Scene Assessment for AFA & EMR: A Step-by-Step Guide

Discover how first responders assess scenes in seconds using real tools like HEMPPA, PWCATS, and SCORTS. We teach it in our EMR course — with real-world scenarios to make it stick.

In emergency medical care, scene assessment is your first critical move. It ensures your safety, guides your approach to the patient, and sets the foundation for triage, treatment, and transport. Whether you’re first on the scene or part of a larger response team, a systematic assessment process helps you stay focused and effective.

🚨 Step 1: Scene Overview – HEMPPA

The acronym HEMPPA helps responders quickly assess for overall scene safety and initial priorities:

H – Hazards

  • Look for anything that could harm you, the patient, or bystanders.

  • Examples: traffic, fire, electricity, gas, violence, sharp objects.

  • Why it matters: A dead rescuer helps no one. Always protect yourself first.

E – Environment

  • Assess conditions like weather, lighting, terrain, and location access.

  • Slippery roads, tight spaces, or poor visibility can impact patient care and evacuation.

M – Mechanism of Injury (MOI) / Nature of Illness (NOI)

  • MOI: What caused the injury? (e.g., fall from height, motor vehicle crash)

  • NOI: For medical calls, what’s wrong? (e.g., chest pain, shortness of breath)

P – Patients (Number)

  • Are there multiple patients?

  • Call for more resources if needed (e.g., MVC with multiple occupants).

P – PPE (Personal Protective Equipment)

  • Gloves, eye protection, masks — wear what’s appropriate to protect from bodily fluids or contaminants.

A – Additional Resources

  • Fire, police, ALS units, specialized rescue — ask early.

  • Helps control the scene, provide support, or manage large-scale incidents.

🧠 Step 2: What Else Should You Ask or Observe?

Here are key scene-based questions that build context before you even touch the patient:

  • Position of the patient: Supine, seated, slumped, or ejected from vehicle?

  • Witness reports: What did bystanders or family see? Events leading up to the incident?

  • Chief complaint: What is bothering the patient most right now?

  • Age & gender: Helps form medical differentials quickly.

  • Is the patient tracking/responding? (Eye contact, awareness)

  • Skin colour and condition: Pale, cyanotic, flushed? Cool, clammy, hot? Clues for perfusion.

🔤 PWCATS: For Immediate Patient Impressions

PWCATS helps EMRs gather critical info during the primary assessment.

P – Position

  • Are they standing, lying, slumped, or fetal?

  • Can indicate level of distress or unconsciousness.

W – Witnesses

  • Ask what happened, timing, onset of symptoms, seizure activity, etc.

  • Helps reconstruct events and guide priorities.

C – Chief Complaint

  • What’s their main issue? Chest pain, difficulty breathing, pain scale?

  • Directs your initial focus and treatment.

A – Age

  • Children and elderly present differently.

  • Age affects vital signs, resilience, and urgency of care.

T – Tracking (eye contact/alertness)

  • Are they focused? Following your movements?

  • Quick check of neurologic status or altered mental state.

S – Skin (colour, condition, temperature)

  • Pale, cool, clammy = shock.

  • Flushed, hot = fever or heat stroke.

  • Cyanosis (blue lips/nails) = hypoxia.

⚠️ SCORTS: Scene-Specific Red Flags

Use SCORTS to identify serious, time-sensitive conditions or complicating factors:

S – Stridor / SOB (Shortness of Breath)

  • Upper airway obstruction or respiratory distress?

  • High priority for airway intervention or oxygenation.

C – C-Spine

  • Suspect spinal injury if trauma involved (falls, MVCs).

  • Apply manual stabilization early if indicated.

O – Obvious Bleeding

  • Life-threatening external bleeds need immediate control — pressure, tourniquet, or dressing.

R – Rural / Remote

  • Consider access to definitive care, transport time, or need for air medevac.

  • Distance may increase urgency for certain interventions.

T – Time from ER

  • How far are you from advanced care?

  • May influence treatment decisions, especially in critical cases.

S – Stable / Unstable

  • Is the patient deteriorating? ABCs intact?

  • Helps you determine the transport priority and whether to initiate rapid extrication.

🧭 Scene Assessment in Action: Example Workflow

  1. Pull up, pause, and scan: Use HEMPPA.

  2. Approach safely with PPE on.

  3. Identify number of patients, call for help if needed.

  4. Walk up, observe PWCATS.

  5. Start ABC assessment and initiate any urgent interventions.

  6. Consider SCORTS: look for red flags or complicating factors.

  7. Report findings and updates using structured handover (e.g., ISBAR or CHART).

How to Manage Delirium in Geriatric Patients: Essential Skills for EMRs and Firefighters

Delirium is an acute medical condition that often affects geriatric patients, causing confusion, disorganized thinking, and altered levels of awareness. As an EMR or firefighter, it's crucial to identify delirium early and manage it effectively. This guide explains how to assess, treat, and respond to elderly patients showing signs of delirium, ensuring optimal care in critical situations.

Delirium in the Geriatric Patient: How EMRs and Firefighters Can Identify and Respond

Delirium is a serious medical condition, particularly in the elderly, and as an EMR or firefighter, it’s crucial to recognize the signs early and act swiftly. Unlike dementia, which progresses slowly over time, delirium can develop acutely and rapidly change the patient’s mental status, presenting significant challenges for first responders. In geriatric patients, delirium is a medical emergency that often requires urgent intervention.

This blog will guide you on how to recognize delirium, understand its underlying causes, and effectively manage geriatric patients experiencing it.

What is Delirium?

Delirium is defined as an acute and fluctuating onset of inattention, disorganized thinking, and/or altered levels of awareness. It differs from dementia in that it is temporary and occurs suddenly, often in response to an underlying medical condition or environmental trigger.

The symptoms of delirium typically appear suddenly and may fluctuate throughout the day. Common signs include:

  • Inattention: Difficulty maintaining focus, distracted, or unable to follow a conversation.

  • Disorganized Thinking: Incoherent or illogical speech, trouble forming coherent thoughts.

  • Altered Awareness: The patient may be either overly drowsy (hypoactive) or agitated (hyperactive). In many elderly patients, hypoactive delirium is most common and can often go undetected in emergency situations.

Why is Delirium Common in Geriatric Patients?

The elderly population is particularly susceptible to delirium for several reasons, including:

  • Age-Related Physical Changes: Aging can cause changes in the brain that make older adults more vulnerable to confusion and mental disturbances.

  • Underlying Medical Conditions: Chronic health issues like heart disease, diabetes, or kidney failure may predispose the elderly to developing delirium.

  • Medications: Certain medications, especially in combination, can trigger delirium in older patients. Common culprits include sedatives, narcotics, and anticholinergics.

  • Infections: Conditions like urinary tract infections (UTIs) and pneumonia are known triggers of delirium in the elderly.

  • Environmental Factors: Hospitalizations, changes in routine, or unfamiliar environments (e.g., new settings after an injury) can exacerbate confusion and lead to delirium.

Recognizing Delirium in the Elderly

As an EMR or firefighter, recognizing delirium is a crucial skill that can improve patient outcomes. Delirium may not be as obvious as other acute conditions, especially since the elderly are often at risk of hypoactive delirium, which can manifest as lethargy or withdrawal rather than agitation.

Key Symptoms to Look For:

  • Inability to focus: The patient may appear "spacey," unable to follow a conversation, or may forget what they were just talking about.

  • Confusion: They may be disoriented, unable to recall where they are, or confused about the time and date.

  • Fluctuating alertness: The patient's level of awareness may change rapidly, ranging from excessive sleepiness to periods of hyperactivity or aggression.

  • Hallucinations or Delusions: While less common, some patients may see or hear things that aren’t there, or they may have false beliefs (e.g., believing they’re in a completely different location).

Hypoactive Delirium: A Hidden Danger

It’s important to note that 70% of delirium cases in elderly patients are hypoactive, meaning the patient may seem unusually drowsy, withdrawn, or lethargic. This subtle form can often go undiagnosed in the emergency department (ED) or in the field because the patient may not exhibit the typical signs of agitation. As a first responder, you must be aware that any older adult exhibiting lethargy or confusion after a recent trauma or medical event could be suffering from delirium.

Common Causes of Delirium in the Geriatric Patient

Several medical conditions or factors may trigger delirium in older adults, making them more vulnerable to changes in their cognitive state. As an EMR or firefighter, understanding these causes can help you quickly identify potential underlying issues:

  1. Infections: UTIs, pneumonia, or sepsis can quickly lead to delirium in elderly patients.

  2. Dehydration and Malnutrition: Inadequate fluid or nutrition intake can significantly affect brain function.

  3. Medications: Polypharmacy, or the use of multiple medications, is common in elderly patients and can interact to cause confusion or delirium. Pay special attention to narcotics, sedatives, and antihistamines.

  4. Pain or Injury: Trauma, especially head injuries, can trigger delirium, as can untreated pain.

  5. Hospitalization: Elderly patients who are hospitalized for an acute illness or injury may experience delirium due to the stress of hospitalization, changes in routine, and medication side effects.

  6. Alcohol Withdrawal: If the elderly patient has a history of alcohol use and suddenly stops drinking, delirium may occur.

How EMRs and Firefighters Can Respond to Delirium in the Elderly

When faced with a patient exhibiting signs of delirium, quick and effective action is critical. Below are steps for managing these patients:

1. Initial Assessment

  • Ensure Safety: The first priority is ensuring the safety of the patient. Patients experiencing delirium may be disoriented or agitated, so they could put themselves or others at risk. Ensure a safe environment and avoid sudden movements that might escalate confusion.

  • Take a Comprehensive History: If possible, gather a thorough history from caregivers, family, or bystanders. Ask about the patient’s recent health changes, medications, and any prior cognitive issues.

  • Rule Out Life-Threatening Causes: Delirium can be a sign of a serious condition such as an infection, stroke, or head injury. Check vital signs and assess for any signs of a critical underlying cause (e.g., hypotension, fever, abnormal heart rate, etc.).

2. Address Underlying Causes

  • If the delirium is due to a known cause (e.g., an infection), it is critical to treat the underlying issue as soon as possible.

  • Consider the possibility of hypoxia, hypoglycemia, or medication-related causes, which can often be quickly addressed in the field.

  • If the patient is in pain or has a known medical condition that could be contributing to confusion (like dehydration), take steps to manage it immediately.

3. Monitor the Patient

  • If the patient is not yet stable, keep a close watch on their mental status. Delirium can fluctuate, so continuous assessment is key.

  • Stay calm and provide reassurance to the patient. If they are agitated, offer clear explanations and avoid confrontational responses.

  • Transport to the hospital promptly, ensuring that the medical team is aware of the patient’s delirium so they can investigate and treat the underlying cause quickly.

4. Engage Family or Caregivers

  • When possible, engage family members or caregivers to help assess the patient's baseline mental status and to provide relevant medical history, including recent changes or new medications.

Conclusion

Delirium in geriatric patients is a common, often undiagnosed condition that presents a unique challenge for EMRs and firefighters. Because it can rapidly change from one moment to the next, it's essential to recognize the signs of delirium early and manage the underlying causes. Prompt action, effective communication with medical teams, and ensuring patient safety are key components in improving patient outcomes.

As a first responder, your ability to identify delirium and intervene early can mean the difference between a successful recovery and long-term complications. By staying vigilant and informed, you can ensure that older patients receive the timely, life-saving care they need.

On the Frontline: Mastering Scene Assessment for AFA with Calgary & Edmonton Fire Departments

During an emergency, AFAs are trained to conduct thorough scene assessments to gather crucial information that informs the appropriate course of action. This includes assessing the safety of the scene, identifying hazards, evaluating the mechanism of injury or nature of illness, and determining the number of patients and their condition. By working closely with Calgary & Edmonton Fire Departments, we (EMS) can collaborate on scene management strategies, coordinate resources, and prioritize patient care based on the severity of injuries or illnesses.

Mastering AFA Scene Assessment with Calgary & Edmonton Fire Departments.

The safety of the AFA and the team is the top priority. Before entering the scene, the AFA should carefully assess for potential hazards, such as traffic, fire, hazardous materials, or violence. This may involve observing the scene from a safe distance to determine if it's safe to approach. If there are any immediate dangers, the AFA should take appropriate precautions, such as wearing PPE, using caution signs, and calling for assistance from, Police, EMS, Calgary Fire or Edmonton Fire departments, if needed.

as Advanced first aiders, Calgary FIRE & Edmonton Fire Departments always perform scene assessments during an emergency response.

  1. Scene Size-Up: The AFA should assess the overall size and nature of the scene. This includes identifying the location, type of setting (e.g., residential area, workplace, public location), and any specific details that may impact the response, such as the presence of bystanders, vehicles, or potential sources of danger. This information helps the AFA get a general understanding of the situation and plan their approach accordingly, while coordinating with the Calgary or Edmonton fire department if necessary.

  2. Mechanism of Injury or Nature of Illness: The AFA should observe and gather information about the mechanism of injury or nature of illness. This includes identifying how the injury or illness occurred, such as a motor vehicle accident, a fall, a medical emergency, or a traumatic injury. Understanding the mechanism of injury or nature of illness can help the AFA anticipate potential injuries or illnesses and determine the appropriate course of action for care, while keeping the Calgary or Edmonton fire department informed as needed.

  3. Number of Patients: The AFA should assess the number of patients involved in the incident. This may include identifying if there are multiple patients or just one. This information helps the AFA determine the need for additional resources and prioritize care, while coordinating with the Calgary or Edmonton fire department to ensure adequate care for all patients.

  4. Initial Impressions: The AFA should formulate an initial impression of the patients' condition(s) based on their observations from a distance. This includes looking for obvious signs of life-threatening conditions, such as unresponsiveness, difficulty breathing, severe bleeding, or obvious deformities. This initial impression can help the AFA prioritize care and initiate appropriate interventions, while keeping the Calgary or Edmonton fire department updated on the patients' status.

  5. Additional Resources: The AFA should determine if additional resources are needed, such as additional EMS units, the Calgary or Edmonton fire department, or law enforcement. This may involve communicating with dispatch or calling for assistance from the Calgary or Edmonton fire department as necessary. The AFA should ensure that appropriate resources are enroute to the scene to provide timely and effective care.

  6. Personal Protective Equipment (PPE): The AFA and the team should ensure that they are wearing appropriate PPE for the situation. This includes gloves, mask, goggles, and other protective gear as needed, to prevent exposure to potential hazards or communicable diseases. Wearing PPE is crucial to protect the AFA and the team from any potential risks during the response, while coordinating with the Calgary or Edmonton fire department for additional support if required.

  7. Consideration of C-Spine: If there is a possibility of a spinal injury, the AFA should consider and maintain cervical spine precautions until further assessment can be performed. This may involve stabilizing the head and neck and avoiding any unnecessary movement that could worsen a potential spinal injury, while coordinating with the Calgary or Edmonton fire department for specialized assistance if needed.

  8. Approach to Patients: The AFA should approach patients with care, assess their level of consciousness, and initiate appropriate care based on their assessment findings and protocols. This may include checking for responsiveness, assessing airway, breathing, circulation, and any obvious injuries. The AFA should provide care based on their training and protocols, while coordinating with the Calgary or Edmonton fire department for any additional support or specialized care that may be required.

  9. Ongoing Assessment: The AFA should continuously reassess patients' conditions and monitor their vital signs, symptoms, and response to interventions. This includes checking for any changes in the patients' condition, identifying any new injuries or symptoms, and adjusting the care plan as needed. The AFA should communicate any changes or updates to the Calgary or Edmonton fire department and coordinate any necessary interventions or transport arrangements.

  10. Documentation: The AFA should document their findings, assessments, interventions, and any communication with the Calgary or Edmonton fire department. This includes recording vital signs, patient information, and any other relevant details in the appropriate format or system. Accurate and thorough documentation is essential for continuity of care, communication with other healthcare providers, and potential legal purposes.

  11. Handover to Higher Level of Care: If the patients require a higher level of care beyond the scope of the AFA's training or capabilities, the AFA should initiate handover to the Calgary or Edmonton fire department or other appropriate healthcare providers. This may involve providing a concise and accurate report of the patients' condition, care provided, and any pertinent details to ensure a smooth transition of care.

  12. Scene Management: The AFA should actively manage the scene throughout the response, ensuring the safety of all individuals involved and coordinating with the Calgary or Edmonton fire department and other responding agencies as needed. This may include establishing a safe zone, controlling traffic, managing bystanders, and coordinating resources and logistics to ensure an efficient and effective response.

  13. Follow-up: After the response, the AFA should debrief with the team, review the incident, and identify any areas for improvement. The AFA should also complete any necessary paperwork, reports, or documentation related to the incident, and follow any relevant protocols or procedures for reporting and follow-up. This may also include communicating with the Calgary or Edmonton fire department for any necessary follow-up or information sharing.

In conclusion, mastering scene assessment is a critical skill for Advanced First Aid (AFA) responders, and depending on your location, collaboration with Calgary Fire & Edmonton Fire Departments is crucial for efficient and effective emergency response. Through meticulous scene assessments, patient assessments, and accurate documentation, AFAs can work for fire departments and ensure scene safety and provide timely and appropriate medical care to those in need.

The partnership between AFAs and fire departments is vital in delivering excellence in emergency response on the frontline in Alberta. By continuously honing their skills and working together, AFAs and fire departments strive to provide the highest level of care to patients in emergency situations. It's important to remember that the roles and responsibilities of an AFA may vary depending on local regulations, protocols, and training. It's essential to always work within your scope of practice and seek appropriate guidance from your Fire department or other healthcare providers as needed.
