Background Age is a significant consideration for intensive care unit (ICU) admission. However, the reported associations between increasing age and mortality vary across studies, and data in the local context of Malaysia are lacking. The objective of the present study was to determine the impact of increasing age on ICU mortality.
Methods A retrospective cohort study of ICU patients was conducted between January 2020 and November 2023 at a university hospital in Malaysia. Patients were classified into two categories according to age (years) and into four groups according to National Library of Medicine Medical Subject Headings (MeSH): young adult (19–24), adult (25–44), middle age (45–64), and elderly (≥65). The Cochran-Armitage test for trend and Cox proportional hazards regression analyses were performed to evaluate the impact of increasing age on ICU mortality.
Results A total of 1,661 patients was analyzed. The Cochran-Armitage test showed a significant positive association between ICU mortality rate and age group (Z=−4.86, P<0.01) or MeSH category (Z=−5.36, P<0.01). After adjusting for other confounders, the strongest predictor for ICU mortality in the Cox proportional hazards regression analyses was age, with the elderly age group having the highest adjusted hazard ratio of 4.777 (95% CI, 1.128–20.231; P=0.03).
Conclusions Age had a significant impact on ICU mortality in our cohort of critically ill patients.

Background Aging is a significant issue worldwide, and Korea is one of the most rapidly aging countries. Along with the demographic transition, the age structure of intensive care unit (ICU) patients changes as well.
Methods The aim of this study was to analyze the change in age distribution of the ICU patients over the last 10 years and its effect on clinical outcomes. Single-center, retrospective analysis of all patients aged ≥18 years admitted to either the medical or surgical ICU at St. Paul’s Hospital, The Catholic University of Korea, between January 2005 and December 2014 was conducted. For clinical outcome, in-hospital mortality, duration of ICU stay, and hospital stay were analyzed. Cost analysis was performed to show the economic burden of each age strata.
Results A total of 10,366 ICU patients were admitted to the chosen ICUs during the study period. The proportion of elderly patients aged ≥65 years increased from 47.9% in 2005 to 63.7% in 2014, and the proportion of the very elderly patients aged ≥80 years increased from 12.8% to 20.7%. However, this increased proportion of elderly patients did not lead to increased in-hospital mortality. The percent of ICU treatment days attributable to elderly patients increased from 51.1% in year 2005 to 64.0% in 2014. The elderly ICU patients were associated with higher in-hospital mortality compared to younger age groups.
Conclusions The proportion of elderly patients admitted to ICUs increased over the last decade. However, overall in-hospital mortality has not increased during the same period.

BACKGROUND Extracorporeal membrane oxygenation (ECMO) strategy is proposed to reduce the ventilator-induced lung injury in acute respiratory distress syndrome (ARDS). As ECMO use has increased, a number of studies on prognostic factors have been published. Age is estimated to be an important prognostic factor. However, clinical evidences about ECMO use in elderly patients are limited. Therefore, we investigated clinical courses and outcomes of ECMO in elderly patients with ARDS. METHODS We reviewed medical records of patients with severe ARDS who required ECMO support. Study patients were classified into an elderly group (> or = 65 years) and a non-elderly group (< 65 years). Baseline characteristics, ECMO related outcomes and associated factors were retrospectively analyzed according to group. RESULTS From February 2011 to June 2013, a total of 31 patients with severe ARDS were treated with ECMO. Overall, 14 (45.2%) were weaned from ECMO, 9 (29.0%) survived to the general ward and 7 (22.6%) survived to discharge. Among the 18 elderly group patients, 7 (38.9%) were weaned from ECMO, 4 (22.2%) were survived to the general ward and 2 (11.1%) were survived to discharge. Overall intensive care unit survival was inversely correlated with concomitant acute kidney injury or septic shock. CONCLUSIONS In this study, ECMO outcome was poor in severe ARDS patients aged over 65 years. Therefore, the routine use of ECMO in elderly patients with severe ARDS is not warranted except in highly selective cases.

Background As the population ages, the elderly will constitute a prominent proportion of trauma patients. The elderly suffer more severe outcomes from injuries compared with the young. In this study, we examined the relationship between mortality and complications with age.
Methods This study was a retrospective review of 256 major trauma patients (Injury Severity Score > 15) admitted to an emergency center over a two- year period. Age-dependent mortality and complications were evaluated.
Results Of 256 patients, 209 (81.6%) were male and the mean age was 47.2 years. There was a trend between increasing age and increasing mortality, but this was not statistically significant. Increasing age was correlated with frequency of complications.
Conclusions Age was confirmed to be an independent predictor of mortality in major trauma. We documented that elderly trauma patients suffer from complications more frequently compared with their younger counterparts. Appropriate and specific triage and management guidelines for elderly trauma patients are needed.
