Factors for delays in door-to-balloon time ≤ 90 min in an electrocardiogram triage system among patients with ST-segment elevation myocardial infarction: a retrospective study. Int J Emerg Med 2023; 16:77. [PMID: 37919686 PMCID: PMC10621087 DOI: 10.1186/s12245-023-00562-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 10/26/2023] [Indexed: 11/04/2023] Open
Abstract
BACKGROUND Door to balloon time is a crucial factor of mortality in patients with ST-segment elevation myocardial infarction. However, the factors that contribute to failure of achieving door to balloon time ≤ 90 min in an electrocardiogram triage system remain unknown. METHODS This single-center retrospective observational study collected data from consecutive patients with ST-segment elevation myocardial infarction from April 2016 to March 2021. The primary outcome was the failure to achieve door to balloon time ≤ 90 min. A multivariate logistic regression model was performed to predict factors associated with failure to achieve door to balloon time ≤ 90 min. RESULTS In total, 190 eligible patients were included. Of these, the 139 (73.2%) patients with door to balloon time ≤ 90 min were significantly younger compared to those with door to balloon time > 90 min (p = 0.02). However, there was no significant difference in sex and timing of hospital arrival between the door to balloon time ≤ 90 and > 90 min groups. Presence of chest pain and ambulance usage were significantly more frequent in patients with door to balloon time ≤ 90 min (p ≤ 0.01, p = 0.02, respectively). Multivariate analysis showed that absence of chest pain (adjusted odds ratio 4.76; 95% confidence interval, 2.04-11.1; p < 0.01) and non-ambulance usage (adjusted odds ratio 3.53; 95% confidence interval, 1.57-7.94; p < 0.01) are predictive factors of failure to achieve door to balloon time ≤ 90 min. CONCLUSION Patients without chest pain as the chief complaint or non-ambulance usage were significantly associated with the failure to achieve door to balloon time ≤ 90 min.

Disparities in Emergency Medical Services Care Delivery in the United States: A Scoping Review. PREHOSP EMERG CARE 2022; 27:1058-1071. [PMID: 36369725 DOI: 10.1080/10903127.2022.2142344] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Accepted: 10/25/2022] [Indexed: 11/14/2022]
Abstract
BACKGROUND Emergency medical services (EMS) often serve as the first medical contact for ill or injured patients, representing a critical access point to the health care delivery continuum. While a growing body of literature suggests inequities in care within hospitals and emergency departments, limited research has comprehensively explored disparities related to patient demographic characteristics in prehospital care. OBJECTIVE We aimed to summarize the existing literature on disparities in prehospital care delivery for patients identifying as members of an underrepresented race, ethnicity, sex, gender, or sexual orientation group. METHODS We conducted a scoping review of peer-reviewed and non-peer-reviewed (gray) literature. We searched PubMed, CINAHL, Web of Science, Proquest Dissertations, Scopus, Google, and professional websites for studies set in the U.S. between 1960 and 2021. Each abstract and full-text article was screened by two reviewers. Studies written in English that addressed the underrepresented groups of interest and investigated EMS-related encounters were included. Studies were excluded if a disparity was noted incidentally but was not a stated objective or discussed. Data extraction was conducted using a standardized electronic form. Results were summarized qualitatively using an inductive approach. RESULTS One hundred forty-five full-text articles from the peer-reviewed literature and two articles from the gray literature met inclusion criteria: 25 studies investigated sex/gender, 61 studies investigated race/ethnicity, and 58 studies investigated both. One study investigated sexual orientation. The most common health conditions evaluated were out-of-hospital cardiac arrest (n = 50), acute coronary syndrome (n = 36), and stroke (n = 31). The phases of EMS care investigated included access (n = 55), pre-arrival care (n = 46), diagnosis/treatment (n = 42), and response/transport (n = 40), with several studies covering multiple phases. Disparities were identified related to all phases of EMS care for underrepresented groups, including symptom recognition, pain management, and stroke identification. The gray literature identified public perceptions of EMS clinicians' cultural competency and the ability to appropriately care for transgender patients in the prehospital setting. CONCLUSIONS Existing research highlights health disparities in EMS care delivery throughout multiple health outcomes and phases of EMS care. Future research is needed to identify structured mechanisms to eliminate disparities, address clinician bias, and provide high-quality equitable care for all patient populations.

Can a Healthcare Quality Improvement Initiative Reduce Disparity in the Treatment Delay among ST-Segment Elevation Myocardial Infarction Patients with Different Arrival Modes? Evidence from 33 General Hospitals and Their Anticipated Impact on Healthcare during Disasters and Public Health Emergencies. Healthcare (Basel) 2021; 9:1462. [PMID: 34828508 PMCID: PMC8621169 DOI: 10.3390/healthcare9111462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 10/25/2021] [Accepted: 10/26/2021] [Indexed: 11/18/2022] Open
Abstract
(1) Background: Chest pain center accreditation has been associated with improved timelines of primary percutaneous coronary intervention (PCI) for ST-segment elevated myocardial infarction (STEMI). However, evidence from low- and middle-income regions was insufficient, and whether the sensitivity to improvements differs between walk-in and emergency medical service (EMS)-transported patients remained unclear. In this study, we aimed to examine the association of chest pain center accreditation status with door-to-balloon (D2B) time and the potential modification effect of arrival mode. (2) Methods: The associations were examined using generalized linear mixed models, and the effect modification of arrival mode was examined by incorporating an interaction term in the models. (3) Results: In 4186 STEMI patients, during and after accreditation were respectively associated with 65% (95% CI: 54%, 73%) and 71% (95% CI: 61%, 79%) reduced risk of D2B time being more than 90 min (using before accreditation as the reference). Decreases of 27.88 (95% CI: 19.57, 36.22) minutes and 26.55 (95% CI: 17.45, 35.70) minutes in D2B were also observed for the during and after accreditation groups, respectively. The impact of accreditation on timeline improvement was greater for EMS-transported patients than for walk-in patients. (4) Conclusions: EMS-transported patients were more sensitive to the shortened in-hospital delay associated with the initiative, which could exacerbate the existing disparity among patients with different arrival modes.

A modified cardiac triage strategy reduces door to ECG time in patients with ST elevation myocardial infarction. Sci Rep 2021; 11:6358. [PMID: 33737723 PMCID: PMC7973784 DOI: 10.1038/s41598-021-86013-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 03/09/2021] [Indexed: 11/28/2022] Open
Abstract
Timely performing electrocardiography (ECG) is crucial for early detection of ST-elevation myocardial infarction (STEMI). For shortening door-to-ECG time, a chief complaint-based “cardiac triage” protocol comprising (1) raising alert among medical staff with bedside triage tags, and (2) immediate bedside ECG after focused history-taking was implemented at the emergency department (ED) in a single tertiary referral center. All patients diagnosed with STEMI visiting the ED between November 2017 and January 2020 were retrospectively reviewed to investigate the effectiveness of strategy before and after implantation. Analysis of a total of 117 ED patients with STEMI (pre-intervention group, n = 57; post-intervention group, n = 60) showed significant overall improvements in median door-to-ECG time from 5 to 4 min (p = 0.02), achievement rate of door-to-ECG time < 10 min from 45 to 57% (p = 0.01), median door-to-balloon time from 81 to 70 min (p < 0.01). Significant trends of increase in achievement rates for door-to-ECG and door-to-balloon times (p = 0.032 and p = 0.002, respectively) was noted after strategy implementation. The incidences of door-to-ECG time > 10 min for those with initially underestimated disease severity (from 90 to 10%, p < 0.01) and walk-in (from 29.2 to 8.8%, p = 0.04) were both reduced. In conclusion, a chief complaint-based “cardiac triage” strategy successfully improved the quality of emergency care for STEMI patients through reducing delays in diagnosis and treatment.

Abstract
OBJECTIVE To determine the impact of the attention given by emergency medical services teams working in mobile intensive care units (MICU) versus patients arriving at the hospital under their own means with ST-elevation myocardial infarction (STEMI) event in terms of time to reperfusion (TR), mortality at 30 days and six months. METHODS We retrospectively studied 634 consecutive patients with STEMI who underwent primary a percutaneous coronary intervention from January 1st 2015 to December 31st 2018 in a single centre. Depending on the first medical contact patients were classified into two groups, MICU versus walk-in patients. We extracted data on patients' characteristics, symptoms, treatments, times to reperfusion and mortality. RESULTS In our study 634 patients were included, of whom 59.0% were initially attended by the MICU. Differences were seen between the two groups in time delays to the first medical contact (120.0 vs 63.0 min; p < 0.001) and TR (208.0 Vs 150.0 min; p < 0.001). Patients attended by the MICUs presented a shorter ICU and hospital stay. The lowest 30-day mortality rate was observed in MICU group: 9.0% in contrast with 4.5%, p = 0.03; remaining after 6 months. The multivariable analysis showed that the initial attention given by MICU to STEMI patients was a protective agent against mortality [OR: 0.32 (0.11-0.90); p = 0.03]. CONCLUSION Initial attention of the patients with STEMI by doctor-on-board-MICU and available 24 h a day 7 days a week as part of a regional network (CORECAM), was associated with a decrease in the ischemia time, hospital stay and mortality of these patients in our environment.

Abstract
Background Patients with ST-elevation myocardial infarction (STEMI) presenting to percutaneous coronary intervention (PCI)-capable hospitals often experience delays for primary PCI (pPCI). We sought to describe the effect of specific delay intervals and patient/system-level factors on STEMI reperfusion times. Methods We analyzed all consecutive patients with STEMI who presented to 2 PCI-capable hospital emergency departments (EDs) between June 2007 and March 2016 who received successful pPCI. We excluded patients with prehospital cardiac arrest. We compared specific system delay intervals, patient characteristics, and in-hospital outcomes among patients who received timely (first medical contact-device ≤90/≤120 minutes) vs delayed >90/>120 minutes) pPCI. Results Of 1936 patients with STEMI, 1127 (58%) presented directly to a PCI-capable hospital via emergency health services (EHS), 499 (26%) were transferred from the ED of a non-PCI hospital, and 310 (16%) self-presented to the ED of a pPCI-capable hospital. Guideline-recommended reperfusion times were met in 47% of direct-EHS, 42% of transfers, and 33% of self-presenters. Each time interval from first medical contact to device deployment was significantly prolonged in the delayed vs timely reperfusion cohorts across all 3 groups, excepting vascular access time. ED dwell time contributed the most to the difference in median reperfusion time within each group. Time of presentation, comorbidities, and sex were each significantly associated with delayed reperfusion. Within the EHS-direct group, prolonged reperfusion and ED dwell times were significantly associated with increased mortality, major bleeding, and cardiogenic shock. Conclusion Ongoing efforts to identify and reduce ED dwell time and other systemic pPCI delays may improve STEMI outcomes, including mortality.

Abstract
The 12-lead electrocardiogram (ECG) remains the most immediately accessible and widely used initial diagnostic tool for guiding management in patients with suspected myocardial infarction (MI). Although the development of high-sensitivity cardiac troponin assays has improved the rule-in and rule-out and risk stratification of acute MI without ST elevation, the immediate management of the subset of acute MI with acute coronary occlusion depends on integrating clinical presentation and ECG findings. Careful interpretation of the ECG might yield subtle features suggestive of ischemia that might facilitate more rapid triage of patients with subtle acute coronary occlusion or, conversely, in identification of ST-elevation MI mimics (pseudo ST-elevation MI patterns). Our goal in this review article is to consider recent advances in the use of the ECG to diagnose coronary occlusion MIs, including the application of rules that allow MI to be diagnosed on the basis of atypical ECG manifestations. Such rules include the modified Sgarbossa criteria allowing identification of acute MI in left bundle branch block or ventricular pacing, the 3- and 4-variable formula to differentiate normal ST elevation (formerly called early repolarization) from subtle ECG signs of left anterior descending coronary artery occlusion, the differentiation of ST elevation of left ventricular aneurysm from that of acute anterior MI, and the use of lead aVL in the recognition of inferior MI. Improved use of the ECG is essential to improving the diagnosis and appropriate early management of acute coronary occlusion MIs, which will lead to improved outcomes for patients who present with acute coronary syndrome.

Abstract
AIM The influence of the time of arrival at the hospital on the door-to-device (DTD) time has been investigated; however, the influence on the onset-to-device (OTD) time is unclear in ST-segment elevation myocardial infarction (STEMI) patients. The aim of this study was to investigate the relationship between the time of arrival at the hospital and the OTD time in STEMI patients. METHODS We evaluated 377 STEMI patients who underwent primary percutaneous coronary intervention (pPCI) between January 2008 and December 2014. RESULTS During the study period, 222 patients arrived at our hospital between 9 AM and 9 PM (on-hours group) and 155 patients arrived between 9 PM and 9 AM (off-hours group). The DTD time was longer in the off-hours group than in the on-hours group (50.4 vs 39.3 minutes; P<.001), while the OTD time was longer in the on-hours group than in the off-hours group (285.7 vs 184.5 minutes, P<.001). The 30-day mortality and peak creatinine kinase levels were similar between the groups. Transfer from a non-pPCI-capable facility to our hospital was more common in the on-hours group than in the off-hours group (49.1% vs 15.5%, P<.001). The OTD time was shorter in patients who directly visited our hospital than in those who were transferred (172.9 vs 338.5 minutes, P<.001). CONCLUSIONS The OTD time might be markedly longer in STEMI patients who arrive at the hospital during on-hours than in those who arrive at the hospital during off-hours because of the underuse of emergency medical services at STEMI onset.

Abstract
INTRODUCTION The American Heart Association recommends individuals with symptoms suggestive of acute coronary syndrome (ACS) activate the Emergency Medical Services' (EMS) 911 system for ambulance transport to the emergency department (ED), which enables treatment to begin prior to hospital arrival. Despite this recommendation, the majority of patients with symptoms suspicious of ACS continue to self-transport to the ED. The IMMEDIATE AIM study was a prospective study that enrolled individuals who presented to the ED with ischemic symptoms. OBJECTIVES The purpose of this secondary analysis was to determine differences in patients presenting the ED for possible ACS who arrive by ambulance versus self-transport on: 1) time-to-initial hospital electrocardiogram (ECG), 2) presence of ischemic ECG changes, and 3) patient characteristics. METHODS Initial 12-lead ECGs acquired upon patient arrival to the ED were evaluated for ST-elevation, ST-depression, and T-wave inversion. ECG signs of ischemia were analyzed both individually and collapsed into an independent dichotomous variable (ED ECG ischemia yes/no) for statistical analysis. Patient characteristics tested included: gender, age, race, ethnicity, English speaking, living alone, mode of transport, and presenting symptoms (chest pain, jaw pain, shortness of breath, nausea/vomiting, syncope, and clinical history). RESULTS In 1299 patients (mean age 63.9, 46.7% male), 384 (29.6%) patients arrived by ambulance to the ED. The mean time-to-initial ECG was 47minutes for ambulance patients versus 53minutes for self-transport patients (p<0.001). Mode of transport was found to be an independent predictor for time-to-initial ECG controlling for age, gender, and race (p=0.004). There were significantly higher rates of ECG changes of ischemia for patients who arrived by ambulance versus self-transport (p=0.02), and patient characteristics differed by mode of transport to the ED. DISCUSSION Our findings indicate that less than 30% of individuals with symptoms of ACS activate the EMS '911' system for ambulance transport to the ED. Individuals more likely to activate 911 have timelier ECG but higher rates of ischemic changes, specifically ST-depression and T-wave inversion. Individuals least likely to activate 911 are women, younger individuals, Latino ethnicity, live with a significant other, and those experiencing chest or jaw pain.

Physician perceptions and recommendations about pre-hospital emergency medical services for patients with ST-elevation acute myocardial infarction in Abu Dhabi. J Saudi Heart Assoc 2016; 28:7-14. [PMID: 26778900 PMCID: PMC4685199 DOI: 10.1016/j.jsha.2015.05.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2015] [Revised: 05/18/2015] [Accepted: 05/20/2015] [Indexed: 11/22/2022] Open
Abstract
Introduction Physician perceptions about emergency medical services (EMS) are important determinants of improving pre-hospital care for cardiac emergencies. No data exist on physician attitudes towards EMS care of patients with ST-Elevation Myocardial Infarction (STEMI) in the Emirate of Abu Dhabi. Objectives To describe the perceptions towards EMS among physicians caring for patients with STEMI in Abu Dhabi. Methods We surveyed a convenience sample of physicians involved in the care of patients with STEMI (emergency medicine, cardiology, cardiothoracic surgery and intensive care) in four government facilities with 24/7 Primary PCI in the Emirate of Abu Dhabi. Surveys were distributed using dedicated email links, and used 5-point Likert scales to assess perceptions and attitudes to EMS. Results Of 106 physician respondents, most were male (82%), practicing in emergency medicine (47%) or cardiology (44%) and the majority (63%) had been in practice for >10 years. Less than half of the responders (42%) were “Somewhat Satisfied” (35%) or “Very Satisfied” (7%) with current EMS level of care for STEMI patients. Most respondents were “Very Likely” (67%) to advise a patient with a cardiac emergency to use EMS, but only 39% felt the same for themselves or their family. Most responders were supportive (i.e. “Strongly Agree”) of the following steps to improve EMS care: 12-lead ECG and telemetry to ED by EMS (69%), EMS triage of STEMI to PCI facilities (65%), and activation of PCI teams by EMS (58%). Only 19% were supportive of pre-hospital fibrinolytics by EMS. There were no significant differences in the responses among the specialties. Conclusions Most physicians involved in STEMI care in Abu Dhabi are very likely to advise patients to use EMS for a cardiac emergency, but less likely to do so for themselves or their families. Different specialties had concordant opinions regarding steps to improve pre-hospital EMS care for STEMI.

[PMID: 25671039 PMCID: PMC4307715 DOI: 10.5811/westjem.2014.10.23277] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2014] [Revised: 10/01/2014] [Accepted: 10/13/2014] [Indexed: 11/17/2022] Open
Abstract
Introduction The American Heart Association/American College of Cardiology guidelines recommend rapid door-to-electrocardiography (ECG) times for patients with ST-segment elevation myocardial infarction (STEMI). Previous quality improvement research at our institution revealed that we were not meeting this benchmark for walk-in STEMI patients. The objective is to investigate whether simple, directed changes in the emergency department (ED) triage process for potential cardiac patients could decrease door-to-ECG times and secondarily door-to-balloon times. Methods We conducted an interventional study at a large, urban, public teaching hospital from April 2010 to June 2012. All patients who walked into the ED with a confirmed STEMI were enrolled in the study. The primary intervention involved creating a chief complaint-based “cardiac triage” designation that streamlined the evaluation of potential cardiac patients. A secondary intervention involved moving our ECG technician and ECG station to our initial triage area. The primary outcome measure was door-to-ECG time and the secondary outcome measure was door-to-balloon time. Results We enrolled 91 walk-in STEMI patients prior to the intervention period and 141 patients after the invention. We observed statistically significant reductions in door-to-ECG time (43±93 to 30±72 minutes, median 23 to 14 minutes p<0.01), ECG-to-activation time (87±134 to 52±82 minutes, median 43 to 31 minutes p<0.01), and door-to-balloon time (134±146 to 84±40 minutes, median 85 -75 minutes p=0.03). Conclusion By creating a chief complaint-based cardiac triage protocol and by streamlining ECG completion, walk-in STEMI patients are systematically processed through the ED. This is not only associated with a decrease in door-to-balloon time, but also a decrease in the variability of the time sensitive intervals of door-to-ECG and ECG-to-balloon time.
