Low calories intake reduces mortality, length of hospital stay among ICU patients

The inclusion criteria were met by twenty-two studies comprising 9 539 participants and were subjected to the network meta-analysis. Secondary outcomes include clinical outcomes, nosocomial infection, digestive infections, functions, improved quality of life, ventilator days, resulting survival rates, bacteremia, diarrhoea, blood glucose levels, and tube replacement.

The study revealed the following findings:

• In mortality rates, the greatest rank observed corresponded to a reduction of 71%.
• The regression of the effects of low caloric intake explained a 5.29% variation in LOS.
• A weak positive correlation was found between LOS and low caloric intake among critically ill patients in ICUs.
• Low caloric intake decreased mortality rates and lowered LOS.

"Our findings have clinical implications for clinicians in the ICU, who should consider the development of individualised nutritional plans for critically ill patients," the researchers wrote. "Moreover, it is crucial to regularly monitor nutritional intake and response."

"Healthcare providers should closely monitor patients' vital signs, nutritional status, and clinical outcomes," the researchers concluded.
