    Study Notes

    Emergency Operations Plan (EOP) Components

    • EOP Activation Response: Determine where, how, and when the plan is activated.
    • Internal/External Communication Plan: Clear communication is essential, ensuring all involved parties are aware of the situation and necessary protocols. Example: During a disaster, hospitals may get assigned points for diverting ambulances, like Parkwest receiving 20 points and UT Med receiving 20 points, meaning ambulances are directed to other hospitals instead.
    • Coordinated Patient Care Plan: A plan outlining the organized approach to patient care during a disaster.
    • Security Plans: Involving local, state, and federal resources, such as the National Guard and local police, to ensure safety and security during an emergency.
    • Data Management Strategy: A comprehensive plan for managing data, including backup protocols to ensure the facility has accessible information even if the primary system fails. This is essential for tracking staffing and documentation, especially if using an electronic health record system.
    • Demobilization Response: A detailed plan for when to scale back resources and operations after a disaster, ensuring a smooth transition and avoiding unnecessary resource depletion.
    • Corrective Plan (Hotwash): A post-disaster review and discussion of all aspects of the plan and care provided, allowing for improvements and updates to future plans.
    • Practice Plan: Regular drills and simulations to prepare personnel for various disaster scenarios.
    • MCI Plan (Mass Casualty Incident): A specific plan addressing the management of mass casualties and morgue readiness.

    Initiating the EOP

    • Triage: Utilizing the SALT (Sort, Assess, Lifesaving Interventions, Treatment/Transport) method, patients are categorized based on the severity of their injuries:
      • Red/ Immediate: Life-threatening injuries requiring immediate attention (priority #1).
      • Yellow/ Delayed: Significant injuries requiring medical care, but can wait a few hours without immediate threat.
      • Green/ Minimal: Minor injuries, treatment can be delayed.
      • Black/ Deceased/ Expectant: Injuries are extensive, survival unlikely, even with extensive care.
      • White/ Involved: No obvious injuries.

    Nurse's Role in Disaster Response Plans

    • Nurses may be asked to perform tasks outside their usual scope of practice, depending on the situation.
    • Nurses may need to question care decisions if they believe they are not in the best interest of the patient.
    • Ethical dilemmas nurses might face: rationing care, consent, duty, confidentiality, resuscitation, and end-of-life decisions.

    Short-Term and Long-Term Psychological Effects of Disaster

    • Nurses should provide emotional support and information to patients and families affected by disasters.
    • Refer individuals for counseling as needed.
    • Encourage returning to normal activities.
    • Common psychological effects include anxiety, depression, compassionate fatigue, interpersonal conflicts, impaired performance, PTSD, migraine headaches, abdominal pain, and substance use disorders.

    Critical Incident Stress Management (CISM)

    • CISM is a program that aims to prevent and treat the emotional trauma that emergency responders may experience due to their work.
    • Components of CISM include:
      • Education: Preparing personnel for potential emotional stressors.
      • Defusing: A brief intervention shortly after an incident to help individuals process their experience.
      • Debriefing: A more in-depth discussion later, allowing for reflection and emotional processing.
      • Demobilization: Guidance on returning to regular work after an emergency.
      • Follow-up: Offering continued support and resources.

    Preparedness and Response: Onset of Outbreak, Epidemic, and Pandemic

    • Be vigilant for an increase in patients presenting with fever, respiratory, or gastrointestinal symptoms.
    • Identify any clusters of patients with the same unusual illness from a single location.
    • Note a significant increase in fatalities.

    Personal Protective Equipment (PPE)

    • Designed to protect healthcare workers from chemical, physical, biological, and radiologic hazards.
    • Environmental Protection Agency (EPA) Levels A-D:
      • Level A: Highest level of protection, including full, vapor-tight suits, gloves, boots, and self-contained breathing apparatus (SCBA).
      • Level B: Highest respiratory protection, but lesser skin and eye protection, using SCBA and chemical-restraint suits (not vapor-tight).
      • Level C: For airborne hazards, using air-purifying respirators, chemical-restraint coveralls, gloves, and boots.
      • Level D: Everyday work wear, with potential for additional PPE based on the situation.

    Decontamination

    • Essential to prevent secondary contamination.
    • First step: Removing clothing and jewelry, followed by rinsing with water.
    • Second step: Soap-and-water wash and rinse.
    • Consider the potential contamination of runoff water.

    • Blast wave effects:
      • Primary Injury: Resulting from the initial blast wave.
      • Secondary Injury: Caused by debris and shrapnel from the bomb.
      • Tertiary Injury: Resulting from pressure wave that causes the victim to be thrown.
      • Quaternary: Preexisting conditions exacerbated by the blast.
    • Blast Lung: Tearing of pulmonary tissue, air embolism, and VQ mismatch. Symptoms include dyspnea, hypoxia, tachypnea, apnea, cough, chest pain, and hemodynamic instability. Treatment may involve intubation, mechanical ventilation, and prone/left lateral positioning with hyperbaric oxygen therapy.
    • Tympanic Membrane Rupture: Most frequent injury after exposure to blast pressure. Symptoms include hearing loss, tinnitus, pain, dizziness, and otorrhea. Most TM ruptures heal spontaneously.
    • Abdominal Injury: Can result in internal bleeding and organ damage. Symptoms include bleeding, penetrating wounds, nausea, vomiting, abdominal pain, guarding, rebound tenderness, and rectal bleeding.
    • Head Injury: Often caused by falling debris or the blast itself, and a common cause of post-blast deaths.
    • Special Populations: Elderly (higher risk of fractures and comorbidities), pregnant women (risk of placental abruption), and individuals with mobility disabilities all require special consideration.
    • Laboratory Tests: CBCs, blood, urine, emesis, stool analysis, and potentially gastric lavage with chelating agents for radioactive substances.

    Acute Radiation Syndrome (ARS)

    • The hematopoietic system is the first to be affected.
    • Absolute lymphocyte count at 48 hours after exposure can predict the severity and outcome of ARS.

      • Bone marrow suppression (pancytopenia)
      • Determination of predicted survival
      • Phases of effects: Prodromal phase, latent phase, manifest illness phase, recovery phase, death
        • Probable survivors may have minimal or no initial symptoms and usually only require supportive care.
        • Possible survivors experience N/V, pancytopenia, needing blood product replacement, infection prevention, and supportive care.
        • Improbable survivors are acutely ill, presenting with N/V/D and shock.
        • Lethal doses cause neurological symptoms and death due to increased intracranial pressure.

    Emergency Operations Plan (EOP) Components

    • Activation response: Determines where, how, and when the plan is activated. Examples include major weather events.
    • Internal/External communication plan: Essential for clear communication during emergencies.
    • Coordinated patient care plan: Focuses on the organization and delivery of patient care during a disaster.
    • Security plans: Involve local, state, and federal agencies like the National Guard and local police department.
    • Data management strategy: Provides a backup system for documenting, tracking, and staffing during a disaster, especially when electronic health records are unavailable.
    • Demobilization response: A clearly defined plan for ending emergency operations, ensuring resources are not unnecessarily exhausted.
    • Corrective plan: A "hotwash" or debriefing to analyze and update the EOP after an event.
    • Practice plan: Regular drills to practice the EOP and anticipated resources like food and water.
    • MCI plan (Mass Casualty Incident): Planning for managing mass casualties and morgue readiness.

    Initiating the EOP

    • Triage: A system for categorizing patients based on the severity of their injuries to prioritize care.
      • Red/Immediate: Life-threatening injuries requiring immediate intervention. Examples include sucking chest wounds, airway obstruction, shock, pneumothorax, and significant burns.
      • Yellow/Delayed: Significant injuries requiring medical care but can wait hours without immediate threat to life. Examples include soft tissue injuries, fractures, and wounds requiring surgery.
      • Green/Minimal: Minor injuries that can wait hours to days for treatment. Examples include upper extremity fractures, minor burns, sprains, and minor lacerations.
      • Black/Expectant: Extensive injuries with minimal chance of survival. Examples include unresponsive patients with penetrating head wounds, high spinal cord injuries, cardiac arrest, or severe burns.
      • White/Involved: Patients with no obvious injuries.
      • SALT: A rapid assessment and sorting protocol: Sort, Assess, Lifesaving interventions, Treatment/Transport.

    Nurse's Role in Disaster Response Plans

    • Nurses may be asked to perform tasks outside their usual scope of practice depending on the needs of the situation.
    • Nurses may have to question decisions regarding patient care, particularly regarding ethical considerations.
    • Common ethical dilemmas encountered by nurses: rationing care, consent, duty to care, confidentiality, resuscitation, and assisted suicide.

    Psychological Effects After a Disaster

    • Nurses should provide emotional support, information, and refer to outside resources for counseling.
    • Common psychological effects include: anxiety, depression, compassionate fatigue, interpersonal conflicts, impaired performance, PTSD, migraine headaches, abdominal pain, and substance use disorders.

    Critical Incident Stress Management (CISM)

    • CISM aims to prevent and treat the emotional trauma that emergency responders experience.
    • CISM components: education, defusing, debriefing, demobilization, and follow-up.

    Preparedness and Response

    • Healthcare providers should be aware of potential attacks using toxic or infectious agents.
    • Onset of an outbreak, epidemic, or pandemic is often characterized by unusual increases in patients seeking care for fever, respiratory, or gastrointestinal symptoms.

    Personal Protective Equipment (PPE)

    • PPE protects healthcare workers from chemical, physical, biological, and radiological hazards.
    • Environmental Protection Agency (EPA) categorizes protective wear into four levels:
      • Level A: Highest level of protection for respiration, skin, eyes, and mucous membranes. Includes fully encapsulated, vapor-tight suits, gloves, boots, and self-contained breathing apparatus (SCBA).
      • Level B: High respiratory protection with lesser skin and eye protection. Includes SCBA and chemical-restraint suits, but not vapor-tight.
      • Level C: Protection for airborne hazards. Includes air-purifying respirators, chemical-restraint coveralls, gloves, splash-proof gear, and boots.
      • Level D: Everyday wear like scrubs or uniforms. Additional PPE like gloves and masks might be necessary depending on the situation.

    Decontamination

    • Decontamination removes or neutralizes contaminants to prevent secondary contamination.
    • Decontamination is crucial for both patients and personnel before entering the emergency department.
    • Decontamination steps include removing clothing and jewelry, rinsing with water, and washing with soap and water.

    ### Natural Disasters

    • Natural disasters like tornadoes, hurricanes, floods, earthquakes, and volcanic eruptions can pose significant health risks.
    • Potential issues include communication loss, lack of food and water, exposure to elements, medication loss, sanitation challenges, and utility outages.

    Weapons of Terror: Blast Injury

    • Explosives commonly used in attacks include pipe bombs, Molotov cocktails, fertilizer bombs, and dirty bombs.
    • Blast waves have four effects:
      • Primary injury: From the initial blast wave.
      • Secondary injury: From debris, projectiles, or shrapnel.
      • Tertiary injury: From the pressure wave causing victims to be thrown.
      • Quaternary injury: From preexisting conditions exacerbated by the blast.
    • Blast lung: Tearing of pulmonary tissue leading to hemorrhage, air embolism, and ventilation/perfusion mismatching.
    • Tympanic membrane rupture: Common injury from blast waves.
    • Abdominal injuries: Internal bleeding, organ damage, and penetrating wounds.
    • Head injuries: Most common cause of death after blasts caused by falling debris or the blast itself.
