Fair, transparent ICU triage during bed shortages, disasters and surges, using priority models and SOFA-based protocols.
At the bedside
- 1
Escalate early
Inform the ICU consultant and hospital administrator when the last 1-2 beds are occupied; activate surge plans (HDU conversion, step-down beds, transfer agreements).
- 2
Assess every candidate the same way
Severity (SOFA, lactate, organ supports needed), reversibility, comorbidity and frailty, patient wishes. Do not use social worth, ability to pay, religion, caste or VIP status.
- 3
Apply priority categories
Priority 1: critically ill, needs life support, good likelihood of recovery, no limits on therapy. Priority 2: needs intensive monitoring, may need immediate intervention. Priority 3: critically ill but lower likelihood of recovery because of underlying disease; may receive therapy with limits. Priority 4: generally not appropriate (too well or irreversible/terminal).

During declared disasters use a crisis protocol
SOFA-based protocols (e.g. Ontario 2006): exclusion criteria, SOFA at 0, 48 and 120 h, colour codes (blue = palliative/ward, red = highest priority, yellow = intermediate, green = ward). Reassess at 48 h; patients failing to improve may be re-triaged.
- 5
Two senior clinicians and documentation
Triage decisions should involve two senior doctors where possible, be documented with reasons, and be communicated honestly to families. Offer the best possible alternative care (HDU, ward with NIV, palliative care).

Review continuously
Re-triage ICU occupants daily: step down those no longer needing ICU-level care to free beds; consider inter-hospital transfer.
ICU priority model (SCCM 2016)
| Priority | Description | Example |
|---|---|---|
| 1 | Life support needed, good chance of recovery, no limits | Septic shock from pneumonia in a previously well 40-year-old |
| 2 | Intensive monitoring, may need immediate intervention | Post-op major surgery at risk of bleeding |
| 3 | Critically ill, reduced likelihood of recovery, may have limits | Metastatic cancer with pneumonia, accepts NIV but not intubation |
| 4 | Generally not appropriate | Too well (stable, ambulant) or terminal/irreversible illness |

Bed shortage triage
Step 1 of ~6
Inform ICU consultant + administrator; activate surge plan
Based on Nates JL, Nunnally M, Kleinpell R, et al; Christian MD, Hawryluck L, Wax RS, et al. Educational use; follow local protocol.
Pathophysiology
Triage ethics balance utility (saving the most lives or life-years) with equity (fair process, equal respect). Transparent, pre-agreed criteria protect patients from bias and clinicians from moral distress.
Evidence
- SCCM 2016 recommends a priority-based admission model and use of objective severity scores to support (not replace) clinical judgement [Nates 2016].
- The Ontario pandemic triage protocol (Christian 2006) uses inclusion/exclusion criteria and serial SOFA scores; it informed many COVID-19 crisis standards of care.
Controversies
- SOFA-based triage can disadvantage patients with chronic disabilities or kidney disease (baseline creatinine); adjust for baseline organ dysfunction.
- Re-allocation (withdrawing ventilation from one patient to give another) is ethically and legally contentious; in India it requires extreme caution, senior involvement and documentation.
🇮🇳 India notes
- During COVID-19 surges Indian ICUs faced extreme scarcity; many hospitals now have written surge plans. DGHS 2023 lists 'low priority criteria in pandemic or disaster' as a reason not to admit.
- Never base triage on ability to pay. Government schemes (PM-JAY) cover ICU care in empanelled hospitals; help families access them.
