Rate of Nonadherence to Antipsychotic Medications and Factors Leading to Nonadherence among Psychiatric Patients in Gondar University Hospital, Northwest Ethiopia

Objective. The main aim of this study was to assess the rate of medication nonadherence among psychiatry patients at University of Gondar Hospital. Materials and Methods. Cross-sectional, descriptive method was conducted over a period of one month in May, 2013, at University of Gondar Hospital. Rate of nonadherence was computed using Medication Adherence Rating Scale questionnaire and self-reporting via a structured patient interview. Chi-square was used to determine the statistical significance of the association of variables with adherence. Result. Out of 209 respondents, 105 (50.2%) were found to be nonadherent. Patients who were forced to take their medication against their will (P<0.001), those who did not believe they require medication (P=0.026), and those who discontinued their medication without consulting their prescriber (P<0.001) had significant association with nonadherence. Adherence among schizophrenia was 75.7%; psychotic was 46.7%; bipolar disorder was 37.5%; and psychosis with depression was 52.6%. Reasons for nonadherence included recovery from the illness (26.7%), seeking alternative therapy and unavailability of drugs (18.1% each), adverse drug reaction (12.7%), forgetfulness (10.6%), and being busy (8.6%). Conclusion. The observed rate of antipsychotic medication nonadherence in this study was high. Interventions to increase adherence are therefore crucial
