Enriching Patient-Level Clinical Trial Data with Representative Socioeconomic Data

With funding support from the Robert Wood Johnson Foundation, Project Data Sphere, LLC (PDS) and RTI International collaborated to enhance the analytical utility of selected datasets hosted on www.ProjectDataSphere.org. Based on Patient Reported Outcomes data captured in the EQ-5D™ index score (derived from the EuroQOL five dimensions questionnaire), RTI identified likely corresponding socio-demographic, access, health, and healthcare related variables captured from the Medical Expenditure Panel Survey (MEPS). These variables include:

  • Socio-demographic factors: Age, race/ethnicity, sex, marital status, employment status, education level, income level, year in MEPS
  • Access related factors: Insurance coverage, ability to obtain necessary medical care
  • Health related: EQ5D, health status, work limitations, smoker status
  • Healthcare related: Office based physician visits, in-patient stays, ER visits, Rx purchases, total expenditures
