This is a non-interventional cohort study. Patients will be included over a 6-month period during a scheduled multimodal day hospital visit as part of their care. Before their day hospital appointment, patients will receive an information sheet explaining the research process.
M0 Inclusion:
Patients who agree to participate in the research will receive evaluation questionnaires to be completed online, which include:
* Access to care,
* Adherence according to the self-declared adherence rate,
* Knowledge about their disease (IBDKID2),
* Fatigue (FACIT-F),
* Dietary questionnaire (SLFQ),
* Productivity (WPAI). Patients who do not wish to participate in the study during their visit to the multimodal day hospital will be excluded from the study.
Day of DH:
Upon arrival at the multimodal day hospital, if the questionnaires have not been completed in advance, patients will be offered the opportunity to complete them during their visit, with an estimated duration of 30 minutes.
M1 (4 Weeks Post-DH):
Four weeks after the day hospital visit, patients will receive an email with a link to complete the questionnaires again (adherence, knowledge of their disease, fatigue, dietary questionnaire, and productivity). If the questionnaires are not completed, a reminder email will be sent 3 days and 1 month after the due date. If there is no response, a phone call will be scheduled 1 week after the initially planned date by the clinical research technician. Questionnaires can be filled out up to 8 weeks after inclusion.
M6 (6 Months Post-DH):
Six months after the day hospital visit, patients will again receive an email with a link to complete the questionnaires (adherence, knowledge of their disease, fatigue, dietary questionnaire, and productivity). A reminder email will be sent 3 days and 1 month after the due date if there is no response. If there is still no response, a phone call will be made 1 week after the initially scheduled date by the clinical research technician. Questionnaires can be completed up to 7 months after inclusion.
Between M0 and M1:
Treatment optimization and the update of the vaccination schedule will be recorded in the patient's electronic health record.
Study Participation End:
Participation in the study will conclude after the completion of the questionnaires, no later than 7 months after inclusion Statistical analysis The analysis will be performed using SAS v9.4 software (or a later version) by the URC-Est at the end of the study after the database freeze. A detailed statistical analysis plan will be written before the database freeze. A flow chart will be created.
The patient profile at inclusion will be described, including comorbidities, characteristics of the IBD (such as clinical and biological activity at the time of the day hospital visit), and treatments. The day hospital process will be evaluated, including the number of patients per session and the type of interventions performed.
Qualitative variables will be described by their frequency and count, while quantitative variables will be described by their mean and standard deviation or by their median and interquartile range, depending on their distribution.
Analysis of the Primary Endpoint The proportion of patients with an improvement in their skills at one month or an improvement in the management of their disease will be calculated. The proportion of patients with improvement in each of the two groups of criteria will also be calculated.
Analysis of Secondary Endpoints Secondary endpoints will be measured by the proportion of patients showing improvement for each individual item. The total number of items with improvement per patient will also be evaluated, as well as the proportion of patients with access to practitioners such as a dietitian specialized in IBD, a rheumatologist, or a dermatologist outside the day hospital, based on the dedicated questionnaire.
A logistic regression will be conducted to identify the predictors of improvement in patient skills or disease management, based on patient characteristics, IBD features, and treatments.
