Giving intravenous iron to patients with symptomatic heart failure is safe and cost effective.

Abstract

Heart failure affects approximately 1 million people in the UK, adversely affecting quality of life, functional capacity and cognitive health. Iron deficiency complicates heart failure in approximately 50% of patients. Giving intravenous ferric carboxymaltose has been shown to improve quality of life in patients with heart failure (New York Heart Association class and Kansas City Cardiomyopathy Questionnaire). A quality improvement project was designed to assess the feasibility, safety and cost implications of establishing an intravenous iron service in the authors' centre. Between July and December 2019 61 patients who were screened met the inclusion criteria and were administered intravenous ferric carboxymaltose. There were statistically significant improvements in ferritin levels (83.3 ug/litre to 433 ug/litre; P<0.0001), transferrin saturation (18% to 30% P<0.0001) and haemoglobin levels (126 g/litre to 135 g/litre; P<0.01). No demonstrable changes in New York Heart Association class or quality of life scores were noted. The overall financial impact for the trust was income generation of £14 665, a net income of £240 per patient. Intravenous iron replacement with ferric carboxymaltose is safe and cost effective, and should be considered in eligible iron-deficient patients with symptomatic heart failure. Integration with another day case intravenous service represented the most logistically simple and economically viable method of service delivery.
