Objectives: Survey on medication compliance rate and related factors in people with type 2 diabetes readmitted for inpatient treatment at 108 Central Military Hospital. Participants and methods: A cross-sectional descriptive study was conducted on 168 patients with Type 2 diabetes readmission from January 2021 to December 2022. The study assessed medication adherence using the MARS–5 questionnaire (Medication Adherence Report Scale 5). Results: The rate of medication compliance in patients was 21.8%, non-compliance accounted for 78.2%. Patients who occasionally forget to take medication account for the highest rate of 51.8%, arbitrarily reducing the dose to less than the prescribed dose accounted for 32.1%, rarely skipping doses, and stopping medicine for a period of time accounted for 35.7% and 50.2%, respectively. There was a relationship between age and current medication and medication compliance. The difference was statistically significant(p <
0.05). Conclusion: The medication compliance rate in diabetic patients readmitted to the hospital in the study was low, only 21.8%, of which patients forgot to take medication and arbitrarily reduced the dose and stopped using medication for a period of time accounting for the highest proportion. high rate. Strengthening health education on medication adherence during follow-up examinations for patients and caregivers is extremely necessary to reduce the risk of hospital readmission, maintain blood sugar at normal levels, and minimize diabetes complications
