  • This study explored the impact on the DRG(Diagnosis-Related Groups)-based prospective payment system(PPS) operated by voluntarily participation providers. We analyzed whether the provides in the DRG-based PPS and in traditional fee-for-service(FFS) systems showed different the degree of variation in length of stay(LOS), and the providers' behaviors depending on the differences according to the varied participation periods. The study sample included all data 2,061 institutions participated in DRG-PPS in 2007 and all cases 473 FFS institutions which reported fee-for-service claims were reviewed same diagnosized diseases at least 10cases claims during three months We compared the differences of the LOS among health care institutions according to their type, region, and size. For DRGs showing significant differences in LOS, multiple regression analyses were performed to find out factors associated with LOS and interaction effect participation and hospital types or participation periods. The result provide the evidence that the DRG payment system operated by volunteering health care institutions had impact on resources use, which can reduce the institutions' the length of stay. While some DRGs had no correlation between participation periods and LOS, other DRGs, DRG participation period reversely linear relationship with LOS. That is to say, the longer participation year, the less reducing the LOS. These results support the future expansion of the DRG-based PPS plan to all health care services in Korea.

  • Purpose: The purpose of this study was to investigate the influence of communication competence and burnout on nursing performance in intensive care units (ICU). Method: The participants were 209 nurses from four university hospitals. Measurements included a socio-demographic and job related survey, communication competence inventory, the Maslach burnout inventory and a nursing performance scale. Data were collected from February 6 to 24, 2012, with a self-report questionnaire. The statistical analyses were performed with SPSS 18.0 software. Results: The mean scores for communication competence, burnout and nursing performance were 50.49, 84.72, and 62.18, respectively. Communication competence (r=.44, p<.001) and burn out (r=-.32, p<.001) were significantly correlated with nursing performance. In the multiple linear regression, factors influencing nursing performance were communication competence, age and burnout. These variables explained about 46% of the total variance of nursing performance. Communication competence (${\beta}$=.34, p<.001) was the most influential factor. Conclusion: Nurses' poor communication skills and burnout can influence the occurrences of medical errors in ICU nursing performance. The results suggest that good communication and burnout resolution skills programs should be implemented to improve nursing performance efficiency.

  • Purpose: The study was done to examine hemodialysis unit nurses' knowledge on blood-borne infections, compliance and barriers to control and predictors of compliance. Methods: A descriptive correlational study was conducted with 122 nurses from hemodialysis units. Data were collected using a structured questionnaire. The data collection period was May to September, 2017. Data were analysed using descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple linear regression. Results: The mean score for knowledge on blood-borne infections was $15.41{\pm}2.01$ out of 19 and the compliance with blood-borne infection control was $4.08{\pm}0.49$ out of 5. Barriers to the performance of blood-borne infections control were lack of time and personal protective devices. Knowledge on blood-borne infection did not correlate with compliance on blood-borne infection control (r=.13, p=.171). Predictors of compliance on blood-borne infections control were 1) infection control education on injuries caused by injection needles (${\beta}=.23$, p=.010), 2) infection control room (${\beta}=.24$, p=.006) and 3) blood exposure experience over the past week (${\beta}=-.24$, p=.005) and explained 22.2% of the variance (F=10.81, p<.001). Conclusion: Findings suggest that to improve the performance of blood-borne infectious disease management, customized education for nurses on blood-borne infection and systematic support related to the infection control room should be given priority.

  • Objectives : Recurrence of mood episodes associated with a specific season has been described in various mood disorders. Seasonal change in mood and behavior as a lifetime trait is also observed in healthy individuals. This study aimed at comparing the lifetime trait of seasonal variations of mood and behavior between bipolar disorder patients and controls as well as investigating associated factors of seasonality. Methods : Subjects were ninety-four clinically stable patients with bipolar disorder and 188 age- and sex-matched healthy controls. Seasonality of mood and behavior was assessed retrospectively on lifetime basis using Seasonal Pattern Assessment Questionnaire(SPAQ). Results : The patient group showed a higher median global seasonality score(GSS) of SPAQ and a higher rate of seasonal affective disorder(SAD) compared to the control group(p < 0.0001). For subjects showing prominent seasonality, the seasonal symptom profile and seasonal pattern was similar in both patient and control groups. In addition to the diagnosis, female gender was shown to be a predictor of seasonality in the multiple linear regression analysis(p = 0.045). Conclusion : This study suggests that lifetime trait of seasonality may be related to the susceptibility of bipolar disorder.

  • Purpose: This study examined knowledge about cardio-cerebrovascular disease (CVD) and its relationship to health behaviors among middle-aged postmenopausal women with CVD risk factors. Methods: The study was a cross-sectional descriptive study. One hundred and thirty-six postmenopausal women were recruited from outpatient departments of four hospitals. The women were $60.69{\pm}6.5$ years old. Self-reported questionnaires were administered, and waist-hip ratios (WHR) were measured. Results: Among the women, 72.8% reported hypertension, 19.1% reported diabetes, 33.8% reported hypercholesterolemia, and 24.2% reported angina pectoris. Moreover, 73.9% of the women reported not knowing of CVD prevention, and only 26.1% reported exercising regularly. A majority of the women (80.9%) had a WHR > 0.85. Multiple linear regression analysis after adjusting for age and marital status indicated that the risk of myocardial infarction and stroke increased (p<.001). Waist-hip ratio${\leq}0.85$ (p=.022) and living with family members (p=.006) were significant predictors of healthier behaviors ($R^2$=0.21, p<.001). Knowledge of CVD and health behaviors were not correlated. Conclusion: Obese women and women who live alone are no more likely to practice health behaviors aimed at CVD prevention than their counterparts in the sample. Education and exercise interventions are needed, especially for obese women, to promote healthy behaviors among middle-aged postmenopausal women with CVD risk factors.

  • Background: Whether depression causes increased risk of the development of breast cancer has long been debated. We conducted an updated meta-analysis of cohort studies to assess the association between depression and risk of breast cancer. Materials and Methods: Relevant literature was searched from Medline, Embase, Web of Science (up to April 2014) as well as manual searches of reference lists of selected publications. Cohort studies on the association between depression and breast cancer were included. Data abstraction and quality assessment were conducted independently by two authors. Random-effect model was used to compute the pooled risk estimate. Visual inspection of a funnel plot, Begg rank correlation test and Egger linear regression test were used to evaluate the publication bias. Results: We identified eleven cohort studies (182,241 participants, 2,353 cases) with a follow-up duration ranging from 5 to 38 years. The pooled adjusted RR was 1.13(95% CI: 0.94 to 1.36; $I^2=67.2%$, p=0.001). The association between the risk of breast cancer and depression was consistent across subgroups. Visual inspection of funnel plot and Begg's and Egger's tests indicated no evidence of publication bias. Regarding limitations, a one-time assessment of depression with no measure of duration weakens the test of hypothesis. In addition, 8 different scales were used for the measurement of depression, potentially adding to the multiple conceptual problems concerned with the definition of depression. Conclusions: Available epidemiological evidence is insufficient to support a positive association between depression and breast cancer.
