The role of emergency department computed tomography in early acute pancreatitis.

INTRODUCTION: Computed tomography (CT) is often ordered for patients in whom the diagnosis of acute pancreatitis (AP) has already been established via elevated lipase levels and typical abdominal pain. We investigated whether early CT imaging performed in the ED altered the diagnosis or management. METHODS: A retrospective chart review was performed on patients presenting to a large, academic ED between the years 2013-2015 with AP who received CT imaging. Relevant history, laboratory, imaging data, and hospital course were abstracted from the medical record and analyzed by three independent reviewers, with 100% agreement among reviewers on 30 randomly selected cases. The primary outcome was whether the CT led to a change in diagnosis or management above and beyond the ultrasound. Univariate and multivariate analyses were performed to determine association between predictor variables and outcomes. RESULTS: The electronic health record query yielded 458 patients. Of those, 174 met the American College of Gastroenterology criteria for AP and were included in the study. 145 patients (83%) had abdominal CT during their hospital course, 125 (86%) of which were performed in the ED. Of these 145 patients, 57 (39%) had imaging evidence of AP. 107 patients had abdominal ultrasound (US) during their hospital course. Of 84 patients who had both CT and US, 31 (37%) patients were diagnosed with gallstones by US versus 19 (23%) by CT. Biliary dilation/obstruction was diagnosed by US in 5 (6%) patients versus 4 (5%) by CT. CT led to the correct diagnosis or change in management in 21 (14.5%) patients. CONCLUSION: Early CT may alter the diagnosis or management in up to 15% of patients presenting to the ED with AP, especially older patients with prior episodes of pancreatitis and biliary interventions, however abdominal US may be a more sensitive screening study for biliary etiologies and thereby better direct further management.

The Utility of Midline Intravenous Catheters in Critically Ill Emergency Department Patients.

STUDY OBJECTIVE: Midline catheters are an alternative to more invasive types of vascular access in patients in whom obtaining peripheral access has proven difficult. Little is known of the safety and utility of midline catheters when used more broadly in critically ill patients in the emergency department (ED). These are long peripheral catheter, ranging from 10 to 25 cm in length, typically placed with assistance of ultrasound and the Seldinger's technique. We describe our experience with the use of midline catheters in the ED. METHODS: We conducted a prospective observational case series of all patients who had a midline catheter insertion attempted in the ED. We prospectively captured data on indication, technique, location, catheter type, number of attempts, overall success or failure, vasoactive use, and complications (daily catheter patency, flow, site appearance, and dwell-time complications). RESULTS: From January 28, 2016, to December 30, 2017, practitioners placed 403 midline catheters. Catheter insertion success was 99%, and the median number of attempts was 1 (interquartile range 1 to 1; minimum 1; maximum 3). The median number of days the catheter remained in place was 5 (interquartile range 2 to 8). Failure to aspirate occurred in 57 patients (14%; 95% confidence interval 11% to 18%). Overall, 10 patients (2.5%; 95% confidence interval 1.2% to 4.5%) experienced 10 insertion-related complications. During the study period, 49 patients (12%; 95% confidence interval 9% to 16%) experienced 60 dwell-time-related complications. Severe complications occurred in 3 patients (0.7%). CONCLUSION: Midline catheters may present a feasible alternative to central venous access in certain critically ill ED patients.

Musculoskeletal Ultrasonography to Diagnose Dislocated Shoulders: A Prospective Cohort.

STUDY OBJECTIVE: Shoulder dislocations are a common injury leading to emergency department presentations. Point-of-care ultrasonography has the potential to reduce radiation and time to diagnosis. We determine the accuracy of a novel point-of-care ultrasonographic technique to diagnose dislocated shoulders. We also investigate its accuracy to detect fractures, time to image acquisition, the optimal cutoff for the glenohumeral distance, and compare the time to diagnose dislocations from triage between point-of-care ultrasonography and radiography. METHODS: This was a multicenter prospective observational study. Ultrasonography fellows and fellowship-trained physicians enrolled a convenience sample of patients with suspected shoulder dislocation. Point-of-care ultrasonography was performed with a novel posterior approach with either a curvilinear or a linear transducer. Shoulder dislocation was confirmed with a 3-view radiograph interpreted by an independent radiologist. Sensitivity, specificity, positive predictive values, and negative predictive values were determined for point-of-care ultrasonography, with radiography as the criterion standard. Time to image acquisition, presence or absence of fracture, glenohumeral distance, sonographer confidence, and difference in time to diagnosis from triage for point-of-care ultrasonography and radiograph were also determined. A second investigator independently reviewed all images and interobserver agreement was calculated. RESULTS: Sixty-five patients were enrolled in the study. The sensitivity and specificity of point-of-care ultrasonography for identifying dislocations were 100% (95% confidence interval [CI] 87% to 100%) and 100% (95% CI 87% to 100%), respectively. Point-of-care ultrasonography was 92% sensitive (95% CI 60% to 99.6%) and 100% specific (95% CI 92% to 100%) for non-Hill-Sachs/Bankart's fractures of the humerus. Point-of-care ultrasonography was faster from triage than standard radiology in diagnosing dislocations (median difference 43 minutes; interquartile range [IQR] 23 to 60 minutes). The median total time required for diagnosis by point-of-care ultrasonography was 19 seconds (IQR 10 to 36 seconds). The median glenohumeral distance was -1.83 cm (IQR -1.98 to -1.41 cm) in anterior dislocations, 0.22 cm (IQR 0.10 to 0.35 cm) on nondislocated shoulders, and 3.30 cm (IQR 2.59 to 4.00 cm) in posterior dislocations. CONCLUSION: A posterior approach point-of-care ultrasonographic study is a quick and accurate tool to diagnose dislocated shoulders. Ultrasonography was also able to accurately identify humeral fractures and significantly reduce the time to diagnosis from triage compared with standard radiography.

Cohort of Four Thousand Four Hundred Four Persons Under Investigation for COVID-19 in a New York Hospital and Predictors of ICU Care and Ventilation.

Study objective: Most coronavirus disease 2019 (COVID-19) reports have focused on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive patients. However, at initial presentation, most patients' viral status is unknown. Determination of factors that predict initial and subsequent need for ICU and invasive mechanical ventilation is critical for resource planning and allocation. We describe our experience with 4,404 persons under investigation and explore predictors of ICU care and invasive mechanical ventilation at a New York COVID-19 epicenter. Methods: We conducted a retrospective cohort study of all persons under investigation and presenting to a large academic medical center emergency department (ED) in New York State with symptoms suggestive of COVID-19. The association between patient predictor variables and SARS-CoV-2 status, ICU admission, invasive mechanical ventilation, and mortality was explored with univariate and multivariate analyses. Results: Between March 12 and April 14, 2020, we treated 4,404 persons under investigation for COVID-19 infection, of whom 68% were discharged home, 29% were admitted to a regular floor, and 3% to an ICU. One thousand six hundred fifty-one of 3,369 patients tested have had SARS-CoV-2-positive results to date. Of patients with regular floor admissions, 13% were subsequently upgraded to the ICU after a median of 62 hours (interquartile range 28 to 106 hours). Fifty patients required invasive mechanical ventilation in the ED, 4 required out-of-hospital invasive mechanical ventilation, and another 167 subsequently required invasive mechanical ventilation in a median of 60 hours (interquartile range 26 to 99) hours after admission. Testing positive for SARS-CoV-2 and lower oxygen saturations were associated with need for ICU and invasive mechanical ventilation, and with death. High respiratory rates were associated with the need for ICU care. Conclusion: Persons under investigation for COVID-19 infection contribute significantly to the health care burden beyond those ruling in for SARS-CoV-2. For every 100 admitted persons under investigation, 9 will require ICU stay, invasive mechanical ventilation, or both on arrival and another 12 within 2 to 3 days of hospital admission, especially persons under investigation with lower oxygen saturations and positive SARS-CoV-2 swab results. This information should help hospitals manage the pandemic efficiently.

Association of Pain Location With Computed Tomography Abnormalities in Emergeny Department Patients With Abdominal Pain.

BACKGROUND: Over the last decade the usage of computed tomography (CT) imaging has risen dramatically in emergency department (ED) patients with abdominal pain. Recognizing the potential disadvantages of overuse of CT imaging, efforts are being made to reduce imaging. OBJECTIVE: We determined the operating characteristics for location of abdominal pain for the entities of acute appendicitis, diverticulitis, and intestinal obstruction. We hypothesized that patients with pain localized to the upper abdomen would be less likely to have CT abnormalities than those with lower abdominal pain. METHODS: This is a prospective, observational registry of ED patients with abdominal pain, performed in an academic, suburban ED with an annual census of 110,000. Presence of clinically significant CT abnormalities (e.g., appendicitis, diverticulitis, bowel obstruction) were recorded along with clinical variables including laboratory values, vital signs, reported location of pain, location of tenderness on examination, and physician pretest probability. RESULTS: A convenience sample of 1154 patients was enrolled. Of all patients, 273 cases (24%) had abnormal CT results, including appendicitis (n = 95), diverticulitis (n = 133), and bowel obstruction (n = 49). Right upper quadrant pain was negatively associated with abnormal CT (p = 0.02). Clinician gestalt was highly specific, but lacked sensitivity for the diagnosis of appendicitis, diverticulitis, and obstruction. Twenty-four percent of patients diagnosed with appendicitis had no right lower quadrant pain or tenderness, and 7% of patients with diverticulitis had no left lower quadrant pain or tenderness. CONCLUSIONS: Localization of abdominal pain by history or physical examination is not sufficient to accurately diagnose intra-abdominal pathology, especially cases of acute appendicitis, diverticulitis, or intestinal obstruction.

Team Triage Intervention, Including Licensed Practical Nurse, to Increase HIV Testing Rates in the Emergency Department: A Quality Improvement Project.

INTRODUCTION: Emergency departments have an important role in screening for human immunodeficiency virus infection and reducing the morbidity, mortality, and transmission of the human immunodeficiency virus. There are debates about human immunodeficiency virus screening, including opt-in, opt-out, and active choice models. Previous studies have shown that multiple factors affect the patient rate of acceptance, including where, when, and by whom the screening is offered. The purpose of this quality improvement project was to test a team-based triage intervention to improve the amount of HIV testing done in our emergency department. METHODS: The design was a single site quality improvement intervention with post-intervention monthly rates compared to historic monthly rate controls. The intervention focused on the introduction of a Licensed Practical Nurse in addition to the current triage process and personnel. The percentage of patients receiving human immunodeficiency virus testing and the number of tests sent per month before and after the implementation of the intervention were measured. RESULTS: Our results show that 0.6% (SD < 0.01) and 2.5% (SD 2.2) of patients received human immunodeficiency virus testing before and after implementation of the intervention, respectively (χ2 = 501.76, P < 0.05). A mean of 37.4 (SD = 12.91) and 151.3 (SD = 33.34) human immunodeficiency virus tests were sent per month before and after implementation of the intervention, respectively (t = 8.53, P < 0.001). DISCUSSION: This process intervention, in which licensed practical nurses offered human immunodeficiency virus screening tests during team triage, resulted in a 3-fold increase in the percentage of patients being tested for human immunodeficiency virus.

Ultrasound for the Diagnosis and Management of Suspected Urolithiasis in the Emergency Department.

BACKGROUND: This review provides practicing emergency physicians updated information regarding point-of-care ultrasound (POCUS) imaging of patients with suspected urolithiasis. METHODS: A PubMed literature search was conducted for articles published between January 1, 1996 and May 31, 2017 and limited to human clinical trials written in English with relevant keywords. High-quality studies identified then underwent a structured review. Recommendations herein are made based on the literature review. RESULTS: Two hundred seventy-two abstracts fulfilling the search criteria were screened and 10 appropriate articles were rigorously reviewed in detail. There were 8 prospective studies and 2 retrospective studies. Only 1 of them was a multi-institutional randomized trial. POCUS performed in the emergency department (ED) is moderately sensitive and specific in making the diagnosis of urolithiasis in symptomatic patients. Suspected urolithiasis patients evaluated initially with ED POCUS have complication rates compatible with those evaluated initially with computed tomography. CONCLUSIONS: POCUS has moderate accuracy in making the diagnosis of urolithiasis. Nevertheless, it may be safely used as a first line of imaging in ED patients with suspected symptomatic urolithiaisis.

Evaluation of emergency medicine discharge instructions in pediatric head injury.

OBJECTIVES: Pediatric head trauma is a common occurrence. There is mounting evidence that even patients with minor head injury require limits on school activities and/or removal from sports and play to help speed recovery and limit morbidity. The objective of this study was to determine whether discharge instructions given to children who had sustained head injuries included information regarding activity restrictions, activity time constraints, and/or specifics of follow-up care. METHODS: This was a retrospective chart review of patients aged 2 to 18 years evaluated and treated for head injury during a 4-month period at a level I trauma center (volume ∼23,000 pediatric patients per year). Included were those children seen, evaluated, and diagnosed with any of the following: mild head injury, concussion, minor head trauma, or mild traumatic brain injury (mTBI). Subjects were excluded if there was a positive acute head injury computed tomography finding (other than findings of a simple linear skull fracture) or if the subject required admission. RESULTS: Among the 204 patients meeting eligibility, 95.1% received instruction to follow up with a physician, 82.8% received anticipatory guidance regarding expected symptoms, 15.2% received specific restriction time from sports, and 21.5% were removed from sports. Of these patients, 113 patients were determined "likely" to have sustained an mTBI. Patients with sports-related mTBI received return-to-sports restrictions (χ2 = 11.225, P < 0.008) and to remove the child from play (χ2 = 9.781, P < 0.004) as discharge instructions significantly more than did patients with motor vehicle accident or other mechanisms of injury. CONCLUSIONS: Children sustaining head injury were inadequately instructed to restrict athletic activities upon discharge. This is particularly true for patients who sustain an mTBI from non-sports-related activity.

Licensed Practical Nurses in Team Triage: A Safe Way to Address Nursing Shortages in the Emergency Department.

Background There is a Registered Nurse (RN) shortage across the United States that is predicted to intensify in the upcoming years. RNs are an integral part of Emergency Departments (EDs) and perform many vital tasks, including IV placement, blood draws, medication administration, acute assessments, and patient hand-offs. Thus, RN staffing is a crucial part of ED operations, and ED initiatives should account for RN workforce shortages. Given the increase in ED visits and crowding, throughput initiatives that can expedite patient care are integral to the functioning of an ED. Team Triage is a throughput initiative that has been shown to improve ED time to provider, length of stay, and left without being seen rates. In our institution, we created a Team Triage model where advanced practice providers (APPs) perform a patient's initial evaluation in triage and place orders for labs, intravenous (IV) catheters, and imaging. Given the RN staffing shortage, we incorporated Licensed Practical Nurses (LPNs) in Team Triage to place IV catheters and draw blood work for laboratory tests. The objective of this investigation was to describe a Team Triage model that incorporated LPNs and to report the patient safety and productivity of this model. Methods This was a single-site retrospective study at a large, academic, tertiary care center with over 100,000 annual visits. Adult patients who self-presented to the ED and went through Team Triage (11 am-11 pm) between Jan 1, 2020, and Jan 31, 2020, were included in this study. LPNs staffed the Team Triage, along with APPs. LPNs placed IV catheters and drew blood specimens for the Team Triage patients. The primary outcomes studied were the proportion of specimens mislabeled by LPNs, the proportion of patients receiving IV catheters, the proportion of patients receiving blood work, blood tubes drawn per hour, and IVs inserted per hour in Team Triage. Results During the study period, 1355 patients went through Team Triage. Of these patients, 1075 (79%) were ordered for blood work, and 1017 (75%) were ordered for an IV catheter. All Team Triage blood work and IV catheter placements were completed by LPNs, who staffed 372 hours of Team Triage. A total of 2558 blood tubes were collected by LPNs. The LPNs cared for 2.9 patients per hour, collected 6.9 blood tubes per hour, inserted 2.7 IV catheters per hour, and collected 2.4 blood tubes per patient. The LPNs had a 0% specimen mislabeling rate. Conclusion Due to the significant RN workforce shortage impacting Emergency Medicine coupled with increased ED crowding, there is a significant need to evaluate the integration of LPNs into Team Triage to place IV catheters and perform blood draws. This study shows that incorporating LPNs in Team Triage is a productive and safe way to address nursing shortages in Emergency Medicine.

Impact of HEART Score Decision Aid on Coronary Computed Tomography Angiography Utilization and Diagnostic Yield in the Emergency Department.

OBJECTIVE: Emergency physicians are challenged to efficiently and reliably risk stratify patients presenting with chest pain (CP) to optimize diagnostic testing and avoid unnecessary hospital admissions. The objective of our study was to evaluate the impact of a HEART score-based decision aid (HSDA) integrated in the electronic health record on coronary computed tomography angiography (CCTA) utilization and diagnostic yield in adult emergency department (ED) CP patients with suspected acute coronary syndrome. METHODS: We conducted a before and after study to determine whether implementation of a mandatory computerized HSDA would reduce CCTA utilization in ED CP patients and improve the diagnostic yield of obstructive coronary artery disease (CAD) (≥50%). We included all adult ED CP patients with suspected acute coronary syndrome during the first 6 months of 2018 (before) and 2020 (after) at a large academic center. CCTA utilization and obstructive CAD yield were compared in patients before and after implementing the HSDA using χ2 tests. Secondarily, we assessed the association of HEART scores and CCTA results. RESULTS: Of the 3095 CP patients during the before study period, 733 underwent CCTA. Of the 2692 CP patients during the after study period, 339 underwent CCTA. CCTA utilization before and after HSDA was 23.4% [95% confidence interval (95% CI), 22.2-25.2] and 12.6% (95% CI, 11.4-13.0), respectively; mean difference was 11.1% (95% CI, 0.9-13.0). Among 1072 patients undergoing CCTA, mean (SD) age and percent females before versus after HSDA were 54 (11) versus 56 (11) years and 50% versus 49%, respectively. We included 1014 patients (686 before and 328 after) for the yield analysis. Obstructive CAD was present in 15% (95% CI, 12.7-17.9) and 20.1% (95% CI, 16.1-24.7) before and after HSDA, respectively; mean difference was 4.9% (95% CI, 0.1-10.1). CONCLUSIONS: Implementation of a mandatory electronic health record HSDA aid reduced ED CCTA utilization by half and improved the diagnostic yield.

Rates of positive blood, urine, and cerebrospinal fluid cultures in children younger than 60 days during the vaccination era.

BACKGROUND: Fever is a common reason children present to the emergency department. The goal of this study was to determine the rates and the etiology of bacterial infection in children younger than 2 months during the vaccination era. METHODS: This is a retrospective chart review performed at a tertiary care hospital. Electronic medical records were used to identify patients who had a workup for fever/sepsis in the emergency department. The search was limited to identifying only children younger than 60 days. RESULTS: A total of 207 patients satisfied the inclusion/exclusion criteria. In children younger than 28 days, the blood culture-positive rate was 2.7% (range, 0.0%-6.4%), the urine culture-positive rate was 10.7% (range, 3.5%-17.8%), and the cerebrospinal fluid-positive rate (excluding enteroviral infections) was 0% (range, 0.0%-3.9%). In children 29 to 60 days, the blood culture-positive rate was 1.5% (range, 0.0%-3.6%), urine culture-positive rate was 8.5% (range, 3.7%-13.3%), and the cerebrospinal fluid-positive rate (excluding enteroviral infections) was 1.7% (range, 0.0%-5.0%). Urinary tract infections due to Escherichia coli were very common, whereas no cases of Haemophilus influenzae and one case of Streptococcus pneumoniae were detected. CONCLUSIONS: Urinary tract infections due to E. coli are very common in this age group. The classic pathogens H. influenzae and S. pneumoniae were essentially nonexistent in this study possibly because of herd immunity obtained through current vaccination practices.

Rapid creation of an emergency department telehealth program during the COVID-19 pandemic.

Coronavirus disease 2019 (COVID-19) has spread to nearly every continent, with over 2.6 m cases confirmed worldwide. Emergency departments care for a significant number of patients who are under investigation for COVID-19 or are COVID-19-positive. When patients present in the emergency department, there is an increased risk of spreading the virus to other patients and staff. We designed an emergency department telehealth program for patients physically in the emergency department, to reduce exposure and conserve personal protective equipment. While traditional telehealth is designed to be patient-specific and device-independent, our emergency department telehealth program was device-specific and patient-independent. In this article, we describe how we rapidly implemented our emergency department telehealth program, used for 880 min of contact time and 523 patient encounters in a 30-day period, which decreased exposure to COVID-19 and conserved personal protective equipment. We share our challenges, successes and recommendations for designing an emergency department telehealth program, building the technological aspects, and deploying telehealth devices in the emergency department environment. Our recommendations can be adopted by other emergency departments to create and run their own emergency department telehealth initiatives.

Team triage increases discharges and decreases time to discharge without increasing test ordering.

OBJECTIVES: Emergency department (ED) crowding is detrimental to patients and staff. During traditional triage, nurses evaluate patients and identify their level of emergency. During team triage, physicians and/or nurse practitioners (NPs) and physician assistants (PAs) place orders, laboratory results, intravenous lines (IVs), and imaging in triage. Team triage improves access to testing and decreases length of stay. However, ordering practices in team triage may lead to overtesting. METHODS: This is a retrospective review of patients seen before and after a team triage process was established. Percentage of patients receiving testing and the diagnostic yields of troponins, lactates, international normalized ratios (INRs), blood cultures, glomerular filtration rates (GFR), and head computed tomography (CT) images were studied. RESULTS: A total of 704 traditionally triaged patients and 862 team triaged patients met inclusion criteria. Comparing traditional versus team triaged patients, the proportion of patients discharged was 0.44 versus 0.53 (P < 0.001), and the length of stay to discharge was 417 versus 375 minutes (P = 0.003). Comparing traditional versus team triage, a head CT was obtained 12.5% versus 5.7% (P < 0.001) of the time with diagnostic yield 45.5% versus 52% (not significant), troponin was obtained 51.3% versus 45.9% (not significant) of the time with diagnostic yield 14.9% versus 13.9% (not significant), lactate was obtained 41.6% versus 32.1% (P = 0.011) of the time with diagnostic yield 18.4% versus 12.3% (not significant), INR was obtained 70.2% versus 55.8% (P = 0.007) of the time with diagnostic yield 15.8% versus 10.5% (P = 0. 042), GFR was obtained 99.3% versus 98.4% (not significant) of the time with diagnostic yield 18.9% versus 13.7% (P = 0.02), and blood cultures were obtained 23.4% versus 7.3% (P < 0.001) of the time with diagnostic yield 7.3% versus 9.3% (not significant). CONCLUSION: Compared with traditional triage, the team triage process increased discharges and decreased time to discharge, but did not lead to increased testing or decreased diagnostic yield.

Outcomes and Healthcare Provider Perceptions of Real-Time Continuous Glucose Monitoring (rtCGM) in Patients With Diabetes and COVID-19 Admitted to the ICU.

OBJECTIVE: We assessed the clinical utility and accuracy of real-time continuous glucose monitoring (rtCGM) (Dexcom G6) in managing diabetes patients with severe COVID-19 infection following admission to the intensive care unit (ICU). METHODS: We present retrospective analysis of masked rtCGM in 30 patients with severe COVID-19. rtCGM was used during the first 24 hours for comparison with arterial-line point of care (POC) values, where clinicians utilized rtCGM data to adjust insulin therapy in patients if rtCGM values were within 20% of point-of-care (POC) values during the masked period. An investigator-developed survey was administered to assess nursing staff (n = 66) perceptions regarding the use of rtCGM in the ICU. RESULTS: rtCGM data were used to adjust insulin therapy in 30 patients. Discordance between rtCGM and POC glucose values were observed in 11 patients but the differences were not considered clinically significant. Mean sensor glucose decreased from 235.7 ± 42.1 mg/dL (13.1 ± 2.1 mmol/L) to 202.7 ± 37.6 mg/dL (11.1 ± 2.1 mmol/L) with rtCGM management. Improvements in mean sensor glucose were observed in 77% of patients (n = 23) with concomitant reductions in daily POC measurements in 50% of patients (n = 15) with rtCGM management. The majority (63%) of nurses reported that rtCGM was helpful for improving care for patients with diabetes patients during the COVID-19 pandemic, and 49% indicated that rtCGM reduced their use of personal protective equipment (PPE). CONCLUSIONS: Our findings provide a strong rationale to increase clinician awareness for the adoption and implementation of rtCGM systems in the ICU. Additional studies are needed to further understand the utility of rtCGM in critically ill patients and other clinical care settings.

Functional status after injury: a longitudinal study of geriatric trauma.

We evaluated self-rated functional status measured longitudinally in the year after injury in a geriatric trauma population. The longitudinal (L) group included 37 of 60 eligible trauma patients aged 65 years or older admitted December 2006 to November 2007 for greater than 24 hours who completed a Short Functional Status questionnaire (SFS) at 3, 6, and 12 months after injury. The SFS yields scores of 0 to 5 (5 = independent in all five activities of daily living [ADLs]) and has been validated among community-dwelling elders. The control (C) group included 63 trauma patients aged 65 years or older admitted December 2007 to July 2009 for greater than 24 hours who reported their preinjury functional status using the SFS at hospital admission. We used characteristics and scores of the C group to impute preinjury ADL scores for the L group. The groups were similar in baseline characteristics (age, ethnicity, Injury Severity Score, Charlson Comorbidity Index, and living arrangement; P > 0.05). For the C group, the preinjury ADL score was 4.6 (SD = 0.9). For the L group, ADL scores declined at all intervals reaching statistical significance at 12 months. We conclude that in the year after traumatic injury, geriatric patients lost the equivalent of approximately one ADL, increasing their risk of further functional decline, loss of independence, and death.

Impact of Education-based HEART Score Pathway on Coronary Computed Tomography Angiography Utilization and Yield in the Emergency Department.

OBJECTIVE: There is a growing consensus to reduce unnecessary testing among low-risk chest pain patients. The objective of this study was to evaluate the impact of implementing an education-based HEART score pathway in the emergency department on coronary computed tomography angiography (CCTA) utilization and yield. METHODS: A retrospective before and after intervention study was conducted at a single site. Adult emergency department patients undergoing CCTA for suspected acute coronary syndrome were included. Primary outcomes were CCTA utilization and yield. Utilization was defined as the percentage of patients evaluated with CCTA and yield was calculated as the percentage of patients with a diagnosis of obstructive coronary artery disease, defined as ≥50% stenosis in any one coronary artery due to atherosclerosis. RESULTS: 1540 patients undergoing CCTAs were included. CCTA utilization before and after were 2.2% [95% confidence interval (CI) 2.0-2.3] and 2.0% (95% CI 1.9-2.2), respectively; mean difference 0.1% (95% CI -0.1 to 0.3; P = 0.21). The mean age was 53 years (SD = 11) and females were 52%. Of 1477 patients included in CCTA yield analysis, patients diagnosed with obstructive coronary artery disease before and after were 15.0% (95% CI 12.6-17.7) and 16.2% (95% CI 13.6-19.1), respectively; mean difference 1.2% (95% CI -2.6 to 5.1; P = 0.53). CONCLUSIONS: There was no significant change in the CCTA utilization or yield after the implementation of an education-based HEART pathway in a large academic center. Our findings suggest adopting a more comprehensive approach for deploying such evidence-based protocols to increase institutional compliance.

Body mass index and pediatric asthma outcomes.

OBJECTIVE: The purpose of this study was to determine the association between body mass index (BMI), a measure of obesity, with emergency department admission rate in children with asthma. METHODS: This was a prospective study in a tertiary care, urban pediatric emergency department. Treating physicians and academic associates enrolled subjects during June 2005 to April 2008. Eligible subjects with documented weight and height were between ages 6 and 18 years with chief complaint of wheezing. We compared admission rates between overweight children (BMI, > or = 85% percentile) and nonoverweight children (BMI, < 85% percentile). Data were expressed as mean (SD). Group comparisons were made by Student t test or Fisher exact test, as appropriate. All tests were 2-tailed with an alpha set at 0.05. RESULT: We studied 183 children, where 108 children were classified overweight. Demographic differences (mean age, male sex, and African-American race) between overweight and nonoverweight children were not statistically significant. In addition, changes in asthma outcome measures (inpatient admissions during the previous year, asthma visits in the last 30 days, and missed school days in the last 30 days) were not statistically significant. Only household tobacco use approached statistical significance (P = 0.07). The admission rate for nonoverweight children was 9.3% (95% confidence interval [CI], 4.3-18.3) compared with the 10.2% (95% CI, 5.6-17.5) for overweight children; a P = 1.0 was equivalent. CONCLUSIONS: Body mass index, a method to quantify overweight children, failed to predict admission of children with ambulatory asthma who presented to the pediatric emergency department.

Blunt cardiac injury: emergency department diagnosis and management.

Blunt cardiac injury describes a range of cardiac injury patterns resulting from blunt force trauma to the chest. Due to the multitude of potential anatomical injuries blunt force trauma can cause, the clinical manifestations may range from simple ectopic beats to fulminant cardiac failure and death. Because there is no definitive, gold-standard diagnostic test for cardiac injury, the emergency clinician must utilize an enhanced index of suspicion in the clinical setting combined with an evidence-based diagnostic testing approach in order to arrive at the diagnosis. This review focuses on the clinical cues, diagnostic testing, and clinical manifestations of blunt cardiac injury as well as best-practice management strategies.
