A dignitary medicine curriculum developed using a modified Delphi methodology.

BACKGROUND: Dignitary medicine is an emerging field of training that involves the specialized care of diplomats, heads of state, and other high-ranking officials. In an effort to provide guidance on training in this nascent field, we convened a panel of experts in dignitary medicine and using the Delphi methodology, created a consensus curriculum for training in dignitary medicine. METHODS: A three-round Delphi consensus process was performed with 42 experts in the field of dignitary medicine. Predetermined scores were required for an aspect of the curriculum to advance to the next round. The scores on the final round were used to determine the components of the curriculum. Scores below the threshold to advance were dropped in the subsequent round. RESULTS: Our panel had a high degree of agreement on the required skills needed to practice dignitary medicine, with active practice in a provider's baseline specialty, current board certification, and skills in emergency care and resuscitation being the highest rated skills dignitary medicine physicians need. Skills related to vascular and emergency ultrasound and quality improvement were rated the lowest in the Delphi analysis. No skills were dropped from consideration. CONCLUSIONS: The results of our work can form the basis of formal fellowship training, continuing medical education, and publications in the field of dignitary medicine. It is clear that active medical practice and knowledge of resuscitation and emergency care are critical skills in this field, making emergency medicine physicians well suited to practicing dignitary medicine.

On-demand synchronous audio video telemedicine visits are cost effective.

INTRODUCTION: Claims data raises the possibility that on demand telemedicine programs might increase new utilization, offsetting the cost benefits described in some retrospective analyses. We prospectively evaluated the cost of a synchronous audio-video on-demand telemedicine taking into account both what patients would have done instead of the telemedicine visit as well as the care patients received after the visit. MATERIALS AND METHODS: We conducted a prospective observational study of patients who received care from an on-demand telemedicine program. At the time of the visit, we surveyed patients about the alternative care that would have been requested, if they had not done the telemedicine visit. We also obtained information following the visit about what further care was received. Using cost data derived from the literature we performed a sensitivity analysis to determine the cost impact of the on-demand telemedicine visit. RESULTS: There were 650 patients enrolled with a mean age of 37 who were 68% female; 74% had their care concerns resolved on the telemedicine visit; only 16% would have "done nothing" if they had not done the telemedicine visit, representing possible new utilization. Net cost savings per telemedicine visit was calculated to range from $19-$121 per visit. CONCLUSIONS: In our on-demand telemedicine program, we found the majority of health concerns could be resolved in a single consultation and new utilization was infrequent. Synchronous audio-video telemedicine consults resulted in short-term cost savings by diverting patients from more expensive care settings.

Geographic Modeling to Quantify the Impact of Primary and Comprehensive Stroke Center Destination Policies.

BACKGROUND AND PURPOSE: We evaluated the impact of a primary stroke center (PSC) destination policy in a major metropolitan city and used geographic modeling to evaluate expected changes for a comprehensive stroke center policy. METHODS: We identified suspected stroke emergency medical services encounters from 1/1/2004 to 12/31/2013 in Philadelphia, PA. Transport times were compared before and after initiation of a PSC destination policy on 10/3/2011. Geographic modeling estimated the impact of bypassing the closest hospital for the closest PSC and for the closest comprehensive stroke center. RESULTS: There were 2 326 943 emergency medical services runs during the study period, of which 15 099 had a provider diagnosis of stroke. Bypassing the closest hospital for a PSC was common before the official policy and increased steadily over time. Geographic modeling suggested that bypassing the closest hospital in favor of the closest PSC adds a median of 3.1 minutes to transport time. Bypassing to the closest comprehensive stroke center would add a median of 8.3 minutes. CONCLUSIONS: Within a large metropolitan area, the time cost of routing patients preferentially to PSCs and comprehensive stroke centers is low.

The Association of Prehospital Intravenous Fluids and Mortality in Patients with Penetrating Trauma.

BACKGROUND: The optimal approach to prehospital care of trauma patients is controversial, and thought to require balancing advanced field interventions with rapid transport to definitive care. OBJECTIVE: We sought principally to examine any association between the amount of prehospital IV fluid (IVF) administered and mortality. METHODS: We conducted a retrospective cohort analysis of trauma registry data patients who sustained penetrating trauma between January 2008 and February 2011, as identified in the Pennsylvania Trauma Systems Foundation registry with corresponding prehospital records from the Philadelphia Fire Department. Analyses were conducted with logistic regression models and instrumental variable analysis, adjusted for injury severity using scene vital signs before the intervention was delivered. RESULTS: There were 1966 patients identified. Overall mortality was 22.60%. Approximately two-thirds received fluids and one-third did not. Both cohorts had similar Trauma and Injury Severity Score-predicted mortality. Mortality was similar in those who received IVF (23.43%) and those who did not (21.30%) (p = 0.212). Patients who received IVF had longer mean scene times (10.82 min) than those who did not (9.18 min) (p < 0.0001), although call times were similar in those who received IVF (24.14 min) and those who did not (23.83 min) (p = 0.637). Adjusted analysis of 1722 patients demonstrated no benefit or harm associated with prehospital fluid (odds ratio [OR] 0.905, 95% confidence interval [CI] 0.47-1.75). Instrumental variable analysis utilizing variations in use of IVF across different Emergency Medical Services (EMS) units also found no association between the unit's percentage of patients that were provided fluids and mortality (OR 1.02, 95% CI 0.96-1.08). CONCLUSIONS: We found no significant difference in mortality or EMS call time between patients who did or did not receive prehospital IVF after penetrating trauma.

Accuracy of Emergency Medical Services Dispatcher and Crew Diagnosis of Stroke in Clinical Practice.

BACKGROUND: Accurate recognition of stroke symptoms by Emergency Medical Services (EMS) is necessary for timely care of acute stroke patients. We assessed the accuracy of stroke diagnosis by EMS in clinical practice in a major US city. METHODS AND RESULTS: Philadelphia Fire Department data were merged with data from a single comprehensive stroke center to identify patients diagnosed with stroke or TIA from 9/2009 to 10/2012. Sensitivity and positive predictive value (PPV) were calculated. Multivariable logistic regression identified variables associated with correct EMS diagnosis. There were 709 total cases, with 400 having a discharge diagnosis of stroke or TIA. EMS crew sensitivity was 57.5% and PPV was 69.1%. EMS crew identified 80.2% of strokes with National Institutes of Health Stroke Scale (NIHSS) ≥5 and symptom duration <6 h. In a multivariable model, correct EMS crew diagnosis was positively associated with NIHSS (NIHSS 5-9, OR 2.62, 95% CI 1.41-4.89; NIHSS ≥10, OR 4.56, 95% CI 2.29-9.09) and weakness (OR 2.28, 95% CI 1.35-3.85), and negatively associated with symptom duration >270 min (OR 0.41, 95% CI 0.25-0.68). EMS dispatchers identified 90 stroke cases that the EMS crew missed. EMS dispatcher or crew identified stroke with sensitivity of 80% and PPV of 50.9%, and EMS dispatcher or crew identified 90.5% of patients with NIHSS ≥5 and symptom duration <6 h. CONCLUSION: Prehospital diagnosis of stroke has limited sensitivity, resulting in a high proportion of missed stroke cases. Dispatchers identified many strokes that EMS crews did not. Incorporating EMS dispatcher impression into regional protocols may maximize the effectiveness of hospital destination selection and pre-notification.

Adult out-of-hospital cardiac arrest in philadelphia from 2008-2012: An epidemiological study.

BACKGROUND: Wide variation in out-of-hospital cardiac arrest (OHCA) survival has been reported, with low survival in urban settings. We sought to describe the epidemiology of OHCA in Philadelphia, Pennsylvania, the fifth largest U.S. city, and identify potential areas for targeted interventions to improve survival. METHODS AND RESULTS: Retrospective chart review of adult, non-traumatic, OHCA occurring in Philadelphia between 2008 and 2012. We determined incidence and epidemiological factors including: demographics, initial cardiac rhythm, bystander cardiopulmonary resuscitation, automated external defibrillator use, return of spontaneous circulation and 30-day survival. 5198 cases of adult, non-traumatic OHCA were identified. The incidence was 81.5/100,000. The majority of cases occurred in a residence (76.2%); 30.4% were witnessed events; the initial cardiac rhythm was pulseless ventricular tachycardia or ventricular fibrillation in 6.2% of cases, pulseless electrical activity in 21.0%, asystole in 38.3% and was unknown or undocumented in the remaining 34.5%. Multivariate logistic regression analysis demonstrated increased 30-day survival with younger age, shockable cardiac rhythms, and daytime arrest. 30-day survival was 8.1% for EMS-assessed patients and 8.6% for EMS-transported patients. CONCLUSIONS: Philadelphia's reported incidence is consistent with urban settings although the survival rate is higher than other urban centers.

Recognition of Stroke by EMS is Associated with Improvement in Emergency Department Quality Measures.

OBJECTIVE: Hospital arrival via Emergency Medical Services (EMS) and EMS prenotification are associated with faster evaluation and treatment of stroke. We sought to determine the impact of diagnostic accuracy by prehospital providers on emergency department quality measures. METHODS: A retrospective study was performed of patients presenting via EMS between September 2009 and December 2012 with a discharge diagnosis of transient ischemic attack (TIA), ischemic stroke (IS), or intracerebral hemorrhage (ICH). Hospital and EMS databases were used to determine EMS impression, prehospital and in-hospital time intervals, EMS prenotification, NIH stroke scale (NIHSS), symptom duration, and thrombolysis rate. RESULTS: 399 cases were identified: 14.5% TIA, 67.2% IS, and 18.3% ICH. EMS providers correctly recognized 57.6% of cases. Compared to cases missed by EMS, correctly recognized cases had longer median on-scene time (17 vs. 15 min, p = 0.01) but shorter transport times (12 vs. 15 min, p = 0.001). Cases correctly recognized by EMS were associated with shorter door-to-physician time (4 vs. 11 min, p < 0.001) and shorter door-to-CT time (23 vs. 48 min, p < 0.001). These findings were independent of age, NIHSS, symptom duration, and EMS prenotification. Patients with ischemic stroke correctly recognized by EMS were more likely to receive thrombolytic therapy, independent of age, NIHSS, symptom duration both with and without prenotification. CONCLUSION: Recognition of stroke by EMS providers was independently associated with faster door-to-physician time, faster door-to-CT time, and greater odds of receiving thrombolysis. Quality initiatives to improve EMS recognition of stroke have the potential to improve hospital-based quality of stroke care.

Employment and residential characteristics in relation to automated external defibrillator locations.

BACKGROUND: Survival from out-of-hospital cardiac arrest (OHCA) is generally poor and varies by geography. Variability in automated external defibrillator (AED) locations may be a contributing factor. To inform optimal placement of AEDs, we investigated AED access in a major US city relative to demographic and employment characteristics. METHODS AND RESULTS: This was a retrospective analysis of a Philadelphia AED registry (2,559 total AEDs). The 2010 US Census and the Local Employment Dynamics database by ZIP code was used. Automated external defibrillator access was calculated as the weighted areal percentage of each ZIP code covered by a 400-m radius around each AED. Of 47 ZIP codes, only 9% (4) were high-AED-service areas. In 26% (12) of ZIP codes, less than 35% of the area was covered by AED service areas. Higher-AED-access ZIP codes were more likely to have a moderately populated residential area (P = .032), higher median household income (P = .006), and higher paying jobs (P =. 008). CONCLUSIONS: The locations of AEDs vary across specific ZIP codes; select residential and employment characteristics explain some variation. Further work on evaluating OHCA locations, AED use and availability, and OHCA outcomes could inform AED placement policies. Optimizing the placement of AEDs through this work may help to increase survival.

Severity-adjusted mortality in trauma patients transported by police.

STUDY OBJECTIVE: Two decades ago, Philadelphia began allowing police transport of patients with penetrating trauma. We conduct a large, multiyear, citywide analysis of this policy. We examine the association between mode of out-of-hospital transport (police department versus emergency medical services [EMS]) and mortality among patients with penetrating trauma in Philadelphia. METHODS: This is a retrospective cohort study of trauma registry data. Patients who sustained any proximal penetrating trauma and presented to any Level I or II trauma center in Philadelphia between January 1, 2003, and December 31, 2007, were included. Analyses were conducted with logistic regression models and were adjusted for injury severity with the Trauma and Injury Severity Score and for case mix with a modified Charlson index. RESULTS: Four thousand one hundred twenty-two subjects were identified. Overall mortality was 27.4%. In unadjusted analyses, patients transported by police were more likely to die than patients transported by ambulance (29.8% versus 26.5%; OR 1.18; 95% confidence interval [CI] 1.00 to 1.39). In adjusted models, no significant difference was observed in overall mortality between the police department and EMS groups (odds ratio [OR] 0.78; 95% CI 0.61 to 1.01). In subgroup analysis, patients with severe injury (Injury Severity Score >15) (OR 0.73; 95% CI 0.59 to 0.90), patients with gunshot wounds (OR 0.70; 95% CI 0.53 to 0.94), and patients with stab wounds (OR 0.19; 95% CI 0.08 to 0.45) were more likely to survive if transported by police. CONCLUSION: We found no significant overall difference in adjusted mortality between patients transported by the police department compared with EMS but found increased adjusted survival among 3 key subgroups of patients transported by police. This practice may augment traditional care.

Access to care for patients with time-sensitive conditions in Pennsylvania.

STUDY OBJECTIVE: Collective knowledge and coordination of vital interventions for time-sensitive conditions (ST-segment elevation myocardial infarction [STEMI], stroke, cardiac arrest, and septic shock) could contribute to a comprehensive statewide emergency care system, but little is known about population access to the resources required. We seek to describe existing clinical management strategies for time-sensitive conditions in Pennsylvania hospitals. METHODS: All Pennsylvania emergency departments (EDs) open in 2009 were surveyed about resource availability and practice patterns for time-sensitive conditions. The frequency with which EDs provided essential clinical bundles for each condition was assessed. Penalized maximum likelihood regressions were used to evaluate associations between ED characteristics and the presence of the 4 clinical bundles of care. We used geographic information science to calculate 60-minute ambulance access to the nearest facility with these clinical bundles. RESULTS: The percentage of EDs providing each of the 4 clinical bundles in 2009 ranged from 20% to 57% (stroke 20%, STEMI 32%, cardiac arrest 34%, sepsis 57%). For STEMI and stroke, presence of a board-certified/board-eligible emergency physician was significantly associated with presence of a clinical bundle. Only 8% of hospitals provided all 4 care bundles. However, 53% of the population was able to reach this minority of hospitals within 60 minutes. CONCLUSION: Reliably matching patient needs to ED resources in time-dependent illness is a critical component of a coordinated emergency care system. Population access to critical interventions for the time-dependent diseases discussed here is limited. A population-based planning approach and improved coordination of care could improve access to interventions for patients with time-sensitive conditions.

Effect of time of day on prehospital care and outcomes after out-of-hospital cardiac arrest.

BACKGROUND: More than 300 000 out-of-hospital cardiac arrests (OHCA) occur each year in the United States. The relationship between time of day and OHCA outcomes in the prehospital setting is unknown. Any such association may have important implications for emergency medical services resource allocation. METHODS AND RESULTS: We performed a retrospective review of cardiac arrest data from a large, urban emergency medical services system. Included were OHCA occurring in adults from January 2008 to February 2012. Excluded were traumatic arrests and cases in which resuscitation measures were not performed. Day was defined as 8 am to 7:59 pm; night, as 8 pm to 7:59 am. A relative risk regression model was used to evaluate the association between time of day and prehospital return of spontaneous circulation and 30-day survival, with adjustment for clinically relevant predictors of survival. Among the 4789 included cases, 1962 (41.0%) occurred at night. Mean age was 63.8 years (SD, 17.4 years); 54.5% were male. Patients with an OHCA occurring at night did not have significantly lower rates of prehospital return of spontaneous circulation compared with patients having daytime arrests (11.6% versus 12.8%; P=0.20). However, rates of 30-day survival were significantly lower at night (8.56% versus 10.9%; P=0.02). After adjustment for demographics, presenting rhythm, field termination, duration of call, dispatch-to-scene interval, automated external defibrillator application, bystander cardiopulmonary resuscitation, and location, 30-day survival remained significantly higher after daytime OHCA, with a relative risk of 1.10 (95% confidence interval, 1.02-1.18). CONCLUSION: Rates of 30-day survival were significantly higher for OHCA occurring during the day compared with at night, even after adjustment for patient, event, and prehospital care differences.

Characteristics and outcomes of injured patients presenting by private vehicle in a state trauma system.

BACKGROUND: Previous studies have demonstrated lower mortality among patients transported to single urban trauma centers by private vehicle (PV) compared with Emergency Medical Services (EMS). We sought to describe the characteristics and outcomes of injured patients transported by PV in a state trauma system compared to patients transported by EMS. METHODS: We performed a retrospective cohort study of state trauma registry data for patients admitted to all Pennsylvania trauma centers over 5 years (1/2003 to 12/2007). Our primary exposure of interest was prehospital mode of transport and our primary outcome of interest was in-hospital mortality. Unadjusted analyses were performed as were adjusted analyses controlling for injury severity. Data are presented as percents, odds ratios (ORs), and 95% confidence intervals. RESULTS: Of the 91132 patients analyzed, 9.6% were transported to the emergency department by PV and 90.4% by EMS. Overall Injury Severity Score (ISS) was 13.3 ± 11.0 (ISS for EMS 13.7 ± 11.3, PV 9.2 ± 7.1, P < .001), and 6.6% of patients died (EMS 7.1%, PV 1.5%, P < .001). After adjusting for injury severity, patients transported by EMS were more likely to die than PV patients (OR 1.9 [95% CI 1.5-2.4]). This effect persisted in blunt, penetrating, advanced life support, and basic life support subgroups, but not in the severely injured (ISS >15, ISS >25) subgroups. CONCLUSIONS: Nearly 10% of injured patients arrive at trauma centers by private vehicle. Transport of injured patients by EMS was associated with higher mortality than PV transport. This may reflect the effects of prehospital time, prehospital interventions, or other confounders.

Willingness to pay for emergency referral transport in a developing setting: a geographically randomized study.

OBJECTIVES: The objective was to identify the correlates of willingness to pay for ambulance transports from a rural city to a regional hospital in Guatemala. METHODS: An innovative methodology that utilizes a novel randomization technique and satellite imagery was used to select a sample of homes in Santiago Atitlán, Guatemala. The respondents were surveyed at these homes about their willingness to pay for ambulance transport to a regional hospital. A price ladder was used to elicit respondents' willingness to pay for ambulance transport, depending on the level of severity of three types of emergencies: life-threatening emergencies, disability-causing emergencies, and simple emergencies. Simple and multiple linear regression modeling was used to identify the social and economic correlates of respondents' willingness to pay for ambulance transport and to predict demand for ambulance transport at a variety of price levels. Beta coefficients (ß) expressed as percentages with 95% confidence intervals (CIs) were estimated. RESULTS: The authors surveyed 134 respondents (response rate=3.3%). In the multivariable regression models, three variables correlated with willingness to pay: household income, location of residence (rural district vs. urban district), and respondents' education levels. Correlates for ambulance transport in life-threatening emergencies included greater household daily income (ß=1.32%, 95% CI=0.63% to 2.56%), rural location of residence (ß=-37.3%, 95% CI=-51.1% to -137.5%), and higher educational levels (ß=4.41%, 95% CI=1.00% to 6.36%). Correlates of willingness to pay in disability-causing emergencies included greater household daily income (ß=1.59%, 95% CI=0.81% to 3.19%) and rural location of residence (ß=-19.4%, 95% CI=-35.7% to -89.4%). Correlates of willingness to pay in simple emergencies included rural location of residence (ß=59.4%, 95% CI=37.9% to 133.7%) and higher educational levels (ß=7.96%, 95% CI=1.96% to 11.8%). At all price levels, more individuals were willing to pay for transport for a life-threatening emergency than a disability-causing emergency. Respondents' willingness to pay was more responsive to price changes for transport during disability-causing emergencies than for transport during life-threatening emergencies. CONCLUSIONS: The primary correlates of willingness to pay for ambulance transport in Santiago Atitlán, Guatemala, are household income, location of residence (rural district vs. urban district), and respondents' education levels. Furthermore, severity of emergency significantly appears to influence how much individuals are willing to pay for ambulance transport. Willingness-to-pay information may help public health planners in resource-poor settings develop price scales for health services and achieve economically efficient allocations of subsidies for referral ambulance transport.

Dignitary medicine: adapting prehospital, preventive, tactical and travel medicine to new populations.

Dignitary Protection Medicine (DPM) is a new area of medical expertise that incorporates elements of virtually all medical and surgical specialties, drawing heavily from travel, tactical and expedition medicine. The fundamentals of DPM stem from the experiences of White House, State Department and other physicians who have traveled extensively with dignitaries. Furthermore, increased international travel of business executives and political dignitaries has mandated a need for proficiency in this realm. We sought to define the requisite knowledge base and skill sets that form the foundation of this new area of specialization.

Arriving by emergency medical services improves time to treatment endpoints for patients with severe sepsis or septic shock.

OBJECTIVES: The objective was to evaluate the effect of arrival to the emergency department (ED) by emergency medical services (EMS) on time to initiation of antibiotics, time to initiation of intravenous fluids (IVF), and in-hospital mortality in patients with severe sepsis and septic shock. METHODS: The authors performed an evaluation of prospectively collected registry data of patients with a diagnosis of severe sepsis or septic shock who presented to an urban academic ED during a 2-year period from January 1, 2005, to December 31, 2006. Descriptive and multivariate analytic methods were used to analyze the data. Using unadjusted and adjusted models, out-of-hospital patients who presented to the ED by ambulance (EMS) were compared to control patients who arrived by alternative means (non-EMS). Primary outcomes measured were ED time to initiation of antibiotics, ED time to initiation of IVF, and in-hospital mortality. RESULTS: A total of 963 severe sepsis patients were enrolled in the registry. Median time to antibiotics was 116 minutes for EMS (interquartile range [IQR] = 66 to 199) vs. 152 minutes for non-EMS (IQR = 92 to 252, p ≤ 0.001). Median time to initiation of IVF was 34 minutes for EMS (IQR = 10 to 88) and 68 minutes for non-EMS (IQR = 25 to 121, p ≤ 0.001). After adjustment for the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, age, and initial serum lactate level, no significant differences in hospital mortality were seen (adjusted relative risk [aRR] for EMS vs. non EMS = 1.24, 95% confidence interval [CI] = 0.92 to 1.66, p = 0.16). The Cox proportional hazard ratio (HR) comparing EMS to non-EMS care after similar adjustment was HR = 1.27 for IVF (95% CI = 1.10 to 1.47, p = 0.004) and HR = 1.25 for antibiotics (95% CI = 1.08 to 1.44, p = 0.003). CONCLUSIONS: Out-of-hospital care was associated with improved in-hospital processes for the care of critically ill patients. Despite shortened ED treatment times for septic patients who arrive by EMS, a mortality benefit could not be demonstrated.

A 52-year-old man with malaise and a petechial rash.

BACKGROUND: Capnocytophaga canimorsus is a Gram-negative, fusiform, rod-shaped organism that is part of the normal oral flora of dogs, cats, and other animals. A significant number of Emergency Department (ED) patients are surgically or functionally asplenic and may be at marked risk for overwhelming post-splenectomy infection (OPSI). OPSI has a mortality rate estimated to be up to 70%. The risk of sepsis is estimated to be 30-60 times greater after splenectomy, and C. canimorsus is one of the organisms that can cause catastrophic OPSI. OBJECTIVES: To describe a case of C. canimorsus septic shock in a post-splenectomy patient and review the epidemiology of OPSI, the role of the spleen in protecting the body from infection, and the potential role of early goal-directed therapy in the resuscitation of patients with OPSI. CASE REPORT: A 52 year-old man with a past medical history significant for idiopathic thrombocytopenic purpura (status post-splenectomy), and non-Hodgkin lymphoma (treated for cure), was brought to the ED with the chief complaints of light-headedness, malaise, and a rapidly spreading rash. He was found to be hypotensive, tachycardic, and tachypneic, and had a marked lactic acidosis. He was aggressively resuscitated with large volume fluid resuscitation and treated empirically with broad-spectrum antibiotics for septic shock of unclear etiology. His clinical course was complicated by acute lung injury and renal failure. Blood cultures grew C. canimorsus; he was extubated on hospital day 7 and discharged home several days later in good condition. CONCLUSIONS: Patients status-post-splenectomy are at greatly increased risk for infection from encapsulated organisms and other organisms, including C. canimorsus, which is part of the normal oral flora of dogs, cats, and other animals. It can be spread to humans by bites, scratches, or less invasive forms of animal-human contact. C. canimorsus infection can lead to OPSI. Early recognition and aggressive clinical management, including early goal-directed therapy and rapid administration of antibiotics, may minimize the morbidity and mortality of this condition and other etiologies of severe sepsis and septic shock.

Injury-adjusted mortality of patients transported by police following penetrating trauma.

BACKGROUND: More than a decade ago, the city of Philadelphia began allowing police transport of penetrating trauma patients. OBJECTIVES: The objective was to determine the relation between prehospital mode of transport (police department [PD] vs. Philadelphia Fire Department (PFD) emergency medical services [EMS]) and survival in subjects with proximal penetrating trauma. METHODS: The authors performed a retrospective cohort study of prospectively collected trauma registry data. All subjects who sustained proximal penetrating trauma and who presented to a Level I urban trauma center over a 5-year period (January 1, 2003, to December 31, 2007) were included. Mortality for subjects presenting by EMS was compared to that of those who arrived by PD transport in unadjusted and adjusted analyses. Unadjusted analyses were performed using the chi-square test, Wilcoxon rank sum test, and Student's t-test. Adjusted analyses were performed using logistic regression using the Trauma Injury Severity Score (TRISS) methodology. Data are presented as percentages, odds ratios (ORs), and 95% confidence intervals (CIs). Total hospital length of stay was examined as a secondary outcome. RESULTS: Of the 2,127 subjects, 26.8% were transported to the emergency department (ED) by PD, and 73.2% by EMS. The mean(±standard deviation [SD]) age of PD subjects was 26.3 (±9.1) years and 92% were male versus EMS subjects whose mean (±SD) age was 31.5 (±11.8) years and of whom 87% were male. Overall, 70.8% sustained a gunshot wound (GSW), and 29.2% sustained a stab wound (SW). Overall Injury Severity Score (ISS) was 11.21 (ISS for PD, 14.2±17.5; for EMS, 10.1±14.5; p<0.001), and 16.6% of the subjects died (PD, 21.4±0.41%; EMS, 14.8±0.36%; p<0.001). In unadjusted analyses, PD subjects were more likely to die than EMS subjects (OR=1.6, 95% CI=1.2 to 2.0; p<0.001). When adjusting for injury severity using TRISS, there was no difference in survival between PD and EMS subjects (OR=1.01, 95% CI=0.63 to 1.61). Median length of hospital stay was 1 day and did not differ according to mode of prehospital transport (p=0.159). CONCLUSIONS: Although unadjusted mortality appears to be higher in PD subjects, these findings are explained by the more severely injured population transported by PD. The current practice of permitting police officers to transport penetrating trauma patients should be continued.

Prehospital care and new models of regionalization.

This article summarizes the discussions of the emergency medical services (EMS) breakout session at the June 2010 Academic Emergency Medicine consensus conference "Beyond Regionalization: Integrated Networks of Emergency Care." The group focused on prehospital issues such as the identification of patients by EMS personnel, protocol-driven destination selection, bypassing closer nondesignated centers to transport patients directly to more distant designated specialty centers, and the modes of transport to be used as they relate to the regionalization of emergency care. It is our hope that the proposed research agenda will be advanced in a way that begins to rigorously approach the unanswered research questions and that these answers, in turn, will lead to an evidence-based, cohesive, comprehensive, and more uniform set of guidelines that govern the delivery and practice of prehospital emergency care.

Out-of-hospital characteristics and care of patients with severe sepsis: a cohort study.

PURPOSE: Early recognition and treatment in severe sepsis improve outcomes. However, out-of-hospital patient characteristics and emergency medical services (EMS) care in severe sepsis is understudied. Our goals were to describe out-of-hospital characteristics and EMS care in patients with severe sepsis and to evaluate associations between out-of-hospital characteristics and severity of organ dysfunction in the emergency department (ED). MATERIALS AND METHODS: We performed a secondary data analysis of existing data from patients with severe sepsis transported by EMS to an academic medical center. We constructed multivariable linear regression models to determine if out-of-hospital factors are associated with serum lactate and sequential organ failure assessment (SOFA) in the ED. RESULTS: Two hundred sixteen patients with severe sepsis arrived by EMS. Median serum lactate in the ED was 3.0 mmol/L (interquartile range, 2.0-5.0) and median SOFA score was 4 (interquartile range, 2-6). Sixty-three percent (135) of patients were transported by advanced life support providers and 30% (62) received intravenous fluid. Lower out-of-hospital Glasgow Coma Scale score was independently associated with elevated serum lactate (P < .01). Out-of-hospital hypotension, greater respiratory rate, and lower Glasgow Coma Scale score were associated with greater SOFA (P < .01). CONCLUSIONS: Out-of-hospital fluid resuscitation occurred in less than one third of patients with severe sepsis, and routinely measured out-of-hospital variables were associated with greater serum lactate and SOFA in the ED.

Out-of-hospital fluid in severe sepsis: effect on early resuscitation in the emergency department.

BACKGROUND: Early identification and treatment of patients with severe sepsis improves outcome, yet the role of out-of-hospital intravenous (IV) fluid is unknown. OBJECTIVE: To determine if the delivery of out-of-hospital fluid in patients with severe sepsis is associated with reduced time to achievement of goal-oriented resuscitation in the emergency department (ED). METHODS: We performed a secondary data analysis of a retrospective cohort study in a metropolitan, tertiary care, university-based medical center supported by a two-tiered system of out-of-hospital emergency medical services (EMS) providers. We studied the association between delivery of out-of-hospital fluid by advanced life support (ALS) providers and the achievement of resuscitation endpoints (central venous pressure [CVP] > or =8 mmHg, mean arterial pressure [MAP] > or =65 mmHg, and central venous oxygen saturation [ScvO(2)] > or =70%) within six hours after triage during early goal-directed therapy (EGDT) in the ED. RESULTS: Twenty five (48%) of 52 patients transported by ALS with severe sepsis received out-of-hospital fluid. Data for age, gender, source of sepsis, and presence of comorbidities were similar between patients who did and did not receive out-of-hospital fluid. Patients receiving out-of-hospital fluid had lower out-of-hospital mean (+/- standard deviation) systolic blood pressure (95 +/- 40 mmHg vs. 117 +/- 29 mmHg; p = 0.03) and higher median (interquartile range) Sequential Organ Failure Assessment (SOFA) scores in the ED (7 [5-8] vs. 4 [4-6]; p = 0.01) than patients not receiving out-of-hospital fluid. Despite greater severity of illness, patients receiving out-of-hospital fluid approached but did not attain a statistically significant increase in the likelihood of achieving MAP > or =65 mmHg within six hours after ED triage (70% vs. 44%, p = 0.09). On average, patients receiving out-of-hospital fluid received twice the fluid volume within one hour after ED triage (1.1 L [1.0-2.0 L] vs. 0.6 L [0.3-1.0 L]; p = 0.01). No difference in achievement of goal CVP (72% vs. 60%; p = 0.6) or goal ScvO(2) (54% vs. 36%; p = 0.25) was observed between groups. CONCLUSIONS: Less than half of patients with severe sepsis transported by ALS received out-of-hospital fluid. Patients receiving out-of-hospital IV access and fluids approached but did not attain a statistically significant increase in the likelihood of achieving goal MAP during EGDT. These preliminary findings require additional investigation to evaluate the optimal role of out-of-hospital resuscitation in treating patients with severe sepsis.
