Abstract Background Timely management of Acute Coronary Syndrome (ACS) is essential to improving patient outcomes. In Brazil's Unified Health System, variability in adherence to evidence-based protocols in prehospital emergency care represents a significant barrier to effective ST-elevation myocardial infarction (STEMI) care. Purpose To determine the effectiveness of structured continuous improvement programs integrating Lean Healthcare principles, Improvement Science methodologies and while integrating telehealth strategies to enhance ACS care processes and patient outcomes within Brazil's fixed prehospital units. Results Preliminary findings indicate progressive improvement in ACS care process indicators among participating units. Adherence to thrombolytic therapy increased from 52% at baseline to 60% (p0.01), representing a 15.4% relative improvement. This was accompanied by a significant reduction in critical time metrics: median door-to-needle time decreased from 58 to 42 minutes (28% reduction), while door-to-ECG (Figure 1) time improved from 24 to 14 minutes (42% reduction, p0.001). The intervention also optimized overall system efficiency: total prehospital length of stay decreased from 797 to 534 minutes (33% reduction), and interfacility transfer time was reduced from 621 to 476 minutes (23% improvement), demonstrating enhanced patient flow coordination (Figure 2). Clinical outcomes remained stable despite increased patient volume: the mortality rate maintained at 2% (vs 2% baseline) while the elopement rate decreased from 4.1% to 3.0%, and 72% of teleconsultation cases received specialist feedback within target timeframe. Conclusion(s) The integration of telediagnosis and cardiology teleconsultation with Lean and Improvement Science methods proved feasible and improved ACS care processes in Brazil’s pre-hospital emergency network. This initiative underscores the value of structured quality improvement strategies for sustainable, evidence-based enhancement of acute cardiovascular care.
Toth et al. (Fri,) conducted a observational in Acute Coronary Syndrome (ACS). Structured continuous improvement program integrating Lean principles and telehealth vs. Baseline (pre-intervention) was evaluated on Adherence to thrombolytic therapy (p=<0.01). A structured continuous improvement program integrating Lean principles and telehealth increased adherence to thrombolytic therapy from 52% to 60% (p<0.01) in prehospital ACS care.
