The Accident and Emergency Department of public hospitals serves a large number of patients. In recent years, the Hospital Authority has introduced AI artificial intelligence technology to help diagnose cases more quickly and accurately.
In March this year, the emergency department of Tin Shui Wai Hospital tried to use AI technology to assist doctors in examining patients’ lung X-rays. A total of 920 X-rays were analyzed on the 10th. Nearly 20% of X-rays involving 174 patients were detected by the AI system. An alarm was sounded when abnormal shadows were detected, and it was finally found that 4 of the patients were newly diagnosed cancers.
At present, the relevant technology has been fully applied in 18 emergency departments of public hospitals.
Lui Chun-da, a consultant physician in the Accident Department of the New Territories Western Hospital Cluster of the Hospital Authority, pointed out that for every 10 accident and emergency department patients, 2 to 3 people need to undergo lung X-ray examinations, so the number is very large. There were 18 public hospitals from January to November this year. The emergency department has accumulated more than 600,000 lung X-rays. In March this year, the emergency department of Tin Shui Wai Hospital tried to use AI technology to assist doctors in diagnosis. The AI system is used to detect abnormal shadows in the X-rays. When an abnormality is found, the system will An alarm sounded to remind the doctor.
Lei Junda said that after analyzing the detection results of a total of 920 lung films on the 10th, there were 174 patients’ X-ray films with AI prompts. Among them, 27 doctors looked at them in detail and confirmed that they belonged to the tumor or the shadow of the tumor, and then compared them. After the medical records, it is believed that the 8 films are the new shadows, and finally 4 patients are determined to be the new shadows with cancer.
With the introduction of AI-assisted lung filming technology, Lei Junda pointed out that it is not to shorten the time for doctors to view the film, but to improve accuracy and increase safety. The room is ready to deal with problems."
AI technology will also be applied to the lung film review in the emergency department the next day. Lei Junda said that senior doctors in the accident and emergency department will review the lung film of the previous day every day to prevent omissions. AI technology can help the lungs Film classification, some lung films that have sounded alarms will be listed as priority review categories.
The senior medical information manager of the Hospital Authority, Dr. Chen Ka-yin, said that AI technology can also be applied to other diagnostic procedures, including assisting in detecting the correct position of the stomach and throat after the patient’s stomach is inserted. It is currently in the emergency department of Tin Shui Wai Hospital and the emergency department of Tuen Mun Hospital. It can also be used to assist in detecting whether the hip X-rays of fall patients have minor fractures, which can help provide early treatment. It is planned to be in Tin Shui Wai Hospital, Tuen Mun Hospital and Queen Mary Hospital in March and April next year. Try it out.
