The process of adding and managing countries and regions

A region refers to a geographic area that contains one or more countries. Countries are the individual countries in which sites are located. Regions contain countries, which contain sites. For example, sites might be located in Brazil, Argentina, and Uruguay. Those countries exist in the region of South America.

Before you can add sites to a study, you must first add the countries and regions where those sites are located.

During study setup, you do the following:

Add countries to a study, and assign a region to the country.
Edit or delete as necessary.

If a depot or drug destruction facility (DDF) is located in a region that contains no sites, you must still add that region to the study to allow the depot or DDF to be active in that region.
If a depot or drug destruction facility (DDF) is located in a country that contains no sites, you must still add that country to the study to allow the depot or DDF to be active in that country.
If the randomization schedule uses a country as a region, you must have a randomization schedule for each new country you add. Otherwise, you cannot randomize at sites from that country.
