[Feasibility and efficacy of the regional cooperative ST-segment elevation myocardial infarction rescue network among the prefectural-level city hospitals].

To investigate the feasibility and efficacy of the establishment of regional cooperative acute ST-segment elevation myocardial infarction (STEMI) rescue network among the prefectural-level city hospitals in China. Based on real-time remote electrocardiogram transmission and "120" emergency systems, we established a regional collaborative STEMI treatment network with our hospital as the network unclears including 8 second-class affiliated hospitals of Jiangsu University in 2013. STEMI treatment time, therapeutic effects and economic indexes were compared before (from January 2010 to December 2012, 180 cases, pre-network) and after (From January 2013 to December 2015, 374 cases, post-network) the establishment of the regional collaborative STEMI treatment network. Post establishment of the rescue network, mean first medical contact (FMC) to balloon (FMC-to-B) time, referral time and obtaining informed consent time were all significantly decreased from (191±41), (94±18), (25±9) minutes to (93±19), (53±18), (7±5) minutes, respectively, in comparison with the pre-network era(all <0.05). There was a trend of prolonged FMC-to-B time in proportion to aging of STEMI patients(trend <0.05). Three months post discharge, LVEF was higher (55.3%±10.7% vs. 48.8%±12.1%, <0.05) and LVEDd was lower ((49.1±10.8)mm vs.(51.8±9.2)mm, <0.05) in the post-network group compared to pre-network group.In-hospital mortality was also significantly reduced post the establishment of the rescue network (2.14%(8/374) vs. 3.89%(7/180), <0.05). The results also showed that the total costs (42 017(25 069, 75 148)yuan vs.51 030(28 137, 105 861)yuan), days of hospitalization ((9.1±4.5) days vs. (15.3±4.8)days) and percentage of medicine and consumables were all significantly decreased in the post-network group compared to pre-network group(all <0.05). Establishment of the regional cooperative rescue network is feasible among the prefectural-level city hospitals in China. Establishment of such network can improve the prognosis and decrease the FMC-to-B time, the rate of in-hospital mortality and financial burden of patients with STEMI, and serves as an effective strategy to improve the rescue ability for STEMI patients.
