Temporal data mining of patient-specific notes stored in electronic patient record (EPR) systems can be used for pharmacovigilance in a clinical, multi-diseased and polypharmacy population.

Structured and unstructured data accumulated in the EPRs permits dose-specific monitoring of adverse drug reactions (ADRs) and observations of patients affected by ADRs in the actual clinical setting.

High throughput analysis of the data already collected in EPRs by healthcare providers can be used to verify suspected correlations, as well as suggest novel likely correlations between drugs and adverse events.
