Follow-Up Factors Contribute to Immunosuppressant Adherence in Kidney Transplant Recipients.

Purpose:Follow-up and immunosuppressive medication (ISM) adherence are both important for kidney transplant recipients postoperatively and whether follow-up factors affect the ISM adherence remains unclear. The aim of this study was to examine the relationship between follow-up factors and ISM adherence, and the factors associated with ISM adherence. Patients and Methods:An internet-based cross-sectional survey was conducted in a single kidney transplant center in China. The participants completed the internet-based questionnaire and the Basel Assessment of Adherence to Immunosuppressive Medication Scale (BAASIS©) from January 12 to January 26, 2021. Results:Finally, 288 (66.7%) participants responded to this survey. The percentage of full adherence to immunosuppressant was 51.7% (149/288), with 33.3% of the participants reporting a problem in timing dimension. We found that follow-up with a fixed doctor was significantly positive to good adherence (OR=2.124, 95% CI=1.111-4.062, P=0.023) after analyzing the survey data. Time since kidney transplantation and number of non-immunosuppressants were both associated with immunosuppressant adherence. No significant difference was found regarding the effect of the follow-up adherence on ISM adherence. Conclusion:Our study demonstrated an insufficient prevalence of adherence to immunosuppressant in Chinese renal transplant recipients and revealed that follow-up with a fixed doctor may be a way to improve the patients' ISM adherence. This anonymous internet-based survey provides valuable insight into the actual adherence rate, factors associated with non-adherence, and situations that may improve medication-taking.
