©NEUROGUT 2018 CONSTIPATION STOOL INSTRUMENT
Basic description: The Constipation Stool Instrument (CSI) is a list of patient-reported symptoms for the evaluation of bowel problems associated with constipation. Constipation affects 15% of the US population. Constipation comprises of multiple symptoms that describe the frequency and difficulty with bowel movements. Because of the irregular nature of bowel habit, the multiple and variable symptoms, and difficulty with remembering symptoms as well as recall bias, it is important to prospectively assess patient-reported bowel symptoms, for use in clinical trials, and for the assessment of patients with constipation.
