ABSTRACT

OBJECTIVES: Manufacturer recalls and altered supply chains during the coronavirus disease 2019 (COVID-19) pandemic caused a nationwide shortage of blue-top tubes (BTTs). Most non-point-of-care coagulation tests use these tubes, leaving laboratories and health care facilities in short supply. The Department of Pathology and Laboratory Medicine at Cedars-Sinai Medical Center implemented interventions to conserve supply without sacrificing patient safety. METHODS: In a retrospective quality improvement analysis, we examined coagulation testing and BTT utilization over the 3-month interval during which our interventions were applied. Our study assessed the interventions' effectiveness by evaluating changes in BTT utilization, coagulation testing volume, and patient impact. RESULTS: Average daily use (ADU) of BTT before and after the intervention were 476 and 403, respectively-a 15.2% reduction. Notably, the Emergency Department had a reduction in ADU of 43.3%. Average daily volumes of coagulation assays performed decreased from 949 to 783-a 17.5% reduction. No adverse events from the Pharmacy Department were identified during the study period. CONCLUSIONS: Interventions resulting in significant reductions were in divisions with effective management and supervision. Success in navigating the BTT shortage stemmed from timely announcements, action, and effective communication. Our recommendations established more effective coagulation assay utilization, decreased overall BTT use, and prevented patients with coagulopathic disorders from experiencing adverse consequences.

ABSTRACT

STUDY OBJECTIVE: Determine whether an expanded emergency medicine (EM) pharmacist scope of practice reduces the frequency of major delays in subsequent antibiotic administration in patients boarded in the emergency department (ED). METHODS: A pre-post, quasi-experimental study conducted from November 2019-March 2020 at a single-center tertiary academic medical center following the implementation of an expanded EM pharmacist scope of practice. Adult patients were included if they received an initial antibiotic dose in the ED and deemed to be high-risk. Subsequent antibiotic doses were reordered by EM pharmacists for up to 24-h after the initial order pending ED length of stay (LOS). The historical control group consisted of retrospective chart review of cases from the previous year. RESULTS: The study identified that of the 181 participants enrolled, major delays in subsequent antibiotic administration occurred in 13% of the intervention group and 48% of the control group (p < 0.01). When compared to the control group, the intervention group had a significant decrease in the number of delays among antibiotics dosed at 6-h (39% vs 13%) and 8-h (60% vs 8%) intervals. For antibiotics dosed at 12-h intervals, no statistically significant difference was observed between the control and intervention groups respectively (19% vs 5%). A statistically significant lower incidence of in-hospital mortality was observed in the intervention group (3% vs 11%, p = 0.02). In the intervention group, 97% of patients received subsequent antibiotic doses while boarded in the ED, compared to 65% in the control group (<0.01). CONCLUSION: Expanding EM pharmacist scope of practice was associated with a significant reduction in the frequency of major delays in subsequent antibiotic administration as well as a decreased incidence of hospital mortality.

ABSTRACT

BACKGROUND: Interruptions are recognized as potentially harmful to safety and efficiency, and are especially prevalent in the emergency department (ED) setting. Policies urging immediate review of all electrocardiograms (ECGs) may lead to numerous and frequent interruptions. OBJECTIVE: We assessed the role of ECG review as a source of ED interruptions to characterize a potential target for interventions. METHODS: We analyzed emergency physician time use during the course of a clinical shift using a time-and-motion design. A research assistant observed a convenience sample of shifts, observing and logging transitions between different tasks using an electronic device. Instances of ECG review were tallied, with start and ending times of ECG review recorded to the nearest second. An ECG review was considered an interruption if the immediate prior and subsequent tasks were the same. RESULTS: Twenty shifts were observed for a total of 149 h. There were 211 ECG reviews, (mean rate 1.4 per hour), with more frequent review among physicians staffing a zone with higher-acuity patients (2.8 per hour), where clustering of multiple ECG reviews in succession was more common. Seventy-five percent of ECG reviews required < 30 s. Of all 211 ECG reviews, 102 (48%) were an interruption. The tasks most frequently interrupted were electronic medical record system use (68 of 102, 67%) and communicating with ED staff in person (18 of 102, 18%). CONCLUSIONS: Review of ECGs was a substantial driver of interruptions for emergency physicians. Interventions to integrate ECG review more naturally into physician workflow may improve patient safety by reducing these interruptions.

ABSTRACT

BACKGROUND: This study investigates the impact of standing electric scooter-related injuries within an entire integrated hospital system. METHODS: We performed a retrospective review of patients involved in standing electric scooter incidents presenting throughout an urban hospital network over a 10 month period. Rates of Google searches of scooter-related terms performed locally were used as a surrogate for ride frequency. Injury, mechanism, and cost data were analyzed. RESULTS: Data on 248 patients were reviewed. Twenty-three (9%) were under 18 years old. Loss of balance was the most common cause of injury accounting for nearly half, while tripping over a scooter 14 (6%) affected the elderly disproportionately. Eight (3%) riders wore helmets. All TBI and closed head injuries occurred in unhelmeted patients. Most incidents occurred in the street, only one in a bicycle lane. Facilities costs were greater for patients under the influence of alcohol and marijuana. CONCLUSION: Policies related to the use of mandated safety equipment, dedicated bicycle lanes, and the proper storage of empty vehicles should be further investigated.

ABSTRACT

Objective: There is minimal evidence describing outcomes for emergency department (ED) patients with suspected coronavirus disease 2019 (COVID-19) infection who are not hospitalized. The study objective was to assess 30-day outcomes (ED revisit, admission, ICU admission, and death) for low-risk patients discharged after ED evaluation for COVID-19. Methods: This was a retrospective cohort study of patients triaged to a COVID-19 surge area within an urban ED and discharged between March 12 and April 6. Physicians were encouraged to discharge patients if they were well-appearing with few comorbidities. Data were collected from review of medical records and phone follow-up, and the analysis was descriptive. Results: Of 452 patients, the median age was 38, and 61.7% had no comorbidities. Chest radiographs were performed for 50.4% of patients and showed infiltrates in 14% of those tested. Polymerase chain reaction testing was performed for 28.3% of patients during the index ED visit and was positive in 35.9% of those tested. Follow-up was achieved for 75.4% of patients. ED revisits occurred for 13.7% of patients. The inpatient admission rate at 30 days was 4.6%, with 0.7% requiring intensive care. Median number of days between index ED evaluation and return for admission was 5 (interquartile range 3-7, range 1-17). There were no known deaths. Conclusions: A minority of low-risk patients with suspected COVID-19 will require hospitalization after being discharged home from the ED. Outpatient management is likely safe for well-appearing patients with normal vital signs, but patients should be instructed to return for worsening symptoms including labored breathing. Future work is warranted to develop and validate ED disposition guidelines.

ABSTRACT

BACKGROUND: Factor Xa (FXa) inhibitors, used for stroke prevention in atrial fibrillation and venous thromboembolism treatment and prevention, are the dominant non-Vitamin K oral anticoagulants on the market. While major bleeding may be less common with these agents compared to warfarin, it is always a risk, and little has been published on the most serious bleeding scenarios. This study describes a cohort of patients with FXa inhibitor-associated life-threatening bleeding events, their clinical characteristics, interventions and outcomes. METHODS: We performed a retrospective, 5-center review of FXa inhibitor-treated major bleeding patients. Investigators identified potential cases by cross-referencing ICD-9/10 codes for hemorrhage with medication lists. Investigators selected cases they deemed to require immediate reversal of coagulopathy, and reviewed charts for characteristics, reversal strategies and other interventions, and outcomes. RESULTS: A total of 56 charts met the inclusion criteria for the retrospective cohort, including 29 (52%) gastrointestinal bleeds (GIB), 19 (34%) intracranial hemorrhages (ICH) and 8 (14%) others. Twenty-four (43%) patients received various factor or plasma products, and the remainder received supportive care. Thirty-day mortality was 21% (n=12). Re-anticoagulation within 30-days occurred in 23 (41%) patients. Thromboembolic events (TEEs) occurred in 6 (11%) patients. No differences were observed in outcomes by treatment strategy. CONCLUSIONS: This cohort of FXa inhibitor-associated major bleeding scenarios deemed appropriate for acute anticoagulant reversal illustrates the variable approaches in the absence of a specific reversal agent.

ABSTRACT

A 41-year-old woman presented to the emergency department with a chief complaint of hematuria three days status post extracorporeal shockwave lithotripsy. The patient described a three-day history of worsening left-sided abdominal pain immediately following the procedure. She denied any fever, chills, changes in bowel habits, hematochezia, increased urinary frequency, urinary urgency, or dysuria. Physical exam revealed tenderness to palpation in the left upper quadrant, left flank and periumbilical region with mild guarding. Laboratory studies revealed an anemic patient with downward trending hematocrit (red blood cell count of 3.41 10(6)/µL, hemoglobin of 10.6 g/dL, and a hematocrit of 31.3% down from 43% a week and a half prior). Urinalysis revealed red and cloudy urine with 3+ leukocytes. A chest radiograph was unremarkable. A computed tomography of the chest, abdomen, and pelvis showed a laceration to the lateral aspect of the mid left kidney with a hematoma measuring 3.2 cm in thickness (Figure). The patient was subsequently admitted to the hospital for monitoring and discharged on day nine.

ABSTRACT

BACKGROUND: Transfusion medicine is a common practice in the emergency department (ED) and other outpatient settings, and may be complicated by a low rate of potentially fatal transfusion-related reactions. OBJECTIVES: This article presents a case of transfusion-related acute lung injury (TRALI) diagnosed and treated in the ED and reviews the differential diagnosis of acute transfusion reactions. CASE REPORT: A 74-year-old woman presented to the ED from the hospital's transfusion center with fever and respiratory distress immediately after the start of her second unit of red blood cell transfusion. Chest radiograph demonstrated a pattern consistent with acute respiratory distress syndrome (ARDS). After 48 h of respiratory support and antibiotic therapy, the patient's condition improved. CONCLUSION: TRALI is a clinical diagnosis with presentation similar to that of ARDS. Prompt differentiation from other transfusion reactions and initiation of appropriate treatment is crucial in minimizing the morbidity and mortality associated with this syndrome.

ABSTRACT

BACKGROUND: Acute calcific tendinitis, a benign and self-limiting inflammatory condition commonly seen in the shoulder, is also described in many other tendons, including those in the hand and wrist. When involving the wrist, acute calcific tendinitis is often misdiagnosed and mistaken for infection. OBJECTIVE: We present this case to increase familiarity with this condition to avoid errors in diagnosis resulting in inappropriate treatment with antibiotics or even surgery. CASE REPORT: A 27-year-old man presented to the Emergency Department with a 2-week history of volar wrist pain, with sudden increase in pain associated with chills and new onset swelling and redness of the wrist. Plain radiographs showed characteristic soft-tissue calcification overlying the insertion of the flexor carpi ulnaris tendon into the wrist. Treatment with ibuprofen and splinting resulted in complete symptom resolution. CONCLUSION: Acute calcific tendinitis is an important consideration in the differential diagnosis of acute wrist pain. Radiographs are helpful in confirming the diagnosis when symptoms and examination findings are characteristic.

ABSTRACT

BACKGROUND: Acute aortic dissection is a life-threatening disease that is often a diagnostic challenge in the Emergency Department (ED). Patients with acute aortic dissection often have underlying hypertension and atherosclerotic disease, and commonly present with acute-onset severe chest or back pain in their sixth or seventh decades of life. Aortic dissection, however, can also be seen in patients < 40 years old and may present chronically, with symptom duration longer than 2 weeks. OBJECTIVE: We present an unusual case of chronic aortic dissection in a young patient, followed by a review of the literature on chronic aortic dissections and aortic dissections in young patients. CASE REPORT: We report a case of chronic aortic dissection in a 32-year-old man with a history of untreated hypertension who presented to the ED with palpitations and mild shortness of breath. CONCLUSION: Acute and chronic thoracic aortic dissections can occur in patients of all ages, as well as in patients with atypical signs and symptoms.

ABSTRACT

OBJECTIVES: To assess the impact of an emergency department (ED) guideline employing selective use of helical computed tomography (CT) on clinical outcomes of female patients with suspected appendicitis. METHODS: All patients presenting with suspected appendicitis were prospectively enrolled and managed in accordance with a guideline incorporating selective use of helical CT. Although not the objective of this investigation, male patients were included for purposes of comparison. Patients with clinically evident appendicitis were referred to the surgical service, and patients with equivocal presentations were studied with helical CT. Patients were followed to final surgical or clinical outcomes. Outcome measures included time from ED presentation to laparotomy and rate of appendiceal perforation. These measures were compared with those of a historical cohort of patients preceding the use of helical CT. RESULTS: A total of 310 consecutive patients with suspected appendicitis were enrolled; 92 had appendicitis. Sixty patients were referred to the surgical service without helical CT, and 41 had appendicitis (68%). Helical CT was performed on 250 patients; 51 had appendicitis (20%). For males, the mean interval from ED presentation to laparotomy was 559 minutes (95% CI = 444 to 674 minutes) during guideline use and 480 minutes (95% CI = 405 to 555 minutes) before. This interval for females was 433 minutes (95% CI = 326 to 540 minutes) during guideline use and 710 minutes (95% CI = 558 to 862 minutes) before. Appendiceal perforation rate for males was 0.25 (95% CI = 0.14 to 0.36) during guideline use and 0.38 (95% CI = 0.29 to 0.47) before; perforation rate for females was 0.06 (95% CI = -0.05 to 0.17) during guideline use and 0.23 (95% CI = 0.14 to 0.32) before. Helical CT had 92% sensitivity, 97% specificity, and 96% accuracy in diagnosing appendicitis. CONCLUSIONS: Helical CT is highly accurate in detecting appendicitis in patients with equivocal ED presentations. The use of a guideline employing selective helical CT was associated with a decline in the time from ED presentation to operative intervention in females.
