PDS UID: Colorec_Multipl_2006_251
Enhancing the Analytic Capacity of Colorec_AstraZe_2006_78 using a Statistical Linkage Method to Append Socioeconomic and Health Care Access Variables from the Medical Expenditure Panel Survey
Provider Information
Provider Data DescriptionThis data enhancement project seeks to further advance the mission of the PDS platform by enabling new explorations into the potential influence of health care access, socioeconomic factors, and health behaviors on the patient-level efficacy and outcomes data contained in the PDS online service. This was achieved using a statistical linkage method in which patient-level records from PDS dataset, Colorec_AstraZe_2006_78, were matched with colo-rectal cancer survivors from the nationally representative Medical Expenditure Panel Survey (MEPS). Linkage criteria were based on age, sex, race, tumor location, and a quality of life assessment called the EQ-5D index score. The use of the EQ-5D score as a linkage criterion reduces the multitude of many-to-many exact matches that would have occurred using only age, race, and sex. A sixth optional linkage criterion based on BMI category has also been provided so that users may restrict the set of linkages based on age, sex, race, tumor location, and EQ-5D further as desired. The addition of the MEPS data to the patient-level data within the PDS enclave will facilitate hypothesis-generating research efforts that explore the level of variation in patient outcomes potentially attributable to differentials in access to basic health care services and their utilization, to socioeconomic characteristics, and to health behaviors and preferences. It will support exploratory analyses designed to examine questions such as How are variations in cancer patients' access to health care and income impacting patient outcomes in specific phase III clinical trials? What variations in patient outcomes are associated with specific demographic, socioeconomic, and health-related factors? Are the demographic characteristics of those cancer patients enrolled in specific phase III clinical trials comparable to cancer patients with the same disease in the general population?
