ABSTRACT
Objective To evaluate the quality of infectious disease surveillance data and provide scientific basis for improving data quality and health decision-making. Methods The comprehensive index of infectious disease monitoring system evaluation and the integrity, accuracy and reliability of infectious disease report data were used to evaluate the quality of infectious disease monitoring data in multiple dimensions. Results In 2021, The comprehensive evaluation index of infectious disease surveillance system was 98.40%. In terms of data integrity, 1 105 data were missing, and the incomplete rate was 1.46%; In terms of data accuracy, 1978 cases were not accurately, rate of accuracy was 26.72%; In terms of data reliability, the card reporting rate of tertiary medical institutions accounted for 67.05%, the diagnosis rate of confirmed cases was 27.74%, and the correction rate of report card was 28.48%. Conclusion The accuracy and reliability of infectious disease data are insufficient, and new methods for infectious disease monitoring data quality are expanded to make up for the lack of data quality evaluation of the current national epidemic system.
ABSTRACT
Objective To provide a scientific basis for the prevention and control of notifiable infectious diseases in preschool children, and to improve the service level of children's health management. Methods Infectious disease information was obtained from the Infectious Diseases Reporting Information System of Chinese Center for Disease Control and Prevention, and the number of permanent residents was obtained from Shanghai Statistical Yearbook. Excel 2019 was used to organize and calculate data and draw charts. Descriptive statistical methods were used for analyzing disease ranking and epidemic trends. Seasonal characteristics were calculated by concentration M value and circular distribution, α=0.05. Results In the reports of notifiable infectious diseases for preschool children, boys (60.93%) were significantly more than girls, and the largest number of children reported were 3-4 years old (43.19%). The unit with the largest number of reports was Shanghai Children's Medical Center (47.31%). The order of the diseases was hand, foot, and mouth disease (HFMD), chickenpox, mumps, scarlet fever, influenza, and infectious diarrhea. HFMD accounted for 73.52% of the total (46 541/63 304). The incidence of notifiable infectious diseases among preschool children had been increasing since 2005, reaching a peak in 2014, and then showing a downward trend overall. In the 17 years from 2005 to 2021, there were 3 years (2008, 2010, and 2018) with a concentration M value of 0.3-0.5, indicating that there was a certain seasonality, and one year (2020) with an M value of 0.5-0.7, indicating obvious seasonality. The peak of incidence mostly occurred from June to August. Conclusion It is suggested to strengthen the health guidance of HFMD in preschool children and increase the vaccination rate of HFMD vaccine to reduce the health harm of HFMD to preschool children. The prevention and control of COVID-19 has had an inhibitory effect on the occurrence of notifiable infectious diseases in preschool children.
