Background. Patients with type 2 diabetes mellitus (T2DM) who have limited knowledge about hypoglycemia and insulin pen use are likely to have hypoglycemia and other complications. Objective. This study aimed to evaluate the effectiveness of health education on knowledge about hypoglycemia and insulin pen use among outpatients with T2DM at a primary care hospital in Vietnam. Methods. A pretest–posttest study was conducted among 80 patients with T2DM at District 11 Hospital in Ho Chi Minh City, Vietnam. At baseline, patients were interviewed through a predefined, structural questionnaire to assess their knowledge about hypoglycemia and insulin pen use. After that, patients underwent an individual health education session about hypoglycemia and insulin pen. One month and two months after this intervention, knowledge about hypoglycemia and insulin pen use were recorded again. Results. The majority were males (65.0%) and the mean age was 59.6 (standard deviation 8.1, range 35-75) years. Very few patients had good knowledge and proper insulin pen use, with percentages ranging from 13.8% to 60%. There was a significant improvement of knowledge and practice after the intervention. Such improvement remained high one month and two months after the intervention. Conclusions. The health education intervention is effective in improving knowledge and practice in this population. There is a pressing need for such intervention at primary care hospitals to optimize treatment for patients with T2DM, possibly focusing on those who had characteristics to have the best effectiveness found in this study.

健康教育在提高越南初级保健医院 2 型糖尿病门诊患者低血糖和胰岛素笔使用知识方面的有效性

背景。对低血糖和胰岛素笔使用知识有限的 2 型糖尿病 (T2DM) 患者可能会出现低血糖和其他并发症。客观。本研究旨在评估健康教育对越南一家初级保健医院 T2DM 门诊患者低血糖和胰岛素笔使用知识的有效性。方法. 在越南胡志明市第 11 区医院对 80 名 T2DM 患者进行了一项前测后测研究。在基线时，通过预定义的结构问卷对患者进行采访，以评估他们对低血糖和胰岛素笔使用的了解。之后，患者接受了关于低血糖和胰岛素笔的个人健康教育。本次干预后1个月和2个月，再次记录有关低血糖和胰岛素笔使用的知识。结果. 大多数为男性（65.0%），平均年龄为 59.6（标准差 8.1，范围 35-75）岁。很少有患者有良好的知识和正确使用胰岛素笔，百分比从 13.8% 到 60% 不等。干预后，知识和实践有了显着提高。这种改善在干预后一个月和两个月仍然很高。结论。健康教育干预可有效提高该人群的知识和实践。基层医院迫切需要这种干预措施，以优化对 T2DM 患者的治疗，可能侧重于那些具有本研究中发现的最佳疗效特征的患者。
