Introduction: heart failure is a chronic disease with the highest readmission duration. Increased health costs due to heart failure also continues to increase every year. The inability to take care of selfcare and non-adherence to treatment programs are the causes of high readmissions. This study aims to identify the effectiveness of electronic-based self-care on engagement, adherence, readmission, and quality of life and also aims to identify types of self-care intervention and electronic methods or applications used in self-care. Method: the research method is a systematic review of RCT (randomize control trial) research through systematic searches in 6 English-language databases, which were published from 2019 to 2023. Of the 134 journals identified self-care, engagement, adherence, quality of life and readmission, there are 114 articles were eliminated because they did not match the title, and of the 20 articles whose abstract results were identified as appropriate, there were 8 research references that met the inclusion and exclusion criteria, where the articles contained self-care electronic methods that were relevant to the variables in this systematic review. Data sources were taken from six data bases, namely PMC, Pubmed, Scopus, Proquest, ScienceDirect and ResearhGate. Results: the results show that the self-care intervention model electronic based has increased patient engagement (p<0,05), increasing adherence (p < 0,03), improved the quality of life of patients (p<0,05) and reduced readmissions (p<0,03) in heart failure patients. Conclusions: the conclusion is that electronic-based self-care can improve patient engagement, adherence with treatment programs, quality of life and reduce readmissions in heart failure patients. © 2025; Los autores.
