19.1 Types of disasters and their impact on healthcare

Disasters, both natural and man-made, can wreak havoc on healthcare systems. From earthquakes to pandemics, these events strain resources and test our ability to respond. Understanding different disaster types helps healthcare workers prepare for the unexpected.

The impact on healthcare is profound, requiring surge capacity and careful resource allocation. Emergency management phases guide the response, from mitigation to recovery. Knowing these steps is crucial for effective disaster preparedness and response in healthcare settings.

1 of 3

• Natural disasters are caused by natural phenomena such as earthquakes, hurricanes, tornadoes, floods, wildfires, and tsunamis
• Can result in significant damage to infrastructure, loss of life, and displacement of populations
• Pandemics are global outbreaks of infectious diseases that spread rapidly across countries and continents (COVID-19, Spanish Flu)
• Pandemics can overwhelm healthcare systems, disrupt economies, and lead to widespread social and psychological impacts

Man-made Disasters and Mass Casualty Incidents

• Man-made disasters are caused by human actions, negligence, or technological failures such as industrial accidents, transportation accidents, and acts of terrorism (9/11 attacks, Chernobyl nuclear disaster)
• Mass casualty incidents are events that generate a high number of casualties, exceeding the local healthcare system's capacity to respond effectively
• Examples of mass casualty incidents include mass shootings, building collapses, and large-scale transportation accidents (Pulse nightclub shooting, Miami building collapse)
• These incidents require rapid triage, treatment, and transport of injured individuals to appropriate healthcare facilities

Public Health Emergencies

• Public health emergencies are events that pose a significant threat to public health and safety, requiring a coordinated response from healthcare providers and public health authorities
• Examples include outbreaks of infectious diseases (Ebola, Zika virus), contamination of food or water supplies, and environmental disasters (Flint water crisis)
• Public health emergencies may require implementing measures such as quarantine, isolation, mass vaccination campaigns, and risk communication to control the spread of disease and protect public health

Impact on Healthcare

Healthcare Surge Capacity and Resource Allocation

• Healthcare surge capacity refers to a healthcare system's ability to rapidly expand its resources and capabilities to meet increased demand during a disaster or emergency
• Involves mobilizing additional staff, equipment, supplies, and space to accommodate a sudden influx of patients
• Resource allocation becomes critical during disasters when demand exceeds available resources
• Triage protocols are used to prioritize patients based on the severity of their condition and likelihood of survival, ensuring limited resources are allocated to those who will benefit the most

Emergency Management and Disaster Response Phases

• Emergency management is the process of preparing for, responding to, and recovering from disasters and emergencies
• Involves developing plans, protocols, and systems to coordinate the activities of healthcare providers, emergency responders, and other stakeholders
• Disaster response typically follows four phases: mitigation, preparedness, response, and recovery
• Mitigation involves taking steps to prevent or reduce the impact of disasters before they occur (building codes, land-use planning)
• Preparedness involves developing plans, training personnel, and stockpiling resources to respond effectively when a disaster strikes
• Response involves activating emergency plans, mobilizing resources, and providing immediate assistance to affected populations (search and rescue, medical care, shelter)
• Recovery involves restoring essential services, rebuilding infrastructure, and providing long-term support to affected communities
