Current clinical practice guidelines delineate optimal nutrition management in the intensive care unit (ICU) patient. In light of these existing data, the authors identify current physician perceptions of nutrition in critical illness, preferences relating to initiation of feeding, and management practices specific to nutrition after initiation of feeding in the ICU patient. ⋯ This study demonstrates a substantial discordance in physician perceptions and practice patterns regarding initiation and management of nutrition in ICU patients, indicating an urgent need for nutrition-related education at all levels of training.

A comparison between ventilation modes: how does activity level affect energy expenditure estimates?
An appropriate diet is essential to avoid complications of overfeeding or underfeeding in mechanically ventilated intensive care unit (ICU) patients. The paucity of consistent comparative data on energy expenditure for each ventilation mode complicates diet prescription. This study evaluates caloric requirements by comparing estimated and measured energy expenditure values for 2 ventilation modes. ⋯ Results suggest that a 10% activity factor should be adopted only for assisted ventilation because multiplication by an activity factor may lead to overfeeding of patients on controlled ventilation.
