The Differences of Nutrition Status, Energy Delivery and Outcomes between Metropolis and Regional University-Based Thai Surgical Intensive Care Units

The objective of this study was to compare the differences of nutrition status, nutrition delivery, and the outcomes between the metropolis (MUH) and regional university based hospitals (RUH) in Thailand. The nutrition data were retrieved from the THAI-SICU database. A total of 1,686 patients (MUH 927 patients vs. RUH 759 patients) with completion of nutrition status and nutrition delivery data were included in this analysis. The enrolled patients from study centers located in Bangkok were defined as MUH, and the patients from Chiang Mai were defined as RUH. Patient characteristics, nutrition status using the subjective global assessment (SGA) and nutrition risk screening (NRS), nutrition delivery, and outcomes of treatment were recorded. The outcome associations were analyzed by a multivariable regression model. At admission, there were significant differences of age, gender, body mass index, disease severity, albumin level, and diagnosis. RUH had significantly poorer nutritional status than MUH (RUH vs. MUH: SGA class B and C, 57.7% vs. 37.1%, p
