Abstract Background: The implementation of Telecardiology in primary care in the city of Porto Alegre, Brazil, is a viable and promising strategy. It would decrease the distance between patient and specialized professional services by reducing unnecessary referrals and improving the quality of primary care and satisfaction of patients and health professionals. Objective: To implement a Telecardiology service and assess user satisfaction using the CARDIOSATIS scale. Methods: This was a pilot study developed by a partnership between the Institute of Cardiology and the Telehealth Center of Rio Grande do Sul. The study was carried out at Eri Flores-Vila Vargas health center in the city of Porto Alegre, from May to October 2019, and included 21 patients attending the health center. The descriptive analysis of data was performed using the SPSS program (Statistical Package for the Sciences) version 23. Data normality was checked using the Kolmogorov-Smirnov test. Statistical significance was set at 10%. Results: Mean age of participants was 43.8 ± 16.1 years. The most common risk factors in the sample were physical inactivity (81%) and smoking (43%). Most patients had normal electrocardiogram (ECG) readings. The time elapsed from the performance of the ECG test, transmission of the ECG traces to Telehealth, and return of the final ECG report to the health center was 0-7 days. The CARDIOSATIS scale revealed a high prevalence of “very satisfied” users for the general satisfaction domain, and only 14.3% of patients were dissatisfied with their health. Conclusions: Telecardiology reduced the distance between patient and the specialized professional, with a high level of patient and health professional satisfaction. Our study can serve as a basis for the implementation of a telecardiology network in the city of Porto Alegre in the future.

FUNDAMENTO: Dosagens inapropriadas e subterapêuticas anticoagulantes podem resultar em sérias complicações tromboembólicas. O uso dessa terapêutica requer especial atenção e precisa de um acompanhamento clínico e laboratorial rigoroso. OBJETIVO: Identificar fatores associados ao controle adequado dos níveis de anticoagulação oral, verificando o conhecimento e a percepção dos pacientes relacionados à terapêutica empregada. MÉTODOS: Estudo transversal que incluiu 140 pacientes acompanhados no ambulatório de anticoagulação oral, de novembro de 2005 a junho de 2006. Um questionário estruturado foi elaborado e aplicado para obtenção de características clínicas, conhecimento sobre a terapêutica, adesão ao tratamento (teste de Morisky) e percepção do paciente. RESULTADOS: As principais indicações para uso do anticoagulação oral foram fibrilação atrial (61,4%) e prótese metálica (55%). O tempo de uso variou entre 24 e 72 meses, e o femprocumona (58%) foi o mais empregado. Em relaçãoà percepção da terapêutica, 95% dos pacientes mencionaram preocupação com o uso diário dessa medicação. A realização periódica de exames de sangue (21,4%) e a tomada rigorosa de anticoagulação oral (12,8%) foram compreendidas como limitantes. Observou-se conhecimento adequado entre os pacientes com international normalized ratio (INR) fora da faixa (64%) e na aderência entre os pacientes com INR dentro da faixa terapêutica (54%), porém sem significância estatística. CONCLUSÃO: Os resultados deste estudo demonstraram uma prevalência de pacientes em uso de anticoagulação oral com o INR dentro dos valores ideais, embora tenha sido grande a porcentagem de pacientes não-aderentes à terapêutica. O conhecimento insatisfatório quanto à terapêutica empregada e ao autocuidado torna-se evidente nessa população.

BACKGROUND: Inappropriate and subtherapeutic anticoagulants dosages may result in severe thromboembolic and bleeding complications. The use of this treatment requires special attention and strict clinical and laboratory follow-up. OBJECTIVE: To identify factors associated with appropriate control of the oral anticoagulant use, assessing the patients' knowledge and perception of the treatment. METHODS: A cross-sectional study which included 140 patients followed in the oral anticoagulation outpatient clinic from November 2005 to June 2006. A structured questionnaire was drafted and applied to obtain the clinical characteristics of the patients and their knowledge about the treatment, their compliance with the treatment (Morisky´s test) and their perception of the treatment. RESULTS: The main indications for the use of oral anticoagulation therapy were atrial fibrillation (61.4%) and a prosthetic heart valve (55%). The duration of anticoagulation ranged from 24 to 72 months, and phenprocoumon (58%) was the most commonly used anticoagulant. As to the perception of the treatment, 95% of the patients mentioned concern about daily use of this medication. Periodic blood tests (21.4%) and the strict intake of oral anticoagulant (12.8%) were considered limiting factors. Adequate knowledge was outstanding in patients with an international normalized ratio (INR) outside the therapeutic range (64%), compared to patients with an INR within the therapeutic range (62%), as well as compliance with treatment in patients with an INR within the therapeutic range (54%), but with no statistical significance. CONCLUSION: The results of this study show a prevalence of patients using oral anticoagulant with an INR within optimal values, although a high percentage of patients do not comply with the treatment. In this population it is clearly seen that they do not fully understand the treatment.
