Improving the management of iron deficiency in ambulatory heart failure patients.
Based on clinical trial data patients with heart failure (HF) and evidence of iron deficiency should be offered intravenous (iv) iron with the aim of improving exercise capacity and symptoms. Baseline measurement in outpatient HF clinics demonstrated that only 50% of patients who may be eligible for iv iron were investigated with iron studies. Our aim was to make sure that 90% of the patients attending our heart failure clinics who were symptomatic and had an ejection fraction (EF) ≤45% should have their iron studies checked within the last six months. In an effort to increase the proportion of suitable patients in whom iron studies are requested, we carried out three plan-do-study-act (PDSA) cycles each with a different intervention. These interventions included a presentation of the clinical trial evidence at a HF multidisciplinary meeting, email reminders prior to clinic and stickers in the patient notes (repeated twice). The effect of each intervention was measured with the outcome being the proportion of eligible patients in whom iron studies were documented within the previous 6 months. The interventions increased the number of suitable patients who had iron studies checked, to as high as 100%, however this effect was not sustained. Root cause analysis revealed that clinicians were unenthusiastic to continue performing iron studies due to inefficiency in the process of admitting patients and giving them iv iron. For example median in-hospital stay of seven hours for an infusion that is given over 15 minutes. In an attempt to improve patient and physician satisfaction we piloted an ambulatory outpatient service to deliver iv iron. We demonstrated that this service was feasible and more efficient as less time was required waiting for a bed or spent in hospital and was less costly. In summary we have demonstrated interventions which can increase the identification of patients who would benefit from iv iron and piloted a new time and cost efficient system of administration of iv iron.
