Objective: This study aims to conduct systematic literature review on the studies related to frailty in Korea, and to suggest implications necessary for the direction of studies in the future.
Methods: A systematic literature review was performed on all literature published in Korea related to frailty. The criteria for selection of the target literature were those that had frailty as the main research topic and that presented methods such as cohort studies, case-control studies, and clinical trials. Studies not related to frailty, studies with unclear methodologies, genetic studies, studies on animals, and studies not targeting Koreans were excluded. After reviewing the 45 documents finally selected through the above criteria, the literatures were classified and categorized according to the similarity of the research topic.
Results: In this study, three categories of frailty studies were established: ‘risk factors of frailty’, ‘health outcomes due to frailty’, and ‘effects of the intervention program’. According to the selection criteria for this study, a total of 45 articles were included, 30 articles on factors related to frailty and health outcomes, and 15 articles on the effects of the intervention program.
Conclusions: In order to overcome frailty, it is essential to conduct a comprehensive study using multiple interventions and effects from multiple angles. In future studies on frailty in Korea, it is necessary to study various and comprehensive risk factors on frailty and the characteristics of the elderly. It is also necessary to develop and study various indicators of health outcomes due to frailty. Finally, it is necessary to study the effects of a comprehensive and complex intervention program using a cohort and to prove a causal relationship. Through this, it is ultimately necessary to prepare a strong evidence for the risk factors, health outcomes, and intervention programs of frailty, thereby laying the foundation for national policy implementation for overcoming frailty among the elderly in Korea.
