ABSTRACT
BACKGROUND: We report the preliminary data from a regional registry on ST-elevation myocardial infarction (STEMI) patients treated with primary angioplasty in Apulia, Italy; the region is covered by a single public health-care service, a single public emergency medical service (EMS), and a single tele-medicine service provider. METHODS: Two hundred and ninety-seven consecutive patients with STEMI transferred by regional free public EMS 1-1-8 for primary-PCI were enrolled in the study; 123 underwent pre-hospital electrocardiograms (ECGs) triage by tele-cardiology support and directly referred for primary-PCI, those remaining were just transferred by 1-1-8 ambulances for primary percutaneous coronary intervention (PCI) (diagnosis not based on tele-medicine ECG; already hospitalised patients, emergency-room without tele-medicine support). Time from first ECG diagnostic for STEMI to balloon was recorded; a time-to-balloon <1 h was considered as optimal and patients as timely treated. RESULTS: Mean time-to-balloon with pre-hospital triage and tele-cardiology ECG was significantly shorter (0:41 ± 0:17 vs 1:34 ± 1:11 h, p<0.001, -0:53 h, -56%) and rates of patients timely treated higher (85% vs 35%, p<0.001, +141%), both in patients from the 'inner' zone closer to PCI catheterisation laboratories (0:34 ± 0:13 vs 0:54 ± 0:30 h, p<0.001; 96% vs 77%, p<0.01, +30%) and in the 'outer' zone (0:52 ± 0:17 vs 1:41 ± 1:14 h, p<0.001; 69% vs 29%, p<0.001, +138%). Results remained significant even after multivariable analysis (odds ratio for time-to-balloon 0.71, 95% confidence interval (CI) 0.63-0.80, p<0.001; 1.39, 95% CI 1.25-1.55, p<0.001, for timely primary-PCI). CONCLUSIONS: Pre-hospital triage with tele-cardiology ECG in an EMS registry from an area with more than one and a half million inhabitants was associated with shorter time-to-balloon and higher rates of timely treated patients, even in 'rural' areas.

BACKGROUND: Telemedicine has been shown to improve quality of health-care delivery in several fields of medicine; its cost-effectiveness, however, is still a matter of debate. HYPOTHESIS: Pre-hospital telemedicine electrocardiogram triage for regional public emergency medical service may reduce costs. METHODS: An economic evaluation (cost analysis) was performed from the perspective of regional health-care system. Patients enrolled in the study and considered for cost analysis were those who called the local emergency medical service (EMS; dialing 1-1-8) during 2012 and underwent prehospital field triage with a telemedicine electrocardiogram (ECG) in the case of suspected acute cardiac disease (acute coronary syndrome, arrhythmia). The prehospital ECGs were read by a remote cardiologist, available 24/7. Cost savings associated with this method were calculated by subtracting the cost of prehospital triage with telemedicine support from the cost of conventional emergency department triage (ECG and consultation by a cardiologist). RESULTS: During 2012, the regional EMS performed 109 750 ECGs by telemedicine support. The associated total cost for the regional health-care system was 1 833 333, with a 16.70 cost per single ECG/consultation. Given the cost of similar conventional emergency department treatment from a regional rate list of 24.80 to 55.20, the savings was 8.10 to 38.40 per ECG/consultation (total savings, 891 759.50 to 4 219 379.50). The cost for ruling out an acute cardiac disease was 25.30; for a prehospital diagnosis of cardiovascular disease, 49.20. With 629 prehospital diagnoses of ST-elevation myocardial infarction and reported reductions in mortality thanks to prehospital diagnosis deduced from prior studies, 69 lives per year presumably could be saved, with a cost per quality-adjusted life year gained of 1927, 990/ - 2508 after correction for potential savings. CONCLUSIONS: Prehospital EMS triage with telemedicine ECG in patients with suspected acute cardiac disease may reduce health-care costs.
