Abstract

BACKGROUND: There is limited evidence on within-country discrepancies in biosimilar uptake. This study analyzes differences in timing and diffusion of biosimilar uptake across Portuguese NHS hospitals and explores possible determinants. ***RESEARCH DESIGN AND METHODS: We analyzed publicly accessible consumption data of originator biologic and biosimilar drugs for adalimumab, etanercept, infliximab, rituximab, and trastuzumab, by hospital and month for the years 2015–2021 (N = 9,467). We modeled the time to biosimilar adoption using survival regression models and the share of biosimilar consumption using generalized estimated equations with random hospital effects. ***RESULTS: Academic hospitals were characterized by a quicker uptake of adalimumab and infliximab biosimilars but lower shares for other drugs. A higher total consumption of biologics was related to a lower share of biosimilar uptake. A stronger participation in randomized controlled trials was linked to higher biosimilar shares and quicker uptake, except for rituximab. If all NHS hospitals had biosimilar shares equal to the highest ones, potential annual savings could reach 13.9 million euros.
