Study Notes

Disaster Definition

A serious disruption of a community or society's functioning due to hazardous events interacting with exposure, vulnerability, and capacity.
Results in human, material, economic, and environmental losses and impacts.
UNISDR defines disasters.

Disaster Nursing Definition

The application of professional nursing skills to recognize and meet physical and emotional needs resulting from a disaster.
Nursing practiced in a situation with limited or unavailable supplies, equipment, facilities, and utilities.
Goal: To achieve the best possible level of health for individuals and the community impacted by the disaster.

Types of Disasters

Natural Disasters: Caused by natural or environmental forces, including earthquakes, floods, tornadoes, hurricanes, volcanic eruptions, ice storms, tsunamis, and other geological or meteorological phenomena.
- WHO defines "natural disaster" as the result of an ecological disruption or threat exceeding the affected community's adjustment capacity.
Man-Made or Anthropogenic Disasters: Caused by identifiable human actions, deliberate or otherwise, including biological and biochemical terrorism, chemical spills, radiological events, fire, explosions, transportation accidents, armed conflicts, and acts of war.
- Three Categories:
  - Complex Emergencies: Situations where populations suffer significant casualties due to war, civil strife, or political conflict.
  - Technological Disasters: Major industrial accidents, unplanned nuclear energy releases, and fires or explosions from hazardous substances directly and adversely affect large numbers of people, property, infrastructure, and economic welfare.
  - Disasters not caused by natural hazards but occurring in human settlements.

Disaster Onset, Impact, and Duration

Rapid-onset events: Earthquakes and tornadoes have short durations but sudden impacts on communities.
Sudden impact with advanced warning: Hurricanes and volcanic eruptions have sudden impacts but allow for evacuation and early response plans.
Sudden and unanticipated with rapid and prolonged impact: Bioterrorism attacks.
Gradual onset or chronic genesis: Droughts and famines, "creeping disasters" with prolonged onset.

Factors Influencing Disaster Impact

Nature of the event.
Time of day and year.
Health and age characteristics of the affected population.
Availability of resources.

Classification of Disasters in Disaster Science

Hazards: Potential threats to humans and their welfare.
Disasters: The actual occurrence of a hazard event.
Risk: The exposure of human value to a hazard, often measured as the product of probability and loss.

Classification of Disasters in Hospitals and Healthcare Facilities

Internal Disasters: Disrupting normal hospital function due to personnel injury or death, or damage to the facility itself (e.g., fire, power failure, chemical spill).
External Disasters: Do not affect hospital infrastructure but tax resources due to patient numbers or injury types (e.g., tornado causing injuries and deaths in the community).

Health Effects of Disasters

Premature deaths, illnesses, and injuries exceeding local healthcare system capacity.
Destruction of local healthcare infrastructure, hindering emergency response.
Disruption of routine health and mental healthcare services, leading to increased morbidity and mortality.
Environmental imbalances increasing the risk of communicable diseases and environmental hazards.
Psychological, emotional, and social well-being impacts, including fear, anxiety, depression, widespread panic, terror, and exacerbation of mental health problems.
Shortages of food and severe nutritional deficiencies.
Large population movements (refugees) burdening other healthcare systems and communities, increasing the risk of communicable diseases and health consequences associated with crowded living conditions.

Major Concerns about Nurse's Role in Disasters (Dr. Veenema)

Personal safety: Nurses want to ensure their own safety, as well as the safety of their loved ones and patients.
Clinical competence: Nurses want to be confident in their ability to handle emergencies effectively, including less common ones like radiation exposure or disease outbreaks.

The Disaster Continuum (Life Cycle of a Disaster Management Program)

Three major phases:
- Preimpact (before): Proactive planning to structure the disaster response.
- Impact (during): Actual implementation of the disaster plan.
- Postimpact (after): Stabilizing and returning the community to normal.
Basic phases or "life cycle" of a disaster management program (PMPRR):
- Preparedness: Proactive planning, evaluating potential vulnerabilities, and the propensity for a disaster to occur.
- Mitigation: Measures taken to reduce the harmful effects of a disaster by limiting its impact on human health, community function, and economic infrastructure.
- Response: Implementing the disaster plan, focusing on emergency relief, saving lives, providing first aid, minimizing and restoring damaged systems, and providing care and basic life requirements to victims.
- Recovery: Stabilizing and returning the community to normal, rebuilding, repairing, relocating, and providing physical, behavioral, and mental health interventions.
- Evaluation: Determining what worked, what didn't work, and identifying problems, issues, and challenges.

Disaster Planning

Addressing the problems posed by potential events.
Nurses' involvement in all phases of disaster planning is critical to ensure awareness and preparedness.
All possible eventualities should be considered, including sanitation needs, crowd management, psychosocial needs of vulnerable populations, and evacuation procedures.
Completion of disaster planning should result in a comprehensive disaster or "emergency operations plan."

Disaster Plan

A formal plan of action for coordinating healthcare agency staff's response in the event of a disaster.
Aims to provide prompt and effective medical care to maximize the number of people helped and minimize morbidity and mortality.
Objectives:
- Prepare staff and institutional resources for effective performance in disaster situations.
- Increase community awareness about sequential steps to take at individual and organizational levels.

Types of Disaster Planning

Agent-specific approach: Focuses on the most likely threats based on geographic location (e.g., hurricanes in Florida).
All-hazards approach: A conceptual model for disaster preparedness incorporating consistent disaster management components across all major events to maximize resources, expenditures, and planning efforts.

Nurses' Roles in Disaster Planning

Personal and professional preparedness.
Develop personal and family preparedness plans.
Be familiar with workplace and community disaster plans.
Maintain disaster training and CPR certifications.
Participate in mock disaster drills.

Problems, Issues, and Challenges in Disaster Planning

Anticipating communication issues.
Addressing operational issues related to effective triage, transportation, and evacuation.
Accommodating the management, security, and distribution of resources at disaster sites.
Implementing advanced warning systems and enhancing warning messages.
Enhancing coordination of search and response efforts.
Effective patient triage (prioritization for care and transport).
Establishing plans for equitable patient distribution to hospitals.
Patient identification and tracking.
Damage or destruction of healthcare infrastructure.
Management of volunteers, donations, and other large numbers of resources.
Organized improvisational response to system disruptions.
Encountering overall resistance (apathy) to planning efforts.

Hazard Identification, Vulnerability Analysis, and Risk Assessment

Hazard Identification: Determining events most likely to affect a community and making decisions about who or what to protect.
Vulnerability Analysis: Determining who is most likely to be affected, what property is most likely to be damaged or destroyed, and the community's capacity to deal with disaster effects. Collecting data regarding the susceptibility of individuals, property, and the environment to potential hazards to develop prevention strategies. Conducting a separate vulnerability analysis for each identified hazard.
Risk Assessment: Using the results of hazard identification and vulnerability analysis to determine the probability of a specified outcome from a given hazard affecting a community with known vulnerabilities and coping mechanisms (risk equals hazard times vulnerability).

Disaster Planning and Public Health Preparedness: Six Domains

Community resilience.
Incident management.
Information management.
Countermeasure and mitigation.
Surge management.
Biosurveillance.

Evaluating Capacity to Respond

A community's ability to withstand a disaster is directly related to the type and scope of available resources, communication systems, structural integrity of buildings and utilities, and the size and sophistication of its healthcare system.
Resources include both human and physical elements, such as organizations with specialized personnel and equipment.
Disaster preparedness involves assembling lists of healthcare facilities, medical and emergency responder groups, public works and civic departments, and volunteer agencies, including phone numbers and key contact personnel.

Core Preparedness Activities

Preparing a theoretical foundation for disaster planning.
Disaster planning is only as effective as the assumptions upon which it is based.
Core preparedness activities must go beyond routine practices.
Conducting a community needs assessment.
Identifying leadership and command posts.
Designing a local response for the first 72 hours.
Identifying and accommodating vulnerable populations.
Understanding state and federal assistance.
Identifying training and educational needs, resources, and personal protective equipment (PPE).
Planning for early damage assessment.

Evaluation of a Disaster Plan

Evaluating the disaster response plan's effectiveness and completeness by key personnel involved in the response.
Assessing the comprehension of individuals expected to execute the plan and their ability to perform duties.
Evaluating and reviewing the availability and functioning of equipment specified by the disaster plan on a systematic basis.
Methods for exercising the disaster plan include full implementation in an actual disaster and drills.
Drills can be staged as full-scale exercises using triaged victims and vast resources, or limited to a small segment of the disaster response, such as communications protocol or notification procedure drills.
