An Audit of Iron Deficiency in Hospitalised Heart Failure Patients: A Commonly Neglected Comorbidity.
AlAayedi, Khalid
Introduction
Iron deficiency (ID) is a common comorbidity in patients with heart failure (HF) and can significantly impact morbidity and mortality, regardless of the presence of anaemia.
Aim
This audit aimed to assess the current practice in diagnosing and assessing iron deficiency (ID) in hospitalised patients with heart failure and reduced ejection fraction (HFrEF). The primary goal was to determine the prevalence of ID in HF patients and the frequency of iron testing in those patients. Additionally, the secondary aims included evaluating the presence of anaemia, the length of hospital stay, and the adequacy of appropriate management for iron deficiency in this patient population.
Methods
A retrospective audit was conducted, reviewing data from patients admitted to St. Vincent University Hospital over a period of 4 months.
Results
Out of the 111 patients audited, only 74% (82) had their iron status checked, and among those tested, 63% (52) met the criteria for iron deficiency according to the European Society of Cardiology (ESC). Additionally, 54% (28) of iron-deficient patients were also anaemic. Iron replacement was administered to 34 out of the 52 patients diagnosed with iron deficiency, accounting for 65% of the identified cases. The average duration of hospital stay for patients with iron deficiency was 13.8 days, while those without iron deficiency had a shorter mean length of stay of 11.2 days. However, it is important to note that the presence of co-morbidities and other confounding factors might have influenced these results.
Conclusion
Despite guideline recommendations, iron deficiency remains under-recognised and undertreated in clinical practice among heart failure patients. There is a crucial need for increased awareness, education, and practical guidance to improve the screening, diagnosis, and management of iron deficiency in hospitalised heart failure patients.
