Abstract：
BACKGROUND: Although older individuals are prone to pneumonia relapse, little real-world evidence is available on the main factors contributing to pneumonia recurrence. This study assessed the impact of patients\' lifestyles on hospital readmission due to pneumonia recurrence.
METHODS: We retrospectively included consecutive patients (aged ≥65 years) who were admitted for community-onset pneumonia. A binary or multiple-choice postal questionnaire survey on lifestyles after hospitalization was conducted to identify the factors associated with readmission due to pneumonia recurrence.
RESULTS: Of 117 patients who responded to the questionnaires, 89 were included in the analyses after excluding 28 patients who died within 1 year of discharge. Twenty-four of 89 (27%) patients were readmitted to the hospital for pneumonia within 1 year of discharge. Multivariate analysis revealed that cerebrovascular disease (odds ratio [OR], 3.912; 95% confidence interval [CI], 1.104-13.861; p = 0.035) and need of assistance at mealtime (OR, 2.225; 95% CI, 1.182-4.186; p = 0.013) were significantly associated with readmission due to pneumonia recurrence. Oral care and mealtime body position were not associated with readmission.
CONCLUSIONS: Host factors, not patients\' lifestyles such as oral care and body position, mainly contribute to the development of pneumonia among older people. These results should be considered risk factors for readmission by medical workers and family members.

摘要：
背景：虽然老年人容易肺炎复发，关于导致肺炎复发的主要因素，真实世界的证据很少。这项研究评估了患者的生活方式对肺炎复发后再次入院的影响。
方法：我们回顾性纳入了因社区肺炎入院的连续患者（年龄≥65岁）。对住院后的生活方式进行了二元或多项选择的邮政问卷调查，以确定与因肺炎复发而再次入院相关的因素。
结果：在回答问卷的117名患者中，在排除28例出院后1年内死亡的患者后，89例纳入分析。89名患者中有24名（27％）在出院后1年内因肺炎再次入院。多因素分析显示脑血管病(比值比[OR]，3.912；95%置信区间[CI]，1.104-13.861；p=0.035)和用餐时需要帮助(OR，2.225；95%CI，1.182-4.186；p=0.013）与肺炎复发导致的再入院显着相关。口腔护理和用餐时体位与再次入院无关。
结论：宿主因素，不是患者的生活方式，如口腔护理和身体姿势，主要是导致老年人肺炎的发展。这些结果应被视为医务人员和家庭成员再次入院的危险因素。
