RESUMEN
BACKGROUND: Despite the growing interest in risk-sharing agreements as appropriate payment mechanisms for high-cost treatments, few practical resources facilitate their adoption. OBJECTIVE: To identify and propose lessons for designing and implementing these models based on a review of the international experience, and to offer a concise model based on these lessons. METHODS: The steps of the Joanna Briggs Institute were adopted, which included identifying the concept and its relevant variants in scientific and gray literature. RESULTS: Forty-one references were examined in depth. The design of these payment mechanisms should be a process carried out by competent actors (payer, producer, specialists, patients, and a neutral entity); the design must be supported by a sound regulatory and contractual framework that structures its components and clarifies the functions of each actor. Finally, there are critical activities for each actor in each phase of the agreement's progress. CONCLUSIONS: The participation of all actors and the clarification of critical elements and tasks are fundamental for the optimal development of the experiences.
