Summary

This study tested a mobile app called Pain Buddy in 206 children aged 8-18 receiving outpatient chemotherapy for cancer. The app lets kids and parents record daily pain, symptoms, and quality of life using a personalized avatar. The goal is to help doctors and nurses monitor symptoms in real time and provide better pain management, ultimately improving children's well-being at home.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Pain Buddy mobile application
What this could lead to
If successful, this could lead to a simple, effective way for doctors and parents to monitor and manage children's cancer pain and symptoms remotely, improving their quality of life.
What could go wrong
This is a feasibility study, not a treatment trial. The app may not reduce pain or symptoms on its own, and results may not apply to all children or settings.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

407 people

The number who actually took part.

Started

Aug 2019

Finished

Jun 2025

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

8 to 18 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Between the ages of 8-18 years * Currently undergoing outpatient treatment for cancer * Patients who are able to speak, read, and write in English. Parents who are able to speak, read, and write in English or Spanish * Have home internet access to use Pain Buddy (the internet will be used to securely send the pain information to the research team). Exclusion Criteria: * Cognitive impairment, such as a developmental delay or mental retardation that would prevent children from being able to use the Pain Buddy program. * Children diagnosed with acute myelogenous leukemia (AML) or acute promyelocytic leukemia (APL) as the treatment protocols for these children are largely inpatient, precluding use of the intervention.
