“…Existing studies often refer to age as a single risk factor for delirium, but the old patient group is rarely studied as a singular group for clinical outcome analysis and the fi ndings are inconsistent. [30,31] We found that aging was an independent risk factor for both ICU and hospital deaths even after controlling APACHE score and ICU treatment factors. This is in accordance with previous studies which have found that older patients (≥65 years) were susceptible to have physical and cognitive declines following critical illness, [32] sudden clinical deterioration with a change in goals of care, [33] and limitation of treatment.…”

BACKGROUND: Delirium in patients in intensive care units (ICUs) is an acute disturbance and fl uctuation of cognition and consciousness. Though increasing age has been found to be related to ICU delirium, there is limited evidence of the effect of age on delirium outcomes. The aim of this study is to investigate the relationship between age categories and outcomes among ICU delirium patients. METHODS: Data were extracted from the electronic ICU (eICU) Collaborative Research Database with records from 3,931 patients with delirium. Patients were classifi ed into non-aged (<65 years), youngold (65-74 years), middle-old (75-84 years), and very-old (≥85 years) groups. A Cox regression model was built to examine the role of age in death in ICU and in hospital after controlling covariates. RESULTS: The sample included 1,667 (42.4%) non-aged, 891 (22.7%) young-old, 848 (21.6%) middle-old, and 525 (13.3%) very-old patients. The ICU mortality rate was 8.3% and the hospital mortality rate was 15.4%. Compared with the non-aged group, the elderly patients (≥65 yeras) had higher mortality at ICU discharge (χ 2 =13.726, P=0.001) and hospital discharge (χ 2 =56.347, P<0.001). The Cox regression analysis showed that age was an independent risk factor for death at ICU discharge (hazard ratio [HR]=1.502, 1.675, 1.840, 95% confi dence interval [CI] 1.138-1.983, 1.250-2.244, 1.260-2.687; P=0.004, 0.001, 0.002 for the young-, middle-and very-old group, respectively) as well as death at hospital discharge (HR=1.801, 2.036, 2.642, 95% CI 1.454-2.230, 1.638-2.530, 2.047-3.409; all P<0.001). CONCLUSIONS: The risks of death in the ICU and hospital increase with age among delirious patients.

“…The association of weaning groups with 1-year mortality was assessed with the log-rank test and visualized with Kaplan-Meier plots. Multivariable Cox regression analysis was performed to assess this association, adjusting for a priori-identified confounders, including age (19, 20), reason for admission (21), body mass index (BMI) (22), APACHE ΙΙ score (21), SOFA score (21), and sepsis (23). The proportional hazard assumption for the weaning groups was checked with the Schoenfeld residuals, and if violated, the variable was entered as a time-dependent covariate.…”

OBJECTIVES:The weaning according to a new definition (WIND) classification groups mechanically ventilated (MV) patients into "short weaning, " "difficult weaning, " "prolonged weaning, " and "no weaning. " The aims of the study were: 1) to describe the weaning group distribution, 2) to evaluate if "short weaning" patients can be divided into groups with distinct characteristics and outcomes depending on the MV duration, and 3) to study 1-year outcomes related to weaning groups.

“…The number of hospitalizations among the elderly in public hospitals is growing in all hospital sectors, especially in Intensive Care Units (ICUs), where elderly patients 60 years or more represent between 42% and 52% of hospitalizations and have a poor prognosis compared to younger patients. [4] In Australia and New Zealand, it is estimated that the rate of people aged at 80 or older admitted to ICUs increase by 72% in 2050. This growth imposes major implications on health resources, the need for expansion of ICU capacity and the need to care for this population.…”

“…Also, knowing the factors associated with admission and discharge of elderly in Intensive Care Units is essential to direct and give focus to health actions. [4] Thus, this paper studied the factors associated with admission and discharge of elderly patients 60 years or more in intensive care units and has the objective to analyze which factors are associated with admission and discharge of elderly patients in these units.…”

Objective: To analyze the factors related to hospitalization of elderly in Intensive Care Unit. Method: Integrative literature review performed in BDENF, Medline and ScienceDirect databases. We selected 11 articles published from 2008 to 2015 that met the inclusion criteria. Data were processed in IRAMUTEC software. Results: Results are presented in 05 classes, as follows: Class 1: Use of systems to assess the level of severity for ICU patients; Class 2: Length of stay of elderly in ICUs; Class 3: Old age and underlying diseases in patients treated in ICUs; Class 4: The main clinical outcomes of admission of elderly in ICU; Class 5: The care provided to elderly in the ICU. Conclusion: The Simplified Acute Physiology Score (SAPS II) model was the most used in elderly patients admitted to intensive care units, the prolonged length of stay is associated with worse prognosis, especially in patients with underlying diseases, and the postoperative period is the main cause of admission.
