This study details the ADHERE Brazil project, a large epidemiological study on kidney transplant patients. It highlights successful data collection and infrastructure building, offering solutions for future research.
Area of Science:
- Nephrology
- Epidemiology
- Clinical Research Logistics
Background:
- Large-scale epidemiological studies face significant financial and operational hurdles.
- The ADHERE Brazil study aimed to address these challenges in kidney transplant research.
Purpose of the Study:
- To describe the planning and execution of the ADHERE Brazil study.
- To detail the study's structure, challenges encountered, and solutions implemented.
- To estimate the prevalence of nonadherence to treatment in kidney transplant patients.
Main Methods:
- A cross-sectional, multicenter study involving 1,105 kidney transplant patients across 20 Brazilian centers.
- Implementation involved coordinated efforts in general, regulatory, data collection, and statistical areas.
- Innovations in logistics were employed for efficient data collection and quality monitoring.
Main Results:
- High-quality data were successfully collected through meticulous planning and execution.
- A robust local research infrastructure was established for subsequent studies.
- Effective communication strategies and data management systems were crucial.
Conclusions:
- The logistical framework developed for ADHERE Brazil provides a model for conducting similar large-scale epidemiological studies.
- The study successfully collected valuable data and built research capacity.
- Alternative strategies for managing complex research projects are presented.
