Abstract
Introduction
Iron deficiency Anemia (IDA) is a common complication of inflammatory bowel disease (IBD). High prevalence of IDA in IBD suggests suboptimal surveillance and treatment. Oral iron is poorly tolerated, associated with worsened disease activity, and often insufficient to reverse anemia in IBD patients. Intravenous (IV) iron is favored for treatment of IDA in IBD in most clinical scenarios and many guidelines recommend IV iron as first line for IBD patients. Regardless, oral iron is prescribed commonly for IDA in IBD. The objective of this study is to determine practice patterns of primary care physicians (PCP) and gastroenterologists (GI) in the management of IDA in IBD.
Methods
We anonymously surveyed GI and PCP attendings and trainees at Saint Louis University School of Medicine in St. Louis, Missouri, using paper self-administered instruments. We asked about practice patterns in the management of IDA in IBD patients and knowledge of IV iron. The study questionnaire was developed based on United States expert opinion consensus statements and European guideline recommendations published in the Journal of Crohn’s and Colitis and Inflammatory Bowel Diseases.
Results
Of GI responders, 92.3% were fellows, 7.7% were attendings; of PCP responders, 81.8% were residents, 18.2% were attendings. 15.4% GIs, 12.7% PCPs were very comfortable managing IBD patients with IDA; 76.9% GIs, 58.2% PCPs were somewhat comfortable; 7.7% GIs, 29.1% PCPs were not comfortable (p=0.275). 61.5% GIs, 25.5% PCPs always check iron studies when evaluating anemic IBD patients; 30.1% GIs, 21.8% PCPs check most of the time; 7.7% GIs, 34.5% PCPs sometimes check; 0% GIs, 12.7% PCPs rarely check; 0% GIs, 5.4% PCPs never check (p =0.05). In mild Crohn’s disease with severe anemia, 15.4% GIs, 41.8% PCPs would prescribe oral iron daily; 15.4% GIs, 12.7% PCPs would prescribe oral iron every other day; 69.2% GIs, 45.5% PCPs would prescribe IV iron (p=0.58). 0% GIs reported good knowledge of IV iron, 53.8% reported acceptable knowledge, and 46.1% reported poor knowledge. 7.7% GIs, 10.9% PCPs reported good knowledge of how to order IV iron; 53.8% GIs, 7.3% PCPs reported acceptable knowledge; 38.5% GIs, 81.8% PCPs reported poor knowledge (p=0.000215). 23.1% GIs, 61.8% PCPs thought PCPs were responsible for screening for IDA in IBD patients; 76.9% GIs, 36.4% PCPs thought GIs were responsible (p= 0.0131).
Discussion
Both PCPs and GIs perceived responsibility to manage IDA in IBD patients. PCPs were less likely than GIs to screen for IDA in anemic IBD patients or to report adequate knowledge of clinic processes to order IV iron. Future efforts to reinforce gastroenterologists’ role in the management of IDA in IBD and to bolster familiarity with IV iron and its indications might improve outcomes and quality of life for IBD patients.
