From 1996 to 2009, we analyzed changes in pneumococcal disease (PD) in Utah children aged <18 years using International Classification of Diseases, ninth revision coded hospital discharges. We observed a sustained decrease in the incidence of PD among children <5 years in 2001-2004 (-36%) and 2005-2009 (-34%) compared with 1996-2000 (pre-7-valent pneumococcal conjugate vaccine). Decreases were primarily in bacteremia, uncomplicated pneumonia, and meningitis. In contrast, significant increases in complicated pneumonia/empyema were noted in children <5 years (+95% and +85%) and 5 to 17 years (+2% and +70%). Despite decreases in PD among Utah children, complicated pneumonia/empyema has increased during the 7-valent pneumococcal conjugate vaccine era.
从 1996 年到 2009 年,我们使用国际疾病分类第九版编码的住院记录分析了犹他州<18 岁儿童中肺炎球菌病 (PD) 的变化。我们观察到,与 1996-2000 年(7 价肺炎球菌结合疫苗之前)相比,2001-2004 年(-36%)和 2005-2009 年(-34%)<5 岁儿童 PD 的发病率持续下降。下降主要发生在菌血症、单纯性肺炎和脑膜炎。相比之下,<5 岁儿童(+95%和+85%)和 5 至 17 岁儿童(+2%和+70%)中复杂性肺炎/脓胸的发生率显著增加。尽管犹他州儿童的 PD 有所减少,但在 7 价肺炎球菌结合疫苗时代,复杂性肺炎/脓胸的发病率有所增加。
