Pocket Colposcope: Analysis of Bringing Elements of Referral Services to Primary/Community Care (2018-2019)

Invasive cervical cancer affects 500,000 women worldwide each year. Unlike most cancers, it is highly preventable through the screening, diagnosis and treatment of cervical precursor lesions.

Colposcopy with biopsy is the gold standard for diagnosis of precancerous lesions. However, colposcopes are expensive, and require referral to a facility that can house this machine as well as a trained colposcopist who can interpret the images. These factors make colposcopy inaccessible to the many women in low- and middle-income countries who are at greatest risk for developing cervical cancer.

To address this limitation, Duke researchers have developed a device called the Pocket Colposcope. It is more than an order of magnitude less expensive and lighter than commercial colposcopes. The first year of this Bass Connections project in 2016-17 was dedicated to performing a global value chain analysis in order to identify leverage points that can increase the likelihood of adoption of the Pocket Colposcope in Peru. In 2017-18, team members focused on launching a community health provider program to implement the Pocket Colposcope at the primary care setting in Peru. The 2018-2019 team focused on the clinical acceptability, economics and policy of the Pocket Colposcope to demonstrate the device’s economic viability in the community health setting.

Team members researching clinical acceptability created three surveys to assess patient and provider views on the use of the device. The surveys were sent to patients not currently using the device, providers not currently using the device and patients enrolled in a clinical trial for the device. Findings from the surveys helped the team conclude that working with reimbursement systems and insurance companies is essential to ensuring provider acceptability. For patients, the team learned that they need to further study the procedures and providers that patients trust.

Team members working on the economics of the device researched which markets were best for their product. The team found that the colposcope was most desired by OB/GYNs replacing equipment or wanting to expand their practices to rural areas. Additionally, family practice practitioners who wanted to expand the scope of their practices were also interested in the device. The team projects that over 9,000 devices will be sold annually, with demand increasing each year.

In terms of policy, the team addressed ethical concerns around the feasibility of performing biopsies. They convened legal, medical ethics and stakeholder panels to discuss how to investigate potential issues and ways to properly regulate the colposcope. Moving forward the team plans to determine policy needs for implementing use of the device into North Carolina.
