Background: Dysphagia, as a geriatric syndrome, is prevalent in the intensive care unit (ICU). Malnutrition resulting from swallowing disorders is likely to correlate with adverse ICU outcomes, including delirium, thereby escalating the costs of care and hospitalization. However, malnutrition has not received the attention it deserves in ICU clinical nursing practice. As two preventable and correctable conditions—malnutrition and delirium—the advantages of early identification and intervention are substantial. Exploring the relationship between malnutrition and delirium, starting from the high‐risk group of elderly patients with swallowing difficulties in the ICU, will aid us in managing patients promptly and effectively. Aim: To investigate the relationship between malnutrition and the incidence of delirium in elderly patients with dysphagia in the ICU. Study Design: This is a retrospective study. Data for this study were obtained from the Medical Information Mart for Intensive Care‐IV. All 2273 patients included were dysphagia older patients over 65 years of age admitted to the ICU, and logistic regression was used to explore the relationship between malnutrition and delirium. We also used propensity score matching (PSM) for sensitivity analysis. Results: Among the included patients with swallowing difficulties, 13% individuals (297/2273) exhibited malnutrition, with a delirium incidence rate of 55.9% (166/297). In the non‐malnutrition group (1976/2273), the delirium incidence rate is 35.6% (704/1976). After adjusting for 31 covariates, multifactorial logistic regression showed that malnutrition was significantly positively associated with the incidence of delirium in elderly dysphagic patients in the ICU (adjusted odds ratio (OR) = 1.96, 95% confidence interval (CI) = 1.47–2.62). The results remained stable after analysis by PSM. Conclusion: Malnutrition was significantly positively associated with the incidence of delirium in elderly dysphagic patients in the ICU. Malnutrition should be given adequate attention in the ICU. Relevance to Clinical Practice: ICU nurses should pay particular attention to malnutrition, especially among the high‐prevalence group of patients with dysphagia. Early identification and nutritional intervention for these patients may help reduce the costs of care and health care expenditures. [ABSTRACT FROM AUTHOR]

Background: Atrial fibrillation (AF) and frailty are significant global public health problems associated with advancing age. However, the relationship between frailty and older patients with AF in the intensive care unit (ICU) has not been thoroughly investigated. This study aimed to investigate whether the hospital frailty risk score (HFRS) is associated with adverse outcomes in older patients with AF in the ICU., Methods: This was the first retrospective analysis of older patients with AF admitted to the ICU between 2008 and 2019 at a tertiary academic medical center in Boston. The HFRS was used to measure frailty severity. The outcomes of interest were in-hospital and 30-day mortality and the incidence of sepsis and ischemic stroke., Results: There were 7,792 participants aged approximately 80 years, almost half (44.9%) of whom were female. Among this group, 2,876 individuals were identified as non-frail, while 4,916 were classified as frail. The analysis revealed a significantly greater incidence of in-hospital (18.8% compared to 7.6%) and 30-day mortality (24.5% versus 12.3%) in the frail group. After accounting for potential confounding factors, a multivariate Cox proportional hazards regression analysis revealed that frail participants had a 1.56-fold greater risk of mortality within 30 days (95% CI = 1.38-1.76, p < 0.001)., Conclusions: Frailty is an independent risk factor for adverse outcomes in older patients with AF admitted to the ICU. Therefore, prioritizing frailty assessment and implementing specific intervention strategies to improve prognostic outcomes are recommended., Competing Interests: Competing interests The authors declare that they have no competing interests.
