We have been talking about Precision Medicine for a long time now but so far we are still in the infancy of using genetics to impact medical decision making. The human genome was sequenced in 2003,with the promise of rapid medical advances and genetically tailored treatments. However, development and adoption of these treatments has been slow. Today with the advent of large cohorts, and in particular, the construction of the US Government’s Precision Medicine Cohort,[1] conditions are being set up for precision medicine to flourish. In the PMI infographic,it states three reasons for ‘Why now?’ – sequencing of the human genome, improved technologies for biomedical analysis, and new tools for using large data sets. While I agree this is progress, I believe there area few fundamental other areas to be tackled in order to really get to the promise of precision medicine.
- The concept of protocols is designed for mass production not mass personalization
Medicine is practiced using protocols and documented in EHRs. When written down they can look like a cook book or a choose-your-own-adventure story book. The intent is to codify medical knowledge into a guide that can be consistently used by all physicians to obtain the ideal outcome. But as a result of strict adherence to medical practice standards, they inherently choose paths that are well defined based on the assumption that most people are similar in their response to treatments. So over time the protocol is enhanced to suggest which decision is the right one to make with a given patient and a protocol will more often than not be ‘anti-precision,’ just in the same way that a factory is designed to make one size of jeans at a time rather than make a custom set of jeans for each customer visiting the store.
New data just released on cancer surgery volume in California hospitals advance an important and complex discussion about how the frequency with which a cancer surgery is performed at a hospital might influence patient, care team and hospital decisions. An effort funded by the California HealthCare Foundation has recently made these data available for the first time for 341 California hospitals on
