Family procedures and optional substudies
Make the distinction clear
All participating families receive a WheezeScan and swab kit. Blood sampling and lung-function measurements are separate, site-dependent substudies.
Swabs and WheezeScan
Train every family to use WheezeScan and to collect nasal and mouth samples when their baby develops a chest infection. Parents send the samples directly to Cardiff using the supplied materials and instructions.
Lung-function substudy
Where offered, follow the dedicated consent, measurement, calibration, acceptability and data-transfer guidance.
Blood substudy
Where offered, use the current consent, sampling video and guidance for timing, volumes, processing and shipment.
Safety first
Clinical care always takes priority.
Assess and treat an unwell baby according to usual clinical practice. Then determine whether expedited safety reporting, treatment interruption, protocol-deviation reporting or unblinding is required.
Supporting families
Consistency without pressure
Explain uncertainty, placebo allocation, study burden, optional elements and withdrawal choices clearly. Check understanding and allow time for questions.
Contacts and troubleshooting
Route questions to the right team
Protocol, eligibility, consent, withdrawals and general operational questions.
