Assessment of the Effectiveness of Patient Education and Interviews in Improving Medication Adherence of Renal Transplant Recipients

Abstract

Background Non-compliance with immunosuppressive drugs has been reported as the most significant cause of graft loss. Since non-compliance with immunosuppressive drugs is preventable, certain approaches based on the risk factors and causes of non-compliance can help eliminate this problem. Aims The purpose of this study is to assess the effectiveness of patient education and interviews in improving medication adherence of renal-transplant recipients. Materials and methods This study was designed as a randomized controlled trial. Using the G*Power program, the sample size was calculated as 60 subjects, with 30 in both the intervention group and control group. Data collection tools included a patient information form, a pretest-posttest, a drug monitoring form for kidney transplant patients, the Immunosuppressive Therapy Adherence Scale, measurement of tacrolimus blood levels, and a training booklet. Results The mean knowledge score in the intervention group was 12.17 +/- 3.39 at baseline, and it increased to 20.73 +/- 1.57 after the intervention. The mean scores on the Immunosuppressant Therapy Adherence Scale were 11.67 +/- 0.55 and 10.70 +/- 0.99 in the intervention group and control group, respectively. There was a statistically significant difference between the pre- test and post-test means on the Immunosuppressant Therapy Adherence Scale in the intervention group. The mean Immunosuppressant Therapy Adherence Scale score was higher in the intervention group. In the measurement of tacrolimus blood levels, medication adherence was found the be higher in the intervention group. The difference between the groups was statistically significant. There was a positive correlation between the tacrolimus blood levels and the Immunosuppressant Therapy Adherence Scale scores in both groups. Conclusions To conclude, our results have demonstrated that patient education and interviews improve immunosuppressant medication adherence in renal transplant recipients. Using direct or indirect methods proved similar outcomes, suggesting that both evaluation methods are safe.
