Social Media
• With the advance of Web 2.0 technologies, the Web is not only a resource that patients look for health information but also a virtual community where patients interact with each other to provide different kinds of social support and exchange information where they may not be able to obtain from local health professionals.
“e-patients are looking for ‘just-in-time someone-like-me” health information”

Drug Safety Signal Detection
• Adverse drug reactions (ADRs) are causing a substantial amount of hospital admissions and deaths – 5.3% of hospital admission were
associated with ADRs
– 7% of medical errors were attributed to ADRs
• Pre-marketing review process cannot possibly identify all potential adverse effects.
• Post-marketing surveillance programs must be conducted to identify new adverse effects and evaluate their potential impact on the public health

Drug-Drug Interaction Detection
• Drug-drug interactions (DDIs)
– a significant drug safety problem for health consumers
– may account for up to 30% of unexpected adverse drug reactions
– often caused by shared pathways of metabolism or interesting pathways of drug action
– DDIs detection is of great clinical importance because most interactions could result in precaution of prescription, absolute contraindications of combination use, or even drug withdrawal from market
