The purpose of this research was to examine the nutritional status of chronically critically ill (CCI) patients receiving supplemental nutrition. Measures included calories recommended, measured versus estimated energy demands, and calories ordered versus calories received. Subjects: Data were collected on 44 chronically critically ill patients who had at least one indirect calorimetry (IC) measurement. All were receiving enteral or parenteral feedings at the time of IC measurement. Conceptual Framework: Subjects were enrolled in a larger study investigating factors associated with adult failure to thrive syndrome in long-term (>72 hours) ventilator patients. Method: All data were obtained from the medical record. Admission data were used to calculate estimated energy expenditure (Harris-Benedict equation). Each IC measurement was 30 minutes in duration. Five minute interval readings were averaged for a mean calculation of energy demand/expenditure. Results: Patients’ mean age=60 years (range 25-93); mean length of stay=34 days (range 11-107); mean length of mechanical ventilation=21 days (range 6-49); 36% did not survive the index hospitalization. On average, the patient’s first IC measurement was done on the 15th day after admission (range 4-40). Correlation statistics will be used to illustrate the relationships of IC to estimated energy expenditure, calories recommended (per dietician), calories ordered (per physician) and calories received (per nursing). Barriers to measuring energy demands and energy intake are presented. Conclusion: CCI patients who survive the life threatening phase of critical illness continue to require extensive support services. When undernourished, these patients are at an increased risk for complications and increased length of hospitalization. Identification of patients who do not receive adequate nutrition can enable clinicians to adjust orders to meet patients’ needs. However, further study is needed to understand the numerous complexities of what constitutes ‘adequate’ nutrition and the optimal method for determining energy demands.
