This study was conducted to investigate the factors that influence the psychosocial adaptation and quality of life of hemodialysis patients. The study participants consisted of 246 hemodialysis patients from 8 hemodialysis centers located in 3 cities ('K', 'P', and 'U') in South Korea. The questionnaire used for data collection was administered between April 1 and 30 of 2014. SPSS/WIN 18 program was used to perform descriptive, correlation, and stepwise regression analyses. It was found that stress response and acceptance were significantly correlated with psychosocial adaptation and quality of life. In the stepwise regression analysis, stress response appeared to be the most important influencing factor for psychosocial adaptation (${\beta}$=-.443, p<.001) and quality of life (${\beta}$=-.553, p<.001). Based on the study results, it is determined that in order to improve psychosocial adaptation and quality of life among hemodialysis patients, an intervention program to reduce stress response is needed, along with evaluating its efficacy.

This study was designed to investigate the effect of aromatherapy on skin xerosis and pruritus in patients undergoing maintenance hemodialysis. Twenty one subjects of this study were selected from St. Paul's Hosipital in Seoul. All the subjects were received the mineral oil massage at the arm without fistular three timesper week for 4 weeks. After 2 weeks period of wash-out, the subjects were received the aromatherapy of lavender and tea tree essence oil in the same way. This study was carried out from March 20 to June 13, 1998. Pruritus score, skin pH and stratum corneum hydration were measured before and after each treatment. But, biochemical parameters were measured before the treatment of the mineral oil massage, after the treatment of the mineral oil massage and the aromatherapy. Data of this study were analyzed by paired t-test, repeated measures ANOVA, Bonferroni multiple comparisons and Pearson correlation coefficient. The results were as follows ; 1. Pruritus score was significantly decreased after the aromatherapy, while no significant change after the treatment of the mineral oil massage. Therefore, there was a significant difference in the priritus score between the two treatments. 2. Stratum corneum hydration was significantly increased after the aromatherapy, while no significant change after the treatment of the mineral oil massage. Therefore, there was a significant difference in the stratum corneum hydration between the two treatments. 3. Skin pH was significantly increased after the treatment of the mineral oil massage, while no significant change after the aromatherapy. Therefore, there was no significant difference in the skin pH between the two treatments.4. After the aromatherapy, the serum calcium was significantly increased. Whereas the serum parathyroid hormone intact was significantly decreased compared with the treatment of the mineral oil massage. But the level of the serum Ca and PTH-intact were within the normal range. 5. Stratum corneum hydration was decreased corresponding to the duration of hemodialysis, while pruritus score and skin pH showed no change corresponding to the duration of hemodialysis and the age of the subjects. The correlation of pruritus score on skin pH, stratum corneum hydration and biochemical parameters was not significant. In conclusion, this findings indicate that aromatherapy may be effective in decreasing skin xerosis and pruritus score in uremic pruritus patients undergoing maintenance hemodialysis.

Purpose: The purpose of this study was to provide evidence for future research by analyzing the contents, delivery methods, and educational effects of educational programs for hemodialysis patients. Methods: A literature review was conducted in the following order: problem identification, literature search and data collection, data evaluation, data analysis, and data presentation. In total, 936 documents were retrieved from the search, and 24 documents were finally included in this study. Results: The contents of the educational programs were comprehensive hemodialysis-related knowledge education in seven studies, exercise-related education in 10 studies, diet-related education in four studies, drug-related education in one study, and complex education in two studies. The delivery methods were pamphlets in six studies, audio-visual materials in four studies, direct guidance by researchers in six studies, and multiple methods in seven studies. The effects of the educational program were divided into physical indicators, emotional indicators, and knowledge and performance related to hemodialysis. Sixteen out of 20 articles using physical indicators showed significant outcomes, and 10 out of 12 articles using emotional indicators derived positive results. Hemodialysis-related knowledge and performance were measured in eight and 10 studies, respectively, and meaningful results were found in six studies for knowledge and seven studies for performance. Conclusion: Future research will require the development of a systematic and standardized educational program with comprehensive content that can be provided to all hemodialysis patients, as well as a highly accessible education delivery method to enhance the effectiveness of education.

Objectives: The valid assessment of food and nutrients intakes using appropriate dietary intake method is necessary to improve the nutritional status of the hemodialysis (HD) patients. This study was conducted to compare the method between newly developed, semi-quantitative food frequency questionnaire (Semi-FFQ) and 7-day dietary records (7-DRs) for hemodialysis patients. Methods: We conducted both methods on 53 maintenance HD patients in two university hospitals. We calibrated the frequency, portion size and daily intake of 47 food items reported in Semi-FFQ. The food and nutrients intake was compared and the correlation of the two methods was analyzed. Also each nutrient intake was compared to recommended dietary allowance for Korean (KDRIs) and recommended nutrient reference value for HD patients. Results: Energy and energy-yielding nutrients intakes were significantly higher in the two methods (p<0.01). These support the possible reliability between Semi-FFQ and 7-DRs that is similar with regard to most mineral and vitamin intakes. Thus, the Semi-FFQ used in this study for the assessment of nutrient intakes of HD patients can be reliable for the assessment of the nutrient intake along with the 7-DRs. The correlation coefficients were higher for foods consumed daily, such as steamed rice, meat and chicken, bean, egg, milk, coffee and alcohol than for those of foods eaten rarely (p<0.01). Conclusions: The Semi-FFQ used in this study can be a reliable tool for the assessment of the HD patients' nutrient intake along with the 7-DRs, despite its limitations.

Background: Today, survival rate of patients with chronic renal failure/hemodialysis has increased so that chronic illnesses are more likely to occur. Cancer is the main cause of morbidity and mortality in such patients. Aim: In this study, physician attitudes were examined about cancer screening in patients with renal failure. Materials and Methods: This study was done by face to face questionnaire in the $27^{th}$ National Nephrology Congress to determine if the physicians dealing with chronic renal failure, hemodialysis or renal transplanted patients, recommend cancer screening or not and the methods of screening for cervix, prostate, breast and colon cancer. Results: One hundred and fifty six physicians were included in the survey. A total of 105 (67%) participants were male and the age of responders was $48{\pm}9$ years. About 29% were specialists in nephrology, 28% internal medicine, and 5% were other areas of expertise. Some 48% of participants were hemodialysis certified general practitioners. Patients were grouped as compensated chronic renal failure, hemodialysis or renal transplanted. Of the 156 responders, 128 (82%) physicians recommended breast cancer screening and the most recommended subgroup was hemodialysis patients (15%). The most preferred methods of screening were combinations of mammography, self breast examination and physicianbreast examination. 112 (72%) physicians recommended cervix cancer screening, and the most preferred method of screening was pap-smear. Colon cancer screening was recommended by 102 (65%) physicians and prostate screening by 109 (70%) physicians. The most preferred methods of screening were fecal occult blood test and PSA plus rectal digital test, respectively. Conclusions: It is not obvious whether cancer screening in renal failure patients is different from the rest of society. There is a variety of screening methods. An answer can be found to these questions as a result of studies by a common follow-up protocol and cooperation of nephrologists and oncologists.

Purpose: The objective of this study was to determine the cause-effect and dynamic change mechanism among factors that affect calculation of the nursing workforce in the hemodialysis room and to establish a system dynamics model and create a strategic simulation to be used to increase efficiency in the clinical situation. Method: The system dynamics approach was adapted to build a simulation model for calculating the nursing workforce. The model was built using Vensim 5.0b DSS. Results: The results were as follows for Scenario A: The highest level of nursing service quality, patient satisfaction, and nurse satisfaction, and the lowest level of turnover intention is maintained when the ratio of patients to nurse is 3.5:1 compared to all other situations. Scenario B: At the ratio of patients to nurse 4.0:1 nursing service quality, patient satisfaction, and nurse satisfaction dropped slightly, and turnover intention also rose slightly. However with time the results showed improvement. Conclusion: In terms of economic efficiency in the hemodialysis room, the ratio of patients to nurse for the best nursing workforce should not exceed 4.0:1.

Purpose: This study was done to provide fundamental data for nursing interventions to prevent and reduce fatigue and to identify fatigue and kidney disease symptoms in female patients on hemodialysis and evaluate factors associated with this fatigue. Method: A cross-sectional study design was used with self-administered questionnaires which included general characteristics and the fatigue scale developed by Brown, Dittner, Findly, & Wessely(2005)(Cronbach's $\alpha=0.98$ and for present study $\alpha=0.96$) and a review of laboratory data. From eight dialysis units, 84 women were enrolled. Data were analyzed using the SAS program. Results: Mean score for fatigue was 49.4(range $16{\sim}78$) and fatigue by research variables was significantly different by age(0.046), employment status(0.041), menopause(0.009), hypoalbuminemia(0.022), length of time on dialysis(0.48) and kidney disease symptoms(0.000). Correlations between fatigue and lack of strength, dizziness, and cramps after dialysis were significantly higher. Factors affecting fatigue were kidney disease symptoms and length of time on dialysis, explaining 49.2% of fatigue. Conclusion: A comprehensive approach considering kidney disease symptoms, length of time on hemodialysis, age, menopause, and hypoalbuminemia are required for interventions to reduce fatigue in female patients on hemodialysis.

The object of this study is to develop a mathematical model of the hemodialysis system including the mechanism of solute kinetics, water exchange and also cardiovascular dynamics. The cardiovascular system model used in this study simulates the short-term transient and steady-state hemodynamic responses such as hypotension and disequilibrium syndrome (which are main complications to hemodialysis patients) during hemodialysis. It consists of a 12 lumped-parameter representation of the cardiovascular circulation connected to set-point models of the arterial baroreflexes, a kinetic model (hemodialysis system model) with 3 compartmental body fluids and 2 compartmental solutes. We formulate mathematically this model in terms of an electric analog model. All resistors and most capacitors are assumed to be linear. The control mechanisms are mediated by the information detected from arterial pressoreceptors, and they work on systemic arterial resistance, heart rate, and systemic venous unstressed volume. The hemodialysis model includes the dynamics of urea, creatinine, sodium and potassium in the intracellular and extracellular pools as well as fluid balance equations for the intracellular, interstitial, and plasma volumes. Model parameters are largely based on literature values. We have presented the results on the simulations performed by changing some model parameters with respect to their basal values. In each case, the percentage changes of each compartmental pressure, heart rate (HR), total systemic resistance (TSR), ventricular compliance, zero pressure filling volume and solute concentration profiles are represented during hemodialysis.
