Assessment of adherence to medication during chronic illnesses in pregnancy

PURPOSE/AIM: To evaluate adherence to medication in chronic illnesses during pregnancy and to identify factors responsible for non-adherence. METHODS: This was a prospective, cross-sectional, questionnaire based study initiated after approval of the institutional ethics committee. Pregnant women suffering from any chronic illness (except HIV) were questioned to evaluate adherence to medication in chronic illnesses during pregnancy and to detect factors responsible for non-adherence using a semi-structured, open-ended questionnaire. Adherence to medication was also assessed using 4-item Morisky's medication adherence scale. RESULTS: Rate of high adherence was significantly more (58.77%) with medications for chronic illness compared to medications for normal pregnancy (15.78%). Majority of women were more concerned about the chronic illness and believed that keeping the chronic illness under control is more important for normal growth of the baby. Unawareness about usefulness of each medicine and forgetfulness were the most common reasons for non-adherence to medications. Not taking prescribed dose was the most common type of non-adherence. Level of adherence positively correlated with level of education while it was inversely related to number of tablets per day. CONCLUSION: Higher adherence to medications for chronic illnesses during pregnancy is an encouraging finding but at the same time poor adherence to medications for normal pregnancy is a matter of concern. Most of the issues responsible for non-adherence to medication as reported in this study can be resolved to a significant extent by planning and implementing interventions aimed at improving adherence to treatment during pregnancy in which health professionals play a major role.
