The Nature of GSSA Data
- Consumer-derived data
- GSSA's focus is complaints containing adverse events
- It's standardized and codified according to MedDRA
- It offers a unique lens with which to view consumers' feedback on our products
- It allows us to perform signal detection and identify specific issues with our products
- GSSA data provides multiple data views such as historical, global and regional views to support new/similar product launches globally or regionally
- GSSA data offers many possibilities for the application of Data Science and Data Mining techniques
