Esophageal Stent Migration Diagnosed With Point-of-Care Ultrasound.

This unique case depicts the first published report of a physician using point-of-care ultrasound to diagnose an esophageal stent migration. Discussed in this article are the sonographic findings that clinicians should be familiar with when evaluating patients with abdominal pain or chest pain who have a history of an esophageal stent. When coupled with a high index of suspicion, ultrasound can be one of the most portable, readily available, low-cost, and minimally invasive techniques for making a rapid diagnosis of esophageal stent migration.

Impact of the utilization of 500 mL IV bags on crystalloid resuscitation volumes administered to trauma patients.

INTRODUCTION: Administering large volumes of crystalloids to trauma patients has been shown to exacerbate metabolic complications of hemorrhage including dilutional coagulopathy and worsening acidosis The aim of this study was to evaluate crystalloid administration volumes in trauma patients after replacing 1 L IV containers with 500 mL IV containers in the emergency department trauma resuscitation bay. MATERIALS AND METHODS: This was a single-center, IRB-approved, retrospective cohort evaluation of adult trauma patients conducted at an 864-bed community tertiary referral center located in the southeastern United States. Patterns of crystalloid administration were examined before and after the trauma resuscitation bay began to exclusively stock 500 mL IV containers. The primary outcome was mean total crystalloid volume infused from time of injury to hospital admission. Secondary outcomes included mean total crystalloid volume infused prior to administration of blood products, proportion of patients who received less than 2 L total of crystalloids, time to initiation of blood products, and mortality in both the emergency department and in-hospital. RESULTS: Patient characteristics were largely similar between both groups including age, mechanism of injury, and Injury Severity Score. For the primary outcome, the mean total crystalloid volume infused from time of injury to hospital administration, patients in the 500 mL IV fluid container group were administered 555 mL less crystalloid when compared to the 1 L IV fluid container group, 1048 mL vs 1603 mL (p < 0.01; 95% CI 406 mL - 704 mL), respectively. After conversion to the 500 mL IV container bags, there was a 27.5% increase in the proportion of patients receiving less than 2 L of crystalloid, 90.5% vs 63.0% in the 500 mL IV fluid container and 1 L IV fluid container groups, respectively (p < 0.01). CONCLUSIONS: Due to reduced mortality, expanding literature and guidelines clearly support minimizing IV crystalloid resuscitation. Institutions must now work to minimize use of IV crystalloids to hemorrhaging trauma patients and a simple solution of using smaller IV fluid bags was shown to improve adherence to this practice.

Inadvertent Methylergonovine administration to a newborn.

Previous case reports describe the inadvertent administration of methylergonovine to newborns resulting in rare, life-threatening events including neonatal death. To our knowledge, no case reports exist detailing inadvertent methylergonovine administration in the emergency medicine literature. A newborn infant presented to the emergency department (ED) at hour five of life following methylergonovine administration with periods of apnea and cyanosis. The infant required intubation, mechanical ventilation, and a seven day neonatal intensive care stay. This rare case describes the potential for this error to occur in the community and heightens the vigilance of emergency medicine providers when caring for newborns in their first hours of life.

Association of emergency department albuterol dispensing with pediatric asthma revisits and readmissions.

INTRODUCTION: Although pediatric asthma continues to be a highly studied disease, data to suggest clear strategies to decrease asthma related revisits or readmissions is lacking. The purpose of our study was to assess the effect of emergency department (ED) direct dispensing of beta-agonist metered dose inhalers on pediatric asthma ED revisit and readmission rates. METHODS: We conducted a retrospective cohort study of pediatric patients discharged from the pediatric ED with a diagnosis of asthma. Our primary outcome measured the rate of asthma revisits to the ED or admissions to the hospital within 28 days. Logistic regression analysis was used to assess ED beta-agonist MDI dispensing and revisit and/or readmission as the outcome. RESULTS: A total of 853 patients met eligibility for inclusion in the study, with 657 enrolled in the Baseline group and 196 enrolled in the ED-MDI group. The Baseline group experienced a revisit and readmission rate of 7.0% (46/657) versus 2.6% (5/196) in the ED-MDI group, (p = 0.026). ED direct dispensing of MDIs was found to be independently associated with a decreased risk of revisit or readmission (odds ratio 0.37; 95% confidence interval 0.14-0.95). CONCLUSIONS: In our study, ED direct dispensing of beta-agonist MDIs resulted in a reduction in 28-day revisit and readmission to the hospital. Further studies should be performed to evaluate the economic impact of reducing these revisits and readmissions against the costs of maintaining a dispensing program. Our findings may support modification of asthma programs to include dispensing MDIs from the emergency department.

Impact of a Hospitalwide Quality Improvement Initiative on Emergency Department Throughput and Crowding Measures.

BACKGROUND: This pre- and postintervention analysis evaluates the impact of a systemwide, comprehensive, executively supported quality improvement (QI) project on emergency department (ED) throughput measures and crowding in a large nonacademic community hospital. METHODS: The two primary endpoints used to assess the impact of the project were (1) the percentage of all patients who were door-in to door-out in less than three hours and (2) the percentage of patients who left without being seen (LWBS). Secondary endpoints for throughput were mean door-in to door-out, door-in to physician, physician to disposition, and disposition to door-out times for all patients. Secondary endpoints for crowding were median disposition to door-out time of admitted patients and the percentage of admitted patients with a disposition to door-out time of ≥ one, two, and six hours. RESULTS: A total of 666,640 patient visits were included in the primary endpoint analyses, with no patients excluded. The percentage of patients meeting the three-hour door-in to door-out goal after the QI project was 81.4%, versus 46.5% in the pre-QI group (difference, 34.9 percentage points; 95% confidence interval [CI] = 34.7-35.1; p < 0.0001). The postintervention LWBS rate was 0.49%, versus 4.00% in the pre-QI group (difference, 3.51 percentage points; 95% CI = 3.43-3.58; p < 0.0001). A total of 417,673 patient visits were screened for inclusion for the secondary endpoint analyses. The pre-QI and post-QI groups were also compared for secondary endpoints, and significant improvement was noted in all analyses. CONCLUSION: This study suggests that a comprehensive systemwide and executively supported QI project can make sustained multiyear improvements in ED throughput and LWBS. Further research is needed to determine if this standardized set of changes can be generalized to other hospital systems.

Time to Blood Pressure Control Before Thrombolytic Therapy in Patients With Acute Ischemic Stroke: Comparison of Labetalol, Nicardipine, and Hydralazine.

BACKGROUND: Elevated blood pressure is common in patients with acute ischemic stroke. Thrombolytic therapy is contraindicated in patients with a systolic blood pressure greater than 185 mmHg or diastolic blood pressure greater than 110 mmHg. Elevated blood pressure can lead to a delay in thrombolytic therapy, which is associated with increased morbidity. There is currently insufficient evidence to support the use of a specific antihypertensive agent in this setting. OBJECTIVE: This study aimed to compare the effects of labetalol, nicardipine, or hydralazine on time to target blood pressure before alteplase administration in patients with acute ischemic stroke. METHODS: A retrospective chart review was conducted to identify patients who received labetalol, nicardipine, or hydralazine to treat elevated blood pressure (systolic blood pressure > 185 or diastolic blood pressure > 110) before intravenous alteplase therapy for ischemic stroke. Data collection included time to blood pressure control, door-to-needle time, total dose administered, and use of additional antihypertensive agent(s). RESULTS: Most patients in this study received labetalol (25/29). Median time to blood pressure control was 10, 22, and 15 minutes in the labetalol, nicardipine, and hydralazine groups, respectively. Among patients who received labetalol, the average time to blood pressure control was 10 minutes longer in those who received 10 mg initially versus those who received 20 mg. Patients who required higher total doses of labetalol tended to achieve blood pressure control more slowly, had longer door-to-needle times, and required additional antihypertensive agents. CONCLUSIONS: Adequate initial dosing of antihypertensive treatment has the potential to reduce time to blood pressure control and possibly time to alteplase therapy. The optimal antihypertensive regimen for controlling blood pressure before alteplase therapy remains unclear.

Pharmacist's impact on acute pain management during trauma resuscitation.

The timely administration of analgesics is crucial to the comprehensive management of trauma patients. When an emergency department (ED) pharmacist participates in trauma resuscitation, the pharmacist acts as a medication resource for trauma team members and facilitates the timely administration of analgesics. This study measured the impact of a pharmacist on time to first analgesic dose administered during trauma resuscitation. All adult (>18 years) patients who presented to this level II trauma center via activation of the trauma response system between January 1, 2009, and May 31, 2013, were screened for eligibility. For inclusion, patients must have received intravenous fentanyl, morphine, or hydromorphone in the trauma bay. The time to medication administration was defined as the elapsed time from ED arrival to administration of first analgesic. There were 1328 trauma response system activations during the study period; of which 340 patients were included. The most common analgesic administered was fentanyl (62% in both groups). When a pharmacist was participating, the mean time to first analgesic administered was decreased (17 vs 21 minutes; P = .03). Among the 78% of patients with documented pain scores, the overall mean reduction in pain scores from ED arrival to ED discharge was similar between the 2 groups. There was a 2.4 point reduction with a pharmacist versus 2.7 without a pharmacist, using a 0 to 10 numeric pain rating scale. The participation of a clinical pharmacist during trauma resuscitation significantly decreased the time to first analgesic administration in trauma patients. The results of this study supplement the literature supporting the integration of clinical ED pharmacists on trauma teams.

The effects of an electronic order set on vancomycin dosing in the ED.

OBJECTIVE: The objective of the study was to assess the impact of a computer physician order entry (CPOE) electronic order set on appropriate vancomycin dosing in the emergency department (ED). METHODS: We conducted a retrospective study examining ED dosing of vancomycin before and after the implementation of an electronic weight-based vancomycin order set. Preimplementation and postimplementation patient records were analyzed between the dates of June 1st and August 31st 2010 for the pre-CPOE group and January 1st to March 31st 2013 for the post-CPOE group. STATISTICAL ANALYSIS: χ(2) analysis, Fisher exact test, and t tests were performed with a 2-sided P value <.05 denoting statistical significance, where appropriate. RESULTS: A total of 597 patients were included in the study, with 220 in the pre-CPOE group and 377 in the post-CPOE group. The use of the electronic order set resulted in a 21.9% increase (P < .05) in appropriate dosing with 67.4% (254/377) of post-CPOE vancomycin doses considered appropriate vs 45.5% (100/220) in the pre-CPOE group. In critically ill patients, there was a 16.3% increase in appropriate dosing with 44.7% (38/85) in the post-CPOE group compared with 28.4% (19/67) in the pre-CPOE group. CONCLUSION: The implementation of an electronic order set increased the percentage of ED patients receiving appropriate initial vancomycin doses. The impact of increasing compliance to vancomycin guidelines is in accordance with stewardship principles that promote optimization of antimicrobial dosing based on individual patient characteristics. More studies are needed to assess the relationship between appropriate vancomycin loading doses in the ED and therapeutic outcomes.

Case report: Pig attack with successful postexposure prophylaxis management.

The domesticated pig or boar is ubiquitous to agriculture around the world and is an important food product in most countries. The males that are able to grow tusks that can approach 5 in are the primary contributor to morbidity and mortality from boar attacks. Literature surrounding domesticated boar attacks is sparse. There are no published cases of domesticated boar attacks that describe successful bacterial postexposure prophylaxis. We present a case report of an attack on an adult female by a domesticated boar.
