Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 21 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Study population: Subjects will include all patients admitted to the five participating pediatric stem cell transplant sites for the purpose of HSCT during the study period. Enrollment goal is 1000 subjects overall, and 240 subjects for neurocognitive testing. Subjects will be seriously ill. Every patient admitted for HSCT will be eligible for inclusion, unless they are >21 years old. Subjects will be enrolled regardless of gender, race, or ethnicity. No subgroups will be excluded, as delirium likely affects children of all ages and developmental trajectories, with no predilection based on gender, race, or ethnicity.

Who may be able to join

  • Age 0-21 years old
  • Admitted for purpose of stem cell transplant

Who cannot join

  • Age >21 years old
  • Admitted for reason other than stem cell transplant (example: late post-transplant complications).

About this study

Official title: Delirium in Children Undergoing Stem Cell Transplantation: Epidemiology and Outcomes

Children undergoing stem cell transplants are at risk for delirium, a temporary change in thinking and behavior. This study will define delirium rates, risk factors, and outcomes. Our eventual goal is to reduce delirium in this population.

Read the detailed description

Delirium -- defined as an acute change in awareness and cognition that occurs in the setting of an underlying illness -- is a common complication of hematopoietic stem cell transplantation (HSCT) in adults, with associated morbidity and mortality. This has never been studied in children, where risk factors may vary substantially from adults. The objectives of this study are: to define the epidemiology of delirium, and measure its effect on outcomes.

This prospective longitudinal cohort study will prospectively establish the incidence of delirium in 1000 children in the peri-transplant period, and identify modifiable risk factors that predispose to delirium development. This study will also define the effect of delirium on important clinical outcomes, including neurocognitive function. This study will be executed by a research consortium of five leading pediatric oncologic transplant centers in North America, in collaboration with the leading pediatric delirium research group in the United States.

This innovative proposal will leverage the combined experience of the pediatric delirium and HSCT teams to expand urgently needed delirium research into a unique and unstudied population. By reducing delirium rates, outcomes after pediatric HSCT can be optimized.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Delirium incidence

    Number of patients who develop delirium during the course of their transplant hospitalization

    Measured: 1-50 days

Secondary outcomes (4)
  1. Hospital length of stay

    Length of transplant hospitalization will be measured in days.

    Measured: 1-365 days

  2. Mortality rate

    Count will include number of patients with either in-hospital or post-discharge mortality.

    Measured: 1-5 years

  3. Readmission rate

    Count will include number of patients who are readmitted to the hospital within 30-days of discharge.

    Measured: 1-365 days

  4. Change in neurocognitive functioning as measured by the NIH Toolbox Cognition Battery

    Neurocognitive functioning will be measured by the NIH Toolbox Cognition Battery, and reported as a total composite score ranging from 50-150. An average score, adjusted for age, is 100. A score lower than 100 indicates lower cognitive functioning than average; a score higher than 100 indicates higher cognitive functioning than average.

    Measured: pre-transplant, 3 months after transplant, 12 months after transplant

Individual data sharing
Yes: De-identified individual participant data will be shared via NIH-approved repositories within 12 months after publication of primary results. The sharing of unpublished information may be subject to confidentiality issues and will need to be discussed with the appropriate institutions before any request is granted. Access will be granted to qualified researchers with a methodologically sound proposal and appropriate agreements, for academic research, meta-analyses, and other approved studies.

Questions about this trial

What is this clinical trial studying?

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 2 inclusion and 2 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: under way, not looking for participants, as of the sponsor's last update on 23 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Canada. 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?

This study is still under way. Results are not available in the source record yet.

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?

Delirium incidence (time frame: 1-50 days). 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 NCT04937400, which also lists 1 linked publication.

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 23 Oct 2026.
