CaVa Alpha Release

releases documentation

In which we detail the scope and availability of the CaVa alpha release.


The purpose of the CaVa alpha release is to provide a minimal working example of the data extraction pipeline that has been developed to transform data from the SWSLHD MOSAIQ system. This requires at least one outcome variable (death, unlinked), one exposure variable (drug exposure) and one inclusion variable (diagnosis) in order to produce any meaningful analyses.

In addition, a single variable (ECOG performance status) has been extracted from free-text notes to facilitate a proof-of-concept QA use-case of the platform.


This extract includes all patients created since January 2015.

There is a record in the person table for all unique patients who have at least one diagnosis, clinical note and/or scheduled appointment in the system.
