Abstract
Today, professional nurses around the world are stepping up to meet the needs of individuals with Crohn disease, using their specialized knowledge and skills that demonstrate areas of expertise that have not always existed. The gastrointestinal-specific knowledge being used by these 21st-century nurses exists today because progressive efforts of nurses in previous decades moved the profession of nursing forward. The purpose of this article was to describe and analyze the development of the role of nurses in responding to new challenges patients with Crohn disease face since the emergence of the disease in the early 20th century. The authors used traditional historic research methods to conduct the study. Primary sources include nursing journals and textbooks published in the 20th and 21st centuries and documents archived at The Mount Sinai Hospital in New York City, where Burrill B. Crohn conducted his seminal work. The significance of the findings is that the changing role of nurses in caring for patients with Crohn disease mirrors the professionalization of nursing during the 20th and early 21st centuries.
