OBJECTIVES: Nonadherence to immunosuppressive drugs is a concern among kidney transplantation recipients (KTRs). The adverse effects of immunosuppressive drugs can trigger nonadherence and lead to a great impact on the allograft survival. The aim of this prospective controlled study is to determine the major adverse effects of immunosuppressive drugs and their correlation with the nonadherence in kidney transplantation recipients. METHODS: All data were collected from medical and pharmacy records. We use modified Immunosuppressant Therapy Adherence Scale combined with Modified Transplant Symptom Occurrence and Symptom Distress scale to explore the relationship between symptom experience related to side effects of immunosuppressants and adherence. The risk of nonadherence was estimated by stepwise logistic regression while controlling for age, gender, education, and immunosuppressive medications. Multivariable analysis was performed using a single random effect of P < .2. RESULTS: In total, 412 KTRs completed the structured self-report instrument. The weekly pill counts were 84.2 ± 39.8. Overall, 21.4% of patients were nonadherent to immunosuppressive drugs. The most common adverse effects of immunosuppressive drugs were memory impairment (28.4%), insomnia (26.0%), gastrointestinal discomfort (21.4%), easy fatigue (22.1%), hand tremor (23.8%), and vision variation (29.1%). Multivariate analysis revealed that the adherence increased in patients with awareness of memory impairment (odds ratio 2.320, 95% confidence interval: 1.259-4.274, P = .007). There was no significant difference in the incidence of acute rejection, gender, age, and education between adherent and nonadherent patients. CONCLUSION: In summary, these results indicate a significant prevalence of nonadherence to immunosuppressive drugs in kidney transplantation recipients. Awareness of memory impairment significantly affected adherence to immunosuppressive drugs.
