Principles for Assessing Quality of Life in Patients With Crohn's Disease.

Crohn's disease (CD) is a lifelong inflammatory bowel disease that can severely impact quality of life. Many questionnaires exist to assess quality of life for patients with CD, but some of these questionnaires were developed without qualitative data from patients or include only limited symptoms. Patient-Reported Impact of Symptoms in CD provides an innovative and patient-centered framework for assessing quality of life in patients with CD, soliciting qualitative data from patient interviews, and using this to guide a cross-sectional study. Their findings should inform how clinicians guide conversations with their patients regarding quality of life.
