EHR Privacy Debate Heats Up

Posted by Soulskill on Mon Jan 19, 2009 08:15 AM
from the doctored-files dept.
CurtMonash writes "The New York Times reports on President-Elect Obama's continued commitment to electronic health records (EHRs), which on the whole are a great idea. The article cites a number of legislative initiatives to deal with the privacy risks of EHRs. That's where things start to go astray. The proposals seem to focus on simply controlling the flow of information, but from a defense-in-depth standpoint, that's not enough. Medical care is full of information waivers, much like EULAs, only with your health at stake. What's more, any information control regime has to have exceptions for medical emergencies — but where legitimate emergencies are routine, socially-engineered fake emergencies can blast security to smithereens. So medical information privacy will never be adequate unless there are strong usage-control rules as well, in areas such as discrimination, marketing, or tabloid-press publication. I've provided some ideas as to how and why that could work well."

    I saw this [case.edu] the other day. Basically, a pair of professors, one in law and another in computer science (specializing in software testing) are trying to bring the problems with EHR to a wider audience.

    They call for testing and certification of EHR systems (Though thankfully not through the FDA).

    It'll be interesting whether anyone listens to them.

    One of the problems with EHR is that it potentially follows you your entire life.

    If information about your economic status, familiar situation, physical location, customs, etc. Usually becomes unreliable after some time. A leak on those informations slowly loses effect.

    Medical information, however, is permanent in many cases. A single leak of a person's data can have fresh information for, literally, a lifetime.

    This has been in place in many other countries for years, including the UK where - for all the bureaucracy and wastage of the NPfIT [wikipedia.org] initiative - it's been largely successful.

    The system isn't perfect, and human error is the main source of problems and breaches (as ever), but the benefits have so vastly outweighed the risks that I'm surprised this is even being debated.

    Most importantly, all the problems envisaged by critics have already been anticipated, encountered and (largely) overcome in other countries. Take a look outside your borders and learn a few things. Find out what works and what doesn't, and use the mistakes of others to build a better system. Just don't start panicking over nothing. This is not a pioneering initiative, in global terms.

    Essentially what you need is DRM. The data is only available on a limited number of machines and then strictly limited in what you can do with it, with strong audit trails. Not using general purpose computers but rather devices might help.

    But in the end I don't think this is likely to work, the incentives for hacking are too strong and the distribution has to be too wide. EHRs mean that there will be substantially less medical privacy in exchange for better medical care and lower costs (70b-300b / year). That doesn't seem like a bad trade.

It would likely help you and your primary care doc carefully review what you should be doing in your life, although the conversation likely would be on the order of "get more exercise, eat something healthy occasionally, quit smoking" that we can do quite nicely without your gene sequences. However, you don't want insurance companies to get a hold of it.

It sits on it's input queue until done then sits in its output queue. Then it gets sent to an HL7 routing engine where it sits on queues. Then on to our medical database. This generates some billing info which goes to the HL7 router then on to a private company in Tennessee, which sends results to a website....

        Now I'm sure there will be controls on who can get at the medical database. But what about the data whizzing around the network? Tell me about the audit trail that lets me know who saw some of the info generated by that one encounter. Because it sat on at least 7 machines in 3 states for some amount of time.

        And now you want each of those machines to check to see if the patient has signed off on that machine getting the info? Good luck with that.

        And if someone shows up unresponsive in the ER, how do we send the X-ray to the remote radiologist if the patient can't release the data? And if 'emergencies' override that control, expect to see EVERY encounter be an emergency.
