We were entrusted with the implementation of Post-Marketing Surveillance, including the creation of implementation guidelines, survey forms, facility contracts, patient enrollment, data management, statistical analysis, medical writing, and system development (EDC, progress management systems, etc.). We established a project manager to centrally manage the outsourced tasks and implemented strategies for the smooth progress of the surveys. This included devising and executing measures to address issues (such as approaching facilities experiencing progress delays, implementing measures to control re-surveys, etc.), ensuring high-quality and efficient survey operations.
