Study Arms (1)
Patients with IBD
1. Patients with IBD in longstanding remission (\>2 years) (maximum of 20 patients) 2. Patients with IBD recent event (diagnosis or flare of IBD) (\<1year) (minimum 20 patients) 3. Additional patients with IBD in standard follow up.
Interventions
1. All participants will receive a wearable device type Corsano Health Cardio watch 287-2 which is provided by the sponsor via Inovigate. Participants will be encouraged to wear the device 24h per day and need to wear the wearable device at least 12 hours per day, preferential during daytime. 2. All participants will receive a loyalty card (Xtra card Colruyt group) which is provided by the sponsor via Inovigate for food data capturing. The patient is requested to execute all grocery shopping at one of the Colruyt Group stores. He/she will always need to offer the loyalty card to the cashier prior to payment. The purchase receipt will then be automatically sent to the central food data repository at the sponsor set up for this study. Non-food or non-food related data will neither be captured nor stored during the trial. 3. biomarkers in blood and feaces will be monitored according to standard of care 4. patient reported outcomes will be monitored according to standard of care
Eligibility Criteria
This is an open label observational trial with partially blinded data collection (wearable and shopping data blinded for the patient and treating HCP). Patients in the study will not be randomized. Patients will be recruited via planned outpatient visits and day clinic admissions. Patients will be allocated to one of the three target patient groups at the investigator's discretion. 1. Patients with IBD in longstanding remission (\>2 years) (maximum of 20 patients) 2. Patients with IBD recent event (diagnosis or flare of IBD) (\<1year) (minimum 20 patients) 3. Additional patients with IBD in standard follow up. From the moment 60 patients are included, no additional patients can be recruited in group 1 or 3 prior to completion of group 2.
You may qualify if:
- Males or females aged \> 18 years
- Diagnosis of CD, UC or IBD-unspecified for at least 1 month
- Treatment with conventional or advanced therapy for IBD at initiation of the study
- The patient must have access to an email address
- The patient must be willing to perform all the groceries shopping at any of the Colruyt Group stores during this study, using an Xtra card created by the study team.
- Capacity to independently answer regular digital questionnaires
- Capacity and willingness to use a smartphone and activity tracker
You may not qualify if:
- Planned extended (\> 1 month) overseas travel during the study period of 12 months, if internet access would be impossible, inconvenient or unaffordable during this time
- Previous colectomy
- Inability to communicate well with investigators or unable to comply with the study requirements
- Significant medical condition interfering with physiological measurements trough a wearable device (heart failure, pacemaker or defibrillator)
