The Core Purpose of a Secondary Assessment
A secondary assessment serves as the investigative phase of emergency care, following the immediate life-saving actions of the primary survey. While the primary assessment focuses on identifying and treating immediate threats to the airway, breathing, and circulation (ABC), the secondary assessment is a more detailed and systematic search for other injuries or medical conditions. It is a deliberate, head-to-toe approach to collect a full patient history and perform a thorough physical examination. The goal is to fill in the gaps left by the rapid, initial assessment, ensuring no significant, but less obvious, issues are overlooked. This attention to detail is vital for proper diagnosis, treatment prioritization, and preventing delayed complications.
When and Where a Secondary Assessment Is Conducted
The timing of a secondary assessment is critical. It should only begin once the primary assessment is complete, life-threatening conditions are managed, and the patient is stable. This might occur at the scene of an accident, in the back of an ambulance, or upon arrival at the emergency department. The environment and patient's condition dictate the pace and detail of the assessment. For a stable patient, a complete on-scene assessment is possible. For an unstable patient, the assessment may be accelerated, with remaining details gathered during transport. Reassessment is also an ongoing process, with regular checks of vital signs and interventions to monitor the patient's condition for any deterioration.
Key Components of a Secondary Assessment
The secondary assessment is typically broken down into two main parts: the patient's history and the physical examination. These two components work together to provide a comprehensive picture of the patient's condition.
The Patient History: Using Mnemonics for Clarity
A focused history is obtained using popular mnemonics to ensure all relevant information is collected systematically. The most common is SAMPLE:
- Signs and Symptoms: What the patient feels (symptoms) and what the clinician can see, hear, or feel (signs).
- Allergies: Allergies to medications, foods, and other substances.
- Medications: Current prescription and over-the-counter medications.
- Past Medical History: Any pre-existing medical conditions, illnesses, or hospitalizations.
- Last Oral Intake: The patient's last meal or drink.
- Events Leading to the Illness/Injury: A description of what happened and the events preceding the incident.
For patients with a specific chief complaint, the mnemonic OPQRST can be used to gather more details:
- Onset: When did it start?
- Provocation/Palliation: What makes it better or worse?
- Quality: Can you describe the pain or discomfort?
- Radiation: Does the pain move anywhere else?
- Severity: How bad is it on a scale of 1-10?
- Time: Has the pain changed since it started?
The Physical Examination: A Head-to-Toe Approach
Following the history, a physical exam is performed. For trauma patients, this is often a rapid but thorough head-to-toe assessment. For medical patients, the exam is typically more focused on the specific body system related to their complaint. A common mnemonic for trauma assessment is DCAP-BTLS, which guides the examiner to look for:
- Deformities
- Contusions (bruises)
- Abrasions
- Punctures/Penetrations
- Burns
- Tenderness
- Lacerations
- Swelling
Secondary Assessment in Trauma vs. Medical Scenarios
There are key differences in how a secondary assessment is applied depending on the patient's situation.
| Feature | Trauma Assessment | Medical Assessment |
|---|---|---|
| Focus | Identifying and treating significant injuries and wounds. | Uncovering the nature and cause of the patient's illness. |
| Physical Exam | A comprehensive, systematic head-to-toe examination, often using mnemonics like DCAP-BTLS. | Focused on specific body systems related to the chief complaint. |
| History Gathering | Relies on the SAMPLE history, potentially gathering information from bystanders or family if the patient is unresponsive. | Centers heavily on the patient's narrative, using OPQRST for symptom details and SAMPLE for broader history. |
| Priority Shift | Moves from addressing life threats to finding all occult injuries. | Moves from stabilizing the patient to determining the specific medical diagnosis. |
The Role of Ongoing Reassessment
The assessment process doesn't end with the secondary phase. Ongoing reassessment is a crucial step that involves repeating the primary assessment and vital signs regularly to detect any changes in the patient's condition. This iterative process ensures that a stable patient who suddenly deteriorates receives immediate, appropriate care. It involves re-evaluating the chief complaint and checking on the effectiveness of interventions. This vigilance is a cornerstone of quality emergency care.

Conclusion
In summary, the secondary assessment is a structured, purposeful process that follows the immediate life-saving steps of a primary survey. It gathers a detailed history and performs a systematic physical exam to uncover less apparent, yet significant, medical issues or injuries. Through a methodical approach using mnemonics like SAMPLE and DCAP-BTLS, clinicians can refine their understanding of the patient's condition, leading to more accurate treatment and better outcomes. The process highlights the difference between initial stabilization and a thorough investigation, both essential for comprehensive patient care.
