Impact of a telemedicine-guided, population-based, STEMI network on reperfusion strategy, efficiency, and outcomes: Impact of telemedicine on STEMI management.

aimsA telemedicine-guided strategy increases the access to and efficiency of ST-elevation myocardial infarction (STEMI) networks resulting in increased access to, and reduced disparities in, acute myocardial infarction (AMI) care between rural and urban areas. METHODS AND

resultsThe Latin America Telemedicine Infarct Network (LATIN) was developed for poor and remote regions in Brazil and Colombia that lacked coordinated AMI systems of care. It strategically connects small clinics and primary care health centres (spokes) to hubs with 24/7 percutaneous coronary intervention (PCI) capability. Experts at three remote sites provide urgent electrocardiogram (ECG) diagnosis and tele-consultation for the entire network. Data from the busiest LATIN site, the Santa Marcelina Hospital in Sao Paolo, Brazil, were compared with health statistics from Sistema Unico de Saude (Brazilian Public Health System - SUS). A total of 192 centres were networked using standardised and guideline-based protocols for AMI care. Overall, 313,897 patients were remotely screened, 3,572 AMI diagnosed (1.1%), and 1,636 AMI urgently reperfused (45.8%), mainly by primary PCI (n=1,351; 83%).

conclusionsIn conclusion, a comparison between a pre-LATIN cohort from SUS (1,015) and a LATIN cohort from Santa Marcelina Hospital (1,247) revealed increased reperfusion with PCI (65.52% vs 75.2%), increased cost ($2,037.12 vs $2,246.40, p<0.005), a statistically significant reduction in PCI mortality (8.5% vs 4.3% p<0.01) and a non-significant reduction in mortality overall amongst all treatment pathways (9.69% vs 9.43%, p=0.931).
