The burden of atrial fibrillation in the Netherlands.

BACKGROUND: Atrial fibrillation (AF) is the most common sustained atrial arrhythmia and it is independently associated with an increased morbidity and mortality. As a result of the high prevalence of AF, the economic and clinical impact of the disease is substantial. This study describes the economic and clinical impact of AF in the Netherlands. METHODS: Epidemiological data on AF in the Netherlands were projected on population estimates of the Netherlands in 2009 and combined with data on the cost of AF and its interventions. RESULTS: Overall prevalence of AF in the Netherlands is 5.5% in the population over 55 years, corresponding to about 250,000 AF patients. The prevalence increases with age, and the mean age of AF patients is 69.3 years. Incidence of AF in the Netherlands varies with age, from 1188 new cases in the age group of 55 to 59 up to 7074 new cases in the age group 75 to 79. Total new cases amounts to 45,085 patients per year in the Netherlands. Total costs of AF in the Netherlands are 583 million, of which the majority (70%) were accounted for by hospitalisations and in-hospital procedures. Pharmacotherapeutic management of AF totalled 17 million in the Netherlands in 2009. DISCUSSION: AF is a serious disease with a high clinical and economic burden, especially due to hospitalisations as a result of cardiovascular events. The number of patients with AF in the Netherlands is considerable and will increase with the ageing population in the future.

Cost of severe haemophilia in Toronto.

Our objective was to determine costs and trends in treating boys with severe haemophilia A before our centre routinely used prophylaxis. One reviewer extracted data from patient charts to determine resource consumption for 17 boys with severe haemophilia A from 1978 to 1998 at Toronto's Hospital for Sick Children. Resources included factor concentrate, doctors and health care professionals (physiotherapists/social workers), tests (laboratory, radiological and diagnostic) and hospitalizations. Subgroup analysis on those patients infected with HIV and/or hepatitis were also performed. Costs in Canadian Dollars were taken from standard lists and discounted at 3%. Total average cost (range) 62 292 dollars (3339-121 738) per year patient(-1); the largest fraction, 59 910 dollars (3103-119 480), 96.2% was accounted for by factor VIII. Hospitalizations accounted for 1832 dollars (0-5217) per patient year(-1) including drugs, nursing care and stay. Doctor and health care professionals visits averaged 252 dollars (36-462) and 72 dollars (0-175) per patient year(-1), laboratory and other tests cost 201 dollars (22-377) and 26 dollars (2-60) per patient year(-1), respectively. The average number of bleeds was 12.9 (2.0-22.0) per patient year(-1), decreasing since 1977 by 0.68 per patient year(-1) (R(2) = 0.56). Hospitalizations averaged 0.22 (0-4) per patient year(-1), lasting 2.3 days. From 1984, hospitalizations decreased by 0.025 patient(-1) year(-1) (R(2) = 0.76). Concurrently, the average treatment costs increased by 5456 dollars patient(-1) year(-1) (R(2) = 0.81). Clotting factor concentrate cost per patient increased by 5521 dollars year(-1) (R(2) = 0.82). Patients with virally transmitted diseases had considerable higher costs. The cost per year was substantial. Costs increased with virally transmitted diseases. Number of bleeds and hospitalizations over the period of study decreased and costs increased because of factor use in secondary prophylaxis.
