Adverse Event Detection
An adverse event (AE) is any untoward medical occurrence with a patient or clinical investigation subject who has been administered
a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. The objective of
pharmacovigilance is to deal with identifying hazards from pharma products and minimizing risk to patients. Companies need to have
such a process to assess compliance to global laws, guidance and regulation.
Typically, a patient or physician reports an adverse event through a phone call or letters. This is an obligation imposed on pharma
companies to provide the channels for reporting, record the cases, investigate and show the outcome of the investigation. People are
increasingly using social media to provide their feedback and talk about drugs or devices in case of adverse side effects.
Social Media Surveillance
About the
solution
Wipro’s Adverse Event detection ‘app’ is a solution that crawls social media such as Facebook,
Twitter etc. as well as special forums where people discuss about the treatments. This is done to
identify sentiments towards a drug or device and segmented by demographical dimension to
see if an adverse event is present. An obligatory Adverse Event is noted only when following
information is present: an identifiable patient, an identifiable reporter, specific drug or biologic
involved in the event, an adverse event or fatal outcome. It also records perceptions towards
competitors’ products.
Detection of Adverse Events
The app incorporates text processing and standardization for transformation of free form text on
social media. It also leverages an event detection algorithm based on modified KMP [Please
expand the term] algorithm to look for a word or string with collocation parameterization and
sentiment analysis to determine the underlying intent of their comments on social media
websites. It provides demographic segmentation based on consensus and reports on any
potential adverse event being talked about in social media.
Business Contextualization
It helps in determining the safety, effectiveness, and prevalent sentiment towards your own
product as evident from the general concord of public sentiments and presence of adverse events.
