1.3 Advanced Pediatric Triage, Acuity Stratification & Rapid Response Systems
Key Takeaways
Use appearance, work of breathing and circulation to skin to form a first impression. Confirm findings in the primary survey while treating immediate threats.
In ESI v5, decide whether the child needs immediate lifesaving care or has a high-risk presentation before counting predicted resources.
Follow the local early-warning and escalation pathway. Urgent clinical deterioration warrants action even if a score is incomplete or low.
Communicate changes and requests clearly, confirm who will carry out each action, and reassess the child after interventions.
Pediatric Triage, Acuity and Rapid Response
Quick Answer: Use the Pediatric Assessment Triangle to recognize immediate threats and begin the primary survey and stabilization. In the ED, the Emergency Severity Index (ESI) prioritizes lifesaving intervention and high-risk presentation before predicted resources. On the ward, assess clinical trends and use the local early-warning and escalation system. Call for urgent help for new life threats and communicate the patient's current condition and requested action.
Form the first impression and verify it at the bedside
The Pediatric Assessment Triangle (PAT) uses a rapid visual and auditory assessment of appearance, work of breathing and circulation to skin. It can start as you approach the child. Do not delay treatment to complete the triangle. Compare behavior with developmental baseline and ask caregivers what has changed.
- Appearance (TICLS): Observe tone, interactiveness, consolability, look or gaze, and speech or cry. Limp tone, poor interaction or a weak cry can reflect serious compromise. Consider developmental differences, sedating medications, fatigue and illness.
- Work of breathing: Look for retractions, nasal flaring, head bobbing, abnormal positioning and poor chest movement. Listen for stridor, grunting or wheeze. A tiring child may become quieter and make less effort as ventilation worsens.
- Circulation to skin: Observe pallor, mottling or cyanosis and compare with baseline skin appearance. Check the lips and tongue for central cyanosis. Examine pulses, refill, blood pressure and mental status during the primary survey. Skin color changes have more than one possible cause.
| Appearance | Work of breathing | Circulation to skin | First impression to investigate |
|---|---|---|---|
| Usual | Usual | Usual | No immediate abnormality on the triangle. Continue triage and evaluate high-risk history. |
| Usual | Abnormal | Usual | Respiratory distress. Check air entry and oxygenation. |
| Abnormal | Abnormal | Usual | Respiratory failure pattern. Assess ventilation and support it promptly as needed. |
| Usual or abnormal | Usual | Abnormal | Shock pattern. Abnormal appearance suggests greater compromise. Check perfusion and blood pressure and assess cause before selecting fluids or other treatment. |
| Abnormal | Usual | Usual | CNS or metabolic pattern. Check glucose and consider seizure, toxic exposure and other causes. |
| Abnormal | Abnormal | Abnormal | Cardiopulmonary failure pattern. Activate resuscitation and assess need for ventilation or CPR immediately. |
The pattern prioritizes actions. It cannot confirm blood pressure, oxygenation or the cause of shock. In an infant with pallor, weak pulses and lethargy, assess for hypovolemia, sepsis and cardiac causes, and check glucose while supporting airway and perfusion. Normal blood pressure does not exclude shock. Base fluids on the likely cause and reassess the response and signs of overload. PAT triage study · 2025 AHA/AAP pediatric advanced life support
Assign ED acuity with Emergency Severity Index version 5
Start with the need for immediate lifesaving treatment. Then assess high-risk presentation, acute change in alertness or severe pain or distress. Predict resources only after those decisions. ESI is a triage tool and the assignment can change with the patient's condition.
| Level | ESI decision |
|---|---|
| 1 | Immediate lifesaving intervention is needed, such as bag-mask ventilation for ineffective breathing or emergency circulatory support for profound shock. |
| 2 | High-risk presentation, acute confusion, lethargy or disorientation, or severe pain or distress that warrants high acuity. A child with stridor, adequate ventilation and concern for rapid airway deterioration may fit here. Immediate airway rescue would make the child level 1. |
| 3 | Two or more different resource types expected, after evaluating high-risk vital signs and reconsidering the acuity. |
| 4 | One resource expected. An otherwise low-risk child needing only a radiograph or simple laceration repair may fit here. |
| 5 | No counted resources expected. History and examination, oral medication or a prescription refill are examples of care that ESI does not count. |
ENA v5 counts blood or urine laboratory testing, imaging, IV hydration, parenteral or nebulized medications, specialty consultation and specified procedures. Point-of-care testing, a saline lock alone and simple wound dressings are among items it does not count. For example, a low-risk child whose planned care is a point-of-care test and oral medication still has no counted resources under v5. At the high-risk vital sign step, consider whether findings outside age-based parameters warrant higher acuity. The v5 table gives a heart rate above 140/min, respiratory rate above 40/min or SpO₂ below 92% as high-risk values in the 1–3-year band. These values prompt reassessment in clinical context, including baseline in medically complex children. Do not wait for the resource step when a child already needs lifesaving care.
Apply the v5 pediatric fever considerations and the local young-infant pathway. For example, a 20-day-old with a measured temperature of 38.2°C warrants at least ESI 2 even if initially well appearing. Obtain and document age-appropriate vital signs, mental status, pain and weight in kilograms as soon as feasible. Reassess a waiting child at the locally specified interval and sooner with a concerning change, after an intervention or when caregivers raise a new concern.

Recognize and escalate inpatient deterioration
Pediatric early warning systems combine repeated observations with a pathway for assessment and escalation. Tools differ. The seven-item Bedside PEWS developed by Parshuram ranges from 0 to 26. Use the tool, baseline exceptions, repeat intervals and response criteria adopted by the unit. A new oxygen requirement, altered consciousness, poor perfusion or a rapid change from baseline can demand immediate action regardless of the aggregate score. The EPOCH randomized trial found no significant reduction in all-cause hospital mortality after implementing BedsidePEWS. A score supports bedside detection and communication.
- Recognize: Verify unexpected measurements while examining the patient. Use nurse and caregiver concerns and clinical trajectory alongside recorded values. Tell families how to escalate concerns using the hospital's available pathway.
- Respond: Call the rapid response or medical emergency team for serious deterioration before arrest. Start bedside stabilization as help arrives. Activate the resuscitation team and begin CPR when arrest criteria are met. Follow local criteria for intensive care review and transfer.
- Reassess: Evaluate response after each intervention and assign someone to monitor, communicate changes and arrange the next level of care.

Communicate urgency and confirm completion
Use SBAR to state the situation, relevant background, current assessment and recommendation. For example: “This is the surgical ward. A child after laparotomy is newly obtunded and has increasing oxygen needs. We need the rapid response team now. We are assessing ventilation and perfusion at the bedside.” Assign a named person to each task. With a check-back, the receiver repeats the instruction, the sender confirms or corrects it, and the receiver reports completion and findings. Continue treatment during the handoff.

A 9-month-old with vomiting and poor feeding has a weak cry, limp tone and poor visual tracking. Breathing is unlabored, and the skin is pale and mottled. Which first impression and next assessment best fit the Pediatric Assessment Triangle?
Respiratory distress. Recheck retractions after giving a bronchodilator.
Isolated CNS disturbance. Defer circulation assessment until neuroimaging is complete.
Shock with concerning appearance. Assess pulses, refill, blood pressure and likely cause while beginning stabilization.
Adequate perfusion. Return the infant to the waiting area because breathing is unlabored.
An 18-month-old with retractions and an SpO₂ of 88% on room air becomes difficult to arouse. Respiratory effort is now irregular and chest movement is poor. The child needs immediate bag-mask ventilation. Which ESI v5 level applies?
Level 4 because a single respiratory treatment is anticipated.
Level 3 because the child will likely need multiple resources.
Level 2 because oxygen saturation and alertness make this high risk.
Level 1 because immediate assisted ventilation is required.
A 4-year-old on the surgical ward after laparotomy has a rapidly rising local early-warning score. The child is newly obtunded, tachycardic and increasingly hypoxemic despite oxygen, with a palpable pulse. What should the team do now?
Activate rapid response, assess and support airway, ventilation and circulation at the bedside, and coordinate higher-level care.
Wait for a blood gas and a repeat early-warning score before calling for help.
Treat presumed surgical pain with an opioid bolus and reassess after it takes effect.
Increase the frequency of vital signs and defer bedside review to the next scheduled round.
