The age of patients admitted to intensive care units (ICUs) has witnessed a significant increase in the last decades. Recent statistics reveal that ten to fifteen percent of ICU-admitted patients are older than 80 years, with one percent ageing at least 90 years [1–4]. Given the ongoing rise of individuals surpassing 90 years in the global population, the upward trajectory in ICU admissions for these individuals is also expected to persist [5]. Importantly, nonagenarians (those aged between 90 and 99 years) exhibit distinct characteristics that necessitate tailored care, especially within the ICU [6–8].
