Decreased Time from 9-1-1 Call to PCI among Patients Experiencing STEMI Results in a Decreased One Year Mortality

Background: The impact on mortality due to prompt recognition of ST-segment Elevation Myocardial Infarction (STEMI) patients by EMS has not been well described. The objective of this study was to describe the association between the time interval, 9-1-1 call to percutaneous intervention (PCI), and mortality at one year. Methods: This retrospective analysis included patients that were transported by EMS as a “code STEMI” and underwent PCI. Total time from 9-1-1 call to PCI was calculated for each patient and was the independent variable of interest. Each patient's mortality status at one year was the outcome variable, collected by querying medical records and the national death index. Confounding variables were abstracted from hospital records. Logistic regression was conducted to determine the likelihood of survival given differences in time to PCI. Results: A total of 550 patients were included in the analyses of which 68% were male with an average age 59.8 (SD 12.8). Mean reperfusion time was 81.8 min (SD 20.0) and was significantly lower in patients alive at one year (80.8 min, SD 19.7) vs. deceased at one year (93.9 min, SD 19.6), respectively. Odds of survival at one year decreased by 3% (OR 0.97; 95% CI 0.96–0.99) for every one minute increase in time to PCI. This relationship practically represents a 30% increase in mortality for every 10 minute delay from 9-1-1 call to PCI. Conclusion: The model produced suggests that a linear relationship exists between time to PCI and mortality in the prehospital environment with the probability of survival decreasing significantly as time to PCI increases.     

Accuracy of weight estimates in pediatric patients by prehospital Emergency Medical Services personnel

Objectives

Most medications administered to children are weight-based, and inaccurate weight estimation may contribute to medical errors. Previous studies have been limited to hypothetical patients and those in cardiopulmonary arrest. We aim to determine the accuracy of weight estimates by Emergency Medical Services (EMS) personnel of children receiving medications and to identify factors associated with accuracy.

Methods

EMS records of children < 18 years old receiving weight-based medications were merged with EMS staffing data and hospital records. The rate of accurate weight estimates, defined as a value within 20% of the actual weight, was evaluated as the primary outcome. Factors associated with patients and prehospital personnel were also evaluated.

Results

29 233 transports occurring during the study period were reviewed, and 199 transports of 179 children were analyzed. The average experience of EMS personnel was 35.8 months (SD ± 30.7). EMS personnel accurately estimated weights in 164/199 (82.4%) patients; estimated weights were within 10.8% (SD ± 10.5) of the actual weights. Underestimated weights were associated with receiving doses outside of the therapeutic range. Inaccurate weight estimates were associated with age less than 10 years or cardiopulmonary arrest. There was a trend toward inaccurate weight estimates among children who presented with seizures.

Conclusions

EMS personnel are generally accurate in estimating weights of children. There was an association between underestimated weights and inaccurate medication dosing. Younger children or those presenting with seizure or cardiopulmonary arrest were more likely to have inaccurate weight estimates.     

Pediatric Use of Emergency Medical Services: The Role of Chronic Illnesses and Behavioral Health Problems

Objective: The increasing use of prehospital emergency medical services (EMS) and its contribution to rising emergency department use and healthcare costs point to the need for better understanding factors associated with EMS use to inform preventive interventions. Understanding patient factors associated with pediatric use of EMS will inform pediatric-specific intervention. We examined pediatric patient demographic and health factors associated with one-time and repeat use of EMS. Methods: We reviewed data from Baltimore City Fire Department EMS patient records over a 23-month period (2008–10) for patients under 21 years of age (n = 24,760). Repeat use was defined as involvement in more than one EMS incident during the observation period. Analyses compared demographics of EMS users to the city population and demographics and health problems of repeat and one-time EMS users. Health comparisons were conducted at the patient and incident levels of analysis. Results: Repeat users (n = 1,931) accounted for 9.0% of pediatric users and 20.8% of pediatric incidents, and were over-represented among the 18–20 year age group and among females. While trauma accounted for approximately one-quarter of incidents, repeat versus one-time users had a lower proportion of trauma-related incidents (7.2% vs. 26.7%) and higher proportion of medical-related incidents (92.6% vs. 71.4%), including higher proportions of incidents related to asthma, seizures, and obstetric/gynecologic issues. In patient-level analysis, based on provider or patient reports, greater proportions of repeat compared to one-time users had asthma, behavioral health problems (mental, conduct and substance use problems), seizures, and diabetes. Conclusions: Chronic somatic conditions and behavioral health problems appear to contribute to a large proportion of the repeat pediatric use of this EMS system. Interventions may be needed to engage repeat users in primary care and behavioral health services, to train EMS providers on the recognition and management of behavioral health emergencies, and to improve family care and self-management of pediatric asthma and other chronic conditions.     

P REHOSPITAL C ARE R ESEARCH F ORUM /NAEMSE 2002

Objectives. Emergency medical dispatch (EMD) protocols are intended to match response resources with patient needs. In a small city that previously sent a first-responder basic life support (BLS) engine company lights-and-siren response to every emergency medical services (EMS) call, regardless of nature or severity, an EMD system was implemented in order to reduce the number of such responses. The study objectives were to determine the effects of the EMD system on first-responder call volume andto assess the safety of the system. Methods. This was a prospective, before–after trial. Using computer-assisted dispatch (CAD) records, all EMS calls in the 120 days before implementation of the EMD protocol andthe 120 days after implementation were identified (excluding a one-month wash-in period). In the “after” phase, patient care reports of a random sample of cases in which an ambulance was dispatched with no first responders was manually reviewed to assess whether there might have been any benefit to first-responder dispatch. Given the lack of accepted clinical criteria for need for first responders, the investigators' clinical judgment was used. Paired t-tests were used to compare groups. Results. There were 9,820 EMS calls in the “before” phase, with 8,278 first-responder engine runs (84.3%), and9,943 EMS calls in the “after” phase, with 3,804 first-responder engine runs (39.1%). The first-responder companies were dispatched to a median of 5.65 runs/day (range 1.1–12.7) in the “before” phase, and3.17 runs/day (range 0.6–5.0) in the “after” phase (p = 0.0008 by paired t-test). Review of 1,816 “after” phase ambulance-only patient care reports (PCRs) found ten (0.55%) in which first-responder dispatch might have been beneficial, but review of EMS andemergency department (ED) records found no adverse outcomes in these ten patients. Conclusions. This study suggests that a formal EMD system can reduce first-responder call volume by roughly one-half. The system appears to be safe for patients, with an undertriage rate of about one-half of one percent.     

Reasons 9-1-1 Is Called for Cardiac Arrest Cases in Which No Resuscitation Is Attempted

Objective. The goal of this investigation was to describe the reasons emergency medical services (EMS) is activated when resuscitation is not desired or when patients show signs of irreversible death. Methods. All medical incident report forms (MIRFs) indicating a cardiac arrest for which resuscitation was withheld were obtained from five participating fire departments. For each eligible case (N = 196), one of the emergency medical technicians (EMTs) present at the scene was interviewed and the dispatch tape of the 9-1-1 call was reviewed. Patient and caller characteristics were abstracted from the MIRFs and dispatch tapes. The EMTs were asked about the reasons for the call, whether the family expected this death, and the caller's emotional state when EMS arrived at the scene. In addition, EMS providers were asked open-ended questions about the services they provided for the patient and patient's family. Using chi-square statistics and t-tests, we compared two groups: 1) patients for whom resuscitation was not desired as indicated by a do-not-resuscitate (DNR) order, terminal illness, or hospice (n = 66) and 2) patients for whom resuscitation was not started because of signs of irreversible death (n = 130). Results. Compared with callers for patients with signs of irreversible death, callers for patients for whom resuscitation was not desired were less likely to access EMS because they needed medical assistance (11% versus 30%) and more likely to call 9-1-1 because they thought it was “required by law” (30% versus 8%). Other common reasons in both groups for activating 9-1-1 were confusion regarding what to do and a request to confirm death. The most frequently reported service provided by EMTs for both groups was to “offer to contact a chaplain.” Conclusion. In a third of patients for whom EMS did not initiate resuscitation, resuscitation was withheld primarily because it was not desired rather than because there was evidence of irreversible death. Efforts to improve education may prevent EMS activation in these cases. An alternative EMS response could also help ensure patient autonomy and decrease costs to the EMS system.     

The Ability of Emergency Medical Dispatch Codes of Medical Complaints to Predict ALS Prehospital Interventions

Objective. The Medical Priority Dispatch System (MPDS) is an emergency medical dispatch (EMD) system that is commonly used to triage 9-1-1 calls andoptimize paramedic andEMT dispatch. The objective of this study was to determine the sensitivity, specificity, andpositive andnegative predictive values of selected MPDS dispatch codes to predict the need for ALS medication or procedures. Methods. Patients with selected MPDS codes between November 1, 2003, andOctober 31, 2005, from a suburban California county were matched with their electronic patient care record. The records of all transported patients were queried for prehospital interventions andmatched to their MPDS classification [Basic Life Support (BLS) versus Advanced Life Support (ALS)]. Patients who received prehospital interventions or medications were considered ALS Intervention. With true positive = ALS by MPDS + ALS Intervention, true negative = BLS by MPDS + BLS Interventions, false positive = ALS by MPDS + BLS Interventions, andfalse negative = BLS by MPDS + ALS Interventions, the screening performance of the San Mateo County EMD system was determined for selected complaint categories (abdominal pain, breathing problems chest pain, sick person, seizures, andunconscious/fainting). Results. There were a total of 64,647 medical calls, and42,651 went through the EMD process; 31,187 went through the EMD process andwere transported; 22,243of these were matched to a patient care record. The sensitivity andspecificity with 95% confidence intervals in () were as follows: all EMD calls 84 (83–85), 36 (35–36); abdominal pain, 53 (41–65), 47 (43–51); chest pain 99 (99–100), 2 (1–3); seizure 83 (77–88), 20 (17–23), sick 59 (53–64), 51 (49–54), andunconscious/fainting 99 (98–100), 2 (2–3). Conclusion. In our EMS system, MPDS coding for all medical calls had high sensitivity andlow specificity for the prediction of calls that required ALS intervention. Chest pain andunconscious/fainting calls were screened with very high sensitivity but very low specificity.     

Ability of the Physiologic Criteria of the Field Triage Guidelines to Identify Children Who Need the Resources of a Trauma Center

Background: There is limited research on how well the American College of Surgeons/Center for Disease Control and Prevention Guidelines for Field Triage of Injured Patients assist EMS providers in identifying children who need the resources of a trauma center. Objective: To determine the accuracy of the Physiologic Criteria (Step 1) of the Field Triage Guidelines in identifying injured children who need the resources of a trauma center. Methods: EMS providers who transported injured children 15 years and younger to pediatric trauma centers in 3 mid-sized cities were interviewed regarding patient demographics and the presence or absence of each of the Field Triage Guidelines criteria. Children were considered to have needed a trauma center if they had non-orthopedic surgery within 24 hours, ICU admission, or died. This data was obtained through a structured hospital record review. The over- and under-triage rates and positive likelihood ratios (+LR) were calculated for the overall Physiologic Criteria and each individual criterion. Results: Interviews were conducted for 5,610 pediatric patients; outcome data were available for 5,594 (99.7%): 5% of all patients needed the resources of a trauma center and 19% met the physiologic criteria. Using the physiologic criteria alone, 51% of children who needed a trauma center would have been under-triaged and 18% would have been over-triaged (+LR 2.8, 95% CI 2.4–3.2). Glasgow Coma Score (GCS) < 14 had a +LR of 14.3 (95% CI 11.2–18.3), with EMS not obtaining a GCS in 4% of cases. 54% of those with an EMS GCS < 14 had an initial ED GCS < 14. Abnormal respiratory rate (RR) had a +LR of 2.2 (95% CI 1.8–2.6), with EMS not obtaining a RR in 5% of cases. 41% of those with an abnormal EMS RR had an abnormal initial ED RR. Systolic blood pressure (SBP) < 90 had a +LR of 3.5 (95% CI 2.5–5.1), with EMS not obtaining a SBP in 20% of cases. SBP was not obtained for 79% of children <1 year, 46% 1–4 years, 7% 5–9 years, and 2% 10–15 years. A total of 19% of those with an EMS SBP < 90 had an initial ED SBP < 90. Conclusions: The Physiologic Criteria are a moderate predictor of trauma center need for children. Missing or inaccurate vital signs may be limiting the predictive value of the Physiologic Criteria.     

Simulation-based Assessment of Paramedic Pediatric Resuscitation Skills

Background. Emergency medical services (EMS) providers infrequently encounter seriously ill and injured pediatric patients. Clinical simulations are useful for assessing skill level, especially for low-frequency, high-risk problems. Objective. To identify the most common performance deficiencies in paramedics' management of three simulated pediatric emergencies. Methods. Paramedics from five EMS agencies in Michigan were eligible subjects for this prospective, observational study. Three clinical assessment modules (CAMs) were designed and validated using pediatric simulators with varying technologic complexity. Scenarios included an infant cardiopulmonary arrest, sepsis/seizure, and child asthma/respiratory arrest. Each scenario required paramedics to perform an assessment and provide appropriate pediatric patient care within a 12-minute time limit. Trained instructors conducted the simulations by following strict guidelines for sequences of events and responses. Videos of CAMs were reviewed by an independent evaluator to verify scoring accuracy. Percentage of steps completed for each of the three scenarios and specific performance deficiencies were recorded. Results. Two hundred twelve paramedics completed the CAMs. The average percentages of steps completed were as follows: arrest CAM, 45.3%; asthma CAM, 51.6%; and sepsis CAM, 47.1%. Performance deficiencies included lack of airway support or protection; lack of support of ventilations or cardiac function; inappropriate use of length-based treatment tapes; and inaccurate calculation and administration of medications and fluids. Conclusion. Multiple deficiencies in paramedics' performance of pediatric resuscitation skills were objectively identified using three manikin-based simulations. EMS educators and EMS medical directors should target these specific skill deficiencies when developing continuing education in prehospital pediatric patient care.     

E MERGENT F IELD M EDICINE

Abstract

Objective. We sought to categorize and characterize the utilization of statewide emergency medical services (EMS) protocols as well as state recognition of specialty receiving facilities for trauma and time-sensitive conditions in the United States. Methods. A survey of all state EMS offices was conducted to determine which states use mandatory or model statewide EMS protocols and to characterize these protocols based on the process for authorizing such protocols. The survey also inquired as to which states formally recognize specialty receiving facilities for trauma, STEMI, stroke, cardiac arrest, and burn as well as whether or not states have mandatory or model statewide destination protocols for these specialty centers. Results. Thirty-eight states were found to have either mandatory or model statewide EMS protocols. Twenty-one states had mandatory statewide EMS protocols at either the basic life support (BLS) or advanced life support (ALS) level, and in 16 of these states, mandatory protocols covered both BLS and ALS levels of care. Seventeen states had model statewide protocols at either the BLS or ALS level, and in 14 of these states, the model protocols covered both BLS and ALS levels of care. Twenty states had separate protocols for the care of pediatric patients, while 18 states combined pediatric and adult care within the same protocols. When identified, the median age used to consider a patient for pediatric care was ≤14 years (range ≤8 to ≤17 years). Three states’ protocols used a child's height based on a length-based dosage tool as the threshold for identifying a pediatric patient for care using their pediatric protocols. States varied in recognition of receiving centers for EMS patients with special medical needs: 46 recognized trauma centers, 25 recognized burn centers, 22 recognized stroke centers, 11 recognized centers capable of percutaneous coronary intervention for ST-elevation myocardial infarction, and 3 recognized centers for patients surviving cardiac arrest. Conclusion. Statewide mandated EMS treatment protocols exist in 21 states, and optional model protocol guidelines are provided by 17 states. There is wide variation in the format and characteristics of these protocols and the recognition of specialty receiving centers for patients with time-sensitive illnesses.     

Epidemiology of Pediatric Transports andNon-Transports in an Urban Emergency Medical Services System

Objective. This study was done to describe an urban, Emergency Medical Service (EMS) system's experiences with pediatric patients andthe rate andcharacteristics of non-transports in this setting. Methods. A retrospective analysis of all pediatric patients responded to by the Detroit Fire Department Division of EMS between January 1, 2002 andAugust 30, 2002 was done. Results. There were 5,976 pediatric EMS cases. Children 10 years of age or older accounted for 49.4% of transports, 53.8% of all patients had medical illness, and38.8% of the patients belonged to the non-urgent category. A large percentage of patients were not transported (27.2%), most commonly secondary to parent/caregiver/patient refusals. The median number of minutes on-scene for refusals was longer than for transports (23.5 vs. 17.3, respectively)[difference = 6.2 minutes (95% CI: 5.6–6.9)]. The odds ratios (OR) for refusal was highest for assaults (2.09; 95% CI: 1.66–2.63), difficulty in breathing (1.38; 95% CI: 1.14–1.68), andmotor vehicle accidents (1.19; 95% CI: 1.04–1.37). Conclusions. In this system, the majority of pediatric patients are not severely ill, anda large number are not transported. Non-transports are more likely to be young adolescents, have been involved in assaults, andhave a longer on-scene time.     

Paramedic Initiated Non-Transport of Pediatric Patients

Introduction. In a time of emergency department overcrowding andincreased utilization of emergency medical services, a highly functional prehospital system will balance the needs of the individual patient with the global needs of the community. Our community addressed these issues through the development of a multitiered prehospital care system that incorporated EMS initiated non-transport of pediatric patients. Objective. To describe the outcome of pediatric patients accessing a progressive prehospital system that employed EMS initiated non-transport. Methods. A prospective observational case series was performed on pediatric patients (< 21 years old) designated EMS initiated non-transport. Patients were designated non-transport after an initial EMS protocol driven, complaint-specific clinical assessment in conjunction with medical oversight affirmation. Telephone follow-up was completed on all consecutively enrolled non-transport patients to collect information about outcome (safety) as well as overall satisfaction with the system. A five-point Likert scale was utilized to rate satisfaction. Results. There were 5,336 EMS requests during the study period. Seven hundred andfour were designated non-transport, of which 74.8% completed phone follow-up. Categories of EMS request included minor; medical illness 43.4%, trauma 55.9%, andother 1.1%. There were 13 admissions (2.4%) to the hospital after EMS initiated non-transport designation. Admissions after non-transport had trends toward younger age (p = 0.002) andmedical etiology (p = 0.006). There were no PICU admissions or deaths. Conclusion. Our EMS system provides an alternative to traditional protocols, allowing EMS initiated non-transport of pediatric patients, resulting in effective resource utilization with a high level of patient safety andfamily satisfaction.     

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.     

EMS Providers' Beliefs Regarding Spinal Precautions for Pediatric Trauma Transport

Objective: Describe prehospital Emergency Medical Services (EMS) providers' beliefs regarding spinal precautions for pediatric trauma transport. Methods: We randomly surveyed nationally certified EMS providers. We assessed providers' beliefs about specific precautions, and preferred precautions given a child's age (0–4 or 5–18 years) and presence of specific cervical spine injury (CSI) risk factors. Results: We received 5,400 responses (17%). Most were Paramedics (36%) or EMTs (22%) and worked at fire-based services (42%). A total of 47% endorsed responding to pediatric calls more than once per month. Consensus beliefs (>66% agreement) were that rigid cervical collars (68%) and long backboards with soft conforming surfaces (79%) maintain an injured pediatric spine in optimal position. Only 39% believed in the utility of the rigid long backboard to protect the pediatric spine. For most risk factors in both age categories, a rigid cervical collar with a long backboard with a soft conforming surface was the most common response (28–40% depending on age group and risk factor); however, there were no consensus beliefs. Provider-level experience, working as a patient care provider, less education, and parent status were associated with endorsing the rigid cervical collar. Factors associated with endorsing the rigid long backboard included provider level, working as a patient care provider, low pediatric call volume, and less education. Conclusions: EMS providers believe that rigid cervical collars and long backboards with soft conforming surfaces provide optimal spinal precautions. There were no consensus beliefs, however, for use of particular precautions based on age and risk factors.     

The effect of a curfew on pediatric out-of-hospital ems responses

Objective. The purpose of a curfew is to decrease the amount of crime inflicted on minors during the late hours of the night. On June 1, 1994, a city curfew was instituted in New Orleans, requiring all persons 17 years of age or younger to be off the streets from 9 pm to 6 am Sunday through Thursday, and from 11 pm to 6 am on Friday and Saturday. This study evaluated the effect of the curfew on emergency medical services (EMS) transports for patients who were 17 years old or younger (pediatric). Methods. Data from all pediatric transports were included from the months before (5/94) and after (6/94) the institution of the curfew, and from the same two months one year earlier (5/93 and 6/93). A chi-square test was used to evaluate comparisons. Results. The city EMS transports 48,000 patients per year in a one-tiered system (paramedic only) that acts as the sole provider of emergency EMS transport in the city. Approximately 10% of all transports are pediatric, and 40% of the pediatric transports are for trauma. A total of 1,642 transports were found that fit the inclusion criteria. In May 1993, there were 415 total pediatric transports; 234 were pediatric trauma. In June 1993, there were 406 total pediatric transports; 250 were pediatric trauma. In May 1994, there were 447 total pediatric runs; 243 were pediatric trauma. During the postcurfew month, June 1994, there were a significant decrease in pediatric transports to 370 (p < 0.01) and a significant decrease in pediatric trauma transports to 189 (p < 0.01). Conclusion. The institution of a curfew may lead to a drop in pediatric EMS runs during curfew hours. Another value of the curfew may be in the secondary effects of the curfew in preventing childhood injury during noncurfew hours.     

Can Altering Grip Technique and Bag Size Optimize Volume Delivered with Bag-Valve-Mask by Emergency Medical Service Providers?

Introduction: Emergency Medical Services (EMS) professionals rely on the bag-valve-mask (BVM) to provide life-saving positive-pressure ventilation in the prehospital setting. Multiple emergency medicine and critical care studies have shown that lung-protective ventilation protocols reduce morbidity and mortality. A recent study has shown that the volumes typically delivered by EMS professionals with the adult BVM are often higher than recommended by lung-protective ventilation protocols. Our primary objective was to determine if a group of EMS professionals could reduce the volume delivered by adjusting the way the BVM was held. Secondary objectives included 1) if the adjusted grip allowed for volumes more consistent with lung-protection ventilation strategies and 2) comparing volumes to similar grip strategies used with a smaller BVM. Methods: A patient simulator of a head and thorax was used to record respiratory rate, tidal volume, peak pressure, and minute volume delivered by participants for 1?minute each across 6 different scenarios: 3 different grips (using the thumb and either 3 fingers, 2 fingers, or one finger) with 2 different sized BVMs (adult and pediatric). Trials were randomized by blindly selecting a paper with the scenario listed. A convenience sample of EMS providers was used based on EMS provider and research staff availability. Results: We enrolled 50 providers from a large, busy, urban hospital-based EMS agency a mean 8.60 (SD = 9.76) years of experience. Median volumes for each scenario were 836.0?mL, 834.5?mL, and 794?mL for the adult BMV (p?=?0.003); and 576.0?mL, 571.5?mL, and 547.0?mL for the pediatric BVM (p?<?0.001). Across all 3 grips, the pediatric BVM provided more breaths within the recommended volume range for a 70?kg patient (46.4% vs. 0.4%; p?<?0.001) with only a 1.1% of breaths below the recommended tidal volume. Conclusion: The study suggests that it is possible to alter the volume provided by the BVM by altering the grip on the BVM. The tidal volumes recorded with the pediatric BVM were above recommended range in 2 of the 3 grips. The volumes of the pediatric BVM were overall more consistent with lung-protective ventilation volumes when compared to all 3 finger-grips of the adult BVM.     

Out-of-Hospital Pediatric Patient Safety Events: Results of the CSI Chart Review

Objective: Studies of adult hospital patients have identified medical errors as a significant cause of morbidity and mortality. Little is known about the frequency and nature of pediatric patient safety events in the out-of-hospital setting. We sought to quantify pediatric patient safety events in EMS and identify patient, call, and care characteristics associated with potentially severe events. Methods: As part of the Children's Safety Initiative -EMS, expert panels independently reviewed charts of pediatric critical ambulance transports in a metropolitan area over a three-year period. Regression models were used to identify factors associated with increased risk of potentially severe safety events. Patient safety events were categorized as: Unintended injury; Near miss; Suboptimal action; Error; or Management complication (“UNSEMs”) and their severity and potential preventability were assessed. Results: Overall, 265 of 378 (70.1%) unique charts contained at least one UNSEM, including 146 (32.8%) errors and 199 (44.7%) suboptimal actions. Sixty-one UNSEMs were categorized as potentially severe (23.3% of UNSEMs) and nearly half (45.3%) were rated entirely preventable. Two factors were associated with heightened risk for a severe UNSEM: (1) age 29 days to 11 months (OR 3.3, 95% CI 1.25-8.68); (2) cases requiring resuscitation (OR 3.1, 95% CI 1.16-8.28). Severe UNSEMs were disproportionately higher among cardiopulmonary arrests (8.5% of cases, 34.4% of severe UNSEMs). Conclusions: During high-risk out-of-hospital care of pediatric patients, safety events are common, potentially severe, and largely preventable. Infants and those requiring resuscitation are important areas of focus to reduce out-of-hospital pediatric patient safety events.
