Study protocol for a randomised controlled trial to determine the effectiveness of a mHealth application as a family supportive tool in paediatric otolaryngology perioperative process (TONAPP)

Background: Otorhinolaryngology (ORL) surgery is common in children, but hospitalisation, surgery, and home care after discharge are stressful experiences for young patients and their family caregivers. Findings from literature highlight a lack of time in hospitals to support ORL surgery children and their caregivers through the perioperative process, along with the risks of caregivers' autonomous web or social media resources investigation. Therefore, this study aims to evaluate the effectiveness of a mobile health application with content to support ORL patients and their caregivers in the perioperative period to reduce caregiver anxiety and child distress compared to standard care. Methods: An open-label, two-arm randomised control trial design is being adopted. The intervention consists of a mobile health application with content to support ORL patients and their caregivers during the perioperative period. One hundred eighty participants will be enrolled and randomly assigned to the experimental group using the mHealth application or the control group. The control group receives standard information and education about the ORL perioperative period from healthcare providers orally or through brochures. The primary outcome is the difference between the intervention and control groups in preoperative caregiver state anxiety. Secondary outcome measures include children's distress before surgery and family preparation for hospitalisation. Discussion: The results of this study will be critical to the implementation of a new and safe model for the management of care and education in paediatrics. This model can achieve positive organisational and health outcomes by supporting continuity of care and empowering citizens to have informed participation and satisfaction in paediatric health promotion and management.
