Continuous Glucose Monitoring (CGM) supports Type 2 Diabetes (T2D) management, but healthcare professionals (HCPs) often face challenges interpreting data. E-learning platforms can enhance knowledge, skills and confidence. This systematic review identified enablers and barriers to e-learning for CGM interpretation.

Systematic review conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

PubMed, Ovid MEDLINE, Ovid Embase, Cochrane Library, Scopus, Web of Science and CINAHL were searched on 7 February 2024.

Studies of HCPs using e-learning for T2D management were included, both comparative and non-comparative. Outcomes included enablers and barriers. Eligible designs were randomised, quasi-experimental, controlled before-and-after and observational studies. No restrictions on setting or language; conference abstracts included if full text was available

Two reviewers independently screened and extracted data using a predefined form; disagreements were resolved by a third reviewer. Thematic analysis identified key enablers and barriers. Methodological quality was assessed using the Downs and Black checklist, and findings were synthesised narratively.

Four studies met inclusion criteria, including 6790 participants (physicians, nurses, midwives and medical residents). E-learning improved knowledge and skills. Emami et al reported increased knowledge of T2D diagnosis and treatment (p=0.001), while Okuroğlu and Alpar found improvements in diabetes care knowledge and skills (pet al noted enhanced self-reported performance (p=0.03) and 84% satisfaction. Enablers included flexibility and accessibility, while barriers involved time constraints, resistance to change and methodological limitations (self-selection bias, lack of blinding). Study quality ranged from fair (three studies) to poor (one study).

Based on current evidence, it is unclear if e-learning can significantly enhance HCPs’ knowledge, skills and confidence in T2D management. Barriers such as time constraints and resistance to change remain, and the limited number and quality of studies restrict the generalisability of these findings. E-learning may offer potential benefits, but further robust randomised controlled trials are needed to evaluate long-term outcomes and strategies to overcome these challenges.
