This paper discusses the public health implications of antimicrobial drug regulation and the need for incentives to conserve antibiotics at various levels. It examines the challenges faced by hospitals, physicians, patients, and drug companies in conserving antibiotics and proposes strategies to improve antibiotic markets. The authors emphasize the importance of new molecule production, stewardship, infection control, and systemic antibacterial drug approvals in addressing antibiotic resistance. The paper also explores financing mechanisms and proposes value-based reimbursement contingent upon meeting global conservation and health targets.

Coordination Abx = common pool resource No real global coordination on new production or use (withdrawals) Hospitals, physicians, patients, payors, drug companies & drug sellers all lack financial incentives to conserve See R.

Conservation Commercial incentives undermine conservation Poor incentives at patient, provider & industry levels Complex delivery, cultural & infrastructure issues, esp. globally Kesselheim AS, Outterson K, 11 YJHPLE 2011
Production New molecules are needed, else class and sector exhaustion Stewardship and infection control diminish market incentives Declining returns to R&D observed Kesselheim AS, Outterson K, 11 YJHPLE 2011

Proposal 1 Value-based rbx for social value of abx Financing mechanism is OECD health system rbx Contingent on meeting global conservation & health targets Scalable globally Contingent P4P Kesselheim AS & Outterson K, Improving Antibiotic Markets, 11 YJHPLE (2011); Kesselheim AS & Outterson K, Health Affairs Sept. 8, 2010.
Current metric: Ability to pay With de-linkage: Cost of resistant infections? Cost of current ID burden? Cost of avoided infections? Room for adjustment if SV>PV by an order of magnitude Contingent P4P
Social Value of the ABX gap In billions of US Dollars at various DALY value levels. Underlying data on burden of disease from WHO 2008. Estimates by Outterson (2009)
Further Issues OECD willingness to rbx Setting & measuring realistic global conservation targets Industry capture Top down bias Voluntary contracts with companies (no change to IP rules)
Strategic ABX Reserve Proposal 2 • $$ for conservation, not use • Voluntary, science-driven • Significant $$ demonstration • Complete de-linkage for 1-2 especially valuable molecules Kesselheim AS & Outterson K, Improving Antibiotic Markets,11 YJHPLE (2011); Kesselheim AS, Outterson K, Health Affairs 2010; 29(9):1689-96; Love J, Prizes, not patents, to stimulate antibiotic R&D, SciDev.Net (26 March 2008); So AS, et al.
