When students enter the UCLA Fielding School of Public Health for their MPH education, they choose one of five academic departments: Biostatistics, Community Health Sciences, Environmental Health Sciences, Epidemiology, and Health Policy and Management. But the multidisciplinary nature of public health demands that no matter what the area of focus, the successful professional be well versed in all five.
“When our MPH graduates get public health jobs, they don’t work in silos,” says Dr. Yifang Zhu, professor of environmental health sciences and senior associate dean for academic programs at the UCLA Fielding School. “They collaborate with colleagues and need to be able to speak the language of people in other public health disciplines, and appreciate the perspectives public health professionals in those disciplines bring to the table.”
The school’s desire to present first-year MPH students with an introduction to the foundations of public health from an integrated perspective — in which faculty representatives from each of the five departments teach on the same public health issues and students from each department work together to address them — provided the impetus for PH 200A and 200B, a course now taken by all MPH students in their first two quarters at FSPH. Designed by an interdepartmental faculty team, the curriculum is delivered through a mix of traditional lectures and active-learning, case-based classroom discussions and presentations.
Before the integrated core curriculum, which was first offered to students in the 2019-20 academic year, students took separate introductory courses from each department, with limited opportunity for interactions with students in other departments. “Previously, we received feedback from students and alumni that they would appreciate more opportunities to interact with students outside of their home department,” Zhu notes. “This course allows them to experience a wider range of perspectives, and to see how those perspectives come together in real-world public health scenarios."
“Our students are going to work in multidisciplinary teams in their careers, and so it’s very helpful to have them doing that from the beginning of their public health education,” says Dr. Karin Michels, professor and chair of FSPH’s Department of Epidemiology, who co-chaired the PH 200 series with Zhu in 2020-21. “And by working on a specific problem with students who have chosen other concentrations, they learn to appreciate other disciplines within public health.”
Michels estimates that about half of schools of public health use an integrated model to teach the foundations of the profession, but what differentiates the UCLA Fielding School’s approach from many others is the emphasis on case-based teaching. Each quarter, three case studies are introduced — for 2020-21, topics involved the trans-fat campaign in New York City, the Affordable Care Act, e-cigarettes, arsenic mitigation in Bangladesh, COVID-19, and climate change. For each case, one of the course’s five instructors serves as the lead and presents the background, and then each of the other instructors teaches on the salient issues from their vantage point.
As an example, for COVID-19, students learned from the biostatistics perspective about the design of vaccine trials and how to interpret the results, such as what it means to be 95% effective. They took in key epidemiological concepts used to monitor progress against the pandemic. From the community health sciences side, they explored the social determinants involved in which communities are most disadvantaged. They learned about the role of the environment in the transmission of the disease, and the importance of variables such as air pollution and masks. And from the health policy and management angle, they learned about considerations involved in the healthcare response, and in establishing policies for COVID-19 testing and vaccine prioritization. For the 2020-21 series, every case was taught through the lens of systemic racism.
“We’re framing the materials in a story,” Michels says. “For example, instead of explaining how you design a case-control study and what biases you look for, we first describe the problem and then discuss the types of studies you might design to resolve the problem, which allows the students to learn by doing.”
