©Neurogut 2018 FECAL INCONTINENCE STOOL DIARY INSTRUMENT Basic description: The Fecal Incontinence Stool Diary Instrument (FISDI) is a list of patient-reported symptoms for the evaluation of accidental stool leakage also known as fecal Incontinence, and other bowel problems associated with this condition. Fecal incontinence affects 9% of the adult US population and at least 25% of nursing home residents. Fecal incontinence is associated with multiple bowel and stool-related symptoms. Because of the irregular and unpredictable nature of bowel habit, including accidental loss of stool and or gas, and difficulty with either remembering or recalling these symptoms, a prospective assessment of patient-reported bowel and stooling-related symptoms is important, both for use in clinical trials, and for the assessment of patients with fecal incontinence. Authors: Neurogut Incorporated (USA) Objective: To assess the presence and severity of patient-reported bowel, stool and abdominal symptoms related to accidental stool leakage (fecal incontinence), for use in clinical trials, and assessment of patients with fecal incontinence Therapeutic Areas: Gastrointestinal and Digestive System Diseases Pathological conditions, Signs and Symptoms Therapeutic indications: Fecal Incontinence Dyssynergic defecation Anorectal and Colorectal diseases Urinary incontinence Pelvic floor problems Type of Clinical Outcome Assessment (COA) Patient Reported Outcome (PRO) assessment Original language English for the USA Bibliographic reference for the original questionnaire: 1.
