An online game that delivers diabetes self-management education (DSME) resulted in continuous HbA1c improvements, according to a randomized trial involving 456 individuals.
Participants with HbA1c ≥58 mmol/mol and taking oral diabetes medications were randomly assigned to either a DSME team-based game and an accompanying civics booklet or a civics game with a DSME booklet for 6 months. The games sent 2 questions twice weekly, awarded points based on performance, and provided modest financial rewards. Investigators looked at HbA1c change over 1 year. Among the results:
- Patients who played the DSME game saw their HbA1c reduced by −8 mmol/mol, compared with −5 mmol/mol for those in the other group.
- HbA1c reductions were greater in patients with baseline levels >75 mmol/mol: −16 mmol/mol in DSME game players, and −9 mmol/mol in civics game players.
The authors noted that the DSME game approach may work particularly well for geographically dispersed patients.
