The authors enrolled 277 subjects with acute respiratory failure to describe the epidemiology of depressive disorders and antidepressant use during and after intensive care. By SCID criteria, the prevalence of major depressive episode at 2 months was 16%, and 16% had depressive disorder not otherwise specified. ⋯ At 2 months, the prevalence of antidepressant medication use was 49%, and the incidence was 28%. Depression and antidepressant pharmacotherapy are frequent during recovery from acute respiratory failure.

The authors studied factors associated with referral of delirium patients to psychiatry consultation and its outcome implications. Characteristics and treatment outcomes of delirium patients referred to psychiatry were compared with those not referred. Referred patients were younger, had a more hyperactive subtype, greater substance abuse, less comorbid dementia, were more likely to be recognized as having delirium, and be prescribed medications. ⋯ No differences were noted in length of stay, discharge status, or mortality within 1 year of the index episode. Psychiatric interventions were moderately helpful. Patients' characteristics and delirium subtypes may influence referral and should inform future liaison efforts.

Antipsychotic drugs are the primary treatment for symptoms of delirium, but their side effects can be problematic. Treatment of delirium with aripiprazole has yet to be evaluated. The authors report on 14 patients with delirium treated with aripiprazole. ⋯ There was a low rate of adverse side effects. Aripiprazole may be an appropriate first-line agent for the treatment of delirium because of its minimal effect on QTc interval, weight, lipids, and glucose levels. Controlled comparison studies should be performed to confirm this impression.

Dyspnea is a common symptom of heart failure frequently relied upon to assess clinical functioning. The purpose of this study is to explore a broad range of medical, psychological, and social factors that correlate with dyspnea in heart failure patients. Seventy-six participants ranged from well-compensated, ambulatory subjects to those with recent hospitalization for acutely decompensated heart failure. ⋯ Correlation analysis revealed that dyspnea significantly correlated with depression, fatigue, and overall health perception. Standard regression analyses indicated that depression, fatigue, and overall health perception uniquely contributed to dyspnea, explaining 38.0% of the total variance. The present study confirms that dyspnea is multifactorial, with links to psychological distress and overall health perception.
