Looking at Health Departments’ Ever-Changing Future: A Discussion of the Recent Findings of the Public Health 2030 Project


From the dramatic impact of extreme weather events such as Hurricanes Katrina and Sandy, to the rapidly changing policy landscape of health care providers, the functions, missions and futures of public health agencies continue to change.

To help health departments plan for an uncertain future, the Institute for Alternative Futures—with support from the Robert Wood Johnson Foundation and the Kresge Foundation—recently worked with state and local health departments, leaders and experts in the field to look forward to the year 2030 and analyze public health scenarios in order to offer pathways to expectable, challenging and visionary futures for public health.

On Tuesday afternoon at APHA, Clement Bezold, PhD, the Founder and Chairman of the Institute for Alternative Futures, and Terry Allan MPH, will discuss theses scenarios and findings and insights gained.

Prior to their presentation, NewPublicHealth sat down with Bezold for an exclusive preview of his presentation.

NewPublicHealth: How did your APHA presentation come about?

Clement Bezold: The presentation is based on the Public Health 2030 project, and that project came about following scenario reports on primary care, on vulnerability, social and economic vulnerability in the United States and on health and health care.

NPH: What are some of the key points about the Public Health 2030 project?

CB: With Public Health 2030, there are a host of challenges and opportunities facing health departments. There are the ongoing fiscal issues at the state and local governmental levels, there’s increased infectious disease, there are climate-change-related changes that communities are facing.

Faces of Public Health: Julio Frenk, Harvard School of Public Health


Several weeks ago, the Harvard School of Public Health celebrated its Centennial with fanfare, fundraising and a panel discussion featuring world health leaders who are graduates of the school. Following the centennial, NewPublicHealth spoke with the School’s Dean, Julio Frenk, MD, MPH, PHD, who has a joint appointment at the Harvard Kennedy School of Government. He is also a former health minister of Mexico and a former senior fellow in the global health program of the Bill and Melinda Gates Foundation.

NewPublicHealth: What do you think have been the key changes in public health efforts since the Harvard School of Public Health was founded 100 years ago?

Julio Frenk: The 100 years that have passed since the School of Public Health was founded are not just any 100 years—they’re the 100 years with the most intense transformations in health in human history. We have seen a more than doubling of life expectancy since the school was founded. Around 1900, the global average for life expectancy was 30 years. At the end of the century, the global average was about 65 years. It more than doubled in the 20th century, and that increase has continued with some setbacks, most notably the AIDS epidemic in Saharan Africa. And we have had a qualitative shift not just in the level of mortality, but in the causes of death. So we went from a preponderance of acute infections to now a predominance of mostly chronic non-communicable diseases, and that’s an incredible transition.

A critical change is that the experience of illness became very different starting from the beginning of the 20th century. Before then, illness was mostly a succession of acute episodes, from which one either recovered or died. If you recovered, you went on to get your next acute illness. Now, illness is more a condition of living. People live with cancer. People live with AIDS. So that’s a big transformation of the patterns of health, disease and death.

Another big change is the emergence of complex health systems, and that’s—again—a process that started at the beginning of the 20th century. Before the 20th century, the social function of the sick was mostly trusted to undifferentiated institutions, such as the family or religious institutions, and it’s not until the 20th century when you see this incredible explosion of specialized institutions and specialized human resources, doctors, nurses and other health professionals. In the 20th century, healthcare is 10 percent of the global economy and employs millions of people, including eight million doctors. These are all profound transformations.

NPH: How has the training of students of public health changed in the last 100 years?

Frenk: There has been profound change. What happened at the beginning of the 20th century was the emergence of public health as a field of action. The practices of engineering emerged in Europe, especially with the rapid urbanization there starting around the 17th century, but then greatly expanded in the 18th century. Engineering allowed for access to clean water and taking care of waste, which resulted in some diseases coming under control. In the 19th century the discovery of microbiology gave rise to the abolishment of the germs as causes of illness. That is the junction that gives birth to public health, along with the idea of social policy, of social activism that actually changed social conditions. It’s in that mix that public health gets shaped.

The Association of Schools and Programs of Public Health (ASPPH), like the American Public Health Association, held its annual meeting in Boston last week. NewPublicHealth spoke with Harrison Spencer, MD, MPH, executive director of the ASPPH, from Boston about the meeting and what’s ahead for students of public health.

NewPublicHealth: How was the meeting and what were some of the key sessions?

Harrison Spencer: Our meeting this year was the first one held since we formed our new organization, the Association of Schools and Programs of Public Health, on August 1. The new organization is now comprised of all accredited public health academic institutions, both schools and programs. We’ve got 93 members now, an increase from 57 members before, so this was a wonderful and exciting and dynamic annual meeting with lots of energy and lots of promise.

Among the highlights were Harvey Fineberg, MD, PhD, president of the Institute of Medicine, who gave us an inspirational talk about public health leadership, and Laura Liswood, Secretary General of the Council of Women World Leaders, who led a discussion on diversity as a way to make organizations and institutes stronger.

In a Government Shutdown, Who’s Tracking the Flu?

Add flu surveillance to the list of casualties of the current government shutdown.

Every flu season, states collect data on flu cases — including case reports and viral specimens — and send those to the Centers for Disease Control and Prevention (CDC) in Atlanta for recording and tracking. That tracking is critical in order to:

  • provide information on how well-matched the seasonal flu vaccine is to the flu viruses found in the community;
  • identify severe outbreaks that require increased supplies of antiviral medicines for people who contract the flu; and
  • identify emerging strains that might require a new vaccine to be developed this season, which is what happened several years ago when CDC identified the H1N1 influenza virus toward the end of the flu season, and quickly ramped up for a new vaccine.

Flu season generally runs October through April, with the peak from about January to March. If the shutdown continues then, “as the flu season goes on, our knowledge of what’s happening will be impaired,” says William Schaffner, MD, Professor of Preventive Medicine and Infectious Diseases, Vanderbilt University School of Medicine, and the immediate past president of the National Foundation for Infectious Diseases.

CDC director Thomas Frieden, MD, MPH, underscored his concern in a tweet on the first day of the government shutdown: “CDC had to furlough 8,754 people. They protected you yesterday, can't tomorrow. Microbes/other threats didn't shut down. We are less safe.”

Keeneland Q&A: Joe Selby

Joe Selby, MD, MPH, head of the Patient-Centered Outcomes Research Institute Joe Selby, head of PCORI

A constant theme of this year’s Keeneland Conference is the emergence of the discipline of public health systems and services research (PHSSR) from strict research and evaluation to results that are beginning to be used by public health departments and agencies. So who better a dinner speaker than Joe Selby, MD, MPH, head of the Patient-Centered Outcomes Research Institute (PCORI), authorized by Congress under the Affordable Care Act. PCORI’s role is to conduct research and provide information about the best available evidence to help patients and health care providers make more informed decisions. The Institute's goals include:

  • Substantially increase the quantity, quality, and timeliness of useful, trustworthy information available to support health decisions.
  • Speed the implementation of patient-centered knowledge into practice.
  • Influence clinical and health care research funded by others to be more patient-centered.

NewPublicHealth spoke with Dr. Selby about PCORI’s work so far and the critical goal of disseminating scientific research to improve health.

NewPublicHealth: Tell us about your talk at the Keeneland Conference.  

Dr. Selby: I’ll start by talking about the historical trends that led to PCORI’s formation. I think that these trends are bringing what we do, which is called comparative clinical effectiveness research, together with quality improvement and with public health systems and services research. There is a convergence of interests between what the conference attendees do as public health practitioners and public health researchers and systems-based researchers and what the quality improvement world is doing and what we’re trying to do at PCORI. There are many common bonds and a new appreciation for that.

It has suddenly dawned on everyone that you’ve got to put your patients or, in the case of public health, your communities, at the center of the research activity. And I know that in the public health world, they are involving communities and patients within communities and clients and consumers in their planning and intervention activities. That is one of the bonds that ties us together and that leads to enhanced productivity whether we’re doing clinical research like PCORI does, whether we’re doing quality improvement, or whether we’re doing public health.

Public Health and Big Data: What are the Implications for the Field?

"Information is the oil of the 21st century, and analytics is the combustion engine.” - Peter Sondergaard

That was a quote from panel at APHA 2012 on how new data mapping tools can help support health departments and vulnerable population. Taking a look at everything from local health department budget cuts and their effect on vulnerable populations to how “big data” has implications for public health trends, the panel made an effective argument for the fact that mining data sets has increasingly important ramifications for the public health field and practitioners.

“We’re gonna get technical,” warned Matthew Dollacker of CSC, during his presentation. “But we can come away with a real appreciation for a fundamental shift that is taking place through what big data technology can do.”

>>Read related thought leader conversations on harnessing the power of Big Data:

  • Read a conversation with Farzad Mostashari, National Coordinator for Health Information Technology at the U.S. Department of Health and Human Services.
  • Read a Q&A with Thomas Goetz, Executive Editor of WIRED Magazine.
  • Watch a video interview with Reed Tuckson, Executive Vice President of UnitedHealth Group.

Dollacker pointed out that today, we’re in a new era of data. Users posts about 2,200 tweets per second to Twitter, and conduct 1.6 billion searches today. Originally, decoding the human genomte took 10 years to process – today, it can be achieved in one week.

Using Data Well: NewPublicHealth Q&A with John Lumpkin

file John Lumpkin, senior vice president and director of the Health Care Group at Robert Wood Johnson Foundation

At the Health Data Initiative III: The Health Datapalooza this summer, which looked at the role health data plays in transforming health and health care, the Robert Wood Johnson Foundation (RWJF) announced the three winners of an app challenge calling for developers to create applications that would allow consumers to easily access and make use of comparative information about the quality of care provided in various regions of the country. The data behind the apps came from Aligning Forces for Quality, the Foundation’s initiative to improve the quality of health care in 16 targeted communities.

John Lumpkin, MD, MPH, senior vice president and director of the Health Care Group at RWJF, presented the awards to the top three winners of the challenge. Recently, NewPublicHealth spoke with Dr. Lumpkin about the explosion of health care data, and how to find the strongest data and use it well.

NewPublicHealth:  Quantities of health data are increasing at a speedy clip. What kind of challenge does that pose in order to make sense of the numbers?

Dr. Lumpkin: In a single day there are over 300 million photos that are being posted on Facebook, and 3.2 billion likes and comments. We have 115,000 people participating in web sites such as Patients Like Me and about 9 million tweets each day. So we have all this data, but how do we access it in ways that make it meaningful? Kerr White, MD, the chairman for the U.S. National Committee on Vital and Health Statistics once said: “With the advent of new technology, data can be collected in any format, aggregated by the computer and arrayed in any desired output…untouched by human thought.” And so our challenge is to present it in a way that we actually have it touched by human thought.

Some good examples of this would include the County Health Rankings and the Aligning Forces for Quality Initiative where we have coalitions of consumers, purchasers and providers who, through public reporting of quality and price information and consumer engagement, we encourage to adopt quality improvement methods and use the data in ways that move that process forward.

NPH: Does everyone mean the same thing when they talk about “evidence-based” data?
