2015—2016年中国住院严重急性呼吸道感染病例监测系统数据质量评估

Evaluation on data quality of severe acute respiratory infection sentinel surveillance system in China,2015-2016

目的了解我国现行住院严重急性呼吸道感染(SARI)病例监测系统的数据质量,优化监测系统。方法从全国SARI病例监测系统中导出2015年7月6日至2016年7月10日期间报告的所有SARI病例信息,分析登记一览表和病例调查表信息完整性、病例纳入的准确性、及时性(病例登记、标本采集、标本送检)、监测科室代表性。结果调查期间全国共报告SARI病例11 091例,病例登记一览表信息完整率为83.4%,调查表信息完整率为95.6%;12.5%报告病例不符合SARI监测病例定义,不符合的主要原因为病例无咳嗽症状(81.1%);病例登记、标本采集以及标本送检的及时率分别为81.4%、84.7%和76.4%;报告SARI病例有99.6%来自监测方案推荐的监测科室。结论我国现行SARI病例监测系统数据质量整体良好,但病例登记一览表信息的完整性、报告SARI病例的准确性、标本送检的及时率有待提高,建议将病例登记一览表中易漏报信息设为必填项,加强对病例定义培训,并针对标本送检率低的原因进一步开展调查。

Objective To understand the data quality of severe acute respiratory infection（ SARI） sentinel surveillance system in China and provide evidence for the optimization of the system. Methods The data of SARI cases data from July 6^th 2015 to July 10^th 2016 were collected from the sentinel surveillance system. The completeness of registration information and questionnaire,accuracy of case inclusion and timeliness of case registration,specimen collection and transportation. Results A total of 11 091 SARI cases were reported. The completeness rates of registration information and questionnaire were 83. 4%and 95. 6%,respectively. Among the reported cases,12. 5% didn＇t meet the case definition,and the main reason was lack of cough symptoms（ 81. 1%）. The timeliness rates of cases registration,specimen collection and specimen transportation were 81. 4%,84. 7% and 76. 4%,respectively. Up to 99. 6% of the cases were reported from the sentinel departments.Conclusion The data quality of China＇s SARI sentinel surveillance system was good,but some efforts are still needed to improve the completeness of registration information,accuracy of reported case and timeliness of specimen transportation. It is suggested to fill all the information items in the registration form,strengthen the professional training about case definition and find the reason for the low timeliness of specimen transportation.
