This nationwide survey was conducted in order to evaluate the current status of nutritional supports on surgical patients in Korea. Guideline and Clinical Trial Committee of the Korean Society of Surgical Metabolism and Nutrition (KSSMN) sent questionnaires to 101 KSSMN members (hospital-based) regarding the current activity of the nutritional support team (NST) in each hospital. We also asked them about their needs regarding development of clinical guidelines for nutritional support for surgical patients. Response rates were 39.6% (40/101). The majority of hospitals (35/40, 87.5%) have NST and the surgeon is a leader of the NST in 30 hospitals (85.7%). Round visits of the multidisciplinary team were held in 23 hospitals (23/35, 65.7%), however, it was executed irregularly at intervals of one week over in 23 hospitals (23/25, 92.0%). Screening tools for newly admitted patients were used in 26 hospitals (26/35, 74.3%). Almost all hospitals (27/30, 90.0%) screened all newly admitted patients using an electronic searching program. However, proportion referring to NST was extremely low. The cause of the low consult rate was indicated as a manpower shortage due to low reference fee. Most surgeons agreed on the need for development of clinical guidelines. The Authors hope that after this survey, comprehension of current circumstance of nutritional support is enhanced among surgeons, and that this will result in more positive activities in usual medical treatment condition.
