  • Purpose: This study was conducted to explore the impact of registered nurse/nurses' aid (RN/NA) staffing and turnover rate on inpatient health outcomes in long term care hospitals. Methods: A secondary analysis was done of national data from the Health Insurance Review and Assessment Services including evaluation of long term care hospitals in October-December 2010 and hospital general characteristics in July-September 2010. Final analysis of data from 610 hospitals included RN/NA staffing, turnover rate of nursing staff and 5 patient health outcome indicators. Results: Finding showed that, when variables of organization and community level were controlled, patients per RN was a significant indicator of decline in ADL for patients with dementia, and new pressure ulcer development in the high risk group and worsening of pressure ulcers. Patients per NA was a significant indicator for new pressure ulcer development in the low risk group. Turnover rate was not significant for any variable. Conclusion: To maintain and improve patient health outcomes of ADL and pressure ulcers, policies should be developed to increase the staffing level of RN. Studies are also needed to examine causal relation of NA staffing level, RN staffing level and patient health outcomes with consideration of the details of nursing practice.

  • Objectives: The objective of this study was to estimate the risk of lung cancer in relation to angiotensin II receptor blocker (ARB) use among patients with hypertension from the Korean National Health Insurance Service-National Health Screening Cohort. Methods: We conducted a retrospective cohort study of patients with hypertension who started to take antihypertensive medications and had a treatment period of at least 6 months. We calculated the weighted hazard ratios (HRs) and their 95% confidence intervals (CIs) of lung cancer associated with ARB use compared with calcium channel blocker (CCB) use using inverse probability treatment weighting. Results: Among a total of 60 469 subjects with a median follow-up time of 7.8 years, 476 cases of lung cancer were identified. ARB use had a protective effect on lung cancer compared with CCB use (HR, 0.75; 95% CI, 0.59 to 0.96). Consistent findings were found in analyses considering patients who changed or discontinued their medication (HR, 0.50; 95% CI, 0.32 to 0.77), as well as for women (HR, 0.56; 95% CI, 0.34 to 0.93), patients without chronic obstructive pulmonary disease (HR, 0.75; 95% CI, 0.56 to 1.00), never-smokers (HR, 0.64; 95% CI, 0.42 to 0.99), and non-drinkers (HR, 0.69; 95% CI, 0.49 to 0.97). In analyses with different comparison antihypertensive medications, the overall protective effects of ARBs on lung cancer risk remained consistent. Conclusions: The results of the present study suggest that ARBs could decrease the risk of lung cancer. More evidence is needed to establish the causal effect of ARBs on the incidence of lung cancer.

  • The purpose of this study was to identify risk factors predictive of alterations in skin integrity during the intraoperative period. The predictive risk factors were studied for intraoperative pressure sores from December 1998 through January 1999. A sample of 220 patients was selected from the operating room schedule of a University Hospital in Pusan. There were two criteria in including patients : the operation lasted longer than 2 hours and the absence of skin break-down according to NPUAP criteria. The data were analized by SPSS/PC, Stepwise multiple logistic regression was used to identify the variables which were predictive of alterations in skin integrity. Of the 220 patients studied, 41 patients (18.6%) developed stage 1 pressure sores in the immediate postoperative period. In relation to skin changes, three independent variables emerged from the stepwise multiple logistic regression as being significant (p<0.05). Factors predictive of pressure sore formation included low serum albumin(p=0.000), prone position while undergoing surgery(p=0.0004), time on the operating table(p=0.0165). Among the intrinsic factors, serum albumin was the most significant causal factor in pressure sores development in the intra-operative period. Pressure and shearing force were the most significant extrinsic factors in pressure sores development. From the results of this study we concluded that the primary nursing goal is the maintenance of the proper patient' position during the intraoperative period. Also imperative for sore prevention is the reduction of surgery time and improving preoperative nutritional status.

  • Systemic health conditions increase with advancing age, and may be linked to poor self-reported oral health. The purpose of this study was to evaluate the association between systemic health conditions and poor self-reported oral health among Korean elderly. The study used a nationally representative sample of Koreans (2012 Korea National Health and Nutrition Examination Survey) aged 65~98 years (n=1,595). Systemic health conditions in this population were assessed by the presence of one or more of the following conditions: obesity, hypertension, diabetes, and hypercholesterolemia. The relative risk of poor self-reported oral health according to the occurrence of systemic health conditions was estimated by multivariate logistic regression after controlling for several potential confounders (i.e., socio-demographic factors, oral health behaviors, health behaviors, and psychological factors). After adjustment for these confounders, the relative risk of having poor self-reported oral health was greater among the elderly with one or more systemic health conditions than in those without a systemic health condition. The odds ratio of having poor self-reported oral health according to the occurrence of systemic health conditions was 1.51 (95% confidence interval, 1.08~2.12). Among the Korean elderly, perception of poor oral health was associated with the presence of one or more systemic health conditions. Future studies are needed to examine the detailed causal relation between systemic health conditions and poor oral health longitudinally.

  • This study was done to provide an understanding of nursing in relation to the existential philosophy of the West and Buddhistic philosophy, It examined how human beings and death are interpreted and understood in existential philosophy as well as in Buddhistic philosophy. Then the study suggested that nursing should focus on helping the sufferer to find meaning and a sense of responsibility in his or her existence. When people have the opportunity to realize certain important but painful truths about their existence, they develop internal strength and control of their lives. Just as people learn to face their being, so can they come to terms with their non-being. According to the causal process in Buddhism, Human Being is not always annihilation of self. Therefore, birth, aging, disease and death go through the process of natural change and it is the appearance of human existence which is inherent in the health of every human being. To promote our health we must gain an insight about this phenomenon. This study viewed nurses' clients as 〈good friend〉 rather than 〈patient〉 which focuses on a disease-oriented concept. The concept of 〈good friend〉 views nurses' clients as active participants to create their life and as responsible persons in a constantly changing life. The study also examined the concept of recovery which means to come back to the previous healthy state and it suggested that the concept of recovery should be changed to 〈good change〉, because in existential philosophy, human beings are viewed as never going back to the past but moving on to the future by creating their existence. This study also suggested that nursing should help 〈good friend〉enlighten their existence to be free from pain and death and to get control over their existence.

  • This study was conducted to identify the characteristics of social carrying capacity at mega-events, especially the 2000 Kwangju Biennale in Korea. In particular, this paper has proposed some management policies for mega events taking into account the relations between social carrying capacity, satisfaction and crowding. The research method was to look into the general characteristics and distributive forms of the location, and then to confirm the possibility of sampling the factors involved in satisfaction degree; last, A factor analysis for causal analysis of perceived crowding was performed. The study needed correlation analysis in order to compare expected crowding and perceived crowding, and performed regression to examine the causality of perceived crowding and satisfaction. The research results were as follows: the correlation of expected crowding, perceived crowding, and the total satisfaction was very low or meaningless. The relation between satisfaction and elements for factor analysis such as convenient facilities and value experience showed partial meaningfulness. The factors of convenient facilities, entrance fee, parking lot use, toilet convenience, and exhibit room use had meaningful results; on the other hand, the factors of value experience showed a meaningful result in the guide service of an event place. In conclusion when those holding an event make a basic project, they should consider management measures for convenience of facilities, proper education for guide service, and systematic guidance. Also, as a method for perceived crowding lower than expected crowding, the study has proposed that it is possible to lower expected crowding by providing appropriate information on the number of tourists expected on the weekends and weekdays. Future research should control variables such as personal characteristics, seasons proper for vacation and holidays, and carefully consider their investigation and design. Moreover, it is necessary to study variables involved in expected crowding of more various space-intensive sightseeing places (mesa-events).
