Nosocomial infections (NIs) are major health problems with morbidity and mortality. Geriatric patients require intensive care unit (ICU) admission more frequently, and serious challenges occur during treatment. We aimed to evaluate the risk factors of NI and mortality in geriatric patients admitted to the ICU.
The study was conducted between April 2018 and April 2019 in two hospitals. We prospectively recorded the data on the forms prepared according to daily ICU visits.
During the study period, 600 patients were hospitalized in the ICUs. Geriatric patients constituted 446 (74.3%) of the total number. The NI rate was 59% in adult patients and 80% in geriatric patients. The most frequent NI in geriatric patients was pneumonia (42%). Furthermore, the need for mechanical ventilation support, prolongation of hospital stay, total parenteral nutrition, and tracheostomy were statistically higher in geriatric patients with NI. The mortality rate in geriatric patients was statistically higher than in non-geriatric. We found the rates of prolonged hospitalization, NI development, malignancy, and cerebrovascular disease diagnosis significantly higher in geriatric patients than in non-geriatric patients.
NI and mortality rate are higher in geriatrics than in adult patients. Pneumonia is the most common type of NI in the ICU. Identification of risk factors regarding NI and mortality in geriatric patients in ICU will contribute to developing strategies for prevention.
医院感染（NI）是具有发病率和死亡率的主要健康问题。老年患者更频繁地需要入住重症监护病房（ICU），且在治疗期间会出现严峻挑战。我们旨在评估入住ICU的老年患者发生NI和死亡的风险因素。
该研究于2018年4月至2019年4月在两家医院进行。我们前瞻性地记录了根据每日ICU查房所准备表格上的数据。
在研究期间，600名患者入住了ICU。老年患者占总数的446名（74.3%）。成年患者的NI发生率为59%，老年患者为80%。老年患者中最常见的NI是肺炎（42%）。此外，发生NI的老年患者在机械通气支持需求、住院时间延长、全胃肠外营养和气管切开方面在统计学上更高。老年患者的死亡率在统计学上高于非老年患者。我们发现老年患者的住院时间延长、NI发生、恶性肿瘤和脑血管疾病诊断率显著高于非老年患者。
老年患者的NI和死亡率高于成年患者。肺炎是ICU中最常见的NI类型。识别ICU老年患者NI和死亡的风险因素将有助于制定预防策略。
