The Effect of Providing Drug Education on the Level of Treatment Knowledge in Type II Diabetes Mellitus Patients at the Kemayoran Community Health Center

Abstract

Background: Type II diabetes mellitus (DM) is a chronic health problem that requires long-term management, including adherence to medication. A patient's lack of knowledge about drug therapy can impact treatment success and increase the risk of complications. Drug education is a crucial nursing intervention in improving patient knowledge. Objectives: To assess changes in treatment-related knowledge before and after drug education among patients with type 2 diabetes mellitus at Kemayoran Community Health Center. Methods: A quantitative pre-experimental one-group pretest-posttest study was conducted at Kemayoran Community Health Center 31 patients with type 2 diabetes mellitus were selected using purposive sampling. Knowledge was assessed using the 23-item Indonesian Diabetes Knowledge Questionnaire (DKQ). Participants received standardized drug education through a lecture and leaflet. Pretest and posttest scores were analyzed using frequencies, percentages, and the Wilcoxon signed-rank test, with p < 0.05 considered statistically significant. Results: Good knowledge increased from 64.5% at pretest to 100.0% at posttest. The mean knowledge score increased from 17.13 ± 3.21 to 20.81 ± 1.84, and the median increased from 18 to 21. The Wilcoxon signed-rank test indicated a significant difference in knowledge scores before and after drug education (Z = -4.67; p < 0.001). Conclusion: Drug education was associated with improved medication-related knowledge among patients with type 2 diabetes mellitus at Puskesmas Kemayoran, Jakarta. Further controlled studies with larger samples and longer follow-up are needed to confirm the effectiveness and sustainability of the observed improvement.
