In a four-level model of the healthcare system, the "middle" typically refers to the "Physician's Office." The structure can often be viewed as a hierarchy or flow, where:
- Patient - at the top, representing the individuals receiving care.
- Physician's Office - in the middle, acting as the intermediary where patients first consult with healthcare providers.
- Physician - can also be considered part of the middle tier since they are the ones providing care and making clinical decisions.
- Hospital - at the level below or alongside the physician's office, representing a higher level of care for more severe health issues or specialized treatments.
This organization emphasizes the role of the physician's office in coordinating care between patients and hospitals. However, the specific structure and functions can vary based on the model used.
