Anxiety has both functionally appropriate and inappropriate consequences. Among patients with cardiac disease, anxiety can be functionally appropriate when it prompts an individual to quickly seek treatment for acute cardiac signs and symptoms. But anxiety may have medical or psychological consequences when it is persistent or severe, including difficulty adhering to prescribed treatments and making recommended lifestyle changes, adoption of or failure to change risky behaviors, increased risk for acute cardiac events, and increased risk for in-hospital complications after admission for acute coronary syndrome. ⋯ The impact of psychosocial (with a major emphasis on anxiety) and behavioral variables on biological outcomes was examined systematically. The research included (1) examination and comparison of the intensity of anxiety in international samples of various critically, acutely, and chronically ill cardiac patients; (2) determination of differences between men and women in the expression of anxiety; (3) investigation of factors predictive of anxiety levels, including perceived control; (4) studies of healthcare providers' knowledge of anxiety assessment and providers' practices in assessing and managing anxiety; and (5) determination of the impact of anxiety on clinical outcomes in cardiac patients. The goal of this program of research is to improve patients' outcomes on a widespread basis by placing anxiety in the forefront of clinical cardiac practice.

Comparative Study
Comparison of point-of-care and laboratory glucose analysis in critically ill patients.
Blood for point-of-care analysis of glucose levels is often obtained from different sources (fingerstick, arterial or central venous catheter). ⋯ Glucose values for point-of-care samples did not differ significantly from laboratory values. For catheter samples, hematocrit and serum carbon dioxide levels accounted for the difference between point-of-care and laboratory glucose values.

Management of fecal incontinence is a priority in acute and critical care to reduce risk of perineal dermatitis and transmission of nosocomial infections. ⋯ The fecal management system can be used safely in hospitalized patients with diarrhea and fecal incontinence. Additional well-designed, controlled clinical trials may help to measure clinical and economic outcomes associated with the device.
