Claims-Based Frailty Index and Its Relationship With Commonly Used Clinical Frailty Measures.

The relationship of claims-based frailty index (CFI), a validated measure to identify frail individuals using Medicare data, and frailty measures used in clinical practice has not yet been fully explored. We identified community-dwelling participants of the 2015 National Health and Aging Trends Study (NHATS) whose CFI scores could be calculated using linked Medicare claims. We calculated 9 commonly used clinical frailty measures from theirNHATS in-person examination: Study of Osteoporotic Fracture Index (SOF), FRAIL Scale, Frailty Phenotype, Clinical Frailty Scale (CFS), Vulnerable Elder Survey-13 (VES-13), Tilburg Frailty Indicator (TFI), Groningen Frailty Indicator (GFI), Edmonton Frail Scale (EFS), and 40-item Frailty Index (FI). Using equipercentile method, CFI scores were linked to clinical frailty measures. C-statistics and test characteristics of CFI to identify frailty asdefined by each clinical frailty measure were calculated. Of the 3963 older adults, 44.5% were ≥75 years, 59.4% were female, and 82.3% were non-Hispanic White. A CFI of 0.25 was equipercentile to the following clinical frailty measure scores: SOF 1.4, FRAIL 1.8, Phenotype 1.8, CFS 5.4, VES-13 5.7, TFI 4.6, GFI 5.0, EFS 6.0, and FI 0.26. The C-statistics of using CFI to identify frailty asdefined by each clinical measure were ≥0.70, except for CFS and VES-13. The optimal CFI cutpoints to identify frailty per clinical frailty measure ranged from 0.212 to 0.242, with sensitivity and specificity of 0.37-0.83 and 0.66-0.84, respectively. Understanding the relationship of CFI and commonly used clinical frailty measures can enhance the interpretability and potential utility of CFI.

Safety and efficacy of a new covered stent in hemodialysis vascular access outflow stenosis: A Brazilian multicenter retrospective study.

Vascular stenosis commonly leads to dysfunction in hemodialysis vascular access. Although percutaneous transluminal angioplasty is an established treatment, stent utilization has increased in the last decade as an alternative solution to extend the access function. This study evaluated the safety and initial results of a new impermeable covered stent for treating vascular access outflow stenosis. Investigators retrospectively analyzed 114 hemodialysis patients treated with polytetrafluorethylene-covered stents from September 2018 to September 2022 across four centers. Lesions treated were de novo or restenotic and located in the venous graft anastomosis, outflow segment, cephalic arch, and basilic swing point. Patients were followed by in-person physical examination at 1, 3, and 6 months, and Duplex ultrasound was performed to evaluate the vascular access circuit and in-stent restenosis. The primary efficacy endpoint was target lesion primary patency at 1, 3, and 6 months. Secondary endpoints included access circuit primary patency and secondary patency at 1, 3, and 6 months. The primary safety endpoint was freedom from local or systemic serious adverse events through 30 days post-procedure. Forty-four patients had thrombosed access at the initial presentation, and 41 patients presented with recurrent stenosis. The target lesion primary patency rates at 1, 3, and 6 months were 100%, 89.4%, and 74%, respectively. The access circuit primary patency rates were 100% at 1 month, 85% at 3 months, and 62.7% at 6 months. The secondary patency rates at 1, 3, and 6 months were 100%, 96.4%, and 94.6%, respectively. In the adjusted multivariate Cox regression analysis, only recurrent lesions and female gender were associated with reduced primary patency rates. No serious adverse event was observed through the first 30 days post-procedure. In this retrospective analysis, a new covered stent was shown to be safe and effective for treating peripheral outflow stenosis in vascular access.

Thyrotoxicosis Misdiagnosed as Long Covid by Telemedicine - A Cautionary Tale.

Individuals who have had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may develop post-coronavirus disease conditions, also known as long COVID. The symptoms of long COVID are nonspecific, and there are similarities between the symptoms of long COVID and those of Graves' disease (GD). Therefore, it is important to rule out GD in patients suspected of having long COVID. Telemedicine is widely used to avoid the risk of SARS-CoV-2 infection. However, owing to the lack of in-person examinations, diagnostic errors can occur. A 27-year-old Japanese woman presented complaining of persistent fatigue, dyspnea, and low-grade fever, and after in-person examination was finally diagnosed with GD. She had been diagnosed with SARS-CoV-2 infection four months earlier and her symptoms had resolved within 5 days but then recurred. Subsequently, she had 3 telemedicine visits and had been diagnosed with long COVID. With telemedicine there may be delayed diagnosis of GD in patients with a recent history of SARS-CoV-2 infection. Some symptoms and abnormalities cannot be confirmed in telemedicine visits performed using a simple mobile phone. Therefore it is important to know which findings obtained in telemedicine visits with a simple mobile phone are suggestive of GD. Low-grade fever and tachycardia are often observed in patients with GD, but rarely occur in patients with long COVID. Tachycardia and persistent low-grade fever after SARS-CoV-2 infection, which can be confirmed by telemedicine, can be clues for the diagnosis of GD. Therefore, in-person examination should be added if these symptoms are confirmed by telemedicine. The symptoms of Graves 'disease (GD) and long COVID may overlap.With telemedicine there may be delayed diagnosis of GD, in patients with recent history of severe acute respiratory syndrome mediated by coronavirus 2 (SARS-CoV-2) infections.In telemedicine visits, tachycardia and persistent low-grade fever could be clues for the diagnosis of GD after SARS-CoV-2 infections on telemedicine.

Veterinary telemedicine: A new era for animal welfare.

Telehealth is a rapidly developing field of veterinary medicine, particularly during and after the coronavirus 2019 (COVID-19) pandemic. The world and animal owners' expectations are changing to the point where veterinary practice will need to adapt due to information technology advancements. This narrative review describes the status, benefits, technology basics, applications, limitations, and legal aspects of veterinary telemedicine over the globe. Veterinary telemedicine is a service alongside other veterinary services that meets client needs, delivers quality medicine, and improves animal welfare. The most frequently utilized veterinary telemedicine applications include teleradiology, telesonography, teledentistry, telecardiology, telerehabilitation, anesthesia teleconsultation, telehospice and telepalliative care, telecytology, tele-endoscpy, teledermatology, tele-ophthalmology, tele-behavior therapy, and veterinary education and training. Veterinary telemedicine has a bright near future and will impact veterinary medicine and animal welfare due to its numerous advantages. These advantages include its low cost, availability, involvement in veterinary health care, online payment, and effectiveness in many clinical situations such as follow-up after an in-person examination, inspection of surgical sites, or mobility. Nevertheless, veterinary telemedicine should receive more attention from veterinary professional regulatory bodies in all countries. Moreover, it is necessary to conduct more studies to evaluate how telehealth is beginning to improve veterinary care, particularly for underserved regions.

Bipartitism in Tarsal Bones: A Retrospective Analysis of Clinical and Radiological Features

Background: Bipartitism in the foot, especially in the tarsal bones, is a rare anatomical variant characterised by dividing one bone into two separate ossification centers. This condition can be congenital or acquired, often remains asymptomatic, and is only discovered incidentally during radiological imaging. This study aims to present a comprehensive retrospective analysis of bipartitism in tarsal bones, assessing its prevalence, type of articulation and associated clinical features in a cohort of patients. Methods: A total of 4,645 patients were retrospectively evaluated from 6,145-foot images consisting of 4,975 computed tomography (CT) and 1,170 magnetic resonance imaging (MRI) scans obtained between 2015 and 2023. 15 patients with tarsal bipartitism were identified and contacted through the hospital system for in-person medical history and examination. Radiological exams assessed partial and complete bipartition, diastasis, and exostosis in the tarsal bones. Age, sex, side, trauma history, pain, foot deformity, gait disturbance, and other clinical findings were also recorded. Results: Bipartitism was detected in 15 patients (0.32%), predominantly affecting males (87%). The most common variant was medial cuneiform bipartitism, observed in 13 patients (0.28%). Talus and calcaneus bipartitism were each observed in one patient (0.02%). Bilateral involvement was present in 67% of the cases, with 60% of patients reporting chronic pain. Complete dissociation of bipartite bones was noted in 80% of cases. Accompanying bipartitism, two patients had pes planovalgus, and one had hallux varus deformity. Conclusion: Although bipartitism of the tarsal bones is rare, it remains a diagnostic challenge due to variability in clinical presentation and possible association with other foot deformities. Accurate diagnosis through advanced imaging techniques is essential to differentiate these variants from fractures and guide appropriate treatment. This study contributes valuable insights into the prevalence and clinical impact of bipartitism in the tarsal bones, emphasising the importance of early diagnosis and individualised treatment strategies.

Tooth Motion Monitoring in Orthodontic Treatment by Mobile Device-based Multi-view Stereo.

Nowadays, orthodontics has become an important part of modern personal life to assist one in improving mastication and raising self-esteem. However, the quality of orthodontic treatment still heavily relies on the empirical evaluation of experienced doctors, which lacks quantitative assessment and requires patients to visit clinics frequently for in-person examination. To resolve the aforementioned problem, we propose a novel and practical mobile device-based framework for precisely measuring tooth movement in treatment, so as to simplify and strengthen the traditional tooth monitoring process. To this end, we formulate the tooth movement monitoring task as a multi-view multi-object pose estimation problem via different views that capture multiple texture-less and severely occluded objects (i.e. teeth). Specifically, we exploit a pre-scanned 3D tooth model and a sparse set of multi-view tooth images as inputs for our proposed tooth monitoring framework. After extracting tooth contours and localizing the initial camera pose of each view from the initial configuration, we propose a joint pose estimation scheme to precisely estimate the 3D pose of each individual tooth, so as to infer their relative offsets during treatment. Furthermore, we introduce the metric of Relative Pose Bias to evaluate the individual tooth pose accuracy in a small scale. We demonstrate that our approach is capable of reaching high accuracy and efficiency as practical orthodontic treatment monitoring requires.

A perspective on the scope of videoconferencing-based telemedicine in respiratory diseases outpatient clinic.

Telemedicine is rapidly expanding across various fields worldwide. While it finds application in respiratory diseases due to the imperative need for protection against the risk of transmission and the close monitoring of patients with chronic diseases, there is a scarcity of publications detailing telemedicine experiences in respiratory diseases. This study aims to retrospectively evaluate the prospective management of patients with respiratory diseases through videoconference-based telemedicine, intending to establish a foundation for its judicious application in pulmonology cases. In this descriptive study, anonymized medical records of all 478 patients assessed via videoconference-based telemedicine over an eight-month period from June 2020 to February 2021 were reviewed. The analysis included demographic characteristics, disease history, attendance methods, the necessity for in-person physical examination after the initial videoconference (VC) session, the inclusion of investigations, pre-diagnosis, diagnosis processes, follow-up period, and outcomes. Follow-up data for all patients included in the study were reviewed at the end of June 2021. Median age of the patients was 55 (44-67), with a male predominance of 55%. Approximately 30% resided in a city other than the one in which the physician offering telemedicine was situated. Seventy-nine (16.7%) individuals received telemedicine via VC sessions without the requirement for any in-person examinations. The most prevalent disease among those who applied for telemedicine was asthma. Median duration of the initial VC session was 13 (8-18) minutes. At least half of the individuals seeking videoconference-based telemedicine for chronic respiratory disorders, such as asthma, COPD, and interstitial lung disease, had previously been followed by either the telemedicine provider or another physician in the same hospital. However, the vast majority of telemedicine applications in disease categories such as COVID, post-COVID, pulmonary nodules, and lung cancer were submitted by first-time applicants. This pioneering study suggests that videoconference-based telemedicine may be an alternative/complementary tool for patients, particularly those with chronic respiratory diseases.

Telehealth in hypertension management: remote monitoring, adherence, and patient outcomes

Hypertension, commonly referred to as high blood pressure, is characterized by consistently elevated blood force against artery walls. Managing hypertension involves lifestyle adjustments and, when necessary, medication. Telehealth is instrumental in transforming hypertension management, utilizing technology to enhance remote monitoring, engage patients, and enhance overall outcomes. This review seeks to amalgamate existing literature and advancements in telehealth applications specific to hypertension, offering a comprehensive understanding of the present knowledge landscape, identifying gaps, and shedding light on implications for patient outcomes. Telehealth stands as a revolutionary force in hypertension management, providing inventive approaches for remote monitoring, promoting medication adherence, and overall enhancing patient well-being. However, challenges like technological barriers, security concerns, and resistance to change need addressing. Issues surrounding device compatibility, accuracy variations, and limitations in substituting certain in-person examinations also require attention. A holistic strategy, encompassing technological progress, education, and policy evolution, is crucial to overcome these challenges and fully realize telehealth's potential in hypertension management, contributing to improved patient outcomes and a reduced global burden of hypertension and chronic diseases.

Implementation of a Teleophthalmology Screening Program for Diabetic Retinopathy in New York City.

Purpose: To examine the implementation of a teleophthalmology program for diabetic retinopathy (DR) screening at a metropolitan hospital system and identify the challenges that the clinical teams encountered using the program. Methods: The study was conducted in 2 parts. The first was a pilot retrospective chart review of 300 consecutive patients screened for DR by the teleophthalmology screening program. The baseline variables, DR capture rate and staging, and continuity of care for those diagnosed with DR were analyzed. The second was a web-based survey identifying the barriers encountered by 36 physicians and clinical staff as they participated in the teleophthalmology screening program. Results: Part 1: Of the patients evaluated, 57 (19.0%) were diagnosed with DR; 42 (73.7%) had mild nonproliferative DR (NPDR), 7 (12.3%) had moderate NPDR, none had severe NPDR, and 8 (14.0%) had PDR. Thirty-one patients (54.4%) with retinopathy diagnoses were referred for an in-person follow-up at the clinic while the rest continued monitoring via the program. Of this subset, 22 (71.0%) completed the follow-up visit. Part 2: The survey respondents comprised 28 physicians (77.8%), 6 licensed nurse practitioners (16.7%), and 2 medical assistants (5.6%). Twenty-two providers (71.0%) preferred initiating referrals for in-person annual examinations over teleophthalmology screening referrals. The most common barriers described were related to workflow interruption, time constraints, and staff shortages. Conclusions: The teleophthalmology DR screening program allowed identification of early or absent DR at clinics in an urban setting (New York City). The findings suggest areas for targeted improvement in the screening program to better complement internal referral practices' workflows.

Is Digital Video Recorded Simulated Suture Skills Testing Associated With Lower Stress and Anxiety Than Traditional In-Person Assessment for Veterinary Students?

Anxiety can affect exam performance so exploring methods to improve mental health and academic performance is relevant. The objectives of this study were to investigate stress amongst veterinary students undergoing simulated suture skills examinations and determine if digital video recording can reduce stress compared to in-person examination. Thirty-nine students were prospectively enrolled and randomized to undergo two simulated suture examinations, a session proctored by an in-person examiner or one digitally recorded with no proctor present and then crossed over to the other group. Survey data, modified State-Trait Anxiety Inventory (STAI), salivary cortisol, heart rate (HR) and blood pressures were obtained at baseline, prior to, and post-examinations. STAI scores were significantly higher post- in-person examination compared to pre- in-person examination (p = .0014) for first session. Pre- examination STAI scores were significantly higher for in-person examinations compared to recorded examinations (p = .0312) during the second session. Blood pressure was significantly higher during the first session regardless of examination type (p = .018) and HR was lower at baseline than pre- and post-examination, regardless of exam type (p<.0001). Students reported more stress with in-person examinations (p<.0001) and that if given a choice, they would preferentially opt for recorded examinations (p < .0001). Twenty-eight of 32 students with prior suture skills examination experience reported that the simulated examination was less stressful. STAI scores and self-reported stress levels were significantly lower following recorded exams. Digital video recording of skills testing can reduce perceived stress in veterinary students compared to traditional in-person skills examination.

Evaluation of a telemedicine-enabled universal eye health delivery model in rural southern India.

To evaluate the accuracy of tele-ophthalmic examination (TOE) for common ocular conditions in comparison with the gold-standard in-person examination (IPE) for diagnosis and treatment advice. In a prospective, diagnostic accuracy validation study, we recruited 339 consecutive new patients, aged ≥16 years, visiting a vision centre (VC) associated with Aravind Eye Hospital in south India during January and February, 2020. All participants underwent the TOE, followed by IPE on the same visit. The in-person ophthalmologist was masked to the TOE diagnosis and treatment advice. Data were analysed via the sensitivity specificity of TOE versus the gold-standard IPE. TOE achieved high sensitivity and specificity for identifying normal eyes with 87.4% and 93.5%, respectively. TOE had high sensitivity for cataracts (91.7%), infective conjunctivitis (72.2%), and moderate sensitivity for pterygium (62.5%), DR (57.1%), non-serious injury (41.7%), but low sensitivity for glaucoma (12.5%). TOE had high specificity ranging from 93.5% to 99.8% for all diagnoses. The sensitivity for treatment advice ranged from 58.1% to 77.2% and specificity from 96.9% to 100%. The TOE in VCs has acceptable accuracy to an IPE by an ophthalmologist for correctly identifying and treating major eye ailments. Through providing universal eye care to rural populations, this model may contribute to work toward achieving Universal Health Coverage, which is a linchpin of the health-related U.N. Sustainable Development Goals (SDG).

Remote triage practices in general surgery patients from freestanding emergency departments: A 6-year analysis

BackgroundFreestanding emergency departments have risen in popularity as a means to expand access to care. Although some evaluation of freestanding emergency department utility in specific patient populations exists, management of surgical patients via remote triage and disposition has not been previously described. We report our experience with remote triage to discharge home, level I trauma center, or community hospital admission for general surgery patients who present to an affiliated freestanding emergency department. MethodsA retrospective cohort study of patients presenting to freestanding emergency departments requiring surgical consultation between 2016 and 2021 was conducted. Outcomes included disposition, length of stay, surgical intervention, 30-day mortality, and readmission. Undertriage and overtriage rates were calculated and defined as the following: (1) discharge undertriage—discharge home with 30-day emergency department visit/readmission; 2) transfer undertriage—transfers to community hospital requiring transfer to trauma center; and (3) overtriage—admissions <24 hours without surgery. ResultsOf 1,105 patients, 15% were discharged home, 27% were transferred to trauma centers, and 58% were transferred to community hospitals. Patients admitted to trauma centers were older and had higher acuity pathology, whereas patients admitted to community hospitals had higher operative rates with shorter lengths of stay, operating room time, 30-day readmission, and mortality. Transfer undertriage was 0.9% (n = 6), with only 1 patient requiring transfer from a community hospital to a trauma center for disease acuity. Discharge undertriage was 12% (n = 20) due to worsening or persistent pathology. Overtriage was 5.5% (n = 52), with most having a partial small bowel obstruction or ambiguous diagnostic imaging requiring observation. ConclusionRemote surgery triage at freestanding emergency departments, without an in-person examination, demonstrated both low undertriage and overtriage rates, reflecting appropriate triage practices.

Clinician’s Ability to Identify Non-Melanoma Skin Cancer on 3D-Total Body Photography Sectors that Were Initially Identified during In-Person Skin Examination with Dermoscopy

Introduction: Non-melanoma skin cancer (NMSC) is a cause of significant morbidity and mortality in high-risk individuals. Total body photography (TBP) is currently used to monitor melanocytic lesions in patients with high risk for melanoma. The authors examined if three-dimensional (3D)-TBP could be useful for diagnosis of NMSC. Methods: Patients (n = 129; 52 female, 77 male) with lesions suspicious for NMSC who had not yet had a biopsy underwent clinical examination followed by examination of each lesion with 3D-TBP Vectra^®WB360 (Canfield Scientific, Parsippany, NJ, USA) and dermoscopy. Results: The 129 patients had a total of 182 lesions. Histological examination was performed for 158 lesions; the diagnoses included basal cell carcinoma (BCC; n = 107), squamous cell carcinoma (SCC; n = 27), in-situ SCC (n = 15). Lesions were located in the head/neck region (n = 138), trunk (n = 21), and limbs (n = 23). Of the 182 lesions examined, 12 were not visible on 3D-TBP; reasons for not being visible included location under hair and on septal of nose. Two lesions appeared only as erythema in 3D-TBP but were clearly identifiable on conventional photographs. Sensitivity of 3D-TBP was lower than that of dermoscopy for BCC (73% vs. 79%, p = 0.327), higher for SCC (81% vs. 74%, p = 0.727), and lower for in-situ SCC (0% vs. 33%, p = 125). Specificity of 3D-TBP was lower than that of dermoscopy for BCC (77% vs. 82%, 0.581), lower for SCC (75% vs. 84%, p = 0.063), and higher for in-situ SCC (97% vs. 94%, p = 0.344). Diagnostic accuracy of 3D-TBP was lower than that of dermoscopy for BCC (75% vs. 80%), lower for SCC (76% vs. 82%), and lower for in-situ SCC (88% vs. 89%). Lesion location was not associated with diagnostic confidence in dermoscopy (p = 0.152) or 3D-TBP (p = 0.353). If only lesions with high confidence were included in the calculation, diagnostic accuracy increased for BCC (n = 27; sensitivity 85%, specificity 85%, diagnostic accuracy 85%), SCC (n = 10; sensitivity 90%, specificity 80%, diagnostic accuracy 83%), and for in-situ SCC (n = 2; sensitivity 0%, specificity 100%, diagnostic accuracy 95%). Conclusion: Diagnostic accuracy appears to be slightly lower for 3D-TBP in comparison to dermoscopy. However, there is no statistically significant difference in the sensitivity and specificity of 3D-TBP and dermoscopy for NMSC. Diagnostic accuracy increases, if only lesions with high confidence are included in the calculation. Further studies are necessary to determine if 3D-TBP can improve management of NMSC.

Telehealth improves follow-up and monitoring of age-related macular degeneration during the COVID-19 pandemic.

To prevent vision loss, it is important to monitor patients with age-related macular degeneration (AMD) for the development of choroidal neovascularization. The coronavirus disease 2019 (COVID-19) pandemic caused many patients to miss or delay visits. To offset those gaps in care, providers utilized telehealth (TH) to evaluate patients for symptoms of disease progression and provide health education on the importance of continuous monitoring. This study evaluates the impact of TH encounters on the rate of return for recommended in-person examinations for 1103 patients with non-neovascular (dry) AMD seen in an outpatient ophthalmology clinic in 2019 and due for return evaluation after the outbreak of COVID-19 in 2020. Logistic regression analysis was used to identify demographic, clinical, and sociomedical factors associated with TH utilization and in-person return. 422 patients (38%) utilized TH during the study period. Patients who completed a TH encounter were more likely to return for an in-person examination as compared with those who did not receive TH (OR: 1.8, CI 95%: 1.4-2.3, P < 0.001). Completing a TH visit was associated with the detection of new wet AMD (OR: 3.3, 95% CI 1.04-10.6, P = 0.043), as well as with an earlier return for those patients who were found to have disease progression (62 ± 54days vs. 100 ± 57days, P = 0.049). Completing a TH visit increased the rate at which patients with dry AMD returned for recommended in-person eye examinations. In many cases, this permitted the earlier detection of wet AMD, which is linked with achieving better outcomes.

Augmented otorhinologic evaluation in telemedical visits

PurposeTo determine if an endoscopic otologic and rhinologic examination performed by a patient and interpreted remotely by an otolaryngologist is non-inferior to in-person examination, and to assess the feasibility of this system for telemedical visits. Materials and methodsTwenty healthy subjects performed a self-examination of their ears and nose using a commercially available endoscope under remote guidance by an otolaryngology provider over Zoom. This same provider and another otolaryngologist also performed separate, in-person examinations of each subject and rated their findings. Finally, both providers blindly reviewed a video recording of each virtual exam four weeks later and rated their findings. Subjects were surveyed about their experience. Interrater reliability was calculated using Cohen's kappa coefficients and the ability to detect different anatomic structures and features by in-person vs. virtual examination was compared using Wilcoxon tests and Chi-squared proportion tests. ResultsThe subjects' average age was 30 (SD 11.5) years. Interrater reliability was excellent; kappa coefficients were 0.72 and 0.81 (p < 0.001) for virtual and in-person exams, respectively. Of the 3 anatomic structures within the ear exam, none showed a difference in detectability between virtual and in-person exams. Of the 12 structures in the nasal exam, 3 were better visualized in-person and 9 showed no difference. Subject satisfaction was excellent; the average likelihood of recommending this virtual technology to peers (1–10) was 8.65 (SD 1.4). ConclusionsPatient self-examination of the ears and nose using a portable endoscope may be an effective strategy for obtaining valuable data during telemedical otolaryngology visits.

Gait video-based prediction of unified Parkinson’s disease rating scale score: a retrospective study

BackgroundThe diagnosis of Parkinson’s disease (PD) and evaluation of its symptoms require in-person clinical examination. Remote evaluation of PD symptoms is desirable, especially during a pandemic such as the coronavirus disease 2019 pandemic. One potential method to remotely evaluate PD motor impairments is video-based analysis. In this study, we aimed to assess the feasibility of predicting the Unified Parkinson’s Disease Rating Scale (UPDRS) score from gait videos using a convolutional neural network (CNN) model.MethodsWe retrospectively obtained 737 consecutive gait videos of 74 patients with PD and their corresponding neurologist-rated UPDRS scores. We utilized a CNN model for predicting the total UPDRS part III score and four subscores of axial symptoms (items 27, 28, 29, and 30), bradykinesia (items 23, 24, 25, 26, and 31), rigidity (item 22) and tremor (items 20 and 21). We trained the model on 80% of the gait videos and used 10% of the videos as a validation dataset. We evaluated the predictive performance of the trained model by comparing the model-predicted score with the neurologist-rated score for the remaining 10% of videos (test dataset). We calculated the coefficient of determination (R2) between those scores to evaluate the model’s goodness of fit.ResultsIn the test dataset, the R2 values between the model-predicted and neurologist-rated values for the total UPDRS part III score and subscores of axial symptoms, bradykinesia, rigidity, and tremor were 0.59, 0.77, 0.56, 0.46, and 0.0, respectively. The performance was relatively low for videos from patients with severe symptoms.ConclusionsDespite the low predictive performance of the model for the total UPDRS part III score, it demonstrated relatively high performance in predicting subscores of axial symptoms. The model approximately predicted the total UPDRS part III scores of patients with moderate symptoms, but the performance was low for patients with severe symptoms owing to limited data. A larger dataset is needed to improve the model’s performance in clinical settings.

Evaluation of Virtual Prenatal Care for Obstetric Care Delivery During the COVID-19 Pandemic: A Mixed Method Research Study Using the Consolidated Framework in Implementation Research.

Coronavirus 2 (SARS-CoV-2), a novel respiratory virus, rapidly spread, and placed patients at increased risk for short and potentially long-standing medical illnesses. The pandemic necessitated the rapid implementation of virtual prenatal care via telemedicine in obstetrics to maintain social distancing measures. The aim of this study was to assess and understand the patient perspectives of the rapidly implemented virtual prenatal care via a telemedicine model during the Coronavirus disease 2019 (COVID-19) pandemic utilizing the Consolidated Framework in Implementation Research (CFIR). Following the implementation of virtual prenatal care in March 2020, pregnant patients at a large urban clinic in the southeastern United States completed a 19-question anonymous survey that included open and closed-ended questions on their experience receiving virtual prenatal care via telemedicine or in-person prenatal care from May to December 2020. The survey and mixed-methods data analysis was guided by the CFIR framework. A total of 59 patients completed the survey. One-third (31%, n=18) of the patients found virtual prenatal care to be an acceptable alternative model, and half (53%, n=31) found it acceptable only during a pandemic, preferring to return to in-person visits. Qualitative analysis found that some patients were deterred by limited in-person examinations and uncertainty with the virtual platform, while others appreciated the reduced need for transportation, childcare, and time spent. Most patients found virtual prenatal care to be easy to access and an acceptable alternative during the pandemic; however, most would prefer to return to in-person prenatal care visits. Future comparative research studies should examine how, among others, virtual prenatal care versus in-person prenatal care impacts specific maternal and fetal outcomes.
