Malnutrition appears to be a prevalent and largely unrecognized problem in hospitalized patients. The objectives of this study were; to screen for nutritional status of patients who underwent major abdominal surgery and to determine a relationship of nutritional status to health outcomes. Simple tools including subjective global assessment (SGA), body mass index (BMI), level of serum albumin (Alb) and total lymphocyte count (TLC) were used in the screening process. Prevalence of mal-nourished patients, length of hospital stay, and hospital cost were determined. Nutritional status of 300 patients underwent major abdominal surgery at Phramongkutklao Hospital were screened on admission and every seven days during hospitalization until discharge. Results showed that 34 patients (11.4%) were mal-nourished when SGA was used, but there was 16 (5.4%), 44 (14.6%) and 72 patients (24%) mal-nourished, when BMI, Alb, and TLC were screening tool, respectively, with the positive predictive value to SGA at 20%, 18.2%, and 40%, respectively. Well nourished patients spent less time and cost (6.1 days, 52,023.70 Baht) in hospital than patients with malnutrition (17.5 days, 95,979.30 Baht), or severe malnourished (16.6 days, 85,461.10 Baht). It is concluded that screening with SGA is possible and nutritional status of patients is associated with length of hospital stay and hospital.
