  • Amazon, AI and Medical Records: Do the Benefits Outweigh the Risks? - Knowledge Wharton

    Last month, Amazon unveiled a service based on AI and machine-learning technology that could comb through patient medical records and extract valuable insights. It was seen as a game changer that could alleviate the administrative burden of doctors, introduce new treatments, empower patients and potentially lower health care costs. But it also carries risks to patient data privacy that calls for appropriate regulation, according to Wharton and other experts.

    Branded Comprehend Medical, the Amazon Web Services offering aims “to understand and analyze the information that is often trapped in free-form, unstructured medical text, such as hospital admission notes or patient medical histories.” Essentially, it is a natural language processing service that pores through medical text for insights into disease conditions, medications and treatment outcomes from patient notes and other electronic health records.

    The new service is Amazon’s latest foray into the health care sector. In June, the company paid $1 billion to buy online pharmacy PillPack, a Boston-based startup that specializes in packing monthly supplies of medicines to chronically ill patients. In January, Amazon teamed up with Berkshire Hathaway and JPMorgan Chase to form a health care alliance that aims to lower costs and improve the quality of medical care for their employees.

    “Health care, like everything else, is becoming more of an information-based industry, and data is the gold standard — and Amazon knows as well as anyone how to handle and analyze data,” said Robert Field, Wharton lecturer in health care management who is also professor of health management and policy at Drexel University. “It’s a $3.5 trillion industry and 18% of our economy, so who wouldn’t want a piece of that?”

    AI offers “enormous” promise when it comes to bringing in new and improved treatments for patient conditions, such as in the area of radiology, added Hempstead. Machine learning also potentially enables the continual improvement of treatment models, such as identifying people who could participate in clinical trials. Moreover, Amazon’s service could “empower a consumer to be more in charge of their own health and maybe be more active consumer of medical services that might be beneficial to their health,” she said.

    On the flip side, it also could enable insurers to refuse to enroll patients that they might see as too risky, Hempstead said. Insurers are already accessing medical data and using technology in pricing their products for specific markets, and the Amazon service might make it easier for them to have access to such data, she noted.

  • What Tasers Do to the Brain
    http://nymag.com/scienceofus/2016/02/what-tasers-do-to-the-brain.html

    Tasers aren’t known to be the gentlest things, to put it mildly. The devices deliver 50,000 volts of electroshock, and though deaths after use of electroshock weapons — #Taser is the brand name — are relatively rare, in 2015, at least 48 people died during interactions with police who used Tasers. Now, a team of scientists at Drexel University and Arizona State University set out to investigate — what are Tasers doing to the brain?

    Their results, published recently in the journal Criminology & Public Policy, suggest that the electroshock can impair a person’s cognitive functioning for up to an hour after being Tased, which “questions the ability of … suspects to waive their Miranda rights knowingly, intelligently, and voluntarily within 60 minutes of a Taser exposure,” the authors write.
