The word “pediatric” appears in virtually every EMS protocol set in the country. But how often do those protocols actually define it? We wanted to find out.
We analyzed 633 protocols across 95 agencies, covering cardiac arrest, seizures, pain management, tachycardia/bradycardia, RSI/airway, and trauma/TBI. Using AI-assisted extraction, we systematically captured how each protocol defines the pediatric patient: by age, by weight, or not at all.
The short answer: most fall short of a useful definition.
We looked at 95 agency protocol sets. Here’s how they break down:
16% have no pediatric definition anywhere in their published content. We didn’t just check the clinical protocols we extracted. We searched every document in each set for age cutoffs, weight cutoffs, Broselow references, definition language, anything. These agencies use “pediatric” across their protocols without ever telling a paramedic what it means.
34% define pediatric by age only. They’ll say something like “pediatric: under 14 years” or gate a section header by age, but they never state a weight cutoff. That matters, because age doesn’t tell you when to stop doing per-kg math.
33% include a weight-based cutoff in some protocols but not others. They might define pediatric as “under 40 kg” in their seizure protocol but leave it undefined in cardiac arrest. A paramedic working across clinical categories gets a definition sometimes and silence other times.
…and only 17% consistently provided an operational pediatric boundary that included weight-based guardrails.
To be fair, this isn’t as alarming as it might sound at first glance. Most experienced paramedics are not confused about whether an infant, toddler, or young child belongs in a pediatric protocol pathway, and many agencies intentionally leave that boundary to provider discretion rather than hardcoding it into every protocol. In practice, a seasoned medic isn’t going to be confused about whether a 3-year-old is a pediatric patient.
But there’s one scenario where the absence of a written definition really matters: weight-based dosing without a cap.
For medication safety, the question isn’t really “how old is pediatric?” It’s “at what weight do you stop using per-kg dosing?”
Many medications in EMS protocols are dosed differently for kids and adults. The pediatric dose is weight-based (mg/kg), while the adult dose is a fixed amount. Take Amiodarone: a typical pediatric protocol says 5 mg/kg, while the adult dose for VT-with-pulse is a fixed 150 mg. The idea is that smaller patients need a dose scaled to their body, and at some point the patient is big enough to just get the standard adult dose.
The problem is what happens when there’s no max dose and no weight cutoff. A 30 kg child (a typical 9-year-old) at 5 mg/kg gets 150 mg, matching the adult dose exactly. A 50 kg teenager gets 250 mg, well past it. The protocol’s own pediatric formula is now producing doses that exceed what an adult would receive, and there’s nothing telling the paramedic to stop and switch.
We assessed 688 uncapped pediatric weight-based dosages against Acid Remap’s curated dosage reference database. For each one, we asked: at what patient weight does this uncapped dose exceed the safe adult ceiling?
After automated flagging and manual verification against every source protocol document, we found that 31% of agencies have at least one dosage in their protocols considered high risk: no max cap and no pediatric weight cutoff.
The most common culprit was Amiodarone at 5 mg/kg, appearing across 16% of agencies. But some of the more concerning findings were medications with very low crossover weights:
Epinephrine 0.05 mg/kg and Diazepam 0.5 mg/kg (rectal) cross the adult ceiling at just 20 kg, a 5- or 6-year-old.
D25 at 4 mL/kg and Midazolam 0.2 mg/kg for RSI cross at 25 kg.
Tachycardia/bradycardia protocols had the highest at-risk rate at 14%. RSI/airway and trauma/TBI were the lowest; those protocol categories seem to be better about stating caps.
Defibrillation and cardioversion use the same weight-based model (J/kg), and they have the same problem. After manual review, 14% of agencies have at least one truly uncapped electrical therapy entry in a protocol without a pediatric definition: no joule cap, no adult dose reference, nothing.
Most of these land in a reasonable range for a 40 kg child (80-160 J). But in one case, a protocol specifies escalating defibrillation to 10 J/kg. For a 40 kg child, that calculates to 400 J, which exceeds the maximum output of most biphasic defibrillators. The device becomes the safety cap, not the protocol.
None of this is about pointing fingers at specific agencies. Protocol writing is hard. Medical directors are juggling clinical evidence, operational constraints, and the reality that their protocols get used by providers with wildly different experience levels, often at 3 AM.
But the pattern is clear: EMS protocols routinely use “pediatric” as if everyone agrees on what it means, and they routinely provide weight-based dosing without guardrails for the upper end. These aren’t theoretical risks. They’re math problems that a heavy kid and a stressful call can turn into real ones.
The good news? These are fixable gaps. A weight-based cutoff and a max dose cap are each a single line of text. The hard part is knowing where they’re missing, and that’s exactly what technology-assisted protocol review can do at scale.
Acid Remap built the Paramedic Protocol Provider (PPP) to solve exactly this kind of problem. Our medication calculator isn’t a generic drug reference. It’s built directly from your agency’s own protocol documents. When your medical director writes “Amiodarone 5 mg/kg, max 150 mg,” that’s exactly what your providers see in the field.
Our AI-powered extraction workflow reads your protocol PDFs, pulls out every medication, dose, route, and indication, and flags inconsistencies before they ever reach a provider’s screen. Missing max caps, undefined pediatric cutoffs, dosages that don’t match across documents: these are the kinds of issues that hide in plain sight for years until someone catches them the hard way. We catch them during onboarding.
Every extracted dosage is verified against a curated reference database and reviewed by our team before it goes live. The result is a calculator that reflects what your medical director actually intended, not what a generic reference assumes.
If your agency’s protocols haven’t been through this kind of review, they probably should be. Contact us to learn more.
The study analyzed 94 EMS protocol sets across six clinical categories (cardiac arrest, seizure, pain management, tachycardia/bradycardia, RSI/airway, trauma/TBI) using an LLM to capture structured data — pediatric definitions, dosage entries, and cap status — from each protocol. For the 47 sets with no in-protocol definition, a regex-based secondary search was run across all content files. The 351 uncapped weight-based dosage entries were then matched against a curated Dosage Reference Range (DRR) database using FAISS embedding search for medication normalization and an LLM subagent to select the relevant DRR and calculate the crossover weight where the uncapped dose would exceed the adult ceiling. Electrical therapy entries were reviewed separately against the same pediatric-definition and cap criteria.
This research was conducted by Acid Remap using protocol data from the Paramedic Protocol Provider (PPP) platform.
