Clinical Tools
Bowel Function Index
The BFI provides a numerical assessment score for prior 7 days based on ease of defecation, feeling of incomplete evacuation, and personal judgment of constipation.
Patient Assessment of Constipation (PAC-SYM)
This 12-item questionnaire of patient-reported symptoms assesses 3 subscales of symptoms (bowel movements, rectal symptoms, and abdominal symptoms) over the 2 prior weeks.
Bristol Stool Form Scale
This visual scale is used to classify the type of stools passed.
Patient Education Tool
This patient education tool list items that patients can do at home to help ease their opioid-induced constipation and includes a list of questions to ask the doctor or clinic about constipation.
