摘要目的:探究FilmArray检测在儿童急性下呼吸道感染中的应用价值并进行卫生经济学分析。方法:选取2016年12月1日至2017年11月30日入住我院的急性下呼吸道感染患儿1 380例，部分患儿(FilmArray组)应用FilmArray检测呼吸道感染病原体，其他患儿(对照组)应用呼吸道病毒7项抗原检测，金胶体法检测甲型流感、乙型流感和肺炎支原体抗体检测，排除存在基础疾病者，并采用倾向得分匹配法(Propensity Score Matching)平衡FilmArray组与对照组间基本资料不均衡的变量，得到匹配者。分析病原体检出情况，比较组间临床指标、抗感染药物使用情况及住院相关费用。结果:FilmArray组检测的阳性率明显高于对照组(86.88%比45.91%)。FilmArray组检出最多的病原体为腺病毒(39例)，其次为鼻病毒(34例)、副流感病毒(30例)，检出百日咳鲍特菌阳性9例。FilmArray组住院时间短于对照组[(8.89±6.23)d比(11.51±4.43)d]，抗生素使用时间短[(7.09±5.67)d比(10.00±3.39)d]。FilmArray组比对照组抗生素使用费用更少，住院时间更短，应用FilmArray检测平均每人可节约住院费用近2 000元。结论:FilmArray检测应用于儿童急性下呼吸道感染能快速、准确地明确多种病毒、细菌及非典型病原体感染，更好地指导抗感染药物使用。FilmArray检测的应用缩短了患儿的平均住院天数，增加了医疗资源的利用效率，降低患儿家庭的医疗成本和间接经济损失，带来卫生经济学获益。

abstractsObjective:To explore the application value of FilmArray detection in children with acute lower respiratory tract infection and conduct economics analysis.Methods:From December 1, 2016 to November 30, 2017, 1 380 patients were enrolled in our study.Some children(FilmArray group) were tested for respiratory pathogens with FilmArray, while others (control group) were tested by 7-box antigen test of respiratory virus, gold colloid test of influenza and mycoplasma antibody.Those with underlying diseases were excluded.A total of 160 cases in the FilmArray group and 160 cases in the control group were obtained with tendency score matching method.The physical examination of pathogens, clinical indicators, usage of anti-infective drugs and hospitalization related costs were compared.Results:The positive rate of FilmArray test was significantly higher than that in control group (86.88% vs. 45.91%). The most common pathogens detected by FilmArray were adenovirus(39 cases), rhinovirus(34 cases), and parainfluenza virus(30 cases). In the FilmArray group, nine cases were positive for botulinum pertussis, accounting for 5.6% of the total.The hospitalization time of FilmArray group was shorter than that in control group [(8.89±6.23 days vs.(11.51±14.43)days]. In FilmArray group, the antibiotics were used for a shorter time, and 18 children did not use antibiotics during hospitalization.Compared with the control group, the hospitalization cost had no significant difference in the FilmArray group, but the antibiotic cost was less, as well as hospitalization time was shorter.The average hospitalization cost saved by using the FilmArray test was nearly 2 000 yuan per person. Conclusion:The application of FilmArray detection in children with acute lower respiratory tract infection can quickly and accurately identify a various infections of virus, bacteria and atypical pathogen, which guides using anti-infective drugs more reasonably.The application of FilmArray detection shortens the average hospitalization days of children, increases the utilization efficiency of medical resources, and reduces the medical cost and indirect economic loss of children’s families, which has certain economics significance.
