Control of who can access your health records depends on who holds them and their format.
You can let the government keep and control access to health records; in which case they determine what records you can view and how you can use them. Unfortunately, government control does not mean others can not access your health records. Here is an example of patient information being sold without your knowledge or permission.
Alternatively, you can control access by taking ownership and possession of your health records.
When you take ownership and possession of your health records, you will need to store them somewhere. You can keep them in paper format (i.e. PDF) or electronic format that makes them searchable and usable.. The people that keep their records in a paper format usually store them in a briefcase or filing cabinet. Others upload a copy of their records to a service like DropBox or Google Drive. When needed, they will share their information by fax or as email attachments.
The Co-op lets you exercise your ownership rights by giving you possession and control of your health information.
