Data-driven, cross-disciplinary collaboration: lessons learned at the largest academic health center in Latin America during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency. Methods: At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank. Additionally, a COVID-19 curated collection was created within the institutional digital library of academic papers to map the research output. Results: Over the course of the experience, the possible benefits and challenges of this type of research support approach were identified and discussed, leading to a set of recommended strategies to enhance collaboration within the research institution. Demographic and clinical data from COVID-19 hospitalizations were compiled in a database including adults and a minority of children and adolescents with laboratory confirmed COVID-19, covering 2020-2022, with approximately 350 fields per patient. To date, this database has been used in 16 published studies. Additionally, we assessed 700 adults 6 to 11 months after hospitalization through comprehensive, multidisciplinary in-person evaluations; this database, comprising around 2000 fields per subject, was used in 15 publications. Furthermore, thousands of blood samples collected during the acute phase and follow-up assessments remain stored for future investigations. To date, more than 3,700 aliquots have been used in ongoing research investigating various aspects of COVID-19. Lastly, the mapping of the overall research output revealed that between 2020 and 2022 our academic system produced 1,394 scientific articles on COVID-19. Discussion: Research is a crucial component of an effective epidemic response, and the preparation process should include a well-defined plan for organizing and sharing resources. The initiatives described in the present paper were successful in our aim to foster large-scale research in our institution. Although a single model may not be appropriate for all contexts, cross-disciplinary collaboration and open data sharing should make health research systems more efficient to generate the best evidence.

Telemedicine in Brazil: Teleconsultations at the Largest University Hospital in the Country.

The coronavirus disease (COVID-19) pandemic leveraged telemedicine worldwide mainly due to the need for social distancing, patient safety, and infection prevention. The Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP) was a key reference site in the treatment of COVID-19 severe cases in the country. To continue patient's health care, it became necessary to increase the number of teleconsultations and standardize it institutionally. Herein, we briefly described how the HCFMUSP improved the teleconsultation health care service during the COVID-19 pandemic, highlighting the implementation of important innovations and the throughout standardization process, including patients and professional workflow. We also detailed the methodology used to implement or improve teleconsultation in a medical/multidisciplinary specialty at HCFMUSP. All these efforts made the HCFMUSP reach the goal of converting 15% of all face-to-face consultations into teleconsultations only in 2021. In addition, there were more than 370,000 teleconsultations until the end of 2022. Our experience has shown that having a supporting team, a digital certification process, and the data integration were key factors toward the successful implementation of the teleconsultation services. We believe that progressing toward teleconsultation will improve the population covered by health care services in Brazil, as well as contribute to a reduction of waiting time, and solving costs to health care institutions and patients. We expect this report of our experience in teleconsultation implementation could inspire and guide other health care institutions in the development of telemedicine.

Immunothrombosis and COVID-19 ‒ a nested post-hoc analysis from a 3186 patient cohort in a Latin American public reference hospital.

OBJECTIVE: COVID-19 is associated with an elevated risk of thromboembolism and excess mortality. Difficulties with best anticoagulation practices and their implementation motivated the current analysis of COVID-19 patients who developed Venous Thromboembolism (VTE). METHOD: This is a post-hoc analysis of a COVID-19 cohort, described in an economic study already published. The authors analyzed a subset of patients with confirmed VTE. We described the characteristics of the cohort, such as demographics, clinical status, and laboratory results. We tested differences amid two subgroups of patients, those with VTE or not, with the competitive risk Fine and Gray model. RESULTS: Out of 3186 adult patients with COVID-19, 245 (7.7%) were diagnosed with VTE, 174 (5.4%) of them during admission to the hospital. Four (2.3% of these 174) did not receive prophylactic anticoagulation and 19 (11%) discontinued anticoagulation for at least 3 days, resulting in 170 analyzed. During the first week of hospitalization, the laboratory most altered results were C-reactive protein and D-dimer. Patients with VTE were more critical, had a higher mortality rate, worse SOFA score, and, on average, 50% longer hospital stay. CONCLUSION: Proven VTE incidence in this severe COVID-19 cohort was 7.7%, despite 87% of them complying completely with VTE prophylaxis. The clinician must be aware of the diagnosis of VTE in COVID-19, even in patients receiving proper prophylaxis.

User Experience Regarding Digital Primary Health Care in Santarém, Amazon: Evaluation of Patient Satisfaction and Doctor's Feedback.

BACKGROUND: With the arrival of the pandemic, telemedicine has been widely used to provide medical care and can be used to assist patients in regions far from urban centers that are difficult to access, such as riverside communities in the Brazilian Amazon region. A telemedicine project connecting São Paulo, a mega-metropolis, to Paysandú, a riverside district in the Amazon, was built to serve the local population where access to the nearest medical care is 6 hours away by speedboat. OBJECTIVE: This study aims to assess the feedback from patients and doctors regarding the use of telemedicine in outpatient care at Paysandú, a riverside district in the Amazon. METHODS: This is a single-center study following the guidelines "Evaluating digital health products" from Public Health England, with local adaptations for the project and the Brazilian reality, that was conducted between São Paulo and Santarém in Brazil. A survey was carried out with patients who were treated by a doctor in the city of São Paulo, about 2500 km from the local basic health unit, between September 27 to December 15, 2021. At the end of each teleconsultation, the attending physician answered an administrative survey form, and the patient answered a satisfaction survey. RESULTS: A total of 111 patients completed the satisfaction survey from a total of 220 consultations carried out during the period (95% CI margin error 0.22%). According to the survey, more than 95% of patients were satisfied with the service, 87.4% (n=97) had previous experience with videoconferencing, and 76.6% (n=85) reported that their demand was fully solved. Additionally, according to the hired doctor's feedback, the average duration of the consultations was between 15 and 20 minutes. Of the 220 teleconsultations performed, 90.9% (n=200) of the demands were solved with support from the local health team, and 99.1% (n=218) of the appointments had a problem with audio or video. CONCLUSIONS: This teleconsultation project between São Paulo and Paysandú showed that it is possible to offer medical care from more developed locations to communities far from urban centers, as is the case with Paysandú District. Beyond the feasibility of the infrastructure, acceptance and satisfaction among patients were high. This health care supply model has proven to be functional and should be expanded nationally or perhaps internationally to regions lacking medical assistance. Escalation of the project does not seem too difficult once infrastructure issues are solved.

The Impact of Artificial Intelligence on Waiting Time for Medical Care in an Urgent Care Service for COVID-19: Single-Center Prospective Study.

BACKGROUND: To demonstrate the value of implementation of an artificial intelligence solution in health care service, a winning project of the Massachusetts Institute of Technology Hacking Medicine Brazil competition was implemented in an urgent care service for health care professionals at Hospital das Clínicas of the Faculdade de Medicina da Universidade de São Paulo during the COVID-19 pandemic. OBJECTIVE: The aim of this study was to determine the impact of implementation of the digital solution in the urgent care service, assessing the reduction of nonvalue-added activities and its effect on the nurses' time required for screening and the waiting time for patients to receive medical care. METHODS: This was a single-center, comparative, prospective study designed according to the Public Health England guide "Evaluating Digital Products for Health." A total of 38,042 visits were analyzed over 18 months to determine the impact of implementing the digital solution. Medical care registration, health screening, and waiting time for medical care were compared before and after implementation of the digital solution. RESULTS: The digital solution automated 92% of medical care registrations. The time for health screening increased by approximately 16% during the implementation and in the first 3 months after the implementation. The waiting time for medical care after automation with the digital solution was reduced by approximately 12 minutes compared with that required for visits without automation. The total time savings in the 12 months after implementation was estimated to be 2508 hours. CONCLUSIONS: The digital solution was able to reduce nonvalue-added activities, without a substantial impact on health screening, and further saved waiting time for medical care in an urgent care service in Brazil during the COVID-19 pandemic.

Use and misuse of biomarkers and the role of D-dimer and C-reactive protein in the management of COVID-19: A post-hoc analysis of a prospective cohort study.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

Building an outpatient telemedicine care pilot using Scrum-like framework within a medical residency program.

OBJECTIVES: A good health care does not only depend on good medical practice, but also needs great management of its resources, which are generally short. In this sense, PROAHSA has been training new health managers since 1972. With the arrival of the COVID-19 pandemic, it was clear that medicine will go through a new phase, where telehealth will be present in this "Improved Normal". This report is about how a pilot teleconsultation study was carried out for HCFMUSP patients through the Scrum-like framework. It is to deploy a pilot of remote assistance involving a doctor and a patient in the Ambulatory of Hepatology and Liver Transplantation of HCFMUSP. METHODS: We applied the Scrum-like framework to carry out this work with an interdisciplinary multifunctionality team. RESULTS: A full telemedicine service flow was implemented within eight weeks using existing infrastructure and resources implementing the Scrum methodology. Twenty-three teleconsultations were scheduled and eight guides built. CONCLUSION: Scrum framework has a great potential to improve the training of students and to conclude pilot projects.

Instrumentação de canais artificiais curvos com limas manuais de níquel-titânio profile Series 29 / Instrumentation of simulated curved canals using nickel-titanium profile series 29 hand file

Trinta e seis canais artificiais curvos confeccionados em blocos de resina epóxi transparente foram instrumentados manualmente por limas de níquel-titânio Nitiflex com pontas ISO (Grupo A) e por limas de níquel-titânio Profile Series 29 (grupo B). Com o auxílio de uma plataforma metálica especificamente confeccionada, foi empregada a técnica da dupla exposição radiográfica. As radiografias resultantes foram posiocionadas em um scanner, e as imagens, digitalizadas (40X), visualizadas no monitor de um microcomputador. A aferição de transporte apical foi realizada pelo sofware Digora for Windows 1,51. Os dados obtidos foram avaliados estatisticamente pela análise de variância a um critério (Anova) ao nível de significância de 5 por cento. Não foram observadas diferenças estatisticamente significantes entre os dois grupos experimentais, com relação à intesidade de transporte apical. O tempo médio despendido para instrumetação dos canais do Grupo A foi significativamente menor

Comportamento das limas manuais de aço inoxidável e de níquel-titânio em relaçäo ao transporte / Behaviour of stainless steel and nickel-titanium hand files on apical canal transportation

O objetivo deste trabalho foi comparar a açäo das limas de aço inoxidável e de níquel-titânio com relaçäo à ocorrência de transporte apical em canais mesiais curvos de primeiros molares superiores extraídos, por meio da dupla exposiçäo radiográfica. Os resultados mostraram näo haver diferenças estatísticas significativas entre os dois instrumentos

Maxillary lateral incisor with two root canals: fusion, gemination or dens invaginatus? / Incisivo lateral superior com dois canais radiculares: fusão, geminação ou dens invaginatus?

É descrito o retratamento endodôntico de um incisivo lateral superior com dois canais. O diagnóstico de fusão, geminação ou dens invaginatus não pôde ser precisamente estabelecido, devido a características anatômicas conflitantes e à intervenção endodôntica anterior, que suprimiu a configuração original da câmara pulpar

Anatomia endodôntica incomum: o canal em forma de "C" / Unusual root canal morphology: the C-shaped canal

Os autores relatam o tratamento endodôntico bem sucedido de um segundo molar inferior que apresenta uma variaçäo anatômica relativamente incomum, conhecida como "canal em C"

Avaliaçäo radiográfica do deslocamento apical da obturaçäo de canais radiculares promovido pelo compactador de McSpadden na técnica híbrida de Tagger / Roentgenographic evaluation of the apical displacement of root canal obturation provided by the McSpadden compactor on Tagger's hybrid technique

Vinte dentes unirradiculados extraídos foram instumentados e obturados pela técnica híbrida de Tagger. Foram comparadas as radiografias processadas logo após a condensaçäo lateral do terço apical, com aquelas realizadas depois do emprego dos compactadores de McSpadden. Concluímos que o emprego adequado dos compactadores näo interferiu na obturaçäo do canal em seu terço apical

Selante apical propiciada pela técnica thermal em canais retos e curvos / Apical sealing ability provides by thermal techenique in straight and curved roots canals

Foram utilizadas 40 raízes de dentes molares humanos (superiores e inferiores) extraídos, que foram divididas em dois grupos distintos. O primeiro grupo composto pelas raízes mesiais dos molares inferiores e mesiovestibulares dos superiores, enquanto o segundo grupo foi formado pelas raízes distais dos molares inferiores e palatinas dos superiores. Os canais foram instrumentados e, entäo, obturados pelas técnicas da condensaçäo lateral e Thermafil. Os dentes tiveram suas superfícies externas impermeabilizadas, com exceçäo da porçäo apical, sendo entäo, imersos em tinta da India (nanquim), aplicando-se vácuo por determinado período. Findo o tempo preestabelecido de sua imersäo, as raízes foram lavadas, limpas e secadas, quando entäo sofreram desmineralizaçäo, desidrataçäo e clareaçäo, tornando-se transparentes. Realizaram-se mensuraçöes das infiltraçöes lineares, e os dados obtidos foram avaliados, tabulados e submetidos à análise estatística. Pôde-se entäo concluir que: em relaçäo à capacidade seladora, näo houve diferença estatística entre as técnicas de condensaçäo lateral e do Thermafil; em canais curvos e atrésicos (mesiovestibulares de molares superiores e mesiais de molares inferiores) houve maior infiltraçäo do que nos canais amplos e retos (distais de molares inferiores e palatinos de molares superiores)
