Jessica Castner, PhD, RN, CEN Assistant Professor University at Buffalo, New YorkMedicalResearch.com Interview with: Jessica Castner, PhD, RN, CEN Assistant Professor University at Buffalo, New York Medical Research: What is the background for this study? Dr. Castner: There are groups of people more likely to visit the emergency department (ED) frequently.  One of these groups are people insured by Medicaid, the insurance for those with low incomes.  By finding what factors increase the risk for frequent emergency department use, healthcare leaders can target interventions to design a more effective and accessible healthcare delivery system.  With approximately 12 million ED visits each year related to behavioral health issues, we wanted to investigate how smoking, substance abuse and psychiatric diagnoses increased the risk for repeat ED use for adults insured by Medicaid. There are many problems associated with frequent emergency department use, including less than ideal continuity of care, crowding, and cost. Every year, there are over 136 million visits to United States EDs, and 12 million are linked to some sort of behavioral health issue.  Unlike primary care, the patient is not likely to see a healthcare provider in the emergency department who knows them or one who may not have access to their complete and up-to-date records.  The patient might get conflicting guidance or have tests ordered that duplicate tests recently done in other settings. Frequent emergency department visitors also contribute to crowded EDs, where demand outstrips capacity. Studies have shown an association with increased morbidity and mortality for patients treated in the ED during these times of crowding. Medical Research: What are the main findings? Dr. Castner: The main findings of our study include helping to dispel the myth of “inappropriate emergency department use.”  Our research analyzed the 2009 Medicaid claims for Erie and Niagara County. Our findings indicate that there is a positive relationship between outpatient visits and frequent emergency department use.  In other words, people who are sicker and have more complex illnesses use all services more – both the emergency department and their outpatient care provider.  In addition, we found that smoking, substance abuse, and psychiatric diagnoses all substantially increased the odds of frequent emergency department use – or ED bouncebacks.  The most surprising finding was that healthy individuals were four times more likely to be frequent ED users if they smoked.

Michael B. Weinstock, MD Professor of Emergency Medicine, Adjunct Department of Emergency Medicine, The Ohio State University College of Medicine Emergency Department Chairman and Director of Medical Education, Mt. Carmel St. Ann's Dept. of Emergency Medicine Columbus, OhioMedicalResearch.com Interview with: Michael B. Weinstock, MD Professor of Emergency Medicine, Adjunct Department of Emergency Medicine, The Ohio State University College of Medicine Emergency Department Chairman and Director of Medical Education, Mt. Carmel St. Ann's Dept. of Emergency Medicine Columbus, Ohio Medical Research: What is the background for this study? Response: Patients with potential cardiac ischemia are often admitted to the hospital even after a negative evaluation in the emergency department due to concern about missed MI, unstable angina, or potential for cardiac arrhythmia. Medical Research: What are the main findings? Response: Our study was different than previous studies and clinical decision rules; instead of looking at a 30 day marker, which is important to the cardiologist, ours looked at the risk of a Clinically Relevant Adverse Cardiac Event (CRACE) occurring during hospitalization. These events included inpatient STEMI, life-threatening arrhythmia, cardiac or respiratory arrest, or death. The study found only 4 of these events out of 7266 patients studied and of the 4, two were possibly iatrogenic, suggesting that after a negative ED evaluation (including 2 negative serial cardiac enzyme tests, non-ischemic and interpretable ECG, and nonconcerning vital signs) a patient can be safely sent home for an expedited cardiac outpatient evaluation.

MedicalResearch.com Interview with: Joanne Brady, PhD candidate Department of Anesthesiology, College of Physicians and Surgeons Department of Epidemiology, Mailman School of Public Health Columbia University, New York, NY Medical Research: What is the background for this study? What are the main findings? Response: Prescription drug overdose is a major public health problem in the United States. Prescription drug overdose mortality has increased dramatically over the past twenty five years. Frequent emergency department utilization may be a marker for risk of prescription drug overdose death. The current study assessed how frequency of emergency department visits in the past year related to risk of subsequent prescription drug overdose death. In a cohort of patients visiting the emergency department, patients with four or more visits to the emergency department in the past year were at substantially higher risk for prescription drug overdose death than patients who visited the emergency department one or fewer times. As the number of visits to the emergency department increased from 0 - 1 to 4 or more for any reason the risk of dying from prescription drug overdose also increased. (more…)

dr-brian-roweMedicalResearch.com Interview with: Dr. Brian Rowe, MD, MSc, CCFP(EM), FCCP Professor, Department of Emergency Medicine University of Alberta, Edmonton, Alberta, Canada MedicalResearch: What is the background for this study? Dr. Rowe: Frequent users are also called “familiar faces” or “heavy users” and they represent an important sub-group of patients in the emergency setting, with often complex needs that contribute to overcrowding and excess health care costs. The evidence suggests that frequent users account for up to one in 12 patients seeking emergency care, and for around one in four of all visits. MedicalResearch: What are the main findings? Dr. Rowe: Frequent users of emergency department care are more than twice as likely to die, be admitted to hospital, or require other outpatient treatment as infrequent users, concludes an analysis of the available evidence, published in Emergency Medicine Journal. These conclusions are based on a thorough search of seven electronic databases of relevant research relating to the frequency and outcomes of emergency department use by adults. Out of a total of more than 4000 potential studies, 31 relevant research reports published between 1990 and 2013 were included in the final analysis. Frequent users were variably defined as visiting emergency care departments from four or more times up to 20 times a year. Among the seven studies looking at deaths, the analysis showed that frequent attenders at emergency care departments were more than twice as likely to die as those who rarely sought emergency care. Most of the studies included hospital admission as an outcome, and these showed that frequent users were around 2.5 times as likely to be admitted as infrequent users. Ten studies looked at use of other hospital outpatient care, and these showed that frequent users were more than 2.5 times as likely to require at least one outpatient clinic after their visit to the emergency care department.

Karoline Mortensen, Ph.D. Assistant Professor Department of Health Services Administration University of Maryland College Park, MDMedicalResearch.com Interview with: Karoline Mortensen, Ph.D. Assistant Professor Department of Health Services Administration University of Maryland College Park, MD Medical Research: What is the background for this study? Dr. Mortensen: For twenty years, use of hospital emergency departments has been on the rise in the United States, particularly among low-income patients who face barriers to accessing health care outside of hospitals including not having an identifiable primary health care provider. Almost half of emergency room visits are considered “avoidable.” The Emergency Department-Primary Care Connect Initiative of the Primary Care Coalition, which ran from 2009 through 2011, linked low-income uninsured and Medicaid patients to safety-net health clinics. Medical Research: What are the main findings? Dr. Mortensen: “Our study found that uninsured patients with chronic health issues – such as those suffering from hypertension, diabetes, asthma, COPD, congestive heart failure, depression or anxiety – relied less on the emergency department after they were linked to a local health clinic for ongoing care,” says Dr. Karoline Mortensen, assistant professor of health services administration at the University of Maryland School of Public Health and senior researcher. “Connecting patients to primary care and expanding the availability of these safety-net clinics could reduce emergency department visits and provide better continuity of care for vulnerable populations.” (more…)

Justin A. Ezekowitz, MBBCh MScAssociate Professor, University of Alberta Co-Director, Canadian VIGOUR Centre Director, Heart Function Clinic Cardiologist, Mazankowski Alberta Heart InstiMedicalResearch.com Interview with: Justin A. Ezekowitz, MBBCh MSc Associate Professor, University of Alberta Co-Director, Canadian VIGOUR Centre Director, Heart Function Clinic Cardiologist, Mazankowski Alberta Heart Institute Medical Research: What is the background for this study? Dr. Ezekowitz: Heart Failure is a prevalent health issue that carries high morbidity and mortality. Most epidemiologic research derives information from hospital discharge abstracts, but emergency department visits are another source of information. Many have assumed this code is accurate in the emergency department but uncertainty remains. In our study, we assessed patients at their presentation to Emergency Department, which is usually the first medical contact for acutely ill patients with heart failure. The objective of our study was to compare administrative codes for acute heart failure (I50.x) in the emergency department against a gold standard of clinician adjudication. Medical Research: What are the main findings? Dr. Ezekowitz: Emergency department administrative data is highly correlated with a clinician adjudicated diagnosis. The positive predictive value of acute heart failure as the main diagnosis was 93.3% when compared to clinician adjudication, supported by standardized scoring systems and elevated BNP. (more…)

Dr Mayris P Webber Dr.PH. MPH Bureau of Health Services Fire Department of the City of New York Brooklyn, NY Professor of Clinical Epidemiology & Population Health Montefiore Medical Center NYMedicalResearch.com Interview with: Dr Mayris P Webber Dr.PH. MPH Bureau of Health Services Fire Department of the City of New York Brooklyn, NY Professor of Clinical Epidemiology & Population Health Montefiore Medical Center NY Medical Research: What is the background for this study? What are the main findings? Dr. Webber:
  • To date, we and others have found adverse health outcomes associated with World Trade Center (WTC)  exposure among New York City’s first responders such as firefighters, police officers, and other rescue and recovery workers. We conducted the first study to concentrate on the health impact of the disaster on emergency medical service (EMS) workers.
  • In keeping with previous research on WTC’s first responders, we found that the WTC attacks adversely affected the physical and mental health of approximately 2,000 New York City Fire Department (FDNY) EMS who performed rescue and recovery work at the site.
  • We analyzed selected physical and mental health conditions that have been certified as being linked to the aftermath of the WTC attacks under the James Zadroga 9/11 Health and Compensation Act of 2010.
  • Over a 12 year period, between September 11 2001 and December 31 2013, the proportion of newly diagnosed cases of gastroesophageal reflux disease (GERD) was 12.1%; obstructive airways disease (OAD) 11.8%; rhinosinusitis 10.6%; and cancer 3.1%.
  • In their most recent mental health survey, nearly 17% of EMS workers reported symptoms consistent with depression; 7% with post-traumatic stress disorder (PTSD); and 3% with harmful alcohol use.
  • Compared with EMS workers who did not work at the WTC site, EMS workers who worked at the WTC site in the morning of 9/11 (i.e., most intensely exposed) were at greatest risk for nearly all of the health conditions analyzed.
  • For example, they were almost four times as likely to have GERD and rhinosinusitis, seven times as likely to have probable PTSD, and twice as likely to have probable depression. (We use the term probable because we used screening questionnaires instead of professional diagnoses for these mental health conditions).

Haichang Xin, PhD Department of Health Care Organization and policy School of Public Health University of Alabama at BirminghamMedicalResearch.com Interview with: Haichang Xin, PhD Department of Health Care Organization and policy School of Public Health University of Alabama at Birmingham MedicalResearch: What is the background for this study? Dr. Xin: Since high cost-sharing policies can reduce both needed care and unneeded care use, it raises the concern whether these policies are a good strategy for controlling costs among chronically ill patients, especially whether utilization and costs in emergency department (ED) service and inpatient care will increase in response. Moreover, the costs saved by reduced physician care may be offset or even exceeded by the increased ED or inpatient care expenditures, causing a total cost increase for health plans. This study was the first to examine whether high cost-sharing policies for physician care are associated with a differential impact on total care costs between chronically ill individuals and healthy individuals. Total care includes physician care, ED service and inpatient care. MedicalResearch: What are the main findings? Dr. Xin:  Chronically ill individuals’ probability of reducing any overall care costs was significantly less than healthier individuals (β= 2.18, p = 0.04), while the integrated Difference-in-difference estimator from split results in the two-part model indicated that going from low cost-sharing to high cost-sharing significantly reduced costs by $12,853.23 more for sick people than for healthy people (95% CI: -$17,582.86, -$8,123.60).

Haichang Xin, PhD Department of Health Care Organization and policy School of Public Health University of Alabama at BirminghamMedicalResearch.com Interview with: Haichang Xin, PhD Department of Health Care Organization and policy School of Public Health University of Alabama at Birmingham MedicalResearch: What is the background for this study? Dr. Xin: Research suggests that nearly half of all emergency department (ED) visits in the United States are for nonurgent conditions, leading to billions of dollars in potentially avoidable spending annually. A well-functioning primary care system has the capacity to provide timely, adequate, and effective care for patients in order to avoid nonurgent emergency department use and care costs. This study examined how deficiencies in ambulatory care were associated with nonurgent emergency department care costs nationwide, and to what extent these costs can be reduced if deficiencies in primary care systems could be improved. MedicalResearch: What are the main findings? Dr. Xin: Patient perceived poor and intermediate levels of primary care quality had higher odds of nonurgent emergency department care costs (OR=2.22, p=0.035, and OR=2.05, p=0.011, respectively) compared to high quality care, with a marginal effect (at means) of 13.0% and 11.5% higher predicted probability of nonurgent ED care costs. These ambulatory care quality deficiency related costs amounted up to $229 million for private plans (95% CI: $100 million, $358 million), $58.5 million for public plans (95% CI: $33.9 million, $83.1 million), and an overall of $379 million (95% CI: $229 million, $529 million) at the national level.

MedicalResearch.com Interview with: Anne Vorlat MD Department of Cardiology Antwerp University Hospital Department of Cardiology, Edegem, Belgium MedicalResearch: What is the background for this study? What are the main findings? Dr. Vorlat: Early diagnosis of myocardial infarction is critical for optimal treatment and prognosis of the patient. The third universal definition of myocardial infarction states that a rise and/or fall of cardiac biomarkers (preferably troponin) with at least one value above the 99th percentile of the upper reference limit is mandatory with symptoms and or ST segment changes on the ECG. Since the development of more sensitive assays for cardiac troponins, myocardial injury can be detected earlier. This has permitted to shorten the timing of the second sampling of cardiac biomarkers from 6h to 3h after the first sampling. Recent studies have tested biomarker protocols with a very short delay (e.g., 1 hour) or with a single measurement of troponin and copeptin (a marker of endogenous stress, not cardiac specific) to rule in or to rule out myocardial injury in a population with chest pain. Although these newer protocols appear to be promising, early presenters (chest pain for less than 2 hours) are underreported. The present study evaluated the usefulness of early rule-in and rule-out biomarker protocols to estimate ischemia-induced myocardial injury in an early presenter model. The “early presenter” model was tested in 107 stable patients after a short period of myocardial ischemia, induced by stenting of a significant coronary artery stenosis. High-sensitivity troponin T (hsTnT), hsTnI and copeptin were measured at the start, and 90, 180 and 360 minutes after stent implantation. We confirmed our hypothesis that short biomarkers protocols underestimate myonecrosis in early presenters. (more…)

Dr. Jean-Luc Margot PhD Professor, Department of Earth, Planetary, and Space Sciences and Department of Physics and Astronomy, University of California, Los AngelesMedicalResearch.com Interview with: Dr. Jean-Luc Margot PhD Professor, Department of Earth, Planetary, and Space Sciences and Department of Physics and Astronomy, University of California, Los Angeles Medical Research: What is the background for this study? What are the main findings? Dr. Margot: Some professionals who work in emergency rooms or maternity wards believe that the number of hospital admissions or human births is larger during the full moon than at other times.  This belief is incorrect. Analysis of the data shows conclusively that the moon does not influence the timing of hospital admissions or human births. Results of a new analysis have been published online in the journal Nursing Research.  The Nursing Research article addresses some of the methodological errors and cognitive biases that can explain the human tendency of perceiving a lunar effect where there is none.  It reviews basic standards of evidence and, using an example from the published literature, illustrates how disregarding these standards can lead to erroneous conclusions.

Michael J. Beck MD, FAAP, SSGB Department of Pediatrics Milton S. Hershey Medical Center and the Pennsylvania State University College of Medicine, Hershey, Pennsylvania MedicalResearch.com Interview with: Michael J. Beck MD, FAAP, SSGB Department of Pediatrics Milton S. Hershey Medical Center and the Pennsylvania State University College of Medicine, Hershey, Pennsylvania Medical Research: What is the background for this study? What are the main findings? Dr. Beck: Many hospitals are trying to improve patient discharge times. The benefits of this result will improve several valuable metrics within the organization’s value chain, namely improved access, reduced lost referrals, reduce emergency department boarding, to name a few. As our region’s only tertiary care children’s hospital, that serves an expanding demographics and geographic population, access to our facility is becoming both a priority and challenge. Since many hospitals and hence hospital service lines work with a fixed number of beds, serving a growing population is going to lead to or exacerbate hospital access issues and emergency department boarding. The latter of which may carry financial penalties in the future based on Joint Commission standard LD 04.03.01 (revised 2013). We sought to applying elements of Lean and constraint theory, which postulate that flow can be created by eliminating waste, and that a process can move only as fast as its scarcest resource, respectively. From a lean perspective, why should  “dischargeable” patients who were seen on AM work rounds still be occupying a valuable bed at 3 or 4PM when they were deemed safe for discharge hours earlier? Why should patients and organizations continue to tolerate this waste? Applying Lean thinking  forced our service to reconfigure, re-sequence, and re-staff rounds in a way that could better meet patients’ and our organization’s needs and requirements.  Since the discharge process output is an open bed, not having an open bed when it is needed, creates an organizational constraint. One constraint to creating an open bed, is the attending physician, ie a patient cannot be discharged until he/she is seen by the attending physician. However, another constraint is the model that one attending sees in excess of 13 patients per day (patient: provider ratio of 13:1). We hypothesized that by adding an attending  to reduce the  patient: provider ratio by 50% during predictable high volumes, we could do all of the discharge paperwork on rounds, at the time the decision to discharge is made by the attending.  By advancing discharge order entry time, we should be able to advance the time patients get discharged, create an open bed earlier in the day, and ultimately reduce lost referrals and emergency department boarding. Our service line median time of discharge order entry and time of patient discharge was compared to our own historical controls and to the same discharge behaviors of the remainder of our hospital services. The main intervention was staffing reallocation, creation of standard workflow expectations, and a discharge checklist. Finally, we also implemented a discharge huddle to occur before the day of anticipated day discharge. Over the 6 month intervention period, the median time of discharge entry decreased from 2:05PM to 10:45 AM and the median time of patient discharge decreased from 3:58PM to 2:15 PM.  The hospital  control group did not change from baseline. Our LOS went form 3.1 days to 3.0 days, and our 7, 14, and 30 day readmission rates did not increase. Emergency department boarding time was decreased by 30%, and lost referrals decreased 70% during the study period. (more…)

MedicalResearch.com Interview with: Asako Moriya Ph.D School of Public and Environmental Affairs Indiana University, Bloomington, IN Center for Financing, Access and Cost Trends Agency for Healthcare Research and Quality Rockville, MD MedicalResearch: What is the background for this study? What are the main findings? Response: Historically, young adults have had the lowest rate of insurance coverage.  They have also frequently sought non-urgent care in emergency departments (EDs). However, ED care, while appropriate for injuries and other true emergencies, is very expensive and inefficient for non-urgent care. The Affordable Care Act (ACA)’s dependent coverage provision requires health plans that offer dependent coverage to allow young adults to stay on their parents’ private health plans until age 26. This insurance expansion had a potential to improve efficiency by reducing inappropriate ED use. We used data from the Agency for Healthcare Research and Quality and found that the quarterly ED-visit rate decreased by a small, but statistically significant amount (1.6 per 1,000 population) among adults age 19-25 after the implementation of the ACA’s dependent coverage provision. The decrease was concentrated among women, weekday visits, non-urgent conditions, and conditions that could be treated in other settings. We found no effect among visits due to injury, weekend visits, and urgent conditions. The findings suggest that the ACA’s dependent coverage provision has increased the efficiency of medical care delivery by reducing non-urgent ED use. Having access to their parents’ health insurance appears to be prompting young adults to use medical care more appropriately. (more…)

MedicalResearch.com Interview with: Erin R. Schlemmer, MPH Health Care Manager / Epidemiologist Department of Clinical Epidemiology & Biostatistics Blue Cross Blue Shield of Michigan MedicalResearch: What is the background for this study? Response: Low back pain (LBP) is a common reason for emergency department (ED) visits. Usually, uncomplicated acute LBP is a benign, self-limited condition that can be managed without the need for imaging studies. However, national data have shown that a substantial proportion of ED patients with LBP receive imaging studies, and that the use of advanced imaging has increased considerably for this population in recent years. A number of groups (including specialty societies, a consortium of health plan medical directors, and an expert panel of emergency medicine physicians) have offered recommendations for the appropriate use of imaging for Low back pain. Within these guidelines, there are a number of “red flag” conditions that serve as indications for Low back pain imaging, and it is generally accepted that most patients do not require imaging to inform treatment of their Low back pain unless they have one or more red flags. Our objective was to use claims data from a large commercial insurer to describe the imaging indications and imaging status of patients presenting to the ED with Low back pain, and to describe demographic and healthcare use characteristics associated with non-indicated imaging. MedicalResearch: What are the main findings? Response: We found that over half (51.9%) of all patients presenting to the ED with low back pain had no claims-based evidence of indications for imaging. Overall, 36.5% of patients received imaging, and 10.2% received advanced imaging (CT or MRI). Among patients with imaging indications, the most common indication was trauma (71.6%), followed by cancer (24.0%). Although nearly a third of non-indicated patients received imaging, this population had a lower prevalence of imaging compared to patients with imaging indications (30.1% vs. 43.5%), and were also less likely to have prior healthcare use (such as ED visits) in the past year. Among non-indicated patients who received imaging, 26.2% received advanced imaging (CT or MRI) and 4.3% had >1 type of imaging. (more…)

Michael Wilson, MD, PhD, FAAEM Attending Physician, UCSD Department of Emergency Medicine Director, Department of Emergency Medicine Behavioral Emergencies Research (DEMBER) lab UC San Diego Health SystemMedicalResearch.com Interview with: Michael Wilson, MD, PhD, FAAEM Attending Physician, UCSD Department of Emergency Medicine Director, Department of Emergency Medicine Behavioral Emergencies Research (DEMBER) lab UC San Diego Health System MedicalResearch: What is the background for this study? What are the main findings? Dr. Wilson: Emergency departments (EDs) nationwide are crowded. Although psychiatric patients do not make up the largest proportion of repeat visitors to the emergency department, psychiatric patients stay longer in the ED than almost any other type of patient. So, it’s really important to find out things about these patients that may predict longer stays. In this study, we looked at patients on involuntary mental health holds. The reasoning is simple: patients on involuntary mental health holds aren’t free to leave the ED. So, the only thing that should really matter is how quickly an Emergency department can release them from the involuntary hold. Surprisingly, though, this wasn’t the only thing that correlated with longer stays. (more…)

Richard J. Holden, PhD Assistant Professor Department of BioHealth Informatics Indiana University School of Informatics and Computing – Indianapolis Indianapolis, IN 46202MedicalResearch.com Interview with: Richard J. Holden, PhD Assistant Professor Department of BioHealth Informatics Indiana University School of Informatics and Computing – Indianapolis Indianapolis, IN  46202 Medical Research: What was your motivation for this study? Dr. Holden: Many patients arrive in the emergency room with acute heart failure (AHF), a worsening of their chronic heart failure condition. These visits and subsequent hospital admissions and readmissions for acute heart failure represent a sizeable cost in the US healthcare system. Evidence suggests that some of these cases could be prevented if patients were better able to perform self-care activities such as monitoring their symptoms, taking medications, getting exercise, and maintaining a sodium-restricted diet. However, in community-based studies that we and others have done, patients with heart failure face a variety of barriers to optimally performing self-care. We therefore created an instrument to assess barriers to self-care, which we designed to be implemented in the emergency room. We tested the instrument with 31 patients with acute heart failure at Vanderbilt University’s adult Emergency Department. Medical Research: What are the main findings? Dr. Holden: Almost everyone who participated reported experiencing barriers to self-care. A median of 15 barriers per patient were reported. Of the 47 barriers that we tested, 34 were reported by at least one quarter of participants. The top ten most prevalent barriers included individual-level factors such as physical disability, disease knowledge, and memory deficits as well as factors related to the organization of home life, including major disruptions such as holidays. Other barriers were related to inadequate health information, low literacy, and lack of resources. Many barriers interacted with one another, for example, lack of transportation yet not wanting to rely on others. We found that the instrument could be feasibly administered within a short period following the patient’s emergency room arrival. (more…)

Ania Z. Kielar, MD, FRCPC Department of Radiology at the University of Ottawa The Ottawa Hospital, Ottawa, Ontario,CanadaMedicalResearch.com Interview with: Ania Z. Kielar, MD, FRCPC Department of Radiology at the University of Ottawa The Ottawa Hospital, Ottawa, Ontario,Canada Medical Research: What is the background for this study? What are the main findings? Dr. Kielar: One of the goals of imaging is to provide homogeneous and consistent, high-quality care for patients using available equipment.  In our hospital system, we had two separate hospitals that merged to form one teaching centre over 15 years ago.  Most processes and protocols are same between the two hospital sites as a result of having the same administration and the same University affiliation. Also,  the same residents and staff  rotate through the emergency departments and radiology departments at both hospitals.  One variable that persists is the location of the CT scanner.  At one center a space was created to place a CT scanner in the Emergency Department. At the other site, the CT scanner is in the radiology department.  For non-trauma cases, we wanted to see if the difference in distance of the scanner with respect to  the emergency department location, has a role in the time required to obtain CT scan from the time it is requested ,as well as the time to final patient disposition. We defined final patient disposition to include admission, subspecialty consultation or discharge home. Medical Research: What are the main findings? Dr. Kielar:  We found that there was a statistically significant difference in the time between requested CT and time to completion of the CT between the two hospital sites. It was faster when the CT scanner was located in the emergency department.  This was in the range of 16 minutes ,which is longer than simply the time required to walk over (and back) to the the CT scanner from the emergency department. We also found a statistically significant difference in the time of the final patient disposition.  Of note, there was no statistically significant difference noted in the time to obtain a CT scan as well as the preliminary radiology interpretation for patients with hyperacute conditions such as suspected abdominal aortic aneurysm rupture, regardless of the location of the CT scanner with respect to the ED.

Gery P. Guy Jr., PhD, MPH Health economist Division of Cancer Prevention and Control’s Epidemiology and Applied Research Branch CDCMedicalResearch.com Interview with: Gery P. Guy Jr., PhD, MPH Health economist Division of Cancer Prevention and Control’s Epidemiology and Applied Research Branch CDC Medical Research: What is the background for this study? What are the main findings? Dr. Guy: Indoor tanning exposes users to intense UV radiation and is associated with an increased risk of skin cancer. However, little is known about the more immediate adverse outcomes of indoor tanning. This study provides the first national estimates of visits to emergency departments related to indoor tanning. We examined cases from the Consumer Product Safety Commission’s National Electronic Injury Surveillance System (NEISS), a national probability sample of hospitals in the U.S. and its territories. Patient information is collected from each NEISS hospital for every emergency visit involving an injury associated with consumer products. From this sample, the total number of product-related injuries treated in hospital emergency rooms nationwide can be estimated. (more…)

Marco, MD, FACEP Professor Department of Emergency Medicine Wright State University Kettering, OH 45429 Medical Research: What is the background for this study? What are the main findings? Dr. Marco: In 2003, the Accreditation Council for Graduate Medical Education (ACGME) implemented standards on duty hours and supervision. A maximum of 80 hours of duty per week were stipulated.  The aim of these standards was to promote resident learning and patient safety.  However, evidence has not clearly demonstrated whether the 2003 requirements improved trainee well-being or patient safety.    On July 1, 2011, the ACGME implemented additional regulations on duty hours and supervision, including a 16 hour maximum shift length for PGY1 residents. The duty hours standards were implemented to ensure patient safety and provide an excellent teaching environment.  Emergency Medicine has additional duty hours requirements for emergency department rotations, including a maximum of 12 continuous scheduled hours, and a maximum 60 scheduled hours per week seeing patients in the emergency department, and no more than 72 duty hours per week. We found that among a large cohort of 4134 Emergency Medicine residents, the majority of residents stated that they are working the appropriate number of hours to practice independently at graduation.  The majority of residents believe that current duty hours regulations improve patient safety.  The majority of residents agreed that duty hour regulations are currently appropriate.

Dr. Greenberg: Capital Health Regional Medical Center in Trenton, NJ opened the first dedicated Neurologic Emergency Department in the country in January of 2011.  Dr. Veznedaroglu, our chief neurosurgeon, recognized the importance and emergent nature of patients with neurologic complaints.  He recruited dedicated Emergency Medicine Physicians, one of which is myself, who would be assigned to see patients with neurologic complaints during peak hours of 7a-6p daily seven days a week.  Having a section of the ED dedicated to identifying, triaging, and treating patients with neurologic emergencies has led to more advanced and efficient care.  Due to the initial success of the neuro ED, 5 dedicated physicians became educated and comfortable in administering IV-tPA to acute ischemic stroke patients.  This decision was made to eliminate delays associated with teleneurology or neurology consultation prior to administering thrombolytics in order to improve door-to-needle times and outcomes in acute stroke patients.  As far as we know, we are still the only dedicated Neuro ED in the country.

Dr. Jennifer Marin MD MSc Director of Emergency Ultrasound, Division of Pediatric Emergency Medicine Assistant Professor of Pediatrics and Emergency Medicine University of Pittsburgh School of MedicineMedicalResearch.com Interview with: Dr. Jennifer Marin MD MSc Director of Emergency Ultrasound Division of Pediatric Emergency Medicine Assistant Professor of Pediatrics and Emergency Medicine University of Pittsburgh School of Medicine Medical Research: What is the background for this study? What are the main findings? Dr. Marin: Overuse of diagnostic imaging in the emergency department has become a focus of concern from policy makers, patients, and physicians. There are evidence-based clinical decision rules and policy recommendations published in order to optimize the use of such imaging. However, physicians don't necessarily use these tools in their decision-making. Head computed tomography (CT) imaging for patients with minor head trauma is a common CT performed in the emergency setting. Our study sought to evaluate how often physicians adhered to the American College of Emergency Physicians (ACEP) Clinical Policy on Neuroimaging. The policy outlines which patients warrant a CT in the setting of minor head trauma based on certain factors, such as age, mechanism of injury, and signs and symptoms of head trauma. What we found is that when the policy recommends that a head CT be performed, it is obtained more than 90% of the time. However, when a head CT is not recommended, it is actually obtained in nearly half of those patients. We hope this will draw attention to decision rules and clinical policies, such as that from ACEP, and remind physicians that using these tools can assist in appropriate imaging practices. (more…)

Michael J. Ward, MD, MBA K12 Scholar Assistant Professor Vanderbilt University Department of Emergency Medicine Nashville, TN 37232MedicalResearch.com Interview with: Michael J. Ward, MD, MBA K12 Scholar Assistant Professor Vanderbilt University Department of Emergency Medicine Nashville, TN 37232 Medical Research: What is the background for this study? What are the main findings? Dr. Ward: The number of Americans living with cardiovascular disease is only expected to increase in the coming years.  However, we do not know the national effects of increased medication use and preventive efforts to stop the most serious form of a heart attack, called an ST-elevation myocardial infarction (STEMI). In particular, there are no estimates of how often this serious form of a heart attack shows up in the emergency department. Between 2006 and 2011 we found an average of 258,000 STEMIs annually in the U.S. or 8.7 per 10,000 U.S. adults per year. Interestingly, the number of STEMIs has decreased by more than 70,000 per year over this time, a 24% reduction. We found similar annual decreases across every age group and geographic region in the U.S. The decreases were most pronounced among those 85 years and older and in the Midwest. (more…)

Bentley Bobrow, MD, Medical Director Bureau of Emergency Medicine Services and Trauma System Arizona Department of Health Services, Phoenix Professor, University of ArizoneaMedicalResearch.com Interview with: Bentley Bobrow, MD, Medical Director Bureau of Emergency Medicine Services and Trauma System Arizona Department of Health Services, Phoenix Professor, University of Arizona Medical Research: What is the background for this study? What are the main findings? Dr. Bobrow: Out-of-Hospital Cardiac Arrest is a leading cause of death worldwide. There are nearly half a million EMS-assessed Out-of-Hospital Cardiac Arrest s in the United States annually. Bystander CPR (B-CPR) before arrival of EMS can double or even triple survival from OHCA. Yet it occurs in only 1/3 of cases. Telephone CPR - the provision of B-CPR with a 9-1-1 telecommunicator's instructions - is independently associated with increased rates of Bystander CPR and patient survival and requires almost no capital investment. For this reason, we believe Telephone CPR may be THE most effective and efficient way to move the needle on OHCA survival. In order to achieve this potential, however, EMS systems must adopt the latest guideline recommendations for T-CPR and continuously measure system performance. Very few systems do this. The aim of our project was to do just this at multiple 9-1-1 centers in Arizona. We implemented the guidelines and measured the impact on process metrics and patient outcomes. Our findings confirmed what we expected: a significant increase in the proportion of cases where T-CPR was performed, a significant reduction in time from call-receipt to first bystander chest compression, and, most importantly, significant increases in patient survival and survival with positive neurologic outcome.

Dr. Marc-Alexander Ohlow, MD, adjunct Professor of Medicine Cardiology Department Zentralklinik Bad Berka, GermanyMedicalResearch.com Interview with: Dr. Marc-Alexander Ohlow, MD, Adjunct Professor of Medicine Cardiology Department Zentralklinik Bad Berka, Germany MedicalResearch.com: What are the main findings of the study? Dr. Ohlow: This paper reports the finding of a retrospective study including 4.311 consecutive patients with suspected acute coronary syndrome (ACS). Out of them 272 patients with acute onset of chest pain and elevated levels of cardiac necrosis markers did not have significant (≥50% diameter stenosis) coronary artery stenosis on coronary angiography. Aim of this study was to provide further information and understanding of the clinical characteristics and outcome of patients with acute coronary syndrome without critical stenosis, and comparing those with a consecutive series of patients with ACS requiring percutaneous coronary intervention (non-ST-elevation myocardial infarction patients). Patients presenting without significant coronary stenosis, but with chest pain and elevated troponin level were younger, had less severe angina symptoms, were more likely to be women, had lower level of myocardial necrosis markers (troponin and creatine kinase), and had higher left ventricular ejection fraction compared to patients undergoing angioplasty due to significant coronary obstruction.

Anna Alassaad Pharmacist, PhD Student, Department of Medical Sciences, Uppsala University Uppsala, Sweden, Uppsala University Hospital, Uppsala, SwedenMedicalResearch.com Interview with: Anna Alassaad Pharmacist, PhD Student, Department of Medical Sciences, Uppsala University Uppsala, Sweden, Uppsala University Hospital, Uppsala, Sweden Medical Research: What is the background for this study? What are the main findings? Response: The main findings from our study are that patients with a low number of prescribed drugs benefited more from a comprehensive clinical pharmacist intervention than patients with a higher number of drugs. There was no difference in effect between the patients with higher and lower levels of inappropriate prescribing, as measured by two validated tools for inappropriate prescribing. Clinical pharmacist interventions have in several studies shown positive effects on inappropriate prescribing and clinical outcomes. Since the concomitant use of a large number of drugs is associated with an increased risk of adverse drug events, it is often assumed that patients receiving a larger number of drugs would benefit most from interventions aiming to improve the quality of drug use. However, differences in the effects of clinical pharmacist intervention between different subgroups of patients have rarely been analyzed. We have, in a randomized controlled trial, previously demonstrated that a clinical pharmacist intervention at an acute internal medicine hospital ward reduces emergency department visits by 47%, revisits to hospital by 16%, and drug-related readmissions by 80% for patients aged 80 years or older. We aimed to investigate whether there was any difference in treatment effect of the clinical pharmacist interventions on number of subsequent revisits to the emergency department between the patients with less than five drugs and those with five or more drugs on admission to hospital. We also explored whether the effect of the intervention was consistent for patients with a high or low level of inappropriate prescribing. (more…)

Daniel A. Waxman, MD, PhD Department of Emergency Medicine David Geffen School of Medicine University of California, Los Angeles RAND Corporation Santa Monica, CaliforniaMedicalResearch.com Interview with: Daniel A. Waxman, MD, PhD Department of Emergency Medicine David Geffen School of Medicine University of California, Los Angeles RAND Corporation Santa Monica, California Medical Research: What are the main findings of the study? Dr. Waxman: About 10 years ago, three states (Texas, Georgia, and South Carolina) passed laws which made it much harder for doctors to be sued for malpractice related to emergency room care.   The goal of our research was to determine whether the lower risk of being sued translated into less costly care by emergency physicians.  To figure this out, we looked at the billing records of nearly 4 million Medicare patients and compared care before and after the laws took effect, and between states that passed reform and neighboring states that didn’t change their laws.   We found that these substantial legal protections didn’t cause ER doctors to admit fewer patients to the hospital, to order fewer CT or MRI scans, or to spend less for the overall ER visit.

Dr. Caroline E Stephens PhD Department of Community Health Systems University of California, San FranciscoMedicalResearch.com Interview with: Dr. Caroline E Stephens PhD Department of Community Health Systems University of California, San Francisco Medical Research: What are the main findings of the study? Dr. Stephens: In our national random sample of nursing home residents, we found that mild cognitive impairment (CI) predicted higher rates of ED visits compared to no CI, but interestingly, ED visit rates decreased as severity of cognitive impairment increased.  However, after nursing home residents were evaluated in the ED, severity of CI was not significantly associated with higher odds of hospitalization. Another important finding was that the proportion of nursing home residents using feeding tubes more than tripled in advanced or end-stage dementia, from 9.9% to 33.8%.  Moreover, tube-fed nursing home residents had 73% higher rates of total ED visits, but once evaluated in the ED, they were no more likely to be hospitalized than those without feeding tubes.  This finding is particularly striking given the numerous existing studies that have questioned the utility and appropriateness of using feeding tubes in people with advanced dementia.

MedicalResearch.com Interview with: Lindsay Cohen MD Department of Emergency Medicine University of British Columbia Medical Research: What are the main findings of the study? Dr. Cohen: In our systematic review of the literature, we sought to synthesize the available evidence on the effect of ketamine on clinical outcomes as compared to other sedative agents in intubated patients. Our outcomes of interest included intracranial and cerebral perfusion pressures, neurologic outcomes, ICU length of stay, and mortality. We included only randomized controlled trials and prospective controlled studies, and identified a total of ten studies that met our inclusion criteria. Due to the lack of homogeneity in the studies, data was analyzed in a qualitative manner. None of the studies reported significant differences between ketamine and other sedative agents for any of our outcomes of interest. (more…)

Wendy Macias Konstantopoulos, MD, MPH Department of Emergency Medicine Division of Global Health & Human Rights Massachusetts General Hospital Harvard Medical SchoolMedicalResearch.com Interview with: Wendy Macias Konstantopoulos, MD, MPH Department of Emergency Medicine Division of Global Health & Human Rights Massachusetts General Hospital Harvard Medical School Medical Research: What are the main findings of the study? Dr. Macias-Konstantopoulos: Nearly two-thirds (64%) of 3240 emergency department (ED) patients who endorsed using drugs in the last 30 days, met criteria for problematic drug use (DAST-10 score ≥3). Of patients who identified their primary drug of use as being a substance other than cannabis, approximately 91% met criteria for problematic drug use, including nearly 94% of those using illicit drugs and 76% of those using pharmaceuticals. Compared to those who used cannabis primarily, primary non-cannabis users had an almost 15 times higher odds of meeting criteria for problematic drug use. Finally, we know from previous studies that drug-using individuals are more likely to access medical care through the ED and more likely to require hospitalization than their non-drug using counterparts. Our study found that drug-using ED patients who met criteria for problematic drug use tended to have ED triage levels associated with higher levels of severity or resource utilization when compared to drug-using ED patients who did not meet criteria for a drug problem.
