Risk factors for gastrointestinal bleeding in critically ill patients. Canadian Critical Care Trials Group.

Abstract: Background The efficacy of prophylaxis against stress ulcers in preventing gastrointestinal bleeding in critically ill patients has led to its widespread use. The side effects and cost of prophylaxis, however, necessitate targeting preventive therapy to those patients most likely to benefit. Methods We conducted a prospective multicenter cohort study in which we evaluated potential risk factors for stress ulceration in patients admitted to intensive care units and documented the occurrence of clinically important gastrointestinal bleeding (defined as overt bleeding in association with hemodynamic compromise or the need for blood transfusion). Results Of 2252 patients, 33 (1.5 percent; 95 percent confidence interval, 1.0 to 2.1 percent) had clinically important bleeding. Two strong independent risk factors for bleeding were identified: respiratory failure (odds ratio, 15.6) and coagulopathy (odds ratio, 4.3). Of 847 patients who had one or both of these risk factors, 31 (3.7 percent; 95 percent confidence ...

Participation in the occupations of everyday life.

Abstract: Participation or involvement in everyday occupations is vital for all humans. As described by the World Health Organization, participation has a positive influence on health and well-being. The presence of disability has been found to lead to participation that is less diverse, is located more in the home, involves fewer social relationships, and includes less active recreation. Occupational therapy is in a unique position to contribute to the development and fulfillment of participation for persons with and without disabilities. This article describes the nature and outcomes of participation. Characteristics to define and measure meaningful participation are outlined. Information about time use will help to develop an understanding of patterns of participation across locations, gender, culture, and the life span. Factors that affect participation within the environment, family, and persons are summarized. Occupational therapy research is needed to examine the complex relationship among person, environment, and participation in occupations. In practice and education, knowledge about participation can enhance the client-centered and evidence-based nature of occupational therapy services.
