摘要
目的利用数据发掘技术分析广东省2009-2014年甲型肝炎减毒活疫苗(Hepatitis A Attenuated Live Vaccine,Hep A-L)预防接种异常反应的可疑信号。方法利用比例失衡分析(Disproportionality Analysis,DPA)频数法中的报告比值比(Reporting Odds Ratio,ROR)和比例报告比(Proportional Reporting Ratio,PRR)及贝叶斯法中的贝叶斯置信传播神经网络(Bayesian Confidence Propagation Neural Network,BCPNN)和模糊贝叶斯伽马-泊松收缩论(Empirical Bayes Gamma-Poisson Shrinker,GPS)方法,对广东省2009-2014年疑似预防接种异常反应(AEFI)信息管理系统中报告的有明确诊断的Hep A-L预防接种异常反应进行分析,检测可疑信号。结果广东省2009-2014年有8 233例明确诊断的预防接种异常反应个案参与分析,其中Hep A-L的异常反应169例,占2.05%,使用ROR和PRR分析发现7个可疑信号,使用BCPNN和GPS方法共发现2个可疑信号。4种方法发现的可疑信号主要是接种Hep A-L后过敏性休克和喉头水肿。结论过敏性休克和喉头水肿为已知的Hep A-L的预防接种异常反应,利用DPA方法发现可疑信号增高的警示,需要更严谨的流行病学方法对信号进行评估。
Objective To detect suspected signals for vaccine reactions from hepatitis A attenuated live vaccine( Hep A-L) using data mining techniques in 2009-2014 in Guangdong province. Methods We used four Disproportionality Analysis( DPA) methods,including reporting odds ratio( ROR),proportional reporting ratio( PRR),Bayesian confidence propagation neural network( BCPNN),and empirical Bayes Gamma-Poisson shrinker( GPS) to detect suspected vaccine safety signals. Data of rare vaccine reactions with clinical diagnoses related to Hep A-L in 2009-2014 were collected by Chinese National Information System for Adverse Events Following Immunization Surveillance. Results A total of 8 233 rare vaccine reactions with clinical diagnoses were reported in Guangdong from 2009 to 2014,in which 169( 2. 05%) were related to Hep A-L. Seven suspected vaccine safety signals were detected by ROR and PRR,and 2 signals were detected by BCPNN and GPS. The main suspected vaccine safety signals were anaphylactic shock and laryngeal edema. Conclusions Anaphylactic shock and laryngeal edema,known rare vaccine reactions after Hep A-L immunization,were identified as two increased suspected signals by DPA methods. These signals need to be evaluated by more rigorous epidemiological methods.
