Osaki et al reported risk factors for malnutrition following gastrectomy for gastric cancer. These can help to identify a patient who may benefit from nutritional interventions. The authors are from Japanese Red Cross Tottori Hospital in Japan.
Patient selection: status post gastrectomy for gastric cancer
Outcome: readmission within 1 year for nutritional difficulties
Rate of outcome: 4%
Predictors:
(1) type of gastrectomy (total gastrectomy, proximal partial gastrectomy, distal partial gastrectomy)
(2) modified frailty index of Velanovich et al
