History
DxEM started over thirty years ago when NASA began planning trips to the moon and Mars. This was the time when 2001: A Space Odyssey by Stanley Kubrick was still fresh in everybody’s mind (1968). A grant proposal was submitted by the College of Medicine at the University of Florida (UF) to NASA Kennedy Space Center for the construction of medical HAL, the paranoid computer in the Kubrick film. Nobody thought it could be done but they were willing to let UF try. For twenty years a team of physicians, programmers and textbook specialists worked to produce HAL, and it actually succeeded. This was long before the Internet and Google. At that time, the UF team was working with mainframe computers and rudimentary word processors. By the late 1990’s the project was ready to be tested in space with astronauts. Then something happened that changed its future. The NASA manned missions were cancelled, and robots and remote vehicles were introduced. The 20-year multimillion-dollar project was disbanded and all the material, staff, and programs were terminated. A great deal was learned in this twenty-year period about how to make computers medically intelligent and empower them to think and reason with sound medical logic. This core knowledge has now been incorporated into a new company called KQI, Knowledge-Quest Inc. (KQI).
One major spinoff of this early NASA experiment is KQI’s design of its medical databases. The UF staff learned early that computers can’t “reason” or comprehend medical textbooks and complex English text construction. Computers need data organized and logically constructed as modules and factoids that can be assembled into a complex search engine. The best way to do this is to construct a relational database of medical facts. All symptoms need to be identified individually for every condition and sorted separately. All lab tests need to be separated and linked to symptoms and diseases. All words need to be searchable and able to be sorted by multiple criteria. All references need to be attached to individual facts and separated from each other. Facts need to be given qualifiers like frequency of occurrence and clues on how they should be interpreted.
To make this new database possible you need a whole new structure and a new authoring tool that can enforce editing and authoring uniformity. This new authoring system needs to have quality control features and programs to check spelling and content integrity. It also has to be automated so that the data collection process is highly efficient. This tool was constructed and now powers DxEM.
If you can create the database, the next task is to build an application that makes it useful. That program exists, and it is called DxEM.
DxEM operates in two forms: the editing version and the production version. What you see as a user of the application is the production version. What authors see is the editing version. We have an automated program that takes our editing database and populates our production system. This conversion process takes less than 30 seconds. This rapid updating means that we can republish our entire production database as often as needed without any additional expense. No paper, no shipping, no delay. With each update you get the most current snapshot of all aspects of medical diagnostics. Instead of months or years of delay, current knowledge and wisdom can transfer instantaneously and be there when you need it.
Beyond the original goal of creating an intelligent assistant to astronauts, part of our charge was to build an intelligent electronic medical record system (EMR) that could travel into space and oversee astronaut day-to-day healthcare. We actually did this using available technology. At that time there were no cell phones, no laptops, and no Internet. Our early solution required mainframe computer support and was not able to transition into space. We did build this intelligent EMR and it was highly successful. With the termination of the NASA project our EMR needed to find a new home. It was eventually sold by UF to a nationally known medical computer company.
To update this story, DxEM has now been installed in a new intelligent medical record system for primary care and small hospital applications. Our testing and validation process of this new system has shown that we can save up to 60% of physician data entry time in routine charting. In addition, the clinical support information in DxEM can be delivered within the medical record so that physicians get current data at every stage of their critical order and planning process. We can now demonstrate a closed system from knowledge creation to knowledge delivery that can be reduced from months and years down to days and hours. By breaking the barrier on knowledge transmission and directly reaching the patient care frontier, we can truly see a revolution in healthcare delivery that goes way beyond continuing medical education. In industry they use a term called JIT (just-in-time). Stores scan product codes at checkout so that the JIT delivery system can have stock on the shelves when you arrive. In medicine, we use POC (point-of-care) to describe technology that is at the patient’s bedside for immediate application. DxEM’s EMR provides JIT knowledge delivery at the POC. This is a quantum leap that uses computer speed and accuracy for the patient’s immediate benefit.
The Author
Dr. Ralph Grams was the author and project manager of the original NASA research grant from the College of Medicine at the University of Florida (UF). He was Professor of Pathology and Director of the Medical Systems Division for most of his career. He retired in 2015 after 42 years at the University of Florida College of Medicine. He now devotes full time to KQI so that this technology can become commercially available. He is the sole author and editor of this vast array of medical data and has used modern technology to amplify his authoring speed so that a large professional staff is not required. The continuity and cohesion of all the software design and database changes have come by testing and validating each step of the process. Multiple versions of this database have been tested until an ultimate design was reached. In addition, multiple program changes have occurred over the years until we have our current cloud-based platform. The focus has been on distilling the best clinical data into the shortest packets of knowledge that can be clinically useful. This is not a book but a database of highly structured medical facts. Every fact has multiple references to support its authenticity. No personal biases or editorial comments are allowed. Everything must be traceable to its parent sources. This system must stand the legal test of authenticity and the ability to defend its output based on sound clinical logic which physicians can support and duplicate.
Questions:
- How accurate is the database? Answer: It is as accurate as the authors of the Gold-Standard textbooks and journals. Our job is to translate their expertise into a relational database structure so that it is computable.
- How deep does our database go and what is its range of coverage? Answer: Our database addresses every field of medicine from surgery to psychiatry. This includes: diseases, drugs, toxins, chemicals, animals, plants, bioterrorism agents, and environmental hazards. Anything that can make a human sick. We cover: anatomy; pathophysiology; clinical descriptions; age, sex, and race preferences. For all our symptoms and clinical tests we also attach an interpretive comment on how that finding should be applied in the clinical setting. In many cases, we show how to do the procedure and what it means. This could be a picture or a video. In pathology and radiology, we provide links that show a positive result that marks the diagnostic highlights. In pathology, we have links to slides and micrographs that are used for interpretation.
- Does the database cover treatment? Answer: Yes and no. Where there is a clear singular treatment available we will list that drug or procedure. If there are multiple treatment options, we provide links to other sites that have those treatment options explained.
- Why not add more people? Answer: The automated editing system can easily handle dozens of additional medical editors. This additional expense can’t be currently supported without additional revenue.
- Why is your system unique? Answer: DxEM is totally transparent. It has no secret artificial intelligence program that analyzes data. Everything in our system mimics the doctor’s reasoning process and could be duplicated by any clinician who is willing to spend the time to read and organize the information. We use Boolean algebra and set theory in our symptom/test checker program and that is totally visible in our application. You can drive the program yourself and make any changes you want in real time. This is truly a diagnostic video game that has a serious outcome for someone with a medical problem.
- Why not make it free? Answer: Programming, editing, and the internet processing is not free. These are basics that must be covered to keep the process going. We have positioned our access fees to be consistent with major clinical textbooks. Our service provides monthly updates to the database which no textbook can duplicate. New items are coming in daily and you will have them as soon as we can validate their content and see it properly loaded into the files. We also offer discounted prices to students and those who have groups that would like to have a multiuser license. These prices and arrangements can be made by contacting our corporate email address.
- What can your intelligent EMR do that current systems can’t? Answer: Since we know all the signs and symptoms for over 11,000 diseases and also all the useful laboratory tests that can be done to define each condition, we can prepare patient medical records very rapidly once we have a working diagnosis. This means minimal keyboard activity and rapid customization of the record to the patient. We also link our system to the doctor’s cell phone and can seamlessly transfer cell phone data to the exact location needed in the patient chart. Any cell phone attachment like a retinal camera can transmit its data directly into our EMR. This eliminates office filing and post visit charting activity. We also have over 8000 links to medical images, charts, graphs, pictures and videos that help teach and explain every disease or condition we reference. This can be used for patient education as well as physician continuing medical education.
- What additional features does your system provide? Answer: Our system has a comprehensive medical dictionary that is derived from the database and all the new data being entered. It knows current terms and names before a paper dictionary gets them in print. We also have a comprehensive testing library that tells you about each test and critical information about how it is done and what are normal results. These also contain links to tables, graphs, charts and videos that show you how the process works.
- How does DxEM compare to Google or Bing? Answer: These major search engines are keyword driven. You get content surrounded and filled with advertising. You also get millions of hits which you have to filter to find anything worthwhile. They can’t do symptom/test analysis since they do not have a relational database. We tested the Google model over thirty years ago and that is why we built a medical relational database to drive our applications. We also do not allow any advertising on our system so you don’t get popups and annoying interruptions.
- Can a consumer use this system? Answer: Yes. The keyword search option allows you to use any term you know and it should find the medical term that applies. We have a large expanding synonym file that converts common spoken language into medical terminology. Most families have someone they know who is working in the medical field. This can be a great resource to help with a more complex symptom analysis. With your user name and password, they can access your subscription and guide your medical investigation. You, as a patient, can look up any disease or condition and see the full range of symptoms and tests that are used in that disease process. This can help you monitor your condition and support your disease education. We also have links to pictures, tables, graphs, animation and videos to add to your educational experience. Hours have been spent selecting these graphics so you get quality information with little delay. If you have a serious disease, you must educate yourself as soon as possible and become your own advocate. This means learning some medical terms and understanding how your disease operates. The more you know the better you will be able to select doctors and treatment plans that make sense for your situation. Our tool is designed to empower the consumer to be informed and proactive. If you don’t care about your healthcare delivery then you will likely be just another statistic. The current healthcare system is overloaded and you must defend yourself and those in your family. DxEM will give you the information you will need to be proactive and informed.
- What is offered to professionals? Answer: Our symptom/test analyzer has many advanced features which clinicians will find helpful. Everything can be downloaded to another system or printed. We have special graphics programs that allow you to compare different diseases with tables that you create. These can be used for charting or educational lectures. We also have analysis programs that give you a score for the best fit for your patient’s symptoms and tests. The convenience of having a diagnostic digital library on your phone or laptop 24/7 is a great resource in complex situations.
- What serious problems does this database/library address?
- Answer: In 2015, the National Academy of Medicine’s report was published: “Improving Diagnosis in Health Care”. It concluded that getting an accurate diagnosis was one of the key factors missing in our current healthcare delivery system. If the primary diagnosis is wrong then everything that follows will be wrong. The Academy was seeking ways to make an improvement in this problem and we have offered our solution. This finding was also supported by reviewing medical malpractice litigation data which supports “failure to diagnose” as a key factor in medical malpractice claims. DxEM intelligent EMR directly addresses these issues by allow a working diagnosis to be followed and analyzed for accuracy. We offer questions to ask and tests to do to confirm that primary diagnosis. We also provide extensive alternates to a primary diagnosis that shows diseases that could be confused with your primary diagnosis (differential diagnosis). DxEM also has a list of secondary diseases that can occur if you have a primary disease. These secondary diseases could be complicating the treatment given for the primary disease process.
- Answer: Today, our medical knowledge is turning over and changing at an incredible speed. Who can keep track of what is going on? Who can memorize all this new information and still have time to practice medicine? That is why healthcare providers need a constant flow of new updated information that reaches directly into their day-to-day activities. With our continuing editing of quality medical knowledge and the electronic publishing of this data directly to the provider, we break the cycle of darkness that surrounds those on the front lines of medicine. We can provide a two-minute synopsis of any disease or condition and cover all the relevant clinical facts in this short period of time. This is critical in the high intensity environment in which most physicians operate. These memory joggers are a rapid form of continuing medical education that fits our frenetic healthcare delivery system.
- What can we expect in the future for DxEM? Answer: With our current and projected critical healthcare manpower shortage, there will not be enough doctors and nurses trained to care for our aging population. This manpower shortage exists around the globe. We are going to need digital support tools that consumers can use at home to care for themselves. The database we have built will someday power a medical avatar that can assist with day-to-day personal needs and help guide specialty care and treatment. This will operate like Lexa or Siri but will have all your personal medical information with which to reason. This will be your personal avatar and not shared with others. It will operate to keep you healthy and informed of your medical status just like your car has a reporting system that comes to your phone. This personalized support could greatly reduce the cost and demand on our hospitals and clinics and offer cheaper options to deal with long-term care and follow-up.
