Welcome. The aim of this decision tree is to help you decide whether or not your study is research. It is based on the Defining Research leaflet produced by the Health Research Authority (HRA).
You will be presented with a short series of YES or NO questions. Take your time to consider the wording carefully. Once you have answered these questions the tool will let you know if your study is research.
To help you with terminology, a GLOSSARY button is available on every page. All links to individual glossary items or other websites appear in purple text and open in a new window.
Post Market Surveillance is NOT usually considered research. However, there are some circumstances where an NHS REC approval may be required. See HRA guidance. Return to the Do I need NHS REC approval? tool to determine if your post market surveillance requires NHS REC approval.
