Overview
Brief Summary
The purpose of this study is to assess the cost-effectiveness and improvement in quality of life of using a novel anal insert (navina)
Detailed Description
After being informed about the study including the potential pros and cons, patients will be given a minimum of 7 days to think about whether they would like to participate in the study. If they would like to participate, and informed consent form will need to be signed, after which the patients will undergo a screening to ensure they meet the inclusion criteria. A 2 week run-in period will take place to let patients get used to filling in an electronic daily diary. Prior to this period, patients will be asked to fill out several questionnaires. After this period, randomisation into either (1) the anal insert group or (2) the care as usual group. Group 1 will then have an 'accommodation' week in which they can try out two different sizes of the anal insert to see which size they would prefer for the treatment period. The treatment period will consist of 8 weeks In which the (1) anal insert group is expected to use the anal inserts and the (2) care as usual group is asked to continue with their treatment as usual. During the treatment period, patients will fill out an electronic daily diary as well as weekly questionnaires.At the end of the 8 week treatment period, patients will fill out additional questionnaires. The follow-up consists of 4 weeks, after which patients will be asked again to fill out several questionnaires.

- •Aged between 16-90 years
- •patients who experience at least 1 episode of accidental bowel leakage during the 2 week run-in period will be eligible for randomisation.
Exclusion Criteria

Outcomes
Primary Outcomes
Change in FI severity
Time Frame: 8 weeks
Measured using the St. Marks/vaizey incontinence score. This scale ranges from 0 (complete continence = best score) to 24 (complete incontinence= worst score). We are particularly interested in whether a clinically meaningful decrease of ≥3 points will occur in the intervention group compared to the control group.
Secondary Outcomes
- Frequency and severity of adverse events(8 weeks)
- Cost effectiveness (Costs due to loss of productivity)(8 weeks)
- Mental health (anxiety)(8 weeks)
- Mental health (depression)(8 weeks)
- Adherence to therapy(8 weeks)
- Cost effectiveness (direct medical costs)(8 weeks)
- Quality of life (QoL) (general QoL)(8 weeks)
- Quality of life (QoL) (disease specific QoL)(8 weeks)
- Wellbeing(8 weeks)
