Exploring the Feasibility of Opportunistic Diabetic Retinopathy Screening with Handheld Fundus Cameras in Primary Care: Insights from Doctors and Nurses

Aims: This study aims to assess the perspective of doctors and nurses regarding the clinical settings and barriers to implementing opportunistic diabetic retinopathy screening with handheld fundus cameras. Design: This study was a cross-sectional, online questionnaire study. Methods: An online survey was distributed to doctors and nurses working in Portuguese primary care units and hospitals between October and November 2021. The survey assessed current fundus observation practices, potential contexts, and barriers to using handheld fundus cameras. Results: We received 299 eligible responses. About 87% of respondents (n = 255) believe in the clinical utility of handheld fundus cameras to increase patients’ access to diabetes-related retinopathy screening, and 74% (n = 218) attribute utility to identify other eye or systemic diseases. More than a third of participants (37%, n = 111) envisioned using such devices multiple times per week. The main potential barriers identified included limited time (n = 90), equipment cost (n = 48), or the lack of skills in retinal image acquisition (n = 47). Most respondents (94%, n = 275) expected a follow-up recommendation to accompany the telemedicine diagnosis. Conclusions: Doctors and nurses support the use of handheld fundus cameras. However, to optimize their implementation, some strategies should be considered, including training, telemedicine-based diagnosis, and support for follow-up through accessible, user-friendly, and efficient information systems.
