Pocket Colposcope: Increased Distribution and Adoption (2016-2017)

Cervical cancer affects 500,000 women worldwide each year, resulting in more than 270,000 deaths annually. The majority of cases occur in low-income countries that cannot afford the tools commonly used in the United States. To address this challenge, researchers at Duke’s Global Women’s Health Technologies Center developed the Pocket (Point of Care Tampon) Colposcope to screen for cervical cancer. It has similar clinical performance to the existing standard of care colposcope, but has lower capital and maintenance costs ($250 compared to $20,000) and increased portability. They are seeking approvals to introduce the Pocket Colposcope into Peru and East Africa where they currently have regulatory approval but require market approval.

This Bass Connections project team used an innovative approach to identify the best strategy for adoption of the Pocket Colposcope in a country-specific setting. The global value chain analysis framework uses a holistic, system-based approach to map the ecosystem of activities and actors involved in a given development project.

Team members began by learning about the history, biology and prevalence of cervical cancer and various tools for diagnosing and treatment, and spent several weeks learning about the Pocket Colposcope device. They worked in teams to produce weekly reflection posts on the issues discussed, and used these as the basis of the front end of their final report. Manish Nair finalized his data analysis for a pilot study done in Summer 2016 and presented his findings at the Duke Global Health Institute’s Global Health Showcase.

To map the global value chain of the Pocket Colposcope, team members identified key stakeholders for interviews, drafted an interview guide and conducted field research in Peru in March 2017. These interviews were used to identify six leverage points where specific actions can help increase the likelihood of adoption of the Pocket Colposcope.

One leverage point is midwife training. Currently in Peru, colposcopy can only be performed by trained gynecologists. To increase access to cervical cancer screening, midwives can be trained to perform colposcopy with the Pocket Colposcope. Trainings should cover image capture, patient identification, telecommunication and disinfection. Another leverage point is telecommunication. Widely used in high-income countries, telemedicine leverages information and communication technologies to overcome geographical barriers and improve health. Because there are few trained medical professionals working in the Amazon forest, jungles, highlands and mountains of Peru, these areas are prime targets for telemedicine interventions.

Team members wrote a report, shared it with implementing partners, refined their recommendations and produced a final report that identifies the relevant actors, policies and leverage points for technology adoption.
