Include information on the variables that you intend to use to define your cohort of interest. Please be as precise as possible. 

The CRIS Extraction Team have a role in facilitating extraction of variables from CRIS and will advise on how best to extract robust data. The information submitted in this application will be used to provide a basis for the data extraction specification. The data contained within CRIS is complex and users will be encouraged to collaborate and share expertise and hands-on experience.

Where variables are required that must be compiled manually by reviewing free text fields (e.g., case note entries or letters within the medical record), you will be required to complete a free text security review. The CRIS Extraction Team will support you with completion of this after the project is approved. A similar procedure will be followed where the project is focused on text reviewing to create a Natural Language Processing (NLP) algorithm/ application. 

NOTE: Applications to use staff names for legitimate research/ audit purposes may be granted but additional mitigation may be put in place, e.g., encryption of staff names in CRIS extractions.
