PHAR investigators, in partnership with BioMarin, conducted a retrospective analysis of two large, national databases (NIS and NASS), finding that in a typical year, around 2,000 people are admitted to US hospitals with a diagnosis of achondroplasia at a cost of approximately $40 million. The average achondroplasia hospital admission is almost $8,000 more expensive and lasts two days longer than the national average admission. The manuscript was published online ahead of print in the Journal of Comparative Effectiveness Research; both the manuscript and the abstract from ISPOR 2021 can be found on PHAR’s publications page.
