The Health Indicators Warehouse (HIW) is a national database of measurable characteristics that describes health statistics, causal factors of health issues and accessibility and use of healthcare, all of which are considered health indicators.
The Health Indicator Warehouse contains national, state and county-level health indicators, but does not detail or record information of individuals. The HIW allows users to download, tabulate, chart and annotate indicators while reading supporting descriptive data and finding interventions. They also can access links from indicators to information about evidence-based interventions.
Users can search the pre-tabulated indicators by keyword, topic, geography or health-related initiative. The associated descriptive data about indicators helps to facilitate use, interpretation and understanding. The vast collection of over 1700 health indicators and evidence-based intervention information furthers the development and practice of evidence-based medicine.
Developers access HIW through an application programming interface (API) to enable access from different hardware and software platforms and increase compatibility. The data in the HIW is made compatible with the United States government’s Project Open Data.
The HIW is a flagship initiative in the Health and Human Services Open Government Plan. Designed and developed from mid-2009 till early 2011, the first public release of HIW was in February 2011. The Healthcare Consortium recognizes the HIW as a Health Data All-Star.
