Weekend Emergency Department Visits in Nebraska: Higher Utilization,Lower Acuity

Background: We know very little about differences in Emergency Department (ED) utilization and acuity on weekends compared with weekdays. Understanding such differences may help elucidate the role of the ED in the health care delivery system. Study Objective: To compare patterns of ED use on weekends with weekdays and analyze the differences between these two groups. Methods: The Health Care Utilization Project (HCUP) is a national state-by-state billing database from acute-care, non-federal hospitals. Data from Nebraska in 2004 was used to compare ED-only patient visits (patients discharged home or transferred to another health care facility) and ED-admitted visits (patients admitted to the same hospital after an ED visit) for weekend vs. weekday frequency, billed charges, sex, age, and primary payer. Results: Of all non-admitted patients who visited the ED, 34.5% came in on weekends. This yielded ED utilization rates of 25 visits/1000 people on weekdays and 33 visits/1000 people on weekends, an increase of 32% on weekends. Weekend-only ED patients of all ages and payer categories were charged lower hospital facility fees than weekday-only ED patients; $777 vs. $921, respectively (p < 0.001). Weekend ED patients were less likely to be admitted and less likely to die while in the ED (2 deaths/1000 ED visits for weekend-only patients vs. 3 deaths/1000 ED visits for weekday-only [p < 0.001]). Conclusions: In Nebraska, EDs care for a greater number of low-acuity patients on weekends than on weekdays. This highlights the important role EDs play within the ambulatory care delivery system.     

Chest radiograph vs. computed tomography scan in the evaluation for pneumonia

To determine, in an Emergency Department (ED) population, the incidence of pneumonia diagnosed on thoracic computed tomography (CT) in the setting of negative or non-diagnostic chest radiographs (CXR). This is a retrospective chart review of all ED visits of adult patients ultimately diagnosed with "pneumonia" in whom both CXR and CT were obtained. We note cases in which the CXR was either negative or non-diagnostic for pneumonia and the CT noted a definitive infiltrate consistent with pneumonia. Of the 1,057 patients diagnosed with pneumonia, both CXR and CT were performed in 97 cases. Of this group, there were 26 patients (27%), in whom the CXR was either negative or non-diagnostic, but the CT noted an infiltrate/consolidation consistent with pneumonia. In our retrospective review of ED patients, we find that in 27% of cases in which both a CXR and a CT scan were performed in the work-up of varied chief complaints, pneumonia was demonstrated on CT in the face of a negative or non-diagnostic CXR. This analysis demonstrates the need for further studies regarding the appropriate radiographic evaluation of pneumonia, particularly in high-risk patients.     

Educating Emergency Department Registered Nurses (EDRNs) in screening,brief intervention,and referral to treatment (SBIRT): Changes in attitudes and knowledge over time

Alcohol and other drug (AOD) diagnoses in the ED co-occur with injury-related presenting conditions including: falls, motor vehicle accidents, poisonings, and both intentional and unintentional injuries. Clinical attention to ED admissions resulting from hazardous AOD use can significantly improve patient care and reduce high cost utilization of ED visits and treatment. The EDRN-SBIRT project is designed to improve the knowledge and attitudes of ED nurses working in a large academic medical center to identify and address risky AOD use as it relates to an ED visit. ED nurses’ knowledge and attitudes toward patients with AOD use can be improved through SBIRT education. SBIRT education can establish an evidence-based standard of nursing practice to improve healthcare outcomes, but it must be reinforced with ongoing ED review and supportive educational sessions until practice is firmly established.     

Food Security,Health, and Medication Expenditures of Emergency Department Patients

Background: In the United States, 35 million people live in food-insecure households. Although food insecurity and hunger are undesirable in their own right, they also are potential precursors to nutritional, health, and developmental problems. Study Objectives: To examine the prevalence of household food insecurity and its association with health problems and medication expenditures among Emergency Department (ED) patients. Methods: We conducted a cross-sectional study in four Boston-area EDs and enrolled consecutive adult patients during two 24-h periods at each site. Food security status was measured using the validated 18-item US Household Food Security Survey Module. Results: Overall, 66 (13%; 95% confidence interval [CI] 10–17%) of 520 ED patients screened positive for food insecurity. Among these 66 patients, 32 (48%; 95% CI 36–61%) reported food insecurity with hunger. Patients from food-insecure households differed from food-secure patients with respect to sociodemographic factors. Food-insecure patients were more likely than food-secure patients to report a variety of chronic and mental health problems (all p < 0.05), including obesity. Food-insecure patients, compared to food-secure patients, also were more likely (all p < 0.001) to put off paying for medication to have money for food (27% vs. 4%, respectively), to take medication less often because they couldn't afford more (32% vs. 4%, respectively), to report needing to make a choice between buying medication and food (27% vs. 2%, respectively), and to report getting sick because they couldn't afford to take medication (27% vs. 1%, respectively). Conclusions: ED patients from food-insecure households report more chronic and mental health problems, and difficulty purchasing medication.     

Emergency Department Characteristics and Capabilities in Beijing, China

Background

Emergency Departments (EDs) are a critical, yet heterogeneous, part of international emergency care.

Objectives

We sought to describe the characteristics, resources, capabilities, and capacity of EDs in Beijing, China.

Methods

Beijing EDs accessible to the general public 24 h per day/7 days per week were surveyed using the National ED Inventories survey instrument (www.emnet-nedi.org). ED staff were asked about ED characteristics during the calendar year 2008.

Results

Thirty-six EDs participated (88% response rate). All were located in hospitals and were independent hospital departments. Participating EDs saw a median of 80,000 patients (interquartile range 40,000–118,508). The vast majority (91%; 95% confidence interval [CI] 78–98%) had a contiguous layout, with medical and surgical care provided in one area. Most EDs (55%) saw only adults; 39% saw both adults and children, and 6% saw only children. Availability of technological and consultant resource in EDs was high. The typical ED length of stay was between 1 and 6 h in 49% of EDs (95% CI 32–67%), whereas in the other half, patients reportedly remained for over 6 h; 36% (95% CI 21–54%) of respondents considered their ED over capacity.

Conclusions

Beijing EDs have high volume, long length of stay, and frequent reports of EDs being over capacity. To meet its rapidly growing health needs in urban areas, China should consider improving urban ED capacity and training more Emergency Medicine specialists capable of efficiently staffing its crowded EDs.     

National study on the frequency, types, causes, and consequences of voluntarily reported emergency department medication errors

Background: Medication errors contribute to significant morbidity, mortality, and costs to the health system. Little is known about the characteristics of Emergency Department (ED) medication errors. Study Objective: To examine the frequency, types, causes, and consequences of voluntarily reported ED medication errors in the United States. Methods: A cross-sectional study of all ED errors reported to the MEDMARX system between 2000 and 2004. MEDMARX is an anonymous, confidential, de-identified, Internet-accessible medication error-reporting program designed to allow hospitals to report, track, and share error data in a standardized format. Results: There were 13,932 medication errors from 496 EDs analyzed. The error rate was 78 reports per 100,000 visits. Physicians were responsible for 24% of errors, nurses for 54%. Errors most commonly occurred in the administration phase (36%). The most common type of error was improper dose/quantity (18%). Leading causes were not following procedure/protocol (17%), and poor communication (11%), whereas contributing factors were distractions (7.5%), emergency situations (4.1%), and workload increase (3.4%). Computerized provider order entry caused 2.5% of errors. Harm resulted in 3% of errors. Actions taken as a result of the error included informing the staff member who committed the error (26%), enhancing communication (26%), and providing additional training (12%). Patients or family members were notified about medication errors 2.7% of the time. Conclusion: ED medication errors may be a result of the acute, crowded, and fast-paced nature of care. Further research is needed to identify interventions to reduce these risks and evaluate the effectiveness of these interventions.     

Pediatric Visits to United States Emergency Departments for Alcohol-Related Disorders

Background

The use of alcohol by pediatric patients has not been thoroughly examined in the United States (US). Patients with complaints related to alcohol use frequently present to the Emergency Department initially.

Objective

Our aim was to determine the number of pediatric patients (ages 17 years and younger) presenting to Emergency Departments (EDs) in the US from 2006 to 2008 for alcohol-related disorders and examine selected clinical and demographic features of this population.

Methods

This was a retrospective cohort study using 3 years (2006–2008) of data from the Nationwide Emergency Department Sample. This database was used to identify patients younger than 18 years of age with an alcohol-related ED visit, and clinical and demographic features were examined.

Results

From 2006 to 2008, a total of 218,514 pediatric patients presented to US EDs and received a subsequent diagnosis of an alcohol-related disorder. Mean age of patients was 15.61 years. Most patients were male and tended to be from higher-income communities.

Conclusions

There were 218,514 visits to US EDs by patients younger than 18 years of age for alcohol-related disorders, accounting for >$850 million dollars in charges. ED-based brief alcohol interventions shown to work in adult populations should be explored for use in pediatric patients.

Approach to a Patient with Diplopia in the Emergency Department

Background

Diplopia can be the result of benign or life-threatening etiologies. It is imperative for the emergency physician to be proficient at assessing diplopia and recognize when urgent referral or neuroimaging is required.

Proteomic approach to the diagnosis of acute coronary syndrome: preliminary results

BACKGROUND: Cardiac multimarker strategy is recommended by the IFCC, ESC and the ACC for an early risk stratification in non-ST-segment elevation (NSTE) ECG patients with chest pain. A new approach, based on protein biochip array technology, performs simultaneously: cTnI, CK-MB, myoglobin, CAIII, GFBB and FABP using a single chip. METHODS: We evaluated the analytical performance of the Randox-Evidence Investigator -biochip cardiac panel according to IFCC recommendations and NCCLS guidelines; a preliminary clinical evaluation was carried out on chest pain NSTE ECG patients, to evaluate the accuracy of the multimarker approach in an early diagnosis of AMI, related to the final diagnosis (ACC/ESC criteria). RESULTS: Troponin, CK-MB and FABP methods provide reproducible within-run and between-day results (total % CVs from 5.9% to 9.7%), and myoglobin and CAIII methods showed the total % CVs from 16.4% to 25.8%. Our preliminary clinical data suggests that FABP had a better diagnostic performance (sensibility = 100%) than myoglobin (sensibility = 75%) to detect AMI in the first hours after the onset of the chest pain and myoglobin/CAIII ratio (specificity = 92.9%) improved the myoglobin specificity. CONCLUSIONS: Cardiac markers have different diagnostic roles and, in this contest, biochip technology could be an interesting approach supporting clinical expectations.     

Diffusion and practice of ultrasound in emergency medicine departments in Italy

Introduction

This paper reports data from a cognitive survey on the diffusion, practice and organization of ultrasound (US) in emergency medicine departments (EMDs) in Italy. The study was carried out by the Emergency Medicine Section of the Italian Society for Ultrasound in Medicine and Biology (SIUMB) in collaboration with the Italian Society for Emergency Medicine and Urgent Care (SIMEU).

Methods

We created a questionnaire with 10 items, relating to 4 thematic areas. The questionnaires were administered from September 2007 to February 2008, by email, telephone or regular mail. In August 2008 the data were subjected to nonparametric statistical analysis (Spearman''s Rho and Pearson''s chi-square – software SPSS).

Results

We analyzed 170 questionnaires from the EMDs of all Italian regions. A US scanner is present in 64.7% of the ERs, emergency US (E-US) is practiced only in 47.6% of the ERs, and only in 24% of these more than 60% of the ER team members have training in US. The diffusion of US in other operative units of the EMDs ranges from 8.2% to 26.5%.

Discussion

The presence of a US scanner in the ER is essential for the practice and training and is correlated with the level of the EMD. The use of US appears to be less common in less equipped hospitals, regardless of the size of the ER and the availability of radiological services. Wider diffusion of US and greater integration with other services for the installment of the required equipment is to be hoped for.     

Septic Arthritis of the Temporomandibular Joint: Case Reports and Review of the Literature

Background

Septic arthritis of the temporomandibular (TM) joint is rare, but it is associated with high risk for significant morbidity.

Objective

We reviewed the available literature regarding the presentation, evaluation, treatment, and clinical course of TM joint septic arthritis, focusing on elements relevant to emergency physicians.

Case Reports

In the first case, a healthy 6-year-old boy presented with fever and trismus; computed tomography with contrast revealed a TM joint effusion. After empiric intravenous antibiotics, intraoperative arthrocentesis of the TM joint returned 1 mL of flocculent fluid, which was cultured and grew pan-sensitive Streptococcus pyogenes. He was discharged home with amoxicillin/clavulanate and experienced complete resolution of his symptoms. In the second case, more than 3 weeks after extraction of her third molars, an 18-year-old woman presented with facial pain, swelling, and trismus and was found to have a loculated abscess involving the left masseteric and pterygomandibular spaces with extension to the left deep temporal region and the skull base. She experienced a complicated postoperative course and required multiple procedures and intravenous antibiotics for growth of multiple bacteria. More than a month later she underwent TM joint arthrotomy for TM joint septic arthritis, and she was found to have acute osteomyelitis. She continued to require multiple treatment modalities; 20 months after her initial presentation, she underwent left total TM joint arthroplasty for fibrous ankylosis of the TM joint.

Conclusion

Septic arthritis of the TM joint may be caused by hematogenous spread of distant infection or local spread of deep masticator space infections. Patients may present with TM joint septic arthritis acutely or sub-acutely. Septic arthritis of the TM joint should be considered in the differential diagnosis of patients who present with trismus and pain or fever.     

Primary headache in Emergency Department: prevalence, clinical features and therapeutical approach

Headache is one of the most common reported complaints in the general adult population and it accounts for between 1% and 3% of admissions to an Emergency Department (ED). The overwhelming majority of patients who present to an ED with acute primary headache (PH) have migraine and very few of them receive a specific diagnosis and then an appropriate treatment. This is due, in part, to a low likelihood of emergency physicians diagnosing the type of PH, in turn due to lack of knowledge of the IHS criteria, and also the clinical condition of the patients (pain, border type of headache, etc.) In agreement with the literature, another interesting aspect of data emerging from our experience is that few of the ED PH patients are referred to headache clinics for diagnosis and treatment, especially if they present with high levels of disability. This attitude promotes the high–cost phenomenon of repeater patients that have already been admitted to the ED for the same reason in the past. This is statistically important because it involves about 10% of the population with PH.     

Breath analyzer screening of emergency department patients suspected of alcohol intoxication

Background

Acute alcohol intoxication is a frequent cause of emergency department (ED) visits. Evaluating a patient’s alcohol intoxication is commonly based on both a physical examination and determination of blood alcohol concentration (BAC).

Objective

To demonstrate the feasibility and usefulness of using a last-generation infrared breath analyzer as a non-invasive and rapid screening tool for alcohol intoxication in the ED.

Methods

Adult patients suspected of acute alcohol intoxication were prospectively enrolled over 10 days. Breath alcohol concentrations (BrAC) were measured using a handheld infrared breath analyzer. BAC was determined simultaneously by automated enzymatic analysis of a venous blood sample. The relationship between BAC and BrAC values was examined by both linear regression and Bland-Altman analysis.

Results

The study included 54 patients (mean age 40 ± 14 years, sex ratio M/F of 3/1). Breath and blood alcohol concentrations ranged from 0 to 1.44 mg/L and from 0 to 4.40 g/L (0–440 mg/dL), respectively. The mean individual BAC/BrAC ratio was 2615 ± 387, 95% confidence interval 2509–2714, which is 30% higher than the legal ratio in France (2000). The correlation between both measurements was excellent: r = 0.95 (0.92–0.97). Linear regression revealed BAC = 0.026 + 1.29 (BrAC × 2000) and BAC = 0.026 + 0.99 (BrAC × 2615). Mean BAC-BrAC differences and limits of agreement were 0.49 g/L [−0.35, 1.34] (or 49 mg/dL [−35, 134] and 0.01 g/L [−0.68, 0.71] (or 1 mg/dL [−68, 71]), for the 2000 and 2615 ratios, respectively.

Conclusion

The calculated conversion coefficient provided a satisfactory determination of blood alcohol concentration. Breath alcohol testing, using appropriate BAC/BrAC conversion, different from the legal BAC/BrAC, could be a reliable alternative for routine screening and management of alcohol intoxication in the ED.     

Comparison of critically ill patients from three freestanding ED's compared to a tertiary care hospital based ED

BackgroundFreestanding emergency departments (FEDs) care for all patients, including critically ill, 24/7/365. We characterized patients from three FEDs transferred to intensive care units (ICU) at a tertiary care hospital, and compared hospital length of stay(LOS) between patients admitted to ICUs from FEDs versus a hospital-based ED (HBED).MethodsWe performed a retrospective, observational cohort study from January 2014 to December 2016. Demographic and clinical information was compared between FED and HBED patients with chi-square and fisher's exact tests for categorical variables and Student's t-test for continuous variables. The main outcome of interest was hospital LOS. Multi-variable linear regression was performed to estimate association between LOS and emergency facility type, while adjusting for potential confounders.ResultsWe included 500 critically ill patients (FED = 250 and HBED = 250). Patients did not differ by age, gender, or BMI. FED patients were more likely to be white (89.6% vs. 70.8%, p < 0.001) and have higher Charlson Co-morbidity Index scores (3.5 vs. 2.4, p < 0.001). Average LOS for FED patients was 5 days, compared to 7 days for HBED patients (p < 0.001). After adjusting for demographic and clinical confounders, there was significant correlation between ED facility type and LOS in hospital (p < 0.001).ConclusionPatients transferred from FEDs to an ICU were similar in age and gender, but more likely to be white with a higher Charlson Comorbidity Index score. FED patients experienced shorter hospital length of stay compared to patients admitted from a HBED.     

Emergency Cesarean Section Due to Acute Aortic Dissection Type A (Debakey I) without Marfan Syndrome: A Case Report and Review of the Literature

Background

Acute aortic dissection during pregnancy is an uncommon but important emergency due to its lethal risk to both mother and child. The dissection usually involves the ascending aorta or the aortic arch. Although additional affection of the descending aorta up to bifurcation is possible, further increasing the risk of organ malperfusion, full-length aortic dissection (DeBakey I) is known to be very rare. Dissection during pregnancy has been reported predominantly in combination with Marfan syndrome. Acute aortic dissection Stanford type A (AADA) DeBakey I during pregnancy without signs of Marfan syndrome as a warning signal is very uncommon in the current literature.

Objectives

The etiology, diagnosis, differential diagnosis, and management of this rare disease are discussed in relation to the current literature.

Case Report

We report the case of an athletic 34-year-old woman in the third trimester of pregnancy, without history of previous diseases, who presented to our Emergency Department after collapsing. In the resuscitation department, an emergency cesarean section was performed due to the start of circulation failure in the mother. Computed tomography scan revealed a severe aortic dissection starting from 1 cm distal the aortic valve over the full length up to the iliac arteries, involving the brachiocephalic and carotid arteries up to the level of the larynx. Emergency replacement of the ascending aorta and the aortic arch was performed. Both the mother and baby survived and were doing well 1 year postoperatively.

Conclusion

This alarming result of AADA (DeBakey I) in late pregnancy without obvious warnings such as Marfan syndrome illustrates the importance of performing early imaging in similar cases.
