Management Practice, and Adherence and Its Contributing Factors among Patients with Chronic Kidney Disease at Tikur Anbessa Specialized Hospital: A Hospital Based Cross-Sectional Study

The objective of this study was to assess the management practice, medication adherence, and factors affecting medication adherence in CKD patients at Tikur Anbessa Specialized Hospital (TASH). Methods. A cross-sectional study was conducted at the nephrology clinic of TASH. A total of 256 CKD (stages 1 and 2=50, stage 3=88, stage 4=55, and stage 5=63) patients were recruited through systematic random sampling. Data were collected from medical records and interviewing patients. The rate of adherence was determined using 8-item Morisky medication adherence scale. The data were analyzed using SPSS version 20.0 statistical software. Univariate and multivariate binary logistic regression were used to investigate the potential predictors of medication nonadherence. Results. About 57.3% of diabetes mellitus with hypertension were treated with combination of insulin and ACEI based regimens. Other cardiovascular comorbidities were predominantly treated with Acetyl Salicylic Acid in combination with β-blocker. Only 61.3% (stages 1 and 2=70%, stage 3=73.9%, stage 4=54.5%, and stage 5=43%) of the study population were adherent to their treatment regimens. Forgetfulness (79.8%) was the major reason for medication nonadherence. Patients who had an average and high monthly income were 4.14 (AOR=4.14, 95% CI: 1.45-11.84, p=0.008) and 6.17 times (AOR=6.17, 95% CI: 1.02-37.46, p=0.048) more likely to adhere as compared to those who had very low income. Patients who were prescribed with ≥5 drugs were 0.46 times (AOR= 0.54, 95% CI: 0.27-1.10, p=0.049) less likely to adhere compared to their counterpart. Patients who were students, drivers, or teachers working in private school were about 7.46 times (AOR=7.46, 95% CI: 1.49-37.26, p=0.014) more likely to adhere compared with patients who were farmers. Conclusion. Insulin and ACEIs based regimens were the most frequently used regimens in the treatment of diabetes mellitus and hypertension comorbidities. Very low income, increased number of prescribed medications, and being a farmer were the predictors of medication nonadherence.
