Background:
Chronic intestinal failure (CIF) is an ultrarare disease, with an estimated national prevalence of ∼25,000 cases. There is a suspicion of widespread lack of expertise in CIF care, but no formal assessment tool or data exist. We developed and validated a knowledge test in CIF and now report our preliminary results from testing CIF knowledge in a cohort of US gastroenterologists.
Method:
We developed a 20-question knowledge test in CIF, covering four key components of IF. After internal testing, refinement, and revision, we administered the test to a convenience sample of experts and nonexperts in IF. We then deployed the validated test to a cohort of 100 US gastroenterologists.
Results:
The test had a Cronbach alpha of 0.74, suggesting a reliable test, with a threshold score to discriminate experts and nonexperts of 13.4 (maximum 20) and with a sensitivity of 81.3% and specificity of 86.4%. The overall mean score of 8.2 for the 100 US gastroenterologists was at the level of nonexperts in our convenience sample.
Conclusion:
The preliminary results of our validated knowledge test in IF among a broad group of US gastroenterologists demonstrate lack of knowledge in IF.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
