Study summary

Non-adherence is widespread in the transplant community. Addressing issues associated with non-adherence remains a key challenge in transplantation, in part due to the difficulty in assessing its prevalence, as there is currently no 'gold standard' for use in routine clinical practice.

The purpose of this study is to evaluate the non-adherence to immunosuppressive therapy, including tacrolimus once-daily, among Italian kidney transplant recipients receiving. Along with non-adherence evaluation, possible factors related to NA will be investigated (patient-related, condition/disease-related, therapy/treatment-related, etc.).

What researchers measure

Primary outcomes

  1. Non aderence

    Proportion of non-adherent patients to immunosuppressive therapy as measured by the Basel Assessment of Adherence with Immunosuppressives Scale (BAASIS©-interview). The BAASIS© consists of four items (with a 6-point scale for responses ranging from never (0) to every day (5)) measuring patients' taking, skipping (or drug holidays), timing (\>2 hrs from prescribed time) and dose reduction of drugs. An affirmative answer to any of the first 4 questions results in assignment to the non-adherent group.

    Time frame: 6 months

Secondary outcomes

  1. BMQ score

    Describe the patient's belief about immunosuppresive medicines, as measured by the Belief about Medicines Questionnaire (BMQ). It is an 18-item measure comprising of two subscales (general harm and general overuse), and two subscales (specific necessity and specific concerns). Higher scores in the General-Harm and General-Overuse sub-scales represent an overall negative perception of medication. High scores in the Specific-Concerns sub-scale means that adverse reactions are potentially harmful and high scores in the Specific-Necessity sub-scale are indicative of the patient's need to adhere to medication to maintain health.

    Time frame: Baseline and 6 months

  2. ACCEPT score

    Describe the patient's acceptance toward immunosuppressive treatment, as measured by the ACCEPT questionnaire. It is a 32-items self-administered questionnaire and covers patient's opinion on: convenience of the medication, length of treatment, constraints due to medication, side effects and a general opinion on the medication. The score ranges from 0 (no acceptance) to 100 (maximum treatment acceptance).

    Time frame: Baseline and 6 months

  3. BAASIS evaluation

    Perform the BAASIS assessement.The BAASIS consists of four items (with a 6-point scale for responses ranging from never (0) to every day (5)) measuring patients' taking, skipping (or drug holidays), timing (\>2 hrs from prescribed time) and dose reduction of drugs. An affirmative answer to any of the first 4 questions results in assignment to the non-adherent group.

    Time frame: Baseline

  4. Patients characteristics

    Describe patients characteristics (such as socio-demographics, lifestyle information, relevant comorbidities, concomitant medications, clinical characteristics information like e.g. primary kidney disease diagnosis, waiting time before graft, transplant characteristic e.g. type of donor, etc.

    Time frame: Baseline

  5. Clinical informations as for clinical practice

    Collect clinical information (e.g. routine tacrolimus trough levels, eGFR if available)

    Time frame: Baseline and 6 months

  6. Immunosuppressive treatments

    Immunosuppressive treatments description and changes

    Time frame: Baseline and 6 months

  7. Rejections

    Occurrence of rejection episodes

    Time frame: Baseline and 6 months

  8. Graft failure

    Occurrence of graf failure

    Time frame: Baseline and 6 months

  9. Adverse events

    Number of adverse events

    Time frame: Baseline and 6 months

  10. Infections

    Occurrence of infections

    Time frame: Baseline and 6 months

  11. Healthcare cost

    Assess the healthcare cost (ER admission, hospitalizations)

    Time frame: 6 months
