Femoral Nerve Blocks versus Standard Pain Control for Hip Fractures: A Retrospective Comparative Analysis.

Introduction: Pain control for hip fractures is often achieved via intravenous opioids. However, opioids can have dangerous adverse effects, including respiratory depression and delirium. Peripheral nerve blockade is an alternative option for pain control, which reduces the need for opioid analgesia. The purpose of this study was to compare the use of femoral nerve blocks versus standard pain control for patients with hip fractures. Methods: This retrospective study included adult patients presenting to the emergency department (ED) with isolated hip fractures between April 2021 and September 2022. The intervention group included all patients who received a femoral nerve block during this time. An equivalent number of patients who received standard pain control during that period were randomly selected to represent the control group. The primary outcome was pre-operative opioid requirement, assessed by morphine milligram equivalents (MME). Results: During the study period, 90 patients were identified in each treatment group. Mean pre-operative MME was 10.3 (95% confidence interval [CI]: 7.4-13.2 MME) for the intervention group and 14.0 (95% CI: 10.2-17.8) for the control group (P=0.13). Patients who received a femoral nerve block also had shorter time from ED triage to hospital discharge (7.2 days, 95% CI: 6.2-8.0 days) than patients who received standard care (8.6 days, 95% CI: 7.2-10.0 days). Still, this difference was not statistically significant (P=0.09). Conclusions: Femoral nerve blockade is a safe and effective alternative to opioids for pain control in patients with hip fractures.

Distribution of Lower Extremity Deep Vein Thrombosis and Implications for Limited Compression Ultrasound Examinations.

BACKGROUND: Limited compression bedside ultrasonography (LCUS) including two-point, three-point, and extended compression examinations have become increasingly popular among emergency physicians to assess for lower extremity deep venous thrombosis (DVT). OBJECTIVE: Our objective in this study was to determine the prevalence and distribution of lower extremity DVT in sites identified by complete duplex ultrasonography (CDUS) that may potentially be missed using limited compression ultrasonography techniques. METHODS: This was a retrospective, multicenter study conducted at 12 hospitals within the Northwell Health system over a span of 4 years. Study participants (emergency department patients) underwent CDUS to assess for possible DVT. Images were reviewed and interpreted by radiologists and vascular surgeons at each of the participating institutions. RESULTS: A total of 42,487 CDUS examinations were performed, of which 3383 were positive for DVT. DVTs were deemed to be acute in 2664 (79%) and chronic in the remaining 21% on the basis of comparison with previous studies and appearance of the vein. Of the acute DVTs, 136 (5.1%) were confined to the common femoral vein, 116 (4.4%) to the femoral vein, 8 (0.3%) to deep femoral vein, 213 (8.0%) to popliteal vein, and 934 (35.1) to calf veins alone. CONCLUSIONS: In our study, a significant number of DVTs were identified in sites that may have been potentially missed on LCUS examinations, thereby supporting the use of complete duplex ultrasonography when available.

A Strange Twist.

CASE PRESENTATION: A 16-year-old female presented to the emergency department with acute onset of right lower quadrant abdominal pain for several hours. The patient was afebrile and physical examination was notable for isolated tenderness in the right lower quadrant. Ultrasound and computed tomography demonstrated an adnexal cystic structure. Pelvic magnetic resonance imaging was ordered to better characterize the pathology. DISCUSSION: Isolated fallopian tube torsion is an uncommon entity requiring prompt surgical intervention. Recognition and appropriate management are essential.

Characteristics and Demographics of Patients Requiring Emergent Air Medical.

Background: As integrated health systems become more common, interfacility patient transfers will increase and air transport programs will be prioritized. Understanding characteristics of patients triaged to air medical transport will assist with resource allocation and needs assessment. The objective of this study was to investigate the demographics and clinical characteristics of patients that presented to the emergency department (ED) and subsequently required emergent air medical interfacility transport. Methods: This was a retrospective, multicenter study conducted at eight hospitals within Northwell Health, the largest academic health system in New York state. The study was conducted between December 1, 2014, and July 31, 2020, and included patients who presented to an ED and subsequently required emergent air medical interfacility transport. Results: Overall, the median age was 37 years (IQR 4-66), and 231 (54%) subjects were males. The majority of subjects (59%) had no reported comorbidities, arrived by ambulance (52%), and were emergency severity index triage 2 (48%). Frequent indications for transfer were nontraumatic neurologic (37%), pulmonary or respiratory (13%), trauma (12%), and cardiovascular (12%). Most patients were not ventilated before transport (71%). The median time to call for transport at the sending institution was 2:42 hours (IQR 1:14-6:54), and the median length of stay was 4:12 (IQR 2:31-8:48). Most patients were subsequently admitted (96%) at the receiving institution to an intensive care unit (72%). Conclusions: This study describes patients' demographic and clinical characteristics who required emergent air medical transport. Helicopter transport is costly, and data from these patients may further help our understanding of who is transported by air and how important air transport is to the health system.

The Effect of an Iodinated Contrast Material Shortage on Ordering Patterns in the Emergency Department.

Introduction Iodinated contrast media (ICM) is essential to emergency department care in differentiating and delineating life-threatening pathologies. In May 2022, due to the COVID-19 outbreak, there was an unprecedented disruption in the manufacturing of iodinated contrast. The primary goal of this study was to describe the effects of an ICM shortage on the ordering patterns of emergency medicine physicians. Methods This was a retrospective, observational study with a pre-/post-test design. The study included two 28-day periods. All subjects who underwent a CT were included in the study. The subgroup of patients who underwent a repeat CT with ICM contrast within 1-24 hours was identified. Results During the pre- and post-implementation study periods, 4,574 and 3,973 CT studies were performed. The median length of stay (p=0.013) and time to first CT (p<0.001) both decreased during the post-implementation period. During the post-implementation period, more non-contrast CTs were ordered (p<0.001). During the post-implementation period, there was an increase in non-contrast studies followed by a repeat study with contrast (p=0.003). Conclusions A global ICM shortage resulted in a shift in the ordering patterns of Emergency Medicine (EM) physicians. More non-contrast CT scans were ordered. However, there was also an increase in repeat imaging with ICM material.

An analysis of social determinants of health and structural competency training in global emergency medicine fellowship programs in the United States.

BACKGROUND: Clinicians must be aware of the structural forces that affect their patients to appropriately address their unique health care needs. This study aimed to assess the participation of global emergency medicine (GEM) fellowship programs in formal social determinants of health (SDH) and structural competency (SC) training to evaluate the existence and procedures of such programs. METHODS: A cross-sectional study conducted with a short, online survey with questions regarding the presence of curriculum focused on SDH, SC, educational metrics, and the desire for further formal training in this domain was sent to all 25 GEM fellowship directors through the Global Emergency Medicine Fellowship Consortium (GEMFC) email listserv. RESULTS: Eighty percent (20/25) of GEM fellowship directors responded to the survey. All (20/20) of participating fellowship programs included SDH and SC training in their didactic curriculum, and eight of 20 (40%) programs offered similar training for faculty. Additionally, 19 of 20 (95%) of respondents indicated interest in an open-source tool for emergency medicine (EM) fellowship training in SDH and SC. CONCLUSIONS: While multiple GEM programs offer formal training on SDH and SC, gaps exist regarding similar training for faculty. Additionally, there is a lack of metrics to determine fellows' comfort with the content of this training. As a majority of GEMFC programs requested, an open-source tool would allow a uniform curriculum and measurement of EM fellowship training in SDH and SC.

A Case Report of Delayed Presentation of a Carotid-Jugular Fistula Caused by Blunt Injury from an Arrow.

BACKGROUND: Acquired arteriovenous fistulas (AVFs) are most commonly caused by direct arterial trauma, with 90% of traumatic AVFs due to penetrating trauma. Post-traumatic common carotid artery-internal jugular vein fistulae are rare, with an incidence of 4% to 7% of all traumatic AVFs. CASE REPORT: We present a case of delayed presentation of a patient with shortness of breath, neck pain, and worsening right upper extremity paresthesias 10 days after a blunt injury to the neck by an arrow. He was subsequently found to have a common carotid artery-internal jugular vein fistula and a common carotid pseudoaneurysm on computed tomography angiography. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Post-traumatic common carotid-jugular AVFs are uncommon, especially in patients with delayed presentations and a blunt injury mechanism. If left untreated, AVFs may progress to high-output cardiac failure, atrial fibrillation, and embolization. Clinicians must be aware of this finding, given the potential for significant morbidity.

Frequency of Urinary Tract Infections, Gonorrhea, and Chlamydia in Emergency Department Patients With Acute Scrotal Pain.

BACKGROUND: Acute scrotal pain has many causes. According to the American Urological Association recommendations: history, physical examination, and ultrasound are key in diagnosing acute scrotal pain. OBJECTIVE: The primary objective of this study was to evaluate the frequency of urinary tract infections (UTI) on routine Urinalysis (UA) in patients presenting with acute scrotal pain to the emergency department (ED). METHODS: We conducted a multicentered retrospective chart review of patients who presented to the ED with acute scrotal pain. Patient visits from February 1, 2018 to November 1, 2019 from 13 EDs were analyzed. Demographic data, UA interpretation, urine culture, gonorrhea and chlamydia (GC) testing, clinical findings, treatment outcomes, and ultrasounds were recorded. Patients who did not have a UA and scrotal ultrasound performed or who had a diagnosis of scrotal cellulitis or soft tissue infection were excluded. RESULTS: There were 2,392 patients included in the study. A UTI was present in 173 (7.2%) patients. Of the patients who were found to have a UTI, 100/173 (57.8%) had a concomitant ultrasound diagnosis of epididymitis/orchitis. Also, 731 patients underwent GC testing in addition to standard UA collection, and ultrasound, seven were positive for gonorrhea (0.95%), and 30 were positive for chlamydia (4.10%). CONCLUSIONS: Routine UA collection of patients presenting to the ED with acute scrotal pain should be considered, especially in patients with a concomitant ultrasound diagnosis of epididymo-orchitis. GC testing has limited yield without symptoms suggestive of sexually transmitted infections and a normal ultrasound.
