4.4 Disaster Preparedness, Infection Surveillance & Institutional Emergency Protocols

Disaster Preparedness, Infection Surveillance & Institutional Emergency Protocols

Nurses occupy the vanguard of disaster response, infection prevention, and institutional crisis management. In Jamaica and across the wider Caribbean basin, healthcare institutions operate within an active tropical disaster corridor characterized by recurrent major hurricanes (Category 1 to 5), localized seismic faults (such as the Enriquillo-Plantain Garden Fault system), coastal storm surges, and emerging infectious disease outbreaks (e.g., Dengue, Chikungunya, Leptospirosis). Ensuring survival during mass casualty events demands mastery of triage algorithms, infection control surveillance, and emergency operations architectures.

Mass Casualty Incident (MCI) Triage: The START System

In routine emergency department triage, clinical priority is given to the sickest individual. In contrast, Mass Casualty Incident (MCI) Triage is governed by the utilitarian principle of disaster medicine: doing the greatest good for the greatest number of casualties with severely constrained resources.

The international standard for adult field and hospital diversion triage is the START (Simple Triage and Rapid Treatment) system, which assesses three physiological parameters—Respirations, Perfusion, and Mental Status (RPM)—in under 30 seconds per casualty:

Step 1: Direct all walking wounded to move to a designated holding area.
        --> Anyone able to follow this instruction is tagged GREEN (Minor / Walking Wounded).

Step 2: Assess RESPIRATIONS for remaining non-ambulatory casualties:
        - If NOT breathing: Open the airway manually.
          * Still apneic after repositioning? --> Tag BLACK (Expectant / Deceased).
          * Resumes spontaneous breathing?     --> Tag RED (Immediate).
        - If breathing spontaneously:
          * Respiratory rate > 30 breaths/min? --> Tag RED (Immediate).
          * Respiratory rate < 30 breaths/min? --> Proceed to Step 3 (Perfusion).

Step 3: Assess PERFUSION:
        - Radial pulse ABSENT or Capillary Refill > 2 seconds? --> Tag RED (Immediate).
          (Control active severe external hemorrhage immediately).
        - Radial pulse PRESENT and Capillary Refill <= 2 seconds? --> Proceed to Step 4 (Mental Status).

Step 4: Assess MENTAL STATUS:
        - Cannot follow simple commands (unconscious, confused, unresponsive)? --> Tag RED (Immediate).
        - Can follow simple commands ("squeeze my fingers", "open your eyes")?    --> Tag YELLOW (Delayed).

Pediatric Modification: JumpSTART Triage

Because pediatric cardiac arrests are predominantly respiratory in etiology, the JumpSTART protocol incorporates a critical modification: if an apneic infant or child has a palpable peripheral pulse after manual airway positioning, the rescuer delivers 5 rescue breaths (15 seconds). If breathing resumes, the child is tagged Red; if apnea persists, the child is tagged Black.

Hospital Disaster Preparedness in Jamaica & CARICOM Realities

Caribbean hospitals must maintain robust Hospital Disaster Emergency Operations Plans (HDEOP) to withstand recurring regional hazards. Under the Pan American Health Organization (PAHO) "Smart Hospitals" initiative, regional facilities integrate disaster resilience, water autonomy, and emergency electrical self-sufficiency.

The Incident Command System (HEICS)

During an institutional crisis, traditional hospital hierarchy is replaced by the Hospital Emergency Incident Command System (HEICS):

• Incident Commander: Single leader holding ultimate operational authority for crisis management.
• Safety Officer: Assesses hazardous conditions and has authority to halt unsafe clinical actions.
• Liaison Officer: Coordinates with external disaster agencies (e.g., Jamaica's Office of Disaster Preparedness and Emergency Management [ODPEM], Parish Disaster Committees, Jamaica Defence Force).
• Public Information Officer (PIO): Directs media communications and issues verified public notices.
• Operations Section: Delivers clinical care, triage, surgical intervention, and patient evacuation.
• Logistics Section: Secures potable water, food, fuel for backup diesel generators, and pharmaceuticals.
• Planning Section: Tracks ward census, forecasts resource burn-rates, and plans recovery.

Weather Emergencies: Hurricane Protocols

When a Category 4 or 5 tropical storm threatens, the nursing leadership executes pre-impact contingencies:

1. Surge Discharge: Rapid discharge of all Category I and stable Category II patients to expand bed capacity.
2. Critical Infrastructure Relocation: Move ICU, neonatal, and labor patients away from external glass windows into interior structural corridors.
3. Utility Reserves: Confirm 72-hour on-site potable water reserves (at least 20 liters per bed per day) and test emergency generator transfer switches.
4. Oxygen Safeguards: Secure all external compressed gas manifolds; anchor free-standing cylinders to walls with metal chains to prevent missile hazards during structural compromise.

Healthcare-Associated Infection (HAI) Surveillance & Evidence-Based Bundles

Healthcare-Associated Infections (HAIs) increase morbidity, prolong hospitalization, and escalate healthcare expenditures. Active infection surveillance requires infection control link-nurses to monitor infection rates and enforce evidence-based clinical care bundles:

1. Catheter-Associated Urinary Tract Infection (CAUTI) Bundle

• Strict Indications: Limit indwelling catheter placement strictly to acute urinary retention, accurate output monitoring in critically ill patients, perioperative use in specific surgeries, or end-of-life comfort.
• Aseptic Technique: Strict sterile insertion using a fenestrated drape, sterile gloves, and water-based lubricant.
• Closed Drainage Maintenance: Maintain an uninterrupted closed drainage system; keep the collection bag below the level of the bladder at all times to prevent retro-flow; keep the spigot off the floor.
• Daily Necessity Review: Re-evaluate the clinical need for the catheter every morning; remove immediately when clinical indication ceases.

2. Central Line-Associated Bloodstream Infection (CLABSI) Bundle

• Optimal Site Selection: Subclavian vein preferred over internal jugular; avoid femoral vein due to high bacterial colonization and thrombosis risk.
• Hand Hygiene & Skin Antisepsis: Vigorous hand hygiene before cannulation; skin preparation with >0.5% chlorhexidine gluconate in alcohol; allow the antiseptic to dry completely before insertion.
• Maximal Sterile Barrier Precautions: Full-body sterile drape on the patient; operator wears sterile gown, cap, mask, and sterile gloves.
• Daily Line Assessment: Review catheter necessity daily; prompt removal of unneeded lines.

3. Surgical Site Infection (SSI) Bundle

• Preoperative Decontamination: Patient chlorhexidine bathing the night before surgery.
• Hair Removal: Avoid razors (micro-abrasions increase infection risk); use electric clippers immediately prior to surgery if hair removal is essential.
• Antimicrobial Prophylaxis: Administer IV antibiotics within 60 minutes prior to surgical incision.
• Intraoperative Homeostasis: Maintain strict perioperative normothermia (>36.0°C) and normoglycemia.

Outbreak Management, Isolation Precautions & Institutional Emergency Codes

When an outbreak occurs on a ward (for example norovirus, influenza or a multidrug-resistant organism), the nurse:

1. Isolates or cohorts affected clients, using the contact, droplet or airborne precautions set out in Section 6.2.
2. Informs the infection prevention and control team and the nurse in charge at once.
3. Keeps a line list of affected clients and staff, with onset dates and symptoms.
4. Restricts transfers and non-essential visiting, as directed.
5. Reinforces hand hygiene and enhanced environmental cleaning, using hypochlorite for C. difficile and norovirus.
6. Excludes symptomatic staff from work according to policy, usually until 48 hours after diarrhoea and vomiting stop.

Institutional Emergency Codes & Fire Response

Colour codes let staff call for a coordinated response without alarming the public. They are not standardised across hospitals, so learn your facility's list. Common examples:

• Code Blue: Adult cardiopulmonary arrest or medical resuscitation emergency.
• Code Pink / Amber: Infant or child abduction from the facility.
• Code Red: Fire or smoke detection within the facility. Governed by the RACE operational sequence:
  • R – Rescue: Immediately move patients in immediate danger to a safe compartment.
  • A – Alarm: Activate the nearest fire pull station and broadcast the emergency code.
  • C – Confine: Close all doors, windows, and fire dampers to starve the fire of oxygen.
  • E – Extinguish / Evacuate: Extinguish small, localized fires using the PASS protocol (Pull the pin, Aim at the base of fire, Squeeze the handle, Sweep side-to-side); evacuate horizontally beyond fire barrier doors if containment fails.
• Code Yellow: Internal or external disaster; activation of the mass casualty incident plan.
• Code Orange: Hazardous material, hazardous chemical, or radioactive spill.
• Code Black: Bomb threat or suspicious unidentified explosive package.
• Code Silver: Active shooter, armed hostage incident, or violent weapon threat.
