Feasibility Study of a Multimodal, Cloud-Based, Diabetic Retinal Screening Program in a Workplace Environment

Abstract

To evaluate the feasibility of capturing and interpreting retinal images in a workplace environment using a multimodal, cloud-based, diabetic retinal screening program combined with electronic self-reported questionnaires. The burden of diabetic retinopathy (DR) and other retinal conditions, healthcare utilization, and visual function were also assessed. Methods:A cross-sectional feasibility study was conducted at the Genentech, Inc., Campus Health Center. Eyes of participants were imaged using ultra-widefield (UWF) color fundus photography (CFP) and spectral-domain optical coherence tomography (SD-OCT). A cloud-based platform was used for the automated, seamless transfer of images to a remote reading center for evaluation for DR and other retinal pathologies. Electronic surveys collected participants'self-reported medical histories, healthcare utilization, and visual function data.Results: Among 100 participants (mean age, 43.9 years; 44% male), 33% of them selfreported diabetes. Eye examinations within the past 12 months were reported by 71% of all participants (n = 71/100) and by 85% (n = 28/33) of those with self-reported diabetes. Among participants with complete screening images from both UWF-CFP and SD-OCT, 20% (n = 6/30) of those with self-reported diabetes and 8.5% (n = 5/59) of participants with no history of diabetes were unaware they had mild/moderate nonproliferative DR. Among all participants, 20% (20/100) had a retinal finding, on either UWF-CFP or SD-OCT, or both, which prompted a referral for further evaluation. Conclusions:A retinal screening program deployed via a secure, scalable, and interoperable cloud-based platform was feasible and conveniently integrated into the workplace.Translational Relevance: Cloud-based platforms could be used to promote a secure, scalable, and interoperable system for retinal screening in nontraditional environments.

A Study of Cloud-Based Remote Clinical Care Technology

“…The establishment of a cloud computing platform also helps medical diagnosis, such as for lung nodules, by storing huge amounts of relevant medical data in the cloud platform, so that clinicians can quickly and accurately make a diagnosis by comparing and referring to existing databases through cloud computing. It is considered that the core content of smart medical includes the intelligent perception of medical objects, standardized disposition of medical processes, and integration of medical objects and medical processes through interconnection technology, and based on intelligent management of people, objects, and equipment, the medical IoT application model is studied from the medical service application model, medicine management application model, and medical device management application model, and the internal hospital medical [ 13 ]. The process of the digital collection, processing, storage, transmission, and sharing of medical information, equipment information, drug information, personnel information, and management information within the hospital is designed.…”

The Optimization of Hospital Financial Management Based on Cloud Technology and Wireless Network Technology in the Context of Artificial Intelligence

“…People's usage of technology is influenced by a variety of circumstances, including how they communicate with one another and where they live and work. Digital administration in operating rooms is becoming increasingly vital in the process of creating a digital hospital, and it is becoming more prevalent [13] [14].…”
