Implementing Technology That Disrupts Health Systems but not Quality of Care: The Pocket Colposcope in Lima, Peru

[摘要] PURPOSE Innovative devices are often targeted at increasing access, improving quality, or reducing costs—the three axes of the infamous Iron Triangle of Health Care, which are notoriously difficult to simultaneously optimize. The main aim of this study was to demonstrate that disruptive technologies, if high quality and appropriately implemented, can result in improved access, cost, and quality of care, overcoming the conventional constraints of the Iron Triangle framework. METHODS Our team conducted a global value chain analysis of the Pocket Colposcope in Lima, Peru, and developed surveys and conducted in-depth interviews to evaluate Pocket Colposcope stakeholders. All surveys were developed with consultations from the Duke Evidence Lab and had institutional review board approval. RESULTS The global value chain identified 5 leverage points: regulatory approval, task shifting, collaboration, telemedicine, and patient acceptance. We also identified stakeholders and processes that affect the degree to which the Pocket Colposcope is successfully implemented. Of women surveyed, 39.4% answered that they had previously wanted a cervical cancer screening test, but had been unable to receive one as a result of some barrier. The most common responses were distance to clinics (31.0%), participants could not leave work (27.6%), and patients were afraid of receiving a cancer diagnosis (20.7%). All 4 midwives who participated in the focus group identified the portability of the Pocket Colposcope as the device’s most appealing feature. Providers identified the quality of the image, cost to patient, and ease of use as the 3 most important aspects of the Pocket Colposcope. CONCLUSION The Pocket Colposcope provides an opportunity to make high-quality diagnostic technology more accessible at a cheaper price for more people. Often, disruptive technology in low-income settings is expected to increase access at the cost of reducing quality. In the case of the Pocket Colposcope, the disruptive technology is significantly cheaper than existing technology, but quality is still high enough to succeed.
