目的评价西安市参保职工接种流感疫苗的成本效益。方法选择西安东方集团有限公司为研究现场,对该集团公司全部12109名参保职工,用随机整群抽样方法,抽取2949人,进行问卷调查。样本人群中,接种流感疫苗1900人、未接种流感疫苗1049人。采用历史性队列研究方法,对接种组和对照组同时进行回顾性调查。重点调查流感疫苗接种后12个月内,两组人群呼吸系统、心脑血管疾病及其他慢性病患病情况及医疗服务利用情况。结果接种组呼吸系统疾病和心脑血管疾病粗住院率分别为0.51%和1.64%,较对照组降低了68.90%和56.05%。疫苗接种后第3、4个月接种组和对照组粗住院率分别为0.62%、0.80%和0.28%、1.00%。65岁及以上年龄接种组粗住院率较对照组低53.59%。2005年度西安市参保人群接种流感疫苗降低住院率产生的效益成本比标化后为6.48。结论西安市参保职工接种流感疫苗具有较高的成本效益,产生良好成本效益的原因是,明显降低了接种组参保中老年职工呼吸系统和心脑血管疾病住院率。
