Pocket Colposcope: Increased Distribution and Adoption (2017-2018)

Cervical cancer affects the lives of 500,000 women worldwide each year, resulting in more than 270,000 deaths annually. Because the majority of cases occur in low-income countries that cannot afford the tools commonly used in the United States, new solutions must be found.

To address this challenge, researchers at Duke’s Global Women’s Health Technologies Center have developed a Pocket (Point-of-Care Tampon) Colposcope to screen for cervical cancer in low-resource settings.

In 2016-2017, the team conducted a global value chain analysis where the identification of specific actions can help increase the likelihood of adoption of the Pocket Colposcope in Peru. The 2017-2018 team focused on the activities involved in launching a community health provider program to implement Pocket colposcopy at the primary care setting.

The team evaluated the best practices for creating a training program for community-level providers and developed a comprehensive and culturally appropriate training manual to be iterated on based on feedback from community health providers working with La Liga Contra el Cancer. The team also conducted preliminary field testing of their training protocols in Lima, Peru, and assessed the impact of the training model on the Peruvian community health providers.

The team produced a training toolkit for Pocket implementation; a promotional video for patient advocacy an awareness in the Peruvian context; a physical platform prototype for demonstrating the Pocket Colposcope; a cost-effective analysis of the device in Peru; and a qualitative stakeholder assessment.
