Controlling Faecal Incontinence With a Novel Anal Device: a Cost-effectiveness Trial

Not Applicable
Completed
Conditions
Faecal Incontinence
Interventions
Device: Navina anal insert
Other: Care as usual
Registration Number
NCT04657588
Lead Sponsor
Maastricht University Medical Center
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.

Primary Outcome Measures
NameTimeMethod
Change in FI severity8 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 Outcome Measures
NameTimeMethod
Frequency and severity of adverse events8 weeks

Any adverse events possibly related to the anal insert will be recorded

Cost effectiveness (Costs due to loss of productivity)8 weeks

Determined through the Productivity Cost Questionnaire (PCQ).

Mental health (anxiety)8 weeks

Measured through the Generalized anxiety disorder (GAD-7) questionnaire. This questionnaire contains 7 questions which can each be given a score of 0 to 3. A total score of 0= no anxiety (the best), a total score of 21= severe anxiety (the worst)

Mental health (depression)8 weeks

Measured through the Patient health questionnaire 9 (PHQ-9).

Adherence to therapy8 weeks

Checking whether patients in the anal insert group (intervention) decided to use the anal inserts or not

Cost effectiveness (direct medical costs)8 weeks

Determined through the Medical consumption questionnaire (MCQ).

Quality of life (QoL) (general QoL)8 weeks

Measured through the 5 level EQ-5D questionnaire (EQ-5D-5L). This questionnaire contains 5 domains (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) which can all individually be scored on a scale of 0 (best) to 5(worst). Additionally participants are asked to score their health for that day from a score of 0 (worst health you can imagine) to a score of 100 (best health you can imagine).

Quality of life (QoL) (disease specific QoL)8 weeks

Measured through the Faecal incontinence Quality of life scale (FIQL). This questionnaire contains 24 items which can be scored from 1( worst) to 4,5 or 6 (best) depending on the item. Patients can score a minimum of 29 points (worst QoL) to a maximum of 119 points (best QoL).

Wellbeing8 weeks

Measured through the ICEpop CAPability measure for adults (ICE-CAP-A) questionnaire. To measure wellbeing in terms of capabilities like attachment; security (thinking about the future without concern); role (doing things that make you feel valued); enjoyment and pleasure; control (independence). Each of the 5 items can be given a score of 1 (worst) to 4 (best).
