Abstract
Purpose: Growth hormone deficiency (GHD) is a rare condition with a worldwide prevalence of 1 patient in 4000 to 10,000 live births, placing a significant economic burden on healthcare systems. The aim of this study is to generate evidence on the economic burden of children and adolescents with GHD treated with rhGH and their parents in Italy. Methods: A cost of illness analysis, adopting the prevalence approach, has been developed, producing evidence on the total annual cost sustained by the Italian National Health System (NHS) and by the society. The study is based on original data collected from a survey conducted among Italian children and adolescents with GHD and their parents. Results: 143 children/adolescents with GHD and their parents participated to the survey, conducted from May to October 2021. Patients had a mean age of 12.2 years (SD: 3.1) and were mostly males (68.5%). The average direct healthcare cost sustained by the NHS was € 8,497.2 per patient/year; adding the out-of-pocket expenses (co-payments and expenses for private healthcare service), the total expense was € 8,568.6. The indirect costs, assessed with the human capital approach, were € 847.9 per patient/year. The total of direct and indirect cost is € 9,345.1 from the NHS perspective, and € 9,416.5 from a social perspective. The total cost incurred by the Italian NHS for children with GHD (range: 5,708–8,354) was estimated in € 48.5–71.0 million, corresponding to 0.04–0.06% of the total Italian public health expense in the year 2020. Conclusions: The total annual cost for GHD children is close to € 10,000, and is mainly due to the cost of rhGH treatment. This cost is almost entirely sustained by the NHS, with negligible out-of-pocket expenses. The economic burden on the Italian NHS for the health care of established GHD children is fourfold higher than the prevalence of the disease in the overall Italian population.
