Prevalence of diabetic retinopathy and self-reported barriers to eye care among patients with diabetes in the emergency department: the diabetic retinopathy screening in the emergency department (DRS-ED) study.

BACKGROUND: Screening for diabetic retinopathy (DR) is suboptimal, and patients with diabetes who present to the emergency department (ED) may be at particularly high risk of undiagnosed DR. The purpose of this study is to determine the prevalence of DR among diabetic patients who present to the ED of our tertiary medical center using teleophthalmology and to assess self-reported barriers to eye care. METHODS: This cross-sectional, single-institution study recruited clinically stable diabetic patients who presented to the ED during daytime hours over 29 total weekdays across 2 months in 2018 and 2019. Participants had nonmydriatic, 45-degree, single-field digital retinal photographs taken on site (Digital Retinal System, Centervue). Following retinal imaging, participants then completed a survey about barriers to regular eye care and their acceptance of potential interventions to promote screening. Digital retinal photographs were interpreted remotely by a board-certified ophthalmologist and communicated to participants' primary care physician and/or endocrinologist. RESULTS: Over the study period, 275 ED patients had a documented diagnosis of diabetes, of whom 167 were deemed clinically stable for the study and 141 were invited to participate. Sixty-four were enrolled, of whom 50 had gradable-quality fundus images (78%). Of these 50 patients, almost all had type 2 diabetes (47, 94%), with an average disease duration of 12 ± 9 years and mean hemoglobin A1c of 8.1 ± 2.0% (mmol/mol). Based on fundus photography, 14 patients (28%) were diagnosed with DR, which was newly diagnosed for 10 (20% of the total study population). Severity was most commonly mild or moderate (12/14, 86%), with 1 case of severe nonproliferative DR and 1 proliferative DR. The majority (26, 52%) reported at least one barrier to routine eye care in our self-administered survey, of which having too many appointments (6, 12%) and cost (5, 10%) were frequently cited as most important. The majority were receptive to interventions to promote DR screening, including reminder phone calls (29, 58%) and text messages (28, 56%). CONCLUSIONS: Digital fundus photography in the ED detected a high rate of undiagnosed DR. Half of participants reported barriers to routine care, and most were receptive to messaging interventions to schedule an eye exam. Future studies are warranted to assess scalability of ED-based screening programs and their follow-through rates.

Evaluation of Diplopia by Emergency Medicine Physicians and Consulting Neurologists.

BACKGROUND: Appropriate evaluation of diplopia requires separating serious from benign causes. If providers are not adept in this task, diagnosis of critical conditions may be delayed and unnecessary testing may result. METHODS: We studied the records of 100 consecutive patients who presented to an emergency department between 2010 and 2020 with diplopia as a prominent symptom. We rated the performance of emergency medicine physicians (EMPs) and consulting neurologists (CNs) in the examination, diagnosis, and ordering of diagnostic tests according to standards based on neuro-ophthalmologic consultation and the neuro-ophthalmologic literature. RESULTS: EMPs made no diagnosis or an incorrect diagnosis in 88 (88%) of 100 encounters. They ordered 14 unindicated and 12 incorrect studies, mostly noncontrast computed tomography scans. CNs made an incorrect diagnosis in 13 (31%) encounters. They ordered 6 unindicated and 2 incorrect studies. The total charge for unindicated and incorrect studies ordered by EMPs and CNs was $119,950. CONCLUSIONS: EMPs and CNs made frequent errors in the examination, diagnosis, and ordering of diagnostic studies, leading to inefficient care and unnecessary testing. EMPs largely delegated the evaluation of diplopia to their consultants. If such consultative support were not available, the care of diplopic patients would be delayed. CNs performed more complete examinations, but rarely enough to allow appreciation of the pattern of ocular misalignment, contributing to misdiagnoses and ordering errors. The identification of these provider errors allows for more targeted teaching in the evaluation of diplopia.

Accuracy Assessment of Outpatient Telemedicine Encounters at an Academic Ophthalmology Department.

Purpose We assess the clinical accuracy of direct-to-patient real-time outpatient video visit encounters at our eye center. Design This was a retrospective longitudinal study. Subjects and Methods Patients who completed a video visit over a 3-week period between March and April 2020 were included. Accuracy assessment was determined by comparing diagnosis and management from the video visit with subsequent in-person follow-up over the next year. Results A total of 210 patients (mean age 55±18 years) were included, of whom 172 (82%) were recommended a scheduled in-person follow-up encounter after their video visit. Among the 141 total patients who completed in-person follow-up, 137 (97%) had a diagnostic agreement between telemedicine and in-person evaluation. Management plan agreed for 116 (82%), with the remainder of visits either escalating or deescalating treatment upon in-person follow-up with little substantive change. Compared with established patients, new patients had higher diagnostic disagreement following video visits (12 vs. 1%, p =0.014). Acute visits trended toward more diagnostic disagreement compared with routine visits (6 vs. 1%, p =0.28) but had a similar rate of management change on follow-up (21 vs. 16%, p =0.48). New patients were more likely to have early unplanned follow-up than established patients (17 vs. 5%, p =0.029), and acute video visits were associated with unplanned early in-person assessments compared with routine video visits (13 vs. 3%, p =0.027). There were no serious adverse events associated with the use of our telemedicine program in the outpatient setting. Conclusions Video visits had high diagnostic and management agreement with subsequent in-person follow-up encounters.

Initial Results and Patient Survey of Virtual Inpatient Ophthalmology Consultations During the COVID-19 Pandemic.

Purpose: To examine the uptake, results, and patient assessment of virtual inpatient ophthalmology consultations at our academic medical center during the COVID-19 pandemic.Design: Retrospective review, pre and post COVID analysis, and teleophthalmology patient survey in the inpatient and emergency setting.Participants: Adult patients at our medical center for whom ophthalmology consultation was requested from February 24 through April 19, 2020.Methods: Patient encounters were retrieved and coded for all inpatient and emergency room ophthalmology consultations over a 4-week period before and a 4-week period after our department first offered virtual ophthalmology consultations. Theseconsultations took place over real-time video, audio, or photography between the on-call ophthalmologist and the patient and/or patient's primary physician. A four-item questionnaire was offered to patients who completed a virtual consultation.Main Outcome Measures: Virtual consultation diagnoses and management outcomes; patient assessment of virtual inpatient and emergent ophthalmic care.Results: Of all 423 included encounters, 258 (61%) occurred during the 4 weeks before offering virtual consultations and 165 (39%) encounters occurred during the subsequent 4-week period, indicating a 36% decrease in ophthalmology consultations over this pandemic period. A total of 120 (28%) encounters were conducted remotely during the 8-week period. In-person emergency department (ED) encounters (as percent of total encounters) decreased from 60% to 36% (p < .01) between the first and eighth weeks of the study period. In the 4 weeks since their implementation, virtual inpatient ophthalmology consultations were utilized in 34 of 165 (21%) consultations. Of those, 20 (59%) were high acuity and 1 (3%) was escalated to the ED for in-person evaluation. Most common management decisions made included medication prescription in 46 (55%) patients and scheduling follow-up for 44 (30%) patients. In a survey administered to all 120 patients who were managed over phone or video, 56 (47%) responded. Respondents were in general agreement (Cronbach's alpha = 0.92) and expressed satisfaction with phone and virtual encounters. Specifically, 42 (49%) of 86 patients who had phone encounters noted a mean weighted satisfaction score of 4.6 out of 5 and 14 (41%) responders of 34 virtual consultation encounters noted a mean weighted satisfaction score of 4.9 out of 5. The difference between the average weighted satisfaction scores favored virtual consultation over telephone encounters (p < .01).Conclusions: Virtual inpatient ophthalmology consultations are feasible and have reported high patient satisfaction. Implementing video-based technologies to deliver high-acuity ophthalmic triage and management may help to promote patient and provider safety. In our experience, patients favored virtual consultation over telephone encounters.

A Required Ophthalmology Rotation: Providing Medical Students with a Foundation in Eye-Related Diagnoses and Management.

Introduction: Current ophthalmologic training in medical school is inadequate in preparing medical students to handle basic eye complaints as nonophthalmology residents. Most medical students are uncomfortable performing eye examinations, but increased ophthalmology training improves confidence in this area. The University of Pittsburgh School of Medicine (UPSOM) teaches students the basics of ophthalmology with a required 1-week rotation during the 1-month specialty care clerkship (SCC), providing students with skills to perform rudimentary eye examinations as nonophthalmology providers. Methods: Within a 1-week ophthalmology rotation, we developed a series of interactive case-based teaching sessions, handouts, and homework that accompanied clinical instruction to familiarize third- and fourth-year medical students with ophthalmic equipment, terminology, diagnosis, and management. Of learners, 67 (roughly 11 per cohort) rotated on six consecutive SCCs beginning in May 2019. All learners completed an in-house exam and received resident clinical evaluations at the end of their rotation. Results: Of the 64 participants who responded to the survey, 100% rated the quality of teaching sessions outstanding or good, and 83% of students strongly agreed or agreed with the statement, "I believe the overall teaching in the ophthalmology clinical settings was good quality." The average clinical and exam score for ophthalmology over 6 months was 4.5 out of 5, and 83% respectively. Discussion: Generally positive student feedback as well as high clinical and exam scores suggested that the required UPSOM ophthalmology clerkship was both engaging and effective. This course can be easily adapted to teach students at other medical institutions.

Incorporating Video Visits into Ophthalmology Practice: A Retrospective Analysis and Patient Survey to Assess Initial Experiences and Patient Acceptability at an Academic Eye Center.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has led to rapid adoption of teleophthalmology to deliver eyecare remotely. The purpose of our study was to assess the implementation and patient acceptability of video consultation for outpatient ophthalmic care at our institution. METHODS: We conducted a retrospective, cross-sectional analysis and patient survey of adult patients who completed a virtual video visit at our institution from 18 March 18 through to 27 April 2020. All video visit encounters were assessed for patient characteristics, diagnoses, management, and follow-up outcomes. Patients were surveyed for their feedback on acceptability and utility of their virtual video consultation. RESULTS: A total of 219 patients (mean age 55 years; range 21-89 years) completed 231 video visit encounters at our department over a 6-week period, of whom 118 were women (54%). About half of these encounters were acute visits (102 visits, 47%). The most common diagnosis of these visits was postoperative state (20 visits, 9% of the total), followed by conjunctivitis (16 visits, 7%), and keratitis (14 visits, 6%). The most common management decisions were medication prescription (102 visits, 46%) or reassurance (86 visits, 39%), while 17 video visit patients (8%) were escalated to an urgent, in-person evaluation. Ninety-two patients completed a follow-up survey (42% response rate), of whom 45 (49%) indicated that they might have delayed seeking care during this pandemic in the absence of a virtual video option. Seventy-two (78%) reported that they would consider participating in a video visit as an alternative to an office-based encounter in the future, and the overall video visit experience was rated highly, with a weighted mean Likert scale rating of 4.3 out of 5 (Cronbach's α = 0.88). CONCLUSION: Virtual video visits may be used to manage a range of ophthalmic complaints. Patients participating in this survey found such video visits acceptable and timesaving, and the majority would consider using video consultations for future eyecare encounters.

Ophthalmology Practice During the Coronavirus Disease 2019 Pandemic: The University of Pittsburgh Experience in Promoting Clinic Safety and Embracing Video Visits.

The coronavirus disease 2019 pandemic has led to widespread change as public health strategies for containment have emphasized social distancing and remaining at home. These policies have led to downscaled clinic volumes, cancellation of elective procedures, enhanced personal protective strategies in the clinic, and adoption of telemedicine encounters. We describe the evidence-based practical approach taken in our ophthalmology department to continue delivering eye care during the pandemic by rescheduling visits, enhancing clinic safety, and adopting virtual video encounters.

Non-Therapeutic Laser Retinal Injury.

BACKGROUND: As lasers have become an increasingly important component of commercial, industrial, military, and medical applications, reported incidents of non-therapeutic laser eye injuries have increased. The retina is particularly vulnerable due to the focusing power and optical transparency of the eye. Continued innovations in laser technology will likely mean that lasers will play an increasingly important and ubiquitous role throughout the world. Critical evaluation should thus be paid to ensure that non-therapeutic injuries are minimized, recognized, and treated appropriately. METHODS: A comprehensive literature review on the PubMed database was conducted to present case reports and case series representative of the variety of laser eye injuries in different injury circumstances, tissue types, and biological damage mechanisms. RESULTS: A general summary of non-therapeutic laser retina injuries is presented, including information about growth of the industry, increasingly accessible online markets, inconsistent international regulation, laser classifications, laser wavelengths, and laser power, mechanisms of tissue injury, and a demonstration of the variety of settings in which injury may occur. Finally, 68 cases found in the literature are summarized to illustrate the presentations and outcomes of these patients. CONCLUSIONS: As non-therapeutic laser eye injuries increase in frequency, there is a greater need for public health, policy, diagnosis, and treatment of these types of injuries.
