Examining Clinical Presentation and Workup of Veterans with Irritable Bowel Syndrome in a Single Medical Centre: A Case Series.

Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction (DGBI) that affects about 10% of the adult population in the United States. IBS pathoetiology understanding has evolved and clinical management improved despite the underdevelopment of diagnostics. Within the Veterans Affairs (VA) system, the prevalence and impact of DGBIs are high. Yet there is a paucity of information on the patient demographic features. Our team examined the history and workup of patients referred to an IBS clinic within the VA's gastroenterology service through a systematic case series study to begin a quality improvement initiative.
