Health and Medicine

FSI’s researchers assess health and medicine through the lenses of economics, nutrition and politics. They’re studying and influencing public health policies of local and national governments and the roles that corporations and nongovernmental organizations play in providing health care around the world. Scholars look at how governance affects citizens’ health, how children’s health care access affects the aging process and how to improve children’s health in Guatemala and rural China. They want to know what it will take for people to cook more safely and breathe more easily in developing countries.

FSI professors investigate how lifestyles affect health. What good does gardening do for older Americans? What are the benefits of eating organic food or growing genetically modified rice in China? They study cost-effectiveness by examining programs like those aimed at preventing the spread of tuberculosis in Russian prisons. Policies that impact obesity and undernutrition are examined; as are the public health implications of limiting salt in processed foods and the role of smoking among men who work in Chinese factories. FSI health research looks at sweeping domestic policies like the Affordable Care Act and the role of foreign aid in affecting the price of HIV drugs in Africa.

Wei Huang uses the experience of China's One Child Policy to examine how fertility restrictions affect economic and social outcomes over the lifetime. The One Child Policy imposed a birth quota and heavy penalties for “out-of-plan” births. Using variation in the fertility penalties across provinces over time, He examines how fertility restrictions imposed early in the lives of individuals affected their educational attainment, marriage and fertility decisions, and later life economic outcomes. Exposure to stricter fertility restrictions when young leads to higher education, more white-collar jobs, delayed marriage, and lower fertility. Further consequences include higher household income, consumption, and saving. Finally, exposure to stricter fertility restrictions in early life increases female empowerment as measured by an increase in the fraction of households headed by women, female-oriented consumption and gender-equal opinions. Overall, fertility restrictions imposed when agents are young have powerful effects throughout the life cycle.

Vast amounts of molecular data characterizing the genome, epi-genome and transcriptome are becoming available for a wide range of cancers. In addition, new computational tools for quantitatively analyzing medical and pathological images are creating new types of phenotypic data.  Now we have the opportunity to integrate the data at molecular, cellular and tissue scale to create a more comprehensive view of key biological processes underlying cancer. This integration can have profound contributions toward predicting diagnosis and treatment. Prof. Gevaert will discuss current work in progress to tackle challenges in biomedical multi-scale data fusion. Olivier Gevaert is an assistant professor at Stanford University focusing on developing machine-learning methods for biomedical decision support from multi-scale biomedical data.

Liat Clark from Wired writes about REAP's vision care social enterprise, Smart Focus Vision, winning the Clearly Vision Prize for startups that bring low-cost vision care to rural communities around the world. Read the original article here.

Smart Focus Vision

Stanford, CA

The US-based startup has partnered with eyewear company Luxottica OneSight to help scale eye care to ten million people in China that do not have access to affordable services. According to research conducted by Stanford University, only one out of six rural children in China has a set of glasses and most rural students have never had an eye exam. The for-profit ran a pilot operation in conjunction with the Chinese Academy of Sciences before launching in the provinces of Shaanxi and Gansu, where it distributes low-cost glasses, trains doctors and teachers, and constructs clinics. Teachers can test vision directly in classrooms and use mobile phones to automate patient referrals and prescriptions. Smart Focus argues the nonprofit route would never have been a sustainable or scalable way of helping the number of children that need eye care.

As well as a share of the prize money, the winners will have access to mentoring and be invited to a series of one-day events - Clearly Labs - around the globe where they can meet optometrists and other entrepreneurs. The campaign has a number of high-profile advisers onboard, including cofounder of Warby Parker, Neil Blumenthal and founder of Shanghai Tang, David Tang, who commented: "Access to good sight should not be a luxury. Yet, 2.5 billion people are still forced to go without clear vision. Radical new thinking is necessary to rectify this.”

Paragraphs

In the June 2016 publication of the EYElliance and World Economic Forum report, "Eyeglasses for Global Development: Bridging the Visual Divide," a case study for REAP's Smart Focus social enterprise was published on page 21. Read the entire report here.

The Rural Education Action Program (REAP), an impact-evaluation organization, aims to inform sound education, health and nutrition policy in China. Since 2011, REAP’s five randomized controlled trials have shown that quality vision care is the most cost-effective intervention for improving child welfare, and leads to large and sustainable increases in learning and school performance, along with positive spillovers to children who don’t have poor vision.

REAP is now establishing a network of for-profit vision centres based at county hospitals through an initiative called Smart Focus. Those centres partner with schools to deliver high-quality vision care. Optometrists administer six hours of training for classroom teachers, enabling the latter to conduct initial vision screenings and refer students needing more advanced care through a highly structured referral system. The teachers are provided free mobile-phone time as an incentive, and the vision centres earn revenue from urban consumers in a cross-subsidization scheme that supports providing care for poorer rural consumers whose unmet need is greatest. To date, REAP has provided access to free or affordable glasses for over 30,000 primary school students and screened an additional 120,000 children.

In addition to screening children and supervising their wearing glasses, teachers play a vital role in communicating with parents. Once a teacher’s screening indicates a child needs glasses, the teacher often spends significant time convincing parents that (a) the child’s condition requires attention, (b) the problem is correctable, and (c) taking the child to the vision centre to get glasses is highly advisable. 

Vision centres dispense “first pair free” or very low-cost glasses to rural elementary- and middle-school students, while providing part of the urban market with refraction and eyewear on a fee-for-service basis. Giving away the first pair of glasses is not “just charity”; rather, it provides access to the huge untapped rural market. To build confidence, vision centres unconditionally guarantee the frames for three months and lenses for six months, something that no private optician does. (A noteworthy challenge arises, however, with parents who believe that low-cost or free services must also be of low quality; usage rates and eyeglass prices have been shown to rise in tandem.)

Smart Focus provides county hospitals with management, retail expertise, training and equipment. Critically, the programme assigns a Smart Focus staff member at 
each vision centre to coordinate construction and staff training, and to manage operations and logistics, including relationship-building with schools, hospitals and optical suppliers. To date, REAP has built four vision centres with full approval from the county education and health bureaus. As revenues rise, Smart Focus is committed to expanding the network of vision centres to new counties that lack appropriate care. 
 
In addition, and in collaboration with Zhongshan Ophthalmic Center, Smart Focus arranges training in optometry and vision-centre management for three staff members from each centre. Smart Focus also trains nurses as optometrists through classroom instruction and an in-the-field training and mentoring programme. By the end of their training, nurses are certified to refract patients and make glasses, as well as identify more complex but common eye disorders for referral to ophthalmology departments. Further, Smart Focus pays vision centre staff salaries for the first six months during training and mentoring, and facilitates the centres’ purchasing of frames and lenses. Across China, 2,000 county hospitals each serve 400,000 people annually.
