Several studies about hospital malnutrition have been reported that about more than 40% of hospitalized patients are having nutritional risk factors and hospital malnutrition presents a high prevalence. People in a more severe nutritional status ended up with a longer length of hospital stay and higher hospital cost. Nutrition screening tools identify individuals who are malnourished or at risk of becoming malnourished and who may benefit from nutritional support. For the early detection and treatment of malnourished hospital patients , few valid screening instruments fur Koreans exist. Therefore, the aim of this study was to develop a simple, reliable and valid malnutrition screening tool that could be used at hospital admission to identify adult patients at risk of malnutrition using medical electrical record data. Two hundred and one patients of the university affiliated medical center were assessed on nutritional status and classified as well nourished, moderately or severely malnourished by a Patient-Generated subjective global assessment (PG-SGA) being chosen as the 'gold standard' for defining malnutrition. The combination of nutrition screening questions with the highest sensitivity and specificity at prediction PG-SGA was termed the nutrition screening index (NSI). Odd ratio, and binary logistic regression were used to predict the best nutritional status predictors. Based on regression coefficient score, albumin less than 3.5 g/dl, body mass index (BMI) less than $18.5kg/m^2$, total lymphocyte count less than 900 and age over 65 were determined as the best set of NSI. By using best nutritional predictors receiver operating characteristic curve with the area under the curve, sensitivity and 1-specificity were analyzed to determine the best optimal cut-off point to decide normal or abnormal in nutritional status. Therefore simple and beneficial NSI was developed for identifying patients with severe malnutrition. Using NSI, nutritional information of the severe malnutrition patient should be shared with physicians and they should be cared for by clinical dietitians to improve their nutritional status.

본 연구에서는 다발성 외상 중환자에게 있어 급성 단계에서의 이화학적 상태 및 경장영양 공급 수준이 임상적 예후에 미치는 영향을 알아보고자 하였다. 먼저 조사 대상자 302명의 특성을 분석한 결과, 남성의 비율이 높으며 다른 중환자실에 비해 연령이 낮게 나타났으며 과체중의 체격을 가지고 있었다. 입원 후 7일간의 경장영양 공급 수준에 따라 일반적 결과와 합병증 발생률, 영양 관련 생화학적 지표를 비교한 결과, 초기 경장영양이 가장 적극적으로 공급되었던 High EN 그룹에서 사망률, CRP에서 유의적으로 감소하였다. 질소 평형을 기준으로 이화상태가 양호한 그룹에서는 경장영양 공급 기간이 길수록 HAIs 발생률이 높았으나, 이화상태가 불량한 그룹에서는 적극적인 경장영양 공급에도 여러 합병증 발생이 증가하지 않았다. 생화학적 검사 결과에서는 그룹 간 유의적인 차이가 없었으며, 경장영양 공급 수준에 따른 사망률 감소 추세는 두 그룹 모두에서 유지되었다. 결론적으로, 본 연구에서는 사망률 감소, 염증 수치의 감소 등에서 초기 경장영양 공급 일수가 증가할수록 긍정적인 효과를 확인하였다. 단, 후향적 관찰연구라는 제한점을 미루어 보아 향후 연속적으로 이화상태를 모니터링 및 평가하며 기본 특성의 차이가 없는 그룹 간에서 경장영양 공급 수준을 차별화한 전향적 코호트 연구가 필요하겠다.

Cholestatic liver disease is a frequent complication of prolonged parenteral nutrition, especially in premature infants. Numerous factors have been cited as contributing to TPN associated cholestasis. However the exact etiology remains obscure. Ursodeoxycholic acid (UDCA) has been reported to be beneficial far children and adults with various chronic cholestatic liver disease. The aim of this prospective, randomized, double-blind, placebo-controlled study was to determine the preventive effects of UDCA administration during TPN. Seventeen pediatric patients (8 boys and 9 girls) undergoing TPN were assigned randomly to two groups, UDCA and placebo group. UDCA group (n=9) received 15 mg/kg/day UDCA and placebo group (n=8) received 15 mg/kg/day placebo enterally during the TPN period. Liver function tests (total bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase) were per-formed before TPN and weekly or three times a week. The patients' weights, complete blood count, composition of TPN, and the infusion rate of TPN and lipid were monitored everyday. Calcium and phosphate were monitored twice a week. Between the UDCA and placebo groups, there were no differences in weight at the onset of TPN, birth weight, duration of TPN, respiratory distress syndrome associated with prematurity, age at the onset of TPN, gestational age, the number of days the patients received antibiotics, the number of patients received enteral nutritions and the composition of TPN. In contrast, there was a significant difference between the UDCA and placebo groups in alanine aminotransferase levels during TPN. It doesn't seem that UDCA administration during TPN correlates directly with improvement of liver function. But the preventive administration of UDCA may be effective in reducing liver enzyme, alanine aminotransferase and has no adverse effects.

The purpose of this study was to investigate the status of clinical nutrition services at various medical centers in Seoul, Korea. A questionnaire was distributed to the departments of nutrition at 44 hospitals in Seoul on July 2009. Nutritional screening carried out at a rate of 59.1% at the medical centers, and a significant difference was found according to the type of center, from 100% in tertiary hospitals to 18.8% in normal hospitals. On annual average, the numbers of inpatients, inpatients for malnutritional screening, inpatients with malnutrition, and inpatients for malnutrition management were 15,169.5, 10,870.9, 2,224.8, and 1,546.2, respectively. On average the group nutrition education was done 36.1 times/year for diabetes, 8.2 times/year for cancer, and 1.9 times/year for renal disease, and the numbers of participants 423.1, 95.1, and 31.5, respectively. On average the individual nutrition education of inpatients with diabetes was done 135.4 times/year for ordered-type, and 119.3 times/year for unordered-type, 106.2 times/year for paid-type, and 148.5 times/year for unpaid-type. The mean fee for education and counseling was the highest for peritoneal dialysis (73,090.9 won) but the lowest for heart disease (23,609.1 won). On average the individual nutrition education of outpatients with diabetes was done 234.6 times/year for ordered-type, and 2.5 times/year for unordered-type, 204.4 times/year for paid-type, and 32.7 times/year for unpaid-type. The mean fee for education and counseling was also the highest for peritoneal dialysis (63,500.0 won) but the lowest for heart disease (21,336.4 won). To implement more effective clinical nutrition service, a national medical insurance imbursement policy should be urgently instituted such that diseases left as unpaid are covered by health insurance, including all nutrition-related disease.

The adequate dietary intake is important to maintain the nutritional status of the patients after pancreatic cancer surgery. This prospective study was designed to investigate the dietary intake and the nutritional status of the patients who had pancreatic cancer surgery. Thirty-one patients (15 men, 16 women) were enrolled and measured body weight, body mass index (BMI), nutritional risk index (NRI), and Malnutrition Universal Screening Tool (MUST). Actual oral intake with nutritional impact symptoms recorded on the clinical research foam at every meal and medical information were collected from electronic medical charts. The rates of malnutrition at admission were 45.1% (14/31) and 28.9% (9/31) by NRI and MUST method, respectively, but those were increased to 87% (27/31) and 86.6% (26/31) after operation on discharge. The median values of daily intake of energy, carbohydrates, fat, and protein were 588.1 kcal, 96.0 g, 11.8 g, and 27.0 g, respectively. Most patients (n = 20, 64.5%) experienced two or more symptoms such as anorexia, abdominal bloating and early satiety. There were negative correlations between C-reactive protein (CRP) levels and the intake of total energy, protein, fat, and zinc. The rates of malnutrition were increased sharply after surgery and the dietary intake also influenced the inflammatory indicators. The results suggested that need of considering special therapeutic diets for the patients who received pancreatic surgery.

Background and objective: The Seoul National University Bundang Hospital (SNUBH) implemented ward-based clinical pharmacy system with designated pharmacists in 10 general wards. Designated pharmacists conduct inpatient medication review, medication intervention, and medication consultation, and provide drug information for health care providers. This study aimed to evaluate the clinical pharmacy services and to examine the perception and expectations of health care providers on the services provided by the designated pharmacists in general wards. Methods: A survey was constructed to include questions on the health care providers' recognition, satisfaction, and perceived needs of designated pharmacists. We determined the frequency and type of interventions of ward pharmacist and their acceptance rate through a retrospective observational study using electronic medical records. Results: A total of 59 health care providers responded the questionnaire and 79.7% of the respondents reported moderate to high levels of satisfaction. Satisfaction with the services was positively associated with clinical interventions and nutrition support team (81.4%). Of 59 respondents, 88.1% agreed that preventing drug-related problems by designated pharmacists' activities were effective. The most common interventions included inadequate dosage (27.4%), omission and additional prescription (14.6%) and inadequate drug form (9.6%). The acceptance rate of intervention was 91.5%, and 151 potentially serious risks and 523 significant risks were prevented by the intervention. Conclusion: Positive results were confirmed in the awareness, satisfaction, and perceived needs of the health care providers for designated pharmacists. Expansion of the ward-based clinical pharmacy system with designated pharmacists to other wards may be considered.

Purpose: In this study, we investigated the clinical profile, survival at discharge, and proportion of children with acute liver failure (ALF) meeting the criteria for, yet surviving without, liver transplantation (LT). Methods: Medical case records of children aged >28 days to ≤15 years over a period of 7 years, identified from pediatric admission and discharge registers, were screened. Children satisfying the criteria for ALF were included in this study. Results: A total of 71 records meeting the pediatric ALF (PALF) criteria were included. The survival rate at discharge was 61% (n=44). A considerable proportion of children satisfied the King's College Criteria (KCC) (56.3%) and the European Association for the Study of the Liver (EASL) criteria (7%) for LT at admission. Nonetheless, the survival rate in the absence of LT was 42.5% in children who satisfied the KCC and 20% in those who met the EASL criteria. Infection (29.5%) and paracetamol overdose (19.7%) were the major identifiable causes of PALF. Hepatitis A was the most common infection identified. No significant predictors of poor outcomes were identified in multivariable analysis. Conclusion: Our study highlights the changing survival rates and the clinical and etiological profiles of patients with PALF. In areas with poor access to LT services, survival in these children could be improved through early referral to centers with adequate intensive care facilities. Preventing ALF and referring patients to LT services are paramount to reducing mortality.

Nutritional researchers world-wide are using large-scale sample survey methods to study nutritional health epidemiology and services utilization in general, non-clinical populations. This article provides a review of important statistical methods and software that apply to descriptive and multivariate analysis of data collected in sample surveys, such as national health and nutrition examination survey. A comparative data analysis of the Korea National Health and Nutrition Examination Survey (KNHANES) was used to illustrate analytical procedures and design effects for survey estimates of population statistics, model parameters, and test statistics. This article focused on the following points, method of approach to analyze of the sample survey data, right software tools available to perform these analyses, and correct survey analysis methods important to interpretation of survey data. It addresses the question of approaches to analysis of complex sample survey data. The latest developments in software tools for analysis of complex sample survey data are covered, and empirical examples are presented that illustrate the impact of survey sample design effects on the parameter estimates, test statistics, and significance probabilities (p values) for univariate and multivariate analyses.
