From Duke’s Labs to Patients in Peru: Students Work to Deploy New Cervical Cancer Screening Tool

Students in the Bass Connections: Pocket Colposcope team traveled to Peru to research how to deploy a new medical device into an existing healthcare system

By the time spring break rolls around, students are typically antsy to leave campus for a different destination, whether that means relaxing at home or adventuring in a far-away country. Although an exotic location was certainly in the books for some students in Duke’s Bass Connections—Pocket Colposcope: Increased distribution and adoption program, their activities weren’t part of the usual spring break fare. Instead, the team traveled to Lima, Peru to continue their ongoing study of how an innovative cancer screening tool could best be deployed within the country’s healthcare system.  

The Pocket Colposcope was developed by Duke’s Center for Global Women’s Health Technologies as a tool to help doctors screen for cervical cancer in low- and middle-income countries, where, according to the World Health Organization, more than 85 percent of the annual deaths from cervical cancer occur. To address the barriers associated with screening, the Pocket colposcope was designed to be significantly less expensive and more portable than a standard colposcope, and the device has the potential to increase cervical cancer awareness and screening, saving lives in the process. But first, it must be successfully adopted in the local environment.

To pave the way toward this goal, the students conducted in-depth interviews with clinicians, public health officials, industry partners and researchers about their work and their thoughts on the Pocket Colposcope—fitting weeks of work into five business days.

The spring break trip to Peru is part of a yearlong Bass Connections team led by Nimmi Ramanujam of BME and Rae Jean Proeschold-Bell of the Duke Global Health Institute, and taught by Krieger and Danny Hamrick, a research analyst with the Duke University Center on Globalization, Governance and Competitiveness.  With a diverse team of undergraduate and graduate students from biomedical engineering, global health, psychology, business and beyond, the program uses as its framework a development approach known as global value chain analysis—a holistic, systematic approach to mapping out the planned use of a new tool to identify potential bottlenecks and challenges to deployment.

“This program allows for different viewpoints to come together to address a problem, and everything is centered around a real-life issue—in this case, cervical cancer,” says Hamrick. “We really get to see how people from various disciplines approach different strategies to get this tool into the field.”

On the first working day of the trip, the students visited the Ministerio de Salud del Peru (Peruvian Ministry of Health), where they discussed how the public health system had focused its efforts on combatting cancer to date. From there, the students split up into two teams to cover more ground. Some, like Avni Mehta, a sophomore in BME, toured area hospitals and clinics to determine how the Pocket Colposcope could serve both affluent and resource-limited hospitals. This leg of the tour also involved a stop at mobile health clinics, which currently offer Pap smears to women outside of Lima and could potentially expand to colposcopies with the new portable tool.

“To me, it was great to see that a lot of people seemed to know about the importance of these cancer screening services, and the mobile vans were popular where people were even calling their friends to come over and get screened,” says Mehta. “Visiting these places really showed us how our research could have a palpable impact on people’s lives.”

Although the students were interested in studying the immediate impact the tool could have in hospitals and clinics in the area, they also visited the League Against Cancer (La Liga Contra el Cancer) and the biomedical engineering department at the Pontifical Catholic University of Peru. At each institution, students were given a broader overview about how Peru’s public health system was promoting cancer screening, and they saw how the university’s BME department conducted its own cancer research.

 A highlight for several students was meeting with caregivers who were developing new ways to bring medical services to people around the city using a smartphone app. This tool for ‘mobile medicine’ gave the students a new avenue to pursue with the Pocket Colposcope, says Manish Nair, a BME senior  in the Bass Connections project.Students visit PUCP in Lima, Peru

“I think that was exciting for all of us because we could see the way our tool could fit into their current system in terms of portability and ease of use,” says Nair. “It was inspiring to hear and see that people are using technology in such new and innovative ways in Lima.”

The trip’s primary purpose was to allow students to gather research for the team’s global value chain analysis, but they also used the opportunity to familiarize themselves with a world that was different from their lives at Duke. During their stay in Lima, students visited the ruins of Machu Picchu, sampled the local cuisine, and learned how to navigate the sprawling city. To reflect on these experiences—and their research—the students updated blogs detailing their time abroad.

Now back at Duke, the Bass Connections team is analyzing their findings to determine what challenges they still face, what the bottlenecks are in the health care market in Lima, and steps they need to take going forward. They will present these findings during a Bass Connections showcase on April 20. And, the work will continue with the 2017-2018 Bass Connections team, where students will work to train health care providers how to use the Pocket Colposcope.

But for now, the team is pleased with a successful trip.

“Nothing beats the experience of actually being out in the field with your teammates, and after the trip we are much closer and understand each other at a different level,” says Nair. “Now we truly understand how to work together to solve any problems that pop up.”
