Abstract
Millions of patients are affected by adverse drug reactions (ADRs) every year. It represents a substantial burden on healthcare resources. Pharmacovigilance using text and data analytics has drawn substantial attention in the recent years. These techniques are mainly extracting the associations between drugs and ADRs using data sources such as spontaneous reporting systems, electronic health records, medical literature, and pharmacological databases. In this work, we are not only interested in extracting the associations between drugs and ADRs but also the associations between diseases and ADRs. There is an association between a disease and an ADR when the drugs treating the disease are associated with the same ADR, which means there might be an underlying mechanism-of-action (MOA) between the disease and the ADR [1]. The ADR can be considered as a clinical phenotypic biomarker for the disease. In addition, we are adopting the social media data as the data source in analytics. The social media provides timely and large volume of health consumer contributed information that overcomes the limitations the traditional data sources. We propose to construct a heterogeneous healthcare network from social media data and develop three path-mining techniques to the clinical phenotypic information. The experiments results demonstrate that the proposed method is effective in detecting significant and novel ADR-disease associations. Case study shows that many of the association can be supported by existing academic literatures.
