Nutritional screening tool
Some previous studies (2,10,21-25) have shown the effectiveness
of different nutritional screening tools. In the current study, a
high prevalence of moderate to severe NRS was observed and
NRS was correlated with the length of hospital stay in children
older than three years. To our knowledge, minimal literature is
available on the predictive value of the NRS for the duration of
hospitalization. Some concerns may be raised
about the validity of the NRS in children younger
than three years because of the difficulty of assessing
pain in this group
