一般而言,老年人不论因何病住院,随后患肺炎的危险都会有所增加。而对因肺炎住院的病人重患肺炎的危险是否更大尚无评价。为此,本文作者对573例进行了回顾研究。病人和方法选择1987～1988年573例成年病人(≥18岁),其中241例出院诊断为肺炎(A 组),198例胃肠感染、48例肾脏感染、86例丹毒(后三类统归 B 组)。出院后对病人随访,将他们分为18～49、50～64、65～85和85岁以上四个年龄组,评估这些患者到1990年10月31日止因肺炎重新住院及死亡的情况。
In general, the risk of subsequent pneumonia is increased in elderly people regardless of their hospitalization. However, there is no comment on whether the risk of severe pneumonia in patients hospitalized with pneumonia is greater. To this end, the author of the 573 cases were reviewed. Patients and Methods 573 adult patients (≥18 years) from 1987 to 1988 were selected, 241 of whom were discharged as pneumonia (group A), 198 with gastrointestinal infection, 48 with kidney disease, and 86 with erysipelas Group B). After discharge from the hospital, patients were followed up and divided into four age groups of 18-49, 50-64, 65-85 and 85 years old and above. The patients were re-admitted to hospital and died of pneumonia as of October 31, 1990.
