CAS Explorer

Overview:

The CAS Explorer was an online interactive tool that showed the completeness of data fields within the Cancer Analysis Service (CAS) database from 1995-2016. The database was held in the National Cancer Registration and Analysis Service (NCRAS) part of NHS England (formerly Public Health England). It helped researchers to better understand the data on cancer held by NHS England. 

Further details:

The CAS database held up to 1,000 data items for each cancer patient, including information on demographics, tumour staging, treatments and hospital use. The CAS Explorer, developed by HDI, showed the completeness of the CAS database, and was designed to be used by researchers and analysts to check the data quality of the table fields before requesting data through the Data Access Release Service.  Researchers used the CAS explorer to find out which data fields are included in the Simulacrum dataset – a synthetic dataset developed by Health Data Insight that mimics some of the CAS data.
