On August 27, the first group of Sichuan provincial aid Hainan nucleic acid testing team members arrived in Chengdu. The remaining players will continue to station in Hainan to perform nucleic acid testing tasks. According to the statistics of the Provincial Health and Health Commission, in the three air -film square cabin laboratories built in Sichuan, 798 medical staff assisted Hainan to complete 1.83 million nucleic acid tests from August 7th to August 27th from August 7 to August 27 None of the mission, none of the medical staff were infected.

1.83 million, medical staff 0 infections, what kind of stories behind the two data have? In the past week, Sichuan View journalists have continued to track and talk about 5 medical players.

From "dividing by car" to "divide in quantity"

Nucleic acid detection efficiency has improved as a whole

A copy of nucleic acid samples want to be tested smoothly, which is inseparable from the "processing" of the front processing group in the sample receiving compartment -they want to complete the "first step" into the cabin: sample receiving, box removal bags, sample numbers, and code scanning code scanning code scanning code scanning. Entrying, etc. During the period, it is necessary to disinfect multiple times outside the nucleic acid sample. The work seems not complicated, but once a large number of samples are encountered, the challenge is not small. "The workload of this time was 3 to 5 times that of the hospital." Said Yang Yan, the leader of the former treatment team of the Gas Film Team of the Sichuan Provincial Nuclear Nucleic acid Inspection Team and the former head of the Affiliated Hospital of Sichuan Medical College.

In the complicated pre -processing work, Yang Yan found that it was "imbalanced". It turned out that Sichuan was located in the three air film squares laboratory in Hainan, and each had a front processing cabin -respectively A1, A2, and A3. At the beginning, the number of sample sample samples was allocated in the "Sample car" unit. "You don't know how many samples are in the sample car. Some of the nucleic acid samples loaded with sample cars, and some are relatively small, which means that the samples received by the three front processing group are uneven. Unexpected 'situation. "

In order to reasonably allocate medical resources, Yang Yan proposed that the front processing group of the three air -films square cabin laboratory changed the original "distribution of the car" to the "distribution of the box, take turns to be the head" method. Essence "It can ensure that the workload of the three groups is roughly comparable. While improving the overall detection efficiency, it is not too tired to let the players be too tired."

At the same time, at the same time, the gas film team of the Affiliated Hospital of Sichuan Medical College, where Yang Yan is located, also pays attention to the reasonable distribution of staff. One week before arriving in Hainan, Yang Yan found that there was a certain rule of sample time -between 7 pm and 1 am, the number of samples was relatively small. The personnel of the person in this class at 7 pm to 1 am, and flexibly arrange two team members and "motor groups" several members to "prepare". If the nucleic acid samples are not accepted by the staff on duty, if the number of samples within this period of time, the number of samples within this period of time will be received. The "motor group" went into battle. "This model reduces the pressure of the previous processing group and helps the reasonable allocation of medical resources." Yang Yan said.

Can "find questions" and "get the scriptures"

Three -cabin "cross -checking" makes the nucleic acid detection process more standardized

After the nuclear acid detection sample is "processed" by the previous processing group, it is sent to the nucleic acid extract compartment and nucleic acid extension. In these two cabins, the test results must be obtained through several processes.

Zhong Jialing, a member of the Sichuan Provincial Nucleic acid Inspection Team and the deputy leader of the Qi Milk Team of the Sichuan Provincial People's Hospital, introduced that in order to ensure the accurate efficiency of the nucleic acid detection process of the three air film square cabin laboratories, Sichuan established an 18 -person " Nucleic acid testing and supervision group ", usually cross -checking the three air membrane laboratories, namely B cabins, C -class C, C -class C -class, C -class check B. In addition, the team leader of the nuclear test team of the three air film square cabin laboratories also inspects the gas membrane laboratory every day and commented at the regular meeting.

Zhong Jialing, a member of the "nucleic acid detection supervision group", frankly said that the three -cabin mutual inspection method helped each other to find the problems that were not easy to find before "self -examination", which was conducive to more standardized nucleic acid detection processes. "The authorities are fascinated, and the bystanders are clear." Zhong Jialing for example, the chlorine -oriented disinfection of the environmental disinfection needs to be prepared and marked the daily date of the preparation. It will fail to be effective after more than 24 hours. Sometimes the update date is forgotten, and the user will deal with it. "This problem is commonly found during cross -examination. After pointing out the problem, everyone actively rectifies, and no such problems have occurred." Luguelu's work photo. Zhou Yi was taken.

"I have participated in the prevention and control of the epidemic in Beijing and other places. The difference between this time when I came to Hainan, it is also this" cross -check -and -mutually check "mode." The doctor of the inspection department said that as a quality control person, they will take a sample to test whether the results issued by the three laboratories are similar. "For example, a positive sample we will detect the three air film square cabin laboratories at the same time, and then analyze whether the CT value (related to the virus load in the human body) is consistent. There are problems with accuracy. Although these have not happened, we still have to do the assumptions of "not afraid of 10,000" in case of "not afraid of 10,000."

Cross -check also helped "learn from" between three cabins. Zhong Jialing learned a good way from other laboratories. "Previously, after receiving the nucleic acid sample in the previous processing group, we generally only registered nucleic acid sample board numbers. Now, we have added registered number of number of sample board boards and receiving personnel information. The test results trace the source. "

In addition to the previous treatment group and nucleic acid detection group, there are also quality control protection, technical guarantee for the technical guarantee ...

——In for the "echo of the tubes", the reasons for the "pipe tube to have echo", and the Capital Lu will refine, summarize, and analyze each "unqualified sample" with colleagues one by one. "Samples of" Unqualified Samples "occur, such as sample tube leakage, air tube, noes, etc. caused by the sampling end, or occasionally scanning the code of the sample receiving end. The residents cannot receive the test results. "Luguelu said that in addition to finding the reasons, induction, and summary of each" unqualified sample ", she and her colleagues will continue to" stare "whether they will make the same" error "of the same" error " Essence "To ensure that each nucleic acid detection tube from our laboratory is a clear explanation to the people of Hainan."

—— When the information guarantee team of the Sichuan Provincial Nuclear Acid Detective Team in Hainan Province arrived in Hainan, it encountered technical problems: a system used in Hainan's gas film compartment in Sichuan Provincial People's Hospital could not be connected with Hainan's health code. Time was urgent. Huang Qingxi, an information engineer of the First Affiliated Hospital of Chengdu Medical College, and colleagues exported the data from the system. After manual modification, they were introduced into the Health Code of Hainan. The live broadcast method is conducted online training.

——Xia Jiao, deputy captain of the gas film laboratory of Southwest Medical University Affiliated Hospital, Xia Jiao, the leader of the hospital feel and logistics support team, recalled that when the hospital's sense prevention and control team was built in the laboratory, the internal dynamic line process and system, settings, and settings were reorganized according to the on -site environment. In addition to personnel, materials and dirt channels, they need to enter the cabin daily inspection to perform nucleic acid samples for 798 medical staff in Hainan every day; the door handlers and elevator buttons such as door handles and elevator buttons are riding with them. Car and other items are sampled and tested.
