A comprehensive stroke center patient registry: advantages, limitations, and lessons learned

Introduction: The use of medical data registry allows insitutions to effectively manage information for many different investigations related to the registry, as well as evaluate patient's trends over time, with the ultimate goal of recognizing trends that may improve outcomes in a particular patient population.Methods: The purpose of this article is to illustrate our experience with a stroke patient registry at a comprehensive stroke center and highlight advantages, disadvantages, and lessons learned in the process of designing, implementing, and maintaining a stroke registry. We detail the process of stroke registry methodology, common data element (CDE) definitions, the generation of manuscripts from a registry, and the limitations.Advantages: The largest advantage of a registry is the ability to prospectively add patients, while allowing investigators to go back and collect information retrospectively if needed. The continuous addition of new patients increases the sample size of studies from year to year, and it also allows reflection on clinical practices from previous years and the ability to investigate trends in patient management over time.Limitations: The greatest limitation in this registry pertains to our single-entry technique where multiple sites of data entry and transfer may generate errors within the registry.Lessons Learned: To reduce the potential for errors and maximize the accuracy and efficiency of the registry, we invest significant time in training competent registry users and project leaders. With effective training and transition of leadership positions, which are continuous and evolving processes, we have attempted to optimize our clinical research registry for knowledge gain and quality improvement at our center.
