Digital Preparation for Bariatric Surgery: Feasability Pilot Trial

Metabolic and bariatric surgery (MBS) is in increasing demand due to the growing prevalence of severe obesity and the cumulating evidence of long-term benefits on weight loss, cardiometabolic and functional health outcomes, and quality of life for individuals living with severe obesity. The time spent on the waiting list for an MBS follow the same trend with an estimated waiting time of more than 18 months and rising. The lack of resources and multidisciplinary capabilities among MBS centers impacts the quality of care and outcomes, which greatly contributes to delayed surgery. In 2023, 31% of patients who had an initial appointment with the MBS nurse at the Quebec Heart and Lung Institute - Laval University(IUCPQ) did not proceed with the surgery due to fear, uncertainty, or timing issues. Additionally, 49% reported that their concerns (e.g., financial, home support) were not addressed before MBS. These data highlight the urgent need to implement strategies to optimize wait time and ensure that MBS preparation is tailored to patients' expectations. Telehealth has significantly impacted surgical preparation, including for MBS, by enhancing accessibility, reducing dropout rates, and maintaining clinical outcomes that are comparable to traditional in-person visits but it requires real-time multidisciplinary execution, limiting the applicability for MBS waiting list patients. An interesting complement to telehealth intervention is online education platforms which offer digital flexibility, a significant advantage over in-person session. To date, most MBS online resources are fee-based or driven by commercial interests and lack of clinical evidence, which raises concerns about their efficacy and safety for users who are seeking reliable support during their MBS journey. A free online education platform could optimize the time spent on the MBS waiting list by increasing patients' readiness for MBS, furnishing invaluable insights into the patient journey to MBS, and empowering individuals undergoing MBS. The IUCPQ is in the process of working on the care trajectory of patients with obesity. The Healthcare Direction and the Bariatric Surgery Clinic decided to use a platform called Precare. This platform offers personalized educational content as well as a calendar and appointment management system. It has been accredited by the Quebec Ministry of Health and Social Services. The present research focuses on the pilot testing the implementation and effectiveness of the PreCare solution for patients awaiting bariatric surgery at the IUCPQ. The objectives of the research proposal are: 1) To assess the usability and acceptability of the Precare platform using a mixed design methodology; 2) To evaluate the logistical feasibility of using the platform in a clinical setting; 3) To determine whether extensive self-questionnaire assessments may impact the use of the Precare platform; 4) To explore barriers and facilitators to enhance patient engagement and knowledge retention; and 5) To derive estimates variables related to gender, ethnicity, cultural background, learners and psychological profiles for future phases. Our hypotheses are: 1. The Precare platform will exhibit high usability and acceptability. 2. Testing the Precare platform in real clinical settings is viable and will yield promising results for improving patient readiness for Metabolic and Bariatric Surgery.

Mindfulness Training and Respiration Biosignal Feedback - Study 2

The goal of this research is to test usability and user satisfaction with a new breathing feature on the meditation app, Equa, to help young adults who are distressed, understand their physiological responses and mindfulness skill development during meditation. Our main aims are to test an algorithm that can use physiologic signals to give feedback about how participant physiology is changing during guided lessons on the meditation app, Equa through: * Assessing user satisfaction and usability * Measuring how much participant mindfulness skills are improving Participants will: * Complete a survey about demographics, their thoughts and feelings before and after the mindfulness meditation program * Complete 14 smartphone guided mindfulness meditation training units while physiological measures are being recorded * A subset of participants will see a graph tracking their physiological responses from the guided meditation lesson and predictive mindfulness skill scores * Complete a few brief questionnaires before and after mindfulness practices to understand potential changes in their mindfulness skills
