Introduction:The short-term admission facilities can be used for up to 30days in a row per month,and short-stay users with a maximum of 30days were more likely than expected,and they learned that re-hospitalization would be a reset or a waiting place for the next facility. In addition,in the case of 40 bedsor less,there is no placement standard of a dietitian and a registered dietitian,in a environment where nutritional management by the profession can not be managed, the elderly are prone to low nutrition due to a decrease in physical function,etc.,during the use of up to30 days,This study was conducted to clarify the importance of nutrition status and nutritional management of users, thinking that the possibility of users, thinking that the possibility of falling into low nutrition increased.Method: The target is 25 cases of elderly people who agreed to this study using the short stay of the nursing care complex between November 1, 2017 and April 30, 2018, and 17 cases of women.Survey items: age, height, weight, weight loss, upper arm perimeter (AC), triceps subcutaneous fat thickness (TSF), lower leg circumference (CC: calf) was measured, The amount of basal metabolism and the required amount of nutrition was used by Harris Benedict\u27s formula. Measuring instruments: Using Abbott\u27s Addipometer (Caliper), Insert tape, MNA®CC measure. Usage scale: ADL:Barthel Index. Evaluation of nutritional status: Mini Nutritional Assessment-Short Form was used for evaluation. In order to assess the risk of low nutrition among the elderly in the incoming, we investigated daily life independence, cognitive independence, meal intake during admission, presence of appetite loss, presence or absence of eating and swallowing disorders, presence of pressure ulcers, dementia, and the degree of need for care.Results:The total number of data collected was 25, eight men and 17 females. All have been judged to be elderly people with dementia. Mean age 84.9 years old(68-94 years old), average weight 47.1 kg, average BMIwas 20.7. The average amount of nutrients required was about 1300 to 1400kcal, but the least small was 1012kcal, and the most common was 1857kcal, and it was found that there was variation. The daily amount of food provided by the facility was about 1600kcal, and it was found that some people were short of nutritional supplementation even if they ingested the entire amount. Although the intake of the meal during the admission was maintained as imagined, the correlation with BMI and the amount of basic metabolism was low, and it was suggested that it was necessary to consider whether the meal provided by the related facilities was appropriate. It is suggested that it is difficult for the elderly to show up to the weight even if the whole amount of the meal is taken, and it is suggested that it is appropriate to use the weight (BMI22 is good, how much is good if BMI is good), and how many kcal is put on the weight? It is also necessary to consider which factor is appropriate.Conclusion:In the elderly, muscle mass decreased with age, and as a result, the basal metabolism showed a significant downward trend, and it was found that the individual difference increased. In order to avoid low nutrition, we need to better understand the characteristics of the elderly, and work with nurses, physical therapists, occupational therapists, etc., to provide detailed nutritional care and management to suit the characteristics of the individual. the importance of carrying out the in addition, it was suggested that the elderly who used short stays needed to implement nutritional management that took into consideration the amount of basic metabolism and the amount of nutrition required
