Disaster Response

Intro & Principles - The First Alert

• Disaster Response: Coordinated actions taken during and immediately after a disaster to manage its adverse consequences.
• Primary Aims:
  • Save lives (⚕️), provide essential medical aid.
  • Minimize health impact (morbidity/mortality), restore vital services.
• Guiding Principles:
  • Speed, efficiency, multi-sectoral coordination.
  • Clear communication, community participation, ethical conduct.
• First Alert: The initial notification that a disaster has occurred or is imminent, triggering the formal response.
  • Immediate steps: Verification & Rapid Needs Assessment (RNA).
  • Activation: Emergency Operations Center (EOC), Incident Command System (ICS).
  • Mobilization: Designated resources & response teams.

⭐ The "Golden Hour" in trauma: critical first hour post-injury. Prompt medical intervention within this period significantly improves survival, vital in Mass Casualty Incidents (MCIs).

Triage & Field Care - Saving Lives Fast

• Triage: Rapidly sorting casualties by injury severity to optimize outcomes for the maximum number. Goal: "Do the most good for the most people."

• START Triage (Simple Triage And Rapid Treatment): Assessment <60 sec/person. Assesses RPM:

  • Respirations: Absent (after airway opening)? >30/min?
  • Perfusion: Capillary refill >2 sec? Absent radial pulse?
  • Mental Status: Unable to follow simple commands?
  • 📌 Mnemonic: "RPM-30-2-Can Do"

• Triage Categories & Colors:

  • 🔴 Red (I - Immediate): Life-threatening, salvageable (e.g., shock, airway compromise).
  • 🟡 Yellow (II - Delayed): Serious injuries, can wait (e.g., major fractures, stable abdominal wounds).
  • 🟢 Green (III - Minor): Walking wounded (e.g., minor lacerations, abrasions).
  • ⚫ Black (0 - Deceased/Expectant): Unlikely to survive or dead.

⭐ Triage is a dynamic process; patients must be reassessed periodically as their condition can change.

• Field Care Priorities:
  • Airway (open, clear), Breathing (assist if needed), Circulation (control major bleeding - direct pressure, tourniquet if appropriate).
  • Basic wound care, splinting fractures.
  • Rapid transport based on triage category.

Command & Control - Orchestrated Response

• Incident Command System (ICS): Standardized, on-scene, all-hazard incident management framework.
  • Core Principles: Common terminology, modular organization, unified command, manageable span of control.
  • Span of Control: Optimal 3-7 individuals per supervisor.
  • Key Sections: Command, Operations, Planning, Logistics, Finance/Admin (📌 C-FLOP: Command, Finance, Logistics, Operations, Planning).
• Emergency Operations Centre (EOC):
  • Central facility for strategic coordination, multi-agency response support, resource allocation, and information dissemination.
• Communication:
  • Inter-agency: Standardized protocols, interoperable systems (e.g., common radio frequencies).
  • Public Information Officer (PIO): Single point for accurate media and public communication.
• Logistics & Resource Management:
  • Acquisition, storage, transport, and distribution of essential resources (medical supplies, personnel, equipment).
  • Tracking systems for personnel and supplies.

⭐ The Incident Command System (ICS) emphasizes "Unity of Command," where each individual reports to only one designated supervisor during an incident response operation for clarity and accountability.

Public Health Post-Disaster - Aftermath Actions

• Rapid Health Assessment (RHA): Quickly assess health needs, damage, and available resources.
• Disease Surveillance:
  • Establish early warning systems for outbreaks (e.g., cholera, measles).
  • Monitor disease trends and identify vulnerable populations.
• WASH (Water, Sanitation, Hygiene):
  • Ensure safe water (min 15L/person/day).
  • Provide adequate sanitation (1 latrine per 20 people).
  • Promote hygiene practices.
• Nutrition Support:
  • Assess nutritional status, especially in children, pregnant women.
  • Implement supplementary feeding programs if needed.
• Vector Control: Implement measures against mosquitoes, flies.
• MHPSS: Provide mental health and psychosocial support.

⭐ Establish disease surveillance within 24-48 hours post-disaster to rapidly detect and control outbreaks.

High-Yield Points - ⚡ Biggest Takeaways

• Triage (e.g., START) is the cornerstone of mass casualty management; prioritize Red tags.
• Incident Command System (ICS) ensures coordinated response and clear chain of command.
• Rapid Needs Assessment quickly identifies critical requirements like shelter, food, and water.
• Effective communication and inter-agency coordination are vital for successful operations.
• Search and Rescue (SAR) focuses on locating survivors and providing immediate aid.
• Psychological First Aid (PFA) addresses acute distress in victims and responders.
• Safe water supply and sanitation are crucial to prevent secondary outbreaks post-disaster.
