Authors: Prasetyo Simeon Yuda
Published: December 2024

Classification of diseases in potato plants is crucial for agriculture to ensure quality and yield. Potatoes, being staple foods worldwide, are vulnerable to diseases that cause significant production losses. Early and accurate disease identification is essential. This study evaluates the impact of data augmentation on reducing overfitting in deep learning models for potato disease classification. Various CNN architectures, including VGG16, VGG19, Xception, and InceptionV3, were compared in transfer learning and fine-tuning phases. The "Potato Disease Dataset", consisting of 451 images across seven classes, was used. The dataset was split into training, validation, and test sets, and augmentation increased the training set from 360 to 2160 images. The results indicate that models trained with augmented data exhibited improved performance in terms of accuracy, precision, recall, and F1-scores compared to those trained without augmentation. The learning curves show that data augmentation helps in reducing overfitting and enhancing model stability. Data augmentation is crucial for developing robust deep learning models for potato disease classification. Future work will explore advanced augmentation techniques and other architectures to enhance model performance.
Desempenho agronômico e qualitativo de cultivares de cebola sob sistema adensado em função da adubação nitrogenada e potássica
Authors:   , Gonçalves Francisco das Chagas
Published: December 2024

A cebola é uma hortaliça de grande expressão econômica, sendo a terceira em valor econômico no Brasil. Entre os nutrientes mais absorvidos e exportados para os bulbos de cebola, destacam-se o potássio e o nitrogênio. Todavia, as quantidades podem variar com a densidade populacional e com a cultivar utilizada, influenciando diretamente a produtividade e qualidade da cultura. Assim, objetivou-se avaliar o desempenho agronômico e qualitativo de cultivares de cebola sob sistema adensado em função da adubação nitrogenada e potássica. A pesquisa constou de dois experimentos desenvolvidos nos anos 2015 e 2016, em um argissolo da Estação Experimental da UFERSA, município de Mossoró-RN. O delineamento experimental utilizado nos experimentos foi o de blocos casualizados com quatro repetições e os tratamentos foram dispostos em esquema fatorial. Em 2015, empregaram-se duas cultivares (IPA 11 e Rio das Antas) com sete doses de potássio (0, 70, 140, 210, 280, 350 e 420 kg ha-1), ao passo que no ano seguinte utilizaram-se as mesmas cultivares, porém com sete doses de nitrogênio (0, 45, 90, 135, 180, 225 e 270 kg ha-1). As doses de potássio que proporcionaram as máximas produtividades total e comercial foram de 215 e 216 kg ha-1 de K2O, respectivamente. Os sólidos solúveis e o percentual de bulbos das classes 2, 3 e 4 não foram influenciados pela adubação potássica. Houve redução do percentual de bulbos não comerciais com o aumento das doses de potássio. A dose de máxima eficiência econômica foi de 211 kg ha-1 de K2O, responsável por uma produtividade comercial de 61,8 t ha-1. A dose de nitrogênio que proporcionou as maiores produtividades total e comercial foi de 92 kg ha-1 de N. O nitrogênio aumentou os teores de nitrogênio, clorofilas a, b e total nas folhas, os percentuais de bulbos das classes 3 e 4 e a pungência, reduzindo, porém, os percentuais de bulbos das classe 2 e não comerciais. As doses de 108 e 82 kg ha-1 de N proporcionaram as máximas taxas de retorno para IPA 11 (2,07) e Rio das Antas (2,41), respectivamente

Authors:   , Oliveira Herison Alves de
Published: December 2024

A agricultura é uma das principais fontes de renda de assentamentos e comunidades rurais no estado do Rio Grande do Norte, onde a utilização de água é extremamente necessária para viabilizar a produção de hortaliças e frutas. A escassez dos recursos hídricos trazem dezenas de prejuízos à população, inviabilizando a criação de animais, prejudicando o abastecimento de água e dificultando a produção agrícola, principalmente dos pequenos agricultores. O reúso de águas é uma alternativa para minimizar o problema da seca que, além de atender a demanda de água da planta, também fornece nutrientes necessários para o seu desenvolvimento. Objetivou-se com este trabalho avaliar o uso de água cinza tratada sobre o crescimento e teor de nutrientes de mudas de mamoeiros e maracujazeiros. O experimento foi realizado no assentamento rural Jurema, localizado no município de Mossoró-RN. Para cada cultura, foram realizadas as análises não destrutivas: altura, diâmetro do caule e número de folhas, sendo o arranjo experimental em parcelas sub-divididas no tempo, dispostos na parcela três tipos de águas de irrigação: T – Água cinza tratada; A – água de abastecimento e M - mistura do efluente e da água de abastecimento, na proporção 1:1, para cada cultura. Na sub-parcela foram distribuídos os tempos de avaliação 30, 60 e 75 dias após a semeadura, com três blocos e cinco plantas por bloco. Para cada cultura, também foram realizadas as análises destrutivas: comprimento da raiz, massa seca e teor de nutrientes, sendo o arranjo experimental em de blocos casualizados simples, com três tratamentos, correspondentes as águas de irrigação (T, A e M), com três blocos e cinco plantas por bloco. A irrigação com água cinza tratada melhorou a produção de mamoeiros e de maracujazeiro, promovendo maior crescimento e acúmulo de fitomassa em relação à água de abastecimento. Para o mamoeiro, os teores de nitrogênio, potássio, cálcio, magnésio, ferro, manganês e zinco no tecido vegetal não foram alterados pela irrigação com água cinza, enquanto que para o maracujazeiro, os teores de nitrogênio, ferro e zinco são incrementado pela irrigação com água cinza tratada
Manejo da irrigação em cultivares de algodoeiro herbáceo no semiárido brasileiro
Authors:   , Maniçoba Rudah Marques
Published: December 2024

O algodoeiro (Gossypium hirsutum L.) é uma cultura de clima tropical e cultivada na

maioria das regiões de clima quente, apresentando características ideais para a região semiárida

do Nordeste brasileiro. Devido às secas que ocorrem periodicamente nesta região, faz-se

necessário o uso da prática da irrigação para minimizar o efeito do déficit hídrico nesta cultura.

Objetivou-se avaliar os manejos de irrigação, supressões hídricas e déficits hídricos, nas

diferentes fases fenológicas, em cultivares de algodoeiro herbáceo, no semiárido brasileiro, e

seus efeitos sobre os componentes da produção, eficiência hídrica, qualidade da fibra e graus

dias acumulados. Durante dois anos consecutivos foram conduzidos experimentos de campo na

região de Apodi – RN. No ano de 2016, os tratamentos foram constituídos de períodos de

supressão hídrica durante diferentes fases fenológicas (Primeiros botões florais, Inicio do

florescimento, Pico do florescimento e Abertura dos capulhos) e 4 cultivares (BRS 368 RF,

BRS 336, BRS 432 B2RF, BRS 430 B2RF). No segundo ano, em 2017, o experimento foi

dividido entre métodos de manejo de irrigação (Irrigâmetro, Evapotranspiração da cultura e

SmartCrop) e períodos de déficit hídrico (70% e 50% da evapotranspiração da cultura no início

do florescimento e 70% e 50% da evapotranspiração da cultura no pico do florescimento) e 4

cultivares (BRS 433 FL B2RF, BRS JADE, BRS 416 e BRS 430 B2RF). Os experimentos

foram realizados em blocos casualizados, dispostos em faixas, com quatro repetições. Os dados

foram submetidos à análise de variância através do teste F, sendo as médias dos tratamentos

dos fatores comparadas pelo teste de Tukey a 5% de probabilidade. Foram avaliadas a

produtividade de algodão em caroço, a percentagem de fibra, o rendimento de algodão em

pluma, o número de capulhos por planta e a qualidade das fibras do algodoeiro. As variáveis da

fibra analisadas foram: percentagem de fibra, comprimento, uniformidade, índice de fibras

curtas, resistência, alongamento à ruptura, índice micronaire, maturidade, grau de

amarelamento, reflectância e índice de fiabilidade. Os manejos SmartCrop e Evapotranspiração

da cultura proporcionaram os melhores resultados dos componentes de produção e qualidade

de fibra, enquanto o Irrigâmetro resultou na maior eficiência do uso da água. As supressões

hídricas durante a floração resultaram nos menores valores dos componentes de produção. De

forma geral, as supressões hídricas e déficits hídricos aplicados nas diferentes fases fenológicas

das cultivares do algodoeiro herbáceo não resultaram em severas perdas da qualidade da fibra,

pois a fibra produzida está dentro do intervalo de qualidade aceitável pela indústria têxtil

nacional. Os graus dia acumulados variaram em função da supressão hídrica, com as plantas

completando seu ciclo mais precocemente para os tratamentos início do florescimento e pico

do florescimento.

O manejo de primeiros socorros de um dente traumatizado possui influência direta no seu prognóstico. Em alguns casos, quando ele não é realizado já no local do acidente, aumentam muito as chances de o indivíduo perder o dente em um curto prazo de tempo, em virtude da reabsorção radicular. Daí a necessidade de treinar o maior número de pessoas para realizar o manejo emergencial. Material e métodos: Foi desenvolvido um modelo em 3D da arcada superior com um incisivo central removível para a padronização de futuras imagens fotográficas e computadorizadas, no caso de confecção de vídeos educativos. Resultados: O modelo ficou resistente e fácil de ser manejado. Conclusão: O modelo ficou padronizado e apto para ser utilizado em futuras campanhas educacionais de traumatismo dentário.

Published: December 2024

As cerâmicas CAD/CAM têm o objetivo de restabelecer a estrutura dental perdida com maior agilidade. No entanto a diferença cromática entre os diferentes tipos de materiais pode acarretar erros da técnica mesmo após a seleção de cor, por causa da ausência de uma padronização entre as cerâmicas e a sua cor correspondente nas escalas Vita Classical e Vita 3D Master. Objetivo: Quantificar, com o uso do espectrofotômetro, a variação de cor de diferentes cerâmicas CAD/CAM em relação à sua cor correspondente nas escalas Vita Classical e Vita 3D Master. Material e métodos: As cerâmicas feldspáticas (FIA2, FVA2, FIB1) e dissilicato de lítio (DLA1 e DLA2) foram fresadas (n=6) com 2 mm de espessura. As mensurações de cor dos corpos de prova e de suas cores correspondentes na escala Vita Classical e Vita 3D Master foram realizadas com o uso do aparelho espectrofotômetro Vita Easy Shade Advance 4.0 sobre um fundo preto; as variações de cor foram calculadas por meio da fórmula CIEDE2000, considerando os valores de ≥0,81 e ≥1,77 como limites para perceptibilidade e aceitabilidade, respectivamente. Os resultados foram analisados pelos testes Anova/Tukey. Resultados: Em relação à escala Vita Classical, todos os materiais avaliados apresentaram uma variação de cor perceptível e apenas a cerâmica FIB1 evidenciou uma variação de cor clinicamente aceitável. Em relação à escala Vita 3D Master, todas as amostras tiveram uma variação de cor superior considerada clinicamente inaceitável. Conclusão: De modo geral, os materiais restauradores indiretos avaliados apresentaram incompatibilidade com as suas cores correspondentes nas escalas Vita Classical e Vita 3D Master.

A polimerização dos cimentos é fundamental para o sucesso do tratamento. Objetivo: Avaliar a redução na transmissão da luz emitida por dois diferentes aparelhos fotopolimerizadores (Radii-cal e Emitter.B) ao atravessar discos cerâmicos de dissilicato de lítio (Rosetta SP) com diferentes cores (W1LT; W1HT; W2LT; W2HT; W3LT e W3HT) e espessuras (0,5 mm; 1,0 mm e 1,5 mm). Material e métodos: Pelo método da injeção a vácuo foram obtidos discos cerâmicos, que eram colocados entre a ponteira emissora de luz do aparelho fotopolimerizador e o radiômetro que fazia a leitura dos valores de densidade de potência emitida. Os dados foram analisados estatisticamente usando o teste de Kruskal-Wallis (α = 5%), seguido pelo teste Dwass-Steel-Chritchlow-Fligner. Resultados: Os valores de potência do Emitter.B foram estatisticamente superiores aos do Radii em todas as condições. Nos espécimes mais delgados, os valores de irradiância foram estatisticamente superiores em relação aos mais espessos. Não foi encontrada influência da cor ou translucidez da cerâmica sobre os valores de irradiância dos aparelhos. Conclusão: De acordo com os aspectos estudados, a transmissão da luz através do dissilicato de lítio é afetada pela potência do aparelho fotopolimerizador e pela espessura da peça cerâmica, mas não pela cor ou translucidez.

Published: December 2024

New orthodontic bracket designs have been regularly developed. Their clinical performance depends on reliability of measures, among other factors. Objective: The aim of this study was to evaluate slot measures and torque angle of different passive self-ligating metal brackets, while comparing them with measures provided by manufacturers. Material and methods: Five different passive self-ligating metal bracket brands were selected (n = 10 each): Tellus EX, Tellus EX New, Damon Q, Easy Clip and ID-Logical. Bracket slots images were obtained with the aid of Starrett, MV300 Galileo Vision System. For slot digital measurement, Software M3 Metrology Reabout IV was used. Slot measures were evaluated in cervico-occlusal direction (slot height), buccolingual depth (in-out), and bottom-slot inclination (torque angle). Difference between obtained and provided measures was estimated and expressed as a percentage. Data were subjected to descriptive statistical analysis. Results: Most brackets evaluated by the present study revealed variation in both torque angle and slot measures which were confirmed to be greater than those provided by the manufacturer (Easy Clip, Damon Q and Tellus EX), except for two brackets (Tellus EX New and ID-Logical). The latter presented variation within normality with values accepted by ISO standards (± 1 degree and ± 1 mm variation). Conclusion: Most brackets assessed herein (Easy Clip, Damon Q and Tellus EX) presented variation in torque angle and slot measures. Tellus EX New and ID-Logical brackets remained within standards. Better standardization and control should be assumed by manufacturers in order to promote more reliability and predictability of the orthodontic treatment results.

Preventive dentistry has undergone significant advancements in recent years, leading to a shift in the causes of tooth loss. In contrast, dental injury has emerged as the leading cause. Objective: This study presents a case involving multiple dental injuries at the permanent maxillary left central incisor (21) during a 27-year follow-up. Case report: An 18-year-old male patient suffered a dental injury that resulted in a root fracture and avulsion of 21. Tooth replantation was performed 90 minutes after the accident. After 30 days, the endodontic treatment was performed. Thirteen years later, the patient presented to the dental office with a complaint of pain after internal and external dental bleaching. Radiographic signs of root resorption were observed. Endodontic retreatment was then carried out. Twenty-three years from the first trauma, the same tooth suffered a lateral luxation. Twenty-seven years after tooth replantation and four years after stabilization due to lateral luxation, 21 suffered a cervical horizontal root fracture. Thus, extraction was performed. Conclusion: This case report’s singularity is the long follow-up time associated with the sequence of events, including different types of dental injuries and bleaching. In addition, sharing treatment strategies can suggest insights for future studies and help other professionals with similar situations.

Published: December 2024

Introduction

Considering the influence of the shrinkage and creep of high-strength concrete on the vertical deformation and stress of structures, the mechanical behaviour during the construction of the giant column frame-core tube-extension arm truss structure system was simulated by using finite element analysis software.

Methods

For the engineering example of the Wuhan Center, and the safety of the construction channel under a moving load was analysed numerically. The results indicated that that there was a difference in deformation between the elevation position and design position of floor; the maximum deformation difference occurred in the middle of the tower.

Results

Under moving loads, the displacement and stress of the channel were 0.5 times that under full load.

Conclusion

As the load moved, the maximum displacement and stress of steel beam and plate changed, while the displacement and stress of the supports and the placed beam and plate remained unchanged and maintained the minimum value.

Thailand is facing a rapidly aging population, presenting numerous social challenges for the elderly that necessitate effective coping mechanisms to sustain their well-being. This study investigates factors influencing their ability to cope with aging-related challenges and the mechanisms driving their adaptation. A total of 330 participants aged 60 years and older were surveyed. Data analysis involved descriptive statistics, confirmatory factor analysis, structural equation modeling with AMOS, and path analysis. Qualitative data were collected through in-depth interviews and focus group discussions, with participants divided into three age groups: 60-69, 70-79, and 80+. Content analysis was applied to the qualitative data. Findings revealed that cooperation and societal support had the highest factor loading (0.809), while technological proficiency had the lowest (0.513). The structural equation model showed a high coefficient of determination (R² = 85%) for adaptation. The results underscore that adaptability is a key factor in coping with aging challenges, enabling physical and mental adjustment. Enhancing technological skills and promoting government policies and sector collaboration are vital for improving quality of life and readiness to address Thailand’s transition to a super-aged society.

Cerebrovascular diseases (CVDs) are a major and potentially increasing burden to public health. Digital health interventions (DHIs) could support access to and provision of high-quality health care (eg, outcomes, safety, and satisfaction), but the design and development of digital solutions and technologies lack the assessment of user needs. Research is needed to identify opportunities to address health system challenges and improve CVD care with primary users of services as the key informants of everyday requirements.

Objective

This study aims to identify opportunities for DHIs from clients’ and health care professionals’ perspectives to address health system challenges and improve CVD care.

Methods

This study used a qualitative, descriptive approach. Semistructured, in-person interviews were conducted with 22 clients and 26 health care professionals in a single tertiary-level hospital in Finland between August 2021 and March 2022. The data were analyzed using a deductive and inductive content analysis.

Results

Identified opportunities for DHIs in CVD care were organized according to clients, health care professionals, and data services and classified into 14 main categories and 27 generic categories, with 126 subcategories of requirements. DHIs for clients could support the long-term management of health and life changes brought on by CVD. They could provide access to personal health data and offer health information, support, and communication possibilities for clients and their caregivers. Health care professionals would benefit from access to relevant patient data, along with systems and tools that support competence and decision-making. Intersectoral and professional collaboration could be promoted with digital platforms and care pathways. DHIs for data services could enhance care planning and coordination with novel predictive data and interoperable systems for data exchange.

Conclusions

The combined study of client and health care professional perspectives identified several opportunities and requirements for DHIs that related to the information, availability, quality, acceptability, utilization, efficiency, and accountability challenges of health systems. These findings provide valuable social insights into digital transformation and the emerging design, development, and use of user-centered technologies and applications to address challenges and improve CVD care and health care.

Published: December 2024

Background

As the vaccination campaign against COVID-19 progresses, it becomes crucial to comprehend the lasting effects of vaccination on safeguarding against new infections or reinfections.

Objective

This study aimed to assess the risk of new SARS-CoV-2 infections based on the number of vaccine doses, prior infections, and other clinical characteristics.

Methods

We defined a cohort of 800 health care workers in a 24-month study (March 2020 to December 2022) in northern Barcelona to determine new infections by SARS-CoV-2. We used extended Cox models, specifically Andersen-Gill (AG) and Prentice-Williams-Peterson, and we examined the risk of new infections. The AG model incorporated variables such as sex, age, job title, number of chronic conditions, vaccine doses, and prior infections. Additionally, 2 Prentice-Williams-Peterson models were adjusted, one for those individuals with no or 1 infection and another for those with 2 or 3 infections, both with the same covariates as the AG model.

Results

The 800 participants (n=605, 75.6% women) received 1, 2, 3, and 4 doses of the vaccine. Compared to those who were unvaccinated, the number of vaccine doses significantly reduced (P<.001) the risk of infection by 66%, 81%, 89%, and 99%, respectively. Unit increase in the number of prior infections reduced the risk of infection by 75% (P<.001). When separating individuals by number of previous infections, risk was significantly reduced for those with no or 1 infection by 61% (P=.02), and by 88%, 93%, and 99% (P<.001) with 1, 2, 3, or 4 doses, respectively. In contrast, for those with 2 or 3 previous infections, the reduction was only significant with the fourth dose, at 98% (P<.001). The number of chronic diseases only increased the risk by 28%‐31% (P<.001) for individuals with 0‐1 previous infections.

Conclusions

The study suggests that both prior infections and vaccination status significantly contribute to SARS-CoV-2 immunity, supporting vaccine effectiveness in reducing risk of reinfection for up to 24 months after follow-up from the onset of the pandemic. These insights contribute to our understanding of long-term immunity dynamics and inform strategies for mitigating the impact of COVID-19.

Background

Obtaining and describing semiology efficiently and classifying seizure types correctly are crucial for the diagnosis and treatment of epilepsy. Nevertheless, there exists an inadequacy in related informatics resources and decision support tools.

Objective

We developed a symptom entity extraction tool and an epilepsy semiology ontology (ESO) and used machine learning to achieve an automated binary classification of epilepsy in this study.

Methods

Using present history data of electronic health records from the Southwest Epilepsy Center in China, we constructed an ESO and a symptom-entity extraction tool to extract seizure duration, seizure symptoms, and seizure frequency from the unstructured text by combining manual annotation with natural language processing techniques. In addition, we achieved automatic classification of patients in the study cohort with high accuracy based on the extracted seizure feature data using multiple machine learning methods.

Results

Data included present history from 10,925 cases between 2010 and 2020. Six annotators labeled a total of 2500 texts to obtain 5844 words of semiology and construct an ESO with 702 terms. Based on the ontology, the extraction tool achieved an accuracy rate of 85% in symptom extraction. Furthermore, we trained a stacking ensemble learning model combining XGBoost and random forest with an F1-score of 75.03%. The random forest model had the highest area under the curve (0.985).

Conclusions

This work demonstrated the feasibility of natural language processing–assisted structural extraction of epilepsy medical record texts and downstream tasks, providing open ontology resources for subsequent related work.
A Cross-Disciplinary Analysis of the Complexities of Scaling Up eHealth Innovation (Preprint)

UNSTRUCTURED

Innovative eHealth technologies are becoming increasingly common worldwide, with researchers and policy makers advocating their scale-up within and across health care systems. However, examples of successful scale-up remain extremely rare. Although this issue is widely acknowledged, there is still only a limited understanding of why scaling up eHealth technologies is so challenging. This article aims to contribute to a better understanding of the complexities innovators encounter when attempting to scale up eHealth technologies and their strategies for addressing these complexities. We draw on different theoretical perspectives as well as the findings of an interview-based case study of a prominent remote patient monitoring (RPM) innovation in the Netherlands. Specifically, we create a cross-disciplinary theoretical framework bringing together 3 perspectives on scale-up: a structural perspective (focusing on structural barriers and facilitators), an ecological perspective (focusing on local complexities), and a critical perspective (focusing on mutual adaptation between innovation and setting). We then mobilize these perspectives to analyze how various stakeholders (n=14) experienced efforts to scale up RPM technology. We provide 2 key insights: (1) the complexities and strategies associated with local eHealth scale-up are disconnected from those that actors encounter at a broader level scale-up, and this translates into a simultaneous need for stability and malleability, which catches stakeholders in an impasse, and (2) pre-existing circumstances and associated path dependencies shape the complexities of the local context and facilitate or constrain opportunities for the scale-up of eHealth innovation. The 3 theoretical perspectives used in this article, with their diverging assumptions about innovation scale-up, should be viewed as complementary and highlight different aspects of the complexities perceived as playing an important role. Using these perspectives, we conclude that the level at which scale-up is envisaged and the pre-existing local circumstances (2 factors whose importance is often neglected) contribute to an impasse in the scale-up of eHealth innovation at the broader level of scale.

Published: December 2024

BACKGROUND

The shift to video care during the COVID-pandemic exacerbated disparities in health care access, especially among high-need, high-risk (HNHR) adults.

OBJECTIVE

Our objective was to quantify the ability of HNHR older Veterans to use video-visits for healthcare, and identify factors associated with successful video-visit completion.
Setting: A VA Frailty Intervention and Treatment (FIT) clinic, that switched to virtual visits during the pandemic.
Participants: Patients with scheduled clinic visits from April to Oct 2020.

METHODS

Veterans in the FIT clinic underwent a physical, functional, psychological, social, and technology assessment. We sorted patients into four groups: video-visit, telephone-visit, declined, and not reached. We performed appropriate tests to identify factors associated with completing video- vs telephone-visits.

RESULTS

We contacted 110 FIT clinic Veterans. They were 73.5  5.6 years old on average, 46 (41.8%) were White, 46 (41.8%) Black, and 17 (15.5%) Hispanic; Sixty-seven (60.9%) had at least some college education, and 49 (44.5%) were very confident filling out medical forms.
Of the 65 patients who agreed to a virtual visit, 19 (29.2%) patients completed a video-visit successfully, while 37 (57%) completed a telephone-visit; 19/25 (76%) of those who scheduled a video-visit completed it successfully.
In a four-way comparison of Veterans who (1) completed video-visit, (2) completed telephone-visit, (3) reached but no visit, and (4) unable to contact, Veterans who completed a video-visit were the most likely to have access to high speed interet (P=.01), use email (P=.02), be enrolled in My HealtheVet (P=.01), and were less likely to have issues with walking stepping or balance (P=.03), have a better self-perception of aging (P=.04), and more likely to have caregivers (P=.02).
Veterans who completed a video-visit, compared to the telephone-visit group, were more likely to have access to a computer with a camera and microphone (P=.001) and high speed internet/data plan (P=.03), use e-mail (P=.02), and be confident in internet use (P=.05). They were more likely to have a higher health literacy score (P=.04) and be cognitively intact with a MoCA score of ≥26 (P=.02), and were less likely to have issues with walking, stepping and balance (P=.03).

CONCLUSIONS

: Our study found that competing a video-visit requires technology access, ability, and willingness. Among HNHR older Veterans, only a quarter completed a video-visit, and comprised patients who already had access to video-capable technology, used it, and were comfortable with it, and were more likely to have caregivers. Patients who used video-visits were more likely to be physically and cognitively intact than those who used telephone visits. Strategies to expand the use of video-visits into the care of older adults should increase access to and simplify home telehealth technology and leverage caregivers.
