Subject attributes

You can select from a range of subject profile attributes to identify subjects in your study. Subject profile attributes marked as mandatory are required to be filled in before the subject can be submitted/enrolled to a site. You can choose optional attributes if wanted.  

Tip: Send questionnaires to your subjects via email or SMS, by selecting either:

  • Email as a mandatory subject attribute for sending questionnaires via email only.
  • Email and Phone Number as mandatory subject attributes for sending questionnaires via both email and SMS.

Subject ID

There are four variants of subject ID available in Greenlight Guru Clinical. Three automatic IDs, where the system will assign IDs upon enrolment or manual subject ID, where the user enrolling the subject will give them a subject ID.

The three automatic types of IDs are:

  • Study incremented ID
    A study-wide counter that starts at 001, and counts up with every new subject enrolled in the study, regardless of the site they are enrolled to.
  • Site ID & study incremented ID
    The id is a combination of the site ID and a study-wide incrementing number, starting at 001.
    Assume there are two sites in the study: London with the site ID LON and Copenhagen with the site ID CPH.
    The first subject is enrolled to London, so they get the ID: LON-001
    The second subject is enrolled to Copenhagen, so they get the ID CPH-002

  •  Site ID & site incremented ID
    Using this automation, each site has its own incrementing number along with a site ID.
    Assume there are two sites in the study: London with the site ID LON and Copenhagen with the site ID CPH.
    The first subject in the study is enrolled to London, so they get the ID: LON-001
    The second subject in the study is enrolled to London, so they get the ID LON-002
    The third subject in the study is enrolled to Copenhagen, so they get the ID CPH-001

The manual type of ID

  • Manually entered subject ID
    This type of ID can be applied if a study wants to customise the subject-ID. It will, however, require that the study personnel type in the subject ID of interest each time a new subject is enrolled to a site.

You cannot change between automatic subject ID's once the study has been started and a subject enrolled, nor can you remove subject ID as an attribute.

Verification is a tool that allows monitors, sponsors, or data managers to mark data as verified. The verification tool can be given any meaning desired by the study, as it can be named when setting up the study. Examples could be: Monitored, Source Data Verification (SDV), or reviewed. Depending on what is needed in the study. For more details, please go to our Verification article.

When creating a study or editing an already existing study, you can add up to two verification types. These work exactly the same way, but make it possible to differentiate between the two verification groups, due to the two colors. This can be useful when study personnel with different roles in the study has to verify the data independent of each other. Each verification type has their own permission. To manage the permission(s) go to add collaborators, under site permissions the two verification types will be visible.

Time and date format

You can specify the date format on a study level, which will determine how dates are displayed in the study. There is a list to choose from: EU, ISO, and US formats with different lengths, and different delimiters.

Extended Validation
