Impact of frailty on in-hospital outcomes in nonagenarian ICU patients: a binational multicenter analysis of 8,220 cases.

Background: As global populations age, the number of nonagenarians admitted to intensive care units (ICUs) is rising. Frailty, a multidimensional syndrome marked by diminished physiological reserves, has been associated with adverse outcomes in older ICU patients. However, evidence remains limited regarding its prognostic significance in nonagenarians, who represent a unique and rapidly growing subset of critically ill patients.

Characteristics, outcomes, and complications among nonagenarian and centenarian patients admitted to the intensive care unit: a scoping review.

Introduction: Nonagenarians and centenarians are a growing and vulnerable groups of patients admitted to ICU. There is limited information on their characteristics, outcomes, and complications.

Methods: We performed a scoping review of studies focused on nonagenarians and centenarians admitted to ICU.

Characteristics, outcomes and complications among nonagenarians and centenarians admitted to intensive care: a scoping review protocol.

Introduction: Nonagenarians and centenarians, compared with other age groups, often exhibit distinct physiological characteristics and a higher prevalence of comorbidities, thus further complicating their care in intensive care unit (ICU) settings. Despite the increasing number of such patients being admitted to ICUs, comprehensive research and studies on their characteristics, outcomes and complications during their ICU stays remain lacking. This scoping review will comprehensively address the following question: What are the characteristics, outcomes, complications and mortality rates among nonagenarians and centenarians admitted to ICUs, including their preadmission health status, reasons for admission, duration of hospital/ICU stays, and factors associated with adverse outcomes? The key objectives are to map the breadth and depth of the available evidence and identify key concepts, gaps and variations in research focus.
