Assessing North Texas Regional Trauma Handoffs: A Multicenter Mixed-Methods Needs Assessment.

INTRODUCTION: Trauma video review of Emergency Medical Services (EMS) handoffs demonstrates frequent problems including interruptions and incomplete information transfer. This study aimed to perform a regional needs assessment of handoff perceptions and expectations to guide future standardization efforts. METHODS: A multidisciplinary team of trauma providers through consensus building created an anonymous survey which was then distributed through the North Central Texas Trauma Regional Advisory Council and four regional level-1 trauma institutions. Qualitative data underwent content analysis; quantitative data are presented with descriptive statistics. RESULTS: Survey responses (n = 249) were submitted by trauma nurses (38%), EMS (24%), emergency physicians (14%), and trauma physicians (13%). Median overall handoff quality was rated well (4, scale 1-5) despite some variability between hospitals (3, scale 1-5). The top five most important handoff details were the same for both stable and unstable patients: primary mechanism, blood pressure, heart rate, Glasgow Coma Scale, and location of injuries. While providers felt neutral about the data order, the vast majority supported immediate bed transfer and primary survey in unstable patients. The majority of receiving providers report interrupting handoff at least once (78%); and 66% of EMS clinicians found interruptions disruptive. Content analysis revealed top priority categories for improvement: environment, communication, information relayed, team dynamics, and flow of care. CONCLUSION: Although our data demonstrated satisfaction and concordance with respect to the EMS handoff, 84% of EMS clinicians reported some to high amounts of variability across institutions. Gaps in the development of standardized handoffs identified include exposure, education, and enforcement of these protocols.

Review of Emergency Medical Services Vulnerability to High Consequence Infectious Disease in the United States.

Purpose: Emergency medical services (EMS) responders are a group of medically skilled professionals who perform a wide range of essential medical services within a community including emergency response, patient transport, and mobile integrated healthcare. The proper functioning of the EMS system is paramount to the well-being of the medical system and public health. The intent of this paper is to review current EMS standards and practice to determine the danger a high consequence infectious disease (HCID) may pose to these healthcare workers and the community. Areas Addressed: Through the review of EMS practice several areas were identified as vulnerabilities to the EMS network. These vulnerabilities consisted of the lack of standardized licensing practice, inconsistent medical direction, and the inability to properly implement the use of personal protective equipment (PPE). The compounding of these vulnerabilities allows for HCIDs to pose a serious threat to EMS personnel with the possibility of devastating and crippling the EMS infrastructure within the US. Discussion: The vulnerabilities identified must be addressed both to protect EMS providers and to enhance the resilience of the US healthcare system. Ways to address the identified vulnerabilities should focus on improving the EMS curriculum and increasing minimum levels of education for first responders. Targeting minimum education and training standards could be the most effect method of reducing the dangers of HCIDs to EMS systems.

Health Care Project Improvement Design: Proficiency Among University Faculty.

The purpose was to measure faculty members': (1) knowledge of quality improvement and patient safety (QIPS), (2) attitudes and beliefs about their own QI skills, and (3) self-efficacy toward participating in, leading, and teaching QIPS. Faculty completed an online survey. Questions assessed demographic and academic characteristics, knowledge, attitudes/beliefs, and self-efficacy. Knowledge was measured using the Quality Improvement Knowledge Assessment Tool-Revised (QIKAT-R). Participants provided free-text responses to questions about clinical scenarios. Almost half of participants (n = 236) self-reported that they were moderately or extremely comfortable with QIPS skills. Few were very (20%) or most (15%) comfortable teaching QIPS. Ninety-one participants attempted the QIKAT-R, and 78 participants completed it. The mean score was 16.6 (SD = 5.6). Despite positive attitudes and beliefs about their own QIPS skills, study results demonstrate a general lack of knowledge among surveyed faculty members. Faculty development efforts are needed to improve proficiency in participating, leading, and teaching QIPS projects.

Rationale and Strategies for Development of an Optimal Bundle of Management for Cardiac Arrest.

OBJECTIVES: To construct a highly detailed yet practical, attainable roadmap for enhancing the likelihood of neurologically intact survival following sudden cardiac arrest. DESIGN SETTING AND PATIENTS: Population-based outcomes following out-of-hospital cardiac arrest were collated for 10 U.S. counties in Alaska, California, Florida, Ohio, Minnesota, Utah, and Washington. The 10 identified emergency medical services systems were those that had recently reported significant improvements in neurologically intact survival after introducing a more comprehensive approach involving citizens, hospitals, and evolving strategies for incorporating technology-based, highly choreographed care and training. Detailed inventories of in-common elements were collated from the ten 9-1-1 agencies and assimilated. For reference, combined averaged outcomes for out-of-hospital cardiac arrest occurring January 1, 2017, to February 28, 2018, were compared with concurrent U.S. outcomes reported by the well-established Cardiac Arrest Registry to Enhance Survival. INTERVENTIONS: Most commonly, interventions and components from the ten 9-1-1 systems consistently included extensive public cardiopulmonary resuscitation training, 9-1-1 system-connected smart phone applications, expedited dispatcher procedures, cardiopulmonary resuscitation quality monitoring, mechanical cardiopulmonary resuscitation, devices for enhancing negative intrathoracic pressure regulation, extracorporeal membrane oxygenation protocols, body temperature management procedures, rapid cardiac angiography, and intensive involvement of medical directors, operational and quality assurance officers, and training staff. MEASUREMENTS AND MAIN RESULTS: Compared with Cardiac Arrest Registry to Enhance Survival (n = 78,704), the cohorts from the 10 emergency medical services agencies examined (n = 2,911) demonstrated significantly increased likelihoods of return of spontaneous circulation (mean 37.4% vs 31.5%; p < 0.001) and neurologically favorable hospital discharge, particularly after witnessed collapses involving bystander cardiopulmonary resuscitation and shockable cardiac rhythms (mean 10.7% vs 8.4%; p < 0.001; and 41.6% vs 29.2%; p < 0.001, respectively). CONCLUSIONS: The likelihood of neurologically favorable survival following out-of-hospital cardiac arrest can improve substantially in communities that conscientiously and meticulously introduce a well-sequenced, highly choreographed, system-wide portfolio of both traditional and nonconventional approaches to training, technologies, and physiologic management. The commonalities found in the analyzed systems create a compelling case that other communities can also improve out-of-hospital cardiac arrest outcomes significantly by conscientiously exploring and adopting similar bundles of system organization and care.

The impact of increased chest compression fraction on survival for out-of-hospital cardiac arrest patients with a non-shockable initial rhythm.

OBJECTIVE: We evaluated the effect of chest compression fraction (CCF) on survival to hospital discharge and return of spontaneous circulation (ROSC) in out-of-hospital cardiac arrest (OHCA) patients with non-shockable rhythms. METHODS: This is a retrospective analysis (completed in 2016) of a prospective cohort study which included OHCA patients from ten U.S. and Canadian sites (Resuscitation Outcomes Consortium Epistry and PRIMED study (2007-2011)). We included all OHCA victims of presumed cardiac aetiology, not witnessed by emergency medical services (EMS), without automated external defibrillator shock prior to EMS arrival, receiving > 1 min of CPR with CPR process measures available, and initial non-shockable rhythm. We measured CCF using the first 5 min of electronic CPR records. RESULTS: Demographics of 12,928 adult patients were: mean age 68; male 59.9%; public location 8.5%; bystander witnessed 35.2%; bystander CPR 39.3%; median interval from 911 to defibrillator turned on 10 min:04 s; initial rhythm asystole 64.8%, PEA 26.0%, other non-shockable 9.2%; compression rate 80-120/min (69.1%); median CCF 74%; ROSC 25.6%; survival to hospital discharge 2.4%. Adjusted odds ratio (OR); 95% confidence intervals (95%CI) of survival for each CCF category were: 0-40% (2.00; 1.16, 3.32); 41-60% (0.83; 0.54, 1.24); 61-80% (1.02; 0.77, 1.35); and 81-100% (reference group). Adjusted (OR; 95%CI) of ROSC for each CCF category were: 0-40% (1.02; 0.79, 1.30); 41-60% (0.83; 0.72, 0.95); 61-80% (0.85; 0.77, 0.94); and 81-100% (reference group). CONCLUSIONS: We observed an incremental benefit from higher CCF on the incidence of ROSC, but not survival, among non-shockable OHCA patients with CCF higher than 40%.

Annotated Guidance and Recommendations for the Role and Actions of Emergency Medical Services Systems in the Current Opioid and Drug-Related Epidemics.

BACKGROUND: The U.S. and worldwide death toll from opioids and other drugs has accelerated, rivaling all other causes of premature death. Emergency medical services (EMS) now has an evolving role in providing solutions. METHODS: EMS medical directors from the majority of the largest U.S. cities and global counterparts met to share/compile an inventory of best practices derived from their respective high-volume experiences in jurisdictions with >114 million residents combined. In turn, they created a consensus guideline document for the purposes of information-sharing among themselves and other interested parties. RESULTS: The group concluded that EMS personnel have evolving training needs with respect to new medical care challenges, but they also recommended that agencies have a special place within the collective of those hoping to provide solutions to the public health crisis of addiction and drug-related epidemics. In addition to intervening in real-time overdose events, it was recommended that they partner with other key stakeholders to develop mechanisms to end the repetitive cycle of emergency rescue followed by an almost immediate return to addictive behaviors. EMS providers should be trained to optimally communicate, refer, and direct the affected individuals to appropriate resources that will provide viable and evidence-based pathways directed toward long-term recovery. CONCLUSIONS: Beyond a need to update acute medical rescue practices and improved assessment techniques, EMS providers should also learn to optimally communicate, encourage, and even participate in facilitating management continuity for the affected individuals by identifying and using the appropriate resources that will provide viable, evidence-based pathways toward sustained recovery.

Ranking the Attributes of Effective Disaster Responders and Leaders.

OBJECTIVE: To investigate the relative importance of 10 attributes identified in prior studies as essential for effective disaster medical responders and leaders. METHODS: Emergency and disaster medical response personnel (N=220) ranked 10 categories of disaster worker attributes in order of their importance in contributing to the effectiveness of disaster responders and leaders. RESULTS: Attributes of disaster medical leaders and responders were rank ordered, and the rankings differed for leaders and responders. For leaders, problem-solving/decision-making and communication skills were the highest ranked, whereas teamwork/interpersonal skills and calm/cool were the highest ranked for responders. CONCLUSIONS: The 10 previously identified attributes of effective disaster medical responders and leaders include personal characteristics and general skills in addition to knowledge of incident command and disaster medicine. The differences in rank orders of attributes for leaders and responders suggest that when applying these attributes in personnel recruitment, selection, and training, the proper emphasis and priority given to each attribute may vary by role.

Confirming the Clinical Safety and Feasibility of a Bundled Methodology to Improve Cardiopulmonary Resuscitation Involving a Head-Up/Torso-Up Chest Compression Technique.

OBJECTIVES: Combined with devices that enhance venous return out of the brain and into the thorax, preclinical outcomes are improved significantly using a synergistic bundled approach involving mild elevation of the head and chest during cardiopulmonary resuscitation. The objective here was to confirm clinical safety/feasibility of this bundled approach including use of mechanical cardiopulmonary resuscitation provided at a head-up angle. DESIGN: Quarterly tracking of the frequency of successful resuscitation before, during, and after the clinical introduction of a bundled head-up/torso-up cardiopulmonary resuscitation strategy. SETTING: 9-1-1 response system for a culturally diverse, geographically expansive, populous jurisdiction. PATIENTS: All 2,322 consecutive out-of-hospital cardiac arrest cases (all presenting cardiac rhythms) were followed over 3.5 years (January 1, 2014, to June 30, 2017). INTERVENTIONS: In 2014, 9-1-1 crews used LUCAS (Physio-Control Corporation, Redmond, WA) mechanical cardiopulmonary resuscitation and impedance threshold devices for out-of-hospital cardiac arrest. After April 2015, they also 1) applied oxygen but deferred positive pressure ventilation several minutes, 2) solidified a pit-crew approach for rapid LUCAS placement, and 3) subsequently placed the patient in a reverse Trendelenburg position (~20°). MEASUREMENTS AND MAIN RESULTS: No problems were observed with head-up/torso-up positioning (n = 1,489), but resuscitation rates rose significantly during the transition period (April to June 2015) with an ensuing sustained doubling of those rates over the next 2 years (mean, 34.22%; range, 29.76-39.42%; n = 1,356 vs 17.87%; range, 14.81-20.13%, for 806 patients treated prior to the transition; p < 0.0001). Outcomes improved across all subgroups. Response intervals, clinical presentations and indications for attempting resuscitation remained unchanged. Resuscitation rates in 2015-2017 remained proportional to neurologically intact survival (~35-40%) wherever tracked. CONCLUSIONS: The head-up/torso-up cardiopulmonary resuscitation bundle was feasible and associated with an immediate, steady rise in resuscitation rates during implementation followed by a sustained doubling of the number of out-of-hospital cardiac arrest patients being resuscitated. These findings make a compelling case that this bundled technique will improve out-of-hospital cardiac arrest outcomes significantly in other clinical evaluations.

Gender-based outcome differences for emergency department presentation ofnon-STEMI acute coronary syndrome.

BACKGROUND: It is known that women generally have worse mortality outcomes than men with regards to ST-segment elevation myocardial infarction. However, less is known about contemporary gender differences in non-STEMI acute coronary syndrome, particularly those presenting to emergency departments within a regionalized system of care with standardized protocols. METHODS: Retrospective registry data from 2010 to 2016 were examined from the North Texas Mission: Lifeline system of care, representing 33 hospitals around the Dallas Texas metropolitan area. We explored gender-based differences using multivariate logistic regression model, controlling for patient's age, baseline condition, and hospital factors. RESULTS: There were 16,861 patients who presented directly to emergency departments with NSTEMI, and 6513 (38.6%) were women. At baseline, women were older (68.04 vs. 63.7 years, p < 0.001) and presented with history of prior cardiovascular disease more often than men. Women had higher unadjusted in-hospital mortality rates than men (4.8% vs. 3.9%, p < 0.001), which persisted after controlling for patient age, comorbidities, and hospital factors. Women also had 23 min longer ED lengths of stay (p < 0.001) and were much less likely to receive an early invasive strategy (diagnostic coronary angiography within 24 h of arrival) than men (47.0% vs 54.4%, p < 0.001). CONCLUSION: Emergency department NSTEMI protocols should consider potential gender disparities that exist for women. Overall, women had worse outcomes, which persist even in an urban system of care with standardized protocols.

Dallas MegaShelter Medical Operations Response to Hurricane Harvey.

On August 25, 2017, Hurricane Harvey made landfall near Corpus Christi, Texas. The ensuing unprecedented flooding throughout the Texas coastal region affected millions of individuals.1 The statewide response in Texas included the sheltering of thousands of individuals at considerable distances from their homes. The Dallas area established large-scale general population sheltering as the number of evacuees to the area began to amass. Historically, the Dallas area is one familiar with "mega-sheltering," beginning with the response to Hurricane Katrina in 2005.2 Through continued efforts and development, the Dallas area had been readying a plan for the largest general population shelter in Texas.

Sex-Based Differences in Discharge Disposition and Outcomes for ST-Segment Elevation Myocardial Infarction Patients Within a Regional Network.

BACKGROUND: It is known that women with ST-segment elevation myocardial infarction (STEMI) have higher mortality in comparison to men. While the reasons for this sex-based difference are not completely understood, biologic differences and disparities in care have been implicated. Whether these differences persist within an urban, regional STEMI system of care with defined protocols is unclear. Our objective was to explore sex-related effects in outcomes in a large regional system of care. MATERIALS AND METHODS: Data were drawn from a regional subset of the National Cardiovascular Data Registry for 33 hospitals in and around Dallas County, Texas from 2010 to 2015. We explored adjusted differences between women and men for discharge disposition, door to balloon (D2B), total ischemic time (TIS), length of stay, and in-hospital mortality rates. RESULTS: Multivariate regressions to control for confounding factors, including age, D2B, and TIS, were significantly prolonged in women compared to men (D2B 58 vs. 54 minutes; TIS 206 vs. 178 minutes; both p < 0.001). Length of stay was 0.45 median days longer. Women were also much less likely to survive at discharge than men [odds ratio (OR): 0.63; 95% confidence interval (CI): 0.52-0.76]. Most notably, they were much less likely to be discharged to home than men (88% vs. 92%, p < 0.001). CONCLUSIONS: In this study, we found that sex-based disparities persist for both cardiovascular outcomes and discharge disposition, even in a modern regionalized system of care.

Obesity, Treatment Times, and Cardiovascular Outcomes After ST-Elevation Myocardial Infarction: Findings From Mission: Lifeline North Texas.

BACKGROUND: With increasing rates of obesity and its link with cardiovascular disease, there is a need for better understanding of the obesity-outcome relationship. This study explores the association between categories of obesity with treatment times and mortality for patients experiencing ST-segment elevation myocardial infarction. METHODS AND RESULTS: We examined 8725 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention and used regression models to analyze the relationship between 6 categories of body mass index with key door-to-balloon time, total ischemic time, and in-hospital mortality. We relied on data from the Mission: Lifeline North Texas program, consisting of 33 percutaneous coronary intervention-capable hospitals in 6 counties surrounding Dallas, Texas. Data were extracted from the National Cardiovascular Data Registry for each participating hospital. Of the samples, 76% were overweight or obese. Comparing the univariate differences between the normal-weight group and the pooled sample, we observed a U-shaped association between body mass index and both mortality and door-to-balloon times. The most underweight and severely obese had the highest mortality and median door-to-balloon time, respectively. These differences persisted after multivariate adjustments for door-to-balloon time, but not for mortality. CONCLUSIONS: Extremely obese patients have longer treatment time delays than other body mass index categories. However, this did not extend to significant differences in mortality in the multivariate models. We conclude that clinicians should incorporate body mass assessments into their diagnosis and treatment plans to mitigate observed disparities.

Interorganizational Collaboration in Emergency Cardiovascular Care.

BACKGROUND: Interorganizational collaboration management theory contends that cooperation between distinct but related organizations can yield innovation and competitive advantage to the participating organization. Yet, it is unclear if a multi-institutional collaborative can improve quality outcomes across communities. METHODS: We developed a large regional collaborative network of 15 hospitals and 24 emergency medical service agencies surrounding Dallas, Texas, and collected patient-level data on treatment times for acute myocardial infarctions. Using a pre-/posttest research design, we applied median tests of differences to explore outcome changes between groups and over the 6-year period, using data extracted from participating hospital electronic health records. RESULTS: We analyzed temporal trends and changes in treatment times for 2302 patients with ST-elevation myocardial infarction between the pre- and posttest groups. We found a statistically significant 19-minute median reduction in the key outcome metric (total ischemic time, the time difference between the patient's first reported symptoms and the definitive opening of the artery). This represents a 10.8% community-wide improvement over time. CONCLUSIONS: Interorganizational collaboration focused on quality improvement can impact population health across a community. This study provides a basis for broader understanding and participation by health care organizations in multi-institutional community change efforts.

Reperfusion injury protection during Basic Life Support improves circulation and survival outcomes in a porcine model of prolonged cardiac arrest.

OBJECTIVE: Ischemic postconditioning (PC) using three intentional pauses at the start of cardiopulmonary resuscitation (CPR) improves outcomes after cardiac arrest in pigs when epinephrine (epi) is used before defibrillation. We hypothesized PC, performed during basic life support (BLS) in the absence of epinephrine, would reduce reperfusion injury and enhance 24h functional recovery. DESIGN: Prospective animal investigation. SETTING: Animal laboratory SUBJECTS: Female farm pigs (n=46, 39±1kg). INTERVENTIONS: Protocol A: After 12min of ventricular fibrillation (VF), 28 pigs were randomized to four groups: (A) Standard CPR (SCPR), (B) active compression-decompression CPR with an impedance threshold device (ACD-ITD), (C) SCPR+PC (SCPR+PC) and (D) ACD-ITD CPR+PC. Protocol B: After 15min of VF, 18 pigs were randomized to ACD-ITD CPR or ACD-ITD+PC. The BLS duration was 2.75min in Protocol A and 5min in Protocol B. Following BLS, up to three shocks were delivered. Without return of spontaneous circulation (ROSC), CPR was resumed and epi (0.5mg) and defibrillation delivered. The primary end point was survival without major adverse events. Hemodynamic parameters and left ventricular ejection fraction (LVEF) were also measured. Data are presented as mean±SEM. MEASUREMENTS AND MAIN RESULTS: Protocol A: ACD-ITD+PC (group D) improved coronary perfusion pressure after 3min of BLS versus the three other groups (28±6, 35±7, 23±5 and 47±7 for groups A, B, C, D respectively, p=0.05). There were no significant differences in 24h survival between groups. PROTOCOL B: LVEF 4h post ROSC was significantly higher with ACD-ITD+PC vs ACD-ITD alone (52.5±3% vs. 37.5±6.6%, p=0.045). Survival rates were significantly higher with ACD-ITD+PC vs. ACD-ITD alone (p=0.027). CONCLUSIONS: BLS using ACD-ITD+PC reduced post resuscitation cardiac dysfunction and improved functional recovery after prolonged untreated VF in pigs. PROTOCOL NUMBER: 12-11.

Characteristics of Effective Disaster Responders and Leaders: A Survey of Disaster Medical Practitioners.

OBJECTIVE: To identify key attributes of effective disaster/mass casualty first responders and leaders, thereby informing the ongoing development of a capable disaster health workforce. METHODS: We surveyed emergency response practitioners attending a conference session, the EMS State of the Science: A Gathering of Eagles. We used open-ended questions to ask participants to describe key characteristics of successful disaster/mass casualty first responders and leaders. RESULTS: Of the 140 session attendees, 132 (94%) participated in the survey. All responses were categorized by using a previously developed framework. The most frequently mentioned characteristics were related to incident command/disaster knowledge, teamwork/interpersonal skills, performing one's role, and cognitive abilities. Other identified characteristics were related to communication skills, adaptability/flexibility, problem solving/decision-making, staying calm and cool under stress, personal character, and overall knowledge. CONCLUSIONS: The survey findings support our prior focus group conclusion that important characteristics of disaster responders and leaders are not limited to the knowledge and skills typically included in disaster training. Further research should examine the extent to which these characteristics are consistently associated with actual effective performance of disaster response personnel and determine how best to incorporate these attributes into competency models, processes, and tools for the development of an effective disaster response workforce. (Disaster Med Public Health Preparedness. 2016;page 1 of 4).

The BVM Effect. An overview of studies assessing airway management in out-of-hospital cardiac arrest.

Numerous studies addressing airway management in OHCA have shown a strong association between improved survival with treatment using BVM alone rather than with advanced airways. This BVM effect appears to persist despite variations in geographical region, patient population, and CPR quality. The underlying cause of this phenomenon remains to be determined. Of note, the survival benefit with BVM alone vs. advanced airways doesn't appear in the pediatric population in the papers reviewed by the authors. The authors recommend that a prospective randomized study be conducted in order to explore this finding and to attempt to determine its causation.
