BackgroundThe need for a more integrated, multidisciplinary approach to care for individuals with bleeding or clotting disorders has been highlighted in recent years. Evidence‐based education adapted to nurses’ needs is essential for a successful evolution. However, limited data currently exist on the clinical challenges nurses face in this specialty area.ObjectivesIdentify barriers and challenges faced by specialty nurses, and determine possible causes, to develop appropriate educational interventions.MethodsA mixed‐methods study, combining qualitative (semi‐structured interviews) and quantitative (online survey) data was conducted on the challenges experienced by hemostasis nurses in nine countries (Argentina, Australia, Canada, China, France, Germany, Spain, the UK, and the US), and deployed in five languages (English, French, German, Mandarin, and Spanish). Qualitative data were analyzed using thematic analysis. Quantitative data were analyzed using frequency tables, chi‐squares and standard deviations.ResultsParticipants (n = 234) included nurses (n = 212; n = 22 qualitative; n = 190 quantitative); and patients receiving care for bleeding or clotting conditions or their caretakers (n = 22 qualitative phase only). Through triangulated data analysis, six challenging areas emerged: (a) Understanding of von Willebrand disease (VWD); (b) Anticoagulant safety profile in specific patients; (c) Understanding the treatment of patients with inhibitors; (d) Patient risk assessments; (e) Individualization of care and communication with patients; and (f) Accessing and implementing relevant professional education.ConclusionsThis needs assessment provides a comprehensive illustration of the current challenges faced by nurses in the field of bleeding and clotting disorders, and indicates where gaps in skills, knowledge or confidence would benefit from nurse‐specific educational programming.

Two male first cousins with mild haemophilia A had baseline factor VIII levels of 12-15% and experienced bleeding requiring coagulation factor infusion therapy with trauma and surgical procedures. Both the patients with haemophilia A also had electrocardiographically documented symptomatic paroxysmal atrial fibrillation (PAF) for several years that had become resistant to pharmacological suppression. Radiofrequency ablation was considered in both the cases but deferred considering refusal of consent by the patients to undergo the procedure. Remission of arrhythmias has been reported in patients with iron-overload syndromes. Body iron stores assessed by serum ferritin levels were elevated in both men but neither had the C282Y or H63D genes for haemochromatosis. Calibrated reduction of iron stores by serial phlebotomy, avoiding iron deficiency, was followed by remission of symptomatic PAF in both cases. Iron reduction may be an effective treatment for arrhythmias apart from the classic iron-overload syndromes and deserves further study particularly in patients with bleeding disorders who might be at risk for arrhythmias and other diseases of ageing.

5100 Two male first cousins with mild hemophilia A had symptomatic electrocardiographically documented paroxysmal atrial fibrillation for several years that had become resistant to pharmacologic suppression. Both had baseline factor VIII levels of 12 to 15% and experienced bleeding requiring coagulation factor infusion therapy in response to trauma and surgical procedures. Radiofrequency ablation of ectopic electrical foci was considered in both cases but deferred because anticoagulation required to prevent thromboembolic complications of radiofrequency ablation carried an unacceptably high risk of bleeding. Iron accumulation with aging has been implicated in the pathogenesis of cardiovascular disease in general and arrhythmias in particular. Uncompensated iron-catalyzed oxygen free radical formation accounts for such toxicity. Remission of arrhythmias has been reported with iron reduction therapy in patients with iron overload disorders. Effects of iron reduction on arrhythmias in settings other than iron overload syndromes are unknown. Body iron stores as assessed by serum ferritin levels were elevated in both men (389 and 305 ng/ml respectively) but neither had the C282Y or H63D genes for hemochromatosis. Calibrated reduction of iron stores by serial phlebotomy, avoiding iron deficiency, was performed and was followed by sustained remission of PAF in both cases. These findings suggest that iron reduction with maintenance of ferritin levels below about 100 ng/ml may be effective treatment for arrhythmias apart from the classic iron overload syndromes. Effects of primary prevention of iron accumulation over time and reduction of existing elevated iron stores deserve further study in patients with bleeding disorders in whom standard treatment of diseases of aging may be costly and carry high risk. The efficacy, safety, simplicity and cost effectiveness of iron reduction therapy commends application of this investigational approach to disease prevention and treatment in the general population.
