Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Over the past decades, survival rates in heart transplantation recipients improved significantly, due to advancements in regimens of immunosuppressives and surgical techniques, but are still limited to the first 12 months post transplantation. Long-term survival remains almost unchanged indicating the need to identify and improve relevant factors. Evidence in other chronically-ill patient populations shows that the healthcare system (e.g. level of chronic illness management (CIM)) and patient self-management (e.g. adherence) drive improvements in outcomes.

The BRIGHT study is the first multi-centre, multi-continental study examining healthcare system and heart transplant centres chronic illness management practice patterns and potential correlates of immunosuppressive medication nonadherence.

The knowledge gained will inform clinicians, researchers and healthcare policy makers about the level(s) interventions need to be implemented at to improve long-term outcomes for transplant recipients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background: After receiving a heart transplant (HTx) patients have to adhere to a number of health behaviors (e.g., medication taking, and smoking cessation) in order to guarantee optimal outcomes. Non-adherence to these health behaviors is associated with poor clinical and economic outcomes. However, the prevalence of non-adherence to these health behaviors is high among HTx recipients. Furthermore, differences in prevalences among countries and continents are observed. The extent to which a HTx recipient is adherent is affected by a variety of risk factors, namely 1) patient-related factors, 2) socioeconomic factors, 3) therapy-related factors, 4) health-related factors and 5) healthcare system and team factors. To-date, this last group of factors only received limited attention in understanding the complex phenomena of adherence.

Aims: The aims of this study are:

1. To describe CIM practice patterns among centres, countries/continents in HTx.
2. To assess the prevalence and variability of nonadherence to treatment regimen, i.e. medication taking, smoking cessation, diet keeping, alcohol consumption, physical activity, sun protection and appointment keeping in HTx recipients among centres, countries/continents.
3. To determine which multi-level factors are related to immunosuppressive medication adherence at the different system levels
4. To benchmark the participating centres, countries and continents in relation to CIM practice patterns and non-adherence to health behaviours

Methodology: The BRIGHT study is an international, multi-center, cross-sectional study. Data were collected using interviews and questionnaires. HTx recipients, nurses working in the post-transplantation care of HTx recipients and the medical directors of the HTx programs were surveyed. The investigators recruited a convenience sample of 36 heart transplantation centers (North America (n= 12), European (n= 19), Australia (n= 2) and South America (n= 3)). Within participating centers, a random sample of patients who met the study eligibility criteria was selected. Per center, a minimum of 20 and a maximum of 60 patients were included. In total, 1677 heart transplant recipients were invited to participate in this study. The questionnaires used in this study will be existing questionnaires (e.g. BAASIS interview to assess adherence with medications, DASS to assess depression) as well as questionnaires developed for this study.

During a regular follow-up visit, patients were invited by a staff person to participate in this study. The staff first informed the patient about the study and, if the patient was willing to participate, retrieved a signed informed consent. Participating in this study was voluntary. Informed consent of the nurses and the medical director of the transplant center were implied by completing the questionnaires. Participant names will be held in strict confidence and will remain anonymous in research reports or publications.

The results of the benchmarking of the parameters assessed in this study will be reported by figures and tables. Because of privacy, the HTx centers can only identify the parameters specific to their center. All other information will be reported anonymously.
