What is meant by the "opt out" method of health information exchange?

The "opt out" method of health information exchange refers to a system in which patients are automatically included in health information sharing initiatives unless they specifically make a request to exclude themselves. This approach facilitates broader data sharing among healthcare providers, which can enhance care coordination and improve patient outcomes. It allows for the efficient flow of information while still providing patients with the autonomy to control their personal health data by requiring them to actively express a desire to opt out if they do not wish to participate.

In this context, patients are informed that their data will be shared by default but have the option to refuse this sharing. This approach is in contrast to models where explicit consent is required for each instance of information sharing, promoting a more streamlined process for healthcare providers.
