Project description:IntroductionCOVID-19 has disrupted how ophthalmic practice is conducted worldwide. One patient population that may suffer from poor outcomes during the pandemic are those with age-related macular degeneration (AMD). Many practices are performing some form of tele-ophthalmology services for their patients, and guidance is needed on how to maintain continuity of care amongst patients with AMD using tele-ophthalmology.MethodsA literature search was conducted, ending 1 August 2020, to identify AMD outcomes and telecare management strategies that could be used during the COVID-19 pandemic.Results237 total articles were retrieved, 56 of which were included for analysis. Four American Academy of Ophthalmology and Center for Disease Control web resources were also included.DiscussionRisk-stratification models have been developed that let providers readily screen existing patients for their future risk of neovascular AMD (nAMD). When used with at-home monitoring devices to detect nAMD, providers may be able to determine who should be contacted via tele-ophthalmology for screening. Telemedicine triage can be used for new complaints of vision loss to determine who should be referred to a retinal specialist for management of suspected nAMD. To increase access and provider flexibility, smartphone fundus photography images sent to a centralized tele-ophthalmology service can aid in the detection of nAMD. Considerations should also be made for COVID-19 transmission, and tele-ophthalmology can be used to screen patients for the presence of COVID-19 prior to in-person office visits. Tele-ophthalmology has additional utility in connecting with nursing home, rural, and socioeconomically disadvantaged patients in the post-pandemic period.

Project description:ObjectiveThe aim of the study is to report the creation of a flipped ophthalmology course and preclinical medical student perceptions and knowledge gains before and after a flipped ophthalmology course.DesignThe form of the study discussed is an observational study.SubjectsThe subjects involved in the study are second-year (U.S.) United States medical students at the University of Miami, Miller School of Medicine (n = 401).MethodsSecond-year medical students participated in a 1-week "flipped classroom" ophthalmology course geared toward primary care providers at the University of Miami, Miller School of Medicine. Eleven hours of traditional classroom lectures were condensed into 4.5 hours of short videos with self-assessment quizzes, small group discussions, and a large group case-based discussion. Fifty-seven short videos (<9 minutes) focused on major ophthalmology topics and common conditions were viewed by the students at their leisure. Students completed a pre- and post-course evaluation on their perceptions and opinions of the flipped classroom approach. Final exam scores in the flipped classroom cohort were compared with the final exam scores in the traditional didactic format used in years prior.Main outcome measuresThe main outcome measures include: student final exam performance; student satisfaction, opinions, and perceptions.ResultsOver the course of 2 years, 401 second-year U.S. medical students participated in the flipped classroom ophthalmology course. The majority of students enjoyed the flipped classroom experience (75.3%) and expressed interest in using the approach for future lessons (74.6%). The flipped classroom videos were preferred to live lectures (61.2%). Over 90% of students stated the self-assessment quizzes were useful, 79% reported that the small group discussions were an effective way to apply knowledge, and 76% cited the large group case-based discussion as useful. Pre-course knowledge assessment scores averaged 48%. Final examination scores in the flipped group (average ± standard deviation [SD] = 92.1% ± 6.1) were comparable to that of the traditional group when evaluating identical questions (average ± SD = 91.7% ± 5.54), p = 0.34.ConclusionThe flipped classroom approach proved to be a well-received and successful approach to preclinical medical education for ophthalmology. This was achieved using 35% less course time than our traditional course. This innovative approach has potential for expansion to other medical schools, medical education abroad, and for other medical school modules.

Project description:BackgroundEight-four percent of people own smartphones and view them 14 billion times daily, making them potential vectors for environmental hazards such as allergens, β-D-glucans (BDGs), and endotoxin. Whether these toxins are prevalent and the effectiveness of cleaning solutions targeting these agents on smartphones have not been studied.ObjectiveWe sought to determine (1) whether phones are reservoirs of allergen, endotoxin, and BDGs and (2) if present, whether their levels can be effectively reduced by using specific cleaning methods.MethodsElectrostatic wipes used to wipe the phones of 15 volunteers were tested to determine their allergen, BDG, and endotoxin levels. Cleaning interventions were done on simulated phone models; 70% isopropyl alcohol, 0.184% benzyl and ethyl benzyl ammonium chloride (Clorox nonbleach [The Chlorox Company, Oakland, Calif]), 0.12% chlorhexidine, 0.05% cetylpyridinium, 3% benzyl benzoate, and 3% tannic acid wipes were used and compared with wipes with no solution (the control).ResultsThe smartphones showed high and variable levels of BDG and endotoxin. Cat and dog allergens were found mostly on the smartphones of pet owners. The combination of chlorhexidine and cetylpyridinium significantly reduced BDG levels (mean 269 ng/wipe vs 1930 ng/wipe for the control [P < .05]) and endotoxin, (mean 349 vs 1320 endotoxin units/wipe for the control [P < .05]). The combination of benzyl benzoate and tannic acid significantly reduced the levels of cat and dog allergens (dog, mean level of 14 ng/wipe versus 407 ng/wipe for the control [P < .001]; cat, mean level of 55 ng/wipe versus 1550 ng/wipe for the control [P < .001]). The combination mixture solutions had the greatest reductions compared with the control.ConclusionsThere are elevated levels of BDG, allergens, and endotoxin on smartphones. The combination of chlorhexidine and cetylpyridinium was the most effective in reducing BDG and endotoxin levels, and the combination of benzyl benzoate and tannic acid was most effective in reducing cat and dog allergen levels on smartphones.

Project description:BackgroundSustaining Basic Life Support (BLS) training during the COVID-19 pandemic bears substantial challenges. The limited availability of highly qualified instructors and tight economic conditions complicates the delivery of these life-saving trainings. Consequently, innovative and resource-efficient approaches are needed to minimize or eliminate contagion while maintaining high training standards and managing learner anxiety related to infection risk.MethodsIn a non-inferiority trial 346 first-year medical, dentistry, and physiotherapy students underwent BLS training at AIXTRA-Competence Center for Training and Patient Safety at the University Hospital RWTH Aachen. Our objectives were (1) to examine whether peer feedback BLS training supported by tele-instructors matches the learning performance of standard instructor-guided BLS training for laypersons; and (2) to minimize infection risk during BLS training. Therefore, in a parallel group design, we compared arm (1) Standard Instructor Feedback (SIF) BLS training (Historical control group of 2019) with arm (2) a Tele-Instructor Supported Peer-Feedback (TPF) BLS training (Intervention group of 2020). Both study arms were based on Peyton's 4-step approach. Before and after each training session, objective data for BLS performance (compression depth and rate) were recorded using a resuscitation manikin. We also assessed overall BLS performance via standardized instructor evaluation and student self-reports of confidence via questionnaire. Non-inferiority margins for the outcome parameters and sample size calculation were based on previous studies with SIF. Two-sided 95% confidence intervals were employed to determine significance of non-inferiority.ResultsThe results confirmed non-inferiority of TPF to SIF for all tested outcome parameters. A follow-up after 2 weeks found no confirmed COVID-19 infections among the participants.ConclusionTele-instructor supported peer feedback is a powerful alternative to in-person instructor feedback on BLS skills during a pandemic, where infection risk needs to be minimized while maximizing the quality of BLS skill learning.Trial registrationhttps://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00025199, Trial ID: DRKS00025199.

Project description:BackgroundTo synthesize high-quality evidence to compare traditional in-person screening and tele-ophthalmology screening.MethodsOnly randomized controlled trials (RCTs) were included in this systematic review and meta-analysis. The intervention of interest was any type of tele-ophthalmology, including screening of diseases using remote devices. Studies involved patients receiving care from any trained provider via tele-ophthalmology, compared with those receiving equivalent face-to-face care. A search was executed on the following databases: Medline, EMBASE, EBM Reviews, Global Health, EBSCO-CINAHL, SCOPUS, ProQuest Dissertations and Theses Global, OCLC Papers First, and Web of Science Core Collection. Six outcomes of care for age-related macular degeneration (AMD), diabetic retinopathy (DR), or glaucoma were measured and analyzed.ResultsTwo hundred thirty-seven records were assessed at the full-text level; six RCTs fulfilled inclusion criteria and were included in this review. Four studies involved participants with diabetes mellitus, and two studies examined choroidal neovascularization in AMD. Only data of detection of disease and participation in the screening program were used for the meta-analysis. Tele-ophthalmology had a 14% higher odds to detect disease than traditional examination; however, the result was not statistically significant (n = 2,012, odds ratio: 1.14, 95% confidence interval (CI): 0.52-2.53, p = 0.74). Meta-analysis results show that odds of having DR screening in the tele-ophthalmology group was 13.15 (95% CI: 8.01-21.61; p < 0.001) compared to the traditional screening program.ConclusionsThe current evidence suggests that tele-ophthalmology for DR and age-related macular degeneration is as effective as in-person examination and potentially increases patient participation in screening.

Project description:Community transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID-19) in the United States on February 26, 2020, and the rapid spread that followed forced patients, providers, payors, and policy makers to adapt to an unprecedented, nearly instant, and enormous demand for virtual care. Although few US ophthalmology practices incorporated telemedicine prior to COVID-19, its use has now become the norm. Regarding the use of synchronous patient-to-provider virtual visits (SPPVV) in pediatric ophthalmology, we have pooled our collective experience at three academic practices across the country to describe initial workflows, technology solutions, use cases, and barriers to care.

Project description:Augmented reality (AR) has come a long way from a science-fiction concept to a science-based reality. AR is a view of the real, physical world in which the elements are enhanced by computer-generated inputs. AR is available on mobile handsets, which constitutes an essential e-learning platform. Today, AR is a real technology and not a science-fiction concept. The use of an e-ophthalmology platform with AR will pave the pathway for new-age gameful pedagogy. In this manuscript, we present a newly innovated AR program named "Eye MG AR" to simplify ophthalmic concept learning and to serve as a new-age immersive 3D pedagogical tool for gameful learning.

Project description:In hospitals, effective and efficient communication among care providers is critical to the provision of high-quality patient care. Yet, major problems impede communications including the frequent use of interruptive and one-way communication paradigms. This is especially frustrating for frontline providers given the dynamic nature of hospital care teams in an environment that is in constant flux.We conducted a pre-post evaluation of a commercially available secured messaging mobile application on 4 hospital units at a single institution for over one year. We included care providers on these units: residents, hospitalists, fellows, nurses, social workers, and pharmacists. Utilization metrics and survey responses on clinician perceptions were collected and analyzed using descriptive statistics, the Kruskal-Wallis test, and Mann-Whitney U test where appropriate.Between May 2013 and June 2014, 1,021 providers sent a total of 708,456 messages. About 85.5% of total threads were between two providers and the remaining were group messages. Residents and social workers/clinical resource coordinators were the largest per person users of this communication system, sending 9 (IQR 2-20) and 9 (IQR 2-22) messages per person per day, and receiving 18 (IQR 5-36) and 14 (IQR 5-29) messages per person per day, respectively (p=0.0001). More than half of the messages received by hospitalists, residents, and nurses were read within a minute. Communicating using secured messaging was found to be statistically significantly less disruptive to workflow by both nursing and physician survey respondents (p<0.001 for each comparison).Routine adoption of secured messaging improved perceived efficiency among providers on 4 hospital units. Our study suggests that a mobile application can improve communication and workflow efficiency among providers in a hospital. New technology has the potential to improve communication among care providers in hospitals.

Project description:IntroductionThis study aims to investigate the diagnostic accuracy of store-and-forward tele-ophthalmology consultations for non-diabetic patients, aged 40 and above, presenting with vision impairment of 3 months or more, in terms of cataracts, glaucoma, and age-related macular degeneration.MethodsThis is a prospective comparative study. Enrolled subjects were independently assessed by both tele-ophthalmology and face-to-face assessment. Agreement level between the two modalities for diagnosis and severity were compared using kappa statistic. Diagnostic accuracy of tele-ophthalmology was determined using the face-to-face consultation serving as the gold standard. Costs were compared by calculating the downstream costs generated by each modality in terms of investigations and treatment.ResultsA total of 860 eyes of 430 patients were assessed during the study period. Tele-ophthalmology consultations had significantly high agreement with face-to-face consultations in the diagnosis and grading of all three ocular conditions; cataracts, glaucoma, and AMD. Diagnosis and grading of cataracts and AMD reached [Formula: see text] values of > 0.8, while diagnosis and grading of glaucoma reached [Formula: see text] values between 0.61 and 0.8. In terms of diagnostic accuracy, tele-ophthalmology consultations were highly sensitive and specific for AMD with greater than 99% sensitivity and specificity achieved by tele-ophthalmology. There was high specificity when diagnosing cataracts, but lower sensitivity at 87.8%. Conversely, there was high sensitivity for diagnosing glaucoma, but lower specificity at 76.5%. Downstream costs were similar between groups.ConclusionsStore-and-forward tele-ophthalmology consultations are accurate and comparable to face-to-face consultations for diagnosis and grading of cataracts, glaucoma, and AMD.
