Selected AbstractsThe Effects of the Absence of Emergency Medicine Residents in an Academic Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 11 2002Daniel French MD Objective: What are the quality effects of an emergency medicine (EM) residency, and the associated 24/7 supervision of residents by faculty, in an academic emergency department (ED)? The authors evaluated activity and quality indicators when there were no EM residents present. The hypothesis of the study was that there was no difference between the patient care provided by faculty supervising EM residents and that with an alternative model without EM residents (AbsenceEMResident). Methods: To support the weekly residency educational program (Thursday), EM residents are not scheduled clinically for a 24-hour period (ConfDay). Emergency medicine resident coverage (mean 62.7 hours) was replaced with incremental faculty and mid-level providers (mean 41.0 hours). This study was limited to adult patients (22,527 visits of 39,190 ED total) for six months (January,June 2001) and compared indicators for ConfDay (n = 23) with all other days (NotConfDay, n = 158). Results: Comparing ConfDay (2,842 visits) with NotConfDay (19,685 visits), there was no difference in mean daily visits, inpatient admissions, intensive care unit admissions, or emergency medical services arrivals. ConfDay decision-to-admit time (333 vs. 313 min, p = 0.03) and length of stay for admissions (490 vs. 445 min, p = 0.000) were longer, with no difference for treat/release patients. There was no difference in the numbers of laboratory or radiology tests, consultations, unscheduled return visits, or patient satisfaction. Conclusion: During the study period, there was no measurable difference for most of the quality indicators studied. The AbsenceEMResident model is less efficient in admitting patients. Faculty supervision results in the same number of laboratory and radiology tests and consultations. Other specialties may consider this model if off-hours care becomes a concern. [source] Prospective Evaluation of Real-time Use of the Pulmonary Embolism Rule-out Criteria in an Academic Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 9 2010Jeffrey A. Kline MD Abstract Objectives:, The pulmonary embolism rule-out criteria (PERC rule) is a nine-component decision rule derived to exclude pulmonary embolism (PE) without the use of formal diagnostic testing (D-dimer, computed tomography pulmonary angiography, ventilation,perfusion lung scanning, or venous ultrasonography) when all nine components are negative ("PERC negative"). This study examined whether clinicians who document PERC negative also document results of all nine components of the PERC rule. Methods:, This was a pilot study at a single-center, urban teaching emergency department (ED) with a residency program in emergency medicine. Patients were over 17 years of age with at least one of nine predefined chief complaints. Clinicians were asked three questions regarding suspicion for PE, intent to use the PERC rule, and the result. Charts were independently reviewed by two authors for fidelity of the nine PERC components. Patients were followed for PE outcome at 14 days. Results:, The study examined 526 patients cared for by 82 clinicians, who indicated suspicion for PE in 183 of 526 (35%) and intent to use the PERC rule in 115 of 526 (22%) cases, of whom 65 of 115 were documented as PERC negative. No formal test for PE was ordered in 49 of 65 (75%), and 46 of 49 had incomplete documentation to support PERC negative. The most common deficiency was omission of two risk factors for PE in the rule (prior venous thromboembolism or recent surgery). Six patients had PE diagnosed within 14 days, but none of these had been deemed PERC negative. Conclusions:, Clinicians seldom document all nine data elements of the PERC rule in patients they deem PERC negative. These data suggest the need for paper or electronic aids to support use of the PERC rule.

Berger MD Objective: Because many emergency medicine (EM) attending physicians believe the time demands of clinical productivity limit their ability to effectively teach medical students in the emergency department (ED), the purpose of this study was to determine if there is an inverse relationship between clinical productivity and teaching evaluations. Methods: The authors conducted a prospective, observational, double-blind study. They asked senior medical students enrolled in their EM clerkship to evaluate each EM attending physician who precepted them at three academic EDs. After each shift, students anonymously evaluated 10 characteristics of clinical teaching by their supervising attending physician. Each attending physician's clinical productivity was measured by calculating their total relative value units per hour (RVUs/hr) during the nine-month study interval. The authors compared the total RVUs/hr for each attending physician to the medians of their teaching evaluation scores at each ED using a Spearman rank correlation test. Results: Seventy of 92 students returned surveys, evaluating 580 shifts taught by 53 EM attending physicians. Each attending physician received an average of 11 evaluations (median score, 5 of 6) and generated a mean of 5.68 RVUs/hr during the study period. The correlation between evaluation median scores and RVUs/hr was ,0.08 (p = 0.44). Conclusions: The authors found no statistically significant relationship between clinical productivity and teaching evaluations. While many EM attending physicians perceive patient care responsibilities to be too time consuming to allow them to be good teachers, the authors found that a subset of our more productive attending physicians are also highly rated teachers. Determining what characteristics distinguish faculty who are both clinically productive and highly rated teachers should help drive objectives for faculty development programs. [source] Availability of Rapid Human Immunodeficiency Virus Testing in Academic Emergency DepartmentsACADEMIC EMERGENCY MEDICINE, Issue 2 2008Peter D. Ehrenkranz MD Abstract Objectives:, The Centers for Disease Control and Prevention (CDC) recommends routine human immunodeficiency virus (HIV) screening of emergency department (ED) patients aged 13 to 64 years. The study objectives were to determine the accessibility of rapid HIV testing in academic EDs, to identify factors that influence an ED's adoption of testing, and to describe current HIV testing practices. Methods:, Online surveys were sent to EDs affiliated with emergency medicine (EM) residency programs (n = 128), excluding federal hospitals and facilities in U.S. territories. Eighty percent (n = 102) responded. Most e-mail recipients (n = 121) were Emergency Medicine Network (EMNet) investigators; remaining contacts were obtained from residency-related Web sites. Results:, Most academic EDs (n = 58; 57%; 95% confidence interval (CI) = 47% to 66%) offer rapid HIV testing. Among this group, 26 (45%) allow providers to order tests without restrictions. Of the other 32 EDs, 100% have policies allowing for rapid HIV testing following occupational exposures, but less than 10% have guidelines for testing in other clinical situations. Forty-seven percent expect to routinely offer HIV testing in the next 2 to 3 years. Only 59% of the EDs that offered rapid tests in any situation could link an HIV-positive patient to subspecialty care. The facility characteristic most important to availability of rapid HIV testing was the presence of on-site HIV counselors. Conclusions:, Most academic EDs now offer rapid HIV testing (57%), but few use it in situations other than occupational exposure. Less than half of academic EDs expect to implement CDC guidelines regarding routine screening within the next few years. The authors identified facility characteristics (e.g., counseling, ability to refer) that may influence adoption of rapid HIV testing. [source] Blood Cultures Do Not Change Management in Hospitalized Patients with Community-acquired PneumoniaACADEMIC EMERGENCY MEDICINE, Issue 7 2006Prasanthi Ramanujam MD Objectives: To determine if blood cultures identify organisms that are not appropriately treated with initial empiric antibiotics in hospitalized patients with community-acquired pneumonia, and to calculate the costs of blood cultures and cost savings realized by changing to narrower-spectrum antibiotics based on the results. Methods: This was a retrospective observational study conducted in an urban academic emergency department (ED). Patients with an ED and final diagnosis of community-acquired pneumonia admitted between January 1, 2001, and August 30, 2003, were eligible when the results of at least one set of blood cultures obtained in the ED were available. Exclusion criteria included documented human immunodeficiency virus infection, immunosuppressive illness, chronic renal failure, chronic corticosteroid therapy, documented hospitalization within seven days before ED visit, transfer from another hospital, nursing home residency, and suspected aspiration pneumonia. The cost of blood cultures in all patients was calculated. The cost of the antibiotic regimens administered was compared with narrower-spectrum and less expensive alternatives based on the results. Results: A total of 480 patients were eligible, and 191 were excluded. Thirteen (4.5%) of the 289 enrolled patients had true bacteremia; the organisms isolated were sensitive to the empiric antibiotics initially administered in all 13 cases (100%; 95% confidence interval = 75% to 100%). Streptococcus pneumoniae and Haemophilus influenzae were isolated in 11 and two patients, respectively. The potential savings of changing the antibiotic regimens to narrower-spectrum alternatives was only 170. Conclusions: Appropriate empiric antibiotics were administered in all bacteremic patients. Antibiotic regimens were rarely changed based on blood culture results, and the potential savings from changes were minimal. [source] Medical Error Identification, Disclosure, and Reporting: Do Emergency Medicine Provider Groups Differ?ACADEMIC EMERGENCY MEDICINE, Issue 4 2006Cherri Hobgood MD Abstract Objectives: To determine if the three types of emergency medicine providers,physicians, nurses, and out-of-hospital providers (emergency medical technicians [EMTs]),differ in their identification, disclosure, and reporting of medical error. Methods: A convenience sample of providers in an academic emergency department evaluated ten case vignettes that represented two error types (medication and cognitive) and three severity levels. For each vignette, providers were asked the following: 1) Is this an error? 2) Would you tell the patient? 3) Would you report this to a hospital committee? To assess differences in identification, disclosure, and reporting by provider type, error type, and error severity, the authors constructed three-way tables with the nonparametric Somers' D clustered on participant. To assess the contribution of disclosure instruction and environmental variables, fixed-effects regression stratified by provider type was used. Results: Of the 116 providers who were eligible, 103 (40 physicians, 26 nurses, and 35 EMTs) had complete data. Physicians were more likely to classify an event as an error (78%) than nurses (71%; p = 0.04) or EMTs (68%; p < 0.01). Nurses were less likely to disclose an error to the patient (59%) than physicians (71%; p = 0.04). Physicians were the least likely to report the error (54%) compared with nurses (68%; p = 0.02) or EMTs (78%; p < 0.01). For all provider and error types, identification, disclosure, and reporting increased with increasing severity. Conclusions: Improving patient safety hinges on the ability of health care providers to accurately identify, disclose, and report medical errors. Interventions must account for differences in error identification, disclosure, and reporting by provider type.

[source] The use of therapeutic plasmapheresis in the treatment of poisoned and snake bite victims: An academic emergency department's experiencesJOURNAL OF CLINICAL APHERESIS, Issue 4 2006Cuma Yildirim Abstract The objective of this study is to describe the clinical status, procedural interventions, and outcomes of critically ill patients with poisoning and snake bite injuries presenting to a tertiary-care emergency department for treatment with therapeutic plasmapheresis. Records of 20 patients who presented to our academic emergency department over a 2-year period and who underwent plasmapheresis for poisoning or snake bite were retrospectively reviewed. Plasmapheresis was performed using centrifugation technology via an intravenous antecubital venous or subclavian vein catheter access. Human albumin or fresh frozen plasma were used as replacement fluids. Data extracted from the patient record included demographic data, clinical status, and outcome measures. Sixteen patients underwent plasmapheresis because of toxicity from snake bite. Three patients were treated for drug poisoning (phenytoin, theophylline, bipyridene HCl) and one patient for mushroom poisoning. Haematologic parameters such as platelet count, PT, and INR resolved rapidly in victims of snake bite injuries after treatment with plasmapheresis. Loss of limbs did not occur in these cases. Seven patients required admission to the intensive care unit. One patient with mushroom poisoning died. Mean length of hospital stay was 14.3 days (range 3,28 days) for all cases. Plasmapheresis was a clinically effective and safe approach in the treatment of snake bite envenomation and other drug poisoning victims especially in the management of hematologic problems and in limb preservation/salvage strategies. In addition to established conventional therapies, emergency physicians should consider plasmapheresis among the therapeutic options in treatment strategies for selected toxicologic emergencies. J.

Resnick MD Abstract Objectives:, The most effective technique for ultrasound-guided peripheral intravenous access (USGPIVA) is unknown. In the traditional short-axis technique (locate, align, puncture [LAP]), the target vessel is aligned in short axis with the center of the transducer. The needle is then directed toward the target under real-time ultrasound (US) guidance. Locate, align, mark, puncture (LAMP) requires the extra step of marking the skin at two points over the path of the vein and proceeding with direct visualization as in LAP. The difference in success between these two techniques was compared among variably experienced emergency physician and emergency nurse operators. Methods:, Subjects in an urban academic emergency department (ED) were randomized to obtain intravenous (IV) access using either LAP or LAMP after two failed blind attempts. Primary outcomes were success of the procedure and time to complete the procedure in variably experienced operators. Results:, A total of 101 patients were enrolled. There was no difference in success between LAP and LAMP, even among the least experienced operators. Of successful attempts, LAMP took longer than LAP (median 4 minutes, interquartile range [IQR] 4,10.5 vs. median 2.9 minutes, IQR 1.6,7; p = 0.004). Only the most experienced operators were associated with higher levels of success (first attempt odds ratio [OR] 6.64; 95% confidence interval [CI] = 2 to 22). Overall success with up to two attempts was 73%. Complications included a 2.8% arterial puncture rate and 12% infiltration rate. Conclusions:, LAMP did not improve success of USGPIVA in variably experienced operators. Experience was associated with higher rates of success for USGPIVA. [source] Establishing an ED HIV Screening Program: Lessons from the Front LinesACADEMIC EMERGENCY MEDICINE, Issue 7 2007Jeremy Brown MD In September 2006, the Centers for Disease Control and Prevention released its revised recommendations for human immunodeficiency virus (HIV) testing. Prominent among these were the recommendations that emergency departments should perform routine screening for HIV infection. This report outlines the steps needed to set up an emergency department,based HIV screening program based on these guidelines. It contains the lessons that were learned when such a program was initiated at an academic emergency department. Consideration of these steps will help streamline the establishment of the program, but there should be careful consideration of the program's costs and sustainability before embarking on the process. [source] Witnessing Intimate Partner Violence as a Child Does Not Increase the Likelihood of Becoming an Adult Intimate Partner Violence VictimACADEMIC EMERGENCY MEDICINE, Issue 5 2007Amy A. Ernst MD ObjectivesTo determine whether adults who witnessed intimate partner violence (IPV) as children would have an increased rate of being victims of ongoing IPV, as measured by the Ongoing Violence Assessment Tool (OVAT), compared with adult controls who did not witness IPV as children. The authors also sought to determine whether there were differences in demographics in these two groups. MethodsThis was a cross sectional cohort study of patients presenting to a high-volume academic emergency department. Emergency department patients presenting from November 16, 2005, to January 5, 2006, during 46 randomized four-hour shifts were included. A confidential computer touch-screen data entry program was used for collecting demographic data, including witnessing IPV as a child and the OVAT. Main outcome measures were witnessing IPV as a child, ongoing IPV, and associated demographics. Assuming a prevalence of IPV of 20% and a clinically significant difference of 20% between adults who witnessed IPV as children and adult controls who did not witness IPV as children, the study was powered at 80%, with 215 subjects included. ResultsA total of 280 subjects were entered; 256 had complete data sets. Forty-nine percent of subjects were male, 45% were Hispanic, 72 (28%) were adults who witnessed IPV as children, and 184 (72%) were adult controls who did not witness IPV as children. Sixty-three (23.5%) were positive for ongoing IPV. There was no correlation of adults who witnessed IPV as children with the presence of ongoing IPV, as determined by univariate and bivariate analysis. Twenty-three of 72 (32%) of the adults who witnessed IPV as children, and 39 of 184 (21%) of the adult controls who did not witness IPV as children, were positive for IPV (difference, 11%; 95% confidence interval [CI] =,2% to 23%). Significant correlations with having witnessed IPV as a child included age younger than 40 years (odds ratio [OR], 4.2; 95% CI = 1.7 to 9.1), income less than 20,000/year (OR, 5.1; 95% CI = 1.6 to 12.5), and abuse as a child (OR, 9.1; 95% CI = 4.2 to 19.6). Other demographics were not significantly correlated with having witnessed IPV as a child. ConclusionsAdults who witnessed IPV as children were more likely to have a lower income, be younger, and have been abused as a child, but not more likely to be positive for ongoing IPV, when compared with patients who had not witnessed IPV. [source] Characterizing Waiting Room Time, Treatment Time, and Boarding Time in the Emergency Department Using Quantile RegressionACADEMIC EMERGENCY MEDICINE, Issue 8 2010Ru Ding MS ACADEMIC EMERGENCY MEDICINE 2010; 17:813,823 © 2010 by the Society for Academic Emergency Medicine Abstract Objectives:, The objective was to characterize service completion times by patient, clinical, temporal, and crowding factors for different phases of emergency care using quantile regression (QR). Methods:, A retrospective cohort study was conducted on 1-year visit data from four academic emergency departments (EDs; N = 48,896,58,316). From each ED's clinical information system, the authors extracted electronic service information (date and time of registration; bed placement, initial contact with physician, disposition decision, ED discharge, and disposition status; inpatient medicine bed occupancy rate); patient demographics (age, sex, insurance status, and mode of arrival); and clinical characteristics (acuity level and chief complaint) and then used the service information to calculate patients' waiting room time, treatment time, and boarding time, as well as the ED occupancy rate. The 10th, 50th, and 90th percentiles of each phase of care were estimated as a function of patient, clinical, temporal, and crowding factors using multivariate QR. Accuracy of models was assessed by comparing observed and predicted service completion times and the proportion of observations that fell below the predicted 10th, 50th, and 90th percentiles. Results:, At the 90th percentile, patients experienced long waiting room times (105,222 minutes), treatment times (393,616 minutes), and boarding times (381,1,228 minutes) across the EDs. We observed a strong interaction effect between acuity level and temporal factors (i.e., time of day and day of week) on waiting room time at all four sites. Acuity level 3 patients waited the longest across the four sites, and their waiting room times were most influenced by temporal factors compared to other acuity level patients. Acuity level and chief complaint were important predictors of all phases of care, and there was a significant interaction effect between acuity and chief complaint. Patients with a psychiatric problem experienced the longest treatment times, regardless of acuity level. Patients who presented with an injury did not wait as long for an ED or inpatient bed. Temporal factors were strong predictors of service completion time, particularly waiting room time. Mode of arrival was the only patient characteristic that substantially affected waiting room time and treatment time. Patients who arrived by ambulance had shorter wait times but longer treatment times compared to those who did not arrive by ambulance. There was close agreement between observed and predicted service completion times at the 10th, 50th, and 90th percentile distributions across the four EDs. Conclusions:, Service completion times varied significantly across the four academic EDs. QR proved to be a useful method for estimating the service completion experience of not only typical ED patients, but also the experience of those who waited much shorter or longer. Building accurate models of ED service completion times is a critical first step needed to identify barriers to patient flow, begin the process of reengineering the system to reduce variability, and improve the timeliness of care provided. [source] Emergency Department Operational Changes in Response to Pay-for-performance and Antibiotic Timing in PneumoniaACADEMIC EMERGENCY MEDICINE, Issue 6 2007Jesse M. Pines MD Background:The percentage of adult patients admitted with pneumonia who receive antibiotics within four hours of hospital arrival is publicly reported as a quality and pay-for-performance measure by the Department of Health and Human Services and is called PN-5b. Objectives:To determine attitudes among physician leaders at emergency medicine training programs toward using PN-5b as a quality measure for pay for performance, and to determine what operational changes academic emergency departments (EDs) have made to ensure early antibiotic administration for patients with pneumonia. Methods:The authors administered an online questionnaire to 129 chairpersons and medical directors of 135 academic ED training programs in the United States on attitudes toward performance measurement in pneumonia and changes that academic EDs have made in response to PN-5b; one response was sought from each institution. Respondents were identified through the Society for Academic Emergency Medicine Web site and e-mailed five times to maximize survey participation. Results:Ninety chairpersons and medical directors (70%) completed the survey; 47% were medical directors, 51% were chairpersons, and 2% were medical directors and chairpersons. Forty-five (50%) did not agree that PN-5b was an accurate quality measure, and 61 (69%) did not agree that pay for performance targeting this measure would lead to improved pneumonia care. The most common strategy to address PN-5b was to provide information to providers on the importance of early treatment with antibiotics (n = 63; 70%). For patients with suspected pneumonia, 46 (51%) automate chest radiograph (CXR) ordering at triage, 37 (41%) prioritize patients with suspected pneumonia, and 33 (37%) administer antibiotics before obtaining CXR results. Overall ED changes include improved turnaround time for CXR (n= 33; 37%), prioritized CXRs over other radiographs (n= 13; 14%), and improved inpatient bed availability (n= 12; 13%). Of 13 strategies identified to improve PN-5b, the median number that programs have implemented is five (interquartile range, 5,7). All sites reported engaging in at least three operational changes to address PN-5b. Conclusions:All EDs in this study have addressed early antibiotic administration with multiple operational changes despite mixed sentiment that these changes will improve care. Future research is needed to measure the impact of pay-for-performance initiatives. [source] | ||||||||||
