From Data to Action

About the Data

 

Data from Neighborhood Health Partnerships (NHP) is a valuable resource designed to complement your understanding and knowledge of your local community. The resources available on this site are provided through comprehensive reports and interactive maps, offering actionable insights into health outcomes and care in your neighborhood.

Data in Our Reports

The data used in the reports comes from multiple sources including the Wisconsin Collaborative for Healthcare Quality (WCHQ), the U.S. Census Bureau American Community Survey (ACS), and the CDC Behavioral Risk Factor Survey (BRFS).

The Wisconsin Collaborative for Healthcare Quality (WCHQ) is a voluntary collaborative of health systems, medical clinics, and dentists in Wisconsin. WCHQ members publicly report health outcome and care measures on the WCHQ website and work on quality improvement teams to improve the quality and affordability of healthcare and promote health in Wisconsin. WCHQ member organizations (i.e. clinics and health systems) submit data to WCHQ that was recorded in electronic health records during primary care visits. This includes information about vaccinations, screenings for cancer and other health risk factors, and management of diabetes and heart disease. The health systems provide these data, while protecting patient confidentiality, for the NHP reports.

More information about this data source is available at the link below:

WCHQ data is used in the Health Outcomes and Care Reports to report different health measures at the ZIP code level.

Limitations to WCHQ Data

  • Because the data only includes health systems that are members of WCHQ, the estimates based on these data do not reflect the entire population of the ZIP code. People living in the ZIP code who do not receive care at a WCHQ member health system are not included in these data. This includes people who get their healthcare elsewhere, those who do not have access to healthcare, and those who simply have not had a primary care visit in the last one to three years.
  • Some of the WCHQ measures rely on patients who have received a formal diagnosis. People who have conditions such as diabetes or heart disease that do not yet have a formal diagnosis are not accounted for in these measures.
  • Some of the population sizes represented in the reports are small. This means that small fluctuations in healthcare, outcomes, and behaviors could have a large impact on the measure results. For example, if the population of people included in a report is 50 people, 15 of whom are smokers, just a few people quitting smoking may have a dramatic-looking impact on your reports.
  • Health system data may include duplicate patient records if a patient receives care from more than one system.

The U.S. Census Bureau American Community Survey (ACS) is the premier source for detailed population and housing information in the U.S. It is an ongoing survey that provides information on a yearly basis about demographics, jobs, education, housing, and more for people living in the United States and Puerto Rico. More information about this data source is available at the links below:

ACS data is used in every report. In the Health Outcomes and Care Reports, the data is used for population size and demographic information. The Social Determinants of Health Reports use ACS data for all the living condition measures and demographics in the reports.

The CDC Behavioral Risk Factor Survey (BRFS) is part of a national system of telephone surveys that collect data from U.S. residents about their health-related risk behaviors, chronic health conditions, and use of preventive services. BRFS randomly selects cell phone and landline users to participate in the survey.

Data from the CDC BRFS from 2011-2017 was used in the Health Outcomes and Care Reports to calculate prevalence estimates of heart disease, hypertension and diabetes in Wisconsin ZIP codes. See the Health Outcomes and Care Reports section of the FAQs on the Reports page for more information.

Social Determinants of Health Reports

Data

The Social Determinants of Health Reports use only U.S. Census American Community Survey (ACS) data.

 

Measures

The ACS data is the premier source for detailed population and housing information in the U.S. Currently, 17 measures are included in the Sociodemographic Profile Reports.

The living conditions in the Sociodemographic Profile Reports were chosen based on the Bay Area Regional Health Inequities Initiative (BARHII) framework and measures available in the ACS data.

The demographics in this report were included to show characteristics of the people living in an area.

Interpreting Data in Context

Datasets—a collection of related items of data—are always incomplete. Any single dataset tells us only part of the story relating to the health of a community and the factors that shape health outcomes and care. Therefore, your data may show an inequity in a health outcome or care and leave you to interpret this inequity.

An example of one common health inequity that may be visible in NHP data is the burden of diabetes among people of color. The data in your report may show a ZIP code with a large population of people of color that has low rates of blood sugar control amongst people with diabetes. However, the NHP reports do not speak to factors that can influence the prevalence of diabetes (such as food availability or cost and access to living wage jobs) and diabetes management (such as access to culturally appropriate care and the presence of medical implicit bias).

Without recognizing the factors that shape health inequities when we use datasets, we risk drawing conclusions about communities that could be untrue and harmful. Here are suggestions to consider when interpreting NHP report data:

  1. Recognize what is and is not represented in the data
  2. Take caution not to draw conclusions from the data that might reinforce harmful and limiting stereotypes about communities
  3. Engage community knowledge and the expertise of those represented in the data
  4. Use frameworks and resources to identify contextual factors that may shape what you see in the data
