Computer technology in medicine: the history of communication, value and prospects. Part I

It's no secret that computer technology has penetrated almost all aspects of modern society: politics, defense, entertainment, education, and much more. Medicine is no exception. Now it is not a secret, but 60 years ago it all seemed like science fiction.

Today we will touch on the past, present and future partnerships of these very different industries, medicine and computer technology. We will find out what revolutionary discoveries have been made, what shortcomings and dangers this partnership carries in it and, finally, what future of medicine awaits us.

The use of computer technology in medicine

At the moment, computers have become widespread in many branches of medicine. Starting from the CPOE (computerized physician order entry) - a computerized physician prescription system (prescribing tests and / or medicines), ending with robots interns that help surgeons during surgeries. Also, computers play no small importance in the work of clinics as a whole, helping to plan and carry out various administrative tasks, keep track of finances, conduct inventories, etc.



The Internet has also played a minor role. Thanks to him, a new direction in medical diagnostics appeared - teleradiology (in other words, transmission of images and data of a medical nature through the World Wide Web). This innovation made it possible to analyze the patient's data and make decisions regarding his treatment while being away from him, thereby saving valuable time. Also, doctors were able to quickly consult with their colleagues from around the world. A huge database of medical knowledge stored on the Internet is available to patients, giving them the opportunity to get acquainted with their disease, recognize symptoms, find out the necessary information about the doctor and / or clinic, about drugs, etc. Regarding the use of the Internet patient goes quite a bit of controversy. The fact, that trusting the patient himself to diagnose himself and prescribe treatment is extremely dangerous for him. On the other hand, if a patient combines the use of information from the Internet with a visit to a real doctor, this can improve the quality of his treatment.



And perhaps the most unusual use of computer technology in medicine is video games. They are used to train surgeons who will later perform laparoscopic operations (when small cuts are made in the area of ​​the operation for the operation inside, instead of a large incision and an “open” operation). Studies in 2004 showed that surgeons playing video games about 3 hours a week make 37% fewer errors during such operations.

Electronic Medical Records (EMR)

Back in 1960, an article was published in the New York Times newspaper in which one doctor from the University of Tulane expressed an interesting thought about "medical records stored on film, or in another computer-friendly way that can completely crowd out written records of patients." In 1967, another article mentioned the following vision of the future - “every man, woman, or child can have all of their medical data electronically recorded in a huge memory system in Washington.” Let's discuss the benefits of such a system. If, for example, a person has a heart attack, and he is in another city. The article responded: “It will be enough for the prescribed doctor to call to Washington, and after a second before him there will be all the data from this patient.” Now, more than half a century later,



In addition to the advantage of remote data access, EMR has others that will be discussed later. Based on these advantages and the fact that the idea of ​​electronic records has been around for many decades, you might think that EMRs are used absolutely everywhere. However, this is not quite true. For example, in the US, EMR is used only in 17% of clinics.

EMR history

In the late 1960s, a programming language called the Multi-Programming Multi-Programming System (MUMPS) Massachusetts General Hospital Utility Multi-Programming System was developed for use in healthcare systems. It did not become widespread until the 1970s, when it began to be used to create many clinical programs. To this day, many old systems work with software based on MUMPS. Despite its initially medical direction, MUMPS is widely used in other industries that require a large number of simultaneous connections to the database (banks, stock exchanges, travel agencies).


In 1978, Joseph (Ted) O'Neill and Marty Johnson, together with their team, developed Fileman using the MUMPS language. Fileman was a set of generalized procedures, specially simplified for users who do not understand MUMPS and programming in general. From the late 1970s to the early 80s, many utilities were designed on the basis of Fileman. Later, the US Department of Veterans Affairs began using Fileman as its official medical program.

In 1981, in Florida, Mickey Singer founded a software company called Personalized Programming Inc., which was one of many that later formed Medical Manager Inc. It provided clinics and private practitioners with software, the popularity of which was so great that by 1997 more than 24,000 clinics and 110,000 practitioners used it. However, only a fall followed. In exchange for Medical Manager Inc. came the Open Public Public License (GPL), providing its users with the source code of the software, giving them the opportunity to carry out the necessary customization.

Currently, the number of companies providing solutions for EMR varies from 250 to 500. Some of them focus on small systems, such as prescription or case history. Others offer package solutions.

Benefits of EMR

The main users of EMR are doctors and other medical personnel. Standard EMR gives them access to the electronic version of the patient's medical history, which had been stored on paper for many years. So why change something that worked so long?

• The answer is simple - doctors' mistakes. One of the main problems of medicine in all eras was the iatorogenic complications of the patient’s condition, that is, those that were unintentionally caused by the actions of honey. the staff. For example, the appointment of the wrong drug or the appointment of too large or small dose. Electronic medical records in conjunction with clinical decision support systems can provide automatic checks to prevent such errors.
  
• Another advantage already mentioned in this article is access to the database from anywhere in the world. This allows you to better coordinate the work of various specialists, reducing the time taken to review the history and decision making. And time, as we know, is very often a critical factor in the struggle for the life and health of a patient.
  
• To facilitate the work of doctors and reduce the time it takes the patient to visit them, coordination of EMR with other systems, such as laboratory, is also necessary. Previously, the patient came to the doctor, he prescribed certain tests / tests for him, the patient went to the laboratory, transferred the appointment, did the tests and the results were recorded on paper again and should have been transferred to the doctor. This is a long process, during which errors and confusion are not uncommon. Let's start with the classics - the doctor's handwriting may be illegible, the wrong tests may be performed, the results may be lost or confused. If we use the interrelation of two electronic systems, then the direction and the results will be placed in the electronic folder of the patient, which has access to a doctor.
  

• This ill-fated medical handwriting carries many problems in the process of extracting drugs. A pharmacist may incorrectly read either the name or the dosage of the medicine, and this, as you understand, can have terrible consequences. Electronic recipe system eliminates the possibility of such a "misunderstanding".
  
• It is also important convenience for patients, because they do not need to ring up all the clinics that they visited to collect the necessary medical history. All of it is stored in the patient's folder.
  
• Electronic records of patients can (and should) be backed up, etc. make backups. With paper notes, this is difficult, and, in truth, no one did. For example, after Hurricane Katrina, thousands of patient histories were lost, and their recovery took many months.
  
• The more common the EMR will be in the world, the easier it will be for researchers. A huge database of patients, their symptoms and diseases, methods of treatment and the process of recovery - all this will help to study certain diseases, improving methods of dealing with them.
• In the long run, the use of EMR is cost effective. There is no need to spend money on the office (this is a trifle, but on a global scale, the sums will be large), a reduction in the number of staff, a reduction in time and, accordingly, an increase in labor efficiency.
  

Disadvantages of EMR

Despite the very impressive advantages of EMR, their speed of distribution is not impressive. Now we consider why.

• Many modern EMRs are incompatible. The fact is that each clinic has its own base, which does not work with the base of other clinics. As it is not profitable to facilitate the process of the patient's transition to competitors, you understand.
  
• The big issue is always the confidentiality of information. How to make so that only the necessary information fell into the hands of only the right people? How to protect the EMR from hacking? Many do not want to answer these questions simply by refusing to introduce an electronic system.
  
• In order for the EMR to be complete, it must have a patient history, not just fresh data. Accordingly, this story must be added to the base, and this is a lot of manual work, which requires not only time, but also financial costs. At this, many clinics are not ready.
  
• Now the format in which data is stored alone, but what if in the future it changes? Will it be possible to access the data? Very strange questions, I agree. But they discourage clinics from embracing EMR.
  

Clinical Decision Support System (CDSS)

In this section, we discuss the history of clinical decision support systems (CDSS), current research, commercial orientation, and potentially interesting areas for future research.



CDSS history

• 1960 - patient-computer
  
  Perhaps one of the earliest uses of computers to support doctors was a computerized patient interview system. The creation of such a system was prompted by the fact that the doctor, when interviewing a patient, often asks the wrong questions or forgets to ask the right ones. Thus, the history will be incomplete, and treatment is less effective. Accordingly, it will be much more effective to conduct formalized surveys. In 1960, this process was automated using a computer.
• 1970 - Expert System
  
  Expert System is a classic example of a decision support system. In the early 70s, research in the field of computer technology in medicine was mainly focused on the diagnostic process. It was believed that a computer with a large computing power, can greatly simplify the process of diagnosis. The first such expert was MYCIN, a system developed at Stanford University aimed at diagnosing and treating diseases transmitted through blood. MYCIN proved to be a very accurate diagnostician, making far fewer mistakes than generalized doctors. However, no one was in a hurry to use MYCIN. There were many different issues and disputes. Doctors did not want to be replaced. Lawyers did not understand who would be responsible for the diagnosis made by the computer. In addition, the establishment of the work of this system was very difficult, long and time-consuming process. Because MYCIN remained in history simply as a very successful experiment.
  
• 1980s - Real-Time Clinical Decision Aid Technology
  
  One of the most notable introductions of the computer world into the world of medicine is the patient’s heart monitoring system. In the 80s, these systems received automatic functions, such as detecting arrhythmias in an electrocardiogram. And in the 90th, these systems began to be replaced on a PC with special software.
  
• 1995 - PC and healthcare networking
  
  Many clinics began using PCs connected by a network to store and transfer data related to administrative tasks. This was an important step for the formation of a modern CDSS system.
  
• 2000 - our days - Reference databases and portable access
  
  Computer technologies have made reference information accessible to any doctor or patient. Today, almost everyone has a PC or handheld device (tablet, smartphone, PDA), which gives him access to the necessary medical information.
  

The unexpected consequences of the computerization of health care

As we have already understood, the computerization of the medical field is extremely important and must be developed. This process faces many challenges. Not everyone wants to spend money on the introduction of new systems, staff training. Someone is afraid of legal consequences in the case of data exchange between clinics. There is also the issue of confidentiality of information. All of these are factors hindering progress. But there are opinions claiming that this is not worth pushing, as unintended consequences may arise.

Depersonalization

Dr. Gale Thompson, a practitioner since the 60s, said that computerization leads us to forget that there is concern for the patient. Doctors have forgotten how to determine the patient's condition by their pupils, relying more and more on diagrams and graphs on computer monitors. With this view, fully agree and Stephen Angelo, a doctor from Connecticut. He told how once the patient monitoring system had “laid down” at his hospital. Doctors were confused, did not know what to do.



Of course, more and more relying on modern technologies, we forget about the good old methods. But, if computerization of health care reduces the number of deaths among patients, I’m ready to give up personalization, as such.

Medication errors

Some doctors argue that electronic systems, while helping to reduce the number of errors, but do not eliminate them completely. That's because a person, as a source of error, controls this electronic system.

This is incontestable, but the problem still remains in the human factor, and not in the system as such. To solve this difficulty, it is necessary to pay more attention to learning honey. staff. If the staff does not know how to use the system, then, of course, all its advantages lose their meaning. As long as there is at least one person in the industry, there will be mistakes.

Invalid information on the Internet

There are many articles on the web about various diseases, drugs, etc. Many of us used similar content for self-diagnostics and even self-treatment. Of course, information is power, but only when it is correct.



A lot of medical information on the world wide web contains errors. And this can lead to the fact that the patient will start the wrong treatment or simply ignore the potentially dangerous disease. This problem can be solved only by introducing standards for the accuracy of information and methods for its verification and control of publications.

Search for the necessary information

Storing the entire patient history in one e-folder allows the doctor to quickly access it. But will he be able to quickly find what he needs in this particular case? The huge flow of information that is necessary not only to see, but also to analyze, may delay the formation of history and diagnosis.

Conclusion

The world does not stand still. Computer technology more and more crashes into other areas of our life, introducing many new, good or bad, it is sometimes difficult to say. But progress cannot be stopped, relying only on the fear of something new. This also applies to medicine. Many diseases would remain incurable if some brave souls did not decide to treat them differently, not like before. The main thing to remember is that a person creates technology, a person improves it, and only he can be responsible for it.

Today, many clinics are moving to remote storage and processing of information. We also offer solutions for this type of customers, even solutions using the latest NVMe drives, which allow processing requests in large databases “instantly”. The data centers where the equipment is located correspond to the required levels of certification in the field of data security. And the geographical distribution and isolation of modules, even within the same location, allows you to organize the most fail-safe systems for clients of this kind.
