What is the chief pharmacy officer role in health systems?

The CPO role has expanded from drug formulary management to enterprise-level supply chain, 340B program oversight, specialty pharmacy P&L ownership, and biosimilar conversion strategy. Over 60% of large health systems now have a CPO or equivalent, up from 25% in 2018. CPOs typically report to the CMO or CFO and control drug spend budgets of $500M-2B annually.
