Abstract:
BACKGROUND: Information on adherence of adult psychiatric patients to biological modes of
treatment is scarce in Ethiopia. Knowledge on adherence is essential in terms of future prognosis, quality
of life and functionality of such patients. This study was conducted to assess the magnitude and
associated factors of non-adherence to medication.
METHODS: A hospital based cross-sectional study was conducted in November 2011 at the psychiatry
facility of Jimma University Specialized Hospital, which provides service to more than 10 mill people. A
sample of 422 adults with psychiatric illness in the follow-up outpatients was selected consecutively. Data
was collected using a pre-tested questionnaire by face-to-face interview and from patient medical records.
The four-item Morisky scale was used to assess degree of medication adherence. Data was analyzed
using SPSS version 16 and descriptive, chi-square test and logistic regression statistical methods were
used. P-Value of less than 0.05 was considered as statistically significant in the final model.
RESULTS: Out of the 422 patients, 40.3% were females and 59.7% males. The prevalence rate for nonadherence was 41.2%, non-affective psychoses diagnosis contributing the highest rate (44.5%). From the
total non-adherent respondents, 78.2% attributed their non-adherence to forgetting. Irregular follow-up,
poor social support and complex drug regimen were independently associated variables with nonadherence.
CONCLUSIONS: The result of the study showed that non-adherence among psychiatric patients in
Southwest Ethiopia is high and revealed possible associated factors. Adherence needs integrated efforts
in creating a mechanism in enhancing regular follow-up, informal social support system and ongoing
awareness creation among professionals.
