We assessed whether cancer patients given a nutritional consultation by dietitians when discharged from the hospital experienced more health benefits than those not given a nutritional consultation. The McNemar test and the general linear model were used to examine the effect of nutrition intervention. A bubble chart was plotted to show the comparison between cancer groups. A total of 537 cancer patients discharged from a 1200-bed medical centre in Taiwan in 2011 were randomly divided into experimental and control groups. In the experimental group, nutritional status [evaluated using the Subjective Global Assessment (SGA) Classification technique], weight loss, and food intake recovery were significantly affected and returned to their usual levels, but in the control group, only food intake recovery was significantly affected. The effect of nutrition consultation intervention for cancer patients is thus evident. Significant positive effects were cancer-stage-dependent but not cancer-type-dependent. Future studies are recommended using the present study's methods to see whether the nutrition intervention effect occurs in cancer patients discharged from other hospitals throughout the world.
