BACKGROUND: Pay for performance (P4P) schemes provide financial incentives or facilities to health workers based on the achievement of predetermined performance goals. Various P4P programs have been implemented around the world. There is a question of which model is suitable for p4p implementation to achieve better results. The purpose of this study is to compare pay for performance models in different countries. METHODS: This is a descriptive-comparative study comparing the P4P model in selected countries in 2022. Data for each country are collected from reliable databases and are tabulated to compare their payment models. the standard framework of the P4P model is used for data analysis. RESULTS: we used the standard P4P model framework to compare pay for performance programs in the primary care sector of selected countries because this framework can demonstrate all the necessary features of payment programs, including performance domains and measures, basis for reward or penalty, nature of the reward or penalty, and data reporting. The results of this study show that although the principles of P4P are almost similar in the selected countries, the biggest difference is in the definition of performance domains and measures. CONCLUSIONS: Designing an effective P4P program is very complex, and its success depends on a variety of factors, from the socioeconomic and cultural context and the healthcare goals of governments to the personal characteristics of the healthcare provider. considering these factors and the general framework of the features of P4P programs are critical to the success of the p4p design and implementation.
