Defining priorities for emergency medical services education research: A modified Delphi study.

Objective: As out-of-hospital medicine evolves, emergency medical services (EMS) education practices must also be updated to ensure that EMS professionals acquire and maintain the skills needed to best serve patients. We aimed to identify and rank the top 10 research priorities related to EMS education in the United States. Methods: We conducted a convenience survey of EMS educators to identify challenges facing EMS education before leveraging a purposefully selected panel of EMS educators to prioritize research gaps through a modified Delphi approach. Data were collected electronically (March 2021-June 2021) over 4 survey rounds consisting of idea generation (Rounds 1 and 2), importance scoring (Round 3), and consensus ranking (Round 4). At the end of Round 4, composite scores were used to generate a list of 10 prioritized research gaps related to EMS education. Results: In the pre-Delphi survey, 463 EMS educators identified 2055 challenges facing EMS education. We recruited 32 EMS education experts as Delphi panelists and 28 completed all 4 rounds. Panelists submitted 77 knowledge gaps. The top 10 knowledge gaps included defining competency of EMS learners and educators, association of curricula and accreditation requirements with real-world practice, the effects of diversity and cultural humility among educators and learners on equitable patient care, evidence-based teaching methods, and public perception of the EMS profession and education system. Conclusions: Although 10 gaps were prioritized, panelists deemed all 77 gaps as having considerable importance for EMS education. This suite of knowledge gaps is intended to guide researchers and research-funding bodies for future resource allocation.

Reduced Emergency Department Length of Stay and Proportion of Patients Who Left Without Being Seen Following Implementation of an Interprofessional Vertical Flow Track With Pivot Triage: A Retrospective Pre-/Postintervention Evaluation.

Our objective was to assess change in length of stay and patients who left without being seen following implementation of a pivot triage and interprofessional vertical flow track process at a midwestern academic medical center emergency department. The intervention leveraged an existing interprofessional staffing model including a registered nurse and a paramedic to staff a vertical flow track daily from 1100 to 2300. Pre- and postintervention data were retrospectively abstracted from the electronic charting software. Outcomes included emergency department length of stay and percentage of patients leaving without being seen. Visits for patients during the postintervention period (May 10, 2019, to August 31, 2019) were compared with a corresponding preintervention time period 1 year prior (May 10, 2018, to August 31, 2018). The percentage of patients routed to the vertical flow track increased from 5% to 22% following the process intervention. Median emergency department length of stay decreased from 199 (interquartile range [IQR]: 129-282) to 159 (IQR: 98-232) min. The percentage of patients leaving without being seen decreased from 2.9% to 0.5%; between 1100 and 2300, these changes were more pronounced. Odds of a patient experiencing emergency department length of stay under 180 min increased nearly twofold (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.79-2.08) and odds that a patient stayed to be seen by a medical professional increased sixfold (OR: 5.94, 95% CI: 4.08-8.63). Overall, more than 20% of patients were routed through the vertical flow track following the process change. Implementation of an emergency department pivot triage approach with a dedicated interprofessional vertical flow track was associated with significantly shorter emergency department length of stay and reduced patients leaving without being seen.

Emergency medical services education research priorities during COVID-19: A modified Delphi study.

OBJECTIVE: Our objective was to identify research priorities to understand the impact of COVID-19 on initial emergency medical services (EMS) education. METHODS: We used a modified Delphi method with an expert panel (n = 15) of EMS stakeholders to develop consensus on the research priorities that are most important and feasible to understand the impact of the COVID-19 pandemic on initial EMS education. Data were collected from August 2020 to February 2021 over 5 rounds (3 electronic surveys and 2 live virtual meetings). In Round 1, participants submitted research priorities over 9 specific areas. Responses were thematically analyzed to develop a list of research priorities reviewed in Round 2. In Round 3, participants rated the priorities by importance and feasibility, with a weighted score (2/3*importance+1/3*feasibility) used for preliminary prioritization. In Round 4, participants ranked the priorities. In Round 5, participants provided their agreement or disagreement with the group's consensus of the top 8 research priorities. RESULTS: During Rounds 1 and 2, 135 ideas were submitted by the panel, leading to a preliminary list of 27 research priorities after thematic analysis. The top 4 research priorities identified by the expert panel were prehospital internship access, impact of lack of field and clinical experience, student health and safety, and EMS education program availability and accessibility. Consensus was reached with 10/11 (91%) participants in Round 5 agreeing. CONCLUSIONS: The identified research priorities are an important first step to begin evaluating the EMS educational infrastructure, processes, and outcomes that were affected or threatened through the pandemic.

Prevalence of Unique Pediatric Pathologies Encountered by Paramedic Students Across Age Groups.

UNLABELLED: Introduction Traditionally, Emergency Medical Services (EMS) educators have divided the pediatric population into age groups to assist in targeting their clinical and didactic curriculum. Currently, the accrediting body for paramedic training programs requires student exposure to pediatric patients based entirely on age without specifying exposure to specific pathologies within each age stratification. Identifying which pathologies are most common within the different pediatric age groups would allow educators to design curriculum targeting the most prevalent pathologies in each age group and incorporating the physiologic and psychological developmental milestones commonly seen at that age. Hypothesis It was hypothesized that there are unique clusterings of pathologies, represented by paramedic student primary impressions, that are found in different age groups which can be used to target provider education. METHODS: This is a retrospective review of prospectively collected data documented by paramedic students in the Fisdap (Field Internship Student Data Acquisition Project; Saint Paul, Minnesota USA) database over a one-year period. For the purposes of this study, pediatric patients were defined arbitrarily as those between the ages of 0-16 years. All paramedic student primary impressions recorded in Fisdap for patients aged 0-16 years were abstracted. Primary impression by age was calculated and graphed. The frequency of primary impression was then assessed for significance of trend by age with an alpha ≤.05 considered significant. RESULTS: The following primary impressions showed clinically and statistically significant variability in prevalence among different pediatric age groups: respiratory distress, medical-other, abdominal pain, seizure, overdose/poisoning, behavioral, and cardiac. In patients less than 13 years old, respiratory and other-medical were the most common two primary impressions and both decreased with age. In patients 5-16 years old, the prevalence of abdominal pain and behavioral/psych increased. Bimodal distributions for overdose were seen with one spike in the toddler and another in the adolescent population. Seizures were most common in the age group associated with febrile seizure. Sepsis was seen most often in the youngest patients and its prevalence decreased with age. CONCLUSION: There are statistically significant variations in the frequency of paramedic student primary impressions as a function of age in the pediatric population. Emphasizing paramedic student exposure to the most common pathologies encountered in each age group, in the context of the psychological and physiological milestones of each age, may improve paramedic student pediatric practice.

Achieving a Safe Endotracheal Tube Cuff Pressure in the Prehospital Setting: Is It Time to Revise the Standard Cuff Inflation Practice?

Numerous studies have reported unsafe endotracheal tube (ETT) cuff pressures (CP) in the prehospital environment. The purpose of this study was to identify an optimal cuff inflation volume (CIV) to achieve a safe CP (20-30 cmH2O). This observational study utilized 30 recently harvested ovine tracheae, which were warmed from refrigeration in a water bath at 85°F prior to testing. Each trachea was intubated with five different ETT sizes (6.0-8.0 mm), and each size tube was tested with six cuff inflation volumes (5-10 cc). The order of ETT size for each trachea and CIV for each size ETT was randomly pre-assigned. Data were descriptively summarized and categorized before mixed-effects logistic regression was used to determine optimal CIV. Only 113 CP measurements (12.6%, N = 900) were within the optimal range (M = 54.75 cmH2O, SD = 38.52), all of which resulted from a CIV 6 or 7 cc (61% and 39%, respectively). CIVs of 5 cc (n = 150) resulted in underinflation (<20 cmH2O) in all instances, while CIVs of 8, 9, or 10 cc (n = 150 each) resulted in overinflation (>30 cmH2O) in all instances, regardless of ETT size. The odds of achieving a safe CP were greater with CIV of 6 cc for tube sizes 6.0 (OR = 15.9, 95% CI = 3.85-65.58, p < 0.01) and 6.5 mm (OR = 3.16, 95% CI = 1.06-9.39, p = 0.039); however, there was no significant difference in the odds of achieving a safe CP between CIV of 6 and 7 cc for tube sizes 7.0, 7.5, or 8.0 mm. Neither trachea circumference (M = 7.11 cm, SD = 0.40), nor tissue temperature (M = 81.32°F, SD = 0.93) were found to be significant predictors of CP (p = 0.20 and 0.81, respectively). Our study showed a high frequency of CP measurements outside of the desired norms. The CIV range of 6-7 cc resulted in the highest likelihood of achieving the desired cuff pressure range, while cuffs inflated with 8-10 cc resulted in dangerously high CPs in all instances. In the absence of a more ideal solution, the results of this study suggest that narrowing the recommended CIV from 5-10 cc to 6-7 cc might be a reasonable target for any tube size.

Simulation Use in Paramedic Education Research (SUPER): A Descriptive Study.

OBJECTIVES: The purpose of this research was to characterize the use of simulation in initial paramedic education programs in order assist stakeholders' efforts to target educational initiatives and resources. This group sought to provide a snapshot of what simulation resources programs have or have access to and how they are used; faculty perceptions about simulation; whether program characteristics, resources, or faculty training influence simulation use; and if simulation resources are uniform for patients of all ages. METHODS: This was a cross-sectional census survey of paramedic programs that were accredited or had a Letter of Review from the Committee on Accreditation of Educational Programs for the EMS Professions at the time of the study. The data were analyzed using descriptive statistics and chi-square analyses. RESULTS: Of the 638 surveys sent, 389 valid responses (61%) were analyzed. Paramedic programs reported they have or have access to a wide range of simulation resources (task trainers [100%], simple manikins [100%], intermediate manikins [99%], advanced/fully programmable manikins [91%], live simulated patients [83%], computer-based [71%], and virtual reality [19%]); however, they do not consistently use them, particularly advanced (71%), live simulated patients (66%), computer-based (games, scenarios) (31%), and virtual reality (4%). Simulation equipment (of any type) reportedly sits idle and unused in (31%) of programs. Lack of training was cited as the most common reason. Personnel support specific to simulation was available in 44% of programs. Programs reported using simulation to replace skills more frequently than to replace field or clinical hours. Simulation goals included assessment, critical thinking, and problem-solving most frequently, and patient and crew safety least often. Programs using advanced manikins report manufacturers as their primary means of training (87%) and that 19% of faculty had no training specific to those manikins. Many (78%) respondents felt they should use more simulation. CONCLUSIONS: Paramedic programs have and have access to diverse simulation resources; however, faculty training and other program resources appear to influence their use.

Prehospital oxygen administration for chest pain patients decreases significantly following implementation of the 2010 AHA guidelines.

OBJECTIVES: The purpose of this study was to examine trends in oxygen administration following the 2010 American Heart Association guidelines recommendation to withhold oxygen therapy for patients with uncomplicated presentations of ACS whose SpO2 is 94% or higher. METHODS: Following IRB review and approval, we performed a retrospective analysis of data obtained from Fisdap(TM), a national, clinical skills tracking system for paramedic students between June 2010 and December 2012. Inclusion criteria included: 1) student consent for research, 2) cardiac chest pain recorded as the chief complaint, and 3) SpO2 data available for review. O2 administration, route, and dose were abstracted, and the percent of patient encounters with oxygen administration was calculated for each year. Unadjusted logistic regression was used to determine if O2 administration rates changed significantly over the study period. Unadjusted logistic regression was also used to determine if there was a difference in the odds of receiving oxygen based on a patient's SpO2 value. RESULTS: 10,552 patient encounters by 2,447 paramedic students from 195 paramedic programs representing 49 states were included for analysis. Prior to release of the new guidelines (2010), 71.9% (95% CI 69.8-74.0%) of patients with SpO2 ≥ 94% received supplemental O2. Rates of O2 administration were significantly lower in 2011 (64%; 95% CI 62.7-65.3%) and in 2012 (53.1%; 95% CI 51.5-54.7). The odds of a hemodynamically stable chest pain patient with SpO2 ≥ 94% receiving supplemental oxygen in 2011 were 1.4 times lower compared to patients in 2010 (95% CI 1.3-1.6). Similarly, the odds of patients in 2012 receiving supplemental oxygen were 2.3 times lower compared to patients in 2010 (95% CI 2.0-2.6). The odds of receiving supplemental oxygen decreased by 4% for each 1% increase in SpO2 beyond the 94% threshold (OR = 0.96; 95% CI 0.94-0.98). CONCLUSIONS: The prehospital administration of supplemental O2 decreased significantly following release of the 2010 updated guidelines; however, our data revealed that 50% of patients not meeting criteria for administration still received supplemental O2.
