abstract
Due to the risks involved in not achieving desired health outcomes for the dollar spent on drugs, healthcare decision makers, including payers, providers, drug manufacturers, and patients, need a mechanism to share this financial risk among the involved parties. Performance-based risk-sharing arrangements (PBRSAs) are agreements that can potentially reduce the 'drug lag' in which patients wait for an unknown amount of time until a particular drug is covered under their health plan. In addition, PBRSAs can mitigate the risk of investing heavily in drugs that are ineffective or do not deliver good value or "bang for the buck". This review describes and evaluates PBRSAs for drugs in the USA and juxtaposes to other developed nations (i.e. Germany) that adopted PBRSAs in their healthcare model. There are different types of outcomes-based health schemes, namely conditional coverage, which can be further broken down into coverage with evidence development (CED), conditional treatment continuation (CTC), and performance-linked reimbursement, which includes outcomes guarantees. Both CED and CTC are 'conditional' on the collected evidence of the new drug's effectiveness, offering discount only if the drug delivers desirable results. The outcomes guarantee scheme offers discount or even a full refund if the outcome is less than expected, forcing the drug to meet the expected effectiveness. The USA can follow the German reference pricing model in which the assessment of new drugs is centralized and done collectively by representatives from a group of healthcare decision makers. In any shape or form, PBRSA is a clever mechanism to cope with uncertainty if drug price is scaled appropriately based on value.
