Emergency Medicine Clinician Experiences Addressing Uncertainty in First-Trimester Bleeding.

The purpose of this work is to understand Emergency Department (ED) clinicians' experiences in communicating uncertainty about first-trimester bleeding (FTB) and their need for training on this topic. This cross-sectional study surveyed a national sample of attending physicians and advanced practice providers (APPs). The survey included quantitative and qualitative questions about communicating with patients presenting with FTB. These questions assessed clinicians' frequency encountering challenges, comfort, training, prior experience, and interest in training on the topic. Of 402 respondents, 54% reported that they encountered challenges at least sometimes when discussing FTB with patients where the pregnancy outcome is uncertain. While the majority (84%) were at least somewhat prepared for these conversations from their training, which commonly addressed the diagnostic approach to this scenario, 39% strongly or moderately agreed that they could benefit from training on the topic. Because the majority of ED clinicians identified at least sometimes encountering challenges communicating with pregnant patients about FTB, our study indicates a need exists for more training in this skill.

Prehospital Use of Whole Blood for Ill and Injured Patients During Critical Care Transport.

OBJECTIVE: Hemodynamic instability and hemorrhagic shock are frequently encountered by emergency medical services providers managing ill and injured patients during critical care transport. Although many critical care transport services commonly transfuse crystalloids and/or packed red blood cells (PRBCs), the administration of whole blood (WB) in prehospital care is currently limited. WB contains PRBCs, plasma, and platelets in a physiologic ratio to aid in oxygen delivery to tissue as well as hemostasis. This study describes a single critical care transport program's experience using WB for critically ill and injured patients and reports important clinical and safety outcomes. METHODS: This study was a retrospective review of patients who were transported by a single rotor wing-based critical care transport service to 1 of 2 tertiary care receiving hospitals within a single health system. Patients who were transported between November 1, 2018, and November 30, 2019, and who received at least 1 unit of low-titer group O WB during critical care transport were included. The primary outcomes of interest included 24-hour mortality and the total 24-hour transfusion requirement. The safety outcomes included transfusion reactions, acute lung injury, acute kidney injury, and the incidence of venous thromboembolism. RESULTS: During the study period, there were 3,084 total patients transported by our critical care transport service. There were 71 patients who received prehospital WB, 64 of whom met the inclusion criteria. The top 3 indications for WB administration included blunt trauma (n = 27, 42.2%), gastrointestinal hemorrhage (n = 15, 23.4%), and penetrating trauma (n = 11, 17.2%). The median total number of blood components transfused within 24 hours was 4.0 (interquartile range, 2.0-9.5), and the overall 24-hour mortality rate was 21.9%. CONCLUSIONS: The administration of WB by emergency medical services providers to critically ill and injured patients in the prehospital setting is feasible and is associated with low incidences of adverse events and transfusion reactions. Further research is needed to elucidate the benefits of WB relative to current prehospital standards of care.

Atypical teratoid rhabdoid tumor in the cerebellum of a 7-year-old boy presenting with headache after a fall.

A 7-year-old boy presented to a community emergency department (ED) after sustaining a minor fall. Although he was found to have a normal neurologic examination, additional history revealed the patient had been having mild intermittent headaches and dizziness in the months preceding the fall. The emergency clinicians ordered neuroimaging, which demonstrated a right cerebellar mass, ultimately diagnosed as atypical rhabdoid/teratoid tumor. Atypical rhabdoid/teratoid tumor is a rare, aggressive brain tumor with a poor prognosis. The objectives of this case report are to emphasize the importance of detailed history with pediatric head trauma, in particular on reassessment, and to discuss briefly the epidemiology and management of atypical teratoid rhabdoid tumor.

Interfacility Transport of the Pregnant Patient: A 5-year Retrospective Review of a Single Critical Care Transport Program.

INTRODUCTION: Interfacility transport of the pregnant patient poses a challenge for prehospital providers as it is an infrequent but potentially high acuity encounter. Knowledge of clinically significant events (CSEs) that occur during these transports is important both to optimize patient safety and also to help enhance crew training and preparedness. This study evaluated a critical care transport program's 5-year longitudinal experience transporting pregnant patients by ground and air, and described CSEs that occurred during the out-of-hospital phase of care. METHODS: This study was a retrospective review of pregnant patients transported by a single critical care transport system into and within a large academic healthcare system. Patients who were pregnant, and were transported from a referring facility to one of the 2 receiving centers within Johns Hopkins Health System between January 1, 2012 and December 31, 2016 were included in this study. The primary outcome of interest was the occurrence of a predefined clinically significant event (CSE) during transport, while a secondary outcome of interest was the indication for transfer. RESULTS: During the study period 1,223 pregnant patients were transported by our critical care transport service. There were 1,101 patients who met inclusion criteria; 693 (62.9%) of whom were transported by ground and 408 (37.1%) who were transported by rotor wing aircraft. The top 3 indications for transfer comprised 71.4% of all patients and included; preterm labor, hypertensive disorder of pregnancy, and other maternal life threatening disorder. The most common events that occurred across all transports were: exacerbation of hypertensive disease requiring intervention (4.5%), hypotension (1.3%), and altered mental status (0.2%). CONCLUSIONS: Incidence of CSEs during the interfacility transport of pregnant patients within our critical care transport system is low (6.0%). Knowledge of the clinically significant events that occur during EMS transport is a vital component of ensuring system quality and optimizing patient safety. This data can be used to augment and focus provider education and training to mitigate and optimize response to future events.

Challenges Related to the Implementation of an EMS-Administered, Large Vessel Occlusion Stroke Score.

INTRODUCTION: There is considerable interest in triaging victims of large vessel occlusion (LVO) strokes to comprehensive stroke centers. Timely access to interventional therapy has been linked to improved stroke outcomes. Accurate triage depends upon the use of a validated screening tool in addition to several emergency medical system (EMS)-specific factors. This study examines the integration of a modified Rapid Arterial oCcclusion Evaluation (mRACE) score into an existing stroke treatment protocol. METHODS: We performed a retrospective review of EMS and hospital charts of patients transported to a single comprehensive stroke center. Adult patients with an EMS provider impression of "stroke/TIA," "CVA," or "neurological problem" were included for analysis. EMS protocols mandated the use of the Cincinnati Prehospital Stroke Score (CPSS). The novel protocol authorized the use of the mRACE score to identify candidates for triage directly to the comprehensive stroke center. We calculated specificity and sensitivity for various stroke screens (CPSS and a mRACE exam) for the detection of LVO stroke. The score's metrics were evaluated as a surrogate marker for a successful EMS triage protocol. RESULTS: We included 312 prehospital charts in the final analysis. The CPSS score exhibited reliable sensitivity at 85%. Specificity of CPSS for an LVO was calculated at 73%. For an mRACE score of five or greater, the sensitivity was 25%. Specificity for mRACE was calculated at 75%. The positive predictive value of the mRACE score for an LVO was estimated at 12.50%. CONCLUSION: In this retrospective study of patients triaged to a single comprehensive stroke center, the addition of an LVO-specific screening tool failed to improve accuracy. Reliable triage of LVO strokes in the prehospital setting is a challenging task. In addition to statistical performance of a particular stroke score, a successful EMS protocol should consider system-based factors such as provider education and training. Study limitations can inform future iterations of LVO triage protocols.

A 15-Year-Old Male With Wide Complex Tachyarrhythmia.

A 15-year-old male presented with exertional syncope and was found to be in an unstable regular wide complex tachyarrhythmia (WCT). After a trial of antiarrhythmic medication, his clinical condition declined, necessitating synchronized cardioversion. Although he noted symptomatic improvement after cardioversion, he was found to be in third-degree heart block. The patient was transported by rotor wing aircraft to a pediatric cardiac intensive care unit where he was ultimately diagnosed with Lyme disease. He was treated with a course of intravenous antibiotics, his heart block resolved, and he was discharged home with a good neurologic outcome.
