The COVID-19 pandemic affects blood glucose control in patients with type 2 diabetes mellitus (type 2 DM). Internet-based interventions show great potential in type 2 DM patients care. The aim of the study is to identify internet-based self-care monitoring interventions in type 2 DM patients during the COVID-19 pandemic. Using a systematic scoping review of PubMed, CINAHL, SAGE Journals, and ScienceDirect spanning 2019-2022, full-text articles, and randomized controlled trials. Study quality was assessed using the Joanna Briggs Institute (JBI) appraisal tool. Overall, 12 studies revealed that the internet was effectively used for self-care monitoring in type 2 DM patients during the COVID-19 pandemic such as to monitor blood sugar, diet, physical activity, drug use, problem solving, and dealing with stress, including mobile health (applications), web, telephone, and SMS (Short Message Service). Our finding highlights internet-based self-care monitoring can be a model of nursing intervention to prevent and increase the quality of life in DM patients.
