The aim of the study is to understand the early experiences of Feraccru® in patients with inflammatory bowel disease (IBD) and iron deficiency anaemia (IDA) in the UK, including treatment effectiveness, patterns of use and tolerability. By describing the characteristics of patients treated with Feraccru® and their outcomes, this study will provide the medical community with important information to support treatment decisions for their patients. This will ultimately support improvements to patient care, including the long-term outcomes of patients with IBD and IDA
