Development and Testing of a Pediatric Cervical Spine Injury Risk Assessment Tool
An observational study of Cervical Spine Injury, run by Julie Leonard at 18 sites in United States.
Trial summary
Cervical spine injuries (CSI) are serious, but rare events in children. Spinal precautions (rigid cervical collar and immobilization on a longboard) in the prehospital setting may be beneficial for children with CSI, but are poorly studied. Read more about this study

About this study
Cervical spine injuries (CSI) are serious, but rare events in children. Spinal precautions (rigid cervical collar and immobilization on a longboard) in the prehospital setting may be beneficial for children with CSI, but are poorly studied. In contrast, spinal precautions for pediatric trauma patients without CSI are common and may be associated with harm. Spinal precautions result in well-documented adverse physical and physiological sequelae. Of substantial concern is that the mere presence of prehospital spinal precautions may lead to a cascade of events that results in the increased use of inappropriate radiographic testing in the emergency department (ED) to evaluate children for CSI and thus an unnecessary, increased exposure to ionizing radiation and lifetime risk of cancer. Most children who receive spinal precautions and/or are imaged for potential CSI, and particularly those imaged with computed tomography (CT), are exposed to potential harm with no demonstrable benefit. Therefore, there is an urgent need to develop a Pediatric CSI Risk Assessment Tool that can be used in the prehospital and ED settings to reduce the number of children who receive prehospital spinal precautions inappropriately and are imaged unnecessarily while identifying all children who are truly at risk for CSI.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Derivation Cohort | The derivation cohort collected data to derive the clinical decision rule. | |
| Validation Cohort | The validation cohort collected data to validate the clinical decision rule |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cervical Spine Injury
The primary outcome used to derive and validate the prediction rule is the presence of cervical spine injury (CSI) defined as vertebral fracture, ligamentous injury, intraspinal hemorrhage, or spinal cord injury involving the cervical region of the spine (occiput to the 7th cervical vertebra, including ligaments attaching the 7th vertebrae to the 1st thoracic vertebra) on any c-spine imaging modality, including x-ray, skeletal survey, CT scan, and/or MRI.
Measured: CSI diagnosed within 21 days of emergency department presentation

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Cervical spine injuries (CSI) are serious, but rare events in children. Spinal precautions (rigid cervical collar and immobilization on a longboard) in the prehospital setting may be beneficial for children with CSI, but are poorly studied. In contrast, spinal precautions for pediatric trauma patients without CSI are common and may be associated with harm. Spinal precautions result in well-documented adverse physical and physiological sequelae. Of substantial concern is that the mere presence of prehospital spinal precautions may lead to a cascade of events that results in the increased use of inappropriate radiographic testing in the emergency department (ED) to evaluate children for CSI and thus an unnecessary, increased exposure to ionizing radiation and lifetime risk of cancer. Most children who receive spinal precautions and/or are imaged for potential CSI, and particularly those imaged with computed tomography (CT), are exposed to potential harm with no demonstrable benefit. Therefore, there is an urgent need to develop a Pediatric CSI Risk Assessment Tool that can be used in the prehospital and ED settings to reduce the number of children who receive prehospital spinal precautions inappropriately and are imaged unnecessarily while identifying all children who are truly at risk for CSI.

Questions about this trial
What is this clinical trial studying?
An observational study of Cervical Spine Injury, run by Julie Leonard at 18 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 18 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 15 Apr 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cervical Spine Injury (time frame: CSI diagnosed within 21 days of emergency department presentation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05049330, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2026.
