing, micro-breaks, and protected recovery.
Night shift mindset: you’re running a risk-control system
At night you are not “doing everything.” You are preventing avoidable harm until daylight resources return. That means: early recognition of deterioration, decisive escalation, and reducing errors through structure (checklists, clear handovers, and documentation).
When to wake the registrar (simple rule)
Wake the registrar if: <strong>(1) the patient is deteriorating</strong>, <strong>(2) you are uncertain and the decision is high-stakes</strong> (ICU, thrombolysis, ceilings of care), or <strong>(3) you’re being asked to make a decision beyond your competence</strong>. The threshold should be lower at 03:00, not higher.
The three common night traps (and how to avoid them)
Trap 1: anchoring (assuming it’s “just pain” or “just anxiety”). Trap 2: delayed escalation because you don’t want to bother seniors. Trap 3: documentation gaps that make morning review unsafe. Solve by using a standard structure: SBAR + objective vitals + clear plan.
Breaks are a safety intervention, not a luxury
If you skip breaks, you become the hazard. UK rules give workers an uninterrupted <strong>20-minute break</strong> if working more than 6 hours, and <strong>11 hours</strong> daily rest between working days. On nights, your break protects cognition.
Sleep stacking (fatigue-proofing that actually works)
If you have a night block coming, aim for a pre-night nap (90 minutes is ideal), then use caffeine early in the shift and avoid it in the final hours so you can sleep post-shift. Keep a “micro-routine” after nights: dark room, phone off, consistent wind-down.
First Night Shift Protocol (print this mentally)
1
Step 1: Map your escalation ladder
Know who the registrar is, who the consultant on-call is, how to contact critical care outreach, and how to summon help fast.
2
Step 2: Do a ‘systems scan’ early
Identify high-risk patients from handover (sepsis, DKA, GI bleed, new AF, post-op). Ask: who could crash?
3
Step 3: Standardise your assessment
Vitals, NEWS, exam, key labs, ECG if relevant. Avoid narrative-only assessments.
4
Step 4: Escalate early with SBAR
Situation, Background, Assessment, Recommendation. End with a clear ask: “Please review within 30 minutes.”
5
Step 5: Protect your cognition
Eat early, hydrate, plan one proper break. Use brief reset moments after stressful cases.
6
Step 6: Handover like a consultant would want
One-liner, what happened overnight, what’s pending, what’s the risk if not done by 10:00.
