The methods used in disease surveillance belong to

The methods used in disease surveillance belong to descriptive research.

Disease surveillance is an important work in the medical field. It mainly uses modern scientific and technological means to track, monitor and analyze the health status of people or individuals and its influencing factors, so as to quickly grasp the development trend of epidemic situation, find and issue early warning in time, and provide scientific data support and prevention and control strategies for effectively coping with diseases.

At present, the methods used in international disease surveillance mainly include the following:

1, traditional epidemiological survey

Epidemiological research is one of the core contents of disease surveillance. We mainly track and monitor the epidemic situation through questionnaire survey, field investigation and laboratory detection, and grasp the origin, development trend and transmission route of the epidemic situation.

Compared with other methods, epidemiological survey has the advantages of low cost, obvious effect and simple operation, but the survey results are greatly influenced by the investigator's subjective cognition and memory.

2, hospital information system monitoring

With the continuous improvement of medical information level, more and more hospitals began to use information systems to carry out disease monitoring. By analyzing doctors' prescriptions, medical records and other information, we can collect corresponding data and give an alarm in time to give an early warning of hospital infection, tuberculosis and infectious disease outbreaks.

Compared with the traditional investigation method, the hospital information system monitoring method not only simplifies the operation process, but also greatly improves the work efficiency.

3. Monitoring based on medical insurance data

Medical insurance data monitoring refers to monitoring the epidemic trend of specific diseases by mining and analyzing the medical insurance database. Compared with other methods, this method has the advantages of wide coverage and reliable data source, and can obtain the medical data of patients quickly and accurately.

4. Internet big data mining

With the advent of the Internet era, more and more information is uploaded to the Internet platform. In these massive information, a large number of data containing disease information and related characteristics can be found through data mining and analysis technology, which provides accurate and scientific data support for disease monitoring and prediction.

5. Molecular biological detection

Molecular biology technology is also widely used in disease monitoring, including rapid detection and monitoring of infectious disease pathogens and diagnosis of new infectious diseases. The advantage of this technology is high sensitivity and specificity, and it can provide the most accurate pathogen detection results.
