A fascinating and slightly cynical overview of Silicon Valley’s ideological view of health tech that will fix our ‘deeply flawed healthcare system’ and what is getting funded (or not) is in next month’s San Francisco magazine. It profiles the ‘citizen doctor’ founders of vital signs ‘tricorder’ Scanadu (Sam–who’s not often mentioned–and Walter De Brouwer), bacteria tracker uBiome, ‘personal data recorder’ and experience charter We Are Curious (founded by Linda Avey, a long-departed co-founder of 23andme) and touches on the Theranos debacle. While these stories are bracing and in the instance of the De Brouwers, courageous, the notion of ‘citizen science’ (defined as direct-to-consumer health data) and its companion, Dr Eric Topol’s patient-centered/controlled medicine, has its drawbacks, viewed through the slightly gimlety ‘digital doctor’ eye of UC San Francisco’s Dr Robert Wachter. “The overarching message—not just from Theranos but from other companies struggling to get a toehold—is that, ultimately, the laws of economic gravity hold. The companies will have to produce products that add real value, either to patients or to payers. If they don’t, the market—or the regulators—won’t treat them kindly.” Flatly, there aren’t enough Quantified Selfers right now to support these companies. And Mr Market is a hard master. 23andme is back in the good graces of the FDA after a two-year scuffle and back doing direct response TV here in the US. Scanadu’s two products, Vitals (formerly Scout) and Urine are still not through the long slog of FDA clearance. The jury’s out on Theranos. And all these companies, including ‘unicorn’ Theranos, are bleeding cash and nowhere near turning a profit. ModernLuxury. Hat tip to Dr Topol via Twitter, who had a patient-centered conversation with Dr Wachter that we covered back in September.  Another recent podcast with Dr Wachter is here (Community Health Center radio).

Update: ‘Citizen science’ is nothing new, as revealed by the Science Museum (London)–it’s over 300 years old. While it entered the OED in 2014, ‘in 1715, Edmund Halley used Philosophical Transactions to ask colleagues to help him observe a total solar eclipse, prompting observers from all over the country to respond.’ Other examples are from Benjamin Robins in the same publication in 1749 on fireworks, Charles Darwin and evolution, to the present day. The difference is the flow–similar to what we now call crowdsourcing versus the individual using the data to affect their care.
