Epidemiology of non-transported emergency medical services calls in Saudi Arabia

Objectives:To determine the epidemiology of non- transported emergency medical services (EMS) calls within the EMS system at Riyadh, Saudi Arabia, to identify factors that contributes to non-transport of patients by EMS provider, and to recommend suggestions for reduction in number of non-transported calls.Methods:Retrospective analysis of 1390 patient care reports (PCR) of non-transported cases responded to, and documented by the Saudi Red Crescent Authority (SRCA) emergency medical technicians (EMTs). All PCRs of non-transported cases from 10 EMS stations, in 3 consecutive months were examined. The SRCA EMTs management in Riyadh allocated all non-transported PCRs for 3 months (March-May 2014). Constructive data that includes patients demographics, scene characteristics, trip and timing information, length of stay, clinical and assessment data, and physician contact, or presence status were extracted from those PCRs.Results:Twenty-five percent of calls made during the study period were reported as non-transported calls. Seventy percent of non-transported calls were related to refusal by patient. Approximately 22.4% of non-transported calls were canceled by dispatch. Approximately 50% of non-transported patient were in the young age group (16-30 years). In 26% of non-transported calls, the field time was restricted to 15 minutes.Conclusion:More than half of the non-transported emergency calls were reported as refused by patient/relative, while approximately one quarter were reported as cancelled calls.

Intra-aortic Balloon Pump-Dependent Patient Transports by Critical Care Paramedics

ObjectiveTransport of intra-aortic balloon pump (IABP)-dependent patients between hospitals is increasingly common. The transports are typically time-sensitive and require personnel familiar with IABP operation and management of a potentially unstable patient. This study examined transports performed by specially trained critical care paramedics in a large air medical and land critical care transport service. MethodsThis retrospective, descriptive review prospectively collected data for IABP-dependent patient transports in Ontario, Canada in a 10-year interval beginning September 2003. Call records and patient care reports were reviewed to capture demographic, patient care, adverse events, and transport-related data. Adverse events, including resuscitation medication, procedure, and patient instability, were independently reviewed by 2 investigators. ResultsThere were 162 IABP-dependent patients transported. Seventy-one were performed by land critical care transport vehicles, 60 by helicopter, and 31 by fixed wing aircraft. The mean patient age was 63.7 ± 13.8 years; the majority (72.2%) were men. Fifty-nine patients (36.4%) were inotrope or vasopressor dependent, and 46 (28.4%) were intubated and mechanically ventilated. The most common indications for IABP insertion were acute myocardial infarction requiring prompt surgical intervention (n = 70), bridge to definitive care (n = 41), and cardiogenic shock (n = 37). The mean transport time was 92.7 ± 79.4 minutes. There were 48 adverse events in 35 patients, most commonly hypotension (systolic blood pressure < 90 mm Hg, n = 18) and tachyarrhythmia requiring therapy (n = 12). There were 3 IABP-related events and 3 cases in which the transport vehicle was inoperable resulting in a transport delay. One patient with cardiogenic shock died before departing the sending hospital. Paramedics managed all events without assistance from other health care personnel. ConclusionSpecially trained critical care flight paramedics can safely transport potentially unstable IABP-dependent patients to definitive cardiac surgical care.

Acute Alcohol Use and Injury Patterns in Young Adult Prehospital Patients

The objective was to determine if acute alcohol consumption is associated with differences in injury pattern among young adult patients with traumatic injuries presenting to emergency medical services (EMS). A cross-sectional, retrospective review of prehospital patient care reports (PCRs) was conducted evaluating injured patients who presented to a collegiate EMS agency from January 1, 2011 to December 31, 2012. Included patients were age 18–24 y and sustained an injury within the previous 24 h. PCRs were reviewed independently by two abstractors to determine if the patient was documented to have acutely consumed alcohol proximate to his/her injury. Primary and secondary sites of regional body injury were recorded. Injury severity was recorded using the Revised Trauma Score (RTS). The association between primary injury site and acute alcohol use was assessed using a chi-square test. Multiple logistic regression was used to control for sex in predicting injury type. Of 440 injured patients, 135 (30.6%) had documented alcohol use prior to injury. Acute alcohol consumption altered the overall pattern of regional injury (p < 0.001). Alcohol users were more likely to present with injury secondary to assault, fall/trip, and unknown mechanism of injury (p < 0.001, all comparisons). RTS scores were statistically lower in the alcohol group (p < 0.001), although the clinical significance of this is unclear. Controlling for sex, acute alcohol consumption predicted increased risk of head/neck injury 5.59-fold (p < 0.001). Acute alcohol use in collegiate EMS patients appears to alter injury patterns in young adults and increases risk of head/neck injury. EMS providers in similar agencies should consider these trends when assessing and treating injured college-aged patients.

Use of telephone CPR advice in Ireland: Uptake by callers and delays in the assessment process

IntroductionTelephone CPR (T-CPR) has significant variations in time from call receipt to first compression, with reported delays of up to five minutes. Ireland's National Ambulance Service (NAS) uses T-CPR based on standard AMPDS questions; we aimed to identify the time to first compression and the times needed for question blocks. Ireland has a low survival rate from out-of-hospital cardiac arrest, (6% in 2013). MethodsA retrospective review of all cardiac arrests in a two-year period was carried out in one NAS region. All cardiac arrests were identified from the national registry and audio tapes and Patient Care Reports reviewed, together with survival data. Times from call handover were noted and categorised in terms of the key question items. Results202 cardiac arrests occurred in the period (36/105/year); 30 (14.9%) patients were not in cardiac arrest at the time of the call. Records were available for 145/172 patients in cardiac arrest at the time of the call. In 63/145 (43.4%) cases, the caller was not at the patient's side. Of the remaining 82 cases, in 13/82 (15.8%) CPR was underway (two survivors), in 22/82 (26.8%) the caller would not attempt T-CPR (one survivor); in 47/82 (57.3%), T-CPR was carried out (two survivors). Median time to first compression was 05:28min (range 03:18–10:29).Repeated questioning in relation to the patient's condition caused most of the delays. ConclusionsMany callers are willing to attempt T-CPR but the questioning/instruction process causes significant delays. A focused, brief questioning process is required.

Lights and Siren Transport and the Need for Hospital Intervention in Trauma Patients

Emergent ambulance transportation is associated with increased risk of collision, injury, and death for EMS professionals, patients, and the general public. Time saved using lights and siren (L&S) is typically small, and often provides minimal clinical benefit. Our objective was to investigate the frequency of L&S transports, describe the precision of the decision to employ L&S to predict the need for a time critical hospital intervention (TCHI) within 15 minutes of hospital arrival, identify clinical predictors of a TCHI, and compare clinical outcomes in patients transported by Emergency Medical Services (EMS) with and without L&S in a trauma-specific population. EMS patient care reports and trauma registry data were retrospectively reviewed for trauma patients consecutively transported from the field by three EMS agencies to three trauma centers within urban and suburban settings over a two-year period. TCHIs were collaboratively developed by the study team. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were utilized to report the precision of the decision to employ L&S to predict the need of a TCHI. Univariate and multivariate analyses determined predictors of a TCHI and compared clinical outcomes. 2,091 patients were included in the study. Of the 19.8% of patients transported with L&S, 22.9% received a TCHI. The most common TCHI was airway or respiratory procedures (87.2% of all TCHI's). The sensitivity and specificity of L&S to predict the need for a TCHI was 87.2% (95% CI 79.4–92.8) and 84.0% (95% CI 82.2–85.5), respectively. PPV was 23.0% (95% CI 23.53–38.01); NPV was 99.2% (95% CI 98.6–99.6). L&S was predictive for the need for a TCHI (p < 0.001), as was abnormal Glasgow Coma Score (p < 0.001), abnormal systolic blood pressure and age (p < 0.05 for all). Among patients that received a TCHI, over a third that were transported with L&S (36.8%) expired, compared with two of 14 patients (14.3%) not transported L&S. EMS professionals in this study demonstrated a high ability to discern which trauma patients did not require L&S. Nevertheless, L&S transport resulted in a TCHI less than one quarter of the time, suggesting an opportunity for further reduction of L&S transports in trauma patients.

Developing Surveillance Methodology for Agricultural and Logging Injury in New Hampshire Using Electronic Administrative Data Sets.

Agriculture and logging rank among industries with the highest rates of occupational fatality and injury. Establishing a nonfatal injury surveillance system is a top priority in the National Occupational Research Agenda. Sources of data such as patient care reports (PCRs) and hospitalization data have recently transitioned to electronic databases. Using narrative and location codes from PCRs, along with International Classification of Diseases, 9th Revision, external cause of injury codes (E-codes) in hospital data, researchers are designing a surveillance system to track farm and logging injury. A total of 357 true agricultural or logging cases were identified. These data indicate that it is possible to identify agricultural and logging injury events in PCR and hospital data. Multiple data sources increase catchment; nevertheless, limitations in methods of identification of agricultural and logging injury contribute to the likely undercount of injury events.

EMS Intubation Improves with King Vision Video Laryngoscopy

Introduction. Intubation success by paramedics has historically been variable. The lack of first-pass success (FPS) has been associated with increased adverse events. Various video laryngoscope (VL) devices have been investigated to improve success among paramedics. Conflicting research exists on VL vs. direct laryngoscopy (DL) by paramedics and on the effects of the specific King Vision device on FPS and overall success (OS) in an emergency medical services (EMS) system with low intubation frequency and historically low success rates. Objectives. To evaluate the effect of an ongoing training program using the King Vision VL on FPS, OS, and success per attempt when compared with DL in one suburban EMS system with low historical intubation success rates. Methods. We performed a retrospective analysis of electronic patient care reports in a suburban EMS system. We analyzed three metrics of intubation success before DL and after implementation of ongoing training with VL in both cardiac arrest and in all other indications: success per attempt, overall success, and first-pass success. We also performed an intention to treat analysis of these rates to account for protocol violations. Results. During the study period, intubation was attempted on 514 patients. There was no difference between the DL and VL groups in age, weight, gender, or percentage receiving paralytic medications. There was improvement over DL with VL in each of the outcome measures: overall success (64.9 vs. 91.5%, p < 0.01), first-pass success (43.8% vs. 74.2%, p < 0.01), and success per attempt (44.4 vs. 71.2%, p < 0.01). A subgroup analysis by indication for intubation also showed improvement in all metrics for all indications. There were several protocol violations: 11 of 376 attempts that should have used VL (2.9%) but were done with DL. An intention to treat analysis was therefore done. Again, we saw an improvement in all metrics for all indications.Conclusion. In this suburban EMS system with historically low intubation success rates and low frequency of intubation, paramedics were able to improve all measures of intubation success using the King Vision video laryngoscope and an ongoing training program when compared with direct laryngoscopy. Key words: intubation; airway management; emergency medical services; prehospital emergency care

Injury Patterns at Isle Royale National Park: An Epidemiologic Review of Injuries and Illnesses Sustained in a Remote Environment

Isle Royale National Park is a remote island in northern Lake Superior that attracts 16,000 visitors annually. The epidemiology of injuries and illnesses sustained by Isle Royale׳s visitors has not been previously studied.The purpose of this study is to examine these data and evaluate them for injury patterns. This is a retrospective observational study examining the epidemiology of injuries and illnesses sustained during the period from 2008 to 2012. Incident reports completed by park rangers were reviewed and the data sorted according to time of year, time of day, type of medical encounter, and whether the patient was stable, unstable, or required transport. Two hundred and seventy patient care reports were obtained from the National Park Service. Sixty-four percent of encounters occurred in July and August, and most patients sought care in the afternoon. Care was provided by park rangers, the majority of whom were trained to the level of emergency medical technician. Fifty-eight percent of cases were trauma related, and 20% of all cases were evacuated. The majority of incidents were trauma related. The majority of the rangers on the island are trained to the level of emergency medical technician-B and appear to offer appropriate care to the island's many visitors, utilizing the National Park Service treatment protocols and comprehensive medical kits. In addition, access to advanced medical care is readily available by air and water evacuation.

End-User Experiences and Expectations Regarding Data Registration and Reuse Before the Implementation of a (New) Electronic Health Record: A Case Study in Two University Hospitals.

Patient data stored in Electronic Health Records (EHRs) are used during care provision but are also potentially usefully reused for other purposes. Data (re)use requires good data quality, which necessitates efforts by healthcare professionals for proper data registration. However, their commitment depends on their perception of the reuse benefits. We developed a questionnaire to investigate the perception and expectations of end-users on data registration and reuse in two university hospitals starting a joint EHR implementation. Especially personnel in direct patient care reports to spend much time (40%) on data registration and this group is not willing to spend more time with the new EHR. Additionally, approximately one third of the personnel did not yet have a clear view on future developments regarding data registration and reuse. We found only small differences between hospitals.

Inaccuracy of patient care reports for identification of critical resuscitation events during out-of-hospital cardiac arrest

ObjectiveOut-of-hospital cardiac arrest (OHCA) is a leading cause of mortality in the United States. We sought to evaluate the accuracy of the patient care report (PCR) for detection of 2 clinically important events: return of spontaneous circulation (ROSC) and rearrest (RA). MethodsWe used defibrillator recordings and PCRs for Emergency Medical Services–treated OHCA collected by the Resuscitation Outcomes Consortium's Pittsburgh site from 2006 to 2008 and 2011 to 2012. Defibrillator data included electrocardiogram rhythm tracing, chest compression measurement, and audio voice recording. Sensitivity analysis was performed by comparing the accuracy of the PCR to detect the presence and number of ROSC and RA events to integrated defibrillator data. ResultsIn the 158 OHCA cases, there were 163 ROSC events and 53 RA events. The sensitivity of PCRs to identify all ROSC events was 85% (confidence interval [CI], .795-.905); to identify primary ROSC events, it was 85% (CI, .793-.907); and to identify secondary ROSC events, it was 78% (CI, .565-.995). The sensitivity of PCRs to identify the presence of all RA events was .60 (CI, .469-.731); to identify primary RA events, it was 71% (CI, .578-.842); and to identify secondary RA events, it was 0. Of the 32 RA incidents captured by the PCR, only 15 (47%) correctly identified the correct lethal arrhythmia. ConclusionsWe found that PCRs are not a reliable source of information for assessing the presence of ROSC and post-RA electrocardiogram rhythm. For quality control and research purposes, medical providers should consider augmenting data collection with continuous defibrillator recordings before making any conclusions about the occurrence of critical resuscitation events.

142 Emergency Medical Services, Injury, and Illness at the 2013 Boy Scout Jamboree

The 2013 Boy Scouts of America (BSA) National Jamboree attracted 36,261 youth, staff, and volunteers to 11,000 acres of West Virginia, a new permanent home for the BSA. All attendees camped and participated in events including mountain biking, BMX biking, skateboarding, climbing and other activities. The environment, length of event and the fact that all attendees were participants makes the Jamboree a unique challenge for Emergency Medical Services (EMS). The EMS plan involved a coordinated effort by BSA volunteers, US military, and private local EMS and air medical providers. A licensed EMS provider was established for the site: Summit EMS. State regulations were established to allow ambulance transport to temporary on-site medical facilities and to allow volunteers to practice in West Virginia. Non emergent transport capability was also provided. There were 13 Jamboree medical facilities, 2 with X-ray capability. To quantify the volume, chief complaint and destination of EMS transports at the 2013 BSA Jamboree and gain an understanding of illness and injury patterns for future events. A unified dispatch system was used to manage and track EMS resources. A combination of paper patient care reports (for military and volunteer units) and electronic run reports (for private EMS) were used. All reports were scanned into the Jamboree medical record system and a data registry was created. During 12 days of activity on the site there were 883 emergency medical services transports. Private, locally based EMS handled all off-site transports. There were 757 on site transports, 148 were by BSA EMS utility vehicle (UTV), 483 were by military field litter ambulance (FLA), 126 were by private EMS provider. There were 121 patients transported off site by ground to local hospitals. and 5 patients were transported to an on-site landing zone for helicopter transport to hospital facilities. 468 transports were related to injuries (238 extremity injuries, 230 injuries to other site), 415 transports were for medical complaints (150 heat related, 21 suspected cardiac complaints, 244 assorted medical complaints and 1 cardiac arrest). There were 347 non-emergent patients transported by van. Coordination of services between private, military and volunteer services permitted all areas to be covered with multiple possible transport methods depending on the nature and severity of complaints. There were a large percentage of non-emergent transports likely due to the terrain and geography of the site. A change in regulations permitted ambulance resources to be available for onsite and off-site transports, making more effective use of available resources and limiting the number of transports to local hospitals. There were a large number of heat-related complaints, the role and effectiveness of prevention strategies should be examined. A review of injury prevention methods should also be reviewed.

The Use of Prehospital Ketamine for Control of Agitation in a Metropolitan Firefighter-based EMS System

Introduction. Prehospital personnel frequently encounter agitated, combative, and intoxicated patients in the field. In recent years, ketamine has been described as an effective sedative agent to treat such patients; however, a paucity of research exists describing the use of prehospital ketamine. The objective of this study was to provide a descriptive analysis of the Columbus Division of Fire's experience with utilizing ketamine in the prehospital setting. We hypothesized that ketamine administration improves patient condition, is effective at sedating patients, and does not result in endotracheal intubation in the prehospital setting or in the emergency department (ED). Methods. We conducted a retrospective cohort chart review of Columbus Division of Fire patient care reports and hospital records from destination hospitals in the central Ohio region between October 2010 and October 2012. All patients receiving ketamine administered by Columbus Division of Fire personnel for sedation were included. Patients 17 years and younger were excluded. The primary outcome was the percentage of patients noted to have an “improved” condition recorded in the data field of the patient care report. The secondary outcomes were the effectiveness of sedation and the performance of endotracheal intubation. Results. A total of 36 patients met inclusion criteria over the study period. Data were available on 35 patients for analysis. The mean IV dose of ketamine was 138 mg (SD = 59.5, 100–200). The mean IM dose of ketamine was 324 mg (SD = 120, 100–500). Prehospital records noted an improvement in patient condition after ketamine administration in 32 cases (91%, 95% CI 77–98%). Six patients required sedation post-ketamine administration either by EMS (2) or in the ED (4) (17%, 95% CI 6.5–34%). Endotracheal intubation was performed in eight (23%, 95% CI 10–40%) patients post-ketamine administration. Conclusion. We found that in a cohort of patients administered ketamine, paramedics reported a subjective improvement in patient condition. Endotracheal intubation was performed in 8 patients.

Assessing pediatric and young adult substance use through analysis of prehospital data.

Substance use in young adults is a significant and growing problem. Emergency Medical Services (EMS) personnel often encounter this problem, yet the use of prehospital data to evaluate the prevalence and magnitude of substance abuse has been limited. This study evaluated drug and alcohol use through the use of prehospital and EMS data in one suburban county in Maryland (USA). The primary hypothesis was that the type of drug being abused is associated with age. The secondary hypothesis was substance abuse incidence is associated with location. The tertiary hypothesis was that substance abuse is associated with a history of mental illness. Deidentified patient care reports (PCRs) were obtained during a 24-month period from October 2010 through September 2012 for patients 0 through 25 years of age. Inclusion criteria included chief complaint of alcohol overdose, drug overdose, or the use of naloxone. The primary hypothesis was supported that age was associated with drug category (P < .001). Younger adolescents were more likely to use household items, prescription drugs, or over-the-counter drugs, whereas older adolescents were more likely to use illicit drugs. The secondary hypothesis was supported that both alcohol (P < .001) and drugs (P < .001) were associated with location of call. Calls involving alcohol were more likely to be at a home or business, whereas calls involving drugs were more likely to be at home or at a public venue. The tertiary hypothesis was supported that both alcohol (P = .001) and drug use (P < .001) were associated with history of mental illness. Older adolescents were more likely to report a history of mental illness. Chi-squared tests indicated there were significant differences between genders and drug category (P = .002) and gender and current suicide attempt (P = .004). Females were more likely to use prescription drugs, whereas males were more likely to use illicit drugs. Calls involving younger adolescents under 18 were more likely to be at school or the mall, whereas calls involving older adolescents were likely to be at a prison, public venue, or a business. All three hypotheses were supported: the type of substance being abused was associated with both age and location, and substance abuse was associated with a history of mental illness. This research has important implications for understanding how EMS resources are utilized for substance use. This information is valuable in not only the education and training of prehospital care providers, but also for the targeting of future public health interventions.

Interventional pain management skills competency in pain medicine fellows: a method for development and assessment.

The purposes of this project were to propose an educational module to instruct pain medicine fellows in the appropriate performance of interventional pain management techniques and to verify procedural competency through objective evaluation methodology. Eight board-certified pain medicine physicians spanning two fellowship programs trained seven fellows using a standardized competency-based module. Assessment tools address the basic competencies outlined by the Accreditation Council for Graduate Medical Education (American Board of Anesthesiology Pain Medicine Content Outline). The seven fellows demonstrated proficiency in every segment of the evaluation module. Objective measures compared the fellows' performance on standardized procedure checklists administered 9 mos into training; fellows in the 2012-2013 academic year also received testing at the 3-mo mark. Support for the assessment module is demonstrated by appropriate performance of interventional procedures, with improvement noted from 3-mo to 9-mo testing, successful completion of chart-stimulated oral examinations, proper performance of relevant physical examination maneuvers, and completion of program-specific medical knowledge written tests. The fellows were evaluated via patient surveys and 360-degree global rating scales, maintained procedure logs, and completed two patient-care reports; these were reviewed by program directors to ensure adequate completion. The standardized educational module and evaluation methodology presented provide a potential framework for the definition of baseline competency in the clinical skill area of interventional pain management.

Creating an infrastructure for comparative effectiveness research in emergency medical services.

Emergency medical services (EMS) providers deliver the initial care for millions of people in the United States each year. The Institute of Medicine noted a deficit in research necessary to improve prehospital care, created by the existence of data silos, absence of long-term outcomes, and limited stakeholder engagement in research. This article describes a regional effort to create a high-performing infrastructure in southwestern Pennsylvania addressing these fundamental barriers. Regional EMS records from 33 agencies in January 2011 were linked to hospital-based electronic health records (EHRs) in a single nine-hospital system, with manual review of matches for accuracy. The use of community stakeholder engagement was included to guide scientific inquiry, as well as 2-year follow up for patient-centered outcomes. Local EMS medicine stakeholders emphasized the limits of single-agency EMS research and suggested that studies focus on improving cross-cutting, long-term outcomes. Guided by this input, more than 95% of EMS records (2,675 of 2,800) were linked to hospital-based EHRs. More than 80% of records were linked to 2-year mortality, with more deaths among EMS patients with prehospital hypotension (30.5%) or respiratory distress (19.5%) than chest pain (5.4%) or nonspecific complaints (9.4%). A prehospital comparative effectiveness research infrastructure composed of patient-level EMS data, EHRs at multiple hospitals, long-term outcomes, and community stakeholder perspectives is feasible and may be scalable to larger regions and networks. The lessons learned and barriers identified offer a roadmap to answering community and policy-relevant research questions in prehospital care.

External validation of termination of resuscitation guidelines in the setting of intra-arrest cold saline, mechanical CPR, and comprehensive post resuscitation care

BackgroundThe development of advanced life support (ALS) termination of resuscitation (TOR) guidelines for out-of-hospital cardiac arrest (OHCA) seeks to improve the efficiency of scarce pre-hospital resources. However, as pre-hospital treatment for OHCA evolves and survival improves, these TOR guidelines must be reevaluated in the contemporary context of emergency medical services (EMS) providing access to advanced resuscitation care. MethodsRetrospective review of all adult (>18 years old), non-traumatic, OHCA patients (defined as patients with absence of pulse who received either CPR and/or defibrillation) treated by EMS in Richmond, VA, from January 1, 2009 to December 31, 2010. In addition to standard ALS, intra-arrest cold saline, mechanical CPR, and transportation to a comprehensive post-resuscitation center (CPRC) was provided. Patient treatment and outcomes were recorded via prehospital patient care reports and data were evaluated against previously established criteria for termination of resuscitation in an ALS EMS system. According to the aforementioned previously described criteria for TOR, patients meeting a single criterion for transport are recommended to be transported emergently to a comprehensive post-resuscitation care facility. Conversely, patients failing to meet any of the TOR criteria can be presumed to be expired without exception. Survival at 180 days was presumed when death could not be verified from publically reportable sources. ResultsOf the 322 OHCA patients enrolled, the majority were male (59%), unwitnessed (52%), received no bystander CPR (67%), and presented in a non-shockable initial rhythm (79%), with an average age of 62.5 years. Overall survival was 17%, 14%, 12%, and 11% at 7, 14, 30, and 180 days, respectively. Of the 75 patients for which TOR guidelines recommended termination, none survived yielding both 100% specificity (95% CI 100–92.8%) and positive predictive value (95% CI 100–94.1%). However, TOR guidelines recommended transport of 208 of the 283 patients who died within 30 days, resulting in a sensitivity of 26.5% (95% CI 34.5–23.4%). ConclusionThe TOR guidelines continue to have a reliable positive predictive value for death even in the setting of advanced EMS resuscitation methods and access to a CPRC. However, as the potential for survival from OHCA improves, the efficiency gained from their use is impacted greatly.

A Multiyear Analysis of the Clinical Encounters of the ATF Tactical Medical Program.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Tactical Medical Program provides tactical medical support for ATF's tactical Special Response Teams (SRTs) and investigative National Response Teams (NRTs) through the deployment of specially trained ATF Agent-Medics. All patient care activities are centrally coordinated through ATF Headquarters. A retrospective analysis of de-identified patient care reports (PCRs) from the ATF Tactical Medical Program from 2009 to 2012 was performed. Clinical and operational data were extracted from PCRs and were entered into a database by the research team. Descriptive and summative analyses were performed to assess patient type, law enforcement incident type, chief complaint, and interventions performed. Analysis was performed on the 254 charts. Nearly half (114; 44.9%) of patients encountered during the study period were law enforcement officers. High-risk warrant service was associated with one third (85; 33.5%) of the ATF medics' clinical encounters. The most common chief complaints of patients encountered were musculoskeletal pain/injury (57; 22.4%) and wounds/lacerations (57; 22.4%), followed by heat illness (17; 6.7%). The most common intervention was wound care (61; 26.9%), followed by control of bleeding with direct pressure (43; 18.9%). The most common medications administered were ibuprofen (28; 25.2%), topical antibiotic (12; 10.8%), and acetaminophen (12;10.8%). This multiyear analysis represents an important contribution to the growing body of scientific literature surrounding tactical medicine. The results of this analysis demonstrate a continued need for expanded scope of practice training, as well as enhanced treatment protocols for tactical medics.

The Implementation and Evaluation of an Evidence-based Statewide Prehospital Pain Management Protocol Developed using the National Prehospital Evidence-based Guideline Model Process for Emergency Medical Services

Background. In 2008, the National Highway Traffic Safety Administration funded the development of a model process for the development and implementation of evidence-based guidelines (EBGs) for emergency medical services (EMS). We report on the implementation and evaluation of an evidence-based prehospital pain management protocol developed using this model process. Methods. An evidence-based protocol for prehospital management of pain resulting from injuries and burns was reviewed by the Protocol Review Committee (PRC) of the Maryland Institute for Emergency Medical Services Systems (MIEMSS). The PRC recommended revisions to the Maryland protocol that reflected recommendations in the EBG: weight-based dosing and repeat dosing of morphine. A training curriculum was developed and implemented using Maryland's online Learning Management System and successfully accessed by 3,941 paramedics and 15,969 BLS providers. Field providers submitted electronic patient care reports to the MIEMSS statewide prehospital database. Inclusion criteria were injured or burned patients transported by Maryland ambulances to Maryland hospitals whose electronic patient care records included data for level of EMS provider training during a 12-month preimplementation period and a 12-month postimplementation period from September 2010 through March 2012. We compared the percentage of patients receiving pain scale assessments and morphine, as well as the dose of morphine administered and the use of naloxone as a rescue medication for opiate use, before and after the protocol change. Results. No differences were seen in the percentage of patients who had a pain score documented or the percent of patients receiving morphine before and after the protocol change, but there was a significant increase in the total dose and dose in mg/kg administered per patient. During the postintervention phase, patients received an 18% higher total morphine dose and a 14.9% greater mg/kg dose. Conclusions. We demonstrated that the implementation of a revised statewide prehospital pain management protocol based on an EBG developed using the National Prehospital Evidence-based Guideline Model Process was associated with an increase in dosing of narcotic pain medication consistent with that recommended by the EBG. No differences were seen in the percentage of patients receiving opiate analgesia or in the documentation of pain scores.

Prehospital Peripheral Intravenous Vascular Access Success Rates in Children

Objective. Achieving successful peripheral intravenous (PIV) vascular access in children can be difficult. In the prehospital setting, opportunities are rare. Obtaining access becomes vital in emergent and life-threating conditions, such as seizures, hypoglycemia, and cardiac arrest. This study examines prehospital pediatric PIV attempts, success rates, and the impact of patient age. Methods. This was a retrospective chart review of patients aged 18 years or younger receiving prehospital PIV attempts from January 1, 2003, through May 31, 2011. Included cases were identified by querying electronic patient care reports for PIV attempts within the specified age range. The documentation of PIV attempts and successes was reported by emergency medical service providers. This study was approved by an institutional review board. Results. Throughout the 101-month study period, there were 261,008 ambulance responses. PIV attempts were made in 4188 patients aged 18 years or younger. PIV placement was successful in 3699 patients (88.3%) and failed in 489 (11.7%). Age was significantly associated with success. Each 1-year increase in age was associated with an 11% increase in odds of PIV success (odds ratio, 1.11; 95% CI, 1.09–1.12; p < 0.001). Success was lowest in patients younger than 2 years old, with an overall success rate of 64.1% (141/220). Accounting for multiple attempts, success was achieved in 53.0% of attempts (141/266). Conclusions. Prehospital PIV attempts are uncommon (2% of emergent responses). Success rates are significantly associated with patient age in the pediatric population and lowest in those aged 2 years or less. Consideration of alternative forms of vascular access in this population may be beneficial. Key words: ambulance; emergency medical services; intraosseous; intravenous; pediatric
