Triage is done during disaster management to ensure treatment of casualties is done properly. What is true about triage done at the disaster site?

Correct Answer: A. Moribund patients receive the lowest priority

Triage at the disaster site operates on the principle of maximum benefit to the maximum number of casualties. Moribund patients (those with injuries incompatible with life, such as massive head trauma, severe burns >90%, or injuries requiring resources disproportionate to survival chance) receive the lowest priority (black tag) because allocating scarce resources to them would compromise the survival of salvageable patients. This is ethically justified under utilitarian ethics in mass casualty situations, where individual benefit is subordinated to collective survival. In India's disaster management framework (as per the Disaster Management Act 2005 and guidelines from the National Disaster Management Authority), triage protocols explicitly classify casualties into four categories: Immediate (Red), Delayed (Yellow), Minor (Green), and Expectant/Moribund (Black). The black-tagged patients receive comfort care only, not active resuscitation. This principle has been validated in major Indian disasters (2004 tsunami, 2015 Nepal earthquake response) where resource allocation based on salvageability significantly improved overall survival rates. The key discriminator is that moribund patients, by definition, have near-zero survival probability even with maximum intervention, making them the lowest priority in a resource-constrained environment.

Why the other options are wrong

B. Green labels are for those who need to be transported on priority — This is incorrect because green labels denote minor/walking wounded with injuries that are non-life-threatening and do not require immediate transport. These patients have the lowest transport priority and can often self-evacuate or wait for later transport. Red labels (immediate/critical) require priority transport. This is a common NBE trap that reverses the color-coding system to confuse students unfamiliar with triage protocols. C. Most commonly used system is three color code system — This is incorrect because the four-color code system (Red-Yellow-Green-Black) is the most widely used in modern disaster management, including India's NDMA guidelines and WHO recommendations. The three-color system (omitting black tag) is outdated and rarely used in contemporary practice. Some older or resource-limited settings may use three colors, but the four-color system is the standard, making this a factually incorrect statement. D. First come first treated basis — This is incorrect because triage explicitly rejects the 'first come, first served' principle in favor of severity-based prioritization. In disasters, the most critical patients (red tag) are treated first regardless of arrival order, while minor injuries (green tag) wait. This option represents a fundamental misunderstanding of triage philosophy and is a classic NBE trap testing whether students understand that triage overrides normal queue-based treatment.

High-Yield Facts

Mnemonics

TRIAGE Color Priority (START Protocol variant) Red = Immediate (life-threatening, salvageable) → treat first Yellow = Delayed (serious, stable) → treat second Green = Minor (walking wounded) → treat third Black = Moribund (expectant, comfort care) → lowest priority Memory hook: 'Red hot, Yellow warm, Green cool, Black gone' — reflects urgency and prognosis. Moribund = Lowest Priority (Utilitarian Logic) Massive injuries (incompatible with life) Over-resourced (would consume disproportionate resources) Rare survival (near-zero chance even with max intervention) → Therefore, lowest priority in mass casualty triage.

NBE Trap

NBE pairs "moribund patients" with "lowest priority" to test whether students understand utilitarian ethics in disaster management versus the intuitive (but incorrect) assumption that the sickest should be treated first. The trap is that students may confuse "sickest" with "highest priority," forgetting that in mass casualty situations, salvageability—not severity alone—determines priority.

Clinical Pearl

In the 2004 Indian Ocean tsunami response, hospitals that strictly adhered to black-tag protocols (withholding aggressive resuscitation from moribund patients) were able to save significantly more lives than those that attempted universal resuscitation. This real-world validation reinforces that triage is not about individual mercy—it is about collective survival under scarcity.
