According to European Kidney Health Alliance (EKHA) currently, 1 in 10 Europeans has chronic kidney disease (CKD) and it is predicted to be the fifth leading cause of death worldwide by 2040. The COVID-19, pandemic has further worsened the situation, with CKD being the number one risk factor for CKD mortality, ahead of lung and heart disease. In addition to rising mortality figures, treatments for kidney disease have not improved substantially over the past 50 years, leaving too many kidney patients with a poor quality of life and reduced life expectancy. This situation is associated with staggering aggregate annual costs amounting to €140 billion per year in Europe, more than the annual healthcare costs of cancer or diabetes.&lt;/p&gt;&lt;p&gt;Many studies confirm that Information and Communication Technology intervention (ICT) in nephrology can be way to tackles this issue. The increased daily use of information and communication technologies (ICT) may lead to the need for healthcare professionals to monitoring patient remotely. Remote Patient Monitoring (RPM) have the potential to improve care for patients with kidney disease.&lt;/p&gt;&lt;p&gt;RPM may provide a means to overcome some of the aforementioned barriers. RPM is a framework for monitoring patients at home by digital, wireless technology and extends the interactive contact of conventional clinical settings to include the patient's home. The hope is that these technologies would improve clinical outcomes through earlier recognition and correction of problems. Although few studies on telehealth in the dialysis population exist, studies do support its technical feasibility, which patient acceptance of this technology is very high, and that RPM may be able to improve outcomes in other co-morbid states shared by the ESKD population.&lt;/p&gt;&lt;p&gt;According to Pan American Health Organization, CKD, also called kidney failure, describes the gradual loss of kidney function and is a worldwide public health problem, with adverse outcomes of kidney failure, CVD, and premature death.&lt;/p&gt;&lt;p&gt;This study collects the papers concerning RPM and renal patient management using ICT intervention to analyze the results from considering the bioengineer's point of view. Our focus was on technology contribution.&lt;/p&gt;&lt;p&gt;The aim of this study was to review and synthesize the available literature on the role of RPM in healthcare in nephrology. This systematic review was conducted to examine the content and results of publications on using RPM to improve the health care of patients with kidney disease, available to health care professionals (HCPs) and/or patients. The literature and our results confirm that in this field, RPM can allow cost reduction, improve the efficiency of healthcare resources, reduce human error, and overall improve the quality of life of kidney patients.&lt;/p&gt;&lt;/di","PeriodicalId":18997,"journal":{"name":"Nefrologia","volume":"44 5","pages":"Pages 639-667"},"PeriodicalIF":2.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0211699524000055/pdfft?md5=57adc466e049e9af72954e126ab6cd3a&pid=1-s2.0-S0211699524000055-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139814503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
