REDCap system change announcement on September 7, 2026 - activation of a record limit for projects in development mode.
 
D&D Onderzoek would like to announce the activation of a record limit for REDcap projects that are in Development status. It is planned for 7 September 2026
By introducing this limit, we aim to emphasize that the creation of records during the Development phase should be carefully managed and critically evaluated. The Development status is intended for developing and testing a study database using test data. With this record limit, D&D Research seeks to reduce the risk of unintentionally collecting live data during this testing phase. The limit will be set to five records by default. This can be extended on demand with reasons stated to 10 records.
 
Some development projects may already contain more than five records. These may consist entirely of test data, but they may also include live data. We are unable to verify this ourselves; only the responsible researchers can determine this. In any case, no existing records will be deleted when this limit is introduced. However, it will no longer be possible to create additional records. REDCap will display a clear warning about this in the Record Status Dashboard.
 
To remove the entire record limit, the project must be moved to Production status as soon as possible, either with or without retaining the data that has already been collected. A user with setup rights can initiate this process by clicking “Move Project to Production” in the Project Setup page. Cleaning up test data and live data can take place either before or after submitting the Move Project to Production request. However, when submitting the request, it must be clearly indicated that the data should be retained if live data has already been collected. If this is not explicitly specified, all data—which we must in principle regard as test data—will be permanently deleted.
We appreciate your understanding and hope that this measurement will contribute positively to improving data collection practices in REDCap. If you have any questions or comments, please do not hesitate to contact us. You can reach us by email at imo-servicedesk@umcg.nl

Instructions for users from connected UMC's
Existing REDCap users from connected UMC's can log in using the SURFconext button. If you work at a connected UMC and are new to REDCap, and you need access to a project in REDCap UMCG, first log in via SURFconext. Your REDCap account will be created automatically upon your first login. Afterward, please inform the project's Principal Investigator (PI) at UMCG that you require access. The PI can then request access for you through the UMCG Research Self-Service Portal (umcg.topdesk.net). For questions or assistance with REDCap login, please contact the IMO Service Desk at imo-servicedesk@umcg.nl.

Applications Overview A brief exploration of four popular built-in features for project or data management: 1) User Rights, 2) Data Import Tool, 3) Data Exports, Reports, and Stats page, and 4) Alerts & Notifications.

The Calendar This tool organizes your study by tracking upcoming milestones and events.
7 minutes
Scheduling Module This is an optional feature in longitudinal projects. The tool generates record-specific schedules based on a series of events or timepoints. Used with the calendar module, this tool greatly streamlines longitudinal data entry.
7 minutes
Data Access Groups
for multi-site projects 		The Data Access Groups feature assigns users to groups. Any user in a Data Access Group may only access their group's records. Each group is blinded to all other data/records. Users not in a group can access all data across all groups. This feature is especially useful for multi-site projects because each data collection site must usually be restricted from viewing other sites' records.

Types of REDCap Projects
There are several flavors of REDCap projects to choose from as you begin thinking about building your own project. Each type of project has its advantages and disadvantages, and may fit the specific needs better of one type of project over another. Please review the different types below, and you may even view a live example of each project type in action or view a short video about it.

Types of Projects This video describes two major decisions that must be made when building a REDCap project. It also briefly illustrates how these decisions affect which type of project is used.
3 minutes
Traditional Project
(classic model with data entry forms)
 The traditional project is used for basic data collection. All data is entered directly in REDCap by users who log in. Multiple data collection instruments are often defined. This project type is suitable for most data collection needs. It can capture longitudinal data, including adverse event reporting or other collection that does not have a pre-defined schedule or end-point.
3 minutes
Single Survey Project The Survey module allows a REDCap instrument to be completed by survey respondents who do not log in. Data can also still be entered by REDCap users (who do log in). This video explores all the major features of the survey module, including survey distribution. A single survey project has only one data collection instrument, which is used as a survey.
5 minutes
Longitudinal Project
(multi-use data entry forms,
abstract time-points)
 The Longitudinal module allows any data collection instrument(s) to be completed multiple times for each record. The same data may be captured repeatedly. The module uses an event grid to define clear timepoints used for data collection. The longitudinal module is best suited to very structured studies which do NOT last indefinitely. Clinical trials frequently use this project type.
3 minutes
Longitudinal Project
+ Scheduling
(multi-use data entry forms,
defined time points)
 This project type uses two modules. The Longitudinal module allows any data collection instrument(s) to be completed multiple times for each record. The Scheduling module adds record-specific schedules onto a study calendar, using the longitudinal event grid. Schedules can be generated and modified. The longitudinal module is best suited to very structured studies which do NOT last indefinitely. So this project type is useful for large, multi-site clinical trials needing a quick and easy way to schedule patient visits.
3 minutes
Operations
(use case for non-study/non-trial)
 REDCap can be used for almost any type of data collection. The most common uses are clinical research and trials. However, REDCap is also suitable for administrative and educational data, workflow tracking, quality improvement, biobanking, registries, and non-human research. This example explores a traditional project type being used to capture and track operational bookkeeping information.

Special Features within REDCap Projects
Every REDCap project is capable of utilizing special features, some of which can be enabled by normal users and some by REDCap administrators. Below is a listing of these features.

Feature Description Watch
Video
Defining Events in Longitudinal Projects Defining events is a requirement of the Longitudinal module. That module allows any data collection instrument(s) to be completed multiple times for each record. The module uses an event grid to define the timepoints used for data collection. This video illustrates how to define the timepoints (also called events).
5 minutes
Designating Instruments for Events in Longitudinal Projects Designating instruments is an optional step of the Longitudinal module. That module allows any data collection instrument(s) to be completed multiple times for each record. The module uses an event grid to define the timepoints used for data collection. This video illustrates how to designate which instruments are completed at each timepoint.
3 minutes
Repeating instruments and events In-depth overview of how to set up and utilize the Repeating Instruments and Repeating Events functionality in both classic and longitudinal projects.
33 minutes
REDCap Mobile App The REDCap Mobile App is an app that can be downloaded onto a tablet or mobile device to allow REDCap data to be collected locally on that device without the need for an internet connection (either wifi or cellular signal). If a user downloads the app, they must explicitly be given mobile app privileges in a given REDCap project in order to set up the project on the app. Once a project has been set up on the app, data can be collected in an offline fashion and then later synced back to the REDCap server.
2 minutes
Locking Records The locking feature freezes data. Users can still view existing data, but they cannot modify it unless they have the needed User Rights permissions. This video illustrates the basics of how instruments are locked. Refer to the built-in help resources and locking applications for more detailed instructions about locking management.
