INTRODUCTION Geriatric population is more prone for various chronic and recurrent illnesses like diabetes mellitus, hypertension, IHD, arthritic, neurodegenerative, gastrointestinal, ocular, genitourinary, respiratory disorders etc., which may require chronic medication with multiple drugs. Poor compliance in this age group accounts for medication wastage with increased cost of healthcare and substantial worsening of the disease with disability or death. Most of the human and economic costs associated with non adherence can be avoided by improving medication adherence. AIM To assess the level of medication compliance in elderly patients with chronic illnesses and to analyse the factors influencing medication compliance. MATERIALS AND METHODS The study subjects were assessed by using twenty item structured questionnaires as per modified Morisky Medication Adherence Scale (MMAS). RESULTS A total of 251 subjects of geriatric age group with chronic illnesses were assessed for the level of compliance for long term medications. The average number of medications 2.96±1.42 per subject and most of the subjects were receiving FDCs. The compliance level was assessed by way of interview using a twenty item structured pretested questionnaire as per modified MMAS. The level of compliance was good in 45.41%, moderate in 35.45% and poor in 19.12% of the study subjects. CONCLUSION The level of compliance positively correlated with the educational status of the study subjects and their awareness about the diseases and prescribed medications. The overall level of compliance was higher in subjects living with spouse or families, subjects without any functional impairment, subjects who were regular for the follow-up visits and also in subjects who did not experience any adverse events.
