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

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

The purpose of this study is to assess the cost-effectiveness and improvement in quality of life of using a novel anal insert (myMiracle)

Study Overview

• Status: Recruiting
• Conditions: Faecal Incontinence
• Intervention / Treatment: Device: myMiracle anal insert; Other: Care as usual

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Anal insert; This group will be asked to use anal inserts to help manage their faecal incontinence during the treatment period	Device: myMiracle anal insert; The myMiracle device is a single-use, pre-lubricated, liquid-filled rectal insert with a plastic applicator. The insert is filled with liquid mineral oil. The primary advantage of this new instrument is the fact that the liquid-filled insert will move and adapt as the fluid is transferred throughout the device making it easy to insert/remove and comfortable to wear. The design is intended to adjust to the contours of the individual anatomy to prevent leakage.; Other Names: anal plug
Sham Comparator: Care as usual; This group will be asked to continue with their care as usual (e.g. incontinence pads)	Other: Care as usual; Care as usual means participants are to continue their usual treatment for FI, like they would if they would not have participated in this study.; Other Names: Comparator

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in FI severity	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.	8 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cost effectiveness (direct medical costs)	Determined through the Medical consumption questionnaire (MCQ).	8 weeks
Cost effectiveness (Costs due to loss of productivity)	Determined through the Productivity Cost Questionnaire (PCQ).	8 weeks
Mental health (anxiety)	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)	8 weeks
Mental health (depression)	Measured through the Patient health questionnaire 9 (PHQ-9).	8 weeks
Quality of life (QoL) (general QoL)	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).	8 weeks
Quality of life (QoL) (disease specific QoL)	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).	8 weeks
Adherence to therapy	Checking whether patients in the anal insert group (intervention) decided to use the anal inserts or not	8 weeks
Wellbeing	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).	8 weeks
Frequency and severity of adverse events	Any adverse events possibly related to the anal insert will be recorded	8 weeks
