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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Arm 1: Control arm | No Intervention | Participants will follow the standard protocols of preparation for a bariatric surgery and remain on the waiting list without access to the educational platform (Precare). Participants will have to fulfill the participant's description module and the readiness assessment. After the 6-month assessment, the patient will be providing a full access to Precare and will follow the same assessment process as arm 3 (i.e., Precare usability module, and the secondary clinical assessment module). | |
| Arm 2: active arm with a short assessment | Experimental | Participants randomized to the active arm with a short assessment (arm 2) will be provided with 6-month of full access to the educational platform Precare and will have to fulfill the participant's description module and the readiness assessment (same as arm 1), as well as the Precare usability module. |
|
| Arm 3: active arm with a full assessment | Experimental | Participants randomized to the active arm with a full assessment (arm 3) will be provided with 6-month of full access to the educational platform Precare after having fulfilled a REDCap module, including the participant's description module, the readiness assessment, the Precare usability module, and the secondary clinical assessment module. |

| Self-perceived barriers to metabolic and bariatric surgery | Short questionnaire to assess the barriers to the decision for bariatric surgery perceived by patients based on Luck-Sikorski C, Jung F, Dietrich A, Stroh C, Riedel-Heller SG. Perceived Barriers in the Decision for Bariatric and Metabolic Surgery: Results from a Representative Study in Germany. Obes Surg. 2019 Dec;29(12):3928-3936. doi: 10.1007/s11695-019-04082-1. PMID: 31301032. | At baseline |
| eHeals Literacy Scale | Survey to measure Participants' feelings about their use of the Internet as a tool for obtaining health-related information. We will use the validated french version of the eHeals scale, a 10-item questionnaire. Question's response is measured with a 5 point likert scale with response options either going from 'strongle disagree' to 'strogly agree', 'not at all; usefull' to 'very usefull' or ' Not at all important' to 'Very important'. Higher scores represent higher sefl-perceive eHeals literacy. | At baseline |
| Index of Learning Styles | To assess of the learner profile of the patient (44 items) Adapted from the Index of Learning Styles Questionnaire by Barbara A. Solomon & Richard M. Felder University of North Carolina Raleigh, NC 27695 | At baseline |
| University of Rhode Island Change Assessment Scale (URICA) | 32-item scale based on Prochaska and DiClemente's transtheoretical behaviour change model to assess the readiness of the patient to bariatric surgery. Each question is measured on a 5-point Likert scale with response options ranging from "strongly disagree"(1 point) to "strongly agree"(5 points). Questions are divided into four subscales of 8 items each: precontemplation, contemplation, action and maintenance. Each subscale score from 1 to 40. The readiness to bariatric surgery score is calculated by adding the scores from the Contemplation, Action and Maintenance subscales and subtracting from that sum the Precontemplation subscale score. The total score ranges from 1 to 160, with higher scores indicating better readiness. |
| Measure | Description | Time Frame |
|---|---|---|
| Mental Health Continuum Short Form | 14-item questionnaire to assess overall psychopathology. Each question is measured on a 6-point Likert scale with response options ranging from "Never"(0 point) to "Everyday"(5 points). Total score ranges from 0 to 70, with a higher score representing better mental well-being. (Only for arm 3) | At baseline, 3 months and 6 months |
