Specifically, the present invention relates to a medical diagnosis and treatment education system and a method for using the same, for analyzing a user's knowledge framework of diagnosis / treatment and problem solving strategies, and providing scoring and suggestions to promote users to learn experts efficiently and correctly. Diagnosis and treatment mode.

Diagnosis and treatment is an important clinical capability of medical personnel, and it is the key to the quality of care and patient safety. A diagnosis or delay in diagnosis will almost always have adverse consequences for the patient and has always been a major issue in medical disputes. In 2014, the Parliamentary and Health Service Ombudsman (PHSO) reported that 35% of medical complaints were related to medical diagnosis and treatment. The process of collecting medical history, conducting various examinations, and forming a diagnosis is considered to be a difficult and complex dynamic task, the so-called "reasoning task"; from diagnosis to the formation of a treatment plan Although the part of tracking and treatment is a static task, there are more rules to follow, but its processing errors will still cause serious injury to the patient. Trainees need to go through many cases under the guidance of many years before they can become experts and be qualified for this task independently. Therefore, the development of clinical training of experts is quite costly and often pays a painful price. In recent years, with the rapid progress of science and technology, medical knowledge has made medical behaviors more complicated and more risky. When patient safety and medical quality are being valued, people from all walks of life no longer allow patients to be the object of educational exercises. The chances of students approaching patients have been greatly reduced, and due to the general shortage of medical manpower in recent years, the manpower of teachers and supervision and guidance time has been reduced, and the overwork of students has made learning effects ineffective, so medical education is facing great challenges.

In the past, almost all education on medical diagnosis and treatment used "disease" as the teaching unit, separating basic medicine from clinical medicine, and teaching the order of normal and then the abnormal state. It is believed that before contacting "disease", After teaching basic medicine, visit the patient after teaching the whole medicine. However, what students encounter in clinical practice is not "disease", but patients and the "symptoms" they present. They need to use basic medical knowledge to solve patient problems. After years of clinical practice, they have repeatedly accumulated expert degrees. According to the traditional teaching mode mentioned above, students often lack interest and have poor learning effects.

An object of the present invention is to provide a medical diagnosis and treatment education system and a use method, which provide medical personnel with the opportunity of repeated practice without stress and without patient safety concerns, so that students have the learning experience of hands-on exercises in real life.

Another object of the present invention is to provide a medical diagnosis and treatment education system and method, provide an interactive education experience, and enhance students' learning interest and learning effect.

Another object of the present invention is to provide a medical diagnosis and treatment education system and use method, which can analyze and evaluate students 'diagnosis and treatment performance, give immediate feedback, and use this scoring to make the difference between students' cognition and expert diagnosis or treatment, so Self-improvement and the ability to learn autonomously.

1A and 1B are schematic diagrams of an embodiment of the medical diagnosis and education system of the present invention; FIG. 2 is a flowchart of the medical diagnosis and education method of the present invention; FIG. 3A is a schematic diagram of an image of a realistic scene displayed by an operation interface device; FIG. 3B is a schematic diagram of another image screen displayed by the operation interface device; and FIG. 4 is a schematic diagram of a standard diagnosis architecture flow.

The empirical results show that there is not only a difference in the amount of knowledge in the mind between the medical expert and the novice, but also the "knowledge framework" is very different, and different "disease diagnosis strategies" are used to solve clinical problems. The following sections introduce the "knowledge framework" and "disease diagnosis strategy" in the medical field.

How the acquired knowledge is organized into a combined "knowledge framework" determines the efficiency of similar situations in the future. This "knowledge framework", known as the knowledge representation, can be mainly applied to the following types of "knowledge framework" for medical staff education (1) Predicate Calculus; (2) Frames; (3) Semantic Networks; (4) Triplets; (5) Production Rules; (6) Neural Networks.

As for the "disease diagnosis strategy", traditionally, in order to obtain a correct diagnosis, experts will first form a number of hypotheses in their minds. Based on these hypotheses, they will collect evidence and make a comparative analysis to obtain the final diagnosis. The model is called "hypothetic-deductive reasoning" (HDR), and it was used in the medical education field to think about this model. To teach students a clinical diagnosis. However, since 1980, scholars have begun to doubt this HDR mode of thinking, because research has found that the hypothesis formed by experts is very different from the quality of decision-making by experts. In fact, experts often use HDR more than HDR. Efficient speculative model to produce better quality hypothesis. Experts generally use two types of reasoning operations, "intuitive" and "analytic". Intuitive thinking is instinctual and reflective thinking, which can be guessing or "recognizing disease pattern recognition"; analytical thinking is Based on science, logical reasoning, causality, possibility, and decision-making processes, Hypothetical deductive reasoning and Scheme inductive reasoning (SIR) are assumed to belong to this category. Students should learn such dialectical strategies from experts, but have not yet been effectively applied to trainees.

The present invention uses an imaginary interactive digital system to train medical personnel to implement medical diagnosis and treatment in an "expert dialectical thinking mode", fully combining "experiential learning" and "adult learning theory" in practical exercises; emphasizing that clinical learning must Basic biological medical knowledge is fully integrated; brought into the clinical situation early in the practice of medicine, the digital system provides immediate feedback based on data generated by the interaction between the user and the patient to improve the learning effect; this system not only provides the learning of medical knowledge and skills, It also includes: self-directed learning, communication / interpersonal relationships, professional literacy, and teamwork training that fits the medical system. The dialectical thinking model of medical experts used in this system is obtained by reviewing the literature and interviewing experts in various fields, and extracting its "knowledge framework" and "disease diagnosis strategy".
