Patients who receive a kidney transplant arrive at the abdominal transplantation surgery ward after surgery. Within 10-14 days they learn which anti-rejection medication they have to take, how they have to take it and to what they have to pay attention. This learning process is attended by the nurses of the ward.
It is already known that a bad medication adherence is related to a higher rejection rate and mortality of patients who receive a kidney transplant. Bad medication knowledge and low health literacy are correlated with a bad medication adherence. Data about the level of health literacy of the Belgian population (and certainly of patients who just received a kidney transplant) are scarce.
The main purpose of this study is to have an idea of the extent of medication knowledge, heath literacy and adherence in patients who received a renal transplant.
Therefore, a prospective cohort study will be performed. Adult patients admitted for a renal transplantation, will be included after obtainment of informed consent. The patients will be followed for 2 years. On predefined time points, the participants will have to fill in questionnaires and tests: on discharge 2 tests that measure health literacy, the "Basel Assessment of Adherence to Immunosuppressive Medications Scale" (BAASIS), the medication knowledge test and a questionnaire about demographic factors. At 1 month post-transplantation the BAASIS test and medication knowledge test, 3 months post-transplantation the 2 tests assessing health literacy, the BAASIS test and medication knowledge test and finally after 1 and 2 years all the tests (4 in total) and questionnaire assessing demographic factors

Admitted for renal transplantation
Patients who are hospitalised on the abdominal transplantation surgery ward at the University Hospitals of Leuven (UZLeuven) and undergo a kidney transplantation during this hospitalisation.
Intervention: taking questionnaires and tests at predefined timepoints:
Other: Taking questionnaires and tests
At predefined timepoints:
- Degree of medication knowledge pre-and post kidney transplantation as measured by the self-edited medication knowledge test [ Time Frame: Up to 36 months ]Measurement: quantitative score
- Degree of health literacy pre- and post kidney transplantation as measured by the NVS-D and FCCHL test [ Time Frame: Up to 36 months ]
Measurement: NVS-D = quantitative score (max = 6 points) with 3 groups: low health literacy = 0-1; intermediate health literacy = 2-3; high health literacy = 4-6.
The FCCHL contains 3 subitems (functional, communicative and critical health literacy) Each subitem contains 4 questions. Each question is rated on a 4-point scale, ranging from 1 to 4 (4 indicating high health literacy). The scores for the items in a scale are summed and divided by the number of items in the scale to give a scale score (theoretical range 1-4).
- Degree of medication adherence pre- and post kidney transplantation assessed by the BAASIS test [ Time Frame: Up to 36 months ]Measurement: BAASIS = 4 questions assessing adherence. If the patient answers 'no' on at least 1 question, the patient is categorized as 'non-adherent'.
- Type of evolution in the degree of medication knowledge (assessed by self-edited test, see above), health literacy (assessed by NVS-D and FCCHL, see above) and/or medication adherence (assessed by BAASIS, see above). [ Time Frame: Up to 36 months ]Is their a positive or negative evolution in medication knowledge, health literacy and/or medication adherence at discharge-1month-3 months-1 year-2 years after kidney transplantation?
- Correlation between degree of medication knowledge, degree of health literacy and/or degree of medication adherence [ Time Frame: Up to 36 months ]
- Correlation between evolution of medication knowledge, evolution of health literacy and/or evolution of medication adherence [ Time Frame: Up to 36 months ]
- Defining risk factors (assessed by the demographic questionnaire) related to the degree of medication knowledge, health literacy and/or medication adherence [ Time Frame: Up to 36 months ]
- Defining risk factors (assessed by the demographic questionnaire) related to the evolution of medication knowledge, health literacy and/or medication adherence [ Time Frame: Up to 36 months ]
- Correlation between the degree of medication knowledge, health literacy and/or medication adherence, and outcome parameters (trend of serum creatinine, result of biopsy of kidney transplant, trend and variation of tacrolimus' trough level) [ Time Frame: Up to 36 months ]
- Correlation between the evolution of medication knowledge, health literacy and/or medication adherence, and the outcome parameters (trend of serum creatinine, result of biopsy of kidney transplant, trend and variation of tacrolimus' trough level). [ Time Frame: Up to 36 months ]
