Healthcare Databases

Our experts look forward to collaborating with you for all your analytical research needs, including utilizing healthcare databases. We provide guidance on data available from databases, their usage, and techniques for handling complex survey weights.

The Department of Quantitative Health Sciences (DQHS) utilizes large healthcare databases to promote health-related research in support of furthering our knowledge in healthcare. DQHS has developed an infrastructure resource with a catalog of such databases on the DQHS website aided by grants PIKO (MPI: K. Kaholokula, U54GM138062) and Ola HAWAII (MPI: J. Hedges, N. Mokuau, U54MD007601) to support biomedical and healthcare researchers in Hawaiʻi.

If you are interested in conducting collaborative research using healthcare databases, please feel free to contact us for more details.


Recommended Databases for Secondary Data Analysis

IPUMS is one of the largest accessible databases of census microdata from the U.S. and other countries. In the past, IPUMS was initially an acronym for Integrated Public Use Microdata Series. However, the IPUMS database has grown beyond projects with microdata to include harmonized survey data from health, education, and labor force surveys. IPUMS is now known as the name of this large data warehouse that is a part of the Institute for Social Research and Data Innovation at the University of Minnesota.

The Behavioral Risk Factor Surveillance System (BRFSS) is a cross-sectional health-related telephone (landline and cellular) survey that collects state data about United States residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services.

The National Health and Nutrition Examination Survey (NHANES) is a survey research program conducted by the National Centers for Health Statistics (NCHS), designed to assess health and nutritional status of adults and children in the United States.

The National Health Interview Survey (NHIS) is an annual, cross-sectional household interview survey program designed to monitor trends in illness and disability. It can also be used for epidemiologic and policy analysis by the public health research community, tracking progress toward achieving national health objectives, determining barriers to accessing using appropriate health care, and evaluating federal health programs.
