Medical records of 166 patients hospitalized for pneumonia were analyzed to determine the relationship between patient age and the clinical features and outcome. Fifty-seven patients were older than 79 years, 55 were 60 to 79 years, and 54 were younger than 60 years. The three groups had similar heart rates, respiratory rates, arterial/alveolar oxygen tension ratios, leukocyte counts, body temperatures, frequency of multilobe pneumonias, and incidence and types of bacterial pathogens. Mortality was 0, 6, and 11% in decades 5 through 7 and rose gradually with age, being 11, 13, and 17% in decades 8 through 10. Hospital stay was 5.7 days in those less than 60 years of age, 9.8 days in those aged 60 to 79, and 11.3 days in those older than 79 years. Although elderly adults are hospitalized frequently for treatment of pneumonia, an individual episode of pneumonia requiring hospitalization in the elderly patient is of equivalent severity to that in younger patients and has similar clinical features and outcome.
对166例因肺炎住院患者的病历进行分析，以确定患者年龄与临床特征及预后之间的关系。57例患者年龄大于79岁，55例年龄在60至79岁之间，54例年龄小于60岁。三组患者的心率、呼吸频率、动脉/肺泡氧分压比值、白细胞计数、体温、多叶肺炎发生率以及细菌病原体的发生率和类型相似。5至7个十年的死亡率分别为0%、6%和11%，并随年龄逐渐上升，8至10个十年的死亡率分别为11%、13%和17%。年龄小于60岁的患者住院时间为5.7天，60至79岁的患者为9.8天，年龄大于79岁的患者为11.3天。尽管老年人因肺炎治疗而频繁住院，但老年患者因肺炎需要住院的单次发作与年轻患者的严重程度相当，且具有相似的临床特征和预后。
