SHADAC's State Health Compare
Analysts and policymakers can use State Health Compare to view measures of insurance coverage, access, cost, utilization, and outcomes—as well as social and economic measures related to health. State Health Compare allows users to compare these measures across states and look at trends over time through user-generated maps, bar charts, trend lines, and tables. Users can also explore these measures within states by characteristics (e.g., age, race/ethnicity, and education level). There are currently over 50 measures drawn from 16 data sources available on State Health Compare, drawn from the most currently available data, and estimates are available for timespans ranging between 2 and 20 years. SHADAC also provides ongoing updates to 16 of the measures maintained by the Robert Wood Johnson Foundation (RWJF) on its Building a Culture of Health website.

On-Demand Analysis of Federal Survey Data
On a task-by-task basis, SHADAC conducts quantitative analyses for the Medicaid and CHIP Payment and Access Commission (MACPAC) using a broad array of federal survey data, including the American Community Survey (ACS), National Ambulatory Medical Care Survey (NAMCS), National Electronic Health Records Survey (NEHRS), National Health Interview Survey (NHIS), National Survey of Children's Health (NSCH), National Survey on Drug Use and Health (NSDUH), Medical Expenditure Panel Survey (MEPS), Pregnancy Risk Assessment Monitoring System (PRAMS), and the Survey of Income and Program Participation (SIPP), among others. As part of this work, SHADAC assists MACPAC in scaling work to meet their information needs, producing sound estimates, and developing documentation that supports the reproducibility of results over time. Key SHADAC staff execute diverse statistical methods ranging from simple descriptive statistics and t-tests to multivariate logistic regression and maintain Special Sworn Status to facilitate access and use of restricted data at the Minnesota Census Research Data Center (MnRDC).

IPUMS Health Surveys (2006-Present)
Since the early 2000s, SHADAC’s Director has led an effort to harmonize the data and documentation produced by the NHIS, which was expanded in 2016 to include the MEPS. The IPUMS Health Survey project allows users to create free, individual-level customized data extracts for analysis to support time trend analysis through consistent variable coding and production of publically available microdata. This work involves the creation of more than 2,000 integrated variables with comprehensive metadata, and through this work SHADAC has developed expertise and a deep understanding of the publically available NHIS and MEPS data, supporting our work using NHIS restricted data in the RDC.
