PURPOSE: This study compared the elderly falls and the intrinsic fall risk factors according to gender. METHODS: This descriptive cross-sectional study was a secondary analysis of the data collected for medical checkups for the Transitional Periods of Life supported from the National Health Insurance. The subjects examined were 255,505 people aged 66 years in Korea between January and December, 2008. RESULTS: The elderly people aged 66 when in the transitional periods of life experienced 10.6% of their first falls. The first falls of women (12.4%) was greater than that of men (8.5%) in the elderly. The risk factors for falls included dysuria with an odds ratio of 6.2 to 6.6, depression with an odds ratio of 1.5 to 1.8, gait disturbance with an odds ratio of 1.3 to 1.5, and blindness with an odds ratio of 1.3 to 1.4 in both elderly women and men. CONCLUSIONS: Effective fall prevention should focus on dysuria because it is a more important predictor of falls, even though many intrinsic fall risk factors can affect falls in elderly people.

Due to aging society, the prevalence of dementia is continually increasing and, thereby, causing a serious issue. Although Long Term Care Insurance is provided on a national level, it is not available for the elderly with dementia who do not satisfy the requirements. As the use of smartphones becomes widespread, this study investigated an application that can help disease management of the elderly with the early-stage (mild) dementia and communication among the family members based on analysis of the functions found in currently-available applications and survey among the relevant subjects. As a research method, based on review of the relevant theoretical studies, the service environment of applications available for the elderly with mild dementia was analyzed. Through this analysis, it found out that there is no application for the eldery with mild dementia. On the basis of the results, this study proposed a direction for design planning of an application included many functions like managements of taking medicine, physical activity, brain activity, information on dementia and notes. for dementia management aimed to help the patients with mild dementia manage the disease on their own. If this type of services are expanded in addition to the systemic support from the government, the data collected from these applications can contribute to improving management of mild dementia.

Neonatal intensive care in Korea has improved remarkably since the 1990s, but there is still a shortage of facilities and equipment in NICUs. Only 71.1% of the beds needed for neonatal intensive care are available. Mechanical ventilators are not appropriately distributed to the NICUs that are equipped to handle neonatal intensive care. The number of doctors is far too small, making the number of patients per doctor very high. Nurses, too, need to take care of 7.7 patients per nurse, making it very difficult to provide adequate intensive care. All this is caused by insufficient investment by the hospitals, which, in turn, is caused by inadequate reimbursement from health insurance. Therefore, a government-sponsored effort is necessary to bring the level of neonatal intensive care up to par.

This study tried to find the relationship between household income level and medical expense to household income ratio. For data analysis, it used 2010 and 2011 yearly data beta version of Korea Health Panel, co-managed by Korea Institute for Health and Social Affairs and National Health Insurance Corporation. To find out how the effect of independent variable changes in 2010 and 2011, the interaction effect between year and independent variable was examined, and separating the factors that showed interaction effect into each year, linear regression analysis was conducted using generalized estimating equations method. As a result of reviewing the factors that were related to medical expense to household income ratio among the people who used medical services, it was found that the higher the household income level, the lower the medical expense. It indicates that policy measures are needed to lessen the medical burden of low-income families.

The purpose of this study was to investigate consciousness about the disabled on dental hygiene students and search for course of dental hygiene education as oral health care with the disabled. The subjects in this study were 538 dental hygiene students from three college in Jeonnam province. For statistical analyses of collected data, the descriptive analyses and chi-square were adopted. The obtained results were as follows. Seniors showed positive attitude about the disabled and dental service of the disabled(p<0.05). The common types of contact the disabled were physical Cerebral palsy and inner disabled were rarely. The problems are difficulty in communication, short of clinical experience in dental service of the disabled, noncooperation of the disabled, short of knowledge in dental service of the disabled. To dental service of the disabled, demand as necessity of education was 87.5%, theory and practice at the same time was 68.0% in pattern of education. Finally, 49.5% of respondents observed special dental clinic to utilization pattern of dental service of the disabled.

In order to analyze the variation in length of stay(LOS) of injury inpatients, we developed severity-adjusted LOS model using Korean National Discharge In-depth Injury Survey data of Center for Disease Control. Appling this model, we calculated predicted values and, after standardizing LOS using the differences from the actual values, analyzed the variation in LOS. Major factors affecting severity-adjusted LOS of injury inpatients were found to be severity, surgery(or no surgery), age, injury mechanism and channel of hospitalization. Result of analysis of the differences between the actual values and predicted values adjusted by decision tree model suggested that there were statistically significant differences by hospital size(number of beds), type of insurance and location of institution. In order to reduce the variation in LOS, efforts should be exerted in developing nationwide treatment protocol, inducing medical institutions to utilize it, and furthermore systematically evaluating it to reduce the variation continually.

In this study, we analyzed the effect of the income level of cancer, stroke, and myocardial infarction on mortality by using National Health Insurance Service(NHIS) Cohort 2.0 DB. Patients who newly developed the disease in 2007 were observed till 2015. The analysis used the Cox probability proportional risk model and the competing risk model. The income level used information at the time of the onset of the disease in 2007, categorized into low / mid / high. The results showed that there were differences in the risks of death and secondary disease in patients with cancer, stroke, or myocardial infarction according to the income level. In addition to the need for a social safety net to lower the incidence of early deaths in low-income families, it seems necessary to continue to strengthen universal protection for serious diseases similar to the current policy.

This study considers time series models to forecast drug expenditures in national health insurance. We adopt autoregressive error model (ARE) and transfer function model (TFM) with segmented level and trends (before and after 2012) in order to reflect drug price reduction in 2012. The ARE has only a segmented deterministic term to increase the forecasting performance, while the TFM explains a causality mechanism of drug expenditure with closely related exogenous variables. The mechanism is developed by cross-correlations of drug expenditures and exogenous variables. In both models, the level change appears significant and the number of drug users and ratio of elderly patients variables are significant in the TFM. The ARE tends to produce relatively low forecasts that have been influenced by a drug price reduction; however, the TFM does relatively high forecasts that have appropriately reflected the effects of exogenous variables. The ARIMA model without the exogenous variables produce the highest forecasts.
