1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

Retention in HIV care is crucial for improved health outcomes. Malawi has a high HIV prevalence and struggles with retention despite significant progress in controlling the epidemic. Mobile health (mHealth) interventions, such as two-way texting (2wT), have shown promise in improving antiretroviral therapy (ART) retention. We explore the cost-effectiveness of a 2wT intervention in Lighthouse Trust's Martin Preuss Center (MPC) in Lilongwe, Malawi, that sends automated SMS visit reminders, weekly motivational messages, and supports direct communication between clients and healthcare workers. Costs and retention (in care at 12 months) rates were compared between 468 2wT and 468 standard of care (SOC) clients. Incremental cost-effectiveness ratios were calculated. Scenario analyses were conducted to estimate costs if 2wT expanded. The 2wT group had higher retention (79%) than SOC (67%) at 12 months post-ART initiation. For 468 clients, the annual costs for 2wT were $36 670.38 compared to SOC's $33 458.72, with an ICER of $24 705 per additional percent of clients retained. With small populations, 2wT is costlier but more effective. However, expanding 2wT to all new ART clients at MPC would save $105 315 per additional percent of clients retained at 12 months. Scaling-up 2wT to four other high-burden facilities (2901 clients) could save $723 739 per additional percent of clients retained in care, suggesting significant potential cost savings. 2wT appears cost-effective to improve 12-month retention among new ART initiates in this setting. Despite potential limitations, mHealth interventions improve client outcomes and save costs, supporting their integration into HIV care programs. RESUMEN: La retención de pacientes dentro del sistema de salud es crucial en la atención del VIH para obtener mejores resultados de salud. Malaui tiene una alta tasa de prevalencia de VIH y tiene problemas con la retención, a pesar de haber progresado de manera significativa en el control de la epidemia. Intervenciones de salud móvil (mSalud), como los sistemas de mensajes de texto bidireccionales o de doble vía (2wT), han mostrado promesa en términos de aumentar retención en terapia antirretroviral (TAR). Aquí exploramos la relación costo-efectividad de una intervención 2wT en el centro médico Lighthouse Trust's Martin Preuss Center (MPC), en Lilongwe, Malaui, que manda con mensajes SMS recordatorios automatizados de visita, frases motivadoras semanales, y apoya la comunicación directa entre clientes y prestadores de salud. Se compararon los costos y las tasas de retención (aún bajo cuidado tras 12 meses) entre 468 clientes con la intervención 2wT y 468 clientes con el estándar de atención. Se calcularon las relaciones de costo-efectividad incremental (RCEI). Se condujeron análisis de escenarios para estimar el costo de expandir la intervención 2wT. El grupo con 2wT presentó mayor retención (79%) que el de atención estándar (67%), a 12 meses de haber iniciado la TAR. Los costos anuales para 468 clientes con 2wT fueron de $36 670.38, contra $33 458.72 de aquellos que recibieron el estándar, con una RCEI de $24 705 por cada percentil adicional de clientes retenidos. Con poblaciones pequeñas, 2wT es más costoso, aunque más efectivo. Sin embargo, si se expandiera el acceso a 2wT a todos los nuevos clientes de TAR en el MPC, se ahorrarían $105 315 por cada percentil adicional de clientes retenidos 12 meses. Ampliar 2wT a cubrir otros cuatro centros con carga elevada de clientes (2901 clientes) podría ahorrar $723 739 por cada percentil adicional de clientes retenidos bajo cuidado, lo cual sugiere un ahorro potencial muy significativo. en este escenario, el uso de 2wT muestra ser rentable y económicamente eficiente en el aumento de la retención por 12 meses de clientes recién iniciados a la TAR. A pesar de presentar algunas limitaciones potenciales, las intervenciones de mSalud mejoran los resultados de salud de los clientes y ahorran costos, apoyando su expedita integración a los programas de cuidado de VIH. RESUMO: A retenção nos cuidados de saúde para o VIH é crucial para melhorar os resultados em termos de saúde. O Malawi tem uma elevada prevalência de VIH e debate-se com a retenção, apesar dos progressos significativos no controlo da epidemia. As intervenções de saúde móvel (mHealth), como as mensagens de texto bidireccionais (2wT), mostraram-se promissoras na melhoria da retenção da terapia antirretroviral (ART). Exploramos a relação custo-eficácia de uma intervenção 2wT no Centro Martin Preuss (MPC) da Lighthouse Trust em Lilongwe, Malawi, que envia lembretes automáticos de visitas por SMS, mensagens motivacionais semanais, e apoia a comunicação direta entre clientes e profissionais de saúde. Os custos e as taxas de retenção (nos cuidados de saúde aos 12 meses) foram comparados entre 468 clientes de 2wT e 468 clientes de cuidados padrão (SOC). Foram calculados os rácios de custo-eficácia incrementais (ICER). Foram efetuadas análises de cenários para estimar os custos em caso de expansão do 2wT. O grupo 2wT registou uma maior retenção (79%) do que o grupo SOC (67%) aos 12 meses após o início da TAR. Para 468 clientes, os custos anuais do 2wT foram de 36.670,38 dólares em comparação com os 33.458,72 dólares do SOC, com um ICER de 24.705 dólares por percentagem adicional de clientes retidos. Com populações pequenas, o 2wT é mais caro, mas mais eficaz. No entanto, a expansão do 2wT a todos os novos utentes do TARV no MPC pouparia 105.315 dólares por cada percentagem adicional de utentes retidos aos 12 meses. A expansão do 2wT para quatro outras instalações de alta carga (2.901 clientes) poderia economizar US$ 723.739 por percentagem adicional de clientes retidos nos cuidados, sugerindo um potencial significativo de economia de custos. O 2wT parece ser eficaz em termos de custos para melhorar a retenção de 12 meses entre os novos iniciados no TARV neste contexto. Apesar das potenciais limitações, as intervenções de saúde móvel melhoram os resultados dos clientes e poupam custos, apoiando a sua integração nos programas de cuidados do VIH. RÉSUMÉ: La rétention dans les soins du VIH est cruciale pour améliorer les résultats en matière de santé. Le Malawi a une prévalence élevée du VIH et a des difficultés pour la rétention malgré des progrès significatifs dans le contrôle de l'épidémie. Les interventions de santé mobile (mHealth), telles que les SMS bidirectionnels (2wT), se sont révélées prometteuses pour améliorer la rétention du traitement antirétroviral (ART). Nous explorons le coût-efficacité d'une intervention 2wT au Martin Preuss Center (MPC) du Lighthouse Trust à Lilongwe, Malawi, qui envoie des rappels de visite par SMS automatisés, des messages de motivation hebdomadaires et assiste la communication directe entre les clients et les agents de santé. Les coûts et les taux de rétention (en soins à 12 mois) ont été comparés entre 468 clients 2wT et 468 clients en soins standards (SS). Des rapports coût-efficacité différentiels (RCED) ont été calculés. Des analyses de scénarios ont été menées pour estimer les coûts si l'intervention 2wT s'étendait. Le groupe 2wT présentait une rétention plus élevée (79%) que le groupe SS (67%) 12 mois après le début de l'ART. Pour 468 clients, les coûts annuels du 2wT étaient de 36 670,38 $, contre 33 458,72 $ pour SS, avec un RCED de 24 705 $ par pourcentage supplémentaire de clients retenus. Avec de petites populations, le 2wT est plus coûteux mais plus efficace. Cependant, l'extension du 2wT à tous les nouveaux clients ART du MPC permettrait d'économiser 105 315 $ par pourcentage supplémentaire de clients retenus à 12 mois. L'extension du 2wT à quatre autres établissements à forte charge de travail (2901 clients) pourrait permettre d'économiser 723 739 $ par pourcentage supplémentaire de clients retenus dans les soins, ce qui suggère des économies potentielles importantes. Le 2wT semble rentable pour améliorer la rétention à 12 mois parmi les nouveaux initiés à l'ART dans ce contexte. Malgré leurs limites potentielles, les interventions mHealth améliorent les résultats pour les clients et permettent de réduire les coûts, favorisant ainsi leur intégration dans les programmes de soins du VIH.
