Abstract
BackgroundInsulin injection technique re-education and diabetes knowledge empowerment has led to improved glycemic control. ObjectivesTo evaluate the impact of pharmacist’s monthly re-education on insulin injection technique (IT), lipohypertrophy, patients’ perception on insulin therapy and its effect on glycaemic control. MethodsThis randomized controlled, multi-centered study was conducted among type 2 diabetics from 15 government healthclinics. 160 diabetics with baseline HbA1C ≥ 8% and unsatisfactory IT technique were randomized into control or intervention group. Control group received standard pharmacist counselling during initiation and at 4th month. Intervention group received monthly counselling and IT re-education for 4 months. Assessment of diabetes, IT knowledge, adherence and perception towards diabetes were conducted using validated study tools Insulin Treatment Appraisal Scale (ITAS) and Medication Compliance Questionnaire (MCQ)). Results139 patients completed the study; control group (69), intervention group (70). In control group, all outcomes shown improvement except for patient’s perception. Mean HbA1C decreased 0.79% ± 0.24 (p = 0.001). In intervention group, all outcomes improved significantly. HbA1c reduces significantly by 1.19% ± 0.10 (p < 0.001). Monthly re-education improved patient’s perception towards insulin therapy (ITAS score reduced 1.44 ± 2.36; p = 0.021). Between groups, interventional arm shown significantly better improvement in all outcomes. Improvement was shown in IT technique (+2.02 score; p < 0.001), medication adherence (+1.48 score; p < 0.001) and ITAS (−1.99 score; p = 0.037). Mean HbA1C reduced an additional of 0.63% (p = 0.008) compared to control arm. ConclusionRe-education is more effective in increasing adherence, reducing lipohypertrophy, improving injection technique and patient’s perception on insulin therapy, thereby providing better glycaemic control.
