Chapter 484 "Special Medicine"

Lin Qiang underwent a complete set of physical examinations, including whole-body CT scans and mNGS sequencing.Inspections are expensive and time-consuming.But for an experimental group that stuffed eight TESLA V4 accelerator cards in a 100U chassis, the cost of this part is actually not unbearable.

Strictly speaking, Lin Qiang was the subject of the old thing's first practical experiment.Although the researchers in the group have different opinions on whether it is necessary to apply the old thing to this intractable disease in the first experiment, but since it has been decided, everyone still hopes to go all out and try to help the old thing Collect more information.

The more information there is, the more accurate the diagnosis that old things can make will theoretically be.

If you want to know whether there is any problem with their AI algorithm design, it is definitely not enough to rely on the case reports that get the answer in advance—when manually summarizing and recording cases, people will always unconsciously remove some that are not "direct" data to ensure that the report itself is easy to read.

And these processing methods used to ensure that other people read smoothly, in fact, saved the old man a lot of trouble-the human body symptoms are too many, whether these redundant variables can be eliminated, and the cause of the disease can be accurately found, this is the old man. The biggest test things need to face right now.

What made this group of experimenters feel crazy was that even though they tried their best and tried their best to get all the data for the old thing, they couldn't immediately verify whether the old thing's calculations were correct—no one knew what Lin Qiang got. What kind of disease, even the diagnostic conclusions drawn by Dean Wu Youqian and the experts of the Tri-Service Medical University have considerable room for ambiguity.

AI designers and operation managers are not doctors, they are standard science students.The result of the calculation is either a definite A or B, or there are multiple results within some definite range.The result is good now, the calculated answer does not match the standard answer.If it doesn't match at all, it's fine, at least there is a clear "you're doing it wrong, you need to re-check the process" signal.There are clear results, but the reference answer is vague - how can this be referenced?
Wu Youqian looked at the anxious-looking operation personnel in front of him, and waved his hands nonchalantly, "Look at you, you are so helpless." He took a sip of tea with a smile, "A doctor encounters a diagnosis in the clinic. Unknown patients need to be ruled out by some means. You are asking the doctor to hit the bullseye at the first thought and find the disease problem. Let alone Sun Lien, you can’t do it with any doctor. The old thing has only been corrected for less than a year, isn't the correct rate almost catching up with him?"

"Dr. Sun's misdiagnosis rate is too low. If there is no video testifying for every diagnosis, I must suspect that he has cheated." The leading experimenter wiped the sweat from his face, "His average The misdiagnosis rate is less than 18%, and the misdiagnosis rate of emergency related diagnoses is only about 10%. The average misdiagnosis rate of the old stuff is 25%. If Dr. Sun’s gynecology and obstetrics misdiagnosis rates are relatively high, he would really be a monster .”

"The design direction of the old thing is 'a reference for doctors' clinical diagnosis'. It was not designed to replace doctors from the beginning." Wu Youqian looked at the researchers with different expressions in front of him, and explained with a smile, "I can understand your thinking. The idea of ​​perfecting your results to the point of perfection, but doing scientific research must also respect objective facts—no matter how hard you try, treatment and diagnosis are always the professional work of doctors. It is impossible to replace them. It makes a useful, dependable tool, and that's what you're working on at this stage."

Although many practitioners are reluctant to bring up the topic of misdiagnosis rate, it must be admitted that misdiagnosis is common in medical activities at home and abroad.Leaving aside the intentional misdiagnosis that needs to be referred to the judicial department, the average misdiagnosis rate of doctors is about 30%.These misdiagnoses may be due to different manifestations of the disease, atypical manifestations, or inexperienced doctors, or even patients' concealment of medical history, resulting in errors in diagnosis information and so on.

In China, in addition to the above reasons, work stress and fatigue also account for a huge proportion of doctors' misdiagnosis.The main reason why Sun Lien can achieve an average misdiagnosis rate of 18% is not because of his outstanding ability, but because the daily cases handled are limited, and he can spend more time without directly contacting patients. The energy is in each individual case.And he can perform any inspection he wants on each case almost without restriction, regardless of whether the family members of the patient can afford the inspection fee, or whether they are willing to cooperate.

Sun Lien's situation is a special case. It is no exaggeration to say that in the "Ninth Consulting Room" of the laboratory building, Sun Lien is definitely the most nourishing doctor in the whole country and even the world.But the reality is very different from this ideal situation.

The project team will propose that the purpose of AI diagnosis is also here. If a set of AI algorithms based on cloud services can be used to provide doctors with a "second opinion" that will not have any complaints, and will not make mistakes due to fatigue and work pressure ", then it is bound to significantly reduce the misdiagnosis rate.

For now, however, it seems the old stuff still has a long way to go.

"Just sign these two documents?" The next morning, Sun Li'en received a call from Mrs. Lin in the hospital.The fourth hospital does not have a psychiatric department, so after meeting with Sun Lien and signing the corresponding permission and notice of the experimental group, Wu Youqian led people to directly take Sun Lien, Mrs. Lin, and Lin Qiang to the Affiliated Hospital of Ningyuan Medical College.There is a psychiatric department here, which can treat Lin Qiang who was initially diagnosed with "chronic fatigue syndrome".

Mrs. Lin and Sun Lien went to the toll window to register for the psychiatric department. From registration to payment, they avoided Lin Qiang from beginning to end.In order to prevent some mistakes in the middle, even the registered items are written as "special needs clinic".

"You do feel very uncomfortable recently, with muscle pain..." The doctor in charge of the consultation was the deputy director of the psychiatric department who Wu Youqian had warned hundreds of times the night before.As the deputy director of a large tertiary hospital directly affiliated to a medical school, Director Mei should have been very pompous.It's a pity that Wu Youqian was already the dean when Director Mei was in school. The teacher has orders, and the students really dare not stab them.Director Mei could only honestly conceal his true identity and start the diagnosis directly.After re-examination, he asked Lin Qiang to have breakfast first under the pretext of "needing a final consultation", while he went to the room where Wu Youqian and Sun Lien were waiting.

Director Mei took off his mask, and said to the two, "There is no problem with the diagnosis of chronic fatigue syndrome. If there is no decrease in the absolute count of CD4 cells, I am actually more inclined to mass hysteria."

"That is to say, it can be treated, right?" Wu Youqian nodded, and he glanced at his watch, "Then let's strike while the iron is hot and deal with this problem quickly."

"The idea of ​​using indigo carmine injection as a placebo is indeed very creative." Director Mei was very interested in this treatment plan, and put forward his own views on the details of the treatment, "Ordinary syringes are transparent, and indigo carmine The color of the injection is the same as the stained urine. I suggest going to the stomatology department to borrow a metal syringe and stick the observation window with black tape, even the gods will not be able to see what it is.”

"You can also ask the sister nurse who is injecting to wear the lead suit in the CT room." It is good to start a brainstorming sharing session. The treatment effect should be better."

The placebo effect is generally directly related to two conditions, one is "anticipation" and the other is "conditioning".The two can regulate and interact with each other.Sun Li'en has already planned the expectation for Lin Qiang in advance, "One injection will cure the disease when the medicine arrives".At the same time, this expectation is enhanced by means of conditioning.Next, it's time to see the real chapter.

Lin Qiang sat in the consulting room, a little embarrassed.His wife was sitting not far from him, but she seemed to have warnings of "don't talk to me" all over her body.He wanted to speak several times, but in the end he gave up the idea and stared anxiously at the door of the consulting room.

"Lin Qiang, right?" The heavily armed nurse came in with a plastic shock-absorbing box, and when she saw Mrs. Lin who was also in the room, she asked, "Are you a family member?"

"Yes." Mrs. Lin nodded, stood up and said to the nurse, "I'll wait outside." After speaking, she walked out the door by herself.I didn't wait for the nurse sister to reply at all.

Lin Qiang glanced at his wife's back anxiously, but his attention was quickly attracted by the box in the nurse's hand.

"This is a special medicine for you." The sister nurse adjusted the box in her hand without showing any signs, and put it on the table to open it - a silver-white syringe with a shiny metallic luster appeared on Lin Qiang In front of him, and introduced, "Because this medicine is radioactive and reacts to light, it must be injected with a special metal syringe." While disinfecting Lin Qiang's arm, she asked, " Has the doctor told you the process of taking effect of this medicine?"

"No." Lin Qiang shook his head nervously, "They only said that the medicine takes effect very quickly."

"That's right. But this medicine doesn't work for some people." The nurse continued to follow the predetermined line, "After the injection, you can go to the bathroom to check the urine in about fifteen to twenty minutes. Yes. If it takes effect, the urine will turn blue. If it doesn’t change color, it doesn’t work, so you have to tell the doctor right away, okay?”
