Technical Symposium

Confounding in Datasets

Date: Monday 29 August
Time: 1:00-4:30 pm
Venue: Hotel Realm, Canberra

There is global interest in using computerised databases for comparative effectiveness and medication safety studies. However, the data represents patients in practice. Patient and physician characteristics may affect the likelihood of receiving treatments. This creates the potential problem of confounding, which must be overcome to obtain robust results from observational studies.

The technical symposium will explore the issue of confounding in Australian and international datasets.

The methods to deal with confounding in observational studies will be presented including: propensity scores; instrumental variables and the self-controlled case-series design.

Specific examples will be presented to highlight how researchers can apply these techniques to evaluate the risks and benefits of medicines.
