Crossing disciplines and using technology could help populations in need

Medical researchers must work together across disciplines to provide better health care to those who need it most, according to panelists at Stanford Medicine’s Annual Population Health Sciences Colloquium.

The symposium, hosted by the Stanford Center for Population Health Sciences, brought together working groups from across the Stanford campus to showcase the latest findings in population health research.

“Population health science at Stanford is likely to make the most important contributions when we cross traditional intellectual expertise disciplines,” said Paul H. Wise, a core faculty member at the Center for Health Policy/Center for Primary Care and Outcomes Research (CHP/PCOR).

Many of the scholars at the daylong conference on Tuesday stressed that an interdisciplinary approach to health care is crucial to understanding and aiding underserved populations.

“To deal with life-course questions we need to create-life course observational windows,” said Mark Cullen, chief of the Division of General Medical Disciplines and director of the Stanford Center for Population Health Sciences.

Instead of trying to create an all-encompassing care plan for the human population as a whole, panelists demonstrated that studying the needs of particular groups, or smaller populations, can better serve individuals within populations that may not receive the best care.

Douglas K. Owens, director of CHP/PCOR, said the U.S.  Preventive Services Task Force, of which he is a member, has “often faced a real paucity of data trying to develop prediction guidelines for both the very young and the old.”

The Task Force, a panel of experts that makes recommendations for medical prevention services, is generally able to make guidelines for large populations like adults, but suggestions for specialized groups like children and the elderly are more challenging. Though Stanford researchers like Wise are working to improve care for particular sectors like children, more study is needed.

Several speakers at the conference said the underserved population of poor children could benefit from research targeted toward their population group.

“We don’t really understand the biology of the life-course, why things taking place in gestation and early life actually affect healthy aging and adult onset disease,” said Wise, adding, “We have a very poor understanding of how to translate this understanding into effective interventions for communities in need.”

Panelists agreed that big data can help them understand smaller, poorly served populations, such as young children in impoverished communities. By collecting large amounts of data from the general population, researchers will increase the amount of data available for more specific groups. This allows researchers to study these populations more closely and help create better outcomes.

Abby King, a professor of health research and policy and of medicine, and Jason Wang, director of the Center for Policy, Outcomes and Prevention (CPOP) and a CHP/PCOR core faculty member, believe life-course digital applications can provide individualized care while collecting data on a large-scale.

According to King, a life-course app, or a device to track health and provide care throughout one’s life, would grow with the user and help them through important developmental stages.

Wang has taken a first step toward creating such an app with PLAQUEMONSTER.  Intended for children eager for Halloween candy, the PLAQUEMONSTER app provides kids with a “tooth pet” they must keep safe from “plaquemonsters” and the so-called evil candy corporation. By flossing and brushing their teeth each day, kids earn points, and Wang’s team hopes the game will encourage good dental hygiene.

Health-care techniques using mobile devices, known as mHealth, could be particularly useful in underserved populations. King notes that even low-income populations have cell phones, so using phones as health-care tools could help decrease the gap between higher- and lower-income populations.

“I think for us one of the major challenges of the century is to really close that health-disparities gap and mHealth can help.”

However, each app must be tailored to the user.

“There’s no reason to believe that an African-American 16-year-old is going to be motivated the same way as a 45-year-old white man,” said Wang. “You need to involve patients in the design of the app.” When the app fits the specific patient’s needs, they are more likely to use it regularly, and knowing the needs of their population helps determine their preferences.

As the world continues to become more connected, the panelists said that reaching across disciplines and incorporating technology may hold the key to effective health care in the 21st century.
