Pro-active Fecal Calprotectin Monitoring PROMOTE-UC

All patients in both control and intervention group will be contacted every 6 months until end of study. Partial Mayo and rectal bleeding score will be obtained and if there is an increase in partial Mayo score > 2 points from baseline or a rectal bleeding score > 1, this is considered as flare. Endoscopy will be performed wherever possible.

All patients in both control and intervention group will be asked every 6 months whether they were hospitalized, had undergone surgery, had used steroid (oral or rectal) or any biologics.

Choice of therapy for all patients should be according to the standard of care and by the judgement of the attending physician.

Quality of life is measured by Short Quality of Life in Inflammatory Bowel Disease (SIBDQ) questionnaire. Both control and intervention group will be asked to complete these questionnaires on-line during baseline, month 6, 12 and month 18.

The SIBDQ provide a measure of subjective health status or quality of life in patients with inflammatory bowel disease (IBD). It consists of four domains, bowel symptoms, emotional health, systemic systems and social function. The total score ranges from 10 (worst health) to 70 (best health).

Quality of life is measured by EQ-5D 5L health questionnaire. Both control and intervention group will be asked to complete these questionnaires on-line during baseline, month 6, 12 and month 18.

The EQ-5D-5L is a standardized measure of health status. It comprises of 5 dimensions like mobility, selfcare, usual activities, pain/discomfort, anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The patient is asked to indicate his/her health state. This decision results in a 1-digit number expressing the level selected for that dimension. The digits for 5 dimensions can be combined in a 5-digit number describing the respondent's health state.

Participants will be asked the number of physician visits during the course of the study.

Participants will be asked about time lost from work or school because of ulcerative colitis symptoms.

Endoscopic disease activity is measured by Mayo score. The Mayo Endoscopic Score is classified into the following four categories: 0, normal mucosa or inactive disease; 1, mild disease with erythema, decreased vascular patterns and mild friability; 2, moderate disease with marked erythema, absence of vascular patterns, friability and erosions; 3, severe disease with spontaneous bleeding and ulceration.

A histologic scoring index is a system used to assess the patient's disease severity using tissue sample. In this study, the Robarts Histology Index (RHI) is used. The RHI can be calculated as 1 x chronic inflammatory infiltrate (4 levels) plus 2 x lamina propria neutrophils (4 levels) plus 3 x neutrophils in epithelium (4 levels) plus 5 x erosion or ulceration (4 levels after combining Geboes 5:1 and 5:2).

Score takes into consideration histologic variables like crypt abscesses, presence of granulation tissue or aggregates of inflammatory elements in the superficial part of the mucosa, indicative of erosions or ulcers, neutrophils in the lamina propria.

Successful use of IBDoc home test kits will be measured by the completed test reported in the IBDoc portal.
