ObjectiveTo evaluate and synthesize evidence on the impact of educational interventions for individuals with insulin-treated type 2 diabetes mellitus (T2DM).MethodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, five electronic databases (Scopus, PubMed, Medline, CINAHL Plus with Full Text, and Web of Science) were systematically searched in February 2024. The search focused on studies published between 2019 and 2024 that investigated the impact of educational interventions on individuals with insulin-treated T2DM. Reference lists of the included studies were also manually searched. Titles and abstracts were screened for eligibility, and relevant full texts were assessed.ResultsOut of 1,032 identified records, 11 studies met the inclusion criteria. According to the data synthesized using a convergent integrated analysis framework, five major themes have emerged: 1) Glycemic control (including subthemes improving HbA1C, decreasing postprandial plasma glucose, and decreasing fasting plasma glucose), 2) Insulin-related complications (including subthemes reducing hypoglycemic events and reducing the size of lipohypertrophy), 3) Knowledge, Attitude, and Practice (including subthemes engaging in self-management, improving insulin injection technique, improving knowledge, and improving attitude toward insulin treatment), 4) Optimal dose of insulin, and 5) Improving quality of life.ConclusionEducational interventions are crucial for improving diabetes-related outcomes and reducing complications in individuals with insulin-treated T2DM. These interventions enhance knowledge, attitudes, and self-management practices, leading to better glycemic control and quality of life. Healthcare settings should develop and provide tailored educational programs for individuals with insulin-treated T2DM to optimize outcomes and minimize complications.© 2024 Riangkam et al.
