Technical situation


In this page we review the proximate technology situation. 

Technology has been a key driver of consumer interest in health care since the 1940s.  Significant current developments are reviewed.
Health Information Technology policy is discussed. 


Heath care markets are deeply affected by technology developments and constraints.  Since the 1940s deployment of penicillin Americans have been convinced that their health issues have technological solutions.  The health care VDS has formed around this view, supporting and leveraging it. 

Expected technological advances, some discussed by NIH is the National Institute of Health, Bethesda Maryland.  It is the primary federal agency for the support and conduct of biomedical and behavioral research.  It is also one of the four US special containment units of the CDC.   director Francis Collins, suggest major transformations & powerful justification of health care:

  • Epidemiology studies patterns, causes and effects of health and disease in populations.  It identifies risk factors for disease and focuses on preventative health care.  Being observational it suffers from a core limitation.  It can only show association, not causation.  It can suggest hypothesis but it can not disprove them.

  • Distributed ledgers: bitcoin is a set of open-source software, used to provide infrastructure that supports a distributed cryptocurrency and payment system, based on the blockchain.   All transaction inputs are unspent outputs from previous transactions.  All transaction inputs are signed.  Change is provided in an additional output to the transaction. 
    's blockchain is a bitcoin distributed database technology that allows several bitcoin operators to keep a shared, cryptographically verified, ledger and consensus mechanism to allow agreement on what transactions have happened and in what order.  It implements a Merkle tree.  Six times an hour on average, a new group of validated transactions, a block, is created, added to the local block chain and published to all nodes.  Paraphrasing breadwallet's Aaron Voisine, publishing is robust because: Each operator has connected via references from its initial peers to a random subset of all the other operators; and the new block is offered to the connected peers who can both ask for it if they have not seen it previously from some other source and pass it on to their other peers in a cascade (a gossip network).  To build new blocks an operator must have all the prior blocks in the chain.  All unspent bitcoins are represented [only] in the blockchain.  Miners keep the blockchain consistent by verifying that a new block has a proof-of-work.  This requires that miners find a nonce that multiplied by the block hash is smaller than the network's difficulty target.   (Oct 2016)
