A Study Evaluating the Use of ResAppDx v2.0 as an Aid to Diagnose Respiratory Disease in Paediatric Patients in an Emergency Department
United Kingdom75 participantsStarted 2024-01-01
Plain-language summary
Aim of study is to demonstrate that the ResAppDx v2.0 algorithms provide an accurate diagnosis of paediatric respiratory disease in the study's clinical setting compared to a Clinical Adjudication Committee's (CAC) diagnosis; and to establish a baseline for the resource use and cost of current care pathways for paediatric respiratory disease diagnosis in an emergency department. Eligible subjects/parents will be assented/consented, enrolled and their subject reported signs/symptoms of respiratory disease will be recorded in the study electronic case report form (eCRF).The enrolled subject's cough sounds will be captured (5 cough sounds are required) using the ResAppDx v2.0 Investigational Device (ID) software installed on a study smartphone; cough sounds may be voluntary and/or involuntary/spontaneous. As this is an observational study the treating team will be blinded to the ResAppDx v2.0diagnoses. Additional medical information will be collected from the treating team, from the subject/parent and from the subject's medical record. No follow-up/subsequent visits with the subject will be required by the study. As an efficacy comparator, a CAC will determine the final clinical diagnosis for each enrolled subject using the disease case definitions, eCRF data, the subject's medical record and cough sound recordings.Information on time and scope of tests and consults ordered by the treating team will be recorded to set a baseline for resource use and cost and time of current standard of care treatment/assessment procedures. This data will allow future health economics analyses to be performed.The blinded ResAppDx v2.0diagnoses will be unblinded after database lock and sensitivity and specificity will be calculated for the ResAppDx v2.0diagnoses compared to agreement with the CAC's final clinical diagnoses for this cohort.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Presenting to the study site with current signs or symptoms of rhinorrhea, cough, wheeze, stridor, increased work of breathing, cyanosis, additional auscultatory noises (crepitations), or low oximetry levels.
. Onset of symptoms must have occurred within the past 14 days.
Exclusion criteria
. Parent or legal guardian is unwilling or unable to sign the study informed consent form.
. A child who, in the opinion of the investigator, is able to provide assent based on their age, maturity or psychological state is unwilling or unable to sign the study assent form.
. Patient requires mechanical ventilatory support (including invasive, CPAP, or BiPAP) or high flow nasal cannula
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
