Gros A, et al. - Researchers performed a retrospective analysis of data from critically ill patients with shock to determine the prognostic value of body-weight variations occurring each day from day 3 to day 7 on the 30-day outcome in terms of mortality, occurrence of ventilator-associated pneumonia and of bedsore, and occurrence of length of stay. Outcomes of this prospective multicenter cohort study suggested the possible utility of body-weight variations during the first days of stay in the intensive care unit (ICU) as a clinically relevant tool to prevent weight gain and for prognostication of 30-day mortality, occurrence of ventilator-associated pneumonia, and occurrence of prolonged ICU stay.
