Factors impact on insufficient nutrition and effects of timely adequate nutrition support on patient outcomes in adult intensive care patients

Results 133 male and 87 female patients were included. 151 patients reached the target caloric intake.Mean target calorie was 1579 kcal/d in the adequate caloric intake group, and 1739 kcal/d in insufficient caloric intake group (p < 0.001).The number of comorbidities in both groups were similar (1.91 ± 1.07/1.87 ± 1.00; p >0.05).According to logistic regression analysis parenteral nutrition and lymphoma were found to be major independent risk factors for insufficient calorie intake. The most common cause for cessation of nutrition was detection of a residual. Nosocomial infection frequency in adequate and insufficient caloric intake groups were similar, respectively. Enteral nutrition was the most effective feeding way in adequate caloric intake group (p < 0.002). Parenteral nutrition and immunosuppressive treatment were major independent risk factors for mortality based on logistic regression analysis.Mortality of patients in adequate and insufficient caloric intake groups was 53% and 76%, respectively (p < 0.002).
