Results and evaluation of the expansion of a model of comprehensive care for Chagas disease within the National Health System: The Bolivian Chagas network

Background: Most people with chronic Chagas disease do not receive specific care and therefore are undiagnosed and do not receive accurate treatment. This manuscript discusses and evaluates a collaborative strategy to improve access to healthcare for patients with Chagas in Bolivia, a country with the highest prevalence of Chagas in the world. Methods: With the aim of reinforcing the Chagas National Programme, the Bolivian Chagas Platform was born in 2009. The first stage of the project was to implement a vertical pilot program in order to introduce and consolidate a consensual protocol-based healthcare, working in seven centers (Chagas Platform Centers). From 2015 on the model was extended to 52 primary healthcare centers, through decentralized, horizontal scaling-up. To evaluate the strategy, we have used the WHO ExpandNet program. Results: The strategy has significantly increased the number of patients cared for, with 181,397 people at risk of having T. cruzi infection tested and 57,871 (31·9%) new diagnostics performed. In those with treatment criteria, 79·2% completed the treatment. The program has also trained a significant number of health personnel through the specific Chagas guidelines (67% of healthcare workers in the intervention area). Conclusions: After being recognized by the Chagas National Programme as a healthcare model aligned with national laws and priorities, the Bolivian platform of Chagas as an innovation, includes attributes that they have made it possible to expand the strategy at the national level and could also be adapted in other countries

Implementación de un modelo de comunicación en Chagas basado en la estrategia de educación por pares

Objectives:  this study aims to identify changes in the perspectives, knowledges, attitudes and practices of the relatives of a group of patients treated in the Platform of integral care of Chagas, and trained as peer educators, and if that changes led to an increase of the Chagas demand in the health services of Valle Alto, in Cochabamba department. Methods:  we compared the results of the survey conducted on 32 relatives of 8 patients trained in 2018 (group A) with a similar survey conducted on 64 family members of 16 patients treated in 2017 (group B) who were not specifically trained, but received the counseling routinely provided by the health staff. Results:  the results show that relatives of peer educators have modified their knowledge, attitudes, practices and perceptions about Chagas disease and this change has influenced the demand for diagnosis of this disease. Conclusions:  the strategy of peer education has proven to be effective, easy to apply by a nursing staff in the 1ª and 2ª levels of care, and allows reaching affected families at an affordable cost.Objetivos: el presente estudio evalúa el cambio en las perspectivas, conocimientos, actitudes y prácticas de los familiares de un grupo de pacientes capacitados con la estrategia de educación por pares que fueron tratados en la Plataforma de atención integral de Chagas, y si ese cambio se traduce en un aumento de la demanda de atención integral de Chagas en los servicios de salud del Valle Alto de Cochabamba. Métodos:  se comparó los resultados de la encuesta realizada en 32 familiares de 8 pacientes capacitados en 2018 (grupo A) con una encuesta similar realizada en 64 familiares de 16 pacientes tratados en 2017 (grupo B) que no fueron capacitados, pero en cambio recibieron la consejería que provee el personal de salud de forma rutinaria. Resultados: los resultados obtenidos muestran que los familiares de pacientes educadores pares han modificado sus conocimientos, actitudes, prácticas y percepciones sobre la enfermedad de Chagas y este cambio ha influido positivamente la demanda de atención de servicios integrales para dicha enfermedad.
