RESUMO
Aim: The aim of the study was to present the results and impact of the application of artificial intelligence (AI) in the rapid diagnosis of COVID-19 by telemedicine in public health in Paraguay. Methods: This is a descriptive, multi-centered, observational design feasibility study based on an AI tool for the rapid detection of COVID-19 in chest computed tomography (CT) images of patients with respiratory difficulties attending the country's public hospitals. The patients' digital CT images were transmitted to the AI diagnostic platform, and after a few minutes, radiologists and pneumologists specialized in COVID-19 downloaded the images for evaluation, confirmation of diagnosis, and comparison with the genetic diagnosis (reverse transcription polymerase chain reaction (RT-PCR)). It was also determined the percentage of agreement between two similar AI systems applied in parallel to study the viability of using it as an alternative method of screening patients with COVID-19 through telemedicine. Results: Between March and August 2020, 911 rapid diagnostic tests were carried out on patients with respiratory disorders to rule out COVID-19 in 14 hospitals nationwide. The average age of patients was 50.7 years, 62.6% were male and 37.4% female. Most of the diagnosed respiratory conditions corresponded to the age group of 27-59 years (252 studies), the second most frequent corresponded to the group over 60 years, and the third to the group of 19-26 years. The most frequent findings of the radiologists/pneumologists were severe pneumonia, bilateral pneumonia with pleural effusion, bilateral pulmonary emphysema, diffuse ground glass opacity, hemidiaphragmatic paresis, calcified granuloma in the lower right lobe, bilateral pleural effusion, sequelae of tuberculosis, bilateral emphysema, and fibrotic changes, among others. Overall, an average of 86% agreement and 14% diagnostic discordance was determined between the two AI systems. The sensitivity of the AI system was 93% and the specificity 80% compared with RT-PCR. Conclusion: Paraguay has an AI-based telemedicine screening system for the rapid stratified detection of COVID-19 from chest CT images of patients with respiratory conditions. This application strengthens the integrated network of health services, rationalizing the use of specialized human resources, equipment, and inputs for laboratory diagnosis.
RESUMO
OBJETIVOS: Analizar los acontecimientos adversos (AA) y la supervivencia de las terapias biológicas (TB) en el registro paraguayo-uruguayo de AA, Biobadaguay. MÉTODO: Estudio observacional, prospectivo de duración indeterminada. Se han incluido pacientes al inicio de la TB y controles. Se han registrado variables clínicas, biológicas y relacionadas con el tratamiento. RESULTADOS: Se realizaron 826 registros (650 TB y 176 controles). El 70,9% fueron mujeres y el diagnóstico más frecuente fue la artritis reumatoide (AR) (63,2%). La TB más utilizada fue el adalimumab (56,6%) y la causa más frecuente de interrupción, la ineficacia (42,1%). La incidencia de AA en pacientes con TB fue de 143,9 (128,8-160,8) por 1.000 pacientes/año. En el estudio comparativo de AA en función del diagnóstico, se observó que la artritis idiopática juvenil (AIJ) se asoció a más AA globales (RTI = 2,3; IC 95%: 1,6-3,4; p = 4,27×10−6), mientras que la AR se asoció a un mayor número de AA graves (RTI = 2,20; IC 95%: 1,2-4,1; p = 1,17×10−2). Por otro lado, el tratamiento con tocilizumab se asoció a una mayor tasa de AA (RTI = 2,69; IC 95%: 1,90-3,82; p = 3,13×10−8). El diagnóstico de AIJ, el tratamiento con corticoides y el número de TB previas se asociaron a la disminución de la supervivencia de las TB. CONCLUSIÓN: En este primer informe del registro Biobadaguay, la principal causa de interrupción de la TB fue la ineficacia. Con relación al diagnóstico, la AR y la AIJ se asociaron a un mayor riesgo de AA. En este registro, se identificaron variables relacionadas a una menor supervivencia de las TB
OBJECTIVE: Analyze adverse events (AE) and survival associated with biologic therapies (BT) in the Biobadaguay, the Paraguayan Uruguayan registry of adverse events. METHODS: Prospective, observational study of undetermined duration. Patients on BT at initiation and controls were included. Clinical, biological and treatment variables were registered. RESULTS: A total of 826 registers were entered (650 BT and 176 controls); 70.9% were women and rheumatoid arthritis (RA) was the most frequent diagnosis (63.2%). The BT most often used was adalimumab and the main cause of discontinuation was loss of efficacy (42.1%). The incidence of AE of patients on BT was 143.9 (128.8-160.8) per 1000 patients/year. In the comparative study of AE related to diagnosis, juvenile idiopathic arthrosis (JIA) was associated with a higher overall number of AE (RTI = 2.3; 95%CI: 1.6-3.4; P = 4.27 ×10−6), whereas RA was associated with a higher number of serious AE (RTI = 2.2; 95% CI: 1.2-4.1; P =1.17 ×10−2). On the other hand, treatment with tocilizumab was associated with a higher rate of AE (RTI = 2.69; 95% CI: 1.9-3.82; P = 3.13 ×10−8). In JIA, treatment with corticosteroids and number of previous BT was associated with a decrease in BT survival. CONCLUSION: In this first report of the Biobadaguay registry, the main cause of BT discontinuation was loss of efficacy. In terms of the diagnosis involved, RA and JIA were associated with a higher risk of AE. In this registry, variables related to a shorter survival of BT were identified

La aplicación de tecnologías disruptivas en telemedicina facilita la accesibilidad a tecnologías diagnósticas de poblaciones remotas sin acceso a especialistas y mejora la cobertura universal de servicios de salud. Este estudio realizado por la Unidad de Telemedicina del Ministerio de Salud Pública y Bienestar Social (MSPBS) en colaboración con el Dpto. de Ingeniería Biomédica e Imágenes del Instituto de Investigaciones en Ciencias (IICS-UNA) sirvió para evaluar la utilidad de aplicaciones de tecnologías disruptivas en telemedicina para la cobertura universal de servicios de salud. Para el efecto se analizaron los resultados obtenidos por la red de telediagnóstico implementado en 67 hospitales del MSPBS. En dicho sentido se analizaron 540.397 diagnósticos remotos realizados entre enero del 2014 y septiembre de 2019. Del total, el 33,174 % (179.274) correspondieron a estudios de tomografía, 64,825 % (350.313) a electrocardiografía (ECG), 1,997 % (10.791) a electroencefalografía (EEG) y 0,004 % (19) a ecografía. La concordancia entre el diagnostico remoto y el diagnóstico "cara a cara" fue del 95 %. Con el diagnostico remoto se logró una reducción del coste que supone un beneficio importante para cada ciudadano del interior del país. Los resultados obtenidos evidencian que la aplicación de tecnologías disruptivas en telemedicina puede contribuir para la cobertura universal de servicios con tecnologías diagnósticas, maximizando el tiempo y productividad del profesional, aumentando el acceso y la equidad, y disminuyendo los costos. Sin embargo antes de su implementación generalizada se deberá contextualizar con el perfil epidemiológico regional. Palabras claves: tecnología disruptiva, aplicación, tecnología diagnóstica, telemedicina, cobertura universal, servicios de salud, innovación tecnológica.
Introduction: The application of disruptive technologies in telemedicine facilitates accessibility to diagnostic technologies of remote populations without access to specialists and improves universal coverage of health services. This study was carried out by the Telemedicine Unit of the Ministry of Public Health and Social Welfare (MSPBS) in collaboration with the Department of Biomedical Engineering and Imaging of the Institute of Research in Sciences (IICS-UNA). Objective: to evaluate the usefulness of disruptive technology applications in telemedicine for universal coverage of health services January 2014 to September 2019. Material and Method: observational and descriptive design study included 540,397 patients. For this purpose, the results obtained by the telediagnostic network implemented in 67 MSPBS hospitals were analyzed. In this regard, 540,397 remote diagnoses carried out between January 2014 and September 2019 were analysed. Results: of the total, 33.174% (179,274) were CT studies, 64.825% (350,313) electrocardiography (ECG), 1.997% (10,791) electroencephalography (EEG) and 0.004% (19) ultrasound. The concordance between remote diagnosis and "face-to-face" diagnosis was 95%. Conclusion: remote diagnosis achieved a cost reduction that is an important benefit for every citizen of the interior of the country. The results show that the application of disruptive technologies in telemedicine can contribute to the universal coverage of services with diagnostic technologies, maximizing the time and productivity of the professional, increasing access and equity, and lowering costs. However, prior to widespread implementation, the regional epidemiological profile should be contextualized.
