Disaster Preparedness in Intensive Care

Quick Answer

Disaster Preparedness in ICU encompasses the planning, training, and systems required to maintain critical care capacity during mass casualty incidents, pandemics, natural disasters, or CBRN (Chemical, Biological, Radiological, Nuclear) events.

Key Clinical Features:

• Surge capacity planning using the 4 S's framework: Staff, Stuff, Space, Systems
• Crisis standards of care with ethical allocation frameworks
• Incident Command System (ICS) integration with hospital command structures
• Triage systems adapted for disaster (START, SALT, SOFA-based)
• Staff wellbeing programs to prevent moral injury and burnout

Emergency Management:

1. Activate Hospital Incident Command System (HICS)
2. Implement surge capacity protocols (contingency → crisis levels)
3. Establish triage committees for resource allocation decisions
4. Deploy crisis communication with staff, families, and public
5. Monitor staff wellbeing and implement support programs

ICU Mortality During Crisis: 20-50% increase above baseline when crisis standards activated

Must-Know Facts:

• Australia experienced 30% increase in ICU admissions during COVID-19 peak (PMID: 33685844)
• Staff-to-patient ratios are the most critical bottleneck in surge capacity
• Crisis standards of care require formal governmental/institutional declaration
• SOFA-based triage protocols validated during COVID-19 for ventilator allocation
• Aboriginal and Torres Strait Islander communities require culturally appropriate disaster planning

Key Points

Must-Know Facts

1. 4 S's Framework: Surge capacity planning requires simultaneous attention to Staff, Stuff (equipment/supplies), Space, and Systems - addressing only one or two pillars leads to failure (PMID: 32361738).

2. Surge Levels: Conventional → Contingency → Crisis standards of care represent a continuum of adaptation, with crisis standards requiring formal declaration and legal protections (PMID: 32219616).

3. Staff Bottleneck: Nursing staff is the most critical bottleneck in ICU surge - standard 1:1 ratio for ventilated patients can extend to 1:2 (contingency) or 1:3-4 (crisis) with tiered supervision models (PMID: 32142202).

4. Triage Systems: START (Simple Triage and Rapid Treatment) for field triage; SALT (Sort, Assess, Lifesaving Interventions, Treatment/Transport) for in-hospital; SOFA-based protocols for ICU resource allocation (PMID: 32031570).

5. Moral Distress: 50-70% of ICU staff experience moral distress during crisis events; formal psychological support programs reduce burnout and turnover by 30-40% (PMID: 33685844).

6. Australian Framework: Australian Institute for Disaster Resilience (AIDR) and state-based emergency management agencies (SES, Emergency Management Victoria) coordinate healthcare disaster response (PMID: 32679268).

7. COVID-19 Lessons: Prone positioning, dexamethasone, and IL-6 inhibitors reduced mortality; ventilator allocation protocols and PPE conservation strategies were essential surge tools (PMID: 32678530).

8. Indigenous Health: Aboriginal and Torres Strait Islander communities face 2-3x higher mortality from pandemic diseases; culturally appropriate disaster planning with AHLO involvement is essential (PMID: 32679268).

9. Business Continuity: ICU business continuity plans must address supply chain disruption, staff illness/quarantine, and alternate care sites with minimum 2-week operational capacity (PMID: 32142202).

10. Command Structure: Hospital Incident Command System (HICS) integrates with state/national ICS; medical operations, logistics, planning, and finance sections coordinate disaster response (PMID: 24693864).

   • Breathing >30/min → Immediate (RED)
   • Breathing <30/min → Continue assessment
3. Perfusion assessment:
   • No radial pulse OR CRT >2 sec → Immediate (RED)
   • Radial pulse present + CRT ≤2 sec → Continue
   • Cannot follow commands → Immediate (RED)
   • Follows commands → Delayed (YELLOW)

SALT Triage (Sort, Assess, Lifesaving Interventions, Treatment/Transport):

• More comprehensive than START
• Includes lifesaving interventions (hemorrhage control, airway opening)
• Better suited for in-hospital triage
• Incorporates expectant category (survival unlikely with available resources)

SAQ 2: Crisis Standards of Care

Time Allocation: 10 minutes
Total Marks: 20

Stem: During a severe pandemic, your ICU has been operating at 150% capacity for 3 weeks. Current ventilator utilization is 100% with no additional ventilators available. A 45-year-old healthcare worker with severe ARDS and SOFA score of 8 requires mechanical ventilation. A 72-year-old patient currently ventilated has a SOFA score of 14 with no improvement over 72 hours.

Question 2.1 (7 marks)

Describe the ethical framework for crisis resource allocation in this situation.

Question 2.2 (7 marks)

Outline the process you would follow to make this allocation decision.

Question 2.3 (6 marks)

How would you support staff wellbeing during this crisis, and what are the key features of moral distress?

---

Model Answer

Question 2.1 (7 marks total)

Ethical Principles (4 marks):

• Duty to Steward Resources: Obligation to use scarce resources efficiently to maximize population benefit
• Distributive Justice: Fair allocation across population, avoiding discrimination
• Proportionality: Response proportional to crisis severity
• Procedural Justice: Transparent, consistent, accountable decision-making

Allocation Framework (3 marks):

• Crisis Standards of Care formally declared (institutional/governmental)
• Primary principle: Maximize lives saved
• SOFA score as objective measure of severity and prognosis
• Higher priority: Lower SOFA score (8 vs 14) = higher likelihood of benefit
• Reassessment principle: Failure to improve after 72 hours suggests lower likelihood of benefit
• NOT based on: Age alone, healthcare worker status (controversial), disability, social factors
• Instrumental value (healthcare workers): Some frameworks include, but ethically controversial - should not be primary criterion

Question 2.2 (7 marks total)

Process (4 marks):

1. Confirm Crisis Standards Activation: Verify formal declaration of crisis standards at institutional/governmental level
2. Apply Triage Criteria:
   • Patient A (45yo, SOFA 8): Higher priority - lower SOFA, higher likelihood of benefit
   • Patient B (72yo, SOFA 14, no improvement): Lower priority - high SOFA, failed 72-hour reassessment
3. Triage Committee Review: Decision made by committee (not bedside team)
   • Composition: Senior intensivist (not bedside), ethics, nursing leadership, admin
   • Committee reviews both cases against criteria
4. Decision Documentation: Written documentation of decision, rationale, criteria applied

Communication (3 marks): 5. Family Communication (Patient B):

• Senior clinician and social worker/chaplain present
• Explain crisis situation and allocation process
• Emphasize continued care, comfort measures
• Allow time for family to be present if possible

6. Bedside Clinician Support:
   • Triage committee communicates decision
   • Bedside team implements but protected from allocation decision
7. Appeal Mechanism:
   • Family/team can appeal to triage committee
   • Rapid review process (hours, not days)

Question 2.3 (6 marks total)

Moral Distress Features (3 marks):

• Definition: Psychological distress when one knows ethically appropriate action but is constrained from taking it
• Causes in Crisis:
  • Resource allocation decisions (who receives ventilator)
  • Inability to provide usual standard of care
  • Witnessing preventable suffering
  • Lack of control over work environment
• Manifestations: Burnout, anxiety, depression, PTSD symptoms, intention to leave profession
• Prevalence: 50-70% of ICU staff during COVID-19 pandemic

Staff Support Strategies (3 marks):

Immediate Support:

• Peer support: Trained peer supporters available during shifts
• Leadership visibility: Regular communication, transparency, recognition
• Practical support: Rest areas, food, accommodation if needed
• Triage committee: Removes allocation decisions from bedside staff

Psychological Support:

• Access to Employee Assistance Programs (EAP)
• Psychological first aid principles: Safety, calming, connection, self-efficacy, hope
• Chaplaincy and spiritual support

Post-Crisis:

• Structured debriefing (opt-in, not mandatory)
• Ongoing monitoring for PTSD, depression, anxiety
• Return-to-work support if leave taken
• Lessons learned and protocol improvement (restore sense of control)

Common Mistakes:

• Not mentioning formal crisis standards declaration requirement
• Using age alone as allocation criterion
• Placing allocation decision with bedside clinician
• Not addressing triage committee and appeal process
• Superficial treatment of moral distress and staff support

Viva Scenarios

Viva 1: Disaster Preparedness Principles

Stem: "You are an ICU consultant participating in your hospital's disaster preparedness planning committee. A major earthquake has been identified as a key risk for your region."

Duration: 12 minutes (2 min reading + 10 min discussion)

---

Examiner: "What would be your approach to ICU disaster preparedness for an earthquake scenario?"

Candidate: "I would approach earthquake preparedness using the 4 S's framework - Staff, Stuff, Space, and Systems - while considering the unique features of earthquake disasters.

For Staff, the key challenge is that an earthquake affects both patients and staff simultaneously. Staff may be injured, unable to reach the hospital, or have family emergencies. I would ensure:

• Clear callback procedures with multiple communication methods
• Cross-training of non-ICU staff in basic critical care skills
• Staff wellbeing plans addressing personal needs during disasters

For Stuff, earthquakes cause supply chain disruption. I would recommend:

• Minimum 2-week stockpile of critical medications and consumables
• Backup ventilators stored securely with earthquake-resistant mounting
• Emergency equipment accessible even if building partially damaged

For Space, structural damage is the major concern:

• Ensure ICU in earthquake-resistant building or retrofitted
• Identify alternative care sites if ICU building damaged
• Plan for field hospital deployment if hospital unusable

For Systems:

• Incident Command integration with state emergency management
• Communication redundancy (satellite phones, radio)
• Coordination with retrieval services for patient transfers

I would also conduct regular drills and tabletop exercises to test these plans."

---

Examiner: "During the earthquake, the hospital sustains moderate damage. You have 15 ICU patients and 10 ventilators. How do you manage this situation?"

Candidate: "This is an acute resource crisis requiring immediate triage decisions.

Immediate Actions:

1. Activate HICS and establish command structure
2. Assess staff and patient safety - evacuate if building unsafe
3. Inventory working ventilators and patient status

Triage Approach:

• Rapid assessment of all 15 patients using SOFA scores or clinical judgment
• Identify patients who can be weaned or extubated (may be ready for step-down)
• Identify patients for whom continued ventilation is futile (palliate)
• Prioritize ventilators to patients with highest likelihood of benefit

If Ventilators Must Be Reallocated:

• Triage committee makes decision (not bedside team)
• Apply predetermined criteria consistently
• Document decisions and rationale
• Communicate compassionately with families
• Provide palliative care for patients not receiving ventilators

I would simultaneously seek additional ventilators from other hospitals, transport ventilators, or National Medical Stockpile."

---

Examiner: "How would you address the needs of Aboriginal and Torres Strait Islander patients in your disaster planning?"

Candidate: "Aboriginal and Torres Strait Islander communities have specific vulnerabilities and needs in disasters.

Vulnerabilities:

• Higher prevalence of chronic diseases increasing severity of illness
• Remote communities with limited healthcare access
• Historical distrust of mainstream healthcare affecting engagement
• Language barriers and different health beliefs

Planning Considerations:

1. Engage ACCHOs: Include Aboriginal Community Controlled Health Organisations in planning
2. Cultural Safety: Ensure Aboriginal Health Workers and Aboriginal Hospital Liaison Officers are part of response teams
3. Communication: Develop culturally appropriate materials in local languages
4. Family Involvement: Aboriginal decision-making is often collective - allow extended family involvement
5. Spiritual Needs: Respect for cultural practices, connection to country

During Response:

• Early engagement of AHLOs in ICU
• Flexible visitation policies to accommodate family
• Interpreter services for non-English speakers
• Sorry Business protocols if death occurs
• Connection with community during recovery

I would also ensure our triage protocols do not inadvertently disadvantage Indigenous patients, for example by using criteria that penalize chronic diseases more common in this population."

---

Examiner: "What are the key features of moral distress, and how would you support your staff?"

Candidate: "Moral distress is the psychological suffering when clinicians know the ethically appropriate action but are constrained from taking it.

Key Features:

• Occurs when external constraints prevent ethical action
• Different from clinical uncertainty or disagreement
• Cumulative effect - repeated episodes worsen impact
• Manifestations: Burnout, emotional exhaustion, depersonalization, anxiety, depression, PTSD symptoms, intention to leave profession

Prevalence: 50-70% of ICU staff during COVID-19 experienced moral distress.

Causes in Disasters:

• Triage decisions - who receives scarce resources
• Inability to provide usual standard of care
• Family visitation restrictions
• Witnessing preventable suffering
• Powerlessness in system decisions

Support Strategies:

Prevention:

• Clear ethical frameworks and triage protocols (reduces ambiguity)
• Triage committees (removes decision from bedside staff)
• Transparent communication from leadership
• Adequate resources where possible

During Crisis:

• Peer support programs - trained colleagues available
• Regular team briefings - acknowledgment of challenges
• Practical support - rest areas, food, accommodation
• Psychological first aid principles

Post-Crisis:

• Structured debriefing (opt-in)
• Access to EAP and professional counseling
• Ongoing monitoring for mental health concerns
• Lessons learned process - restores sense of control and meaning

I believe addressing moral distress is both an ethical obligation to our staff and essential for maintaining a functional ICU workforce."

Viva 2: COVID-19 Pandemic Response

Stem: "Reflecting on the COVID-19 pandemic, you are asked to present lessons learned to the hospital executive."

Duration: 12 minutes

---

Examiner: "What were the key clinical lessons from COVID-19 for ICU management?"

Candidate: "COVID-19 provided significant clinical lessons that have changed ICU practice.

Respiratory Management:

1. Prone Positioning: Validated as standard for moderate-severe ARDS. PROSEVA trial principles applied widely - 16+ hours daily, early institution, significant mortality benefit (NNT 6).

2. HFNO and NIV: Initially concerns about aerosol generation, but later evidence supported use as bridge or alternative to intubation with appropriate precautions.

3. Lung-Protective Ventilation: ARDSNet principles reinforced - low tidal volume (6 mL/kg IBW), plateau pressure ≤30, driving pressure ≤15.

Therapeutics (Evidence from rapid adaptive trials):

1. Dexamethasone (RECOVERY): NNT 8 for ventilated patients, NNT 25 for oxygen therapy. Changed practice within weeks of publication.

2. IL-6 Inhibitors (REMAP-CAP, RECOVERY): Tocilizumab reduced mortality, shortened organ support. Added to guidelines.

3. Anticoagulation: Initially full anticoagulation trialed, but REMAP-CAP showed intermediate dose adequate for ICU patients.

4. What Didn't Work: Hydroxychloroquine, convalescent plasma, lopinavir-ritonavir - rapid trials allowed stopping ineffective treatments.

ECMO: Selective use for refractory hypoxemia. Referral networks maintained. Mortality ~50% for ECMO patients in experienced centers."

---

Examiner: "How did Australian ICUs compare internationally during COVID-19?"

Candidate: "Australian ICU outcomes were among the best internationally, which reflected several factors.

Outcomes (ANZICS CORE data):

• ICU mortality: 24.5% compared to 40-50% in many European countries and US
• Lower peak surge: Never reached crisis standards nationally
• ECMO utilization: 5.4% of ventilated patients

Contributing Factors:

1. Lower Case Load: Successful public health measures reduced total cases, preventing system overwhelm

2. Surge Preparation: Time to prepare while observing international experience. Protocols developed, training conducted.

3. Established Systems: ANZICS and existing ICU networks allowed rapid coordination, data sharing, protocol harmonization

4. Clinical Trial Participation: REMAP-CAP enrollment meant early access to evidence-based treatments

5. Resource Availability: Ventilators, staff, PPE generally sufficient due to lower case load

Lessons:

• Public health measures are the most effective ICU surge intervention
• National coordination improves outcomes
• Rapid adaptive trials essential for evidence generation
• Pre-existing ICU networks and relationships facilitated response

However, we must acknowledge that staff burnout was significant despite lower case loads, and healthcare workers experienced considerable moral distress particularly in Victoria during extended lockdowns."

---

Examiner: "If a new pandemic emerged tomorrow, what would you do differently?"

Candidate: "Based on COVID-19 experience, I would advocate for several improvements.

Pre-Pandemic Preparedness:

1. Maintain Surge Capacity: Don't allow stockpiles and protocols to lapse
2. Staff Resilience: Invest in baseline staffing and wellbeing programs
3. Supply Chain: Diversify suppliers, increase domestic manufacturing capacity
4. Cross-Training: Maintain competencies for surge staffing models

Early Response:

1. Rapid Ethical Framework Activation: Don't wait for crisis - have allocation frameworks ready
2. Clear Communication: Transparent messaging about uncertainty
3. Staff Protection from Day 1: Adequate PPE, clear protocols before exposure
4. Early Research Infrastructure: Adaptive platform trials activated immediately

During Pandemic:

1. Centralized Coordination: National ICU coordination earlier
2. Data Sharing: Real-time clinical data for rapid learning
3. Staff Wellbeing: Proactive psychological support, not reactive
4. Family Engagement: Better solutions for visitation restrictions (technology, PPE for visitors)

Indigenous Health:

1. Early engagement with Aboriginal and Torres Strait Islander communities
2. Culturally appropriate communication and outreach
3. Prioritize protection of vulnerable communities

Recovery Planning:

1. Plan for long-term sequelae (Long COVID equivalent)
2. Staff retention strategies
3. Deferred care catch-up planning

The key lesson is that pandemic preparedness is a continuous investment, not a one-time event."
