Background: In 2001, an independent Nutritional support team (NST) for hospitalized children was first established in South Korea. Since then, pediatric NST teams have been implemented in many hospitals and have done a lot of work to support children’s nutritional improvement. The aim of this study was to investigate the current state of NST activity for hospitalized children through nationwide multicenter survey in South Korea. Methods: Out of 344 general and tertiary hospitals, 53 institutes having pediatric gastroenterologist and more than 10 pediatric inpatients were recruited. The questionnaire on NST activity was developed by the Nutrition Committee of Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition. The questionnaires were sent to pediatric gastroenterologists in each hospital. Survey was performed by e-mail, and some incomplete answers were asked on telephone. Results: Forty hospitals (75.5%) responded to the survey. Twenty-two (55%) hospitals managed NST jointly without distinction of children from adults. Fourteen (35%) hospitals had pediatric NST independent of adult NST. Four hospitals (10%) answered that hospitalized children didn’t receive any kind of nutrition support from NST. All required members including pediatrician, dietitian, nurse, and pharmacist were assigned for NST in 27 (67.5%) hospitals. While pediatric patients was 12.4% of total hospitalized patients, NST consultations for pediatric patients were 22.9% of total. Total 90.5% of adult NST consultation fee were covered by the national health insurance, whereas only 76.0% of pediatric NST consultation fee were covered, mainly by reason of repeated consultations within a week (70.7%). Only 10 (25%) of 40 hospitals answered that their NSTs were properly managing pediatric inpatients from nutritional aspect, while the others reported that nutritional management was not appropriate and main barriers were the lack of manpower and excessive work load (42.5%). Conclusions: Although this survey was performed targeting at general and tertiary hospitals with pediatric gastroenterologists, manpower and medical resources for effective nutritional support were still insufficient. In addition, national health insurance coverage of NST consultation still needs to be modified to improve current barriers to the implementation and management of pediatric NST.
