National Immunization Awareness Month

In 1796, the first vaccine was administered to protect the populace against smallpox. Since then, researchers and scientists have developed and tested a multitude of vaccines against diseases such as cholera, yellow fever, tuberculosis, polio, measles, Lyme disease, and hepatitis A. These preventive measures are a way of cutting down the risk of contracting fatal pathogens. Vaccines work by building up your immune system so that if and when you are exposed to pathogens, your body is prepared to fight against it. Being inoculated against a particular illness not only bolsters your protection, but also that of those around you.

Sponsored by the Centers for Disease Control and Prevention (CDC) and coordinated by the National Public Health Information Coalition, National Immunization Awareness Month (NIAM) is held every August to highlight the importance of vaccination. The Public Health Foundation cites three key points that the NIAM campaign focuses on:

  1. vaccines are important in protecting people against disease
  2. vaccines are recommended for all stages of one’s life, and
  3. having a reliable health care provider who is knowledgeable is integral in making sure people get the vaccines they need.
Throughout the NIAM campaign, each week in August targets a specific theme. The first week focuses on babies and pregnant women, the second on children, pre-teens, and teens, followed by young adults in the third week. The last week during NIAM is dedicated to promoting vaccines among adults.

HealthLandscape, in collaboration with the Health of the Public and Science (HOPS) division of the American Academy of Family Physicians, has created an Immunizations Mapper. This mapping application displays state level immunization information for legislative purposes. It is grouped into three main topics covering vaccine-specific coverage levels for children 19-35 months, adolescents 13-17 years, and influenza/pneumococcal vaccination coverage. Users can select a variety of vaccines to display the coverage rate for DTaP, MMR, Varicella, Tdap, HPV, and influenza and streptococcus pneumoniae. When users click on the data table feature of the application, they can view data on which states have the authority to operate an Immunization Information System (IIS) for adults or children, reporting requirements, whether children and adults can opt out via a consent form, and the state registry website.

HealthLandscape users can also find vaccine related measures in Community HealthView, our extensive data library for state and county level data on topics ranging from demographics to veterans to chronic health to economics. Users will find several indicators related to vaccine coverage including percentage of the population 65 and over with an influenza vaccine in the past year and percentage of the population 65 and over that ever had a pneumococcal vaccine. Both of these indicators are from the Behavioral Risk Factor Surveillance System (BRFSS) for data years 2006-2012.

Legislators, health professionals, and public health experts can use tools like HealthLandscape’s Immunizations Mapper and Community HealthView during the NIAM campaign to pinpoint areas to target resources and to collect information on current legislation as they relate to vaccine coverage.

Celebrating Health Center Week

National Health Center Week (NHCW) is an annual time to celebrate the nation’s health centers which serve as health homes to over 28 million otherwise underserved patients. Health centers are incubi for innovations to serve the whole patient including their social determinants of health (SDOH). For NHCW, August 4-10, 2019, every day has a different theme within which we can honor the health centers that are rooted in the communities they serve - within and outside of the clinic walls.

Today, Sunday, August 4, the theme is Social Determinants. SDOH have been shown to have a larger impact on personal health than medical care, genetics and health behaviors. Growing awareness of the impact of SDOH has led to calls by federal agencies to include SDOH in health care decision-making and payment as well as patient risk stratification. The National Academy of Medicine included 17 social and behavioral domains of SDOH data (“neighborhood” data is the only domain that is not individual-level data) to capture in EHRs as a part of Meaningful Use, and many organizations have developed tools to help organizations capture those data. Other organizations, like HealthLandscape, use data from secondary sources which tell us a lot about the neighborhood where a person lives, therefore already filling in much of the picture without needing to capture data on all 16 individual-level domains, or adding to the picture in other cases.

But the question remains - what do we do with these data once they are captured and added to the EHR? Who needs those data? What will they look like? How do we integrate them with clinical data? Most solutions are still focused on the individual patient - connecting patients to resources and providing referrals - but what about the population health targets like payment reformation and patient-risk stratification? HealthLandscape is working on these and other questions related to the addition of these data to EHRs. In our Community Vital Signs suite of tools we have many different visualizations of patient data - both clinical and community data - so we can test and improve the inclusion of SDOH in health care to improve population health. Visit our Population Health Profiler to see one example of these tools.

In the meantime, our other mapping tools like the UDS Mapper and others allow you to quickly visualize (without full EHR integration) how SDOH affect communities. Within the UDS Mapper we provide ZIP Code-level SDOH. Users can explore their communities and see where there are pockets of need, identify areas for growth, and plan to meet community needs. Health centers have always been rooted in communities, and the UDS Mapper is the tool that helps visualize need in those communities.

If you have questions, or would like assistance with any of the HealthLandscape tools mentioned above, please contact us anytime.

National HIV Testing Day

HIV testing day is June 27. On this day, organizations throughout the U.S. sponsor a wide variety of events, including free testing and education.  As HRSA’s Health Center Program funds 10,000 health center sites, serving over 24 million people, it is uniquely situated to address the HIV crisis. In fact, the health center program focuses on care for underserved and vulnerable populations, the same populations disproportionately affected by HIV.  One way the health center program is leveraging this is by participating in the Department of Human Services’ “Ending the Epidemic: A Plan for America.” This new 10-year initiative aims to virtually eliminate new HIV infections in the U.S. by focusing on early diagnosis, rapid treatment, proven prevention, and rapid outbreak response among areas most at risk. When the initiative begins next year, health centers in target areas will expand outreach as well as both routine and risk-based HIV testing opportunities.

As a geographer, I was curious about the communities targeted by the Ending the Epidemic initiative and the health centers located within them. I wanted to visualize the service areas of these health centers in relation to other community resources and overlay some population health data. To get started, I created a series of maps of Franklin County, Ohio, one of the initiative’s 48 target counties, using the UDS Mapper.

The UDS Mapper is ideal for this type of project as it is an online mapping and decision-support tool driven primarily by patient location data within the Uniform Data System (UDS). It allows easy visualization of health center service areas, along with patient data, population health data, and health related facilities. Within the UDS Mapper, I started by navigating to Franklin County, Ohio, then activating the By Patient Origin mode of the Explore Service Area tool.

UDS Mapper with Explore Service Area tool set to By Patient Origin mode

I could see right away that there are five organizations located within Franklin County. I wanted to see how large their service areas are and where they overlap.

I clicked on each organization which added its core, in this case 75%, patient origin service area to the map. I could see that these organizations serve many Franklin County ZIP Code Tabulation Areas (ZCTAs), especially those in and adjacent to the city of Columbus.
Patient origin service areas

I turned on service access points and saw that they are also mostly concentrated in central Franklin County.
Patient origin service areas with health center service access points

For demonstration purposes, I chose Columbus Neighborhood Health Center (CNHC) to examine further. I de-selected the other health centers so my map only showed CNHC’s patient origin service area, then I opened the Data Table. Studies show that people with health insurance have greater access to HIV testing, and that early knowledge of one’s HIV status reduces HIV-related morbidity and mortality and reduces the risk of transmission (KFF, 2019). To assess population insurance status and access to care for CNHC’s service area, I added uninsurance and no usual source of care data to my table. I could see at a glance that in the ZCTAs that comprise CNHC’s core service area, 9% of the population are uninsured and 19% have no usual source of care.

Data table and summary row

I then used the Population Indicators tool to see which ZCTAs are at or above these service area benchmarks.

ZCTAs with relatively high rates of uninsurance and no usual source of care

Twelve ZCTAs within the health center’s service area have uninsured rates above 9% and more than 19% of the population without a usual source of care. These ZCTAs might be ideal areas in which to focus the initiative’s early outreach efforts.

I also wanted to see what other health resources are nearby. There are four opioid treatment programs which could serve as ideal partners throughout the initiative. This is important as intravenous drug use is a major risk factor for HIV transmission, and drug use in persons with HIV could exacerbate the progression of the virus (NIDA, 2018). Additionally, there are several hospitals and public housing facilities within CNHC’s service area which could serve as potential HIV care collaborators.
Health centers, hospitals and public housing sites added to map

Using the UDS Mapper, I was able to quickly and effectively visualize population health and resource data for a health center located within an Ending the Epidemic target county. If you’re interested in trying the UDS Mapper, go to, and don’t miss the Tutorials page for details on each of the tools I used and more. And finally, take advantage of National HIV Testing Day – attend a HRSA webinar, read up on the CDC website, get tested, or just spread the word using the #DoingItMyWay hashtag on social.

HealthLandscape and Men’s Health Week

Since 1994, the week leading up to Father’s Day has been officially recognized as Men’s Health Week. This advocacy campaign, hosted by Men's Health Network, promotes men’s health improvement measures during the entire month of June. During Men’s Health Week and throughout the month, men in the United States are encouraged to schedule appointments with their primary care physician (PCP), get more exercise, get screened for prostate health, eat healthy foods, and consider prevention as a way of life.

Outreach conducted by local and national groups focuses on disseminating statistics to bolster awareness related to men’s health. For example, according to Men’s Health Month, women are 100% more likely than men to seek out an annual visit to their PCP. Data from show that men live shorter lives, die at higher rates from the top 10 causes of death in the U.S., and are less likely to have health insurance. According to the Men’s Health Network, men are much more likely than women to die by homicide with some variation by race (1 in 30 for black males versus 1 in 132 for black females; 1 in 179 for white males versus 1 in 495 for white females). Equally alarming is the risk for suicide among men. In 2015, the CDC reported that men are four times more likely to commit suicide than women and that the rate of suicide among men 65 and over is 31.5% compared to 5% for women.

In honor of Men’s Health Week, HealthLandscape has added some exciting new county-level data related to men’s health to the Community HealthView data library. From the National Cancer Institute, we’ve added three datasets describing annual prostate cancer incidence, average prostate cancer cases per year, and prostate cancer incidence five-year trends from 2010 to 2014. From the U.S. Census American Community Survey, users can turn on a layer showing the percent of the population that are male for 2011-2015. Lastly, from the Centers for Disease Control and Prevention’s Diabetes Surveillance System, we’ve added measures on diabetes and obesity prevalence among men, as well as the percentage of physical inactivity among men. All three of these measures are from 2015, the most recent year for which data are available.

During Men’s Health Week and beyond, advocacy groups like the Men’s Health Network and local and state health departments can use tools like HealthLandscape’s Community HealthView to explore data on men’s health, identify geographic variation or overlap, and/or target resources to improve men’s health.

Family Health and Fitness Day and Park Exploration

Family Health and Fitness Day, created by the National Recreation and Park Association (NRPA), is celebrated annually on the second Saturday of June. Intended to show how important parks and recreation are to keeping their communities active and healthy, people are encouraged to visit their local parks to explore the recreational options available in their backyards. According to the Department of Health and Human Services, only one in three children are physically active every day and only one in three adults receive the recommended amount of physical activity each week. Parks can serve as local outlets for individual and community activities.

NRPA’s vision is that everyone has easy access to park and recreation opportunities in sustainable communities. To that end, they’ve partnered with the Trust for Public Land (TPL) in a nationwide movement called The 10-Minute Walk Campaign - ensuring that every person has a great park within a 10-minute walk. 

By visiting their site,, you can learn more about park access in your community. Seattle, for example, has a ParkScore ranking of 11. The TPL ParkScore rating is based on the following measures; access - the portion of residents within a 10-minute walk to a park, acreage - the median park size and percent of area dedicated to parks, community investment - park spending per resident, and available amenities - features like basketball hoops, playgrounds, and dog parks. 

In the interest of exploring issues of equity in access to parks and recreation, TPL takes their analysis even further by delving into park access by age, income, and race/ethnicity. All of these data points are available at the aggregate level, by city, and for each individual park.

Further, they use the data collected to make recommendations about where new parks might be best located, based on how many additional residents could be covered by the 10-minute walk radius, highlighting areas highest in need of funding and attention.

Clicking on an individual park polygon on the map will give you information about the service area within a 10-minute walk as well as a detailed report on the population being served by that location.

Want to quickly find the parks in your neighborhood? Check out the ParkServe webmap, created using TPL’s database of collected and user-added park locations, to find public parks near you. Click on any park location to find information about the name, owner, and address, where available.

Data Lovers Unite!

One thing the team at HealthLandscape believes in pretty consistently is the power of data visualization. We do it daily by building mapping and graphing tools, we teach it, we research it. We live it, we breathe it. That’s why it’s always great to go out to conferences and interact with our fellow data-philes (as you may have read earlier this week in our ACS Users Conference blog).

I try to live by the maxim don’t let the perfect get in the way of the good, particularly when it comes to health data. Health data are robust and fragile. They are comprehensive and limited. They are universal and unique. Since my role at HealthLandscape is primarily to teach people how to use our mapping tools, I try to gauge from an audience how much they care about the nuances and limitations of the datasets we use. Usually I get blank stares; after all, it’s not as fun listening to a list of datasets as it is to see a dynamic mapping tool in action and witness the power of those datasets.

This week, I represented the UDS Mapper at two conferences - the Northwest Regional Primary Care Association Spring Summit in Anchorage, Alaska, and the 2019 National Health Care for the Homeless Conference & Policy Symposium in Washington, DC. I had the opportunity to present in Anchorage and interact with attendees as an exhibitor in Washington. Aside from trying to sort out “when” I am after spanning so many time zones, I was surprised by how many people had deep questions about the data. Many people confessed to being closet data-philes and told me they want more. Their thirst for knowledge pushed me to really think about how these data could be used to answer their unique questions. They seemed to understand the data are not perfect and never will be, but are still useful and can help them continue to do the good work they are already engaged in.

Let the HealthLandscape team know about your data questions. Give us suggestions for new datasets we can add to our tools. Confess to us you are a data-phile. This is an inclusive, data-loving community and all are welcome!

P.S. I met one huge fan of the UDS Mapper this week, and I want to assure you all that if the future of public health data is up to her, we are in good hands.

2019 American Community Survey (ACS) Data Users Conference

The ACS Data Users Group is a partnership between the U.S. Bureau of the Census and the Population Reference Bureau, to promote the effective use and dissemination of ACS data, as well as educate users on data issues and best practices.

The annual ACS Data Users Conference, held May 14 and 15 this year, was a great opportunity to learn how others use ACS data, how the data can be used in concert with other federal and non-federal data sources, and how to keep up with the great data exploration and visualization tools people use (and develop) to get the maximum utility from this detailed demographic and economic data resource.

For me it was great to be introduced (actually, reintroduced) to the IPUMS data library at I hadn’t visited their collection for the better part of five or more years, and they have really expanded their offerings. By focusing on data curation and dissemination, and NOT analysis and visualization, they have been able to create wide ranging and still detailed collections of census (lower case c) and administrative survey records. It’s very much worth a visit to their site if you’ve never been (or like me, have been away too long).

Our Contribution at the 2019 ACS Data Users Conference

For my part, I was able to give two well-received presentations, including one that I delivered with Annu Jetty of the Robert Graham Center.
Zhang et al., Am J Epidemiol. 2014;179: 1025–1033 

Both papers focused on our use of an innovative modeling technique developed by researchers from the Centers for Disease Control and Prevention (CDC) to create small (sub-county) area estimates for specific health behaviors and health outcomes. These estimates are derived from sub-county ACS population measures 
(diagram shown above). In the first presentation, we showed how the Health Resources and Services Administration (HRSA) and the UDS Mapper enable you to do cold spot analysis to find high-need areas. My second presentation showed how our Population Health Profiler can help health care providers learn more about the health of the community (“Community Vital Signs”) that matches their actual patient-derived service area.
