Objetivo. Determinar la viabilidad y puesta en marcha de un sistema de telediagnóstico para dar asistencia sanitaria a poblaciones remotas y dispersas del Paraguay. Métodos. El estudio fue realizado en todos los hospitales regionales, generales y principales hospitales distritales de las 18 regiones sanitarias del Paraguay. En el sistema se registraron los datos clínicos y las imágenes tomográficas, ecográficas y trazados electrocardiográficos del paciente que precisaba de un diagnóstico por parte de un médico especialista. Esta información se transmitió a los especialistas en imagenología y en cardiología para su diagnóstico remoto y posterior envío del informe a los hospitales conectados al sistema. Se analizó el costo-beneficio e impacto de la herramienta de telediagnóstico desde la perspectiva del Sistema Nacional de Salud. Resultados. Entre enero de 2014 y mayo de 2015 se realizaron 34 096 telediagnósticos distribuidos en 25 hospitales a través del Sistema de Telemedicina del Ministerio de Salud. El costo unitario promedio del diagnóstico remoto fue de USD 2,6 (dólares estadounidenses) para electrocardiograma (ECG), tomografía y ecografía, mientras que el costo unitario para el diagnóstico “cara a cara” fue de UDS 11,8 para ECG; USD 68,6 para tomografía y USD 21,5 para ecografía. La reducción del costo mediante el diagnóstico remoto fue de 4,5 veces para ECG; 26,4 veces para tomografía y de 8,3 veces para ecografía. En términos monetarios, la implementación del sistema de telediagnóstico, durante los 16 meses del estudio, significó un ahorro promedio de USD 2 420 037. Conclusión. Paraguay cuenta con un sistema de telediagnóstico para electrocardiografía, tomografía y ecografía aplicando las tecnologías de la información y comunicación (TIC) de bajo costo, basadas en software libre y escalable a otros tipos de estudios diagnósticos a distancia; de interés para la salud pública. Con una aplicación práctica del telediagnóstico, se contribuyó al fortalecimiento de la red integrada de servicios y programas de salud, lo que permitió maximizar el tiempo del profesional y su productividad, mejorar la calidad, aumentar el acceso y la equidad, y disminuir los costos.
Entendemos a la Telemedicina como un sistema de prestación de servicios que tiene como objetivo principal apoyar a la medicina por medio de la tecnología. En el Paraguay existen áreas rurales o remotas de difícil acceso en donde no llegan los servicios especializados que muchas veces son necesarios en esas comunidades, la Telemedicina se convirtió en una herramienta muy eficaz para dar una solución confiable, eficaz y barata.

Introduction: Information and communication technologies (ICTs) applied to the healthcare offer multiple advantages for diagnostic services and remote consultations. However, evidence on the diagnosis improvement in rural communities is limited. The usability of telemedicine to improve the coverage of diagnostic services in Paraguay was investigated. Methods: The goal of this descriptive study was to evaluate whether a telemedicine system implemented in remote public regional and district hospitals in Paraguay over a period of 3 years from 2014 to 2016 could facilitate the universal coverage of diagnostic services in rural communities. Results: In the study period, 182,406 remote diagnoses from 54 hospitals through a telemedicine system were performed. Of the total, 37.31% (68,085) corresponded to tomography, 62.00% (113,059) to electrocardiogram (ECG), 0.68% (1243) to electroencephalogram (EEG), and 0.01% (19) to ultrasound (US). Tomography was performed in 12 hospitals: 54.4% corresponded to head injuries, 13.8% to chest, and the rest to other anatomical regions. ECG was carried out in 52 hospitals; and in 62.1% of the cases, the results were normal; 12.5% unspecified arrhythmias; and 10.4% sinus bradycardia among the most frequent pathologies. EEG diagnosis showed history of seizure (54.3%), evolutionary control (14.0%), and headache (11.5%) among the most frequent diagnoses. All 19 US studies corresponded to prenatal control. Conclusion: These results showed that telemedicine may enhance the diagnostic services in rural communities, thus reducing the number of referrals and optimizing human and financial resources.

Introduction: Telemedicine tools offer multiple advantages to achieve an epidemiological screening of communities in rural settings countrywide. However, evidence on the cardiological pathology surveillance in these communities is limited. The feasibility of telemedicine as an electrocardiographic (EKG) mapping tool for the diagnosis and prevention of cardiological pathologies in Paraguay was investigated. Methods: A descriptive study was conducted in 60 telediagnostic centers countrywide in Paraguay to evaluate the feasibility of telemedicine as an EKG mapping tool for the diagnosis and prevention of cardiological pathologies over a period of 5 years from 2014 to 2018. The adherence rate was determined comparing yearly scheduled visits versus fulfilled visits at the telemedicine platform. Results: During the study, 246,217 remote EKG diagnoses were performed in 60 hospitals using telemedicine. The patients were 19.4% children/adolescents and 80.6% adults. The results of EKG tests in the children/adolescent group were 79.4% normal and 20.6% abnormal. The most frequent abnormal heart rhythms observed were sinusal bradicardia (10.6%), sinusal tachycardia (3.2%), and unspecified arrhythmia (2.8%). In the adult group, the results were 66.3% normal and 33.7% abnormal. The most frequent abnormal heart rhythms in this group were sinusal bradicardia (11.2%), blockade of the right branch (4.8%), and left ventricular hypertrophy (4.7%). The most frequent cardiovascular risk factors observed were the association of hypertension and obesity (40%), hypertension and diabetes (20%), and hypertension and dyslipidemia (19%). During the test period (2014-2018), the average rate of patient adherence to the prevention program was 2.26 for each 1000 diagnosis. Conclusion: These results demonstrate the feasibility of telemedicine as an EKG mapping tool for the diagnosis and prevention of cardiological pathologies in low-resource countries, thus enhancing cardiovascular disease surveillance and optimizing human and financial resources.
