Evaluation Study On Perform Ance And Quality Of Influenza Monitoring System In Jining City

BackgroundInfluenza is an acute viral contagious respiratory disease caused by influenza virus, with wide and rapid spread trend and serious harm. Influenza viruses are grouped into three types, designated A, B, and C. There have been4influenza pandemics During the20th century, which influenced the development of social economy, and seriously threatened people’s lives and properties. Response to the pandemic (H1N1)2009, China started to expand the national influenza surveillance network project, the sentinel hospitals and network laboratory increased to556and411, respectively.17cities have set up a sentinel hospitals and network laboratory in Shandong province, Jining Nol people’s hospital and Shizhong District maternal and child health care hospital in Jining city were national influenza surveillance sentinel hospitals, center for disease control and prevention of Jining city was Influenza surveillance network laboratory at the national level. To analyze the trends of H1N1epidemic from2010to2012, and provide evidence for further H1N1prevention and control. This study was done to understand the performance of the influenza surveillance system operation status and evaluate work quality.ObjectiveTo understand the performance of the influenza surveillance system operation status, monitor dynamic changes of influenza-like cases, analyze epidemiological characteristics and trends of influenza, virus type and activity level of influenza as well as aberrance of the surface proteins antigenicity of influenza virus. To find influenza-like cases together or outbreak timely, identifying the virus type virus type, and control the outbreak. To evaluate influenza monitoring system monitoring quality, analyze the problems and improve monitoring quality. Materials and MethodsThe data were collected from China influenza surveillance information system from April2010to March2012, which include monitoring data of influenza-like cases, monitoring data of etiology, monitoring of outbreak and evaluation of monitoring quality. Data were analyzed using by Statistical Package for Social Science (SPSS)15.0.Main Results1. Monitoring of influenza-like illness A total2930366cases of outpatient and48976cases of ILI were reported, ILI rate was1.67%, which was less than2009to2010influenza pandemic. ILI rate of National influenza sentinel influenza surveillance hospitals was higher than provincial influenza sentinel influenza surveillance hospitals. The highest in the age group was in group of0to4years group.2. Monitoring of etiology1743ILI cases’nasal swabs were collected from two National influenza sentinel influenza surveillance hospitals in2010to2012,44strains of influenza virus were isolated,34strains were H1N1subtype,7strains were H3N2subtype,3strains were B type.2strains in2010to2011,33strains in2011to2012,9strains in2012. All antigenic drift of influenza hadn"d occurred.3. Monitoring of outbreak4outbreaks of influenza were reported from2010to2012,2outbreaks were reported in Rencheng District,1outbreaks was reported in Jiaxiang country,1outbreaks was reported in Qufu county.3of that occurred in schools,1of that occurred in village. B type was the main type.360ILI cases occurred in the outbreak, with97.35%o of attack rate ranged from16.67%o to256.72%o,3698people were affected.4. Evaluation of monitoring quality Rate of average report timeliness was92.48%, zero rate was2.45%. Timeliness of inspection was62.63%, coincidence rate was86.25%in Jining No.1people’s hospital. Timeliness of inspection was62.44%, coincidence rate was95%in Downtown land maternal and child care service centre. The rate of positive separation are less than10%,which were not up to the national standards from2010to2012.4the outbreak report timely, specimen collection qualified, disposal basic norms, but there were significant differences among attack rates and popular intensity.Conclusions and Suggestions 1.Conclusions Influenza monitoring system was relatively perfect and systematic according to the national influenza surveillance solution (2010), and began working in ILI report, virus isolation and outbreak monitoring treatment, which has been basically in normal operation, but there were monitoring the quality of the work in decline, lack of report, the omission of phenomenon, flu viruses isolated positive rate is low, the flu monitoring network management and quality control need to improve, enhance network resource construction and teachers training and so on, to perfect the network operation effect.2. SuggestionsFirstly,4sentinel influenza surveillance hospitals should set reasonable departments, made a serious commitment to outpatient case registration and reporting, specimen collection and transport, and ensure the completion of annual monitoring work.Secondly, strengthening the standardized training for network and medical institutions professionals&technical can improve the monitoring report, specimen collection and laboratory testing skills. The communication between CDC and sentinel influenza surveillance hospitals was advanced and the problems, which was able to be solved in time.Thirdly, it is necessary to reinforce epidemic surveillance to prevent spread of the disease especially for primary and secondary schools.Fourthly, Continue perfect the management of the sentinel influenza surveillance hospitals and netlab with inspect the system, ensure personnel, funds, training, equipment, reagents material etc in place in time, can enhance staffs enthusiasm, guarantee monitor quantity and the quality, to ensure it work smoothly.
