Stages of Methods Projects

Sentinel develops a wide range of methods to enhance medical product safety assessment.

  • Early-stage methods projects represent truly novel ideas and innovations that require completion of proof-of-concept work.
  • Mid-stage methods projects focus on methodological techniques that have already been shown to be valuable statistically or epidemiologically, but have not been fully applied in the Sentinel Common Data Model (SCDM).
  • Later-stage methods projects use a prototype to inform the development, implementation, and enhancement of production-ready analytic tools.
