SUMMARY OBJECTIVE: This study aimed to characterize teleconsultations in neurology executed by Regula+Brasil project in Recife, a capital city in northeastern Brazil. METHODS: A descriptive study carried out by four private hospitals, in a partnership with the Ministry of Health in Brazil. Teleconsultation was performed preferably in the video modality. Conditions eligible for teleconsultation were headache, epilepsy, and cerebrovascular disorders. Period of analysis was May to September 2020. RESULTS: A total of 243 teleconsultations were analyzed, of which 76.95% was a first appointment. In 48.97% of cases, the teleconsultation represented the first opportunity for the patient to be consulted with the specialist. Among cases of first appointment, 20.16% were further referred to a face-to-face consultation and 21.81% could be redirected to primary health care. Headache disorders were the most predominant clinical conditions. CONCLUSIONS: The implementation and development of telemedicine by Regula+Brasil during the COVID-19 pandemic represented an opportunity to assess the value of having teleconsultations added along the line of care from primary care to a medical specialty, promoting the coordination of care across different levels of complexity of care in the health system and improving access to specialized care.

RESUMO Doppler transcraniano (DTC) é um componente estratégico da prevenção primária do acidente vascular cerebral (AVC) em crianças com doença falciforme (DF). Este estudo foi realizado para examinar as características do DTC de crianças com DF em nove centros médicos diferentes no Brasil. Métodos: DTC foi realizado de acordo com o protocolo de Stroke Prevention Trial in Sickle Cell Anemia Protocol (STOP). Resultados: Dos 396 pacientes avaliados, 69,5% eram homozigotos para hemoglobina SS. DTC foi anormal em 4,8%, condicional em 12,6%, inadequado em 5,3% e anormalmente baixo em 1%. As máximas velocidades de fluxo médio foram 121 ± 23,83cm/s e 124 ± 27,21 cm/s nas artérias cerebrais media esquerda e direita, respectivamente. Um total de 28,8% dos pacientes (média de 9,19 ± 5,92 anos) foram avaliados com o DTC pela primeira vez. Conclusões: Pacientes com DF foram avaliados com DTC numa idade considerada avançada, o que representa uma importante oportunidade perdida para a prevenção de AVC nessa população. Uma vez que a triagem com DTC em pacientes com DF é essencial para detectar aqueles com alto risco de AVC, recomenda-se que essa triagem seja amplamente disponível no país.

ABSTRACT Transcranial doppler (TCD) is a strategic component of primary stroke prevention in children with sickle cell disease (SCD). This study was conducted to examine the TCD characteristics of children with SCD in nine different medical centers in Brazil. Methods: Transcranial doppler was performed in accordance with the Stroke Prevention Trial in Sickle Cell Anemia Protocol. Results: Of the 396 patients, 69.5% had homozygous SS hemoglobin. The TCD result was abnormal in 4.8%, conditional in 12.6%, inadequate in 4.3% and abnormally low in 1% of patients. The highest mean flow velocities were 121±23.83cm/s and 124±27.21cm/s in the left and right middle cerebral artery respectively. A total of 28.8% patients (mean age 9.19±5.92 years) were evaluated with TCD for the first time. Conclusions: The SCD patients were evaluated with TCD at an older age, representing an important missed opportunity for stroke prevention. Since TCD screening in patients with SCD is important to detect those at high risk for stroke, it is recommended that this screening should be made more readily available.
