Assessing nutritional status in chronically critically ill adult patients.

BACKGROUND: Numerous methods are used to measure and assess nutritional status of chronically critically ill patients. OBJECTIVES: To discuss the multiple methods used to assess nutritional status in chronically critically ill patients, describe the nutritional status of chronically critically ill patients, and assess the relationship between nutritional indicators and outcomes of mechanical ventilation. METHODS: A descriptive, longitudinal design was used to collect weekly data on 360 adult patients who required more than 72 hours of mechanical ventilation and had a hospital stay of 7 days or more. Data on body mass index and biochemical markers of nutritional status were collected. Patients' nutritional intake compared with physicians' orders, dieticians' recommendations, and indirect calorimetry and physicians' orders compared with dieticians' recommendations were used to assess nutritional status. Relationships between nutritional indicators and variables of mechanical ventilation were determined. RESULTS: Inconsistencies among nurses' implementation, physicians' orders, and dieticians' recommendations resulted in wide variations in patients' calculated nutritional adequacy. Patients received a mean of 83% of the energy intake ordered by their physicians (SD 33%, range 0%-200%). Patients who required partial or total ventilator support upon discharge had a lower body mass index at admission than did patients with spontaneous respirations (Mann-Whitney U = 8441, P = .001). CONCLUSIONS: In this sample, the variability in weaning progression and outcomes most likely reflects illness severity and complexity rather than nutritional status or nutritional therapies. Further studies are needed to determine the best methods to define nutritional adequacy and to evaluate nutritional status.

Knowledge, attitudes, and predictors of advance directive discussions of registered nurses.

The purpose of this study was to describe nurses' knowledge, attitudes, and experiences regarding advance directives. A secondary purpose was to examine predictors of advance directive discussions between nurses and patients. Seven-hundred and nineteen respondents, randomly selected from a list of registered nurses in the state of Ohio, completed mailed questionnaires. Descriptive t test, chi-square, and logistic regression statistics were used in the data analyses. The respondents were knowledgeable and possessed positive attitudes about advance directives. Higher self-perceived confidence in advance directive discussion skills and the experience of caring for at least one patient with a current advance directive were found to be significant predictors of advance directive discussions. These findings suggest that experience with advance directives documents is critical for nurses' comfort and that developing interventions to further nurses' confidence in their discussion skills may increase advance directive discussions.

Research partners: two teams, one study population.

BACKGROUND: Two large research projects funded by the National Institutes of Health, the Disease Management project and the Thrive study, which examine different phenomena in the chronically critically ill population, have combined research teams. Each study has its own project manager and maintains a separate database and budget. Operational tasks for both grants are streamlined through the collaboration and cross-training of all team members. METHODS: The Disease Management project is a randomized clinical trial testing the effectiveness of a care program in improving outcomes for chronically critically ill patients and their caregivers during the first 2 months after discharge. The Thrive study is a prospective longitudinal investigation that aims to describe the weaning patterns of chronically critically ill patients as well as the patterns of illness-related variables. RESULTS: To date, many participants (n = 400) have been enrolled in each study. The results of both studies will be available through future publications. CONCLUSIONS: Although much information has been gleaned from gathering longitudinal data across one study population and examining two rich data sets, there are some limitations to this collaboration.

Use of advance directives in the chronically critically ill.

Although it would be ideal that all patients have the presence of an advance directive documented in their medical chart, it is especially important in the chronically critically ill, a patient population with an in-hospital mortality rate of 40%. How has the documentation of advance directives in the medical chart of chronically critically ill patients changed from 1997 to 2003? This article describes the patient characteristics and patterns of death in chronically critically ill patients, with or without an advance directive, enrolled in 2 consecutive studies.
