  • Disasters are classified into natural or man-made (anthropogenic) disasters
  • Natural disaster:

_Account for more than 70% of all disasters

_They nclude the following:

 ||| Drought

 ||| Floods

 ||| Landslides

 ||| Tornadoes

 ||| Blizzards

_Poverty

_Aridity

_Settlement in areas prone to perennial flooding

_Settlement in areas with poor infrastructure and services

_Poorly constructed buildings.

## Phases of a national disaster management include the following:

  • Preparation

_Hazard Analysis

_Vulnerability Analysis that analyze factors that increase risks such as:

||| Number of people exposed to the hazard

||| Area covered by the hazard

||| Dose or intensity of power of the hazard

||| Time duration

||| Frequency

_Prevention and mitigation

||| Response planning by the institution

||| It includes formulation of policies and legislations that is required to prevent disasters

||| Resource mobilization

||| Public education

||| Prevention-elimination of hazards e.g. installation of a security wall.

||| Mitigation (which is reduction of destruction and disruption) e.g. construction of earthquake resistant buildings and air-bags in vehicles

_General preparedness

  • Warning phase
  • Impact
  • Emergency response
  • Recovery
  • Rehabilitation
  • Back to more preparation

## Disaster management – Hospital perspective

  • Every hospital should have a Disaster Management Plan
  • This plan should include:

_A well-constituted Hospital Disaster Management Team

_Provision of emergency equipment and drugs

_Communication equipment

_Means of transport

  • Pre-hospital organization in disaster management include:

_Consideration of security and safety of the medical team and victims

_Effective crowd control

_Preliminary assessment of the victims and taking the necessary life-saving action(s)

_Transport to the hospital:

||| Ambulance – reserved for the seriously injured victim

||| Helicopter or airplane (if available and required)

||| May make a decision to refer the victim directly to a consultant

  • Hospital organization in disaster management include:

_Establishment of the Command and Control Center under a senior medical officer

_The triage sieve:

||| Triage 1 for victims with life-threatening injuries but their lives can be saved by surgery

||| Triage II for victims whose injuries are so severe that their chance of survival is practically nil

||| Triage III for victims with minor injuries and they will probably recover even if the treatment is delayed. This group is operated last.
