Triage of a Mass Casualty Incident with Limited Resources

START triage categories:

• Patient A: Minor (green). Ambulatory, normal respiratory rate (18), radial pulse present, follows commands. Can be treated in a minimal care area.
• Patient B: Immediate (red). Not ambulatory, respiratory rate >30 (32), radial pulse present, cannot follow commands but localizes to pain (altered mental status). Requires immediate intervention.
• Patient C: Expectant (black) or Immediate depending on resources. Respiratory rate <10 (8), radial pulse absent, unresponsive. In START, if respiratory rate is <10, the patient is Immediate; however, if resources are overwhelmed and the patient is apneic after opening the airway, they may be Expectant. Here, the patient is breathing at 8, so per START, he is Immediate. But with limited resources and a high likelihood of mortality, he may be triaged as Expectant in a resource-constrained setting. The key is to follow the START algorithm: respiratory rate <10 = Immediate. However, many protocols allow for Expectant if resources are scarce. The question asks for START categories; strictly, Patient C is Immediate. But given the scenario's emphasis on limited resources, it's reasonable to discuss Expectant. I'll assign Immediate per START, but note the resource consideration.
• Patient D: Immediate (red). Ambulatory but confused (altered mental status), respiratory rate 22, radial pulse present. In START, ambulatory patients are initially Minor, but if they are confused, they are Immediate. The algorithm: if ambulatory, check mental status; if confused, Immediate. So D is Immediate.
• Patient E: Delayed (yellow). Not ambulatory, respiratory rate 20, radial pulse present, follows commands. He has active bleeding, which could upgrade to Immediate if uncontrolled, but per START, he is Delayed because he doesn't meet Immediate criteria (RR 20, pulse present, follows commands). However, active bleeding may require immediate control; but in triage, he is Delayed unless bleeding is life-threatening. The laceration with active bleeding might be controlled with direct pressure; if not, he could deteriorate. But per START, he is Delayed.

Summary:

• A: Minor
• B: Immediate
• C: Immediate (or Expectant if resources are overwhelmed)
• D: Immediate
• E: Delayed

Rationale: START uses Respiration, Perfusion, and Mental status (RPM). Patient B and D have altered mental status; B also has RR>30. Patient C has RR<10 and no radial pulse, indicating critical condition. Patient E is stable but requires treatment. Patient A is walking and stable.

With three Immediate patients (B, C, D) and one Delayed (E) who may need blood, plus limited resources, I must prioritize based on survivability and resource use.

• Patient B: RR 32, altered mental status, likely head injury or shock. Needs airway/breathing support and possibly blood. High priority for trauma bay.
• Patient C: RR 8, no radial pulse, unresponsive. Likely critical with poor prognosis. With limited resources, he may be Expectant; if resources allow, he needs airway and CPR. But with only two bays, using one for a patient with very low survival probability may not be the best allocation. Consider assigning him to Expectant and focusing on B and D.
• Patient D: Confused but ambulatory, RR 22, pulse present. Likely head injury or hypoxia. Needs evaluation and monitoring. Could be placed in a second bay.
• Patient E: Delayed but active bleeding; needs bleeding control and possibly blood. He can wait briefly but should be monitored.

Allocation:

• Use both trauma bays for B and D, as they have higher survivability and need immediate intervention.
• Patient C: If no improvement with simple airway maneuver, triage as Expectant and provide comfort care; do not allocate a bay.
• Patient E: Apply direct pressure and tourniquet if needed; place in a monitored waiting area; if blood products available, consider for transfusion after B and D.
• OR team: Reserve for B if surgical intervention (e.g., decompression) is needed; D may also need surgery but can wait.

Rationale: In mass casualty, allocate resources to those most likely to benefit. C has very low probability of survival; B and D have higher. E is stable but requires monitoring.

Ethical considerations:

• Justice and fairness: Allocate scarce resources based on objective criteria (e.g., survivability, resource needs) rather than bias.
• Beneficence and nonmaleficence: Act in the patient's best interest, but avoid futile care that consumes resources needed for others.
• Transparency: Decisions should be made according to a predetermined triage protocol (START) and documented.
• Duty to care: Even if a patient is Expectant, provide comfort care and reassess periodically.

Legal considerations:

• Standard of care: Follow hospital disaster protocols and START triage; deviations may require justification.
• Documentation: Record triage category, vital signs, interventions, and rationale for allocation. Note any changes in condition.
• Consent: In emergencies, implied consent applies; however, if patient is incapacitated, treat under emergency doctrine.
• Scope of practice: As a PT, you are assisting within your training; ensure you are not performing beyond your scope. Document that you acted under the direction of the ED charge nurse or incident commander.

Documentation:

• Use a triage tag or EHR disaster module.
• For each patient: name (if known), age, sex, triage category, vital signs, interventions, time, and disposition.
• For Expectant patient: document rationale for category, comfort measures provided, and reassessment intervals.
• For resource allocation: note which patients received trauma bay/OR/blood and why.
• Sign and date all entries; maintain confidentiality.
