Comparison of children receiving emergent sepsis care by mode of arrival

ObjectiveTo determine if differences in patient characteristics, treatments, and outcomes exist between children with sepsis who arrive by emergency medical services (EMS) versus their own mode of transport (self-transport).MethodsRetrospective cohort study of patients who presented to the Emergency Department (ED) of two large children's hospitals and treated for sepsis from November 2013 to June 2017. Presentation, ED treatment, and outcomes, primarily time to first bolus and first parental antibiotic, were compared between those transported via EMS versus patients who were self-transported.ResultsOf the 1813 children treated in the ED for sepsis, 1452 were self-transported and 361 were transported via EMS. The EMS group were more frequently male, of black race, and publicly insured than the self-transport group. The EMS group was more likely to have a critical triage category, receive initial care in the resuscitation suite (51.9 vs. 22%), have hypotension at ED presentation (14.4 vs. 5.4%), lactate >2.0 mmol/L (60.6 vs. 40.8%), vasoactive agents initiated in the ED (8.9 vs. 4.9%), and to be intubated in the ED (14.4 vs. 2.8%). The median time to first IV fluid bolus was faster in the EMS group (36 vs. 57 min). Using Cox LASSO to adjust for potential covariates, time to fluids remained faster for the EMS group (HR 1.26, 95% CI 1.12, 1.42). Time to antibiotics, ICU LOS, 3- or 30-day mortality rates did not differ, yet median hospital LOS was significantly longer in those transported by EMS versus self-transported (6.5 vs. 5.3 days).ConclusionsChildren with sepsis transported by EMS are a sicker population of children than those self-transported on arrival and had longer hospital stays. EMS transport was associated with earlier in-hospital fluid resuscitation but no difference in time to first antibiotic. Improved prehospital recognition and care is needed to promote adherence to both prehospital and hospital-based sepsis resuscitation benchmarks.     

Characterization of Children with Septic Shock Cared for by Emergency Medical Services

Objective: To inform the future development of a pediatric prehospital sepsis tool, we sought to 1) describe the characteristics, emergent care, and outcomes for children with septic shock who are transported by emergency medicine services (EMS) and compare them to those self-transported; and 2) determine the EMS capture rate of common sepsis screening parameters and the concordance between the parameters documented in the EMS record and in the emergency department (ED) record. Methods: This is a retrospective cohort study of children ages 0 through 21 years who presented to a pediatric ED with septic shock between 11/2013 and 06/2016. Data, collected by electronic and manual chart review of EMS and ED records, included demographics, initial vital signs in both EMS and ED records, ED triage level, site of initial ED care, ED disposition, ED therapeutic interventions, outcomes, and times associated with processes. Potential screening parameters were dichotomized as normal vs. abnormal based on age-dependent normative data. Results: Of the children with septic shock treated in our ED, 19.3% arrived via EMS. These children as compared to those self-transported were more likely (i.e., p?<?0.05) to be male, have public insurance, receive initial care in the ED resuscitation suite, be hypotensive on arrival, receive their first ED fluid bolus sooner (33 vs. 58?minutes), receive vasoactive agents, be mechanically ventilated in the first 24?hours, and have slightly longer length of hospital stays. Both groups had similar times to antibiotics. While poor outcomes were rare, the 3- and 30-day mortalities were similar for both groups. EMS capture rates were highest for heart rate and respiratory rate and lowest for temperature, glucose, and blood pressure. Interrater reliability was highest for heart rate. Conclusions: Children presenting to the ED with septic shock transported by EMS represent a critically ill subset of modest proportions. Realization of a sepsis screening tool for this vulnerable population will require both creation of a tool containing a limited subset of objective parameters along with processes to ensure capture.     

The Epidemiology of Emergency Medical Services Use by Children: An Analysis of the National Hospital Ambulatory Medical Care Survey

Objective. There is an absence of nationally representative data describing pediatric patients who use emergency medical services (EMS) andthe factors associated with EMS use by children. This study characterizes pediatric emergency department (ED) visits for which the patient arrived by EMS andidentifies factors associated with those visits using a nationally representative database. Methods. A secondary analysis of the ED component of the 1997–2000 National Hospital Ambulatory Medical Care Survey was performed. The dependent variable was the mode of arrival to the ED (EMS vs. not EMS), andindependent variables were grouped into four domains: demographic, clinical, system, andservice characteristics. Bivariate analyses andmultivariate logistic regression analyses were conducted. Results. There were 110.9 million ED visits by children aged <19 years between 1997 and2000. Pediatric patients constituted 27.3% of all ED visits during this time, and7.9 million (7.1%) of these patients arrived via EMS. Pediatric patients represented 13% of all EMS transports. The annual EMS utilization rate by children was 26 per 1,000, compared with 66 per 1,000 in the adult population (p < 0.001). Sixteen percent of children transported by EMS were admitted to the hospital. Sixty-two percent of pediatric patients arriving at the ED by EMS were transported as a result of injury or poisoning. Characteristics significantly associated with arrival by EMS in the final multivariate model included demographic (age, African American race, urban residence), clinical (need for greater immediacy of care, illnesses associated with certain diagnoses), andservice (greater number of diagnostic services) variables. Conclusions. Pediatric patients transported by EMS are more likely to have injuries andpoisoning, andhave higher-acuity illness than those arriving at the ED by other means. The epidemiology of pediatric EMS use may have important operational, training, andpublic health implications andrequires further study.     

Patients Immobilized with a Long Spine Board Rarely Have Unstable Thoracolumbar Injuries

Most Emergency Medical Services (EMS) protocols require spine immobilization with both a cervical collar and long spine board for patients with suspected spine injuries. The goal of this research was to determine the prevalence of unstable thoracolumbar spine injuries among patients receiving prehospital spine immobilization: a 4-year retrospective review of adult subjects who received prehospital spine immobilization and were transported to a trauma center. Prehospital and hospital records were linked. Data was reviewed to determine if spine imaging was ordered, whether acute thoracolumbar fractures, dislocations, or subluxations were present. Thoracolumbar injuries were classified as unstable if operative repair was performed. Prehospital spine immobilization was documented on 5,593 unique adult subjects transported to the study hospital. A total of 5,423 (97.0%) prehospital records were successfully linked to hospital records. The subjects were 60.2% male, with a mean age of 40.6 (SD = 17.5) years old. An total of 5,286 (97.4%) subjects had sustained blunt trauma. Hospital providers ordered imaging to rule out spine injury in 2,782 (51.3%) cases. An acute thoracolumbar fracture, dislocation, or subluxation was present in 233 (4.3%) cases. An unstable injury was present in 29 (0.5%) cases. No unstable injuries were found among the 951 subjects who were immobilized following ground level falls. Hospital providers ordered at least one spine x-ray or CT in most patients, and a thoracolumbar imaging in half of all patients immobilized. Only 0.5% of patients who received prehospital spine immobilization had an unstable thoracolumbar spine injury.     

Hypoglycemia Emergencies: Factors Associated with Prehospital Care,Transportation Status,Emergency Department Disposition,and Cost

Objectives: The objectives of this study were to evaluate demographic/clinical characteristics and treatment/transportation decisions by emergency medical services (EMS) for patients with hypoglycemia and link EMS activations to patient disposition, outcomes, and costs to the emergency medical system. This evaluation was to identify potential areas where improvements in prehospital healthcare could be made. Methods: This was a retrospective analysis of the National Emergency Medical Services Information System (NEMSIS) registry and three national surveys: Nationwide Emergency Department Sample (NEDS), National Hospital Ambulatory Medical Care Survey (NHAMCS), and Medical Expenditure Panel Survey (MEPS) from 2013, to examine care of hypoglycemia from the prehospital and the emergency department (ED) perspectives. Results: The study estimated 270,945 hypoglycemia EMS incidents from the NEMSIS registry. Treatments were consistent with national guidelines (i.e., oral glucose, intravenous [IV] dextrose, or glucagon), and patients were more likely to be transported to the ED if the incident was in a rural setting or they had other chief concerns related to the pulmonary or cardiovascular system. Use of IV dextrose decreased the likelihood of transportation. Approximately 43% of patients were not transported from the scene. Data from the NEDS survey estimated 258,831 ED admissions for hypoglycemia, and 41% arrived by ambulance. The median ambulance expenditure was $664?±?98. From the ED, 74% were released. The average ED charge that did not lead to hospital admission was $3106?±?86. Increased odds of overnight admission included infection and acute renal failure. Conclusions: EMS activations for hypoglycemia are sizeable and yet a considerable proportion of patients are not transported to or are discharged from the ED. Seemingly, these events resolved and were not medically complex. It is possible that implementation and appropriate use of EMS treat-and-release protocols along with utilizing programs to educate patients on hypoglycemia risk factors and emergency preparedness could partially reduce the burden of hypoglycemia to the healthcare system.     

F EW E MERGENCY M EDICAL S ERVICES P ATIENTS WITH L OWER-EXTREMITY F RACTURES R ECEIVE P REHOSPITAL A NALGESIA

Previous literature has identified prehospital pain management as an important emergency medical services (EMS) function, and few patients transported by EMS with musculoskeletal injuries receive prehospital analgesia (PA). Objectives. 1) To describe the frequency with which EMS patients with lower-extremity and hip fracture receive prehospital and emergency department (ED) analgesia; 2) to describe EMS and patient factors that may affect administration of PA to these patients; and 3) to describe the time interval between EMS and ED medication administrations. Methods. This was a four-month (April to July 2000) retrospective study of patients with a final hospital diagnosis of hip or lower-extremity fracture who were transported by EMS to a single suburban community hospital. Data including patient demographics, fracture type, EMS response, and treatment characteristics were abstracted from review of EMS and ED records. Patients who had ankle fractures, had multiple traumatic injuries, were under the age of 18 years, or did not have fractures were excluded. Results. One hundred twenty-four patients met inclusion criteria. A basic life support (BLS)-only response was provided to 20 (16.0%). Another 38 (38.4%) received an advanced life support (ALS) response and were triaged to BLS transport. Of all the patients, 22 (18.3%) received PA. Patients who received PA were younger (64.0 vs. 77.3 years, p < 0.001) and more likely to have a lower-extremity fracture other than a hip fracture (31.8% vs. 10.7%, p < 0.004). Of all patients, 113 (91.1%) received ED analgesia. Patients received analgesia from EMS almost 2.0 hours sooner that in the ED (mean 28.4 ± 36 min vs. 146 ± 74 min after EMS scene arrival, p < 0.001). Conclusion. A minority of the study group received PA. Older patients and patients with hip fracture are less likely to receive PA. It is unclear whether current EMS system design may adversely impact administration of PA. Further work is needed to clarify whether patient need or EMS practice patterns result in low rates of PA.     

Potential time savings by prehospital administration of activated charcoal

Objective. Activated charcoal (AC) has been proven useful in many toxic ingestions. Theoretically, administration of AC in the prehospital environment could save valuable time in the treatment of patients who have sustained potentially toxic oral ingestions. The purpose of this study was to determine the frequency of prehospital AC administration and to identify time savings that could potentially result from field AC administration.

Methods. Adult patients with a chief complaint of toxic ingestion who had complete emergency medical services (EMS) and emergency department (ED) records and no medical treatment (gastric emptying, AC administration) prior to EMS arrival were eligible for inclusion. Data obtained from EMS and ED records included time of EMS departure from the scene, time of EMS arrival at the ED, and time of administration of AC in the ED. Since most EMS agencies in this system do not insert gastric tubes, patients requiring gastric tube placement for administration of AC were excluded.

Results. Twenty-nine of 117 (24.8%) adult patients received oral AC with no other intervention. None of the 117 patients received AC in the prehospital setting. The EMS transport time for these patients ranged from 5 to 43 minutes (mean 16.2 ± 9.7 minutes). The delay from ED arrival to AC administration ranged from 5 to 94 minutes (mean 48.8 ± 24.1 minutes), and was more than 60 minutes for 14 (48.2%) of the patients. The total time interval from scene departure to ED AC administration ranged from 17 to 111 minutes (mean 65.0 ± 25.9 minutes). Conclusions. In a selected subset of patients who tolerate oral AC, prehospital administration of AC could result in earlier and potentially more efficacious AC therapy. Prospective study of the benefits and feasibility of prehospital AC administration is indicated.     

Accuracy of Paramedic Broselow Tape Use in the Prehospital Setting

Introduction. Previous literature has documented that prehospital 12-lead electrocardiography (ECG) decreases the time to reperfusion in patients with an acute ST-segment elevation myocardial infarction (STEMI). Objective. To compare time to ECG, time to angioplasty suite (laboratory), andtime to reperfusion in emergency medical services (EMS) STEMI patients, who received care through three different processes. Methods. The setting was a large suburban community teaching hospital with emergency department (ED)-initiated single-page acute myocardial infarction (AMI) team activation for STEMI patients. The population was STEMI patients transported by EMS from January 2003 to October 2005. Not all EMS agencies had prehospital 12-lead ECG capability. Paramedics interpret andverbally report clinical assessment andECG findings via radio. The AMI team is activated at the discretion of the emergency physician 1) before patient arrival to the ED based on EMS assessment, 2) after ED evaluation with EMS ECG, or 3) after ED evaluation andED ECG. Time intervals were calculated from ED arrival. To assess the impact of interventions on performance targets, we also report the proportion of patients who arrived in laboratory within 60 minutes andreperfusion within 90 minutes of arrival. Parametric andnonparametric statistics are used for analysis. Results. During the study period, there were 164 STEMI patients transported by EMS; mean age was 66.1 years, and56% were male. Of these, 93 (56.7%) had an EMS ECG and31 (33%) had AMI team activation before ED arrival. Mean time to laboratory for all patients was 49.8 ± 34.4 minutes andtime to reperfusion was 93.2 +/? 34.5 min. Patients with prearrival activation were transported to laboratory sooner (mean, 24.3 vs. 53. 4 minutes; p < 0.001) andreceived reperfusion sooner than all other patients (mean, 70.4 vs. 96.3 minutes; p = 0.007). More prearrival activation patients met performance targets to laboratory (96.7% vs. 73.7%; p = 0.009) andreperfusion (85.2% vs. 51.0%; p = 0.003). There was no difference in time to laboratory or to reperfusion for patients who received EMS ECG but no prearrival activation compared with those who received EMS transport alone. Conclusions. A minority of patients with EMS ECGs had prearrival AMI team activation. EMS ECGs combined with systems that activate hospital resources, but not EMS ECGs alone, decrease time to laboratory andreperfusion.     

Retrospective Evaluation of Risk Factors for Pediatric Secondary Transport

Objective: Emergency medical services (EMS) typically transports patients to the nearest emergency department (ED). After initial presentation, children who require specialized care must undergo secondary transport, exposing them to additional risks and delaying definitive treatment. EMS direct transport protocols exist for major trauma and certain adult medical conditions, however the same cannot be said for pediatric medical conditions or injuries that do not meet trauma center criteria (‘minor trauma’). To explore the utility of such future protocols, we sought to first describe the pediatric secondary transport population and examine prehospital risk factors for secondary transport. Methods: Pediatric secondary transport patients aged 0–18 years were identified. Patients meeting state EMS trauma protocol criteria or who were clinically unstable were excluded. Data were abstracted by chart review of EMS, community hospital ED, and specialty hospital records. Patients were compared to control patients with similar conditions who did not require secondary transport. Results: This study identified 211 medical or minor trauma pediatric secondary transport patients between 2013 and 2014. The three most prevalent conditions were seizure (n = 52), isolated orthopedic injury (n = 49), and asthma/respiratory distress (n = 27). Increased odds of secondary transport for seizure patients were associated with administration of supplemental oxygen, glucose measurement, and online medical direction; for isolated orthopedic injuries, online medical direction; and for asthma/respiratory distress, administration of supplemental oxygen, and online medical direction. Decreased odds of secondary transport for seizure patients were associated with a higher GCS; for isolated orthopedic injuries, increased age and oxygen saturation; and for asthma/respiratory distress, administration of albuterol only. Conclusions: Children with seizures, isolated orthopedic injuries, and asthma/respiratory distress comprised the majority of the medical or minor trauma pediatric secondary transport population. Each of those conditions had specific risk factors for secondary transport. This study's results provide information to guide future prospective studies and the development of direct transport protocols for those populations.     

Community Implementation of a Prehospital Spinal Immobilization Guideline

Objective: The purpose of this study was to qualitatively describe the underpinnings of the successful implementation of a collaborative prehospital spinal immobilization guideline throughout the emergency medical services (EMS) community in two counties in Colorado. We also describe lessons learned that may be beneficial to other communities considering similar initiatives. Methods: Qualitative data were collected from key informants who were directly involved in the implementation of a new prehospital spinal immobilization guideline among four community hospitals in two different hospital systems and the associated EMS providers within the two counties. We interviewed a purposively selected sample of emergency department (ED) physicians and other ED staff, hospital decision makers, EMS educators as well as fire department and EMS medical directors. Data were collected and reviewed until saturation was achieved. We conducted qualitative analysis to summarize and synthesize themes. Results: Ten key informants were interviewed, at which point saturation was achieved and several clear themes emerged. Participants described successful community-wide guideline implementation despite a history of competition, isolation, and conflict between the various EMS organizations and hospitals on past EMS and trauma initiatives. Factors related to success included the nearly universal perception that the initiative was “cutting edge” and thus an important paradigm shift in care for the community, as a whole. Participants reported the ability of community stakeholders to jointly assure a collaborative approach, characterized by intensive education for EMS personnel and others involved, and the ability of the community to together secure the new equipment required for success. Conclusions: Key informants described a convergence of factors as leading to the successful implementation of a prehospital spinal immobilization guideline. Lessons learned regarding how to overcome a tradition of competition and isolation to allow for success may be useful to other communities considering similar initiatives.     

New Immobilization Guidelines Change EMS Critical Thinking in Older Adults With Spine Trauma

Objective: The impact of immobilization techniques on older adult trauma patients with spinal injury has rarely been studied. Our advisory group implemented a change in the immobilization protocol used by emergency medical services (EMS) professionals across a region encompassing 9 trauma centers and 24 EMS agencies in a Rocky Mountain state using a decentralized process on July 1, 2014. We sought to determine whether implementing the protocol would alter immobilization methods and affect patient outcomes among adults ≥60 years with a cervical spine injury. Methods: This was a 4-year retrospective study of patients ≥60 years with a cervical spine injury (fracture or cord). Immobilization techniques used by EMS professionals, patient demographics, injury characteristics, and in-hospital outcomes were compared before (1/1/12–6/30/14) and after (7/1/14–12/31/15) implementation of the Spinal Precautions Protocol using bivariate and multivariate analyses. Results: Of 15,063 adult trauma patients admitted to nine trauma centers, 7,737 (51%) were ≥60 years. Of those, 237 patients had cervical spine injury and were included in the study; 123 (51.9%) and 114 (48.1%) were transported before and after protocol implementation, respectively. There was a significant shift in the immobilization methods used after protocol implementation, with less full immobilization (59.4% to 28.1%, p < 0.001) and an increase in the use of both a cervical collar only (8.9% to 27.2%, p < 0.001) and not using any immobilization device (15.5% to 31.6%, p = 0.003) after protocol implementation. While the proportion of patients who only received a cervical collar increased after implementing the Spinal Precautions Protocol, the overall proportion of patients who received a cervical collar alone or in combination with other immobilization techniques decreased (72.4% to 56.1%, p = 0.01). The presence of a neurological deficit (6.5% vs. 5.3, p = 0.69) was similar before and after protocol implementation; in-hospital mortality (adjusted odds ratio = 0.56, 95% confidence interval: 0.24–1.30, p = 0.18) was similar post–protocol implementation after adjusting for injury severity. Conclusions: There were no differences in neurologic deficit or patient disposition in the older adult patient with cervical spine trauma despite changes in spinal restriction protocols and resulting differences in immobilization devices.     

Prehospital Glucose Testing for Children with Seizures: A Proposed Change in Management

Objective: Many Emergency Medicine Services (EMS) protocols require point-of-care blood glucose testing (BGT) for any pediatric patient who presents with seizure or altered level of conscious. Few data describe the diagnostic yield of BGT when performed on all pediatric seizures regardless of presenting mental status. We analyzed a large single center dataset of pediatric patients presenting with prehospital seizures to determine the prevalence of hypoglycemic seizures and the utility of repeat BGT in the emergency department (ED). Methods: This was a retrospective, IRB-approved chart analysis of all pediatric patients (≤14 years) transported by EMS to the Harbor-UCLA pediatric ED over a 2-year period with a chief complaint of seizure. Cases were selected in which witnessed seizures had occurred in the field by family or EMS. Chart review included prehospital, nursing and physician records. Hypoglycemia was defined as blood glucose <60 mg/dL. Analysis included blood glucose, witnessed field seizure, initial mental status assessed by Glasgow Coma Scale (GCS), and further mental status assessments, along with age, sex, and medical history. Medical records were reviewed for subsequent BGT and patient outcome. Results: A total 770 children were transported by EMS due to seizures. Four patients (0.5%) had recorded hypoglycemia in the field, yet only two received treatment to raise blood glucose. Additionally, one child (0.1%) was normoglycemic (81 mg/dL) in the field with hypoglycemia (43 mg/dL) in the ED but required no intervention. Two were found by EMS to have an ALOC (GCS ≤ 12) and hypoglycemia. Only the patient with hypoglycemia secondary to a suspected glipizide ingestion received ED glucose administration. The most common discharge diagnosis was simple febrile seizure (38.6%). Conclusion: Hypoglycemia in the pediatric seizure patient is extremely rare, thus universal field BGT has low utility and potential downstream effects. We propose a novel algorithm for the initial evaluation and management of prehospital pediatric seizures. Although limited to a retrospective analysis of a single medical center, our findings suggest the importance of reassessing prehospital seizure protocols. A larger patient sample should be studied to validate these findings and identify unique cases where glucose testing might be useful.     

Diagnostic accuracy of prehospital electrocardiograms interpreted remotely by emergency physicians in myocardial infarction patients

BackgroundPrehospital 12‑lead electrocardiogram (ECG) is the most widely used screening tool for recognition of ST-segment elevation myocardial infarction (STEMI). However, prehospital diagnosis of STEMI based solely on ECGs can be challenging.ObjectivesTo evaluate the ability of emergency department (ED) physicians to accurately interpret prehospital 12‑lead ECGs from a remote location.MethodsAll suspected prehospital STEMI patients who were transported by EMS and underwent angiography between 2006 and 2014 were included. We reviewed prehospital ECGs and grouped them based on: 1) presence or absence of a culprit artery lesion following angiography; and 2) whether they met the 3rd Universal Definition of Myocardial Infarction. We also described characteristics of ECGs that were misinterpreted by ED physicians.ResultsA total of 625 suspected STEMI cases were reviewed. Following angiography, 94% (590/625) of patients were found having a culprit artery lesion, while 6% (35/625) did not. Among these 35 patients, 24 had ECGs that mimicked STEMI criteria and 9 had non-ischemic signs. Upon ECG reinterpretation, 92% (577/625) had standard STEMI criteria while 8% (48/625) did not. Among these 48 patients, 35 had ischemic signs ECGs and 13 did not. Characteristics of misinterpreted ECGs included pericarditis, early repolarization, STE > 1 mm (1‑lead only), and negative T-wave.ConclusionsRemote interpretation of prehospital 12‑lead ECGs by ED physicians was a useful diagnostic tool in this EMS system. Even if the rate of ECG misinterpretation is low, there is still room for ED physicians operating from a remote location to improve their ability to accurately diagnose STEMI patients.     

Information Loss in Emergency Medical Services Handover of Trauma Patients

Introduction. Little is known about how effectively information is transferred from emergency medical services (EMS) personnel to clinicians in the emergency department receiving the patient. Information about prehospital events and findings can help ensure expedient and appropriate care. The trauma literature describes 16 prehospital data points that affect outcome and therefore should be included in the EMS report when applicable. Objective. To determine the degree to which information presented in the EMS trauma patient handover is degraded. Methods. At a level I trauma center, patients meeting criteria for the highest level of trauma team activation (“full trauma”) were enrolled. As part of routine performance improvement, the physician leadership of the trauma program watched all available video-recorded full trauma responses, checking off whether the data points appropriate to the case were verbally “transmitted” by the EMS provider. Two EMS physicians then each independently reviewed the trauma team's chart notes for 50% of the sample (and a randomly selected 15% of the charts to assess agreement) and checked off whether the same elements were documented (“received”) by the trauma team. The focus was on data elements that were “transmitted” but not “received.” Results. In 96 patient handovers, a total of 473 elements were transmitted, of which 329 were received (69.6%). On the average chart, 72.9% of the transmitted items were received (95% confidence interval 69.0%–76.8%). The most commonly transmitted data elements were mechanism of injury (94 times), anatomic location of injury (81), and age (67). Prehospital hypotension was received in only 10 of the 28 times it was transmitted; prehospital Glasgow Coma Scale [GCS] score 10 of 22 times; and pulse rate 13 of 49 times. Conclusions. Even in the controlled setting of a single-patient handover with direct verbal contact between EMS providers and in-hospital clinicians, only 72.9% of the key prehospital data points that were transmitted by the EMS personnel were documented by the receiving hospital staff. Elements such as prehospital hypotension, GCS score, and other prehospital vital signs were often not recorded. Methods of “transmitting” and “receiving” data in trauma as well as all other patients need further scrutiny.     

Potential Adverse Effects of Spinal Immobilization in Children

Abstract

Objective. The purpose of our study was to describe potential adverse effects associated with spinal immobilization following trauma among children. Methods. We conducted a prospective cohort study of children presenting to the emergency department (ED) for evaluation following trauma over a 13-month period. Children were eligible if they underwent spinal immobilization prior to physician evaluation or if they met the American College of Surgeons (ACS) guidelines for spinal immobilization but were not immobilized. We compared children who were immobilized with those who were not immobilized for self-reported pain, use of radiography to evaluate the cervical spine, ED length of stay, and ED disposition. We also report the characteristics of the cohort. Results. One hundred seventy-three spine-immobilized children and 112 children who met ACS criteria but were not immobilized were enrolled. There were differences between the two study groups, which included age, mechanism of injury, and proportion transported by emergency medical services. However, the comparison groups had comparable Pediatric Trauma Scores (PTSs) and Glasgow Coma Scale scores (GCSs). Immobilized children had a higher median pain score (3 versus 2) and were more likely to undergo cervical radiography (56.6% versus 13.4%) and be admitted to the hospital (41.6% versus 14.3%). The comparison groups had similar lengths of stay in the ED. Conclusion. Despite presenting with comparable PTSs and GCSs, children who underwent spinal immobilization following trauma had a higher degree of self-reported pain, and were much more likely to undergo radiographic cervical spine clearance and be admitted to the hospital than those who were not immobilized. Future studies are warranted to determine whether these differences are related to spinal immobilization or differences in the mechanisms of injury, injury patterns, or other variables.     

Can ems providers adequately assess trauma patients for cervical spinal injury?

Objective. To determine whether EMS providers can accurately apply the clinical criteria for clearing cervical spines in trauma patients. Methods. EMS providers completed a data form based on their initial assessments of all adult trauma patients for whom the mechanism of injury indicated immobilization. Data collected included the presence or absence of neck pain/tenderness; altered mental status; history of loss of consciousness; drug/alcohol use; neurologic deficit; and other painful/distracting injury. After transport to the ED, emergency physicians (EPs) completed an identical data form based on their assessments. Immobilization was considered to be indicated if any one of the six criteria was present. The El's and EMS providers were blinded to each other's assessments. Agreement between the EP and EMS assessments was analyzed using the kappa statistic. Results. Five-hundred seventy-three patients were included in the study. The El' and EMS assessments matched in 78.7% (n = 451) of the cases. There were 44 (7.7%) patients for whom EP assessment indicated immobilization, but the EMS assessment did not. The kappa for the individual components of the assessments ranged from 0.35 to 0.81, with the kappa for the decision to immobilize being 0.48. The EMS providers' assessments were generally more conservative than the EPs'. Conclusion. EMS and EP assessments to rule out cervical spinal injury have moderate to substantial agreement. However, the authors recommend that systems allowing EMS providers to decide whether to immobilize patients should follow those patients closely to ensure appropriate care and to provide immediate feedback to the EMS providers.     

Spinal Motion Restriction: An Educational and Implementation Program to Redefine Prehospital Spinal Assessment and Care

Abstract

Introduction. Prehospital spine immobilization has long been applied to victims of trauma in the United States and up to 5 million patients per year are immobilized mostly with a cervical collar and a backboard. Objective. The training of paramedics and emergency medical technicians on the principals of spine motion restriction (SMR) will decrease the use of backboards. Methods. The training for SMR emphasized the need to immobilize those patients with a significant potential for an unstable cervical spine fracture and to use alternative methods of maintaining spine precautions for those with lower risk. The training addressed the potential complications of the use of the unpadded backboard and education was provided about the mechanics of spine injuries. Emergency medical services (EMS} personnel were taught to differentiate between the critical multisystem trauma patients from the more common moderate, low kinetic energy trauma patients. A comprehensive education and outreach program that included all of the EMS providers (fire and private), hospitals, and EMS educational institutions was developed. Results. Within 4 months of the policy implementation, prehospital care practitioners reduced the use of the backboard by 58%. This was accomplished by a decrease in the number of patients considered for SMR with low kinetic energy and the use of other methods, such as the cervical collar only. Conclusion. The implementation of a SMR training program significantly decreases the use of backboards and allows alternative methods of maintaining spine precautions.     

Patient Characteristics and Temporal Trends in Police Transport of Blunt Trauma Patients: A Multicenter Retrospective Cohort Study

Background: Police transport (PT) of penetrating trauma patients has the potential to decrease prehospital times for patients with life-threatening hemorrhage and is part of official policy in Philadelphia, Pennsylvania. We hypothesized that rates of PT of bluntly injured patients have increased over the past decade. Methods: We used Pennsylvania Trauma Outcomes Study registry data from 2006–15 to identify bluntly injured adult patients transported to all 8 trauma centers in Philadelphia. PT was compared to ambulance transport, excluding transfers, burn patients, and private transport. We compared demographics, mechanism, and injury outcomes between PT and ambulance transport patients and used multivariable logistic regression to identify independent predictors of PT. We also identified physiological indicators and injury patterns that might have benefitted from prehospital intervention by EMS. Results: Of 28 897 bluntly injured patients, 339 (1.2%) were transported by police and 28 558 (98.8%) by ambulance. Blunt trauma accounted for 11% of PT and penetrating trauma for 89%. PT patients were younger, more likely to be male, and more likely to be African American or Asian and were more often injured by assault or motor vehicle crash. There were no significant differences presenting physiology between PT and EMS patients. In multivariable logistic regression analysis, male sex (OR 1.89, 95%CI 1.40–2.55), African American race (OR 1.71 95%CI 1.34–2.18), and Asian race (OR 2.25, 95%CI 1.22–4.14) were independently associated with PT. Controlling for injury severity and physiology, there was no significant difference in mortality between PT and EMS. Overall, 64% of PT patients had a condition that might have benefited from prehospital intervention such as supplemental oxygen for brain injury or spine stabilization for vertebral fractures. Conclusions: PT affects a small minority of blunt trauma patients, and did not appear associated with higher mortality. However, PT patients included many who might have benefited from proven, prehospital intervention. Clinicians, EMS providers, and law enforcement should collaborate to optimize use of PT within the trauma system.
