The rapidly growing aged population is challenging conventional methods of care provision. Global ageing, combined with other challenges, has compelled health systems to explore new methods for providing health care. Telenursing, providing nursing care at a distance using new technologies, is identified as one alternative. The lack of evidence for the effectiveness of telenursing in aged care is a drawback for its wider use. The aim of this chapter is to review the evidence of randomised controlled trials (RCT) in geriatric telenursing practices. We performed a systematic literature review using the Ovid Medline and Pubmed databases on telenursing. A total of 62 articles were retrieved and 18 studies were selected for comprehensive analysis. The review found that the RCTs were conducted in different areas of geriatric telenursing and various information and communication technologies (ICT) were used in the interventions. Although robust evidence, based on RCTs in aged care telenursing is yet to emerge, the majority of current studies suggest that telenursing is an effective tool.
