Effect of Nutritional Risk at Admission on the Length of Hospital Stay and Mortality in Gastrointestinal Cancer Patients

This retrospective study was conducted to determine whether increased length of hospital stay (LOS) and mortality are associated with nutritional risk upon hospital admission in gastrointestinal cancer patients, using a computerized screening tool developed by a university hospital. We included adult gastrointestinal cancer patients whose hospital stays ranged from 24 hours to 90 days. The sample included 4,345 patients. The average age of the patients was 60.5 +/- 11.4 years and 2,959 (68.1%) were males. The mean of LOS was 8.2 +/- 8.2 days and the mortality rate was 3.4% (n = 146). The majority of the patients were at low risk (LG) (n = 3,102 [71.4%]), while 779 patients (17.9%) were at moderate risk (MG), and 464 (10.7%) were at high risk (HG). In comparing the three groups based on nutritional risk, hospital LOS was significantly longer in the HG (11.4 +/- 11.4 days) than it was in the LG (7.7 +/- 7.9 days) and the MG (7.9 +/- 7.9 days) (p < 0.0001). Significant differences were found in the hospital mortality rate, which was the highest in the HG (13.6%) and the lowest in the LG (1.5%) (p < 0.0001). In the multiple logistic regression analysis, moderate-to-severe nutritional risk, increased age, and emergency admission were selected as significant variables for increased LOS and mortality. Further research is needed to evaluate the benefits of nutritional screening and intervention and their effect on outcomes in various disease populations.

Avoidable Causes of Delayed Enteral Nutrition in Critically Ill Children

To evaluate the incidence of delayed enteral nutrition (EN) and identify avoidable causes of delay, we retrospectively reviewed medical records of 200 children (median age [range]; 37.5 [1-216] months) who stayed in the intensive care unit (ICU) for a minimum of 3 days. Among 200 children, 115 received EN following ICU admission with a median time of EN initiation of 5 days after admission. Of these, only 22 patients achieved the estimated energy requirement. A significant decrease in the final z score of weight for age from the initial assessment was observed in the non-EN group only (-1.3+/-2.17 to -1.57+/-2.35, P<0.001). More survivors than non-survivors received EN during their ICU stay (61.2% vs 30.0%, P=0.001) and received EN within 72 hr of ICU admission (19.8% vs 3.3%, P=0.033). The most common reason for delayed EN was gastrointestinal (GI) bleeding, followed by altered GI motility and hemodynamic instability. Only eight cases of GI bleeding and one case of altered GI motility were diagnosed as active GI bleeding and ileus, respectively. This study showed that the strategies to reduce avoidable withholding EN are necessary to improve the nutrition status of critically ill children.
