The document discusses improving comparative effectiveness research to make it more patient-centered. It focuses on matching research questions to the most appropriate research methods to provide patient-centered answers. It also emphasizes engaging patients, caregivers, clinicians, administrators, commissioners, and policymakers throughout the entire research process.
