As life expectancy increases and birth rates decline, the geriatric population continues to grow faster than any other age group. Aging is characterized by a progressive physiologic decline that promotes the onset of functional limitation and disability. With the increasing geriatric population, more elderly patients are presenting to emergency departments after trauma, and intensive care units are being met with increasing demand. Rehabilitation is critical in improving quality of life by maximizing physical, cognitive, and psychological recovery from injury or disease.The importance of evaluating and adjusting the nutritional state of critically ill patients has become a core principle of care. This article focuses on tools for the nutritional assessment of geriatric intensive care unit patients, including a review of imaging and other standardized techniques for evaluation of muscle mass, an indicator of malnutrition and sarcopenia. It concludes with a discussion of the interplay of malnutrition, reduced muscle mass/sarcopenia, and frailty. The goal of this multidimensional assessment is to identify those at risk and thereby initiate interventions to improve outcomes.Dementia is a terminal illness that leads to progressive cognitive and functional decline. As the elderly population grows, the incidence of dementia in hospitalized older adults increases and is associated with poor short-term and long-term outcomes. Delirium is associated with an accelerated cognitive decline in hospitalized patients with dementia. The first step in the management of dementia is accurate and early diagnosis. Evidence-based management guidelines in the setting of critical illness and dementia are lacking. The cornerstone of management is defining goals of care early in the course of hospitalization and using palliative care and hospice when deemed appropriate.Patients with cancer are at high risk of developing acute critical illness requiring intensive care unit (ICU) admission. Critically ill patients with cancer have complex medical needs that can best be served by a multidisciplinary ICU care team. This article provides an overview of the current state-of-the-art in multidisciplinary care for critically ill patients with cancer. Better integration of multidisciplinary critical care into the continuum of care for patients with cancer offers the prospect of further improvements in the outcomes of patients with cancer.Older adults are particularly vulnerable during the Coronavirus disease 2019 (COVID-19) pandemic, because higher age increases risk for both delirium and COVID-19-related death. Despite the health care system limitations and the clinical challenges of the pandemic, delirium screening and management remains an evidence-based cornerstone of critical care. This article discusses practical recommendations for delirium screening in the COVID-19 pandemic era, tips for training health care workers in delirium screening, validated tools for detecting delirium in critically ill older adults, and approaches to special populations of older adults (eg, sensory impairment, dementia, acute neurologic injury).The number of older adults with cancer is growing in the United States, and there is a relative paucity of data relating the presence of frailty with its outcomes of interest. The authors present the surgical oncology, radiation oncology, and medical oncology literature with respect to the presence of frailty in older adults with cancer. BAL-0028 More research is needed to understand how the presence of frailty should be used by surgical, radiation, and medical oncologists to guide patient counseling and treatment planning.Older patients experience a decline in their physiologic reserves as well as chronic low-grade inflammation named "inflammaging." Both of these contribute significantly to aging-related factors that alter the acute, subacute, and chronic response of these patients to critical illness, such as sepsis. Unfortunately, this altered response to stressors can lead to chronic critical illness followed by dismal outcomes and death. The primary goal of this review is to briefly highlight age-specific changes in physiologic systems majorly affected in critical illness, especially because it pertains to sepsis and trauma, which can lead to chronic critical illness and describe implications in clinical management.Elderly patients who are critically ill have unique challenges that must be considered when attempting to prognosticate survival and determine expectations for physical rehabilitation and meaningful recovery. Furthermore, frail elderly patients present unique rehabilitation and clinical challenges when suffering from critical illness. There are multiple symptoms and syndromes that affect morbidity and mortality of elderly patients who require intensive care unit management including delirium, dementia, pain, and constipation. Rehabilitation goals should be based on patient values, clinical course, and functional status. Patients and families need accurate prognostic information to choose the appropriate level of care needed after critical illness.End-of-life care of critically ill adult patients with advanced or incurable cancers is imbued with major ethical challenges. Oncologists, hospitalists, and intensivists can inadvertently subjugate themselves to the perceived powers of autonomous patients. Therapeutic illusion and poor insight by surrogates in physicians' ability to offer accurate prognosis, missed opportunities and miscommunication by clinicians, and lack of systematic or protocolized approach represent important barriers to high-quality palliative care. Enhanced collaboration, models that allow clinicians and surrogates to share the burdens of decision, and institutional support for early integration of palliative care can foster an ethical climate.Cancer remains a leading cause of morbidity and mortality. Advances in cancer screening, early detection, targeted therapies, and supportive care have led to improvements in outcomes and quality of life. The rapid increase in novel cancer therapies can cause life-threatening adverse events. The need for intensive care unit (ICU) care is projected to increase. Until 2 decades ago, cancer diagnosis often precluded ICU admission. Recently, substantial cancer survival has been achieved; therefore, ICU denial is not recommended. ICU resources are limited and expensive; hence, appropriate utilization is needed. This review focuses on triage and prognosis in critically ill cancer patients requiring ICU admission.
