The goal of this study (exploratory sequential design; mixed-methods study) is to evaluate whether a PERMA-H model mobile-based rehabilitation support program delivered to post-tracheostomy oral cancer patients can improve psychological and rehabilitation outcomes, compared with a control group receiving usual care/standard support. The study will focus on post-tracheostomy oral squamous cell carcinoma (OSCC) patients (aged ≥18 years) who are undergoing or scheduled to undergo tracheostomy followed by decannulation, and who have adequate communication ability and caregiver support. The main questions it aims to answer are: Does the PERMA-H model mobile-based rehabilitation support program improve patients' hope? (primary hypothesis/outcome measure 1) Does the PERMA-H model mobile-based rehabilitation support program improve patients' self-efficacy, perceived social support, and rehabilitation outcomes? (primary hypothesis/outcome measure 2) If there is a comparison group, researchers will compare the PERMA-H model mobile-based rehabilitation support program (intervention group) to a control group receiving standard/usual care (control group) to determine differences in outcomes between groups. Participants will be asked to complete the main study tasks, including: participating in qualitative interviews to explore their digital needs, expectations, and experiences regarding psychosocial care (Phase I); using the WeChat mini-program platform that incorporates a PERMA-H evidence-based module set and a chatbot (Decannulationbot / Digital rehabilitation Assistant, DDA) as part of the rehabilitation support program; completing validated assessments at study endpoints to measure hope (Herth Hope Index), self-efficacy (General Self-Efficacy Scale), and perceived social support (Perceived Social Support Scale), as well as rehabilitation-related outcomes (including rehabilitation willingness/participation and functional measures such as swallowing function and speech intelligibility as rated by speech-language pathologists). Expected outcomes include: comprehensive qualitative findings to inform the content and delivery of digital psychosocial support; a functional mobile intervention platform with evidence-based modules validated through expert appraisal and pilot testing; and statistically significant improvements in hope, self-efficacy, perceived social support, and rehabilitation outcomes in the intervention group compared with the control group.

Delays between surgery and the initiation of post-operative radiotherapy (S-PORT) in head and neck cancer (HNC) patients are prevalent and associated with worse oncologic outcomes. This pilot study evaluates whether a proactive, automated care coordination system (PRONTO-HN) can improve adherence to recommended S-PORT intervals of ≤42 days at the Centre hospitalier de l'Université de Montréal (CHUM). The study is a single-center, quasi-experimental, interrupted time-series design with two phases. Group A (control) includes patients treated before the intervention (using a prospectively maintained database from August 2024 to August 2025). Group B (intervention) includes patients treated with the new coordination system from September 2025 to September 2026. The intervention includes automated alerts, multidisciplinary task coordination, and risk stratification based on a predictive model developed and published by our team. This model uses only pre-operative data to estimate the likelihood that a patient will require adjuvant therapy after surgery, stratifying patients into high- and low-risk categories. High-risk patients receive intensified coordination protocols, including early oncology and dental consultations and shorter target times for pathology results. Primary objective: Reduce the proportion of patients with S-PORT \> 42 days. Secondary/tertiary objectives: Reduce mean S-PORT time. Evaluate impacts on overall, locoregional, and disease-free survival in a 2- and 3-year follow up study. Patients are identified at the time the operating room request is submitted. Demographic, clinical, and oncologic data are collected and stored securely in REDCap. As the intervention is administrative in nature and does not modify patient care, consent is waived. Statistical analysis will evaluate the intervention's effect and identify predictors of delays. A sample of 38 patients per group provides adequate power to detect a drop in S-PORT \> 42 days from 80% to 50%.
