AbstractBackgroundThe Focused Assessment with Sonography in Trauma (FAST) exam is a rapid ultrasound test to identify evidence of hemorrhage within the abdomen. Few studies examine the accuracy of paramedic performed FAST examinations. The duration of an ultrasound training program remains controversial. This study's purpose was to assess the accuracy of paramedic FAST exam interpretation following a one hour didactic training session.MethodsThe interpretation of paramedic performed FAST exams was compared to the interpretation of physician performed FAST examinations on a mannequin model containing 300ml of free fluid following a one hour didactic training course. Results were compared using the Chi-square test. Differences in accuracy rate were deemed significant if p < 0.05.ResultsFourteen critical care flight paramedics and four emergency physicians were voluntarily recruited. The critical care paramedics were mostly ultrasound-naive whereas the emergency physicians all had ultrasound training. The correct interpretation of FAST scans was comparable between the two groups with accuracy of 85.6% and 87.5% (∆1.79 95%CI -33.85 to 21.82, p = 0.90) for paramedics and emergency physicians respectively.ConclusionsThis study determined that critical care paramedics were able to use ultrasound to detect free fluid on a simulated mannequin model and interpret the FAST exam with a similar accuracy as experienced emergency physicians following a one hour training course. This suggests the potential use of prehospital ultrasound to aid in the triage and transport decisions of trauma patients while limiting the financial and logistical burden of ultrasound training.

Introduction: The FAST exam – Focused Assessment with Sonography in Trauma - is a rapid test using ultrasound to identify sonographic evidence of hemorrhage within the abdomen. In the prehospital setting, the information from a FAST examination can help triage patients, direct patients to the most appropriate facilities, assist with management strategies and potentially expedite time to definitive intervention. Few studies examine the accuracy of paramedic-only-performed FAST examinations. However, despite the potential benefits to the Canadian prehospital system, a potential barrier to implementation is the tremendous financial and operational burden if paramedics require prolonged ultrasound training courses. In this study, we conducted a double-blinded observational study comparing the accuracy of paramedic-performed FAST versus physician-performed tests on a sonographic Phantom, after a one-hour didactic training session. Methods: The interpretation of paramedic performed FAST exams was compared to the interpretation of physician performed FAST examinations on a mannequin model. The mannequin utilized in this study was a realistic model of a human torso where fluid could be injected into the abdomen to create a realistic ultrasound image of abdominal free fluid. Participants were required to scan the mannequin twice, once with 300 mL of fluid instilled and once with the abdomen free of fluid. Participants were blinded to the status of hemoperitoneum. The primary outcome of the study was accuracy rate of FAST examination by paramedics compared to emergency room physicians. Results were compared using the Chi-square test. Differences in accuracy rate were deemed significant if p < 0.05. Total scan time was reported using means, standard deviations and 95% CIs and was compared between groups using standard t-test. Results: Fourteen critical care flight paramedics and four emergency physicians were voluntarily recruited. The critical care paramedics were ultrasound-naive whereas the emergency physicians had ultrasound training. The correct interpretation of FAST scans was comparable between the two groups 85.6% and 87.5% (Δ1.79 95%CI -33.85 to 21.82, p = 0.90) for paramedics and emergency physicians respectively. Total scan time differed between groups but did not reach statistical significance. Paramedics took longer to complete the FAST examination with a mean (SD) time to complete the two scans of 10.35 (3.43) minutes compared to 7.34 (2.74) minutes for physicians, (Δ3.01 minutes 95%CI -0.97 to 7.00, p = 0.13). Conclusion: This study determined that critical care paramedics were able use ultrasound to detect free fluid on a simulated mannequin model and interpret the FAST exam with a similar accuracy as experienced emergency physicians following a one hour training course. This suggests the potential use of ultrasound in prehospital programs to determine the most appropriate transport destination and aid in the triage of trauma patients while limiting the financial and logistical burden of ultrasound training.

ABSTRACTBackgroundPoint of care ultrasound (POCUS) is an essential tool for physicians to guide treatment decisions in both hospital and prehospital settings. Despite the potential patient care and system utilization benefits of prehospital ultrasound, the financial burden of a “hands-on” training program for large numbers of paramedics remains a barrier to implementation. In this study, we conducted a prospective, observational, double-blinded study comparing paramedics to emergency physicians in their ability to generate usable abdominal ultrasound images after a 1-hour didactic training session.MethodsCanadian aeromedical critical care paramedics were compared against emergency medicine physicians in their ability to generate adequate abdominal ultrasound images on five healthy volunteers. Quality of each scan was evaluated by a trained expert in POCUS who was blinded to the identity of the participant using a 5-point Likert scale and using the standardized QUICk Focused Assessment with Sonography in Trauma (FAST) assessment tool.ResultsFourteen Critical care paramedics and four emergency department (ED) physicians were voluntarily recruited. Of paramedics, 57% had never used ultrasound before, 36% has used ultrasound without formal training, and 7% had previous training. Physicians had a higher proportion of usable scans compared with paramedics (100% v. 61.4%, Δ38.6%; 95% confidence interval, 19.3–50.28).ConclusionsParamedics were not able to produce images of interpretable quality at the same frequency when compared with emergency medicine physicians. However, a 61.4% usable image rate for paramedics following a short 1-hour didactic training session is promising for future studies, which could incorporate a short hands-on tutorial while remaining cost-effective.

AbstractIntroduction:The Advanced Cardiac Life Support (ACLS) guidelines were recently updated to include ultrasound confirmation of endotracheal tube (ETT) location as an adjunctive tool to verify placement. While this method is employed in the emergency department under the guidance of the most recent American College of Emergency Physicians (ACEP; Irving, Texas USA) guidelines, it has yet to gain wide acceptance in the prehospital setting where it has the potential for greater impact. The objective of this study to is determine if training critical care medics using simulation was a feasible and reliable method to learn this skill.Methods:Twenty critical care paramedics with no previous experience with point-of-care ultrasound volunteered for advanced training in prehospital ultrasound. Four ultrasound fellowship trained emergency physicians proctored two three-hour training sessions. Each session included a brief introduction to ultrasound “knobology,” normal sonographic neck and lung anatomy, and how to identify ETT placement within the trachea or esophagus. Immediately following this, the paramedics were tested with five simulated case scenarios using pre-obtained images that demonstrated a correctly placed ETT, an esophageal intubation, a bronchial intubation, and an improperly functioning ETT. Their accuracy, length of time to respond, and comfort with using ultrasound were all assessed.Results:All 20 critical care medics completed the training and testing session. During the five scenarios, 37/40 (92.5%) identified the correct endotracheal placements, 18/20 (90.0%) identified the esophageal intubations, 18/20 (90.0%) identified the bronchial intubation, and 20/20 (100.0%) identified the ETT malfunctions correctly. The average time to diagnosis was 10.6 seconds for proper placement, 15.5 seconds for esophageal, 15.6 seconds for bronchial intubation, and 11.8 seconds for ETT malfunction.Conclusions:The use of ultrasound to confirm ETT placement can be effectively taught to critical care medics using a short, simulation-based training session. Further studies on implementation into patient care scenarios are needed.

As point of care ultrasound (PoCUS) becomes increasingly popular and a standard of care in many clinical settings, the interest for integration in medical undergraduate curriculum is also growing [1]. This project aims to assess whether formal bedside Focused Abdominal Scan for Trauma (FAST) exam training of medical students increases their knowledge and comfort with the use of bedside ultrasound in a family medicine setting at Queen’s University. Third year medical students (n=18) were recruited to participate in a training session involving a 1-hour online video and 2-hour hands-on session. Knowledge based surveys were completed before and after the training. A survey was completed 4 months after the teaching session evaluating knowledge retention, comfort, and application of skills. Student knowledge of PoCUS and FAST increased and was maintained (pre-training 56%±20%, post-training 82%±10%, p<0.001). Self-evaluation of comfort performing a FAST examination (5-point Likert scale) similarly increased post-training session (pre-training 1.4±0.8, post-training 3.8±0.9, p<0.005), but decreased 4 months later (3±1.2, p<0.005). Students in this study were unanimously interested in ultrasound training and the methods used effectively increased theoretical knowledge and comfort with use. Students did not retain their comfort levels with FAST exam 4 months after the training session, nor did they have the opportunity to utilize the skills learned. Further evidence is required to identify the applicability of these results to undergraduate curriculum development.

AbstractTrauma-induced coagulopathy (TIC) is caused by post-traumatic tissue injury and manifests as hypercoagulability that leads to thromboembolism or hypocoagulability that leads to uncontrollable massive hemorrhage. Previous studies on TIC have mainly focused on hemorrhagic coagulopathy caused by the hypocoagulable phenotype of TIC, while recent studies have found that trauma-induced hypercoagulopathy can occur in as many as 22.2–85.1% of trauma patients, in whom it can increase the risk of thrombotic events and mortality by 2- to 4-fold. Therefore, the Chinese People’s Liberation Army Professional Committee of Critical Care Medicine and the Chinese Society of Thrombosis, Hemostasis and Critical Care, Chinese Medicine Education Association jointly formulated this Chinese Expert Consensus comprising 15 recommendations for the definition, pathophysiological mechanism, assessment, prevention, and treatment of trauma-induced hypercoagulopathy.

Background Missed documentation for critical care time (CCT) for dying patients may represent a missed opportunity for physicians to account for intensive care unit (ICU) services, including end-of-life care. We hypothesized that CCT would be poorly documented for dying trauma patients. Methods Adult trauma ICU patients who died between December 2014 and December 2017 were analyzed retrospectively. Critical care time was not calculated for patients with comfort care code status. Critical care time on the day prior to death and day of death was collected. Logistic regression was used to determine factors associated with documented CCT. Results Of 147 patients, 43% had no CCT on day prior to death and 55% had no CCT on day of death. 82% had a family meeting within 1 day of death. Family meetings were independently associated with documented CCT (OR 3.69, P = .008); palliative care consultation was associated with decreased documented CCT (OR .24, P < .001). Conclusions Critical care time is not documented in half of eligible trauma patients who are near death. Conscious (time spent in family meetings and injury acuity) and unconscious factors (anticipated poor outcomes) likely affect documentation.

Abdominal Ultrasonography

Objectives: This prospective study was performed to evaluate the diagnostic accuracy of bedside point-of-care abdominal ultrasonography performed by emergency physician in patients with non-traumatic acute abdominal pain. Methods: The patients, who were admitted to emergency department due to abdominal pain, were included in this study. The emergency physician obtained a routine history, physical examination, blood draws, and ordered diagnostic imaging. After the initial clinical examinations, all the patients underwent ultrasonography for abdominal pathologies by emergency physician and radiologist, respectively. Point-of-care abdominal ultrasonography compared with abdominal ultrasonography performed by radiologist as the gold standard. Results: The study included 122 patients. Gallbladder and appendix pathologies were the most commonly detected in the abdominal ultrasonography. Compared with abdominal ultrasonography, point-of-care abdominal ultrasonography was found to have 89% sensitivity and 94% specificity in gallbladder pathologies; 91% sensitivity and 91% specificity in acute appendicitis; 79% sensitivity and 97% specificity in abdominal free fluid; 83% sensitivity and 96% specificity in ovarian pathologies. Compared to final diagnosis, preliminary diagnoses of emergency physicians were correct in 92 (75.4%) patients. Conclusion: This study showed that emergency physicians were successful in identifying abdominal organ pathologies with point-of-care abdominal ultrasonography after training.
