Electronic Health Records and the challenge of Unstructured Data

The real problem of an established medical practice moving into the realm of EHR is not the cost of the medical software package; it is not the training necessary for staff; and it is not security and backups.

The real problem of moving into EMR/EHR is the problem of unstructured medical data.

If you are involved in a new or relatively new practice, this is a no-brainer. Begin with a serious search to compare medical software vendors who are available to answer your questions honestly. It is not truly so difficult to get on a friendly medical screen to enter your patient’s blood pressure or lab test values. You can get used to that.

Neither is it difficult to take notes on a notebook that upload to the EHR system.

The real problem is taking your notes and dictation on a patient that go back 15 years and finding a way to get his possible symptoms, his worry about IBS, his headache history, and his worries over his children into a metrically available rendition that that does not take you or a member of your practices days to decipher. These notes are usually on dictation, hand written notes, and referral letters.

The concerns are many: this can take what feels to be forever, and the anxiety issues and unclear symptoms may not translate easily into metrics but may be critically important in future diagnoses.

There are two critical questions here:

  1. 1) Is it worth it? and
    2) If it is worth it, what to do to make this work efficiently?

In the long run, it doesn’t even matter if it is worth it. It will happen. Medicine as well as the rest of our cultural world, is becoming electronically-based whether we like it or not. But in the long run, it is worth it. Think of a patient going in to the hospital after a car accident, all by himself, and having all his data available to the admitting doctor in an instant: blood type, history, etc.

Think of a patient being referred to you, the specialist, and having all his patient history available in less than a minute. What a time saver! What insight!

Medical informatics has a number of methodologies it is using to translate unstructured data into useful and structured data.

Three basic methodologies exist to accomplish this:

  • String matching
  • Natural language processing for Medicine (NLP), which uses syntactic rules in extracting data from text documents
  • Concept-based indexing which uses data base codes to group and relate medical concepts

These methods will be refined, utilized, and integrated in some way into most decent medical vendor software packages over the next few years. For you the physician or practice manager, this may start to pay off in a while, but you still have to get from hand written records into the database.

The obvious way to proceed makes use of our culture idea of, “going forward”:

  1. Start with today’s records being input into the database electronically – this is the easy part.
  2. Then get help in moving 1 year of back data scanned and automated. Get someone technically savvy and talk to the support people whose EHR software you are considering about OCR (optical character recognition) software that may be available from vendors.
  3. Most vendors of decent repute will have voice recognition software incorporated into their total EHR solutions. Have them demonstrate how well it works in moving data into their files.

The real message to practitioners moving to electronic health records is, don’t look at the top of the mountain when you start climbing, just put one foot in front of the other. Delaying the climb will not get you anywhere, but starting the march will move faster than you think!

Don’t let Poor Planning Make the Migration to EMR/EHR More Difficult

Filed Under EMR Software, Medical Software | Leave a Comment

Having recently spent time as an observer in a hospital setting, I was struck by the lack of intelligent planning and forethought made for doctors trying to move into an EMR / EHR environment.

Though I saw a well-known EHR panel on the computer screens within an ICU, and the EHR being used to record certain patient data, doctors were taking their notes in long-hand. Later on the same day I saw the same doctors transcribing their notes onto their computers. The doctors, doing double duty on note taking were not available to their patients because they were acting as secretaries.

When a large clinical environment is incorporating an EHR it has to be done in a modular way that does not impact productivity any more than it has to. The task is hard enough. If you are using an EHR to record point of care patient information, give your doctors a Notebook so they can take their notes electronically. In fact, insist on electronic note-taking. Incorporate change with some forethought to peoples’ time and effort.

This real-life observation just underscores the need to plan for transition to an EMR rather than throwing an institution into the chaos of change for its own sake, or for the sake of Meaningful Use incentive payments. As in all things, the old US Coast Guard motto holds true: Semper Paratus! Always be ready and prepared.

Most good EMR / EHR systems can offer medical clients some guidance as to best practices in incorporating EMR / EHR systems within their practices.
