Dataset Information

Few with ST-segment elevation myocardial infarction are diagnosed within 10 minutes from first medical contact, and women have longer delay times than men.

ABSTRACT: Background:Previous reports have questioned the feasibility and gender equality of obtaining a prehospital ECG within 10 minutes of ambulance arrival for patients with ST-segment elevation myocardial infarction (STEMI). The main objective of this study was to investigate the proportion of STEMI patients with a prehospital ECG within 10 minutes of ambulance arrival. The secondary objective was to study the gender differences in delay times in prehospital STEMI care. Methods:This study was a retrospective study based on 539 patients with STEMI at the investigating hospital. Ambulance and medical charts, as well as the national quality registry "SWEDEHEART", were reviewed for each patient for demographics and time information. Results:A prehospital ECG was obtained within 10 minutes of ambulance arrival for 99 (29%) of the men and 19 (14%) of the women, p = 0.001. Women had a 2 minutes longer delay between ambulance arrival and prehospital ECG (95% CI 0-4 min, p = 0.018) than men. Women also had a significantly longer patient delay. None of the other time intervals differed among men and women. Conclusions:Only for a minority of patients is a prehospital ECG taken within the recommended ten minutes from ambulance arrival. Women have longer patient delay times, as well as delay times to the acquisition of a prehospital ECG than men. Improvements of prehospital ECG acquisition and adjustments of the guidelines are warranted.

Project description:The Mission: Lifeline STEMI Systems Accelerator program, implemented in 16 US metropolitan regions, resulted in more patients receiving timely reperfusion. We assessed whether implementing key care processes was associated with system performance improvement. Hospitals (n=167 with 23 498 ST-segment-elevation myocardial infarction patients) were surveyed before (March 2012) and after (July 2014) program intervention. Data were merged with patient-level clinical data over the same period. For reperfusion, hospitals were grouped by whether a specific process of care was implemented, preexisting, or never implemented. Uptake of 4 key care processes increased after intervention: prehospital catheterization laboratory activation (62%-91%; P<0.001), single call transfer protocol from an outside facility (45%-70%; P<0.001), and emergency department bypass for emergency medical services direct presenters (48%-59%; P=0.002) and transfers (56%-79%; P=0.001). There were significant differences in median first medical contact-to-device times among groups implementing prehospital activation (88 minutes implementers versus 89 minutes preexisting versus 98 minutes nonimplementers; P<0.001 for comparisons). Similarly, patients treated at hospitals implementing single call transfer protocols had shorter median first medical contact-to-device times (112 versus 128 versus 152 minutes; P<0.001). Emergency department bypass was also associated with shorter median first medical contact-to-device times for emergency medical services direct presenters (84 versus 88 versus 94 minutes; P<0.001) and transfers (123 versus 127 versus 167 minutes; P<0.001). The Accelerator program increased uptake of key care processes, which were associated with improved system performance. These findings support efforts to implement regional ST-segment-elevation myocardial infarction networks focused on prehospital catheterization laboratory activation, single call transfer protocols, and emergency department bypass.
