With the increasing importance of data-intensive science, it is becoming more and more likely that you can use existing data for your study. Before you start collecting new data, you should ask yourself whether it is possible to use existing data to answer your research question or to enrich your own dataset.
Reusing data may be more efficient than collecting new data, reducing inconvenience for study subjects and saving resources. In addition, grant reviewers will also take this into account: your chances of getting funded are significantly better if you show that you have considered reusing data. You should also consider re-using metadata from other studies as a template for your own study.
Before reusing data, you should ask yourself the following questions:
Potential sources of reusable data are:
Use the Toolbox to guide you to the data archives, repositories and/or platforms at your UMC.
Yes, personal data from registries can be processed for scientific research purposes, provided that the researchers adhere to the appropriate conditions and safeguards set out in Union or Member State law.
Research results become more reliable if they are based on larger populations and registries may facilitate the collection of data from large populations. By coupling information from registries, researchers can obtain valuable new knowledge about common medical conditions such as cardiovascular disease, cancer and depression.
