Heterozygous familial hypercholesterolemia (HeFH) is one of the most common monogenic disorders and is safely treatable with lipid-lowering medication. However, most individuals with HeFH remain untreated and undetected, especially in paediatric populations where the potential for long-term therapeutic benefit is higher. Here, we review the recent literature on health economic outcomes for the detection and management of FH in children.A targeted literature review identified eight studies evaluating detection and management strategies for paediatric FH populations in the last 25 years. Most studies conducted modelled cost-effectiveness analyses to understand the long-term impact of these strategies on health outcomes and the financial impact on the healthcare system. All studies reported that detection and management of HeFH in paediatric populations was cost-effective, regardless of the age of the children. However, cost-effectiveness varied depending on the method of case ascertainment - targeted screening was generally cheaper overall, but less effective, than whole-of-population screening, although both methods were generally cost-effective.Detection and management of HeFH in paediatric populations is a cost-effective way to significantly lower the burden of disease later in life for these individuals. These strategies should be implemented across healthcare systems.
