The most common models, and their basic payment composition, are listed below. For instance, Family Health Organizations (blended capitation, FFS and P4P) and Family Health Groups (blended FFS and P4P) account for about 55% of primary care physicians (Table 2.4). Additionally, some incentives are paid periodically (e.g., once a year) while others are paid every time a specific service is provided. Eligibility for some incentives is patient-based (i.e., the physician receives a payment for having provided a specific service to an individual patient), while for other incentives, eligibility is based on performance across all registered patients practice-wide (i.e., the physician receives a payment for having reached a pre-defined target level based on a number of services, a number of patients or a percentage of eligible patients who received the service).
