Ten Years of Experience With a Telemedicine Platform Dedicated to Health Care Personnel: Implementation Report

BACKGROUND

Telemedicine, a term that encompasses several applications and tasks, generally involves the remote management and treatment of patients by physicians. It is known as transversal telemedicine when practiced among health care professionals (HCPs).

OBJECTIVE

We describe the experience of implementing our telemedicine Eumeda platform for HCPs over the last 10 years.

METHODS

A web-based informatics platform was developed that had continuously updated hypertext created using advanced technology and the following features: security, data insertion, dedicated software for image analysis, and the ability to export data for statistical surveys. Customizable files called "modules" were designed and built for different fields of medicine, mainly in the ophthalmology subspecialty. Each module was used by HCPs with different authorization profiles.

IMPLEMENTATION (RESULTS)

Twelve representative modules for different projects are presented in this manuscript. These modules evolved over time, with varying degrees of interconnectivity, including the participation of a number of centers in 19 cities across Italy. The number of HCP operators involved in each single module ranged from 6 to 114 (average 21.8, SD 28.5). Data related to 2574 participants were inserted across all the modules. The average percentage of completed text/image fields in the 12 modules was 65.7%. All modules were evaluated in terms of access, acceptability, and medical efficacy. In their final evaluation, the participants judged the modules to be useful and efficient for clinical use.

CONCLUSIONS

Our results demonstrate the usefulness of the telemedicine platform for HCPs in terms of improved knowledge in medicine, patient care, scientific research, teaching, and the choice of therapies. It would be useful to start similar projects across various health care fields, considering that in the near future medicine as we know it will completely change.

Introducing Telemedicine in Italy: Citizens' Awareness of a New Healthcare Resource

In recent years, especially during the COVID-19 pandemic, new technologies have emerged as useful resources in healthcare. Telemedicine services may decrease opportunities for contagion by limiting direct medical contacts; they can lead to greater access to and better quality of care, especially for the elderly and chronically ill patients. However, there are still some difficulties in their widespread use, such as lack of knowledge about the effectiveness and safety of telemedicine; lack of awareness of its existence; privacy issues; and lack of computer literacy. The aim of this study is to assess the awareness of and attitude toward telemedicine in the Italian adult population, considering sociodemographic characteristics and territorial differences in telemedicine service implementation. A questionnaire was administered to Italian citizens from October 2022 to February 2023 using communication and social media in order to collect sociodemographic and health characteristics and data on awareness and use of telemedicine services. Less than half of the respondents (n = 1002) were aware of telemedicine services in their region; most of them did not use the available services due to a preference for in-person visits or lack of need. More than 90% of participants who used these services were satisfied with them. A negative attitude toward telemedicine was found in a higher proportion of older adults. This study demonstrated that, although telemedicine services are active in Italy, a large part of the population ignores its availability. Therefore, further efforts should be made to increase citizens' awareness and the use of telemedicine in our country.

Evaluation of remote assessment reliability in the follow-up of patients with diabetic macular edema

PURPOSE

To compare the reliability of office versus remote assessments in the decision to use intravitreal injection for patients with diabetic macular edema (DME).

METHOD

We retrospectively evaluated office and remote assessments for decision agreement regarding treatment by intravitreal injection or non-treatment for DME. Remote assessment consisted in remote evaluation of patient medical data by three reviewers with different skills. Two OCT analysis strategies were performed with the same office assessment data: 1) macular mapping with only two OCT B-scans passing through the fovea, and 2) macular mapping with complete macular scans. Agreement for treatment decisions and OCT analysis strategies were analysed using Cohen's Kappa coefficient (κ).

RESULTS

Data from 49 patients (96 eyes) were included. Treatment decision agreement with two OCT B-scans passing through the fovea was considered excellent for all reviewers (κ between 0.80 and 0.85, varying between reviewers). Treatment decision agreement with complete macular scans was considered excellent (κ between 0.85 and 0.93, varying between reviewers). Agreement between the two OCT analysis strategies and reviewers was considered excellent.

CONCLUSION

Remote assessment in a telemedicine model can be a useful alternative for DME patient follow-up.

Telemedicine for the Diagnosis and Management of Age-Related Macular Degeneration: A Review

Use of ophthalmic telemedicine for patients with age-related macular degeneration (AMD) has shown remarkable advances over recent years. The recent COVID pandemic accelerated this transition since in-person evaluation of elderly patients at high risk for advanced AMD and severe vision loss were also at higher risk for complications from COVID infection. To date, ophthalmic telemedicine has been successfully used in remote retinal consultation by general ophthalmologists for AMD management, hybrid testing visits with both in-office testing and remote evaluation, as well as early successes in home-based remote monitoring of patients with high-risk AMD. We therefore review the current literature and evidence base related to ophthalmic telemedicine for AMD.

RPE65-Associated Retinopathies in the Italian Population: A Longitudinal Natural History Study

Purpose

To investigate the course of inherited retinal degenerations (IRD) due to mutations in the RPE65 gene.

Methods

This longitudinal multicentric retrospective chart-review study was designed to collect best corrected visual acuity (BCVA), Goldman visual field, optical coherence tomography (OCT), and electroretinography (ERG) measurements. The data, including imaging, were collected using an electronic clinical research form and were reviewed at a single center to improve consistency.

Results

From an overall cohort of 60 Italian patients with RPE65-associated IRD, 43 patients (mean age, 27.8 ± 19.7 years) were included and showed a mean BCVA of 2.0 ± 1.0 logMAR. Time-to-event analysis revealed a median age of 33.8 years and 41.4 years to reach low vision and blindness based on BCVA, respectively. ERG (available for 34 patients) showed undetectable responses in most patients (26; 76.5%). OCT (available for 31 patients) revealed epiretinal membranes in five patients (16.1%). Central foveal thickness significantly decreased with age at a mean annual rate of −0.6%/y (P = 0.044). We identified 43 different variants in the RPE65 gene in the entire cohort. Nine variants were novel. Finally, to assess genotype-phenotype correlations, patients were stratified according to the number of RPE65 loss-of-function (LoF) alleles. Patients without LoF variants showed significantly (P < 0.05) better BCVA compared to patients with one or two LoF alleles.

Conclusions

We described the natural course of RPE65-associated IRD in an Italian cohort showing for the first time a specific genotype-phenotype association. Our findings can contribute to a better management of RPE65-associated IRD patients.

The safety and feasibility of the screening for retinopathy of prematurity assisted by telemedicine network during COVID-19 pandemic in Wuhan, China

Background

During the coronavirus disease 2019 (COVID-19) epidemic, due to the traffic blockade and the shortage of medical resources, more and more premature infants could not receive timely and effective ROP screening, which delayed treatment and even caused children blindness. Therefore, how to carry out ROP screening safely and effectively during the epidemic was very important and urgent. This study aimed to evaluate the safety and feasibility of ROP screening assisted by telemedicine network during COVID-19 outbreak.

Methods

This retrospective study was conducted at Wuhan Children’s hospital in Wuhan, China, from January to October, 2020. The measures which were performed to make the ROP screening more safe and effective were summarized and the comparison between ROP screening assisted by telemedicine network in 2020 and usual screening in 2019 were analyzed.

Results

A total of 267 outpatient infants completed ROP screening. The median gestational age was 32 weeks (30w to 34w) and the median birth weight was 1780 g (1460 g to 2100 g). Meanwhile, 149 (55.8%) out of 267 infants were males. During January to May in 2020, 86 screening appointments were received, among which 67 (77.9%) were from telemedicine platform online. The completing percentage of total online ROP appointments was higher than that of total face-to-face appointments (58.1% VS 22. 1%, P = 0.018). As for the number of infants screened between 2020 and 2019 from Februaryto October, 54 infants completed ROP screening in 2020, which was higher than that (51participants) in 2019 on September. Furthermore, compared with the usual screening in 2019, ROP screening assisted by telemedicine network in 2020 had smaller gestational age (32w VS 33w, p<0.001) and lower birth weight (1780 g VS 1900 g, p = 0.001). However, of the 267 infants screened, 18(6.7%) had ROP while the percentage of ROP screened in 2019 was the same (44[6.7%]). During follow-up, none of medical staffs was infected and no adverse reaction was reported.

Conclusions

The screening for retinopathy of prematurity assisted by telemedicine network was safe and feasible during the COVID-19 pandemic. Preventive measures before and after screening were very necessary, which could effectively avoid cross infection.

[Telemedicine monitoring for AMD patients]

INTRODUCTION

AMD follow-up is a public health issue in developed countries due to aging of the population and medical demographics. Telemedicine may be a means of improving follow-up.

PURPOSE

To compare the agreement between telemedicine and in-person consultations in terms of indications for intravitreal injections in exudative AMD patients.

MATERIALS AND METHODS

From January 2017 to April 2017, AMD patients followed on a PRN protocol at a single center, Rennes university medical center, were included. The telemedicine evaluation was read by two anonymous experts on the basis of the medical record including visual acuity and fundus photographs. The agreement between conventional follow-up and telemedicine in terms of indications for intravitreal injections, as well as interobserver agreement, were tested with the Cohen's kappa coefficient using SAS statistical software V9.4 (SAS Institute, Cary, NC).

RESULTS

In total, 104 eyes corresponding to 57 consultations for 42 patients were analyzed. The mean age was 82.12 years (standard deviation±6.4). Recommendations for anti-VEGF were similar between the standard and telemedicine visits in 97 % of cases. The Kappa coefficient was 0.8861 [0.76; 1.00], P<0.0001 for agreement between telemedicine and in-person consultation. The Kappa coefficient was 0.8441 [0.70; 0.99], P<0.0001 for interobserver agreement. We observed 5 cases of disagreement between the two observers.

DISCUSSION

The concordance was very good in our study. The few cases of disagreement resulted mainly from poorly interpretable examinations due to poor image quality, major macular changes in patients with a prior examination, and the fact that only a single cut was analyzed.

CONCLUSION

AMD monitoring by telemedicine seems promising and reliable. This approach would allow better follow-up of patients with difficult access to care.

Telemedicine for Age-Related Macular Degeneration

Background: As the leading cause of vision loss in the United States, age-related macular degeneration (AMD) would seem to be amenable to interventions that increase access to screening and management services for patients. AMD poses several unique challenges for telemedicine, however. The disease lacks clinical consensus on the effectiveness and cost-effectiveness of screening the general population, and more complex imaging modalities may be required than for what has traditionally been used for diabetic retinopathy telehealth systems. Methods: The current literature was reviewed to find clinical trials and expert consensus documents on the state-of-the-art of telemedicine for AMD. Results: A range of feasibility studies have reported success with telemedicine strategies for AMD. Several investigators have reported experience with AMD screening and remote-monitoring systems as well as artificial intelligence applications. Conclusions: There are currently no large-scale telemedicine programs for either screening or managing AMD, but new approaches to screening and managing the condition may allow for expansion of high-quality convenient care for an increasing patient population.

Novel grid combined with peripheral distortion correction for ultra-widefield image grading of age-related macular degeneration

Purpose

Eyes with age-related macular degeneration (AMD) often harbor pathological changes in the retinal periphery and perimacular region. These extramacular changes have not been well classified, but may be phenotypically and functionally relevant. The purpose of this study was to demonstrate a novel grid to systematically study peripheral retinal abnormalities in AMD using geometric distortion-corrected ultra-widefield (UWF) imaging.

Methods

This is a cross-sectional observational case series. Consecutive patients with AMD without any other coexisting vitreoretinal disease and control patients over age 50 without AMD or any other vitreoretinal disease were imaged using Optos 200 Tx. Captured 200° UWF images were corrected for peripheral geometric distortion using Optos transformation software. A newly developed grid to study perimacular and peripheral abnormalities in AMD was then projected onto the images.

Results

Peripheral and perimacular changes such as drusen, retinal pigment epithelium changes and atrophy were found in patients with AMD. The presented grid in conjunction with geometric distortion-corrected UWF images allowed for systematic study of these peripheral changes in AMD.

Conclusion

We present a novel grid to study peripheral and posterior pole changes in AMD. The grid is unique in that it adds a perimacular zone, which may be important in characterizing certain phenotypes in AMD. Our UWF images were corrected for geometric peripheral distortion to accurately reflect the anatomical dimensions of the retina. This grid offers a reliable and reproducible foundation for the exploration of peripheral retinal pathology associated with AMD.

Current barriers to treatment for wet age-related macular degeneration (wAMD): findings from the wAMD patient and caregiver survey

Purpose

A cross-sectional survey to evaluate the current management of wet age-related macular degeneration (wAMD) and to identify barriers to treatment from a patient and caregiver perspective.

Methods

An ophthalmologist-devised questionnaire was given to a global cohort of patients who were receiving (or had previously received) antivascular endothelial growth factor injections and to caregivers (paid and unpaid) to evaluate the impact of wAMD on their lives.

Results

Responders included 910 patients and 890 caregivers; wAMD was diagnosed in both eyes in 45% of patients, and 64% had been receiving injections for > 1 year. Many caregivers were a child/grandchild (47%) or partner (23%) of the patient; only 7% were professional caregivers. Most (73%) patients visited a health care professional within 1 month of experiencing vision changes and 54% began treatment immediately. Most patients and caregivers reported a number of obstacles in managing wAMD, including the treatment itself (35% and 39%, respectively). Sixteen percent of patients also missed a clinic visit.

Conclusion

Most patients seek medical assistance promptly for a change in vision; however, about a quarter of them do not. This highlights a lack of awareness surrounding eye health and the impact of a delayed diagnosis. Most patients and caregivers identified a number of obstacles in managing wAMD.
