Dear Sir,I have read with interest the article titled, ‘Educational program for patients with type-1 diabetes mellitus receiving free monthly supplies of insulin improves knowledge and attitude, but not adherence,’ Vimalavathini et al.[1] The authors mention in the second paragraph of introduction, “When a patient does not respond to an appropriately prescribed medicine, the reasons could be drug or patient-related factors”. I agree, but at the same time I want to add that, the reasons could also be communication-related factors. The authors already mention in the third paragraph that, “Planned interventional education programs have shown to provide a positive impact on improving the KAP scores in diabeticpatients”.Education is a broad concept, which encompasses both teaching and learning. Evidence-based studies show that doctors' interpersonal and communication skills have a significant impact on improved health outcomes.[2-4] To provide comprehensive care, many key qualities are essential, which include the ability to communicate effectively with the patient, act in a professional manner, cultivate an awareness of one's own values and prejudices, and provide care with an understanding of the cultural and spiritual dimensions of the patient's life.[5]Quality drugs, discipline, and diet (3D) are the principles of diabetic management. However, patients' adherence, compliance with medication, and disease outcome are closely associated with the quality of communication and a planned interventional education program.
