Effect of Prehospital Digital Electrocardiogram Transmission on Revascularization Delays and Mortality in ST-Elevation Myocardial Infarction Patients: Systematic Review and Meta-Analysis. CJC Open 2024; 6:1199-1206. [PMID: 39525334 PMCID: PMC11544164 DOI: 10.1016/j.cjco.2024.06.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Accepted: 06/09/2024] [Indexed: 11/16/2024] Open
Abstract
Background Prehospital transmission of the 12-lead electrocardiogram (ECG) to the interventional cardiologist has become the standard of care in many ST-elevation myocardial infarction (STEMI) networks but has not been adopted universally. In this systematic review and meta-analysis, we assess the effect of prehospital digital ECG transmission in STEMI patients on door-to-device times, first medical contact-to-device times, and mortality. Methods We performed a systematic review of all English-language studies in MEDLINE, Embase, and CENTRAL (from inception to July 24, 2023), comparing the effect of prehospital digital ECG transmission to that of no ECG transmission in STEMI patients. We performed a random-effects meta-analysis. Results We included 17 observational studies totalling 4306 patients. Door-to-device times were reduced by 33.3 minutes in patients with prehospital digital ECG transmission (95% confidence intervals [CIs] -50.5, -16.2 minutes; P < 0.001; I2 99%). First-medical-contact-to-device time also was reduced with prehospital digital ECG transmission (mean difference, -24.7 minutes; 95% CI -37.1, -12.3 minutes; P < 0.001; I2 96%). Prehospital digital ECG transmissions was associated with a 47% reduction in mortality compared to no prehospital digital ECG transmission (117 of 1322 (8.9%) vs 181 of 1322 (13.7%), odds ratio 0.53, 95% CI 0.40, 0.69; P < 0.001; I2 = 0%). Conclusions Prehospital ECG transmission in STEMI patients, coupled with a systems of care reduced door-to-device times, first-medical-contact-to-device times, and mortality. STEMI networks should consider these findings to advocate for prehospital ECG transmission within their systems of care. Study Registration CRD42024509271 (PROSPERO).

Heart Failure Management through Telehealth: Expanding Care and Connecting Hearts. J Clin Med 2024; 13:2592. [PMID: 38731120 PMCID: PMC11084728 DOI: 10.3390/jcm13092592] [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: 03/28/2024] [Revised: 04/21/2024] [Accepted: 04/25/2024] [Indexed: 05/13/2024] Open
Abstract
Heart failure (HF) is a leading cause of morbidity worldwide, imposing a significant burden on deaths, hospitalizations, and health costs. Anticipating patients' deterioration is a cornerstone of HF treatment: preventing congestion and end organ damage while titrating HF therapies is the aim of the majority of clinical trials. Anyway, real-life medicine struggles with resource optimization, often reducing the chances of providing a patient-tailored follow-up. Telehealth holds the potential to drive substantial qualitative improvement in clinical practice through the development of patient-centered care, facilitating resource optimization, leading to decreased outpatient visits, hospitalizations, and lengths of hospital stays. Different technologies are rising to offer the best possible care to many subsets of patients, facing any stage of HF, and challenging extreme scenarios such as heart transplantation and ventricular assist devices. This article aims to thoroughly examine the potential advantages and obstacles presented by both existing and emerging telehealth technologies, including artificial intelligence.

Telemedical support for prehospital emergency medical service in severe emergencies: an open-label randomised non-inferiority clinical trial. Crit Care 2023; 27:256. [PMID: 37391836 PMCID: PMC10311733 DOI: 10.1186/s13054-023-04545-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Accepted: 06/22/2023] [Indexed: 07/02/2023] Open
Abstract
BACKGROUND A tele-emergency medical service with a remote emergency physician for severe prehospital emergencies may overcome the increasing number of emergency calls and shortage of emergency medical service providers. We analysed whether routine use of a tele-emergency medical service is non-inferior to a conventional physician-based one in the occurrence of intervention-related adverse events. METHODS This open-label, randomised, controlled, parallel-group, non-inferiority trial included all routine severe emergency patients aged ≥ 18 years within the ground-based ambulance service of Aachen, Germany. Patients were randomised in a 1:1 allocation ratio to receive either tele-emergency medical service (n = 1764) or conventional physician-based emergency medical service (n = 1767). The primary outcome was the occurrence of intervention-related adverse events with suspected causality to the group assignment. The trial was registered with ClinicalTrials.gov (NCT02617875) on 30 November 2015 and is reported in accordance with the CONSORT statement for non-inferiority trials. RESULTS Among 3531 randomised patients, 3220 were included in the primary analysis (mean age, 61.3 years; 53.8% female); 1676 were randomised to the conventional physician-based emergency medical service (control) group and 1544 to the tele-emergency medical service group. A physician was not deemed necessary in 108 of 1676 cases (6.4%) and 893 of 1544 cases (57.8%) in the control and tele-emergency medical service groups, respectively. The primary endpoint occurred only once in the tele-emergency medical service group. The Newcombe hybrid score method confirmed the non-inferiority of the tele-emergency medical service, as the non-inferiority margin of - 0.015 was not covered by the 97.5% confidence interval of - 0.0046 to 0.0025. CONCLUSIONS Among severe emergency cases, tele-emergency medical service was non-inferior to conventional physician-based emergency medical service in terms of the occurrence of adverse events.

Abstract
Purpose of Review Through this review, we attempt to explore the role of telemedicine and virtual visits in the field of cardiology pre-COVID-19 and during COVID-19 pandemic, their limitations and their future scope for delivery of care. Recent Findings Telemedicine, which rose to prominence during COVID-19 pandemic, helped not only in reducing the burden on the healthcare system during a time of crisis but also in improving patient outcomes. Patients and physicians also favored virtual visits when feasible. Virtual visits were found to have the potential to be continued beyond the pandemic and play a significant role in patient care alongside conventional face-to-face visits. Summary Although tele-cardiology has proven beneficial in terms of patient care, convenience, and access, it comes with its fair share of limitations-both logistical and medical. Whilst there remains a great scope for improvement in the quality of patient care provided through telemedicine, it has shown the potential to become an integral part of medical practice in the future.

Utility of prehospital electrocardiogram interpretation in ST-segment elevation myocardial infarction utilizing computer interpretation and transmission for interventional cardiologist consultation. Catheter Cardiovasc Interv 2022; 100:295-303. [PMID: 35766040 PMCID: PMC9546148 DOI: 10.1002/ccd.30300] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 02/25/2022] [Accepted: 06/04/2022] [Indexed: 12/26/2022]
Abstract
Objectives We examined the appropriateness of prehospital cardiac catheter laboratory activation (CCL‐A) in ST‐segment elevation myocardial infarction (STEMI) utilizing the University of Glasgow algorithm (UGA) and remote interventional cardiologist consultation. Background The incremental benefit of prehospital electrocardiogram (PH‐ECG) transmission on the diagnostic accuracy and appropriateness of CCL‐A has been examined in a small number of studies with conflicting results. Methods We identified consecutive PH‐ECG transmissions between June 2, 2010 and October 6, 2016. Blinded adjudication of ECGs, appropriateness of CCL‐A, and index diagnoses were performed using the fourth universal definition of MI. The primary outcome was the appropriate CCL‐A rate. Secondary outcomes included rates of false‐positive CCL‐A, inappropriate CCL‐A, and inappropriate CCL nonactivation. Results Among 1088 PH‐ECG transmissions, there were 565 (52%) CCL‐As and 523 (48%) CCL nonactivations. The appropriate CCL‐A rate was 97% (550 of 565 CCL‐As), of which 4.9% (n = 27) were false‐positive. The inappropriate CCL‐A rate was 2.7% (15 of 565 CCL‐As) and the inappropriate CCL nonactivation rate was 3.6% (19 of 523 CCL nonactivations). Reasons for appropriate CCL nonactivation (n = 504) included nondiagnostic ST‐segment elevation (n = 128, 25%), bundle branch block (n = 132, 26%), repolarization abnormality (n = 61, 12%), artefact (n = 72, 14%), no ischemic symptoms (n = 32, 6.3%), severe comorbidities (n = 26, 5.2%), transient ST‐segment elevation (n = 20, 4.0%), and others. Conclusions PH‐ECG interpretation utilizing UGA with interventional cardiologist consultation accurately identified STEMI with low rates of inappropriate and false‐positive CCL‐As, whereas using UGA alone would have almost doubled CCL‐As. The benefits of cardiologist consultation were identifying “masquerading” STEMI and avoiding unnecessary CCL‐As.

[PMID: 35454392 PMCID: PMC9030116 DOI: 10.3390/medicina58040554] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 04/08/2022] [Accepted: 04/14/2022] [Indexed: 01/20/2023]
Abstract
Background and Objectives: The guidelines of the European Society of Cardiology (ESC) recommend the use of telematic methods in the diagnosis of myocardial infarction, allowing for transtelephonic electrocardiography (TTECG) from the emergency scene to centers performing percutaneous coronary interventions (PCI center). It has been proven that such a procedure has a beneficial effect on the survival of patients with ST elevation myocardial infarction (STEMI). Fewer data can be found on the correct use of these methods in everyday clinical practice. The aim of this study was to indicate potential indications and contraindications for the use of the TTECG system, and provide recommendations for proper collaboration between emergency medical systems (EMS) teams and PCI centers. Materials and Methods: The article is a systematic review of cardiological emergencies, with an assessment of indications for the use of the TTECG system. The authors introduced their own grading of the validity of indications for transmission of the TTECG, similar to those used in the official ESC guidelines.: Results:: The authors described individual cardiological emergencies occurring in the practice of EMS, considering specific indications or contraindications for the transmission of the TTECG. The article also discusses individual practical recommendations for proper cooperation between EMS teams and PCI centers in detail. All of the recommendations are compiled in a handy table to facilitate its use in everyday clinical practice. Conclusions: The summary presents a comparison of the realities of the functioning of the telematic support system in Poland in the field of STEMI diagnostics, with the model’s recommendations. The necessity of further educating the members of individual teams included in the network dealing with STEMI treatment was indicated, as well as the necessity of introducing legal regulations sanctioning the functioning of telematic systems in modern medicine.

Abstract
BACKGROUND Developing countries struggle to diagnose and treat ST-segment elevation myocardial infarction (STEMI) patients in a timely manner, and subsequent outcomes are suboptimal. METHODS The Latin America Telemedicine Network (LATIN) functioned between 2013 to present in four countries-Brazil, Colombia, Mexico, and Argentina. A Hub and Spoke platform was developed to expand access to >100 million population for STEMI care. Patients were triaged at spokes that included small clinics and primary health care centers in remote South American locations. Three telemedicine command sites provided immediate 24/7 electrocardiogram diagnosis and teleconsultation of the STEMI process at 355 centers in four countries. RESULTS LATIN Spokes (n = 313) screened up to 30,000 patients per month, and a total of 780,234 patients over the study period. Telemedicine experts diagnosed 8395 (1·1%) with STEMI, of which a total of 3872 (46·1%) were urgently treated at 47 Hubs. A total of 3015 patients (78%) were reperfused with percutaneous coronary intervention. Time-to-telemedicine diagnosis averaged 3·5 min. Average door-to-balloon time improved from 120 to 48 min during the study period and overall STEMI mortality was 5·2%. INTERPRETATION Telemedicine transcends boundaries and enables access to millions of patients for STEMI care. With this initiative, LATIN has created a template for reducing disparities in STEMI management between developed and developing countries.

Abstract
Background The initial care of patients with sepsis is commonly performed by ambulance clinicians (ACs). Early identification, care and treatment are vital for patients with sepsis to avoid adverse outcomes. However, knowledge about how patients with sepsis are assessed in ambulance services (AS) by AC is limited. Therefore, the aim of this study was to explore the meaning of ACs’ lived experiences in assessing patients suspected of having sepsis. Methods A descriptive design with a qualitative approach was used. Fourteen ACs from three Swedish ambulance organizations participated in dyadic and individual semistructured interviews. A thematic analysis based on descriptive phenomenology was performed. Results AC experiences were grouped into four themes: (1) being influenced by previous experience; (2) searching for clues to the severity of the patient’s condition; (3) feeling confident when signs and symptoms were obvious; and (4) needing health-care professionals for support and consultation. Conclusions This study indicates that several factors are important to assessments. ACs needed to engage in an ongoing search for information, discuss the cases with colleagues and reconsider the assessment throughout the entire ambulance mission. A reflective and open stance based on professional knowledge could contribute to recognizing patients with sepsis.

Abstract
This collaborative statement from the International Society for Holter and Noninvasive Electrocardiology/Heart Rhythm Society/European Heart Rhythm Association/Asia Pacific Heart Rhythm Society describes the current status of mobile health ("mHealth") technologies in arrhythmia management. The range of digital medical tools and heart rhythm disorders that they may be applied to and clinical decisions that may be enabled are discussed. The facilitation of comorbidity and lifestyle management (increasingly recognized to play a role in heart rhythm disorders) and patient self-management are novel aspects of mHealth. The promises of predictive analytics but also operational challenges in embedding mHealth into routine clinical care are explored.

Abstract
OBJECTIVES To review the implementation strategy from a research project towards routine care of a comprehensive mobile physician-staffed prehospital telemedicine system. The objective is to evaluate the implementation process and systemic influences on emergency medical service (EMS) resource utilisation. DESIGN Retrospective pre-post implementation study. SETTING Two interdisciplinary projects and the EMS of a German urban region. INTERVENTIONS Implementation of a full-scale prehospital telemedicine system. ENDPOINTS Descriptive evaluation of the implementation strategy. Primary endpoint: ground-based and helicopter-based physician staffed emergency missions before and after implementation. RESULTS The first research project revealed positive effects on guideline adherence and patient safety in two simulation studies, with feasibility demonstrated in a clinical study. After technical optimisation, safety and positive effects were demonstrated in a multicentre trial. Routine care in the city of Aachen, Germany was conducted stepwise from April 2014 to March 2015, including modified dispatch criteria. Systemic parameters of all EMS assignments between pre-implementation (April 2013 to March 2014) and post implementation (April 2015 to March 2016): on-scene EMS physician operations decreased from 7882/25 187 missions (31.3%) to 6360/26 462 (24.0%), p<0.0001. The need for neighbouring physician-staffed units dropped from 234/25 187 (0.93%) to 119/26 462 (0.45%), p<0.0001, and the need for helicopter EMS from 198/25 187 (0.79%) to 100/26 462 (0.38%), p<0.0001. In the post implementation period 2347 telemedical interventions were conducted, with 26 462 emergency missions (8.87%). CONCLUSION A stepwise implementation strategy allowed transfer from the project phase to routine care. We detected a reduced need for conventional on-scene physician care by ground-based and helicopter-based EMS, but cannot exclude unrecognised confounders, including modified dispatch criteria and possible learning effects. This creates the potential for increased availability of EMS physicians for life-threatening emergencies by shifting physician interventions from conventional to telemedical care.

Abstract
This collaborative statement from the International Society for Holter and Noninvasive Electrocardiology/ Heart Rhythm Society/ European Heart Rhythm Association/ Asia Pacific Heart Rhythm Society describes the current status of mobile health ("mHealth") technologies in arrhythmia management. The range of digital medical tools and heart rhythm disorders that they may be applied to and clinical decisions that may be enabled are discussed. The facilitation of comorbidity and lifestyle management (increasingly recognized to play a role in heart rhythm disorders) and patient self-management are novel aspects of mHealth. The promises of predictive analytics but also operational challenges in embedding mHealth into routine clinical care are explored.

Predictors of Hospital Mortality in Patients with Acute Coronary Syndrome Complicated by Cardiogenic Shock. SENSORS (BASEL, SWITZERLAND) 2021; 21:969.

Abstract
As demonstrated by earlier studies, pre-hospital triage with trans-telephonic electrocardiogram (TTECG) and direct referral for catheter therapy shows great value in the management of out-of-hospital chest pain emergencies. It does not only improve in-hospital mortality in ST-segment elevation myocardial infarction, but it has also been identified as an independent predictor of higher in-hospital survival rate. Since TTECG-facilitated triage shortens both transport time and percutaneous coronary intervention (PCI)-related procedural time intervals, it was hypothesized that even high-risk patients with acute coronary syndrome (ACS) and cardiogenic shock (CS) might also benefit from TTECG-based triage. Here, we decided to examine our database for new triage- and left ventricular (LV) function-related parameters that can influence in-hospital mortality in ACS complicated by CS. ACS patients were divided into two groups, namely, (1) hospital death patients (n = 77), and (2) hospital survivors (control, n = 210). Interestingly, TTECG-based consultation and triage of CS and ACS patients were confirmed as significant independent predictors of lower hospital mortality risk (odds ratio (OR) 0.40, confidence interval (CI) 0.21-0.76, p = 0.0049). Regarding LV function and blood chemistry, a good myocardial reperfusion after PCI (high area at risk (AAR) blush score/AAR LV segment number; OR 0.85, CI 0.78-0.98, p = 0.0178) and high glomerular filtration rate (GFR) value at the time of hospital admission (OR 0.97, CI 0.96-0.99, p = 0.0042) were the most crucial independent predictors of a decreased risk of in-hospital mortality in this model. At the same time, a prolonged time interval between symptom onset and hospital admission, successful resuscitation, and higher peak creatine kinase activity were the most important independent predictors for an increased risk of in-hospital mortality. In ACS patients with CS, (1) an early TTECG-based teleconsultation and triage, as well as (2) good myocardial perfusion after PCI and a high GFR value at the time of hospital admission, appear as major independent predictors of a lower in-hospital mortality rate.

Abstract
BACKGROUND The efficacy of telemedicine in reducing delay times and short-term adverse clinical outcomes in patients with ST segment elevation myocardial infarction (STEMI) during the coronavirus disease 2019 (COVID-19) pandemic is unclear. This study compared outcomes in patients with STEMI who had percutaneous coronary intervention (PCI) and the use of a telemedicine app from August 2019 to March 2020 at a single center in Beijing, China. MATERIAL AND METHODS A total of 243 patients with STEMI who underwent PCI were consecutively enrolled and divided into 2 groups according to the date, before or after the pandemic. The 2 groups were further divided into patients who used the app for consulting and those who did not. RESULTS The time from symptom onset to calling an ambulance (SCT), door to balloon time (DTB), and total ischemia time (TIT) were significantly prolonged in patients after the pandemic. Patients who used the app had shorter SCT, DTB, and TIT before and after the pandemic compared to those who did not. Adverse clinical outcomes were significantly higher after compared with before the pandemic, despite the incidence rate of stroke, any revascularization, and stent thrombosis. However, there was no significant difference in short-term adverse clinical outcomes between patients who used the app and those who did not before and after the pandemic. CONCLUSIONS Telemedicine reduced the delay time of STEMI patients during the COVID-19 pandemic. The difference in short-term adverse clinical outcomes was not statistically significant between patients who used the app and those who did not.

Abstract
Mobile health (mHealth) technologies are modernizing medicine by affording greater patient engagement, monitoring, outreach, and health-care delivery. The cardiopulmonary fields have led the integration of mHealth into clinical practice and research. mHealth technologies in these areas include smartphone applications, wearable devices, and handheld devices, among others, and provide real-time monitoring of numerous important physiological measurements and other key parameters. Use of mHealth-compatible devices has increased in recent years, and age and socioeconomic gaps of ownership are narrowing. These tools provide physicians and researchers with a better understanding of an individual's health and well-being. mHealth interventions have shown utility in the prevention, monitoring, and management of atrial fibrillation, heart failure, and myocardial infarction. With the growing prevalence of cardiopulmonary disease, mHealth technologies may become a more essential element of care within and outside of traditional health-care settings. mHealth is continuously developing as a result of technologic advancements and better understandings of mHealth utility. However, there is little regulation on the mHealth platforms available for commercial use and even fewer guidelines on implementing evidence-based practices into mHealth technologies. Online security is another challenge and necessitates development in data collection infrastructure to manage the extraordinary volume of patient data. Continued research on long-term implications of mHealth technology and the integration of effective interventions into clinical practice is required.

Abstract
OBJECTIVE To investigate, in a simulator-based prospective study, whether telemedical support improves quality of emergency first response (performance) by medical non-professionals to being non-inferior to medical professionals. SETTING In a simulated offshore wind power plant, duos (teams) of offshore engineers and teams of paramedics conducted the primary survey of a simulated patient. PARTICIPANTS 38 offshore engineers and 34 paramedics were recruited by the general email invitation. INTERVENTION Teams (randomised by lot) were supported by transmission technology and a remote emergency physician in Berlin. OUTCOME MEASURES From video recordings, performance (17 item checklist) and required time (up to 15 min) were quantified by expert rating for analysis. Differences were analysed using two-sided exact Mann-Whitney U tests for independent measures, non-inferiority was analysed using Schuirmann one-sided test. The significance level of 5 % was Holm-Bonferroni adjusted in each family of pairwise comparisons. RESULTS Nine teams of engineers with, nine without, nine teams of paramedics with and eight without support completed the task. Two experts quantified endpoints, insights into rater dependence were gained. Supported engineers outperformed unsupported engineers (p<0.01), insufficient evidence was found for paramedics (p=0.11). Without support, paramedics outperformed engineers (p<0.01). Supported engineers' performance was non-inferior (at one item margin) to that by unsupported paramedics (p=0.03). Supported groups were slower than unsupported groups (p<0.01). CONCLUSIONS First response to medical emergencies in offshore wind farms with substantially delayed professional care may be improved by telemedical support. Future work should test our result during additional scenarios and explore interdisciplinary and ecosystem aspects of this support. TRIAL REGISTRATION NUMBER DRKS00014372.

Abstract
INTRODUCTION The transtelephonic electrocardiogram has been shown to have a great value in the management of out-of-hospital chest pain emergencies. In our previous study it not only improved the pre-hospital medical therapy and time to intervention, but also the in-hospital mortality in ST-segment elevation myocardial infarction. It was hypothesised that the higher in-hospital survival rate could be due to improved transtelephonic electrocardiogram-based pre-hospital management (electrocardiogram interpretation and teleconsultation) and consequently, better coronary perfusion of patients at the time of hospital admission. To test this hypothesis, our database of ST-segment elevation myocardial infarction patients was evaluated retrospectively for predictors (including transtelephonic electrocardiogram) that may influence in-hospital survival. METHODS AND RESULTS The ST-segment elevation myocardial infarction patients were divided into two groups, namely (a) hospital death patients (n = 49) and (b) hospital survivors (control, n = 726). Regarding pre-hospital medical management, the transtelephonic electrocardiogram-based triage (odds ratio 0.48, confidence interval 0.25-0.92, p = 0.0261) and the administration of optimal pre-hospital medical therapy (acetylsalicylic acid and/or clopidogrel and glycoprotein IIb/IIIa inhibitor) were the most important independent predictors for a decreased risk in our model. At the same time, age, acute heart failure (Killip class >2), successful pre-hospital resuscitation and total occlusion of the infarct-related coronary artery before percutaneous coronary intervention were the most important independent predictors for an increased risk of in-hospital mortality. DISCUSSION In ST-segment elevation myocardial infarction patients, (a) an early transtelephonic electrocardiogram-based teleconsultation and triage, (b) optimal pre-hospital antithrombotic medical therapy and (c) the patency and better perfusion of the infarct-related coronary artery on hospital admission are important predictors of a lower in-hospital mortality rate.

Abstract
Background: In ST-segment elevation myocardial infarction (STEMI) patients treated with percutaneous coronary intervention, direct transport from the scene to the catheterisation laboratory bypassing the emergency department has been shown to shorten times to reperfusion. The aim of this study was to investigate the effects of emergency department bypass on mortality in both haemodynamically stable and unstable STEMI patients. Methods: The analysis is based on a large cohort of STEMI patients prospectively included in the German multicentre Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction (FITT-STEMI) trial. Results: Out of 13,219 STEMI patients who were brought directly from the scene by emergency medical service transportation and were treated with percutaneous coronary intervention, the majority were transported directly to the catheterisation laboratory bypassing the emergency department (n=6740, 51% with emergency department bypass). These patients had a significantly lower in-hospital mortality than their counterparts with no emergency department bypass (6.2% vs. 10.0%, P<0.0001). The reduced mortality related to emergency department bypass was observed in both stable (n=11,594, 2.8% vs. 3.8%, P=0.0024) and unstable patients presenting with cardiogenic shock (n=1625, 36.3% vs. 46.2%, P<0.0001). Regression models adjusted for the Thrombolysis In Myocardial Infarction (TIMI) risk score consistently confirmed a significant and independent predictive effect of emergency department bypass on survival in the total study population (odds ratio 0.64, 95% confidence interval 0.56–0.74, P<0.0001) and in the subgroup of shock patients (OR 0.69, 95% CI 0.54–0.88, P=0.0028). Conclusion: In STEMI patients, emergency department bypass is associated with a significant reduction in mortality, which is most pronounced in patients presenting with cardiogenic shock. Our data encourage treatment protocols for emergency department bypass to improve the survival of both haemodynamically stable patients and, in particular, unstable patients.

Abstract
In 2003 an article on the future of prehospital emergency medicine in Germany was published in the journal Der Anaesthesist. Emergency medicine in Germany, which at that time was almost exclusively defined as prehospital emergency rescue, has evolved and now in-hospital domains have increasingly moved into the focus. At that time, the primary goal was to connect prehospital management with a smooth transition to hospital admission and further care in the hospital and to further optimize the rescue chain from the actual emergency through to causative treatment. Now after 15 years, the authors have critically assessed the development postulated in 2003 and reevaluated it. Which aspects could be developed further and become firmly established, what is still open and which questions in preclinical and clinical emergency treatment of the population will occupy us in the coming 15 years? With a critical eye to the past, the present contribution aims to capture the essential and new topics and open questions and provide a fresh perspective for the future of emergency medicine. Regulation at the state level or even lower levels of government often stand in contrast to more sweeping and economically effective approaches at the federal level. Prehospital emergency medicine in Germany is on the whole well-positioned with respect to facilities and personnel; however, as far as the economic situation and the utilization of available systems are concerned, there is still substantial room for improvement.

Abstract
Health informatics applications reduce time intervals in acute coronary syndromes, but their impact on guideline adherence is unknown. This pre-post intervention study compared guideline adherence between telemedically supported (n = 101, April 2014-July 2015) and conventional on-scene care (n = 120, January 2014-March 2014) in acute coronary syndrome. A multivariate logistic regression was performed for dependent variables: adverse events 0 versus 0, p = NA; electrocardiogram 101 versus 120, p = NA; acetylic salicylic acid 91 versus 102, p = 0.21; heparin 92 versus 112, p = 0.99; morphine 96 versus 107, p = 0.33; oxygen 83 versus 102, p = 0.92; glyceroltrinitrate 55 versus 90, p = 0.038; correct destination: 100 versus 119, p = 1.0. The time from ambulance arrival to hospital arrival was prolonged with telemedicine: 48.7 ± 11 min versus 35.5 ± 8.1 min, p < 0.001. Guideline adherence showed no differences except for glyceroltrinitrate. Prolonged time requirements are critical, though explainable. However, this approach enables a timely and high-quality backup strategy if only paramedics are on-scene.

Abstract
IntroductionField identification of ST-elevation myocardial infarction (STEMI) and advanced hospital notification decreases first-medical-contact-to-balloon (FMC2B) time. A recent study in this system found that electrocardiogram (ECG) transmission following a STEMI alert was frequently unsuccessful.HypothesisInstituting weekly test ECG transmissions from paramedic units to the hospital would increase successful transmission of ECGs and decrease FMC2B and door-to-balloon (D2B) times. METHODS This was a natural experiment of consecutive patients with field-identified STEMI transported to a single percutaneous coronary intervention (PCI)-capable hospital in a regional STEMI system before and after implementation of scheduled test ECG transmissions. In November 2014, paramedic units began weekly test transmissions. The mobile intensive care nurse (MICN) confirmed the transmission, or if not received, contacted the paramedic unit and the department's nurse educator to identify and resolve the problem. Per system-wide protocol, paramedics transmit all ECGs with interpretation of STEMI. Receiving hospitals submit patient data to a single registry as part of ongoing system quality improvement. The frequency of successful ECG transmission and time to intervention (FMC2B and D2B times) in the 18 months following implementation was compared to the 10 months prior. Post-implementation, the time the ECG transmission was received was also collected to determine the transmission gap time (time from ECG acquisition to ECG transmission received) and the advanced notification time (time from ECG transmission received to patient arrival). RESULTS There were 388 patients with field ECG interpretations of STEMI, 131 pre-intervention and 257 post-intervention. The frequency of successful transmission post-intervention was 73% compared to 64% prior; risk difference (RD)=9%; 95% CI, 1-18%. In the post-intervention period, the median FMC2B time was 79 minutes (inter-quartile range [IQR]=68-102) versus 86 minutes (IQR=71-108) pre-intervention (P=.3) and the median D2B time was 59 minutes (IQR=44-74) versus 60 minutes (IQR=53-88) pre-intervention (P=.2). The median transmission gap was three minutes (IQR=1-8) and median advanced notification time was 16 minutes (IQR=10-25). CONCLUSION Implementation of weekly test ECG transmissions was associated with improvement in successful real-time transmissions from field to hospital, which provided a median advanced notification time of 16 minutes, but no decrease in FMC2B or D2B times.

Abstract
Major disparities exist between developed and developing countries in the management of acute myocardial infarction (AMI). These pronounced differences result in significantly increased morbidity and mortality from AMI in different regions of the world. Lack of infrastructure, insurance, facilities, and skilled personnel are the major constraints. Primary percutaneous coronary intervention has revolutionized the treatment of AMI; however, its global use is limited by the listed constraints. Telemedicine provides an efficient methodology that can hugely increase access and accuracy of AMI management.

Abstract
Prehospital hypertensive emergencies and urgencies are common, but evidence is lacking. Telemedically supported hypertensive emergencies and urgencies were prospectively collected (April 2014-March 2015) and compared retrospectively with a historical control group of on-scene physician care in the emergency medical service of Aachen, Germany. Blood pressure management and guideline adherence were evaluated. Telemedical (n=159) vs conventional (n=172) cases: blood pressure reductions of 35±24 mm Hg vs 44±23 mm Hg revealed a group effect adjusted for baseline differences (P=.0006). Blood pressure management in categories: no reduction 6 vs 0 (P=.0121); reduction ≤25% (recommended range) 113 vs 110 patients (P=.2356); reduction >25% to 30% 13 vs 29 (0.020); reduction >30% 12 vs 16 patients (P=.5608). The telemedical approach led to less pronounced blood pressure reductions and a tendency to improved guideline adherence. Telemedically guided antihypertensive care may be an alternative to conventional care especially for potentially underserved areas.

Abstract
Acute pain is a common reason for summoning emergency medical services (EMS). Yet in several countries the law restricts opioid-based analgesia administration to physicians. Telemedical support of paramedics is a novel approach to enable timely treatment under the guidance of a physician. In this retrospective observational study, conducted in the EMS of Aachen, Germany, the analgesic quality and occurrence of adverse events were compared between telemedically-supported paramedics (July-December, 2014) and a historical control group (conventional on-scene EMS physicians; January-March, 2014). Inclusion criteria: pain (initial numerical rating scale (NRS) ≥5) and/or performed analgesia. Telemedically-assisted analgesia was performed in 149 patients; conventional analgesia in 199 control cases. Teleconsultation vs. control: Initial NRS scores were 8.0 ± 1.5 and 8.1 ± 1.7. Complete NRS documentation was carried out in 140/149 vs. 130/199 cases, p < 0.0001. NRS scores were reduced by 4.94 ± 2.01 and 4.84 ± 2.28 (p = 0.5379), leading to mean NRS scores at emergency room arrival of 3.1 ± 1.7 vs. 3.3 ± 1.9 (p = 0.5229). No severe adverse events occurred in either group. Clinically relevant pain reduction was achieved in both groups. Thus, the concept of remote physician-based telemedically-delegated analgesia by paramedics is effective compared to analgesia by on-scene EMS physicians and safe.

Abstract
Telemedicine has deeply innovated the field of emergency cardiology, particularly the treatment of acute myocardial infarction. The ability to record an ECG in the early prehospital phase, thus avoiding any delay in diagnosing myocardial infarction with direct transfer to the cath-lab for primary angioplasty, has proven to significantly reduce treatment times and mortality. This consensus document aims to analyse the available evidence and organizational models based on a support by telemedicine, focusing on technical requirements, education, and legal aspects.

Abstract
Background Increasing numbers of emergency calls, shortages of Emergency Medical Service (EMS), physicians, prolonged emergency response times and regionally different quality of treatment by EMS physicians require improvement of this system. Telemedical solutions have been shown to be beneficial in different emergency projects, focused on specific disease patterns. Our previous pilot studies have shown that the implementation of a holistic prehospital EMS teleconsultation system, between paramedics and experienced tele-EMS physicians, is safe and feasible in different emergency situations. We aim to extend the clinical indications for this teleconsultation system. We hypothesize that the use of a tele-EMS physician is noninferior regarding the occurrence of system-induced patient adverse events and superior regarding secondary outcome parameters, such as the quality of guideline-conforming treatment and documentation, when compared to conventional EMS-physician treatment. Methods/design Three thousand and ten patients will be included in this single-center, open-label, randomized controlled, noninferiority trial with two parallel arms. According to the inclusion criteria, all emergency cases involving adult patients who require EMS-physician treatment, excluding life-threatening cases, will be randomly assigned by the EMS dispatching center into two groups. One thousand five hundred and five patients in the control group will be treated by a conventional EMS physician on scene, and 1505 patients in the intervention group will be treated by paramedics who are concurrently instructed by the tele-EMS physicians at the teleconsultation center. The primary outcome measure will include the rate of treatment-specific adverse events in relation to the kind of EMS physician used. The secondary outcome measures will record the specific treatment-associated quality indicators. Discussion The evidence underlines the better quality of service using telemedicine networks between medical personnel and medical experts in prehospital emergency care, as well as in other medical areas. The worldwide unique EMS teleconsultation system in Aachen has been optimized and evaluated in pilot studies and subsequently integrated into routine use for a broad spectrum of indications. It has enabled prompt, safe and efficient patient treatment with optimized use of the “resource” EMS physician. There is, however, a lack of evidence as to whether the advantages of the teleconsultation system can be replicated in wider-ranging EMS-physician indications (excluding life-threatening emergency calls).

Abstract
Among the wide range of medical specialties in which telemedicine has been successfully applied, cardiology can be considered as one of the most important fields of application. Through the transmission of clinical data and the electrocardiogram, telecardiology allows access to a real-time assessment (teleconsultation) without any need to travel for both patient and cardiologist. This review discusses the impact of telecardiology in different clinical settings of application. Pre-hospital telecardiology has proved to be useful either in the clinical management of remote patients with acute coronary syndrome or in supporting the decision-making process of general practitioners. In the setting of in-hospital telecardiology, most of the applications refer to real-time echocardiography transmissions between rural small hospitals and tertiary care centres, particularly for the diagnosis or exclusion of congenital heart disease in newborns. Finally, many trials show that post-hospital telecardiology improves outcomes and reduces re-admissions or outpatient contacts in patients with heart failure, arrhythmias or implantable devices.

Abstract
BACKGROUND A shorter time to treatment has been shown to be associated with lower mortality rates in acute myocardial infarction (AMI). Several strategies have been adopted with the aim to reduce any delay in diagnosis of AMI: pre-hospital triage with telemedicine is one of such strategies. We therefore aimed to measure the real effect of pre-hospital triage with telemedicine in case of AMI in a meta-analysis study. METHODS We performed a meta-analysis of non-randomized studies with the aim to quantify the exact reduction of time to treatment achieved by pre-hospital triage with telemedicine. Data were pooled and compared by relative time reduction and 95% C.I.s. A meta-regression analysis was performed in order to find possible predictors of shorter time to treatment. RESULTS Eleven studies were selected and finally evaluated in the study. The overall relative reduction of time to treatment with pre-hospital triage and telemedicine was -38/-40% (p<0.001). Absolute time reduction was significantly correlated to time to treatment in the control groups (p<0.001), while relative time reduction was independent. A non-significant trend toward shorter relative time reductions was observed over years. CONCLUSIONS Pre-hospital triage with telemedicine is associated with a near halved time to treatment in AMI. The benefit is larger in terms of absolute time to treatment reduction in populations with larger delays to treatment.

Abstract
BACKGROUND Prehospital treatment of acute coronary syndrome (ACS) in German emergency medical services (EMSs) is reserved for EMS physicians due to legal issues. OBJECTIVE The objective of this prospective, interventional, multicenter trial was to evaluate the quality of telemedically-delegated therapy and the possible complications in patients with ACS. METHODS After approval by the ethics committee and trial registration, a one-year study phase was started in August 2012 with 5 ambulances, telemedically equipped and staffed with paramedics, in 4 German EMS districts. The paramedics could contact an EMS-physician-staffed telemedicine center. After initiation of an audio connection, real-time data transmission was automatically established. If required, 12-lead electrocardiogram (ECG) and still pictures could be sent. Video was streamed from inside each ambulance. All drugs, including opioids, were delegated to the paramedics based on standardized, predefined algorithms. To compare telemedically-delegated medication and treatment in ACS cases with regular EMS missions, a matched pair analysis with historical controls was performed. RESULTS Teleconsultation was performed on 150 patients having a cardiovascular emergency. In 39 cases, teleconsultation was started due to suspected ACS. No case had a medical complication. Correct handling of 12-lead ECG was performed equally between the groups (study group, n=38 vs control group, n=39, P>.99). There were no differences in correct handling of intravenous administration of acetylsalicylic acid, heparin, or morphine between both the groups (study group vs control group): acetylsalicylic acid, n=31 vs n=33, P=.73; unfractionated heparin, n=34 vs n=33, P>.99; morphine, n=29 vs n=27, P=.50. The correct handling of oxygen administration was significantly higher in the study group (n=29 vs n=18, P=.007). CONCLUSIONS Telemedical delegation of guideline conform medication and therapy by paramedics in patients with ACS and was found to be feasible and safe. The quality of guideline-adherent therapy was not significantly different in both the groups except for the correct administration of oxygen, which was significantly higher in the study group.

Abstract
Access to health care in Canada's rural areas is a challenge. The Unité de Coordination Clinique des Services Préhospitaliers d'Urgence (UCCSPU) is a telemedicine program designed to improve health care in the Chaudiere-Appalaches and Quebec City regions of Canada. Remote medical services are provided by nurses and by an emergency physician based in a clinical unit at the Alphonse-Desjardins Community Health and Social Services Center. The interventions were developed to meet two objectives. The first is to enhance access to quality health care. To this end, Basic Life Support paramedics and nurses were taught interventions outside of their field of expertise. Prehospital electrocardiograms were used to remotely diagnose ST segment elevation myocardial infarction and to monitor patients who were en route by ambulance to the nearest catheterization facility or emergency department. Basic Life Support paramedics received extended medical authorization that allowed them to provide opioid analgesia via telemedicine physician orders. Nurses from community health centres without physician coverage were able to request medical assistance via a video telemedicine system. The second objective is to optimize medical resources. To this end, remote death certifications were implemented to avoid unnecessary transport of deceased persons to hospitals. This paper presents the telemedicine program and some results.

Abstract
Introduction Telemedical concepts in emergency medical services (EMS) lead to improved process times and patient outcomes, but their technical performance has thus far been insufficient; nevertheless, the concept was transferred into EMS routine care in Aachen, Germany. This study evaluated the system's technical performance and compared it to a precursor system. Methods The telemedicine system was implemented on seven ambulances and a teleconsultation centre staffed with experienced EMS physicians was established in April 2014. Telemedical applications included mobile vital data, 12-lead, picture transmission and video streaming from inside the ambulances. The tele-EMS physician filled in a questionnaire regarding the technical performance of the applications, background noise and assessed clinical values of the transmitted pictures and videos after each mission between 15 May 2014-15 October 2014. Results Teleconsultation was established during 539 emergency cases. In 83% of the cases ( n = 447), only the paramedics and the tele-EMS physician were involved. Transmission success rates ranged from 98% (audio connection) to 93% (12-lead electrocardiogram (ECG) transmission). All functionalities, except video transmission, were significantly better than the pilot project ( p < 0.05). Severe background noise was detected to a lesser extent ( p = 0.0004) and the clinical value of the pictures and videos were considered significantly more valuable. Discussion The multifunctional system is now sufficient for routine use and is the most reliable mobile emergency telemedicine system compared to other published projects. Dropouts were due to user errors and network coverage problems. These findings enable widespread use of this system in the future, reducing the critical time intervals until medical therapy is started.

Analgesia by telemedically supported paramedics compared with physician-administered analgesia: A prospective, interventional, multicentre trial. Eur J Pain 2016; 20:1176-84.

Abstract
BACKGROUND In German emergency medical services (EMS), the analgesia is restricted to physicians. In this prospective, interventional, multicentre trial, complications with and quality of telemedically delegated analgesia were evaluated. METHODS If prehospital analgesia was necessary, five telemedically equipped paramedic ambulances from four different districts could consult a telemedicine centre. Analgesics were delegated based on a predefined algorithm. Telemedically assisted cases were compared with local historical regular EMS missions using matched pairs. The primary outcome was the frequency of therapeutic complications (respiratory/circulatory insufficiency, allergic reactions). Secondary outcomes were quality of analgesia (11-point numerical rating scale, NRS) and the frequency of nausea/vomiting. RESULTS Analgesia was necessary in 106 telemedically assisted missions. In 23 cases, the telemedical procedure was used until an EMS physician arrived. Of the remaining 83 cases, 80 could be matched to comparable controls. Complications did not occur in either the study group or the control group (0 vs. 0; p = N/A). Complete NRS documentation was noted in 65/80 (study group) and 32/80 (control group) cases (p < 0.0001). Adequate initial pain reduction (quality indicator: reduction of NRS ≥ 2 points or NRS < 5 at end of mission) occurred in 61/65 versus 31/32 cases (p = 1.0); NRS reduction during mission was 3.78 ± 2.0 versus 4.38 ± 2.2 points (p = 0.0159). Nausea and vomiting occurred with equal frequency in both groups. CONCLUSIONS Telemedical delegation of analgesics to paramedics was safe and led to a pain reduction superior to the published minimum standard in both groups. The documentation quality was better in the telemedicine group. WHAT DOES THIS STUDY ADD?: Little is known about the safety and quality of prehospital analgesia carried out by emergency medical services (EMS). Beside potential quality problems, in some countries meaningful pain reduction is limited by legal regulations that allow only physicians to administer analgesics. This first multicentre prospective trial for telemedically delegated analgesia demonstrates that remote analgesia is possible and safe and retains equivalent analgesic quality compared with that administered by onsite EMS physicians.

Abstract
Cardiovascular disease is one of the main fields of application for telemedicine, with benefits in almost all areas in the continuum of cardiovascular disease. The greatest impact has been shown in the early diagnosis of cardiovascular disease, in second consultation, between non-cardiologist and cardiologist and between cardiologists, and in follow-up and secondary prevention of cardiovascular disease. At present, the main area of implementation for telemedicine in cardiovascular disease is represented by pre-hospital triage, with telemedicine electrocardiogram in acute myocardial infarction. Significant results have also been achieved in the second opinion consultation of pediatric subjects with congenital cardiovascular disease, home-monitoring and the management of patients affected by chronic heart failure or with an implanted device. However, there is significant room for further improvement in delivering telemedicine assistance even in 'very-remote' populations, such as detainees, patients in developing countries or in underdeveloped areas of developed countries.

Abstract
BACKGROUND The demographic change and an increasing multimorbidity of patients represent increasing challenges for the adequate prehospital treatment of emergency patients. The incorporation of supplementary telemedical concepts and systems can lead to an improved guideline-conform treatment. Beneficial evidence of telemedical procedures is only known for isolated disease patterns; however, no mobile telemedical concept exists which is suitable for use in the wide variety of different clinical situations. AIM This article presents a newly developed and evaluated total telemedical concept (TemRas) that encompasses organizational, medical and technical components. The use of intelligent and robust communication technology and the implementation of this add-on system allows the telemedical support of the rescue service for all emergencies. METHODS After development of the telemedical rescue assistance system, which includes organizational, medical and technical components, a telemedical centre and six ambulances in five different districts in North-Rhine Westphalia were equipped with this new tool. During the evaluation phase of 1 year in the routine emergency medical service the rate of complications as well as differences between urban and rural areas were analyzed with respect to different target parameters. RESULTS Between August 2012 and July 2013 a total of 401 teleconsultations were performed during emergency missions and 24 during secondary interhospital transfers. No complications due to teleconsultation were observed. The mean duration (±SD) of teleconsultations was longer in rural areas than in urban areas with 28.6±12.0 min vs. 25.5±11.1 min (p < 0.0001). In 63.2% of these missions administration of medications was delegated to the ambulance personnel (52.0% urban vs. 73.6% rural, p < 0.0001). The severity of ailments corresponded to scores of III and VI in the National Advisory Committee for Aeronautics (NACA) classification. CONCLUSION Emergency medical care of patients with support by a telemedical system is technically feasible, safe for the patient and allows medical treatment independent of spatial availability of a physician in different emergency situations.

Abstract
BACKGROUND The rapid international expansion of telemedicine reflects the growth of technological innovations. This technological advancement is transforming the way in which patients can receive health care. MATERIALS AND METHODS The study was conducted in Poland, at the Department of Cardiology of the Regional Hospital of Louis Rydygier in Torun. The researchers analyzed the delay in the treatment of patients with acute coronary syndrome. The study was conducted as a survey and examined 67 consecutively admitted patients treated invasively in a two-stage transport system. Data were analyzed statistically. RESULTS Two-stage transportation does not meet the timeframe guidelines for the treatment of patients with acute myocardial infarction. Intervals for the analyzed group of patients were statistically significant (p < 0.0001). CONCLUSIONS Direct transportation of the patient to a reference center with interventional cardiology laboratory has a significant impact on reducing in-hospital delay in case of patients with acute coronary syndrome. PERSPECTIVES This article presents the results of two-stage transportation of the patient with acute coronary syndrome. This measure could help clinicians who seek to assess time needed for intervention. It also shows how time from the beginning of pain in chest is important and may contribute to patient disability, death or well-being.

Abstract
BACKGROUND There were over 5,000,000 ambulance dispatches during 2010 in Japan, and the time for transportation has been increasing, it took over 37 minutes from dispatch to the hospitals. A way to reduce transportation time by ambulance is to shorten the time of searching for an appropriate facility/hospital during the prehospital phase. Although the information system of medical institutions and emergency medical service (EMS) was established in 2003 in Saga Prefecture, Japan, it has not been utilized efficiently. The Saga Prefectural Government renewed the previous system in an effort to make it the real-time support system that can efficiently manage emergency demand and acceptance for the first time in Japan in April 2011. OBJECTIVE The objective of this study was to evaluate if the new system promotes efficient emergency transportation for critically ill patients and provides valuable epidemiological data. METHODS The new system has provided both emergency personnel in the ambulance, or at the scene, and the medical staff in each hospital to be able to share up-to-date information about available hospitals by means of cloud computing. All 55 ambulances in Saga are equipped with tablet computers through third generation/long term evolution networks. When the emergency personnel arrive on the scene and discern the type of patient's illness, they can search for an appropriate facility/hospital with their tablet computer based on the patient's symptoms and available medical specialists. Data were collected prospectively over a three-year period from April 1, 2011 to March 31, 2013. RESULTS The transportation time by ambulance in Saga was shortened for the first time since the statistics were first kept in 1999; the mean time was 34.3 minutes in 2010 (based on administrative statistics) and 33.9 minutes (95% CI 33.6-34.1) in 2011. The ratio of transportation to the tertiary care facilities in Saga has decreased by 3.12% from the year before, 32.7% in 2010 (regional average) and 29.58% (9085/30,709) in 2011. The system entry completion rate by the emergency personnel was 100.00% (93,110/93,110) and by the medical staff was 46.11% (14,159/30,709) to 47.57% (14,639/30,772) over a three-year period. Finally, the new system reduced the operational costs by 40,000,000 yen (about $400,000 US dollars) a year. CONCLUSIONS The transportation time by ambulance was shorter following the implementation of the tablet computer in the current support system of EMS in Saga Prefecture, Japan. The cloud computing reduced the cost of the EMS system.

Abstract
BACKGROUND Over the last decade, significant advances in ST-elevation myocardial infarction (STEMI) workflow have resulted in most hospitals reporting door-to-balloon (D2B) times within the 90 min standard. Few programs have been enacted to systematically attempt to achieve routine D2B within 60 min. We sought to determine whether 24-hr in-house catheterization laboratory coverage via an In-House Interventional Team Program (IHIT) could achieve D2B times below 60 min for STEMI and to compare the results to the standard primary percutaneous coronary intervention (PCI) approach. METHODS An IHIT program was established consisting of an attending interventional cardiologist, and a catheterization laboratory team present in-hospital 24 hr/day. For all consecutive STEMI patients, we compared the standard primary PCI approach during the two years prior to the program (group A) to the initial 20 months of the IHIT program (group B), and repeated this analysis for only CMS-reportable patients. The D2B process was analyzed by calculating workflow intervals. The primary endpoint was D2B process times, and secondary endpoints included in-hospital and 6-month cardiovascular outcomes and resource utilization. RESULTS An IHIT program for STEMI resulted in significant reductions across all treatment intervals with an overall 57% reduction in D2B time, and an absolute reduction in mean D2B time of 71 min. There were no differences pre- and post-program implementation in regard to individual or composite components of in-hospital cardiovascular outcomes; however at 6 months, there was a reduction in cardiovascular rehospitalization after program implementation (30 vs. 5%, P < 0.01). The IHIT program resulted in a significant reduction in length-of-stay (LOS) (90 ± 102 vs. 197 ± 303 hr, P = 0.02), and critical care time (54 ± 97 vs. 149 ± 299 hr, P = 0.02). CONCLUSIONS Availability of an in-house 24-hr STEMI team significantly decreased reperfusion time and led to improved clinical outcomes and a shorter LOS for PCI-treated STEMI patients.

Telemedicine for cardiovascular disease continuum: A position paper from the Italian Society of Cardiology Working Group on Telecardiology and Informatics. Int J Cardiol 2015; 184:452-458. [PMID: 25755064 DOI: 10.1016/j.ijcard.2015.02.023] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2014] [Revised: 02/02/2015] [Accepted: 02/21/2015] [Indexed: 11/20/2022]
Abstract
Telemedicine is the provision of health care services, through the use of information and communication technology, in situations where the health care professional and the patient, or 2 health care professionals, are not in the same location. It involves the secure transmission of medical data and information, through text, sound, images, or other forms needed for the prevention, diagnosis, treatment, and follow-up of a patient. First data on implementation of telemedicine for the diagnosis and treatment of acute myocardial infarction date from more than 10 years ago. Telemedicine has a potential broad application to the cardiovascular disease continuum and in many branches of cardiology, at least including heart failure, ischemic heart disease and arrhythmias. Telemedicine might have an important role as part of a strategy for the delivery of effective health care for patients with cardiovascular disease. In this document the Working Group on Telecardiology and Informatics of the Italian Society of Cardiology intends to remark some key-points regarding potential benefit achievable with the implementation of telemedicine support in the continuum of cardiovascular disease.

Abstract
The right person in the right place and at the right time is not always possible; telemedicine offers the potential to give audio and visual access to the appropriate clinician for patients. Advances in information and communication technology (ICT) in the area of video-to-video communication have led to growth in telemedicine applications in recent years. For these advances to be properly integrated into healthcare delivery, a regulatory framework, supported by definitive high-quality research, should be developed. Telemedicine is well suited to extending the reach of specialist services particularly in the pre-hospital care of acute emergencies where treatment delays may affect clinical outcome. The exponential growth in research and development in telemedicine has led to improvements in clinical outcomes in emergency medical care. This review is part of the LiveCity project to examine the history and existing applications of telemedicine in the pre-hospital environment. A search of electronic databases including Medline, Excerpta Medica Database (EMBASE), Cochrane, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) for relevant papers was performed. All studies addressing the use of telemedicine in emergency medical or pre-hospital care setting were included. Out of a total of 1,279 articles reviewed, 39 met the inclusion criteria and were critically analysed. A majority of the studies were on stroke management. The studies suggested that overall, telemedicine had a positive impact on emergency medical care. It improved the pre-hospital diagnosis of stroke and myocardial infarction and enhanced the supervision of delivery of tissue thromboplasminogen activator in acute ischaemic stroke. Telemedicine presents an opportunity to enhance patient management. There are as yet few definitive studies that have demonstrated whether it had an effect on clinical outcome.

Feasibility and efficacy of a remote real-time wireless ECG monitoring and stimulation system for management of ventricular arrhythmia in rabbits with myocardial infarction. Exp Ther Med 2014; 8:201-206. [PMID: 24944622 PMCID: PMC4061215 DOI: 10.3892/etm.2014.1693] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2013] [Accepted: 04/03/2014] [Indexed: 11/21/2022] Open
Abstract
The purpose of this study was to explore the feasibility of continuous remote monitoring, and the induction and termination of malignant ventricular arrhythmias (VAs) by a novel implantable electronic cardiovascular device (IECD) system in rabbits with myocardial infarction (MI). The IECD was implanted and MI was induced by ligation of the left anterior descending coronary artery in 20 adult rabbits. Internet-based remote electrocardiogram (ECG) monitoring and ventricular stimulation were conducted in remote locations with internet access. The voltage amplitudes of the stimulation signals were recorded synchronously by remote and surface ECG. Programmed stimulation with regular stimuli and regular stimuli with an added extra stimulus were performed prior to and following the MI surgery to induce and terminate VAs. IECD implantation and MI surgery, as well as qualified remote and bidirectional signal communications between the implanted IECD and extracorporeal system, were successfully achieved in 18 rabbits. The voltage of the stimulation signals recorded by the remote and surface ECGs showed a good correlation with the stimulation current (remote ECG, r=0.972 and surface ECG, r=0.988; P<0.001). Sustained ventricular tachycardia (VT) was induced in five rabbits (5/20, 25%) prior to MI induction and in 12 rabbits (12/16, 75%) following MI induction. Of the 17 induced VTs, 16 were successfully terminated by remote ventricular stimulation. The novel IECD system provides qualified remote wireless ECG monitoring and possesses the potential to induce and terminate VAs by remote ventricular pacing in this rabbit model of MI. Thus, this model of MI may be used to test the efficacy of novel drugs and devices for the management of VAs.

Abstract
We assessed an early notification system using smartphones to reduce door-to-balloon times (DTBT) in ST-elevation myocardial infarction (STEMI). Text page alarms were sent to cardiologists for all patients presenting with chest pain or an equivalent in the emergency department before acquisition of an electrocardiogram (ECG). A total of 210 patients (with mean age of 59 years) were investigated (109 in the intervention group and 101 in a control group from the previous two-year period). The primary outcome, the DTBT, was significantly lower in the intervention group compared to the control group (55.0 and 92.5 min, respectively, P < 0.001). In a secondary analysis, the length of hospital stay was also significantly less. However, there was no significant improvement in all-cause one-year mortality. Early text page alarms using smartphones were effective in reducing the DTBT, but had a limited effect on clinical outcome.

From door-to-balloon time to contact-to-device time: predictors of achieving target times in patients with ST-elevation myocardial infarction. Clin Cardiol 2014; 37:389-94. [PMID: 24700343 DOI: 10.1002/clc.22278] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2014] [Revised: 03/02/2014] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND The 2013 American College of Cardiology Foundation/American Heart Association ST-segment elevation myocardial infarction (STEMI) guidelines have shifted focus from door-to-balloon (D2B) time to the time from first medical contact to device activation (contact-to-device time [C2D] ). HYPOTHESIS This study investigates the impact of prehospital wireless electrocardiogram transmission (PHT) on reperfusion times to assess the impact of the new guidelines. METHODS From January 2009 to December 2012, data were collected on STEMI patients who received percutaneous coronary interventions; 245 patients were included for analysis. The primary outcome was median C2D time in the PHT group and the secondary outcome was D2B time. RESULTS Prehospital wireless electrocardiogram transmission was associated with reduced C2D times vs no PHT: 80 minutes (interquartile range [IQR], 64-94) vs 96 minutes (IQR, 79-118), respectively, P < 0.0001. The median D2B time was lower in the PHT group vs the no-PHT group: 45 minutes (IQR, 34-56) vs 63 minutes (IQR, 49-81), respectively, P < 0.0001. Multivariate analysis showed PHT to be the strongest predictor of a C2D time of <90 minutes (odds ratio: 3.73, 95% confidence interval: 1.65-8.39, P = 0.002). Female sex was negatively predictive of achieving a C2D time <90 minutes (odds ratio: 0.23, 95% confidence interval: 0.07-0.73, P = 0.01). CONCLUSIONS In STEMI patients, PHT was associated with significantly reduced C2D and D2B times and was an independent predictor of achieving a target C2D time. As centers adapt to the new guidelines emphasizing C2D time, targeting a shorter D2B time (<50 minutes) is ideal to achieve a C2D time of <90 minutes.
