Effectiveness of Insulin-use Counseling Among Outpatients with Diabetes at Hung Ha General Hospital

Abstract

Objective: The study aimed to evaluate the effectiveness of insulin-use counseling among outpatients with diabetes at Hung Ha General Hospital. Subjects and methods: An interventional study was conducted among outpatients with diabetes at Hung Ha General Hospital from February 1st to September 30th, 2025. Results: A total of 148 patients fulfilled the inclusion criteria and completed the study. Medication adherence increased significantly from 76.4% to 85.8% following the counseling intervention (p < 0.001). The majority of drug-related problems (DRPs) associated with insulin-use behaviors identified at baseline were resolved after the intervention, with a 61.3% reduction in the total number of DRP. The proportion of patients experiencing hypoglycemia decreased from 54% to 41.9% (p < 0.05). Additionally, injection-site adverse drug reactions (ADRs), including bleeding, bruising, and pruritus, declined from 10.8% to 6.7%. Conclusion: Insulin-use counseling significantly improved medication adherence, reduced insulin-related drug-related problems (DRPs), and lowered the incidence of hypoglycemia among outpatients with diabetes mellitus. These findings highlight the essential role of pharmaceutical counseling in optimizing outpatient diabetes management.
