Chapter 19: Community Preparedness: Disaster

and Terrorism


Chapter Highlights• History of public health nurses and disaster response

• Types of disasters

• Disaster management

• Public health response

• Role and responsibility of nurses in disasters

• Classification of agents

• Field response

• Skill building for field activity


Nursing Roles

• Nurses play an important role in all phases of disaster response.

• All practicing nurses should become familiar with disaster phases and their role during an event.

• Public health nurses practice principles of disaster response on a daily basis.


Question

Is the following statement True or False?

Disasters are considered events that require a swift, intense response on the part of existing community resources.


Answer

False

Rationale: Emergencies are considered events that require a swift, intense response on the part of existing community resources. Disasters are often unforeseen, serious, and unique events that disrupt essential community services and cause human morbidity and mortality that cannot be alleviated unless assistance is received from others outside the community.


Emergencies

• Emergencies are considered events that require a swift, intense response on the part of existing community resources.


Disasters

• Disasters are often unforeseen, serious, and unique events that disrupt essential community services and cause human morbidity and mortality that cannot be alleviated unless assistance is received from others outside the community.

• Disasters vary by the following points:

– The type of onset

– The duration of the immediate crisis

– The magnitude or scope of the incident

– The extent that the event affects the community


Three Types of Disasters

• Natural

• Accidental

• Terrorist attacks


Disaster Management

• Preimpact

• Impact

• Postimpact


Preparedness

• Although disasters do not occur with frequency, planning with vulnerability assessment can reduce the impact on the community.

• Identification of hazards

• Analysis of vulnerability

• Assessment of risk


Identification of Hazards

• The identification of all existing and potentially dangerous situations before disasters occur is the first step in planning for an effective response.

• The types and combination of hazards are unique to a community.


Analysis of Vulnerability

• Vulnerability analysis predicts who will be affected the most and identifies community resources that are available for a response.


Assessment of Risk

• Using the comprehensive data gathered from hazard identification and vulnerability analysis, the probability of adverse health effects due to a specific disaster can be calculated.

• This is often represented as a low, medium, or high risk.


National Response Framework

• Framework that guides how the nation conducts all-hazards incident response


Mitigation

• Mitigation is an effort to prevent identified risks from causing a disaster.

• Mitigation involves efforts to lessen the impact of a disaster by initiating measures to limit damage, disease, disability, and loss of life among the members of a community.


Question


All response begins at the state level, where the disaster management plan is implemented and responders are deployed.


Answer

False

Rationale: All response begins at the local level, where the disaster management plan is implemented and responders are deployed.


Response• Incident command system

– Common organizational structure implemented to improve emergency response

• National Incident Management System

– Structured, flexible framework that guides the response to disasters at all levels of governments, private companies, and nongovernmental organizations


Recovery

• Recovery is the stabilization of the community and the return of the disaster area to its previous status.


Adverse Health Effects After Any Kind of Disaster

• Continuing death, chronic illness, and/or disability

• Population shift if recovery is prolonged

• Contamination of food and water supplies, with an increased risk of infectious diseases

• Collapse of local and regional health care access

• Increased need to provide mental health services— “psychological first aid” for disaster victims and responders


Evaluation

• Foundation for evidence-based disaster response

• Following a thorough review of the responses, a final report is prepared with recommendations for improving emergency response in the future.


Roles of Nurses in Disaster Management

• Public health nurses as first responders

• Just in time training

• Field triage

• Point of distribution plans

• Personal protective equipment

• Documentation in a disaster

• Skill building for disaster response


Bioterrorism

• History

• Categories of bioterrorism agents

– Can be easily disseminated or transmitted from person to person

– Result in high mortality rates

– Have the potential for major public health impact

– Might cause public panic and social disruption, and require special action for public health preparedness


Detection of a Bioterrorism Event

• Anthrax

• Botulism

• Plague

• Smallpox

• Tularemia

• Viral hemorrhagic fevers


Chemical Disasters

• Unlike biological agents, which require an incubation period before symptoms appear, a chemical agent, when released, makes its presence known immediately through observation (explosion), self-admission (accidental), or the occurrence of rapidly emerging symptoms, such as burns, difficulty breathing, or convulsions.


Role of Nurses in a Chemical Disaster

• Stay or go, the evaluating factors include the following:

– The hazardous material involved

– The population threatened

– The time span involved

– The current and predicted weather conditions

– The ability to communicate emergency information


Shelter-in-Place

• Shelter-in-place is used for short duration incidents, when moving would result in a greater hazard, or it is impractical to evacuate.


Question


Evacuation, where people in a hospital or residential facility may be moved to another floor or area within the facility, may occur.


Answer

False

Rationale: Evacuation occurs when there is potential for massive explosions and fire as well as for long–duration events. Invacuation, where people in a hospital or residential facility may be moved to another floor or area within the facility, may occur.


Evacuation

• Evacuation occurs when there is potential for massive explosions and fire as well as for long–duration events.

• Invacuation, where people in a hospital or residential facility may be moved to another floor or area within the facility, may occur.


Radiological Disasters

• The health outcome depends on the following:

– The amount or dose of radiation absorbed

– The type of radiation

– The route of exposure

– The length of time exposed to the dose

• Dirty bombs


Public Health Disaster Response

• Scope and magnitude of response

• Communication during a disaster

• Recovery and after action evaluation
