We Should Implement Genetic Testing For Everyone and Rebuild the Medical System Around It
Medicine could be revolutionized if
- All patients were genetically sequenced
- All medical outcomes were tracked in tandem with patient's genes with millions of observations
- Privacy Regulations were weakened to allow for this mass tracking of outcomes and the training of machine learning algorithms to generate novel insights at lower and lower costs
- Clinical Practice was restructured to take into account the ever increasing amount of information about how genetics affected the odds of a diagnosis and likely treatment response and this became a standard tool in personalizing and guiding treatment
This would not happen overnight if everyone's genes were sequenced but it would provide the necessary backbone to revolutionize medicine as more and more data was generated and clinicians were trained or retrained to incorporate these insights into how they practice. We could imagine that the ideal anti-depressant for a patient could be selected after treatment response was compared to the genetics of the many millions of patients on each type of anti-depressant.
The advantages of improved health outcomes for patients would outweigh the privacy concerns stemming from the generation of a such a dataset. The world is already transparent the use of grades, BMI, credit card spending and existing medical information, and online activity would be sufficient already to build an Orwellian surveillance state if anyone really wanted to. Genetic data is not going to change the picture much and fears are overblown
Implementing this system would require a lot of work and stepping on the toes of patients, providers, and health insurance companies who would all have their own reasons for not wanting to embrace it but it is no longer impractical to do with significant investment and regulatory easing from the government.
When adjusting for labor costs, the cost of sequencing a whole genome at high fidelity is about $500 (the raw cost is closer to $200 and a cheaper targeted genetic screen could be implemented for much less), and this only needs to be performed once. Likely, this cost would go down by a factor of two after some upfront investment in the government and the gradual improvement of sequencing machinery. In contrast a Colonoscopy costs about $1000 and will be performed ~3-5 times per lifetime. The cost of generating high quality raw genetic data is not a limiting factor in medicine, the lack of interest, expertise or infrastructure to interpret the data into clinical decisions is and this a problem that could be overcome.
