Patient reported outcomes (PROs) are important measures of how well treatment works in Crohn's disease (CD). PROs are symptoms reported directly by patients, rather than tests like colonoscopies or blood work. The PRO Measurement Information System (PROMIS) is a new scale for measuring PROs for physical, mental and social health. The results can be compared to those from people that don't have IBD. A gastrointestinal (GI) PROMIS scale was recently developed. The GI scales were not studied in large numbers of Crohn's patients, but were studied in people all across the United States. We studied these questions in 1839 people with Crohn's disease in CCFA Partners. Most (75%) were women. People with Crohn's disease reported more fatigue, anxiety and pain compared to people without Crohn's disease. People with Crohn's disease reported less reflux, problems swallowing and constipation than people without Crohn's disease. Other GI symptoms for people with Crohn's disease were similar to those reported by people without Crohn's disease. Compared to people in remission, people with active CD reported worse symptoms on the GI-PROMIS scales for all symptoms except problems swallowing and constipation. Those with a worse quality of life, as measured by the Short IBD Questionnaire (SIBDQ), reported worse symptoms on the GI-PROMIS scales all symptoms. People who reported more nausea, diarrhea, gas/bloat and abdominal pain reported more psychosocial symptoms on the PROMIS scales. In summary, those with worse symptoms on the GI-PROMIS scales scored worse disease activity scales, quality of life scales and more symptoms of depression and anxiety. These scales could be important ways to measure symptoms in the future.
