J Ayub Med Coll Abottabad Jan ;28(2):302-7.

Background: Diabetes being a serious health issue faced by developing countries with drug adherence having pivot role for recommended glycaemic target. This study aims to determine drug non-adherence in type 2 diabetics and its predictors and associations. Methods: This cross sectional study was conducted after ethical approval at Medicine Dept. Rawal Institute of Health Sciences Islamabad over 10 months duration. Demographic details, duration of diabetes, education, socioeconomic class, glycaemic control, mode of anti-diabetic therapy, number of medications and other modes of therapy documented. Michigan Diabetes Knowledge Questionnaire applied with outcome as good, acceptable and poor knowledge. Drug adherence was assessed by Morisky Medication Adherence Scale (non-adherence at <6 points). Data analysed via SPSS version 17 with significant p-value <0.05. Results: Among 183 diabetics there were 43 (23.5%) males and 140 (76.5%) females. Mean age was 56.6±10.6 years and mean duration of diabetes 8.4±6.57 years. One hundred and fourteen (62%) cases were non-adherent. Diabetes knowledge was poor in 76 (41.5 %), acceptable in 76 (41.5 %) and good in 31 (16.9%). Un-satisfactory glycaemic control present in 149 (81.4%). Non-adherence was found to be associated with poor glycaemic control, poor dietary adherence, poly-pharmacy, illiteracy, practicing other modes of therapy and poor diabetes knowledge (p<0.05). Conclusion: Nonadherence to medication in type 2 diabetics needs to be addressed. Suggested contributory factors are illiteracy, practicing other modes of therapy, poor diabetes knowledge and poly-pharmacy. Public awareness programs, self-monitoring of blood sugars, regular follow-up visits with focus at patient education may improve glycaemic control and diabetes related complications.
