BACKGROUND: Haemophilia bears substantial humanistic and economic burden on children and their caregivers. Characterising the differential impact of severe versus moderate paediatric haemophilia is important for clinical and health policy decisions. We analysed health-related quality of life (HRQoL), annual direct medical (excluding factor treatment costs), non-medical and societal costs among children and adolescents with moderate and severe haemophilia A or B without inhibitors from the European CHESS-PAEDs study. Information was reported by physicians and caregivers; patients aged ≥ 8 years self-reported their HRQoL. Descriptive statistics summarised demographic and clinical characteristics, costs, and HRQoL scores (EQ-5D-Y). Regression models estimated differences in HRQoL and costs for moderate versus severe haemophilia adjusting for age, body mass index z-score, country, number of comorbidities, and weight-adjusted annual clotting factor consumption. RESULTS: The analytic sample comprised 794 patients with a mean age of 10.5 years; most had haemophilia A (79%) and 58% had severe haemophilia. Mean predicted direct medical costs in moderate patients were two-thirds of the predicted costs for severe disease (€3065 vs. €2047; p < 0.001; N = 794), while societal costs were more than half of the predicted costs for children with severe haemophilia (€6950 vs. €3666; p < 0.001; N = 220). Mean predicted HRQoL scores were 0.74 and 0.69 for moderate and severe disease, respectively (p < 0.05; N = 185). CONCLUSION: Children with haemophilia and their caregivers displayed a significant economic and humanistic burden. While severe patients showed the highest direct medical and societal costs, and worse HRQoL, the burden of moderate haemophilia on its own was substantial and far from negligible.
