NCT07258589

Brief Summary

A multicentre non-blinded randomised intervention trial with a parallel cluster design. The multicentre study will be performed at 12 hospitals in the Netherlands. A parallel cluster design per hospital was selected to prevent contact between participants in the same hospital who are randomised into different study arms. Such contact may result in bias as it may allow for patients in the control arm to be informed about elements of taste and smell training. To examine the effect of at-home taste and smell training versus standard care on taste function and other outcome parameters, measurements will take place at baseline (before the training starts), and after 12 weeks. The intervention will take place at home. The control group will receive usual care. Questionnaires will be filled in online at home, while taste and smell tests and saliva collection will be conducted either at home or in the hospital during regular visits. Patients in both study arms are contacted by their dietitian every 3 weeks.
