• 38 percent of patients with depression do not respond to the first drug they are prescribed
• 40 percent of patients with asthma do not respond to the most commonly prescribed drugs
• type 2 diabetes (43 percent), arthritis (50 percent), and Alzheimer’s disease (70 percent) do not respond to the most commonly prescribed drugs
ORY chromosome (From Father) and Mito-
chondrial (From Mother) are used for
identification process.

The study drew on electronic health records of 16,234 patients admitted to intensive care units—including medical, surgical, and cardiac units—at Boston's Beth Israel Deaconess Medical Center from 2001 to 2007. Researchers created an algorithm that combines 27 factors into a Targeted Real-time Early Warning Score, or TREWScore, measuring the risk of septic shock.

Evolution of the concept
Precision Medicine
• Clinicians have always practiced personalized medicine, using personal health information to make decisions on diagnosis and treatment.
• When we refer to personal health information we are including genetic, physiological, anatomical, environmental risk factors, socio economic issues, cultural and psychological aspects as well as the familial and individual health history.

President Obama Announces the Precision Medicine Initiative
Precision Medicine: Defined and Compared
Personalized medicine:Collect and analyze extensive information and data
about patient, EHR to genome and beyond; physician
uses this information and data to make more informed
diagnosis and treatment plan
Current medical practice:Use vital signs today relative to last visit (EHR?); assess
symptoms; physician uses expert background, experience
and judgment to diagnose, prescribe
Precision medicine:Use massive data network that aggregates and analyzes
information from huge patient cohorts, healthy
populations, experimental organisms– and reaches toward
disease mechanisms, and precision diagnosis and
treatment for each individual
