A local skilled nursing facility (SNF), hospital, and public health agency all participate in an HIE. The data is pushed from their facilities into one repository where they all have access to retrieve data when needed. Which HIE model is used in this scenario?

In this scenario, the correct model is centralized HIE. In a centralized model, data from various healthcare facilities, such as skilled nursing facilities, hospitals, and public health agencies, is aggregated into a single repository. This allows all participating entities to access a common pool of data when needed, streamlining information sharing and enhancing care coordination.

The centralized approach provides a unified view of patient information and can improve efficiency and consistency in accessing care data. It also simplifies the architecture of data exchange, as all data is housed in one location rather than being distributed across multiple systems. This model facilitates easier management of data security and privacy policies, as the central repository can be controlled more tightly compared to more distributed approaches.

In contrast, the other models (distributed, federated, and decentralized) involve different mechanisms for data sharing, where data may be kept at individual facilities without a central repository, leading to varied access protocols and potentially more complexity in data exchange.
