Longitudinal projects allow for the collection of data over time with the ability to track changes and progress. Longitudinal instruments eliminate the need to recreate multiple of the same forms, where instead the form is created once and assigned to multiple time points within a project. Some useful situations for longitudinal projects include:

• Long term studies

• Clinical trials

• Recruitment and enrollment combinations

• Multi-site studies

• Repeating surveys (medications, lab results, adverse events forms)
