Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A clinically meaningful decrease in severity of faecal incontinence after the 8-week treatment period, measured using the St. Marks/Vaizey incontinence score (range 0-24) defined as a decrease of >= 3 points. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Quality of life both general and disease specific after 8 weeks of treatment measured using the EQ-5D-5L and Faecal Incontinence quality of life (FIQL) scales respectively. - Cost effectiveness as determined by calculations incorporating total treatment costs and changes in EQ-5D-5L (QALYs gained) and MCQ/PCQ results (savings from reduced medical resource use and increased work productivity respectively). - Adherence to therapy - Psychological characteristics; specifically anxiety and depression (tested using the Generalized Anxiety Disorders Assessment (GAD7), the Patient Health Questionnaire (PHQ9, to assess depressive symptoms). In addition, we will administer the Dutch ICE-CAP-A, a questionnaire that measures 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). - Number and severity of adverse events | — |
