Peer recovery coaches and emergency department utilization in patients with substance use disorders.

BACKGROUND: Although Emergency Departments (ED) frequently provide care for patients with substance use disorders (SUD), there are many barriers to connecting them with appropriate long-term treatment. One approach to subside risk in this population is the Peer Recovery Coach (PRC). PRCs are individuals with a lived experience of the rehabilitation process and are a powerful resource to bridge this gap in care by engaging patients and their families and providing system navigation, self-empowerment for behavior change, and harm reduction strategies. The purpose of this project is to describe an ED-based PRC program, evaluating its feasibility and efficacy. METHODS: This was a retrospective quality improvement project conducted at 3 suburban hospitals. All patients arriving to the ED were screened with a brief questionnaire in triage and patients identified as a high-risk had referral placed to a PRC if the patient consented. The PRC met with the patient at the ED bedside if possible. The PRC program members collected prospective data on patient engagement with the PRC at 30, 60, and 90 days post ED encounter. Using the EMR we identified the number of subsequent ED visits at 30, 60, and 90 days (for both medical and substance use disorder-related visits) from the index PRC visit. RESULTS: There were 448 individuals identified and included in this analysis between January 1, 2019 and June 30, 2020, of which 292 (66%) were male and the mean age was 44 (range 18-80). Most patients identified alcohol as the primary substance they used (289, 65%), followed by heroin/opiates (20%). At 30, 60, and 90 days, there were 110 (25%), 79 (18%), and 71 (16%) patients who were still actively engaged in the program, respectively. Among all patients in the cohort, there was essentially no decrease in mean visits before versus after the PRC engagement visit. However, among patients who had at least one prior ED visit, there were significant differences in mean visits across all visit-types: for patients with 1 prior ED visit, 90 day mean decrease in visits = 1.0 visits (95% CI 0.7-1.2), for patients with 5+ prior ED visits, 90 day mean decrease in visits = 3.6 visits (95% CI 2.4-4.8). CONCLUSION: We describe the implementation of an ED-based PRC program for patients with substance use disorders. While we demonstrated that it is feasible for the PRC to engage the patient while in the ED, there was poor follow-up with the program outpatient. For patients with at least one previous SUD visit to the ED, there was a statistically significant reduction in ED utilization after engaging with a PRC while in the ED, suggesting this may be a population that could be targeted to link patients to long term care and decrease repeated ED utilization.

Measuring Emergency Department Staff Perceptions of Causes and Management of Violence.

BACKGROUND: Half of all reported violent incidents in health care settings occur in the emergency department (ED) placing all staff members at risk. However, research typically does not include all ED work groups or validated measures beyond nurses and physicians. OBJECTIVE: The aims of this study were to (a) validate an established instrument measuring perceptions of causes of violence and attitudes toward managing violence within an inclusive workforce sample; and (b) explore variation in perceptions, attitudes, and incidence of violence and safety to inform a violence prevention program. METHODS: This is an investigator-initiated single-site cross-sectional survey design assessing the psychometric properties of the Management of Aggression and Violence Attitude Scale (MAVAS) within a convenience sample (n = 134). Construct validity was assessed using exploratory factor analysis and reliability was evaluated by the Cronbach's α estimation. Descriptive, correlational, and inferential estimates explored differences in perceptions, attitudes, and incidence of violence and safety. RESULTS: Exploratory factor analysis indicated validity of the MAVAS with a seven-factor model. Its internal consistency was satisfactory overall (Cronbach's α= 0.87) and across all subscales (Cronbach's α values = 0.52-0.80). Significant variation in incidence of physical assault, perceptions of safety, and causes of violence was found between work groups. CONCLUSIONS: The MAVAS is a valid and reliable tool to measure ED staff members' perceptions of causes of violence and attitudes toward managing violence. In addition, it can inform training according to differences in work group learner needs.

Posterior Globe Depth for Optic Nerve Sheath Diameter Measurement in Ocular Ultrasound in Healthy Volunteers.

BACKGROUND: Point-of-care ultrasound (POCUS) is a readily available imaging modality in many emergency departments and health care facilities globally. Optic nerve sheath diameter (ONSD) measurement via ocular ultrasound has been shown to accurately predict increased intracranial pressure. Classically, the preferred technique for sonographic measurement of ONSD has specified measurement at an optimal position of 3 mm posterior to the globe. This study aims to validate an alternative approach of depth measurement (between 3 and 8 mm), with the hypothesis that ONSD should not change in size as the distance posterior to the globe increases. METHODS: Healthy volunteers aged > 18 years were studied. A point 3 mm posterior to the optic disc was located. This was repeated at a point 5 mm as well as 8 mm posterior to the globe. RESULTS: We enrolled 10 healthy participants. When evaluating variability in ONSD measurements at each of the three distances, we found that the difference in the measurements at each distance was statistically significant. In investigating pairwise comparisons, there was no difference between 3 and 5 mm, but there were differences in ONSD measurements at 3 and 8 mm, as well as at 5 and 8 mm. CONCLUSION: POCUS is readily available in many emergency departments and health care facilities across the world. The classically preferred technique for sonographic measurement of ONSD has specified measurement at an optimal position of 3 mm posterior to the globe. Our results identified that ONSD can be measured between 3 and 5 mm with no significant changes.

Credentialing Pediatric Emergency Medicine Faculty in Point-of-Care Ultrasound: Expert Guidelines.

ABSTRACT: As point-of-care ultrasound (POCUS) becomes standard practice in pediatric emergency medicine (PEM), it is important to have benchmarks in place for credentialing PEM faculty in POCUS. Faculty must be systematically trained and assessed for competency in order to be credentialed in POCUS and granted privileges by an individual institution. Recommendations on credentialing PEM faculty are needed to ensure appropriate, consistent, and responsible use of this diagnostic and procedural tool. It is our intention that these guidelines will serve as a framework for credentialing faculty in PEM POCUS.

Emergency department sepsis huddles: Achieving excellence for sepsis benchmarks in New York State.

The sepsis order set at our institution was created with the intent to facilitate the prompt initiation of appropriate sepsis care. Once clinical features meeting criteria for systemic inflammatory response syndrome (SIRS) are identified and an infectious source is considered, a "sepsis huddle" is concomitantly initiated. The sepsis huddle was implemented in March of 2016 in order to increase compliance with the sepsis bundles. The sepsis huddle is called via overhead paging system in the emergency department (ED) to notify all staff that there is a patient present who meets SIRS criteria with concern for sepsis requiring immediate attention. The sepsis order set is utilized for these patients and includes laboratory testing, treatment, and monitoring items to meet sepsis "bundle" compliance. In addition, it suggests antibiotic options to be administered based on the presumed source of infection. Each team member responding to a sepsis huddle has a pre-established role outlined to facilitate timely treatment. The Centers for Medicare & Medicaid Services, (CMS), is part of the Department of Health and Human Services (HHS). CMS sepsis guidelines call for periodic patient reassessment, including repeat vital signs, pertinent physical examination findings, and timed lactic acid measurement to determine a patient's response to resuscitation efforts. Our established order set has automated some of these reassessment features to facilitate compliance. Sepsis huddle initiation also triggers a department staff member to track the timing and completion of serial blood draws. Utilizing and adhering to the guidelines of this methodology in the management of these patients has enabled our hospital to improve benchmarking compliance from previously underperforming at the 31st and 49th percentiles in 2015, prior to initiation of the huddle, to a peak compliance at the 81st and 91st percentiles in 2016 and 65th and 83rd percentiles in 2017 for the 3-hour and 6-hour bundles respectively.

Comparative efficiency of exercise stress testing with and without stress-only myocardial perfusion imaging in patients with low-risk chest pain.

OBJECTIVES: To compare major adverse cardiac event (MACE), downstream resource utilization, and direct cost of care for low-risk chest pain patients observed in the clinical decision unit (CDU) with exercise treadmill testing (ETT) and with stress-only myocardial perfusion imaging (sMPI). BACKGROUND: CDUs are poised to increase efficiency and resource utilization. However, the optimal testing strategy that would assure favorable outcomes while decreasing cost is not defined. METHODS: 1016 subjects from 2 locations were propensity score-matched (PSM) by age, gender, pre-test likelihood, Duke treadmill score, and test results. Outcomes were length of stay >24 hours, MACE (acute coronary syndrome, revascularization, cardiac death), downstream resource use (admission for chest pain, repeat testing, angiography), and mean direct cost per patient. RESULTS: PSM yielded 680 patients (340 matches). 98% of all tests were normal. 96.6% of patients were discharged from the CDU within 24 hours but twice as many exceeded 24 hours in the sMPI group. There were no cardiac deaths. MACE rate was 1.47% at 72 hours and 1% at 1 year. Downstream resource use was 4.82% at 72 hours, and 7.69% at 1 year. The sMPI group was event-free longer than the ETT group reflecting less repeat testing. The mean direct cost was 30% higher for sMPI ($3168.70) vs. ETT ($2226.96). CONCLUSION: Low-risk chest pain patients in the observation unit had low MACE rate, not different for ETT vs. sMPI. The majority of ETT and sMPI tests were normal. The sMPI reduced additional testing, but resulted in greater expense and longer stay.

Use of Point-of-Care Ultrasound in the Emergency Department: Insights From the 2012 Medicare National Payment Data Set.

OBJECTIVES: Point-of-care ultrasound is a valuable tool with potential to expedite diagnoses and improve patient outcomes in the emergency department. However, little is known about national patterns of adoption. This study examined nationwide point-of-care ultrasound reimbursement among emergency medicine (EM) practitioners and examined regional and practitioner level variations. METHODS: Data from the 2012 Center for Medicare and Medicaid Services Fee-for-Service Provider Utilization and Payment Data include all practitioners who received more than 10 Medicare Part B fee-for-service reimbursements for any Healthcare Common Procedure Coding System code in 2012. Odds ratios (ORs) and descriptive statistics were calculated to assess relationships between ultrasound reimbursement and practice location, nearby presence of an EM residency, and time elapsed since practitioner graduation. RESULTS: Of 52,928 unique EM practitioners, 391 (0.7%) received limited ultrasound reimbursements for a total of 16,389 scans in 2012. Urban counties had an OR of 5.4 (95% confidence interval, 3.8-7.8) for receiving point-of-care ultrasound reimbursements compared to rural counties. Counties with an EM residency had an OR of 84.7 (95% confidence interval, 42.6-178.8) for reimbursement compared to counties without. The OR for receiving reimbursement was independent of medical school graduation year (P = .83); however, recent graduates performed more scans (P = .02). CONCLUSIONS: A small minority of EM practitioners received reimbursements for point-of-care ultrasound from Medicare beneficiaries. These practitioners were more likely to reside in urban and academic settings. Future efforts should assess the degree to which our findings reflect either low point-of-care ultrasound use or low rates of billing for ultrasound examinations that are performed.

Higher success rates and satisfaction in difficult venous access patients with a guide wire-associated peripheral venous catheter.

STUDY OBJECTIVE: This study compares first pass success rates and patient and physician satisfaction scores of using a guide wire-associated peripheral venous catheter (GAPIV) vs a traditional peripheral venous catheter in difficult to obtain venous access patients. METHODS: A total of 200 patients were enrolled prospectively from a convenience sample in a large urban academic emergency department. Patients were included when they were deemed difficult access per study criteria. Patients were alternated to receiving either a traditional peripheral venous catheter or a GAPIV. The number of attempts, the number of catheters used, and patient and physician satisfaction scores were recorded. RESULTS: A total of 100 patients were enrolled into each group. First attempt success was 85% with GAPIV vs 22% with the traditional peripheral venous catheter (P < .0001). Sixty-two percent of patients required a second stick with the conventional catheter compared to 15% with the GAPIV. The average number of attempts overall for the GAPIV product was 1.2 with an SD of 0.4 attempts vs 1.9 and an SD of 0.6 attempts with the traditional peripheral venous catheter; P < .0001. Using a 5-point Likert scale, the GAPIV had a median patient satisfaction score of 5 at insertion compared with the traditional peripheral venous catheter score of 2; P < .0001. Median physician satisfaction with the GAPIV study device was 5 at time of insertion, compared to 3 for the traditional peripheral venous catheter. CONCLUSION: The GAPIV product demonstrated significantly higher first attempt success and patient satisfaction compared to a traditional peripheral venous catheter in difficult to obtain venous access patients. Physician satisfaction was also favorable due to ease of access, time, and efficiencies gained.

Central Venous Catheterization: Are We Using Ultrasound Guidance?

OBJECTIVES: To assess the self-reported frequency of use of ultrasound guidance for central venous catheterization by emergency medicine (EM) residents, describe residents' perceptions regarding the use of ultrasound guidance, and identify barriers to the use of ultrasound guidance. METHODS: A longitudinal cross-sectional study was conducted at 5 academic institutions. A questionnaire on the use of ultrasound guidance for central venous catheterization was initially administered to EM residents in 2007. The same questionnaire was distributed again in the 5 EM residency programs in 2013. RESULTS: In 2007 and 2013, 147 and 131 residents completed questionnaires, respectively. A significant increase in the use of ultrasound guidance for central venous catheterization was reported in 2013 compared to 2007 (P< .001). In 2007, 53% (95% confidence interval, 44%-61%) of residents reported that they were initially trained in central venous catheterization using ultrasound guidance compared to 96% (95% confidence interval, 92%-99%) in 2013 (P < .0001). In 2007, more residents thought that faculty were insufficiently adopting ultrasound (42% versus 9%), and there was a lack of ultrasound teaching during residency training (14% versus 5%) compared to 2013. CONCLUSIONS: The use of self-reported ultrasound guidance for central venous catheterization significantly increased from 2007 to 2013 at academic institutions. Most residents were aware of the benefits of using ultrasound guidance. Although faculty adoption of ultrasound for central venous catheterization remains a barrier, it has decreased.

Saline Flush Test: Can Bedside Sonography Replace Conventional Radiography for Confirmation of Above-the-Diaphragm Central Venous Catheter Placement?

OBJECTIVES: Resuscitation often requires rapid vascular access via central venous catheters. Chest radiography is the reference standard to confirm central venous catheter placement and exclude complications. However, radiographs are often untimely. The purpose of this study was to determine whether dynamic sonographic visualization of a saline flush in the right side of the heart after central venous catheter placement could serve as a more rapid confirmatory study for above-the-diaphragm catheter placement. METHODS: A consecutive prospective enrollment study was conducted in the emergency departments of 2 major tertiary care centers. Adult patients of the study investigators who required an above-the-diaphragm central venous catheter were enrolled during the study period. Patients had a catheter placed with sonographic guidance. After placement of the catheter, thoracic sonography was performed. The times for visualization of the saline flush in the right ventricle and sonographic exclusion of ipsilateral pneumothorax were recorded. Chest radiography was performed per standard practice. RESULTS: Eighty-one patients were enrolled; 13 were excluded. The mean catheter confirmation time by sonography was 8.80 minutes (95% confidence interval, 7.46-10.14 minutes). The mean catheter confirmation time by chest radiograph availability for viewing was 45.78 minutes (95% confidence interval, 37.03-54.54 minutes). Mean sonographic confirmation occurred 36.98 minutes sooner than radiography (P< .001). No discrepancy existed between sonographic and radiographic confirmation. CONCLUSIONS: Confirmation of central venous catheter placement by dynamic sonographic visualization of a saline flush with exclusion of pneumothorax is an accurate, safe, and more efficient method than confirmation by chest radiography. It allows the central line to be used immediately, expediting patient care.

Technology advancements in the diagnosis and treatment of peritonsillar abscess.

A 17 year-old man presented to the emergency department with signs and symptoms of a peritonsillar abscess. His trismus was sopronounced that it was too difficult to drain the abscess under dynamic ultrasound guidance. It was suggested that localization of the abscess with ultrasound be used concurrently with video laryngoscopy. The ultrasound was used to localize the abscess and visualize its depth. The laryngoscope was then used to visualize the exact spot, where the ultrasound probe characterized the abscess. The probe was then removed, and a needle attached to a syringe was used in its place. Drainage was facilitated using the video laryngoscope in the oral cavity. Seven milliliters of pus was removed, and the patient drastically improved after the procedure.

Do emergency ultrasound fellowship programs impact emergency medicine residents' ultrasound education?

OBJECTIVES: Recent years have seen a rapid proliferation of emergency ultrasound (EUS) programs in the United States. To date, there is no evidence supporting that EUS fellowships enhance residents' ultrasound (US) educational experiences. The purpose of this study was to determine the impact of EUS fellowships on emergency medicine (EM) residents' US education. METHODS: We conducted a cross-sectional study at 9 academic medical centers. A questionnaire on US education and bedside US use was pilot tested and given to EM residents. The primary outcomes included the number of US examinations performed, scope of bedside US applications, barriers to residents' US education, and US use in the emergency department. The secondary outcomes were factors that would impact residents' US education. The outcomes were compared between residency programs with and without EUS fellowships. RESULTS: A total of 244 EM residents participated in this study. Thirty percent (95% confidence interval, 24%-35%) reported they had performed more than 150 scans. Residents in programs with EUS fellowships reported performing more scans than those in programs without fellowships (P = .04). Significant differences were noted in most applications of bedside US between residency programs with and without fellowships (P < .05). There were also significant differences in the barriers to US education between residency programs with and without fellowships (P < .05). CONCLUSIONS: Emergency US fellowship programs had a positive impact on residents' US educational experiences. Emergency medicine residents performed more scans overall and also used bedside US for more advanced applications in programs with EUS fellowships.

General Surgery Residents Improve Efficiency but Not Hospital Length of Stay in Trauma Care.

Background Good Samaritan University Hospital (GSUH) has been preliminary approved to become a Level I Trauma Center. The American College of Surgeons (ACS) requires Level I Trauma Centers to have senior surgery residents on the trauma service. To fulfill this requirement, GSUH has established an affiliation with Stony Brook University Hospital, a tertiary care hospital with an Accreditation Council for Graduate Medical Education-approved five-year postgraduate training program in General Surgery, to have senior surgery residents from their training program rotate and provide care to trauma patients beginning in July of 2021. Numerous studies over the past few decades have shown conflicting results on patient outcomes with resident involvement. A majority of the studies published only evaluated residents who were native to the respective hospitals. Our study evaluated the impact of surgery residents visiting from an outside hospital on hospital length of stay (LOS) in admitted trauma patients. As increased hospital LOS is strongly associated with increased hospital-acquired complications, increased healthcare costs, and poor patient experience, we used this to evaluate the efficiency of our trauma team with the addition of visiting surgery residents. Methodology A retrospective study was conducted utilizing the hospital's trauma registry. Patients were divided into two groups: the first two years before the addition of surgery residents from July 1st, 2019, to June 30th, 2021, and the second two years after the addition of surgery residents from July 1st, 2021, to June 30th, 2023. The primary outcome measured the hospital LOS between the two groups. Pearson's chi-square test was used to analyze all categorical data, and a t-test was used to compare differences in means. Results From July 1st, 2019, to June 30th, 2023, a total of 7,081 patients were admitted to the trauma service: 3,411 in the group with no surgery residents, and 3,670 patients in the group with residents (p = 0.052). The primary outcome, hospital LOS, was not significantly affected by the addition of surgery residents to the trauma service. Hospital LOS before surgery residents was 4.40 days compared to with residents at 4.41 days (p = 0.944). Mortality was significantly decreased with resident involvement at 1.9% compared to no residents at 2.7% (p = 0.017). Interestingly, the Emergency Department LOS was significantly longer in the group with residents, 268.82 minutes vs. 232.19 minutes (p = 0.004). The average New Injury Severity Score was 9.02 in the group with no residents and 9.04 in the group with surgery residents (p = 0.927). The majority of traumas in both groups were blunt trauma 96.5% with no residents vs. 97.1% with residents (p = 0.192). Conclusions The addition of visiting surgery residents to the trauma team did not significantly increase hospital LOS. Ultimately, having visiting residents on the trauma service may enhance resident education without compromising hospital LOS. Training at different hospitals can allow residents to experience different patient populations and different hospital protocols, making them adaptable and more prepared to work in different hospital settings, whether academic or community. Hospitals without their own residency programs could potentially form affiliations with residency programs to meet the ACS requirements, which can bring more patients to their hospitals.

Near-miss in focused lower-extremity ultrasound for deep venous thrombosis.

BACKGROUND: Focused, proximal compression ultrasound (FPCUS) is a commonly used point-of-care study in the Emergency Department (ED). Pelvic vein deep venous thrombosis (DVT) is a rare presentation, and Emergency Physicians need to be aware of the limitations and pitfalls of FPCUS. OBJECTIVE: A case of external iliac vein DVT diagnosed in the ED is presented, with a focus on subtle signs seen during FPCUS that led to the diagnosis and additional ultrasound techniques to aid in appropriate point-of-care diagnosis. CASE REPORT: We describe a patient who presented with lower-extremity pain and was subsequently diagnosed with external iliac DVT. A FPCUS study by Emergency Physicians was performed and demonstrated subtle findings that led to further investigation and appropriate diagnosis. CONCLUSION: Emergency physicians using FPCUS in the evaluation of lower-extremity pain or swelling need to be aware of the pitfalls, limitations, and advanced techniques to avoid misdiagnosis while evaluating for DVT.

Resource Deployment in Response to Trauma Patients.

Background Variance in the deployment of the trauma team to the emergency department (ED) can result in patient treatment delays and excess burden on ED personnel. Characteristics of trauma patients, including mechanism of injury, injury type, and age, have been associated with differences in trauma resource deployment. Therefore, this retrospective, single-site study aimed to examine the deployment patterns of trauma resources, the characteristics of the trauma patients associated with levels of trauma resource deployment, and the deployment impact on ED workforce utilization and non-trauma ED patients. Methodology This was an investigator-initiated, single-institution, retrospective cohort study of all patients designated as a trauma response and admitted to a community hospital's ED from July 01, 2019, through July 01, 2022. Results Resource deployment for trauma patients varied by mechanism of injury (p < 0.001), injury type (p < 0.001), and patient age groups (p < 0.001). Specifically, there was a lower average trauma activation for geriatric trauma patients with a fall as a mechanism of injury compared to all younger patient groups with any mechanism of injury (F(5) = 234.49, p < 0.001). In the subsample, there was an average of 3.35 ED registered nurses (RNs) allocated to each trauma patient. Additionally, the ED RNs were temporarily reallocated from an average of 4.09 non-trauma patients to respond to trauma patients, despite over a third of the trauma patients in the subsample being the trauma patients being discharged home from the ED. Conclusions Trauma activation responses need to be standardized with a specific plan for geriatric fall patients to ensure efficient use of trauma and ED personnel resources.

Infected urachal cyst initially misdiagnosed as an incarcerated umbilical hernia.

BACKGROUND: Urachal abnormalities are a rare cause of lower abdominal pain. They are often initially mistaken for more common causes of lower abdominal pain, and the diagnosis is usually made during evaluation for one of these more common conditions. CASE REPORT: We report a case of a painful periumbilical mass ultimately diagnosed as an infected urachal cyst. Although the cyst was evident sonographically, it was misidentified as an umbilical hernia, and the correct diagnosis was not made until the patient underwent computed tomography of the abdomen and pelvis before surgery. CONCLUSION: Emergency physicians should consider urachal disease in patients presenting with lower abdominal pain and should also be familiar with both the clinical and radiologic findings characteristic of this disease.

Emergency ultrasound in the detection of pediatric long-bone fractures.

BACKGROUND: Long-bone fractures represent one of the most commonly sustained injuries following trauma and account for nearly 4% of emergency department visits in the United States each year. These fractures are associated with a significant risk of bleeding and neurovascular compromise. Delays in their identification and treatment can lead to loss of limb and even death. Although emergency physicians currently rely predominantly on radiography for the examination of long-bone injuries, emergency ultrasound has several advantages over radiography and may be useful in the identification of long-bone fractures. Ultrasound is rapid, noninvasive, and cost-effective. Unlike radiography, ultrasound does not expose children to ionizing radiation, which has been linked to cancer. OBJECTIVE: The goal of this study was to assess the agreement between emergency physicians' and radiologists' final assessments of suspected long-bone fractures using emergency ultrasound and radiography, respectively, in the pediatric population. METHODS: This is a prospective study involving a convenience sample of pediatric patients (<18 years of age) who presented to the emergency department of a university-affiliated, level I trauma center between March 2008 and January 2009 with at least 1 suspected long-bone fracture. Suspected fractures were characterized by swelling, erythema, and localized pain. Patients who had a history of fracture, extremity deformity, orthopedic hardware in the traumatized area, or an open fracture were excluded from this study. Each investigator received limited, focused training in the use of ultrasonography for fracture identification and localization. This training consisted of a brief didactic session and video review of normal and fractured long-bones. RESULTS: A total of 53 subjects (mean age, 10.2 [SD, 3.8] years; 56.6% were male) were enrolled, which corresponded to 98 ultrasound examinations. Sixty-nine scans (70.4%) involved bones of the upper extremity, and 29 (29.6%) the lower extremity. Radiography identified a total of 43 fractures. The sensitivity and specificity of ultrasound in the detection of long-bone fractures were 95.3% (95% confidence interval [CI], 82.9%-99.2%) and 85.5% (95% CI, 72.8%-93.1%), respectively, and the positive and negative predictive values were 83.7% (95% CI, 68.8%-92.2%) and 96% (95% CI, 84.9%-99.3%), respectively. Overall, ultrasound detected 100.0% of diaphyseal fractures and 27 (93.1%) of 29 end-of-bone or near-joint fractures.Radiography revealed 6 displacements that met the published criteria for reduction, all of which were also revealed by ultrasound. The overall sensitivity and specificity for ultrasound identifying the need for reduction were 100.0% (95% CI, 51.7%-100.0%) and 97.3% (95% CI, 84.2%-99.9%), respectively, and positive and negative predictive values were 85.7% (95% CI, 42.0%-99.2%) and 100.0% (95% CI, 88.0%-100.0%), respectively. CONCLUSIONS: Emergency department physician-performed focused ultrasound was more accurate in detecting diaphyseal fractures than in detecting fractures in the metaphysis and/or epiphysis. The high sensitivity and specificity of ultrasound in the detection of long-bone fractures and the need for reduction support the use of ultrasound in the evaluation of suspected long-bone fractures in children.

Cervical ectopic pregnancy diagnosed by point-of-care emergency department ultrasound.

BACKGROUND: Although rare, cervical ectopic pregnancy (EP) represents a potentially lethal variation of a common first-trimester disease entity. CASE REPORT: We report a case of low abdominal pain and vaginal bleeding diagnosed as a cervical EP by point-of-care ultrasound. CONCLUSION: Familiarity with cervical EP and its sonographic appearance is essential for emergency physicians because it can be easily mistaken for an intrauterine pregnancy or other obstetric/gynecologic pathology, such as an incomplete abortion or nabothian cyst. The management of each of these differs substantially, making accurate diagnosis crucial.
