Critical care clinics

A substantial proportion of patients admitted to intensive care units (ICUs) are elderly patients. Based upon population growth, patient preference, and current physician practice, the number of elderly patients who receive critical care services is likely to increase substantially over the next 10 to 20 years. ⋯ Elderly patients frequently receive less aggressive care in the ICU and probably consume a lower relative proportion of ICU resources than younger patients. However, this does not necessarily result in worse outcomes.

Patients who are critically ill often develop a variety of psychiatric symptoms, which require assessment and treatment. The most common psychiatric disorder in the intensive care unit is delirium. Depressed mood and anxiety also occur, at times as discrete disorders, but more often secondary to delirium. Patients with severe mental illnesses, such as schizophrenia and bipolar affective disorder, also may become critically ill--assessment and management of these patients often requires specialized psychiatric care and is not addressed here.

COPD is a progressive disorder that is punctuated in its later stages with acute exacerbations that present a risk for respiratory failure. COPD has a disproportionate impact on older patients. ⋯ Most patients survive hospitalization in the ICU for an episode of respiratory failure. The severity of the underlying lung disease, however, underlies the poor outcomes of patients in terms of postdischarge survival and quality of life.

As the geriatric population in the United States increases and better management of chronic diseases improves survival, more elderly will become critically ill and potentially require treatment in an intensive care unit (ICU). Dan Callahan has written, "... we will live longer lives, be better sustained by medical care, in return for which our deaths in old age are more likely to be drawn out and wild." Although no health care provider hopes for a drawn out and wild death for elderly patients, many geriatric persons will succumb to disease and die after having chosen and received ICU care. Recent data suggest that, on average, 11% of Medicare recipients spend more that 7 days in the ICU within 6 months before death.

Although ALI/ARDS mortality rates have improved over the last several decades, they remain high, particularly in the geriatric patient population. Although considerable progress has been made in understanding the pathogenesis of the disease, a large number of promising treatments have proven unsuccessful. ⋯ Basic research continues to help advance our understanding of this complex syndrome and identify interesting new directions of investigation. The results of several large, randomized trials of new ventilatory and pharmacologic strategies currently underway may help identify successful methods of treating this important disease.
