Factors that influence intensive care admission decisions for older people: A systematic review.

BACKGROUND: The population worldwide is rapidly ageing, and demand for intensive care is increasing. People aged 85 years and above, known as the oldest old, are particularly vulnerable to critical illness owing to the physiological effects of ageing. Evidence surrounding admission of the oldest old to the intensive care is limited. OBJECTIVE: The objective of this study was to systematically and comprehensively review and synthesise the published research investigating factors that influence decisions to admit the oldest old to the intensive care unit. METHOD: This was a systematic review and narrative synthesis. Following a comprehensive search of CINAHL, Embase, and Medline databases, peer-reviewed primary research articles examining factors associated with admission or refusal to admit the oldest old to intensive care were selected. Data were extracted into tables and narratively synthesised. RESULTS: Six studies met the inclusion criteria. Three studies identified factors associated with admission such as greater premorbid self-sufficiency, patient preferences, alignment between patient and physicians' goals of treatment, age less than 85 years, and absence of cancer, or previous intensive care admission. Factors associated with refusal to admit were identified in all six studies and included limited or no bed availability, level of ICU physician experience, patients being deemed too ill or too well to benefit, and older age. CONCLUSIONS: Published research investigating decision-making about admission or refusal to admit the oldest old to the intensive care unit is scant. The ageing population and increasing demand for intensive care unit resources has amplified the need for greater understanding of factors that influence decisions to admit or refuse admission of the oldest old to the intensive care unit. Such knowledge may inform guidelines regarding complex practice decisions about admission of the oldest old to an intensive care unit. Such guidelines would ensure the specialty needs of this population are considered and would reduce admission decisions that might disadvantage older people.

Age in the Time of COVID-19: An Ethical Analysis.

Despite using a myriad of methods to combat the spread of COVID-19, the healthcare systems (especially the intensive care units) have been overwhelmed, showing an outpaced capacity of available beds and ventilators. Choosing the right criteria to allocate the scarce ICU seems very challenging, being necessary a rapid, uncomplicated and universally accepted tool for patients' triage regarding access to lifesaving resources; one such criterion, which generates intense debates, is age. Under certain circumstances, it might seem appropriate to choose to treat a young over an old patient. The main advantage of this approach is the potential for long-term survival, implying an equal right to reach an advanced age. Many authors have given moral reasons to support it, mainly based on utilitarian ethics or on distributive justice. However, there are numerous counterarguments to this approach, which we will summarize in this article. We will show that age should never be used as a unique criterion for withholding/not initiating life-saving procedures, even in pandemics or cases in which healthcare resources are extremely scarce. This approach is based on fundamental Codes of Ethics, such as the WMA Code of Ethics or the Oath of Hippocrates and all physicians treating patients should obey them.
