Purpose: In countries with a large elderly population, the integrated visiting health care program for the elderly in communities was effective in preventing frailty and reducing medical expenses. Customized preventive health service is essential in a super-aged society. The purpose of this study is to estimate the number of professionals who perform visiting health care for the elderly. Methods: The statistics for the elderly from Statistics Korea and the Visiting Healthcare Performance Report from Korea Health Promotion Institute were employed in the analysis. The elderly were divided into four groups: healthy, pre-frailty, frailty I, and frailty II, according to their health level. Through the focus group interview, the ratio of nurses, physical activity experts, and nutritionists was set at 8:1:1. Results: Three scenarios were classified into minimum, medium, and maximum according to the number of visits. In the case of Seoul, the number of essential professionals was calculated at least from 719 to a maximum of 1,837. Conclusion: Since this study has a limitation in calculating visiting health care experts only by the ratio of nurses, physical activity experts, and nutritionists, future studies should consider experts or professionals in the field of social welfare, oral health, and visiting treatment.

Purpose: Given the rapid aging of the population in Korea, many studies have emphasized the community efforts to slow down or prevent frailty of older adults who are living alone. However factors that affect frailty among older adults living alone remain unclear. This study aimed to identify the factors affecting frailty among community-dwelling older adults living alone. Methods: This secondary data analysis used data of 126 older adults who are living alone. Levels of frailty, depression, social activity and social support were self-reported and physical function (Timed up and go test results and handgrip strength) were measured. Data were analyzed with descriptive statistics and multiple linear regressions. Results: The overall mean score for frailty was 5.13 out of 20. Age, timed up and go test results, and social support were found to be statistically significantly associated with the frailty of older adults living alone. Conclusions: Identification of significant physical and social factors affecting frailty among older adults living alone is beneficial for developing community-based healthcare. The development of community-based multi-component intervention or facilitating home-visit nursing care should be considered to slow down frailty and promote good health.
