International hospital accreditation and clinical nutrition service in acute care hospitals in South Korea: results of a nationwide cross-sectional survey.

BACKGROUND AND OBJECTIVES: Beginning in 2007, 29 hospitals in South Korea have received accreditation from Joint Commission International (JCI). The present study aimed to identify differences in clinical nutrition service provisions between JCI accredited acute care hospitals and non-accredited acute care hospitals. A survey questionnaire was sent to all 43 acute care hospitals in South Korea. METHODS: A total of 35 sets of clinical nutrition service surveys, 234 sets of clinical dietitian job satisfaction surveys, and five-day daily work logs from 129 clinical dietitians were received. We used Fisher's exact test and independent t-test to analyze differences between acute care hospitals based on JCI accreditation. STUDY DESIGN: Nationwide cross-sectional survey. RESULTS: JCI accredited acute care hospitals (N=8) showed a higher, but not significantly higher, nutritional intervention rate of 12.7% among malnourished patients, compared with 7.0% in non-JCI accredited acute care hospitals (N=27). Analysis of work hours of clinical dietitians indicated time spent on direct care was higher (p<0.05), while time spent on outpatient care was lower (p<0.05) among JCI accredited acute care hospitals relative to non-JCI accredited acute care hospitals. CONCLUSIONS: Accreditation from JCI has a positive influence in the advancement of not only the hospital services, but also clinical nutrition services.

Intensive nutritional counseling improves PG-SGA scores and nutritional symptoms during and after radiotherapy in Korean cancer patients.

PURPOSE: This study was conducted for the nutritional assessment of cancer patients undergoing radiotherapy (RT) and to investigate the changes in nutrition status, oral intake, morbidity and quality of life (QOL) in cancer patients after intensive nutrition counseling. METHODS: Eighty-seven cancer patients were randomized to either a nutrition counseling group (n = 44, age 58.0 ± 2.2 years) or a control group (n = 43, 62.0 ± 1.8 years). Nutrition counseling accompanied RT, and the subjects received at least three sessions of individualized dietary counseling over the duration of RT. Assessment parameters were nutritional intake (24-h recall method), nutritional status Patient-Generated Subjective Global Assessment (PG-SGA), QOL and blood parameters including albumin. All parameters were measured at baseline, at the end of RT, and 1 month after the termination of RT. RESULTS: Body weight, body mass index (BMI), and energy and protein intake for the intervention and control groups did not differ significantly between baseline and the end of RT. However, at 1 month follow-up, protein intake was significantly decreased in the control group (p < 0.05). Blood albumin, total protein (TP), total lymphocyte count (TLC) were not different between the two groups. According to PG-SGA stage, at 1 month follow-up, patients in the intervention group showed increased number of patients with stage A status (well nourished). In addition, insomnia and nausea was significantly improved in the intervention group assessed by QOL. CONCLUSION: We suggest that repetitive and intensive nutritional counseling is necessary to improve QOL and to prevent deterioration of nutritional status in cancer patients receiving RT.

The Association of Metabolic Syndrome and Serum γ-Glutamyl Transpeptidase: A 4-Year Cohort Study of 3,698 Korean Male Workers.

The aim of the present study was to examine the causal-effect of baseline (year 2004) serum γ-glutamyl transpeptidase (GGT) level with the prevalence of metabolic syndrome (MS) in year 2008. The study was comprised of male workers who underwent a regular health check-up in 2004 and 2008. MS was diagnosed according to the American Association of Clinical Endocrinologists (AACE) criteria. In the subgroup analysis according to serum GGT level, triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) showed a significant increasing tendency (p < 0.001). In addition, unexpectedly results were consistent in non-drinkers (p < 0.001). GGT level was significantly associated with risk factors of MS (waist circumference [WC]: r = 0.18, p < 0.001; fasting blood glucose [FBG]: r = 0.16, p < 0.001; TG: r = 0.29, p < 0.001). As the secondary biomarker, homeostasis model assessment of insulin sensitivity (HOMA-S) and TC had significant correlations with GGT level (HOMA-S: r = -0.14, p < 0.001; TC: r = 0.21, p < 0.001). In the 4-year prospective analysis, the predictive effect of baseline GGT concentrations on change in MS status was evaluated using Cox proportional model. Elevated GGT concentrations measured in 2004 were associated with the risk of MS incidence after 4 years (GGT: HR 1.7 [95% CI: 1.2-2.3]) (p < 0.01). This observation indicates that an elevated GGT level could be suggested as a subsidiary marker for MS and partially reflects dyslipidemia as a component of MS.
