Abstract

As the widespread use of mobile health intervention among Korean patients with chronic disease, it is needed to identify research trends in mobile health intervention on chronic care using text mining technique. This secondary data analysis was conducted to investigate characteristics and main research topics in intervention studies from 2005 to 2018 with a total of 20 peer reviewed articles. Microsoft Excel and Text Analyzer were used for data analysis. Mobile health interventions were mainly applied to hypertension, diabetes, stroke, and coronary artery disease. The most common type of intervention was to develop mobile application. Lately, 'feasibility', 'mobile health', and 'outcome measure' were frequently presented. Future larger studies are needed to identify the relationships among key terms and the effectiveness of mobile health intervention using social network analysis.

국내 만성질환 관리에서 모바일 헬스 적용이 임상적으로 유용하다는 보고가 증가됨에 따라, 본 연구는 텍스트 마이닝 기법을 적용하여 국내 외 학술지에 게재된 국내 만성질환자 대상 모바일 헬스 중재연구의 특성 및 중심 키워드의 변화를 파악하고자 시도된 이차분석연구이다. 분석대상 논문은 2005년부터 2018년까지 학술지에 게재된 최종 20편으로, 추출한 텍스트는 Microsoft Excel을 활용하여 논문별 분석을 실시하였고, Text Analyzer를 사용하여 주제어를 추출하였다. 연구결과, 모바일 헬스 중재 연구는 고혈압, 당뇨병, 뇌졸중 관상동맥질환자에 주로 적용되었다. 가장 많이 사용된 중재 유형은 애플리케이션 개발이었으며, 최근 연구에서는 주로 '유용성', '모바일 헬스', '결과측정' 등의 단어들이 가장 많이 출현하였다. 추후 만성질환자 대상 모바일 헬스 중재에 관한 국내 외 연구 모두를 포함하여 주제어 간의 연관성을 확인할 수 있는 사회연결망 분석방법을 적용하여 그 효용성을 확인해볼 것을 제안한다.
