Claims-Based Enumeration Sampling (CBES): Utilizing Administrative Claims Data as a Sampling Frame for Patient Experience Surveys

Evidence-based policymaking increasingly demands integrating real-world data with patient perspectives.

This study introduces Claims-Based Enumeration Sampling (CBES), a methodology utilizing administrative claims data as a sampling frame to substitute for clinical registries.
