[Import/Export](https://support.enrollnow.io/en/knowledge-base/import-export?hsLang=en) June 18, 2026 # Importing Data: Global vs. Study-Specific Data EnrollNow allows users to upload two types of data: **Global Data** and **Study-Specific Data**. Understanding the difference ensures accurate data management across studies. ### **Global Data** Global data includes participant information that is not tied to a specific study. It remains consistent across all studies and is visible in the Global Registry. ***Examples of Global Data:*** - **Participant Identifiers** (e.g., name, date of birth, address) - **Global Custom Variables** (marked as "global" during setup) - **Contact details** - **Demographic information** **Key Features:**  - Follows participants across all studies they are enrolled in. - Visible in the Global Registry for comprehensive participant tracking. - Can be used across multiple studies without duplication ### **Study-Specific Data** Study-specific data is unique to a particular study and does not transfer between studies or appear in the Global Registry. ***Examples of Study-Specific Data:*** - **CustomID** (unique participant identifier for a specific study) - **Event Dates** (e.g., visit dates, follow-up schedules) - **Study Statuses** (e.g., enrolled, withdrawn, completed) - **Recruitment Sources, Sites, and Strategies** ### **Choosing Between Global and Study-Specific Data** | **Feature** | **Global Data** | **Study-Specific Data** | | --- | --- | --- | | **Visible in Global Registry?** | ✅ Yes | ❌ No | | **Follows Participants Across Studies?** | ✅ Yes | ❌ No | | **Examples** | Name, DOB, Address, Global Custom Variables | CustomID, Event Dates, Status, Recruitment Details | | **Customizable Per Study?** | ❌ No | ✅ Yes | By correctly designating **Global vs. Study-Specific Data**, EnrollNow users can efficiently manage participant information while maintaining data accuracy and study-specific integrity. ### **When Should I Upload Global Data?** Global data should be uploaded **directly into the Registry** when: - You are importing a large database of participants who may later be assigned to different studies. - You have participants not yet enrolled in a study but may be recruited in the future. - You want participant information, such as names, contact details, and global custom variables, to be accessible across multiple studies. ***Example Use Case:*** - You have a database of 5,000 potential participants and want to add them to EnrollNow before assigning them to specific studies later. - Uploading this list directly into theRegistry ensures that they are available for future study recruitment without duplicating participant records. ![](https://support.enrollnow.io/hs-fs/hubfs/Knowledge%20Base%20Import/support.ripplescience.comhcarticle_attachments4783179248141.png?width=548&height=396&name=support.ripplescience.comhcarticle_attachments4783179248141.png) ### **When Should I Upload Study-Specific Data?** Study-specific data should be uploaded directly into a study when: - You are importing participants directly into an active study. - You need to include study-specific details such as: - - Recruitment source, site, or strategy - Event data (e.g., visit dates, milestones) - Study-specific participant identifiers (CustomID, statuses, etc.) - You want participants to appear in the Registry, but their study-specific details will only be accessible within that study. ***Example Use Case:*** - You are conducting a clinical study and want to import participants with their study-specific recruitment source, assigned site, and enrollment status. - Uploading directly into the study ensures their study-related details remain separate from general participant information in the Registry. ![](https://support.enrollnow.io/hs-fs/hubfs/Knowledge%20Base%20Import/support.ripplescience.comhcarticle_attachments4783187149453.png?width=534&height=386&name=support.ripplescience.comhcarticle_attachments4783187149453.png) **KEY CONSIDERATIONS**: - **All study-imported participants** will also be available in the **Registry**. - **Study-specific event data and custom variables** (unless marked asglobal) will not be visible in the Registry. - **Still unsure?** Contact EnrollNow’s support team at help@enrollnow.io for guidance on thebest data migration strategy for your needs.   -
