Objectives: The Quebec Emergency Department Management Guide (QEDMG) is a unique document with 78 recommendations designed to improve the organization of emergency departments (EDs) in the province of Quebec. However, no study has examined how this guide is perceived or used by rural health care management., Methods: We invited all directors of professional services (DPS), directors of nursing services (DNS), head nurses (HN), and emergency department directors (EDD) working in Quebec's rural hospitals to complete an online survey (144 questions). Simple frequency analyses (percentage [%] and 95% confidence interval) were conducted to establish general familiarity and use of the QEDMG, as well as perceived usefulness and implementation of its recommendations., Results: Seventy-three percent (19/26) of Quebec's rural EDs participated in the study. A total of 82% (62/76) of the targeted stakeholders participated. Sixty-one percent of respondents reported being "moderately or a lot" familiar with the QEDMG, whereas 77% reported "almost never or sometimes" refer to this guide. Physician management (DPS, EDD) were more likely than nursing management (DNS and especially HN) to report "not at all" or "little" familiarity on use of the guide. Finally, 98% of the QEDMG recommendations were considered useful., Conclusions: Although the QEDMG is considered a useful guide for rural EDs, it is not optimally known or used in rural EDs, especially by physician management. Stakeholders should consider these findings before implementing the revised versions of the QEDMG.

Objectives: It remains unclear whether ST-elevation myocardial infarction (STEMI) patients transported by ambulance over long distances are at risk for clinical adverse events. We sought to determine the frequency of clinical adverse events in a rural population of STEMI patients and to evaluate the impact of transport time on the occurrence of these events in the presence of basic life support paramedics., Methods: We performed a health records review of 880 consecutive STEMI patients transported to a percutaneous coronary intervention centre. Patients had continuous electrocardiogram and vital sign monitoring during transport. A classification of clinically important and minor adverse events was established based on a literature search and expert consensus. A multivariate ordinal logistic regression model was used to study the association between transport time (0-14, 15-29, ≥30 minutes) and the occurrence of overall clinical adverse events., Results: Clinically important and minor events were experienced by 18.5% and 12.2% of STEMI patients, respectively. The most frequent clinically important events observed were severe hypotension (6.1%) and ventricular tachycardia/ventricular fibrillation (5.1%). Transport time was not associated with a higher risk of experiencing clinical adverse events (p=0.19), but advanced age was associated with adverse events (p=0.03). No deaths were recorded during prehospital transport., Conclusions: In our study of rural STEMI patients, clinical adverse events were common (30.7%). However, transport time was not associated with the occurrence of adverse clinical events in these patients.

Objective: Repeated or serial 12-lead electrocardiograms (ECGs) in the prehospital setting may improve management of patients with subtle ST-segment elevation (STE) or with a ST-segment elevation myocardial infarction (STEMI) that evolves over time. However, there is a minimal amount of scientific evidence available to support the clinical utility of this method. Our objective was to evaluate the use of serial 12-lead ECGs to detect STEMI in patients during transport in a Canadian emergency medical services (EMS) jurisdiction., Methods: We performed a retrospective study of suspected STEMI patients transported by EMS in the Chaudière-Appalaches region (Québec, Canada) between August 2006 and December 2013. Patients were monitored by a serial 12-lead ECG system where an averaged ECG was transmitted every 2 minutes. Following review by an emergency physician, ECGs were grouped as having either a persistent STE or a dynamic STE that evolved over time., Results: A total of 754 suspected STEMI patients were transported by EMS during the study period. Of these, 728 patients met eligibility criteria and were included in the analysis. A persistent STE was observed in 84.3% (614/728) of patients, while the remaining 15.7% (114/728) had a dynamic STE. Among those with dynamic STE, 11.1% (81/728) had 1 ST-segment change (41 no-STEMI to STEMI; 40 STEMI to no-STEMI) and 4.5% (33/728) had ≥ 2 ST-segment changes (17 no-STEMI to STEMI; 16 STEMI to no-STEMI). Overall, in 8.0% (58/728) of the cohort, STEMI was identified on a subsequent ECG following an initial no-STEMI ECG., Conclusions: Through recognition of transient ST-segment changes during transport via the prehospital serial 12-lead ECG system, STEMI was identified in 8% of suspected STEMI patients who had an initial no-STEMI ECG. Key words: electrocardiography; emergency medical services; ST-elevation myocardial infarction; prehospital dynamic ECG.

Background: As per American Heart Association/American College of Cardiology guidelines, the delay between first medical contact and balloon inflation should not exceed 90 min for primary percutaneous coronary intervention (PCI). In North America, few prehospital systems have been developed to grant rural populations timely access to PCI., Objectives: The objective of the present study was to evaluate the ability of an ST-segment elevation myocardial infarction (STEMI) system serving suburban and rural populations to achieve the recommended 90-min interval benchmark for PCI., Methods: A prehospital telemedicine program was implemented in a rural and suburban region of the Quebec province. Three patient groups with STEMI were created according to trajectory: 1) patients already en route to a PCI center, 2) patients initially directed to the nearest hospital who were subsequently diverted to a PCI center during transport, and 3) patients directed to the nearest hospital without transfer for PCI. Time intervals were compared across groups., Results: Of the 208 patients diagnosed with STEMI, 14.9% were already on their way to a hospital with PCI capabilities, 75.0% were rerouted to a PCI center, and 10.1% were directed to the nearest local hospital. All patients but one arrived at the PCI center within the 60-min prehospital care interval, considering an additional 30 min for balloon inflation at the PCI center., Conclusion: This study demonstrated that a regionalized prehospital system for STEMI patients could achieve the recommended 90-min interval benchmark for PCI, while giving timely access to PCI to rural populations that would not otherwise have access to this treatment., (Copyright © 2015 The Authors.
