Which is a type of HMO where health care services are provided to subscribers by physicians employed by the HMO?

The staff model is a specific type of Health Maintenance Organization (HMO) in which healthcare services are delivered directly to subscribers by physicians who are employed by the HMO itself. This structure allows for greater control over the services provided, as the HMO has direct oversight of the healthcare professionals within its network.

In staff model HMOs, the physicians typically work in the HMO's facilities, and patients usually access care exclusively through this network of employed providers. This arrangement can foster a more coordinated approach to patient care, as physicians are part of a cohesive organization with shared goals and protocols.

The other models mentioned differ in the way they organize healthcare delivery. For example, a group model involves a network of independent physicians providing care through contracted arrangements, rather than being employed directly by the HMO. An exclusive provider organization (EPO) often allows for more flexibility in provider selection than a staff model, but it does not employ the healthcare providers directly. A preferred provider organization (PPO) operates similarly to an EPO but typically allows members to see out-of-network providers at a higher cost, emphasizing flexibility rather than employed staff.

Thus, understanding the distinct characteristics of the staff model helps clarify its role within the broader landscape of health insurance delivery systems
