Overview
Dataset Summary
The MarketScan Research Databases provide national (though not nationally representative) longitudinal administrative claims data across public and private insurers.
The dataset includes inpatient, outpatient, and prescription drug claims. Private insurance data largely reflect individuals covered through large employer-sponsored insurance programs. Medicare data include beneficiaries with employer-sponsored supplemental coverage, and Medicaid data include beneficiaries from 11 participating states. MarketScan is widely used for analyses of healthcare utilization, treatment patterns, and costs of care.
Caveats
- Not nationally representative; data primarily reflect large employers and select states.
- Medicaid data limited to 11 participating states.
- Medicare data include only beneficiaries with employer-sponsored supplemental coverage.
- Requires costly licensing agreements, limiting accessibility.
- Administrative claims lack detailed clinical variables beyond billing information.
Examples of Outcomes Examined
- Healthcare utilization patterns
- Cost of care and healthcare spending
- Medication adherence and prescription use
- Comparative effectiveness of treatments
- Hospitalization and readmission rates
