We sought to evaluate the prevalence of medication understanding and non-adherence of entire drug regimens among kidney transplantation (KT) recipients and to examine associations of these exposures with clinical outcomes. Structured, in-person interviews were conducted with 99 adult KT recipients between 2011 and 2012 at two transplant centers in Chicago, IL; and Atlanta, GA. Nearly, one-quarter (24%) of participants had limited literacy as measured by the Rapid Estimate of Adult Literacy in Medicine test; patients took a mean of 10 (SD=4) medications and 32% had a medication change within the last month. On average, patients knew what 91% of their medications were for (self-report) and demonstrated proper dosing (via observed demonstration) for 83% of medications. Overall, 35% were non-adherent based on either self-report or tacrolimus level. In multivariable analyses, fewer months since transplant and limited literacy were associated with non-adherence (all P<.05). Patients with minority race, a higher number of medications, and mild cognitive impairment had significantly lower treatment knowledge scores. Non-white race and lower income were associated with higher rates of hospitalization within a year following the interview. The identification of factors that predispose KT recipients to medication misunderstanding, non-adherence, and hospitalization could help target appropriate self-care interventions.
