Glycated hemoglobin (HbA1c) levels decreased from 7.13% (SD = 1.74%) at baseline to 5.93% (SD = 1.00%) post-intervention, with a mean reduction of 1.20% (95% CI, 0.98-1.42%, <i>t</i> = 10.54, <i>p</i> < 0.001), indicating a statistically and clinically significant improvement.<h4>Conclusion</h4>Addressing insulin injection problems identified in the county community through establishing a targeted special QM program is beneficial for improving diabetes control and management at the community level.
