Who Gets Mistriaged? Disparities in Pediatric Behavioral Health ED Triage | A PECARN multicenter analysis

mistriaging of pediatric mental health conditions with ESI
A 14-year-old Hispanic girl presents to the Emergency Department with her mother for suicidal ideation after a conflict at home. The girl is quiet and cooperative. Her mother, who speaks primarily Spanish, is trying to explain the situation. The nurse assigns an ESI level 2, the same score given to nearly every child who walks through the door with a behavioral health complaint. But does that score accurately capture this patient’s needs?

A new multicenter PECARN study published this week in JAMA Network Open takes a close look at triage accuracy for pediatric behavioral health ED visits. The findings: mistriaging errors are common, and they are not equally distributed [1].

Hoffmann et al. analyzed 78,411 ED visits by children aged 5 to 17 with behavioral health chief concerns across 15 PECARN Registry EDs from 2021 to 2023 [1]. They classified each visit as appropriately triaged, overtriaged, or undertriaged using vital signs, Glasgow Coma Scale, pain scores, emergency medication use, resource utilization, and disposition. Of the 74,564 visits with complete data:

  • 57% were overtriaged
  • 34% were appropriately triaged
  • 8.5% were undertriaged

How ESI Handles Behavioral Health

The Emergency Severity Index (ESI) is used in over 90% of US EDs [2]. It sorts patients into 5 acuity levels. Level 1 is for patients needing lifesaving interventions. Level 2 is for high-risk situations, confused patients, or those in severe pain. Levels 3 through 5 are based on anticipated resource needs. In this study, 83.5% of all behavioral health visits were triaged as ESI level 2.

To assess triage accuracy, the authors compared each child’s assigned ESI level against what actually happened during their visit.

Overtriage

Overtriage means a child was assigned a higher acuity score than their clinical course supported. For a child assigned ESI level 2, overtriage was defined as meeting ALL of the following [1]:

  • Stable vital signs within 2 hours of arrival (heart rate and respiratory rate not high risk for age, SpO2 ≥93% or not recorded)
  • Pain score <7 (or not recorded)
  • GCS of 15 (or not recorded)
  • No emergency medications during the visit

In other words, the triage nurse predicted high acuity, but the visit didn’t bear that out.

Undertriage

Undertriage means the opposite: a child was assigned a lower acuity score than their clinical course warranted. For example, a child triaged as ESI level 4 (expected to need 1 resource) who ended up being admitted, needing emergency medications, or using multiple resources. The triage nurse underestimated how sick the child was or how much care they would need.

Undertriage Disproportionately Affects Minority Children and Spanish-Speaking Families

The most concerning equity finding was in undertriage.

After adjusting for clinical and visit characteristics, undertriage was significantly more likely for Hispanic children (AOR 1.46), non-Hispanic Black children (AOR 1.28), and children whose families preferred Spanish (AOR 1.31), all compared to non-Hispanic White and English-speaking patients [1]. The authors point to implicit clinician bias, systemic racism, and underutilization of professional interpreters as likely contributors.

The safety implications are real. Children whose acuity is underestimated may face longer waits, miss time-sensitive interventions, or leave the ED without being seen despite elevated risk.

Overtriage Was Common

More than half of all visits (57%) were overtriaged [1]. These children received a higher acuity triage score than their clinical course supported.

The strongest predictor was age. Children aged 5-9 had over 4-fold higher adjusted odds of overtriage compared to those aged 10-14 (AOR 4.43), possibly because younger children have a limited ability to communicate their symptoms and needs.

To a lesser degree, non-Hispanic Black children also had higher adjusted odds of overtriage compared to non-Hispanic White children (AOR 1.17). The authors cite research on adultification, the tendency to perceive Black youth as older or more threatening than they are, as a potential contributor. This means Black children in this study were more likely to be both undertriaged and overtriaged compared to White children. The errors are not unidirectional. They likely reflect different biases operating at different points in care.

Take Home Points

  1. The ESI has limited ability to differentiate pediatric behavioral health presentations. In this study, 83.5% of behavioral health visits were triaged as ESI level 2.
  2. UNDERTRIAGE was more likely for Hispanic children (AOR 1.46), non-Hispanic Black children (AOR 1.28), and Spanish-speaking families (AOR 1.31), raising concerns about missed acuity in these groups.
  3. OVERTRIAGE occurred in 57% of visits, driven most strongly by younger age (AOR 4.43 for ages 5 to 9) and to a lesser degree by non-Hispanic Black race (AOR 1.17).

Dump the Myths, Not the Milk: Medication and Imaging Considerations for Lactating Patients in the Emergency Department

lactation myths with medications and imaging
The challenges in lactation are often compounded by outdated beliefs held by clinicians.  Most of the medications we administer in the emergency department (ED) do not warrant any interruption in expression or feeding of breastmilk. Most imaging we perform in the ED is safe in the lactating patient and likewise does not need interruption. Let us convince you to trash the phrase, “Pump and Dump” in the ED.

Most medications commonly given in the ED are safe in lactation

Evidence suggests medication transfer through breast milk is frequently overestimated, with actual infant exposure typically minimal for most medications commonly prescribed in emergency settings [1]. The majority of medications administered in the ED are compatible with continued breastfeeding or pumping without interruption [2]. The practice of “pumping and dumping” is harmful to infants and lactating adults given the many benefits of lactation [3, 4]. It can cause irreparable disruptions in supply, increased parental burden and stress, and is not medically indicated except in very rare circumstances (chemotherapeutics for example) [3, 4]. When uncertainty exists regarding medication safety during lactation, clinicians should consult evidence-based resources such as LactMed or the LactRx app [iphone] to provide informed recommendations. A brief summary table is provided below for quick reference on some common medications.

Medication ClassSafe in LactationCautions in Lactation
Analgesia
  • Acetaminophen [5]
  • Ibuprofen [6]
  • Opioids in routine doses: Oxycodone [7], Morphine [8], Hydromorphone [9],  Fentanyl [10]
  • ⚠️ Caution in very high doses or prolonged infusions of opioids
  • Data on oxycodone shows no adverse effects attributed to oxycodone in maternal doses up to 60 mg/day (~90 MME/day) [11], which is well within the range of typical short-term ED prescribing for acute pain [12]
Sedative Hypnotics
  • Propofol [13]
  • Ketamine [14]
  • Midazolam [15]
  • Safe to feed when awake
  • ⚠️ Caution in infusions and higher doses of long-acting benzodiazepines
Paralytics
  • Succinylcholine [16]
  • Rocuronium [17]
  • Safe to feed when no longer paralyzed; likely safe to feed even on infusions
Opioid Use Disorder
  • Buprenorphine [18]
  • Methadone [19]
  • Recommended to continue feeding
Antibiotics
  • Penicillins [20]
  • Cephalosporins [20]
  • Macrolides [20]
  • Metronidazole [21]
  • Doxycycline (≤21 days) [22]
  • ⚠️ Trimethoprim-sulfamethoxazole (Avoid in premature, ill or jaundiced and those with G6PD) [23]
Anti-hypertensives
  • Labetalol [24]
  • Nifedipine [25]
  • Captopril, Enalapril, Benzapril (Lisinopril—less data) [26]
  • HCTZ [27]
  • Furosemide [28]
  • ⚠️ Diuretics may decrease milk supply if dehydrated
  • ❌ ARBs (Losartan) — No safety data and other alternatives are safe [26]
Antidepressants
  • Sertraline [29]
  • Paroxetine [30]
  • Fluoxetine [31]
  • Citalopram [32]
  • Do not stop an effective antidepressant because of lactation. Risk of depression relapse outweighs the small differences in milk transfer.
  • ⚠️ Bupropion (case reports of infant seizures without causal link) [33]
  • ❌ Doxepin (case reports of infant respiratory depression, hypotonia) [34]
Anticonvulsants
  • Carbamazepine [35]
  • Valproic acid [36]
  • Phenytoin [37]
  • Lamotrigine [38]
  • ⚠️ Levetiracetam (levels can be high, monitor for somnolence) [39]
  • ⚠️ Topiramate (case reports of infant somnolence) [40]
  • ❌ Phenobarbital (Avoid due to high infant exposure and sedation risk) [41]

Most Imaging Performed in the ED is Safe in Lactation

Radiation Exposure

Radiation exposure from diagnostic imaging we typically use in the ED (CT, x-ray) is minimal and there is no need to interrupt nursing/pumping [42].

IV contrast

Iodinated and gadolinium contrast agents are safe and do not require interruption of breastfeeding [43]. Read more in the American College of Radiology 2025 ACR Manual on Contrast Media (start at page 94).

In suspected pulmonary embolism (PE), CT pulmonary angiography (CTPA) is preferred over V/Q scan in lactating patients due to contrast safety (no breastfeeding interruption required), speed and availability, and high rates of indeterminate V/Q scans requiring subsequent CTPA [43, 44].

Exception: In the rare circumstance where contrast is contraindicated (such as anaphylaxis) and a radioactive tracer is indicated (V/Q scan with Tc-99m MAA), the radioactivity does warrant separation from both patient contact and milk for a period of time determined by the rate of decay of the specific agent [45]. Keep expressed milk stored appropriately until radioactivity has been able to decay then it’s safe to feed [46].
