The Experience of a Sustainable Large Scale Brazilian Telehealth Network.

BACKGROUND In Brazil, the majority of healthcare resources are concentrated in the largest cities, whereas most communities lack proper healthcare assistance in primary care and have difficulties accessing specialists and diagnostic examinations. Considering this, the Telehealth Network of Minas Gerais (TNMG) was created. It is a public telehealth initiative that provides support to primary healthcare (PHC), performing teleconsultation and telediagnosis (electrocardiogram [ECG], Holter, ambulatory blood pressure monitoring, spirometry, and retinography analysis) mainly for small and remote cities in the state of Minas Gerais, Brazil. PURPOSE To describe the successful experience of the TNMG in 10 years of activities. METHODS The TNMG was created in 2005 and supported PHC in 82 cities as a research project and was progressively expanded. A methodology for implementation and maintenance was developed, including quality control. Nowadays it provides support to 750 cities, 88.0% of Minas Gerais state. The examinations performed by the PHC team, with additional basic clinical data, are transmitted through the Internet to the TNMG specialists for remote interpretation. The TNMG teleconsultations system has been used by the PHC team to address written clinical questions to university staff. RESULTS Until December 2015, 2,464,999 ECGs and 73,698 teleconsultations have already been performed: on average, 2,000 ECGs and 40 teleconsultations per day in 2015. More than 95% of users have declared to be satisfied or very satisfied with the service. A recent cost-benefit analysis of the project showed that for each dollar invested, 6.1 dollars are saved as a consequence of patient referral reduction. CONCLUSIONS The TNMG is a successful example of a sustainable telehealth service, integrated to primary care centers of remote and small cities. It overcomes geographical barriers to provide specialized healthcare, reducing the number of unnecessary referrals, and contributing to improve the case-resolving capacity and the quality of the PHC.
