Problems existing in nucleic acid sampling and suggestions for improvement

The problems existing in nucleic acid sampling are: insufficient combined force of sampling points for nucleic acid detection, unreasonable scheduling of sampling and testing samples, and insufficient material supply support capacity. The rectification suggestions include: strengthening organization and leadership, doing a good job of sampling and launching, and strictly sampling operations.

exist problem

1. The resultant force of sampling points for nucleic acid detection is insufficient.

Although sample collection group, sample collection and transportation group, logistics material support group, support working group, etc. Insufficient coordination among these groups; Public security, civil affairs, transportation, publicity, ecology and environmental protection and other relevant departments did not play a good role in front-line posts, and the staff did not go to the site to personally direct, so the sampling site was chaotic and disorderly, and the requirements for 1 rice noodle were not well implemented.

2. The arrangement of sampling and inspection samples is unreasonable.

The county headquarters can't co-ordinate the dispatch of sampling and testing power, the sample dispatcher can't clearly grasp the testing ability and testing progress of each testing institution, the workflow of sample inspection is complicated, there are insufficient transport vehicles, the requirement of 2-hour sample delivery has not been implemented, the backlog of samples at sampling points is obvious, individual testing institutions have no sample reception and testing, and individual testing institutions transport samples beyond the testing capacity, so the reasonable matching between sample delivery and testing can't be realized.

3. Insufficient material supply support capacity.

Sampling points are not arranged and used in a list or ledger, and there is not enough follow-up support. After the staff changed their posts, there was a shortage of disposable articles such as isolation gown, protective masks and masks, and there were potential safety hazards in personal protection. Inadequate preparation of transfer boxes and vehicles in the jurisdiction affects the transfer effect.

Rectification suggestion

1, strengthen organizational leadership

The epidemic prevention and control headquarters of cities and counties should further strengthen the organization and leadership, strengthen the coordination and cooperation among departments, and the main responsible persons of the party and government should take the lead in coordinating the nucleic acid detection work of all staff in their respective jurisdictions.

Health, public security, civil affairs, transportation, publicity, finance, power supply, eco-environmental protection and other relevant departments should take the initiative and take the lead in setting an example to ensure that personnel's post responsibilities are well played, materials, facilities and equipment are well guaranteed, and all staff's nucleic acid testing work is done efficiently and cooperatively. Before testing, cities and counties should evaluate their own testing capabilities and verify the testing capabilities of third-party testing institutions.

2. Do a good job of sampling and launching.

It is necessary to organize the mobilization and management of sampling personnel in an orderly manner, issue sampling announcements in a timely manner, and announce the sampling scope, sampling time, sampling objects and frequency requirements to the public.

Community cadres, grid workers and other staff should give full play to mobilize and inform the sampled people in communities, towns and streets to sample at sampling points in different time periods, increase the allocation of management personnel, strengthen the order maintenance and personnel guidance at the sampling site, accurately mobilize personnel, avoid long queues, and reduce the risks brought by large numbers of people gathering in a short time.

3, strict sampling operation

Standardize sampling according to the relevant requirements of the sampling operation manual, and strictly supervise the operation process and all links to ensure the sampling quality. Standardize sampling, sealing and transshipment, and accurately dispatch transshipment specimens. After completing a single sampling 1 person, hand hygiene should be strictly disinfected or gloves should be changed (gloves should be changed immediately when the nose and mouth are contaminated or suspected to be contaminated), and gloves should be changed after a batch of samples are mixed to avoid cross-contamination.

During and after sampling, terminal disinfection and medical waste transfer should be carried out at the sampling site to resolutely prevent the sampling site from becoming a cross-infection source. All aspects of nucleic acid sampling and detection should be well collected, packaged, temporarily stored, handed over, transported and treated harmlessly.
