Abstract

Introduction: Patients suffering from von Willebrand disease (VWD) have a variety of bleeding symptoms and require both outpatient care for treatment and, in more severe cases, hospitalization. Aim: To investigate the impact of having VWD on frequency of hospitalization compared to a control group and to evaluate whether regular replacement therapy (prophylaxis) is associated with reduction in the number of hospitalizations. Methods: Linkage of national population-based registries was used in the Congenital Bleeding Disorders study in Sweden (CBDS). Data were from the von Willebrand Disease Prophylaxis Network (VWD PN). Results: The national registries contained 2790 subjects with a diagnosis of VWD between 1987 and 2009. A total of 13 920 age- and gender-matched controls were identified. There were 2.0 times (range 1.5-2.5) as many inpatient hospitalizations among subjects with VWD compared to controls. The most common causes of hospitalization were gastrointestinal (GI) bleeding (n = 232 as primary diagnosis), menorrhagia (n = 198) and epistaxis (n = 192). Outpatient visits per year were also twice as common among those with VWD. From the VWD PN, 105 subjects were included (VWD type 3, 52.4%; type2A, 22.9%; type 1, 12.4% and other types, 3.9%). A total of 122 hospitalizations due to bleeding episodes, dominated by GI bleeds, were analysed. Significantly fewer hospitalizations occurred after initiation of prophylaxis (75 prior to and 45 after, P = .006). Conclusion: Our study indicates that subjects with VWD have a considerably higher consumption of healthcare resources compared to controls and that initiation of prophylaxis may reduce the number of hospitalizations due to bleeding.
