In community health practice, assessing a casualty effectively is a critical skill that can determine the outcome of emergency care. Community health professionals in Kenya often work in resource-limited settings where rapid, accurate assessment at the scene is essential for timely intervention. This chapter focuses on conducting a scene size-up, which is the initial evaluation of the environment and circumstances surrounding the casualty. Understanding how to systematically assess the scene ensures the safety of both the responder and the victim, and guides appropriate response actions.
Conducting a scene size-up is the first step when arriving at an emergency involving a casualty. It involves evaluating the safety and dynamics of the scene, understanding the cause of injury, the severity of the situation, and determining the resources required. In Kenya, where community health workers may be first responders in rural or urban environments, mastering scene size-up helps prevent further harm and ensures efficient use of limited emergency resources.
Scene safety is the foremost priority in any emergency response to protect the responder, bystanders, and the casualty. In Kenyan community health settings, hazards can be environmental, biological, or human-induced, and identifying these early can prevent secondary injuries.
Environmental hazards include factors such as traffic, unstable structures, fire, water bodies, or electrical wires. For example, at a road traffic accident near a busy Nairobi highway, assessing oncoming traffic flow and ensuring a safe working space for casualty care is essential before approaching the victim.
Biological hazards include exposure to bloodborne pathogens, infectious diseases, or contaminated materials. Community health workers attending to casualties at a market or informal settlement must be alert to risks such as HIV, Hepatitis B, or COVID-19, and use appropriate personal protective equipment (PPE).
Some scenes may involve hostile individuals or crowd disturbances. For instance, during a conflict in a county government office, responders must evaluate the possibility of aggressive behavior and coordinate with security personnel before intervening.
Before engaging with the casualty, responders must confirm the availability and proper use of PPE such as gloves, masks, and eye protection to reduce exposure to hazards and maintain infection control.
Understanding the mechanism of injury provides insight into the forces involved and potential internal damage, guiding prioritization of care. This knowledge is especially important in Kenya’s diverse environments, from urban road accidents to agricultural injuries.
The MOI refers to the physical process that caused the injury, such as blunt force trauma, penetrating injury, or burns. Knowing the MOI helps predict injury patterns even before a detailed clinical assessment.
Examples include road traffic crashes, falls from height in construction sites, machete injuries in farming communities, or burns from cooking accidents. Each MOI has characteristic risks and expected injury types.
Responders gather information from bystanders, witnesses, or the casualty to establish how the injury occurred. For example, in a school playground incident, understanding whether the casualty fell or was hit by an object shapes the approach to care.
Certain MOIs, like high-speed collisions or crush injuries, warrant urgent transport to a hospital with trauma capabilities, such as Kenyatta National Hospital, while minor injuries may be managed at local health centers.
Determining the nature of injury involves identifying the type and extent of physical damage the casualty has sustained. This assessment shapes immediate interventions and resource allocation.
Injuries may be classified as fractures, lacerations, burns, spinal injuries, or internal bleeding. For example, a burn injury from a kerosene stove explosion requires different management compared to a fractured limb from a fall.
Severity is judged by factors such as bleeding, consciousness level, and respiratory distress. A casualty with profuse bleeding and altered consciousness demands immediate resuscitative efforts.
Some injuries are obvious, such as open wounds, while others like internal bleeding or concussion may not be immediately apparent, requiring careful observation and rapid transport for further evaluation.
Certain injury patterns correlate with specific MOIs. For instance, a pedestrian hit by a vehicle may show head trauma and fractures, while a fall from a tree might cause spinal injuries.
Identifying how many casualties are involved is critical for planning response and requesting additional support. Kenyan community health workers often encounter mass casualty events where this skill is vital.
A single casualty situation may be managed by one responder, but multiple victims require rapid prioritization and coordination with emergency services.
In incidents with many victims, such as a bus accident in a rural county, managing the crowd and ensuring safety for all is a priority to prevent further injuries.
Accurate reporting of victim numbers to dispatch centers or receiving hospitals enables appropriate resource mobilization.
Knowing the number of victims allows for triage, sorting casualties by severity to optimize survival chances, for example, during flooding disasters in Western Kenya.
Assessing available resources includes evaluating personnel, equipment, and transport options to manage the emergency effectively. Resource limitations are common in Kenya’s community health settings, making this step crucial.
Identifying how many trained responders or helpers are on scene influences the complexity of care that can be provided.
Availability of first aid kits, stretchers, oxygen, or splints determines the interventions possible before hospital transfer.
Knowing the nearest ambulance or alternative transport means, such as boda bodas or community vehicles, affects the speed of casualty evacuation.
Access to mobile phones or radios for liaising with hospitals or emergency services supports coordination and timely referrals.

Create a free accountThis chapter provides a comprehensive guide on assessing a casualty, beginning with conducting a scene size-up that includes evaluating scene safety, understanding the mechanism and nature of injury, determining the number of victims, and assessing available resources. It then outlines the process of identifying various emergencies such as severe weather, fire, hazardous materials accidents, chemical, biological and radiological incidents, aircraft crashes, national emergencies like war and terrorism, civil disorder, and active shooter situations. The importance of cordoning the scene to protect both the casualties and responders is emphasized, followed by securing the casualty to prevent further harm. Determining the nature of the incident is critical for appropriate response, as is managing the casualty’s condition through timely and effective interventions. The chapter also covers the conduct of emergency services to stabilize and transport casualties. Finally, it details the identification and proper use of essential tools, equipment, and supplies such as gauze pads, scissors, adhesive tape, tweezers, elastic bandages, CPR face shields, emergency blankets, first aid manuals, and medical gloves to support effective casualty care.
