A retrospective, cross-sectional study of children with suspected urinary tract infections (UTIs) 3 months to 18 years of age who had a urinalysis and urine culture (UC) during an emergency department (ED) visit between 2019 and 2020 was performed. Chi-square, Fisher exact, and independent samples tests were used as appropriate. Median age was 6.6 years (interquartile range = 3.3-12.4). Urinalysis positivity was 92.8%, of which 81.9% of children were prescribed a first-line antibiotic. First-line antibiotic use was 82.7%. Positive UC rate was 84.7%, with 84% receiving a first-line antibiotic ( = .025). The correlation between a positive urinalysis and a positive UC was 80.8% ( < .001). Change of antibiotics based on the uropathogen of positive UCs was 6.3% ( < .001). The urinalysis and UC guided the diagnosis and treatment of UTIs. First-line antibiotics can be safely administered in the ED and prescribed for positive urinalyses. Studies are needed to evaluate the discontinuation of antibiotics with negative UCs as part of antibiotic stewardship initiatives.
本研究回顾性分析了 2019 年至 2020 年间在急诊科就诊的疑似尿路感染(UTI)的 3 个月至 18 岁儿童的尿液分析和尿液培养(UC)结果。采用卡方检验、Fisher 确切检验和独立样本检验。中位年龄为 6.6 岁(四分位距 = 3.3-12.4)。尿分析阳性率为 92.8%,其中 81.9%的患儿开具了一线抗生素。一线抗生素使用率为 82.7%。UC 阳性率为 84.7%,其中 84%的患儿接受了一线抗生素治疗(=0.025)。尿分析阳性与 UC 阳性之间的相关性为 80.8%(<0.001)。根据 UC 阳性的病原体改变抗生素的比例为 6.3%(<0.001)。尿分析和 UC 指导了 UTI 的诊断和治疗。在急诊科可以安全地使用一线抗生素,并对尿分析阳性的患儿开具处方。需要开展研究,评估作为抗生素管理计划的一部分,对 UC 阴性的患儿停用抗生素。
