The incidence of diabetes has been increasing at a startling rate in India, moreover one in six people with diabetes in the world. The purpose of this study was to assess the knowledge, attitudes and practices (KAP) of patients regarding diabetic and effective management of disease prognosis. A Prospective observational study was conducted in Kovai Medical Center and Hospital, a multispecialty hospital in 2016. Outpatients were provided with a validated KAP questionnaire encompassing closed-ended queries. The responses were scored and analyzed to develop an appropriate counseling program. Pharmacist counseling sessions were carried out in the regional language for 10- 15 minutes. A total of 200 patients were screened, 120 patients fulfilled the inclusion criteria. The socio-demographic shows the incidence of diabetes was more prevalent among males 62.5% and 60% of the population were within the age group of 51- 70 years. Educational background and the duration of insulin usage cannot be consistently linked to high health literacy. KAP scores improved significantly (p < 0.05) after counseling as compared to the first visit. 23.3% of subjects had occasional hypoglycemic and was significantly reduced to 5 %. At the final visit the drop in mean FBS (mg/dL), RBS (mg/dL) and HbA1C levels from 177.30 to 138.91, 249.85 to 177.66 and 9.47 to 7.88 respectively (p< 0.05). The study advocates that the pharmacist intervention has improved the perception of disease, insulin usage, and lifestyle changes that facilitated to achieve the best possible level of glycemic control and quality of life.
