Alongside PHAR’s first virtual exhibit presence at Virtual ISPOR 2021, PHAR investigators presented their findings outlining the national burden of achondroplasia in adults and children, done in conjunction with BioMarin Pharmaceutical. Their examination of the National Inpatient Sample, the largest all-payer inpatient healthcare database in the US, provided the first national estimate of the cost or burden of hospitalization and surgery in adults and children with achondroplasia. They estimated that the annual cost of hospitalization alone was $40 million. The iPoster can be viewed here, and the abstract was published in the May 2021 supplement issue of Value in Health.
