Nurse-led approach to standardising the management of iron-deficiency anaemia, achieving the 2-week cancer pathway targets and reducing hospital admissions: practicalities and learnings from a success story

Abstract

The most significant and common cause of anaemia is iron deficiency, which occurs when iron absorption cannot meet the body’s demands due to growth, pregnancy, poor nutrition, malabsorption or blood loss. It is estimated that in the UK 11% of the adult population have iron-deficiency anaemia (IDA) and investigation is essential to exclude significant pathology as the underlying cause. It has been shown that IDA is responsible for 57 000 hospital admissions in the UK, and at least 10% of gastroenterology referrals per annum. IDA is a major red flag symptom for gastrointestinal cancer. At the Royal Liverpool University Hospital, a dedicated nurse-led IDA service was developed in 2005 to help alleviate the clinical pressures created by the two week suspected cancer referral pathway. With the success of this service, investigation and management of IDA has been extended to referrals from accident and emergency, with the aim of reducing hospital admissions and to investigating and optimising iron replacement therapy in preoperative patients. Delivering this as a nurse consultant-led service was proposed by the gastroenterology medical team who felt that, as a clinical problem with well established, published investigative algorithms, IDA would be suitable for management in a dedicated nurse-led clinic. This article will focus on the strategies employed to achieve sufficient resources and clinic capacity to run this service effectively, develop strong nurse education and training, and the development of agreed investigation pathways. A robust results review process, with rapid management of abnormal results, was established with timely discharge for those patients with normal results. Optimisation of iron replacement therapy and verification of sustained haematological response was prioritised as this was identified as being poorly managed across all specialties. A process for ongoing audit of results was included to show the success of the service and highlight areas for redesign. Here, we demonstrate the effectiveness of our nurse-led IDA service and suggest it as the basis for other IDA services in the UK and beyond.
