Once a study is complete, we recommend performing the following actions:

1. Lock all participants
2. Export a copy of the study data 
3. Set the study to 'Not Live' in the 'Settings' tab
4. Remove all users and study admins can reduce their own rights. 
   Delete

   It is recommended that study admins leave themselves as the only user, and remove all user rights except 'View', 'Export' 'Manage Records' and 'Manage Settings'.

   
   

5. Archive the study. Once the study is 'closed', you can archive the study in the 'My studies' overview, which will remove it from the overview for all users and prevent users from accessing it in future. Please note you must have 'Manage Settings' rights to be able to archive or un-archive a study. 

In case medical coding service was used, please make sure to archive any empty coded repeating data instances and inform your Project manager about the study closure, so we could remove the service.
