Chapter 4308 [397] The Direction Given

What is over-checking.

Excessive examination should be one of the contents of excessive medical treatment.

Excessive means going too far, which is equivalent to not doing enough.

This once again shows that in medicine, if you are overzealous and do too many things, it may not be a good thing or a bad thing. Medicine only pays attention to accuracy in doing things.

All of this points to a central question: how to determine the degree.

Dr. Xie Wanying told the truth: "The measurement of these degrees in medicine requires a large amount of clinical observation data to determine."

For example, the upper and lower limits of normal values ​​of blood indicators that we know now are all derived from a large number of case data accumulated over a long period of time, and are standards determined by professional national institutions.

Some of the prescribed values ​​even differ from country to country.

Under such circumstances, if a country has not yet formulated guidelines on "degree" in this regard, it can learn from other countries' experience in this regard.

After all, human beings live on the same planet, and the differences are not very big. We can learn from it and then make decisions based on our own national conditions.

The use of CT lung examination as a physical examination item for early-stage lung cancer screening is in full swing in some countries and has made great achievements. For example, in a certain country, they first conducted such a project for pilots and found that the detection rate of lung cancer is close to 2 to 4%, and some of it is in the early stage. It can be said that it can save and prolong the lives of some patients. When Dr. Xie was talking, Dean Wu and Section Chief Yang kept swiping their pens on their notebooks, encouraging her to continue talking quickly.

Another large country, known as the country with the most developed medical technology on the planet, has completed the data accumulation of this part of the work and concluded that early-stage lung cancer screening using CT scans detects pulmonary nodules, which generally refer to lung diameters smaller than Or a round or irregular-shaped lesion equal to three centimeters, with imaging findings showing increased density shadows.

According to different densities, they are divided into three categories: solid nodules, partially solid nodules, and ground glass density nodules. Partial solid nodules have the highest probability of malignancy.

The trend shown by all these foreign data is that it makes sense to do such early screening. But don’t forget that these examination items have target groups. These target groups are not imagined out of thin air, but are guided by past medical data.

For example, pilots and airport ground staff are more likely to be exposed to high-risk environments than ordinary people, so this inspection is necessary.

To put it simply, for example, if you have a history of lung disease, smokers, or people exposed to high-risk environments, or older age groups, you should pay more attention to this type of examination and be more careful about the chest X-ray examination we used to do. distinguish.

To sum up, whether it is an excessive examination depends on the target group. This is also a relatively unified academic understanding in the medical community in the future. Now Dr. Xie Wanying directly told the big bosses at the scene this information.

After Dean Wu records it, he should report it to the people above.

After listening to her words, the two leaders were silent and thoughtful, and the expressions on their faces gradually became more relaxed from the worried ones at the beginning.

There is another difference between doctors and ordinary people. The fear expressed in medicine is also due to the unknown of the future.

When Dr. Xie revealed that some medical measures were effective and could determine the general direction, the bosses gradually calmed down.

Thank you for your support, good night, dear friends~
