目的:分析疑似预防接种异常反应(AEFI)的发生特征,评价AEFI监测系统运行情况,为开展疫苗安全性的评价提供具有科学性和可比性的资料。方法:收集2011年12月-2014年11月昆明市东川区中医医院AEFI监测系统报告的个案数据,采用描述性方法进行流行病学分析。结果:我院共报告AEFI 27例,<2岁病例占62.96%,男女性比例为1.45:1,主要集中在3~7月份;国家免疫规划(NIP)疫苗接种后发生的AEFI占67.42%,病例以一般反应为主,27例AEFI中不良反应25例,占92.59%,AEFI疫苗分布中以无细胞百白破疫苗和麻风腮疫苗为主,分别占38.91%、28.64%;反应发生在疫苗接种后<1d,占83.47%,临床危害以发热为主,占53.52%;异常反应中以过敏性皮疹为主,占18.52%;27例AEFI中有26例治愈或好转,占96.30%,1例偶合症,占3.70%,全院均有AEFI数据报告,48 h及时报告率为97.36%,48 h及时调查率为84.21%。结论:我院AEFI监测系统总体运转情况正常,但监测质量还需进一步提高。
OBJECTIVE: To analyze the occurrence characteristics of suspected AEFI, evaluate the operation of AEFI monitoring system and provide scientific and comparable data for the evaluation of vaccine safety. Methods: The data collected from AEFI monitoring system of Dongchuan District Hospital of Traditional Chinese Medicine, Kunming from December 2011 to November 2014 were collected, and the descriptive method was used for epidemiological analysis. Results: AEFI was reported in 27 cases in our hospital. The incidence of AEFI was 62.96% in cases of 2 years old and 1.45: 1 in men and women, mainly in March to July. AEFI accounted for 67.42% after NIP vaccination, Among the 27 cases, 25 cases (92.59%) were adverse reactions in AEFI and 38.91% and 28.64% in AEFI vaccine, respectively. The reaction occurred in the vaccine Inoculation <1d, accounting for 83.47%, clinical harm to fever, accounting for 53.52%; an allergic reaction to allergic rash, accounting for 18.52%; 27 cases of AEFI cured or improved in 26 cases, accounting for 96.30%, 1 Cases of complications, accounting for 3.70%, the hospital have AEFI data report, 48 h timely reporting rate was 97.36%, 48 h timely investigation rate was 84.21%. Conclusion: The overall operation of AEFI monitoring system in our hospital is normal, but the quality of monitoring needs to be further improved.
