Assessment of Paramedic Performance on Difficult Airway Simulation

Drive-thru continuing education to meet learners' needs

BACKGROUND

Continuing education is a requirement for emergency medical services practitioners in Ohio, and simulation-based learning has been effective for this purpose. Limitations to providing simulation for emergency medical services practitioners include a lack of simulation resources or equipment and a lack of trained simulationists to adequately use existing equipment, such as high-fidelity manikins. Here, we sought to provide simulation-based learning in the ambulance bays of our local hospitals to meet these needs.

METHODS

The OhioHealth simulation team, in conjunction with OhioHealth Emergency Medical Services, conducted simulation-based education sessions in ambulance bays scheduled in 2-h blocks for 3 consecutive days at 3 different hospitals in Columbus, Ohio. The outcomes of the education sessions were evaluated based on the ability to meet the educational objectives and the suitability of the environment for learning. In total, 171 learners completed educational sessions and evaluations.

RESULTS

Modified Likert scale surveys were completed by learners to assess their confidence in the learning objectives. For each session, the learners were able to meet the determined learning objectives after the education. Regarding the feasibility of using ambulance bays for education, 90% of learners (155/171) responded that they "Agree" or "Strongly Agree" that the environment was conducive to learning.

CONCLUSION

Using care site ambulance bays with simulation staff and content experts, we were able to effectively deliver simulation-based education. Based on learner perception and ability for education to meet its determined objectives, the ambulance bay provides a feasible way to address existing barriers (cost, access to equipment, and trained staff) to simulation-based education for emergency medical services practitioners.

Does the Location of Endotracheal Intubation Affect the Success of Airway Management in a Helicopter Air Ambulance Service? A Simulation Study

OBJECTIVE

Airway management is a cornerstone of helicopter air ambulance patient management. The purpose of this study was to evaluate the overall quality of airway management of critical care crews in 3 common locations for intubation.

METHODS

This was a prospective observational simulation study assessing the overall airway management of critical care providers managing simulated patients in an emergency department, helicopter, and ambulance. Composite scores were obtained and compared with respect to physical environment and provider certification level.

RESULTS

Fifty-four participants completed the simulations. The median score for the emergency department was 100; for ambulance, it was 80; and for helicopter, it was 80. Ambulance scores were significantly lower than emergency department scores (median difference = -5 points, P = .002) as were helicopter scores (median difference = -10 points, P < .001). The small sample size limited the statistical power to detect differences in provider type, and no statistically significant differences were found in these groups.

CONCLUSION

In this study, the physical location of airway management negatively impacted the overall airway management success as determined by a standardized composite score. This suggests that airway management may have the highest rate of success in an emergency department as opposed to ground ambulance or helicopter air ambulance settings.

Pre-intubation ventilation device for bearded patients: prospective, randomized, crossover trial in anesthetized patients

Having a beard is an independent predictor of difficult ventilation by face mask. This study evaluates the efficacy of a novel intra-oral Bag-Valve-Guedel Adaptor (BVGA) in anaesthetized bearded patients. Patients with ASA score 1-2, scheduled for elective surgery, were recruited for this prospective, crossover trial. Beard length was categorized as < 0.5 cm, 0.5-1 cm, 1-5 cm, or > 5 cm. Patients were ventilated by attending anesthesiologists using the BVGA and a facemask (both with a Guedel oral airway). End-tidal CO₂ (EtCO₂) and expiratory tidal volume (TV) were recorded as was the number of hands required for the procedure. The primary outcome was the difference between BVGA and Facemask. Sixty-one patients were enrolled. Of these, 38 had beards, and 23 were without beards or with beards < 0.5 cm length. In bearded patients, ventilation with the BVGA was superior to the face mask by EtCO₂ and non-inferior by TV (BVGA-vs-Mask, mean [95% CI]: EtCO₂ [mmHg], 33.0 [31.6, 34.3]-vs-27.2 [25.5, 28.8], p < 0.001; TV [ml∙kg^-1 IBW], 8.1 [7.4, 8.9]-vs-6.9 [6.0, 7.7], p = 0.11). The BVGA was found to be superior to the face mask by EtCO₂ across all beard lengths (p ≤ 0.001), but by TV only for the longest beard group (p = 0.009). After securing the BVGA, ventilation was possible without hands in 74% of the cases - clearly impossible with the facemask (p ≤ 0.001). The BVGA is more effective and more convenient than the facemask in anaesthetized bearded patients. A follow-up study is underway to test whether replacing the face mask with the BVGA will improve effectiveness and ease of pre-intubation field ventilation by less-experienced, first responders.

Prehospital Airway Management Training and Education: An NAEMSP Position Statement and Resource Document

AbstractAirway management competency extends beyond technical skills to encompass a comprehensive approach to optimize patient outcomes. Initial and continuing education for airway management must therefore extend beyond a narrow focus on psychomotor skills and task completion to include appreciation of underlying pathophysiology, clinical judgment, and higher-order decision making. NAEMSP recommends:Active engagement in deliberate practice should be the guiding approach for developing and maintaining competence in airway management.EMS learners and clinicians must be educated in an escalating approach to airway management, where basic airway maneuvers form the central focus.Educational activities should extend beyond fundamental knowledge to focus on the development of clinical judgment.Optimization of patient outcomes should be valued over performance of individual airway management skills.Credentialing and continuing education activities in airway management are essential to advance clinicians beyond entry-level competency.Initial and continuing education programs should be responsive to advances in the evidence base and maintain adaptability to re-assess content and expected outcomes on a continual basis.

Performance Standards of Comprehensive Airway Management for Emergency Medicine Residents

BACKGROUND

The Emergency Medicine (EM) Milestone Project provides guidance for assessment of resident trainee airway management proficiency (PC10). Although milestones provide a general structure for assessment, they do not define performance standards. The objective of this project was to establish comprehensive airway management performance standards for EM trainees at both novice and mastery levels of proficiency.

METHODS

Comprehensive airway management standards were derived using standard-setting procedures. A panel of residency education and airway management experts was convened to determine how trainees would be expected to perform on 51 individual tasks in a standardized airway management simulation encompassing preparation, endotracheal intubation, backup airway use, and ventilation. Experts participated in facilitated exercises in which they were asked to 1) define which items were critical for patient safety, 2) predict the performance of a "novice" learner, and 3) predict the performance of a "mastery" learner nearing independent practice. Experts were given a worksheet to complete and descriptive statistics were calculated using STATA 14.

RESULTS

Experts identified 39 of 51 (76%) airway management items as critical for patient safety. Experts also noted that novice trainees do not need to complete all the items deemed to be critical prior to starting practice since they will be supervised by a board-certified EM physician. In contrast, mastery-level trainees would be expected to successfully complete not only the critical tasks, but also nearly all the items in the assessment (49/51, 96%) since they are nearing independent practice.

CONCLUSION

In this study, we established EM resident performance standards for comprehensive airway management during a simulation scenario. Future work will focus on validating these performance standards in current resident trainees as they move from simulation to actual patient care.

Disparities in Feedback Provision to Emergency Medical Services Professionals

INTRODUCTION

Feedback to EMS professionals is a critical component for optimizing patient care and outcomes in the prehospital setting. There is a paucity of data concerning the feedback received by prehospital providers.

OBJECTIVES

The objective of this study was to describe the prevalence of feedback received by EMS professionals in the past 30 days including the types, sources, modes, and utility of feedback. The secondary objective was to identify factors associated with receiving any feedback and, specifically, feedback regarding medical care provided.

METHODS

This was a cross-sectional survey examining currently practicing nationally certified EMS patient care providers (EMT or higher) in non-military and non-tribal settings. Data were collected on provider characteristics along with feedback received. Descriptive statistics were calculated, and multivariable logistic regression models were constructed to assess the relationship between EMS provider characteristics and receiving feedback. A non-respondent survey was administered to assess for non-response bias.

RESULTS

Responses from 32,314 EMS providers were received (response rate = 10.4%) with 15,766 meeting inclusion criteria. In the 30 days preceding the survey, 69.4% (n = 10,924) of respondents received at least one type of feedback with 54.7% (n = 8,592) reporting receiving medical care feedback. Multivariable logistic regression modeling indicated that higher certification level, fewer years of experience in EMS, working for a hospital-based agency, air medical service, and higher weekly call volumes were significantly associated with increased odds of having received at least one type of feedback, and specifically medical care feedback. Additionally, providing primarily medical/convalescent transport and more years of EMS experience were significantly associated with decreased odds of receiving feedback.

CONCLUSION

Feedback to EMS providers is critical to improving prehospital care. In this study, nearly a third of providers did not receive any feedback in a 30-day period, and nearly half reported not receiving medical care feedback. Disparities in the frequency of feedback exist between different provider levels and service settings, while reported feedback decreased with years of experience in the profession. Future work is needed to assess the content of feedback and role in improving patient care and safety.
