The technology and expertise of critical care practice support patients through life-threatening illnesses. Most recover; some die quickly; others, however, linger--neither improving nor acutely dying, alive but with a dwindling capacity to recover from their injury or illness. Management of these patients is often dominated by the question: Is it appropriate to continue life-sustaining therapy? Patients rarely participate in these pivotal discussions because they are either too sick or too heavily sedated. ⋯ However, the potential for strained communications is mitigated if clinicians provide timely clinical and prognostic information and support the patient and family with aggressive symptom control, a comfortable setting, and continuous psychosocial support. Effective communication includes sharing the burden of decision making with family members. This shift from individual responsibility to patient-focused consensus often permits the family to understand, perhaps reluctantly and with great sadness, that intensive caring may involve letting go of life-sustaining interventions.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effects of decision aids for menorrhagia on treatment choices, health outcomes, and costs: a randomized controlled trial.
Decision aids can increase patient involvement in treatment decision making. However, questions remain regarding their effects and cost implications. ⋯ Neither intervention had an effect on health status. Providing women with information alone did not affect treatment choices; however, the addition of an interview to clarify values and elicit preferences had a significant effect on women's management and resulted in reduced costs.

Diabetic complications are the major cause of morbidity and mortality in persons with diabetes. Chronic hyperglycemia is a major initiator of diabetic microvascular complications (eg, retinopathy, neuropathy, nephropathy). ⋯ These theories can be separated into those that emphasize the toxic effects of hyperglycemia and its pathophysiological derivatives (such as oxidants, hyperosmolarity, or glycation products) on tissues directly and those that ascribe pathophysiological importance to a sustained alteration in cell signaling pathways (such as changes in phospholipids or kinases) induced by the products of glucose metabolism. This article summarizes these theories and the potential therapeutic interventions that may prevent diabetic complications in the presence of hyperglycemia, control of which is often difficult with current therapeutic options.

Acute renal failure is associated with high mortality and morbidity. Diuretic agents continue to be used in this setting despite a lack of evidence supporting their benefit. ⋯ The use of diuretics in critically ill patients with acute renal failure was associated with an increased risk of death and nonrecovery of renal function. Although observational data prohibit causal inference, it is unlikely that diuretics afford any material benefit in this clinical setting. In the absence of compelling contradictory data from a randomized, blinded clinical trial, the widespread use of diuretics in critically ill patients with acute renal failure should be discouraged.
