Could Teledentistry Be a Solution in the Diagnosis of Oral Lesions?

In recent years, teledentistry has gained visibility, especially because of the COVID-19 pandemic. Concerning oral medicine, there is great expectation, particularly about its potential to promote early diagnosis of oral lesions. In southern Brazil, two initiatives have shown a positive influence on each other and have led to greater awareness of oral cancer and more access to qualified advice on diagnosing and managing oral lesions. Although the contributions of this approach are promising, there are barriers to be overcome.

Reasons for Provider-to-Provider Synchronous Teleconsultations Between Nurses in Primary Care: A Cross-Sectional Study of TelessaúdeRS-UFRGS Service.

Introduction: Nurses have proven to be fundamental for the expansion and consolidation of primary health care (PHC), as well as the development of digital health strategies. We explored the results of a synchronous telephone teleconsultations service between professionals for nurses in Brazil. Methods: This is a cross-sectional study. We retrieved data from teleconsultations registry. All teleconsultations answered by the team of nurses between September 2018 and July 2021 were analyzed regarding the reasons (according to International Classification of Primary Care, 2nd edition-ICPC-2) and decisions of the teleconsultation. Results: There were 9,273 phone teleconsultations registered in the period, requested by 3,125 nurses from all states throughout the country, of which 56.9% called once and 15.9% used the teleconsultations at least 4 times. We found 362 different reasons for solicitations, which were classified according to the ICPC-2 chapters. The most frequent codes were respiratory (25.9%), general and unspecified (21.2%), and skin (21.2%), which corresponded to 68% of the total sample. Most teleconsultations (66.9%) had as outcome the maintenance of the case at PHC. Conclusion: Teleconsultations are widely used and address a broad number of situations. This service may improve the quality of Brazilian PHC and promote the development of clinical reasoning and critical thinking by nurses.

An international planetary health for primary care massive open online course.

In this Viewpoint we argue that primary care practitioners should receive professional education in how to directly respond to planetary health challenges. We reflect on the provision of a massive open online course (MOOC) on planetary health for primary care practitioners in the context of existing training programmes. We describe the construction, delivery, and certification of a Global South-originated MOOC and explain aspects of its rhizomatic learning theory. We share baseline information and preliminary findings collected on the initial cohort of participants, including their profiles and previous knowledge about planetary health. We suggest that this MOOC is an appropriate response to planetary health challenges, and argue that cost-free, accredited planetary health education for primary care practitioners should be provided as a public good that also fulfils individual professionals' entitlement to quality education and continuing professional development.

Distance learning course improves primary care dentists' diagnosis and self-efficacy in the management of oral lesions.

Oral cancer represents a public health issue because of its high mortality rate, resulting mainly from diagnostic delays. Insufficient training in oral diagnosis is usually perceived by dentists. Distance learning could be used as an auxiliary tool to bridge that gap. This study evaluated the impact of a distance learning course on oral mucosal lesion diagnosis offered to public healthcare dentists. Participants of an online course answered a pretest/posttest comprising clinical images of 30 clinical cases. Participants were questioned about the diagnosis and informed their decision on the cases (referring the cases to a specialist or managing them themselves), as a parameter of perceived self-efficacy. A total of 442 dentists enrolled in the course. Their pass rate was 97%. Classification of the nature of the lesions, diagnostic hypotheses, sensitivity, and specificity improved by 13.4%, 10.0%, 13.4%, and 6.6%, respectively (p<0.01, Wilcoxon test). Regarding management, there was a 16.6% reduction in the intention to refer cases, while confidence in the diagnosis of benign lesions increased by 40%. A distance learning course may be useful in continuing education actions for primary care dentists, improving their diagnostic abilities and encouraging them in the management of oral lesions. Moreover, this strategy could contribute to disseminating knowledge to remote regions, particularly among primary health care professionals.

[TeleOftalmo: strategy to expand the offer of ophthalmologic telediagnostics for primary healthcare in the Southern Brazil]. / TeleOftalmo: estratégia de ampliação da oferta de telediagnósticos oftalmológicos para a atenção primária à saúde no Sul do Brasil.

The use of teleophthalmology may be a viable strategy to track and to diagnose major eye diseases primary health care patients. This study aimed to describe the performance of 30,315 telediagnoses in ophthalmology in primary care patients and the case management of this service. This is a cross-sectional study to evaluate the telediagnosis performed in patients treated at the eight remote points of the TeleOftalmo project from January 2nd, 2018, to December 31st, 2020. The patients' demographic characteristics, the reasons for referral, the diagnoses made according to age group, and the case management of the telediagnosis were evaluated. Most patients were female (66.1%), adults (70.3%), and referred to telediagnosis mainly due to reduced visual acuity (60.5%). Refractive errors were the most prevalent diagnosis in all age groups. Presbyopia was the most prevalent eye disease in adults (65.4%) and older adults (64%), followed by cataracts (41.3%) and suspected glaucoma (10.6%) in older adults. In total, 30,315 patients underwent telediagnosis, 70.5% had their ocular complaints fully resolved, without the need for referral to an in-person ophthalmologist. Telemedicine can be resolutory for the most prevalent eye diseases in the population, increasing the supply of diagnoses, qualifying and assisting in reducing waiting lines for ophthalmologic care.

Telemedicine Versus Face-to-Face Care in Ophthalmology: Costs and Utility Measures in a Real-World Setting.

OBJECTIVES: Advances in telemedicine offer a unique opportunity to expand access to the health system. Nevertheless, few studies have described the impact of telediagnosis implementation on health and economic outcomes. METHODS: An ophthalmology telediagnosis service (TeleOftalmo) was compared with traditional face-to-face care provided by the Brazilian public health system. For both groups, utility data were collected at 2 time points using the Visual Function Questionnaire-Utility Index instrument from interviews with 536 patients. The cost per patient encounter was analyzed according to the time-driven activity-based costing. Value analyses were conducted to ascertain whether and how telemedicine service has the potential to generate cost savings for the health system. RESULTS: Visual function-related quality of life did not differ significantly between TeleOftalmo and face-to-face care groups. Using the current model, the telemedicine service assisted an average of 1159 patients per month at a median cost per telediagnosis of Int$97 (interquartile range, Int$82-Int$119) versus Int$77 (interquartile range, Int$75-Int$80) for face-to-face care. If the telemedicine service was redesigned, considering the opportunities for improvement identified, it could operate at a cost of Int$53 per telediagnosis (a 31% cost savings) and could serve 3882 patients per month. CONCLUSIONS: This study demonstrates the potential value of a telemedicine service. There was no difference in patient-perceived utility between a telediagnostic ophthalmology service and face-to-face care by an eye specialist. TeleOftalmo has the potential to be a cost-saving strategy for the Brazilian health system and could be a template for implementation of telediagnostic services in other regions.

Oral Medicine Experience and Attitudes Toward Oral Cancer: An Evaluation of Dentists Working in Primary Health Care.

This analytical, cross-sectional, observational study aimed to evaluate the perception of dentists working at the public system of the state of Rio Grande do Sul, southern Brazil, regarding academic training to treat oral lesions, adoption of preventive measures for oral cancer, and attitude toward the need to perform oral biopsies. The sample consisted of questionnaires filled out by 192 dentists (153 women and 39 men) working in primary health care who participated in training activities on oral cancer diagnosis in July 2016. To enroll in the training activities, the professionals completed an online questionnaire to evaluate their perceptions regarding oral cancer issues. With respect to preventive measures, 96.88% of dentists reported performing full mouth examination, 87.50% reported providing tobacco cessation counseling, and 51.04% reported giving advice on excessive alcohol consumption. In addition, 72.40% and 44.79% of dentists considered, respectively, clinical training and theory instruction in oral medicine to be insufficient during undergraduate school. Only 8.33% reported performing biopsies in daily clinical routine, and almost 90% reported referring the patient to a specialist from the public system or universities. Lack of experience was the main reason not to perform a biopsy. The dentists in our sample recognize the importance of preventive measures for oral cancer, but few of them perform biopsies regularly. Therefore, there is a need for continuing education actions including practical training.

The Role of Telehealth in the Covid-19 Pandemic: A Brazilian Experience. / O Papel da Telessaúde na Pandemia Covid-19: Uma Experiência Brasileira.

SARS-CoV-2, the virus that causes Covid-19, is the third coronavirus to cause severe disease in humans and to spread globally in the past two decades. In this context, several national public health departments, including the Brazilian Ministry of Health, highlighted what was, until then, considered a support service to the health system: telehealth and telemedicine. We intend to present the actions carried out by a national telehealth service in Brazil, both as a Primary Health Care (PHC) support service to professionals and to patients, as well as discussing the potential to reorganize a health system. This is a prevalence study that summarizes the measures adopted by Brazilian Telehealth Center from the 9th to the 27th epidemiological weeks of 2020 to support the health services of the Brazilian Unified Health System (SUS). There was an increase of 76.8% in the demand for telephone teleconsultations during the evaluated period compared to the same period in 2019, with 28.8% of the entire demand arising from doubts related to Covid-19. The Covid-19 pandemic demanded a quick response, with the organization of materials about the disease, a new team to carry out telemonitoring and teleconsultation activities, in addition to the creation of a manual for teleconsultations in Primary Health Care.

The management of COVID-19 cases through telemedicine in Brazil.

In Dec 2020 Brazil became one of the worldwide epicenters of the COVID-19 pandemic with more than 7.2M reported cases. Brazil has a large territory with unequal distribution of healthcare resources including physicians. Resource limitation has been one of the main factors hampering Brazil's response to the COVID-19 crisis. Telemedicine has been an effective approach for COVID-19 management as it allows to reduce the risk of cross-contamination and provides support to remote rural locations. Here we present the analyses of teleconsultations from a countrywide telemedicine service (TelessáudeRS-UFRGS, TRS), that provides physician-to-physician remote support during the COVID-19 pandemic in Brazil. We performed a descriptive analysis of the teleconsultation incoming calls and a text analysis from the call transcripts. Our findings indicate that TRS teleconsultations in Brazil experienced an exponential increment of 802.% during a period of 6 days, after the first death due to COVID-19 was reported. However, the number of teleconsultations cases decreased over time, despite the number of reported COVID-19 cases continuously increasing. The results also showed that physicians in low-income municipalities, based on GDP per capita, are less likely to consult the telemedicine service despite facing higher rates of COVID-19 cases. The text analysis of call transcripts from medical teleconsultations showed that the main concern of physicians were "asymptomatic" patients. We suggest an immediate reinforcement of telehealth services in the regions of lower income as a strategy to support COVID-19 management.

Social Distancing, Mask Use, and Transmission of Severe Acute Respiratory Syndrome Coronavirus 2, Brazil, April-June 2020.

We assessed the associations of social distancing and mask use with symptomatic, laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection in Porto Alegre, Brazil. We conducted a population-based case-control study during April-June 2020. Municipal authorities furnished case-patients, and controls were taken from representative household surveys. In adjusted logistic regression analyses of 271 case-patients and 1,396 controls, those reporting moderate to greatest adherence to social distancing had 59% (odds ratio [OR] 0.41, 95% CI 0.24-0.70) to 75% (OR 0.25, 95% CI 0.15-0.42) lower odds of infection. Lesser out-of-household exposure (vs. going out every day all day) reduced odds from 52% (OR 0.48, 95% CI 0.29-0.77) to 75% (OR 0.25, 95% CI 0.18-0.36). Mask use reduced odds of infection by 87% (OR 0.13, 95% CI 0.04-0.36). In conclusion, social distancing and mask use while outside the house provided major protection against symptomatic infection.

Ophthalmic image acquired by ophthalmologists and by allied health personnel as part of a telemedicine strategy: a comparative study of image quality.

OBJECTIVES: This study evaluates the quality of ophthalmic images acquired by a nurse technician trained in teleophthalmology as compared with images acquired by an ophthalmologist, in order to provide a better understanding of the workforce necessary to operate remote care programs. METHODS: A cross-sectional study was performed on 2044 images obtained from 118 participants of the TeleOftalmo project, in Brazil. Fundus and slit-lamp photography were performed on site by an ophthalmologist and by a nurse technician under the supervision of a remote ophthalmologist. Image quality was then evaluated by masked ophthalmologists. Proportion of suitable images in each group was compared. RESULTS: The proportion of concordant classification regarding quality was 94.8%, with a corrected kappa agreement of 0.94. When analyzing each type of photo separately, there was no significant difference in the proportion of suitable images between on-site ophthalmologist and nurse technician with remote ophthalmologist assistance for the following: slit-lamp views of the anterior segment and anterior chamber periphery, and fundus photographs centered on the macula and on the optic disc (P = 0.825, P = 0.997, P = 0.194, and P = 0.449, respectively). For slit-lamp views of the lens, the proportion of suitable images was higher among those obtained by an ophthalmologist (99.6%) than by a technician (93.8%, P < 0.01). CONCLUSIONS: Ophthalmic photographs acquired by a trained technician consistently achieved >90% adequacy for remote reading. Compared with ophthalmologist-acquired photos, the proportion of images deemed suitable achieved a high overall agreement. These findings provide favorable evidence of the adequacy of teleophthalmological imaging by nurse technicians.

Teledentistry in the diagnosis of oral lesions: A systematic review of the literature.

OBJECTIVE: The purpose of this systematic review is to summarize information on the use of teledentistry in the diagnosis of oral lesions. MATERIALS AND METHODS: A systematic literature search conducted in August 2018 included articles published until December 2018 in 4 databases. Two reviewers evaluated the search results separately. If they were uncertain as to whether to include an article, a third reviewer made the final decision. Studies related to the diagnosis of oral lesions using teledentistry were included. The methodological quality of the studies was analyzed using the Quality Assessment of Studies of Diagnostic Accuracy. RESULTS: Eleven articles were included in the study. The selected articles were published between 1999 and 2018, predominantly in developing countries. The professionals acting as patient examiners are dental students and dentists, as well as other health professionals. Most of the patients evaluated in the studies were from rural populations or locations distant from large centers. The tools used to obtain patient data were smartphones, videoconference, email, questionnaires, histopathological exams, and telemedicine applications and systems. Most studies concluded that there is a high level of agreement between teledentistry and clinical consultation and that the use of this resource for diagnostic purposes can reduce costs and the travel time to consult a specialist personally. Nine of the 11 studies were of good quality. CONCLUSIONS: Teledentistry has the potential to improve the care quality related to diagnosis and management of oral lesions, shortening distances between patients who need specialized diagnoses and specialists.

Perceived usability of a store and forward telehealth platform for diagnosis and management of oral mucosal lesions: A cross-sectional study.

EstomatoNet was created in the south of Brazil to provides specialist support over a web-based platform to primary care dentists for diagnosis of oral lesions. To evaluate the usability of EstomatoNet and to identify user perceptions regarding their expectations and difficulties with the system; and to compare the perceptions of regular users of the service to those of first-time users. Sixteen dentists were selected for the study: 8 were frequent users of EstomatoNet and 8 were residents who had never used the Platform. To assess usability, participants were required to request telediagnosis support for a fictional case provided by the research team. During the process of uploading the information and sending the request, users were asked to "think out loud," expressing their perceptions. The session was observed by an examiner with remote access to the user's screen (via Skype). After the simulation, users completed the System Usability Scale (SyUS), a validated tool with scores ranging from 0 to 100. The mean SyUS score assigned by frequent users was 84.7±6.6, vs. 82.2±9.3 for residents (satisfactory usability: score above 68). The difference between the groups was not statistically significant (Student t test, P = .55). The residents group took longer (347.1±101.1s) to complete the task than frequent users (252.8±80.3s); however, the difference between the groups was not statistically significant (Student t test, P = .06). In their subjective evaluation, users suggested the inclusion of a field to add further information on outcomes and resolution of the case and changes in the position of the "Send" button to improve workflow. The present results indicate satisfactory usability of EstomatoNet. The Platform seems to meet the needs of users regardless of how experienced they are; nevertheless, a few minor changes in some steps would improve the tool.

Access and regulation of specialized care in Rio Grande do Sul: the RegulaSUS strategy of TelessaúdeRS-UFRGS. / Acesso e regulação ao cuidado especializado no Rio Grande do Sul: a estratégia RegulaSUS do TelessaúdeRS-UFRGS.

In Primary Health Care (PHC), access, and integrality are strongly influenced by the coordination of care, which in turn receives a positive impact from the articulation of telehealth actions for teleregulation of care. We created a teleregulation method (RegulaSUS Project) based on specific protocols firmly grounded in scientific evidence. From data of the regulatory system and TelessaúdeRS, we explored the effects of RegulaSUS on PHC and access to specialized care. This method set comprehensive protocols, with a significant mean reduction of 30% in the specialized visits queue over 360 days. It reduced waiting time for medical clinical visits (median of 66 days) but not for surgical appointments. Waiting times for queued cases varied inversely, increasing for clinical and declining for surgical specialties. The use of teleconsultations unrelated to regulation increased with the exposure of professionals to RegulaSUS. The intervention evidence potentiality in the integration of health systems, mainly among low- and middle-income countries, and makes telehealth act as a meta-service, building efficient, qualified, and equitable networks.

Na Atenção Primária à Saúde (APS) acesso e integralidade são fortemente influenciados pela coordenação do cuidado, que por sua vez recebe impacto positivo da articulação de ações de telessaúde para a telerregulação da assistência. Criamos uma metodologia de telerregulação (Projeto RegulaSUS) baseada em protocolos específicos firmemente alicerçados em evidências. A partir de dados do sistema de regulação e do TelessaúdeRS exploramos os efeitos do RegulaSUS na APS e no acesso ao cuidado especializado. A metodologia foi capaz de criar protocolos abrangentes, com expressiva redução média da fila de consultas especializadas de 30% em 360 dias. Reduziu o tempo de espera na marcação de consultas em especialidades clínicas (mediana de 66 dias), mas não em cirúrgicas. Tempos de espera nos casos mantidos em fila variaram de forma inversa, aumentado em especialidades clínicas e diminuindo em cirúrgicas. O uso de teleconsultorias espontâneas aumentou com a exposição dos profissionais ao RegulaSUS. A intervenção tem potencial na integração de sistemas de saúde, principalmente em países de baixa e média renda, e faz com que a telessaúde atue como metasserviço, construindo redes eficientes, qualificadas e equânimes.

The use of telemedicine to support Brazilian primary care physicians in managing eye conditions: The TeleOftalmo Project.

PURPOSE: To determine whether teleophthalmology can help physicians in assessing and managing eye conditions and to ascertain which clinical conditions can be addressed by teleophthalmology in primary care setting. METHODS: We evaluated the resolution capacity of TeleOftalmo, strategy implemented in the public health system of southern Brazil. Resolution capacity was defined as the ability to fully address patients' eye complaints in primary care with remote assistance from ophthalmologists. Data from tele-eye reports were collected over 14 months. Resolution capacity was compared across different age groups and different ocular conditions. RESULTS: Overall, 8,142 patients had a tele-eye report issued in the study period. Resolution capacity was achieved in 5,748 (70.6%) patients. When stratified into age groups, the lowest capacity was 43.1% among subjects aged ≥65 years, while the highest was 89.7% among subjects aged 13-17 years (p<0.001). Refractive error (70.3%) and presbyopia (56.3%) were the most prevalent conditions followed by cataract (12.4%) and suspected glaucoma (7.6%). Resolution capacity was higher in cases of refractive error, presbyopia, spasm of accommodation and lid disorders than in patients diagnosed with other condition (p<0.001). CONCLUSIONS: With telemedicine support, primary care physicians solved over two-thirds of patients' eye or vision complaints. Refractive errors had high case resolution rates, thus having a great impact on reducing the number of referrals to specialty care. Teleophthalmology adoption in primary-care settings as part of the workup of patients with eye or vision complaints promotes a more effective use of specialty centers and will hopefully reduce waiting times for specialty referral.
