2007年,美国心脏协会建议仅对高危型患者使用抗生素预防感染性心内膜炎(IE)。这一变化是否影响抗生素预防的使用和IE的发病率?

研究人员在所有成人和IE中高风险的人群中率先2002年-2014年IE相关住院治疗的患者,并按年龄分层。从数据库中查询采用抗生素预防的65岁及以上患者。评估指标是抗生素预防的应用率和IE相关的住院率。

指南修订后,中度风险人群抗生素预防的应用大大减少,伴随高风险人群抗生素预防的应用量缓慢增加。在6884名18岁及以上的成人中,有7551例IE相关的住院。在65岁及以上的高风险和中度风险人群中,每季度平均IE发病率分别从872例/100万人升高至1385例/100万人和从229例/100万人升高至283/100万人。变化点分析表明,这一增长发生在2010年下半年,年龄≥65岁的成年人,美国心脏协会指南修订3年后。金黄色葡萄球菌和链球菌种类分别占所有IE的30.3%和26.4%;随着时间的推移,链球菌感染有所减少。

自在2007年美国心脏协会指南修订后,中度风险人群抗生素预防的应用明显减少,而高风险人群的变化最小。然而,指南修订后3年,中高危风险患者与IE相关的住院人数均有所增加。
