Each participant retains control over their own data, which can be accessed securely by authorized users when needed. This approach allows for local autonomy while still facilitating the exchange of health information.

Centralized Architecture

In a centralized architecture, health records are consolidated into a single system maintained by a central entity. This approach provides a centralized repository of patient information, making it easier to manage and exchange data. However, there may be concerns regarding data security and privacy in this model.

Hybrid Architecture

The hybrid architecture combines elements of both federated and centralized models. It allows for the storage of health records in both regional and centralized databases. This approach aims to strike a balance between local control and centralized access to health information.

Data exchange in HIE relies on two primary methods:

1. Push Exchange: In push exchanges, data is sent from one participant to another without a specific request. This method is commonly used for sharing lab results, medication lists, and care summaries. It ensures that the receiving provider has access to up-to-date patient information for informed decision-making.
2. Pull Exchange: In pull exchanges, a provider queries a participant or HIE system to retrieve specific patient information. This method is often used during unplanned care situations, such as emergency room visits. It allows providers to access essential health information, such as allergies, previous treatments, and diagnostic reports, to support timely and accurate care decisions.

HIE facilitates the exchange of various types of data, including:
