The Complexities to Creating Real Electronic Health Records

If you have been paying attention (even if you do not live in the United States), you know that the U.S. Congress passed a broad, sweeping piece of legislation, purported to reform health care in the United States. What you probably do not know (even if you do live in the United States) is that this is not the first piece of legislation to target the issue of health care. In fact, a number of pieces of legislation, and a fair amount of money, has been thrown at the issue of health care in the United States in the last few years, specifically in the area of electronic health records. But with all of this focus on streamlining and digitally electrifying health records, I began to wonder where did the Open Source community stand and where is its input? There is certainly a lot of money sitting out there for someone who wants to try to build the better mouse trap.

What got me thinking about this was an article in the Spring 2010 issue of 2600 that reminded me that the issue of record keeping, one of the so called linchpins of reducing a lot of the costs of health care, is not as simple an issue as you might expect. The article cites the break-in and ransom of the Commonwealth of Virginia’s Prescription Monitoring program. This is not the first time I have written about it. But for me, it highlighted one of the many issues that need to be considered when we talk about an eHealth record system. To me, this and a couple of other issues need to be highlighted to better understand the full scope of the problem.

Electronic health records need to be about more than just cost recovery. You could argue that electronic health records are already widely used. And I would not argue with you. I have records in more than my share of medical facilities. But the core purpose of these records is not about patient care, but financial recovery. Nothing made this clearer to me than when I went in for a routine procedure last year. I sat in front of a gentleman who typed in all my important data (name, insurance company, credit card number), made me sign, electronically, a Yes, I will pay form (oh, and a living will) and strapped a human readable and bar code band around my wrist and sent me on my way. While I was lying on the gurney and a procession of medical professionals came by for my physical signature on a ream of paper, each page of which went into a three ring binder, I began to wonder just how automated this all was. The answer, of course, is not very…until the bill arrived.

The health insurance payment process is a cottage industry: a very large, poorly organized cottage industry. In the course of my day job, I had the opportunity to talk with a gentleman from one of the giant heath care insurance agencies in the United States. We started talking about the entire process of processing insurance bills and the complexity of it all. The process is byzantine. A large amount of the physical number crunching is done on what can only be described as legacy systems, with input and output bolted on to them. Old fashioned EDI rules the roost, not XML or similar forms of data transformation, although they are gaining a foothold in some areas. Many of the processes, both input and output, are highly manual, prone to error and as you might expect, expensive.

Electronic health records are not just for hospitals. Like most of you, I have my fair share of doctors that I have to visit on a semi-regular basis, and I seem to add more each year. I have a stable of about eight medical professionals that look after my family including professionals, and of these eight, only one, my ophthalmologist, is completely paperless, except for the actual signature on the charge sheet. The rest have racks and racks and racks of files, filled with inches and feet of medical records. And in most of these offices, there is a dedicated person (or team of people) whose only job is dealing with insurance billing and paperwork but no one is dedicated to the files per se. What this says to me is that any new system has to be easy to use or medical offices will need to hire more people to do less medical work. One thing surprised me, reading the article in 2600. When you are injured and taken to hospital, the EMTs also have to fill in paper and as illustrated by the author, sometimes multiple copies to feed multiple, disparate and disconnected systems, to recover their funds, which means that remote devices will have to be a part of the solution as well.

So if these are some of the issues, and as we look around, are there existing models or solutions that might give us a nudge in one direction or the other? One example of how it could work is the Veterans Hospital Administration VistA system, which has won numerous awards and accolades for technology. The VistA system automates everything from patient care to benefits management to remote prescription dispensing. Doctors can share diagnostic information, images and decisions locally or through consultation across the nation. And the code is Open Source.

But as good as VistA is, it is not the ultimate solution. For starters, the implemented system uses legacy equipment and languages most people no longer program. Further, it is a closed system in terms of who it talks to and who it receives data from, which means data are secure but getting data to and from the system still requires a degree of manual sneakernet processes.

This leads us to another, different set of issues.

How do you get data into and out of the system? And do it securely? I would argue that the banking system probably has a good model, but I cannot speak to it completely or whether it would actually be a good model. Clearly, encryption, shared and public keys, and dedicated pipes would be required. And that infrastructure costs money.

How do you set about equipping, what are essentially mom and pop shops, in the form of the doctors’ offices? And find a way to easily keep the software running and up to date and doing break fix. A whole cottage industry could evolve around this--but with very thin margins. Most doctors offices are run on a shoestring, if they make money at all, so the added expense of hardware, software and the other moving parts that make up the system have to be economical. Makes cloud computing or hosted applications or whatever you want to call it--make sense in certain cases (and yes, I can think of hundreds of reasons why it should not be hosted in the cloud).

Then we have to wrestle with the standards for data interchange. That simple term, data interchange, is loaded with so many complications, permutations, combinations, and issues that the term just is not sufficient to cover the mess that needs to be addressed. And coming up with acceptable standards is going to be a long, tortured process.

In all cases, though, all the roads seem to lead to modernization. No real improvements, in terms of cost savings or speed of processing, will occur without a great deal of modernization. You will not be able to implement some of the necessary standards if the underlying OS is incapable of utilizing them (or the hardware cannot absorb the protocol). I realize it is hard to imagine, in 2010, that there are any systems out there that do not speak TCP/IP, but there are. A staggering number of them fronted by gateways of questionable stability and capability. And of course, any modernization costs money.

And have I mentioned security? In the United States, there is a series of laws, know as Health Insurance Portability and Accountability Act (HIPAA), which defines a number of (sometimes expensive) requirements to protect the data of the individual. These include but are not limited to encryption, access controls, audit controls, authentication controls. Entire monitoring systems could be developed just to ensure that HIPAA requirements are being met.

Is any of this insurmountable? Certainly not, and there are a number of areas where the Open Source community can play a valuable roll. But on reviewing the challenges, I also see why there is not more involvement. Many of the issues require specialized knowledge of a number of aspects of what is today a black box to many. There are few defined requirements and even fewer good directions. But then, is that not what is the best about the Open Source community? We see a problem and try to solve it. Perhaps the right problem has not been presented. Or maybe it is such a niche that I have not seen the strides we have made. But as the big guns of the consulting world are looking at solving this, I hope they will leverage the Open Source model, as well as solutions used elsewhere. And perhaps, just perhaps, a year-five year-from now, we will be talking about Open Source eHealth software the same way we talk about network management software or VoIP software.

Health and safety consultants's picture

You really need to know the ins and outs for these electronic health records. Simply reading the post made my head swirl with complexity. This is very difficult concept to understand for a normal person. However, it is sad that the general public doesn't take keen interest in Health care reforms. They should since it involves stuff about their health care. Than we brag about how we didn't get our share of the insurance and no one informed us that we were covered for less. A self-interest will allow us to know what goes around us and how to actively participate in it to make a change.

Central Records

Anonymous's picture

In some countries (like the Nordic countries, I believe), health records can be held "centrally" in public systems. ("Centrally" to be taken in a semi-central sense of interconnected regional centres.)

Since health issues pertain to everyone (eventually), it would probably be a good idea to keep the data in central repositories, which eliminates any problems with retiring/dying doctors and such. I know this seems a radical approach to most Americans, who have a sincerey mistrust of anything smacking of government, but honestly, are the private companies any better?

The central repositories must adhere to very strict standards of safety and privacy to safeguard the data and the access to the data -- which implies encryption across the board.

Access to the data could be through a web interface and through an API, making it trivial for "mom and pop" shops to get access (HTTPS anyone?) and bigger companies can have their own system programmed to access through the API.

And yes, I know. This says nothing about the solution itself ... Sorry.

There are still more issues

Anonymous's picture

I work in the Medical IT and there are a lot more issues.

1. EHR to PM Billing. (Most doctors are not Billing Coders) and don't know insurance plans and fee schedules.
2. Retiring doctors (You have to keep a legacy EHR system running until the statue of limitations run out?)
3. Medical software (Ever other feature or module just adds to the cost.)
4. Software Licensing, OS and application level.
5. Current staffing computer knowledge. (Why it is bad to surf the net at work?)
6. Billing requirements seem to change yearly. This requires software updates.
7. Most software vendors force you to keep a software contract or they won't talk to you. (SaaS)
8. Same software vendors will sell you hardware only later not support the up keep. (ex. Gladly sell you a windows terminal server with Active directory and all the fixings.) But they are not going to do the updates, add users, or anything else, you need an IT company or person for that. (How does adding 24K to 60K per year cost save you?)
9. In my experience most offices are on a 5 year upgrade cycle. Vendors want you to upgrade your server and software about ever 5 years, dropping another 12K to 25K every 5 years.
10. Hosted services are sometimes making bad quotes that in house IT is not needed anymore. The practice still needs IT services. ex firewalls, PC updates, AV software, etc..

I better stop, this is a complex issue. I could find new stuff almost 10 minutes.

Complexities of EHR

Trying to put a unifying face on the open source community, and get it working on the issue needs a great deal of communication. Luckily, that's what the Internet is for.

Open Source EHRs

Ernst Molitor's picture

Open Source Software offering generic EHRs would be great. For less ambitious targets, solutions are much easier to arrive at. EDP systems are essential for many areas of laboratory medicine; we've been using an Open Source system based on Linux, PostgreSQL, LaTeX, and Apache (PHP) in the field of medical microbiology during the past six years. Linux offers encryption at the file system level, network connections are encrypted (https), and client machines don't need software other than a WWW client (some screenshots are available: http://mibi03.meb.uni-bonn.de/demo/en/ ). Much to our surprise, many clinicians have filed for user accounts and make use of the system - which had been designed for use in the laboratories - to access the results we have for their patients or make use of statistical functions. At any rate, systems like this one have functions other than billing (which is supported, of course) :-)

Best regards,

Ernst

OpenVista

jmdennis's picture

We are going with OpenVista at the hospital I work at but this application does not do most of what we need it to do at our hospital since we also have clinics as well. It also does not take into account billing or registration. The good thing though is that since it is Open Source it can be added to.

VistA and OpenVista

David Lane's picture

From what I understand, OpenVista has some code advantages over its (much) older brother VistA in that it uses C instead of MUMPS for most of the code base and is more modular (we will glaze over the fact that VistA runs on DEC Alphas too).

The parts that are missing are in the imaging suite and the automated prescription dispensing (among others) from what I can recall.

As you pointed out, OpenVista is extensible and that is good, but it is not VistA, which is also good...and bad. But it is one of the few reference implementations of what we could do.

2600 Article

metalx2000's picture

That's my Article in 2600.
It's nice that I helped stir up conversation with an issues I've been trying to get across to some people for a few years now.

As someone in the emergency medical field I see a lot of just crazy things done with personal information. There is a large effort to shred/lock up papers and not to share information verbally. But, I try to get it across to people that leaving that information open on a computer and storing/transferring it unencrypted is the same as leaving the paper work sitting on the counter (actually worse since you can grab thousands of reports in a second).

But, I guess people just don't realize how things work and how easy it is for one person (and one is all it takes) to take and copy that unencrypted information.

Everything you ever need to know about Open-Source Software.

It worked!

David Lane's picture

It certainly struck a chord with me, and as I pointed out it isn't the first time I have addressed this issue, but living in DC, you hear all the Beltway Bandits spewing commercials about how they have the solution when clearly it is a very complicated issue, full of pitfalls and other concerns.
