Assessing Physician Influence on Pharmaceutical Adoption

This technical report examines the impact of physician relationships on the adoption rates of pharmaceutical products, specifically focusing on the influence of physician networks on treatment patterns. The study analyzes Medicare claims data to assess whether connections among healthcare providers (HCPs) affect the uptake of a novel therapy, referred to as Product N, for treating wet age-related macular degeneration (wAMD). The findings indicate that HCPs connected through networks exhibit significantly higher adoption rates for Product N compared to those who are not connected. The report outlines the methodologies used to define and analyze these networks, including shared patient claims and healthcare organization affiliations. It also discusses the implications for pharmaceutical manufacturers in targeting early adopters within physician networks to enhance product dissemination. The research highlights the necessity of understanding both geographic and social connections among physicians to effectively influence drug adoption and improve patient care.
