How many people are suffering from “naked test”

in April this year, Chen Shaohua, a member of the Guangzhou Municipal Committee of the Chinese people’s Political Consultative Conference, made the term “naked inspection” cause widespread concern in the society. He said that the vast majority of hospitals do not have any protective measures when they do X-ray examination for patients, and according to the research of the 1nternational Commission on radiation protection, in a city of ten million people, about 350 people may be exposed to X-ray to induce cancer, leukemia or other genetic diseases every year. Moreover, the Ministry of health of the people’s Republic of China has clearly stipulated that doctors should shield sensitive organs near X-ray exposure when they diagnose and treat patients, but many hospitals have not implemented it

after more than two months, the reporter of life times visited many top three hospitals in Beijing again and found that the problem of “naked examination” has not been paid attention to and solved, and many patients are indifferent to it. On the contrary, many foreigners living in China told reporters that foreign countries have very strict requirements on CT, chest X-ray and other protection work. Because of the fear of radiation, they dare not even do X-ray examination in China

the first-class hospitals suffered from “naked examination”

on July 21, the reporter investigated Beijing Tongren Hospital, Beijing hospital and other top hospitals in China. There was a long line in front of their CT examination room and CT registration office, and a large number of waiting people filled the corridor. However, when the reporter asked a number of patients from the examination room one by one, only one patient in Tongren Hospital said that the doctor gave him protective clothing during the examination. 1n front of the X-ray examination room on the first floor of the inpatient department of Beijing hospital, a young woman pushing an old man in a wheelchair just received the examination report. She told reporters that not only did the doctor not let the patient wear protective clothing during the examination, but also she did not wear it as an escort. But before entering the examination room, she clearly saw the propaganda poster on the wall outside that the escort should wear protective clothing

in the investigation, the reporter found that the phenomenon of “naked inspection” is more common, and medical staff rarely take the initiative to provide protective clothing. Ms. Zhang, who has had a physical examination in the physical examination center of Peking Union Medical College Hospital, has a deep understanding of this. “When 1 got to the chest X-ray room, the doctor directly told me to stand in front of the instrument. 1 was worried that radiation was bad for my health. 1 asked to wear protective clothing on my own initiative, and then the doctor reluctantly took out a set from under the shelf and gave it to me,” she said There are only a few patients with protective consciousness like Ms. Zhang. 1n most cases, the doctor will not tell the patients the harm of radiation, and the patients themselves are not aware of it. 1n Tongren Hospital, a patient said to the reporter indifferently that the X-ray was only taken once in a while, and it was over soon. There would be no problem

abuse leads to potential dangers

in sharp contrast to the domestic “naked inspection”, even if taking an X-ray of a tooth abroad, the patient will be fully armed. Our reporter in Germany has a profound experience on this. Before filming, the doctor introduced the X-ray radiation process to him in detail. He personally helped the reporter put on heavy lead protective clothing, covering the neck, chest, lower body and other parts, and also wearing a protective hood. When everything is ready, the doctor will press the shutter

Li Kuncheng, director of Beijing medical imaging quality control and 1mprovement Center and director of Radiology Department of Beijing Xuanwu Hospital, believes that inadequate protection is very common in China, and the reason why foreign countries do well in this aspect is that there are few patients in hospitals” For example, CT, they do about 20 patients a day, and a hospital in China has to do at least 100 or 200 patients a day. Although the state has relevant regulations, the vast majority of hospitals are equipped with protective clothing, but if every patient is wearing it, it is too troublesome and a waste of time, and the inspection will not be finished. “

as for the hazards of X-ray, studies conducted by Oxford University and cancer research center of the UK have shown that 0.6% of the new cancer cases in the UK, 1.5% in Germany and 3.2% in Japan are caused by X-ray and CT examination. 1t is more harmful to pregnant women and children, will seriously damage the development of children’s intelligence, but also lead to fetal malformations. However, Zhou Cheng, executive vice president of China Medical 1maging Technology Research Association, vice chairman of Radiology branch of Chinese Medical Association, and director of Radiology Department of Beijing hospital, pointed out that this is only an inference, and there is no convincing evidence in clinical practice. But he also acknowledged that the potential risks of X-ray examination certainly exist, especially when it is abused. The Radiology Society of Chinese Medical Association once published a set of data: there are about 250 million people receiving X-ray examination in China every year, but 20% of them have no clinical significance. CT abuse is more common, and some hospitals even lower the price to attract patients< According to the relevant regulations of the Ministry of health, the radiation dose received by a continuous radiologist in a year should be less than 20 mSv, while the X-ray dose is 0.02-0.03 mSv, and the CT dose is 6-8 mSv. Feng Xiaoyuan, President of Shanghai Medical College of Fudan University, chairman of the radiology branch of Chinese Medical Association, and director of the Department of radiology of Huashan Hospital, pointed out that the amount of radiation in routine examination is within the scope of human safety, but we should try to do less. Adult physical examination, at most once a year to do CT and other X-ray examination, repeated physical examination is not necessary. 1f you see a doctor, you should decide whether to do X-ray examination according to the patient's condition. We can ask whether other methods, such as MR1 and B-ultrasound, can achieve the same effect, and try to choose the method with small amount of radiation and ensuring the inspection effect. He also reminded: take the initiative to ask for radiation protection before inspection. 1f the patient asks for protective equipment, the hospital must provide it. Gonad, thyroid and other areas highly sensitive to X-ray should be protected do not enter the examination room if not necessary. Don’t go in the examination room when the red light is on. Try not to accompany the patient for X-ray examination. 1f it is necessary, wear protective clothing pregnant women and children need to be most vigilant. 1f not for special needs, pregnant women 8-15 weeks of gestation should refuse abdominal X-ray examination. Many mothers would eagerly ask for CT after their children were injured, but did not consider the radiation problem. American Journal of radiology has found that children’s CT scan detection is not as effective as you think, only 7% detected intracranial injury
