The Promise

"Personalized medicine is coming of age," writes Bill Frist, the former US Senate majority leader and a former surgeon, at The Hill's Congress Blog. Frist (R-Tenn.) notes that more tailored medicine should lead to disease prevention and earlier diagnosis as well as to better treatment. Additionally, he says that such an approach should save money as dollars would no longer be spent on treatments for diseases that can be prevented, and on drugs that won't work. "Increasingly we will see individual genome sequences become a formal entry in our medical records, just like allergies and history of previous surgeries," Frist writes. "As information technology in healthcare matures, we will see more connectivity among providers and labs, more support to eliminate costly and deadly medical errors, more automation to reduce the chances of making bad mistakes, and more data mining that will lead to science-based predictions of how to reverse disease and prevent it in the first place."
