A professional arrangement exists where services are offered to a specific, pre-defined population. This model restricts access to its resources, usually based on affiliation with a particular organization, insurance plan, or geographic location. For example, a medical clinic exclusively serving employees of a specific company operates under this structure.
This framework often provides predictable patient volume and revenue streams, fostering opportunities for specialization and enhanced quality of care within the defined population. Historically, these models arose to streamline service delivery and manage costs within closed systems, such as large corporations or governmental agencies. Efficiency gains and improved coordination of care are potential advantages.
