Multifaceted Strategy Based on Automated Text Messaging After a Recent Heart Failure Admission: The MESSAGE-HF Randomized Clinical Trial.

Importance: Readmissions after an index heart failure (HF) hospitalization are a major contemporary health care problem. Objective: To evaluate the feasibility and efficacy of an intensive telemonitoring strategy in the vulnerable period after an HF hospitalization. Design, Setting, and Participants: This randomized clinical trial was conducted in 30 HF clinics in Brazil. Patients with left ventricular ejection fraction less than 40% and access to mobile phones were enrolled up to 30 days after an HF admission. Data were collected from July 2019 to July 2022. Intervention: Participants were randomly assigned to a telemonitoring strategy or standard care. The telemonitoring group received 4 daily short message service text messages to optimize self-care, active engagement, and early intervention. Red flags based on feedback messages triggered automatic diuretic adjustment and/or a telephone call from the health care team. Main Outcomes and Measures: The primary end point was change in N-terminal pro-brain natriuretic peptide (NT-proBNP) from baseline to 180 days. A hierarchical win-ratio analysis incorporating blindly adjudicated clinical events (cardiovascular deaths and HF hospitalization) and variation in NT-proBNP was also performed. Results: Of 699 included patients, 460 (65.8%) were male, and the mean (SD) age was 61.2 (14.5) years. A total of 352 patients were randomly assigned to the telemonitoring strategy and 347 to standard care. Satisfaction with the telemonitoring strategy was excellent (net promoting score at 180 days, 78.5). HF self-care increased significantly in the telemonitoring group compared with the standard care group (score difference at 30 days, -2.21; 95% CI, -3.67 to -0.74; P = .001; score difference at 180 days, -2.08; 95% CI, -3.59 to -0.57; P = .004). Variation of NT-proBNP was similar in the telemonitoring group compared with the standard care group (telemonitoring: baseline, 2593 pg/mL; 95% CI, 2314-2923; 180 days, 1313 pg/mL; 95% CI, 1117-1543; standard care: baseline, 2396 pg/mL; 95% CI, 2122-2721; 180 days, 1319 pg/mL; 95% CI, 1114-1564; ratio of change, 0.92; 95% CI, 0.77-1.11; P = .39). Hierarchical analysis of the composite outcome demonstrated a similar number of wins in both groups (telemonitoring, 49 883 of 122 144 comparisons [40.8%]; standard care, 48 034 of 122 144 comparisons [39.3%]; win ratio, 1.04; 95% CI, 0.86-1.26). Conclusions and Relevance: An intensive telemonitoring strategy applied in the vulnerable period after an HF admission was feasible, well-accepted, and increased scores of HF self-care but did not translate to reductions in NT-proBNP levels nor improvement in a composite hierarchical clinical outcome.

Emergency medical coordination using a web platform: a pilot study.

OBJECTIVE: To describe a management system for emergency medical coordination based on the worldwide web of computers. METHODS: The emergency coordination system was developed according to an evolving software model for prototype development. Communication between users and the system was implemented by means of web technologies. The system was developed on a personal homepage and the database was developed using MySQL. The prototype was based on the medical coordination process of the Thirteenth Regional Healthcare Division of the State of São Paulo (Southeastern Brazil) and was applied to 26 municipalities within this regional division, for four consecutive weeks in September 2009. The system made it possible to document requests in chronological order, without allowing editing of data already entered, and ensured hierarchical confidential access to the information for each participant in the system. RESULTS: The system presented 100% availability, reliability and integrity of information. A total of 1,046 requests were made to the system, of which 703 (68%) were completed. The solicitants already presented 98% adherence to the system in the first week of application, while adherence among service providers gradually increased (37% in the fourth week). The municipalities closest to Ribeirão Preto that did not have high-complexity providers were the ones that most used the system. CONCLUSIONS: Medical coordination of emergency requests through the worldwide web of computers was shown to be feasible and reliable, and it enabled transparency within the process and direct access to information for managers. It allowed indicators to be constructed in order to monitor and improve the process, from the perspective of creating semi-automated coordination and advances in system organization.

Regulação médica em emergência pela plataforma web: um estudo piloto / Regulación médica en emergencia por la plataforma web: un estudio piloto / Emergency medical coordination using a web platform: a pilot study

OBJETIVO: Descrever um sistema gestor de regulação médica em emergência baseado na rede mundial de computadores. MÉTODOS: O Sistema de Regulação de Urgências e Emergências foi desenvolvido segundo modelo evolutivo de software de prototipação. A comunicação entre os usuários e o sistema foi implementada utilizando tecnologias web; o sistema foi desenvolvido em personal home page (PHP) e o banco de dados, em MySQL. O protótipo foi baseado no processo de regulação médica da Divisão Regional de Saúde XIII do Estado de São Paulo e aplicado a 26 municípios dessa regional durante quatro semanas consecutivas em setembro de 2009. O sistema possibilitou a documentação das solicitações em ordem cronológica, sem permitir edição de dados já inseridos e garantindo o acesso hierarquizado e sigiloso às informações para cada participante do sistema. RESULTADOS: O sistema apresentou 100 por cento de disponibilidade, confiabilidade e integridade da informação. Foram realizadas 1.046 solicitações ao sistema, das quais 703 (68 por cento) foram completadas. Os solicitantes apresentaram 98 por cento de adesão ao sistema na primeira semana de aplicação, e a adesão dos prestadores de serviço foi gradativa (37 por cento na quarta semana). Os municípios mais próximos de Ribeirão Preto que não possuem prestadores de alta complexidade foram os que mais utilizaram o sistema. CONCLUSÕES: A regulação médica de solicitações de emergência pela rede mundial de computadores mostrou-se exeqüível e confiável, possibilitando a transparência do processo e acesso direto às informações por parte dos gestores. Possibilitou a construção de indicadores para monitorizar e aprimorar o processo, na perspectiva da criação de uma regulação semi-automatizada e de avanços na organização do sistema.
