Prioritizing nutrition during recovery from critical illness

Abstract

Purpose of review: Patients admitted to the intensive care unit (ICU) often experience a significant decline in nutritional status due to a combination of the physiologic response to critical illness and insufficient calorie intake. The majority of research related to nutrition interventions for this population focuses on nutrition support during the acute phase. Minimal attention is given to the nutritional status of ICU patients during the recovery phase. This review will describe calorie intake when ICU care ends, provide an overview of barriers that limit intake, and possible interventions to improve nutritional status.

Recent findings: Current evidence suggests patients are consuming < 60% of calorie requirements after extubation and ICU discharge. This inadequate calorie intake may exacerbate weight loss and muscle and fat wasting. Physiologic, physical, and cognitive manifestations of critical illness can lead to multiple issues that cause poor intake. Possible interventions to improve calorie intake include a patient-centered approach that utilizes oral nutrition supplements and enteral nutrition.

Summary: Consuming adequate caloric intake in the recovery phase of critical illness is essential for rehabilitation. A systematic, patient centered approach that includes close monitoring of calorie and protein and timely interventions may be the best method to improve overall intake.
