Sepsis Bundles and Compliance With Clinical Guidelines

Realizing the vast medical benefits of validated protocols, recommendations and practice guidelines requires acceptance and implementation by frontline care providers. Knowledge translation is the science of accelerating the transfer of knowledge to practice by understanding and creatively addressing the barriers that prevent adoption of new professional standards. In an attempt to improve patient care and reduce mortality, the Surviving Sepsis Campaign and The Institute for Healthcare Improvement created the resuscitation and management bundles for patients with severe sepsis and septic shock. These bundles have been accepted as best practice by many clinicians since multiple clinical trials have produced similar positive results when they were implemented. However, transferring these research outcomes-based guidelines to the clinical practice arena has been associated with poor compliance due to important barriers to implementation. Delays in the adoption of sepsis bundles are not surprising since the time from validation to implementation of a new clinical practice is typically 17 years. Using sepsis bundles as a model, this article explores why guidelines are important, examines physician adherence to protocols, and reviews the literature on strategies to improve clinical compliance and enhance knowledge translation.

Syndromic Surveillance for Influenza in the Emergency Department–A Systematic Review

The science of surveillance is rapidly evolving due to changes in public health information and preparedness as national security issues, new information technologies and health reform. As the Emergency Department has become a much more utilized venue for acute care, it has also become a more attractive data source for disease surveillance. In recent years, influenza surveillance from the Emergency Department has increased in scope and breadth and has resulted in innovative and increasingly accepted methods of surveillance for influenza and influenza-like-illness (ILI). We undertook a systematic review of published Emergency Department-based influenza and ILI syndromic surveillance systems. A PubMed search using the keywords “syndromic”, “surveillance”, “influenza” and “emergency” was performed. Manuscripts were included in the analysis if they described (1) data from an Emergency Department (2) surveillance of influenza or ILI and (3) syndromic or clinical data. Meeting abstracts were excluded. The references of included manuscripts were examined for additional studies. A total of 38 manuscripts met the inclusion criteria, describing 24 discrete syndromic surveillance systems. Emergency Department-based influenza syndromic surveillance has been described worldwide. A wide variety of clinical data was used for surveillance, including chief complaint/presentation, preliminary or discharge diagnosis, free text analysis of the entire medical record, Google flu trends, calls to teletriage and help lines, ambulance dispatch calls, case reports of H1N1 in the media, markers of ED crowding, admission and Left Without Being Seen rates. Syndromes used to capture influenza rates were nearly always related to ILI (i.e. fever +/− a respiratory or constitutional complaint), however, other syndromes used for surveillance included fever alone, “respiratory complaint” and seizure. Two very large surveillance networks, the North American DiSTRIBuTE network and the European Triple S system have collected large-scale Emergency Department-based influenza and ILI syndromic surveillance data. Syndromic surveillance for influenza and ILI from the Emergency Department is becoming more prevalent as a measure of yearly influenza outbreaks.

Would earlier microbe identification alter antibiotic therapy in bacteremic emergency department patients

BACKGROUND Although debate exists about the treatment of sepsis, few disagree about the benefits of early, appropriately targeted antibiotic administration. STUDY OBJECTIVES To determine the appropriateness of empiric antimicrobial therapy and the extent to which therapy would be altered if the causative organism for sepsis was known at the time of administration. METHODS This was a retrospective cohort study, conducted in an academic Emergency Department (ED), on consecutive positive blood cultures between November 1, 2008 and February 1, 2009. Blood cultures and the appropriateness of administered antimicrobial therapy were evaluated. Therapy choices were categorized based on whether or not a physician, complying with antimicrobial guidelines, would have made changes to empiric antibiotic therapy had the causative organism initially been known. RESULTS There were 90 positive blood cultures obtained from 84 patients. Of these, 21.1% (n=19) were considered contaminants. The final categorization of empiric antibiotics given in the ED for the remaining blood culture results were: 1) therapy would be changed to narrower-spectrum antibiotics (n=34, 55.7%); 2) therapy would be changed because the organism was not covered (n=13, 21.3%); and 3) therapy would remain the same (n=14, 23.0%). There was 90.2% inter-rater agreement for these classifications (p<0.0001), with a kappa of 0.84. Polymerase chain reaction analysis had a statistically significant advantage (p<0.0001) over Infectious Disease Society of America protocols in facilitating accurate antimicrobial therapies. CONCLUSION This study confirms the need for more rapid and accurate laboratory methods for bloodstream pathogen identification.

Analysis of Automated External Defibrillator Device Failures Reported to the Food and Drug Administration

STUDY OBJECTIVE Automated external defibrillators are essential for treatment of cardiac arrest by lay rescuers and must determine when to shock and if they are functioning correctly. We seek to characterize automated external defibrillator failures reported to the Food and Drug Administration (FDA) and whether battery failures are properly detected by automated external defibrillators. METHODS FDA adverse event reports are catalogued in the Manufacturer and User Device Experience (MAUDE) database. We developed and internally validated an instrument for analyzing MAUDE data, reviewing all reports in which a fatality occurred. Two trained reviewers independently analyzed each report, and a third resolved discrepancies or passed them to a committee for resolution. RESULTS One thousand two hundred eighty-four adverse events were reported between June 1993 and October 2008, of which 1,150 were failed defibrillation attempts. Thirty-seven automated external defibrillators never powered on, 252 failed to complete rhythm analysis, and 524 failed to deliver a recommended shock. In 149 cases, the operator disagreed with the devices rhythm analysis. In 54 cases, the defibrillator stated the batteries were low and in 110 other instances powered off unexpectedly. Interrater agreement between reviewers 1 and 2 ranged by question from 69.0% to 98.6% and for most likely cause was 55.9%. Agreement was obtained for 93.7% to 99.6% of questions by the third reviewer. Remaining discrepancies were resolved by the arbitration committee. CONCLUSION MAUDE information is often incomplete and frequently no corroborating data are available. Some conditions not detected by automated external defibrillators during self-test cause units to power off unexpectedly, causing defibrillation delays. Backup units frequently provide shocks to patients.

Implementation of the Introductory Clinician Development Series: an optional boot camp for Emergency Medicine interns

Background The transition from medical student to first-year intern can be challenging. The stress of increased responsibilities, the gap between performance expectations and varying levels of clinical skills, and the need to adapt to a new institutional space and culture can make this transition overwhelming. Orientation programs intend to help new residents prepare for their new training environment. Objective To ease our interns’ transition, we piloted a novel clinical primer course. We believe this course will provide an introduction to basic clinical knowledge and procedures, without affecting time allotted for mandatory orientation activities, and will help the interns feel better prepared for their clinical duties. Methods First-year Emergency Medicine residents were invited to participate in this primer course, called the Introductory Clinician Development Series (or “intern boot camp”), providing optional lecture and procedural skills instruction prior to their participation in the mandatory orientation curriculum and assumption of clinical responsibilities. Participating residents completed postcourse surveys asking for feedback on the experience. Results Survey responses indicated that the intern boot camp helped first-year residents feel more prepared for their clinical shifts in the Emergency Department. Conclusion An optional clinical introductory series can allow for maintenance of mandatory orientation activities and clinical shifts while easing the transition from medical student to clinician.

Physician Documentation of Sepsis Syndrome Is Associated with More Aggressive Treatment

Introduction Timely recognition and treatment of sepsis improves survival. The objective is to examine the association between recognition of sepsis and timeliness of treatments. Methods We identified a retrospective cohort of emergency department (ED) patients with positive blood cultures from May 2007 to January 2009, and reviewed vital signs, imaging, laboratory data, and physician/nursing charts. Patients who met systemic inflammatory response syndrome (SIRS) criteria and had evidence of infection available to the treating clinician at the time of the encounter were classified as having sepsis. Patients were dichotomized as RECOGNIZED if sepsis was explicitly articulated in the patient record or if a sepsis order set was launched, or as UNRECOGNIZED if neither of these two criteria were met. We used median regression to compare time to antibiotic administration and total volume of fluid resuscitation between groups, controlling for age, sex, and sepsis severity. Results SIRS criteria were present in 228/315 (72.4%) cases. Our record review identified sepsis syndromes in 214 (67.9%) cases of which 118 (55.1%) had sepsis, 64 (29.9%) had severe sepsis, and 32 (15.0%) had septic shock. The treating team contemplated sepsis (RECOGNIZED) in 123 (57.6%) patients. Compared to the UNRECOGNIZED group, the RECOGNIZED group had a higher use of antibiotics in the ED (91.9 vs.75.8%, p=0.002), more patients aged 60 years or older (56.9 vs. 33.0%, p=0.001), and more severe cases (septic shock: 18.7 vs. 9.9%, severe sepsis: 39.0 vs.17.6%, sepsis: 42.3 vs.72.5%; p<0.001). The median time to antibiotic (minutes) was lower in the RECOGNIZED (142) versus UNRECOGNIZED (229) group, with an adjusted median difference of −74 minutes (95% CI [−128 to −19]). The median total volume of fluid resuscitation (mL) was higher in the RECOGNIZED (1,600 mL) compared to the UNRECOGNIZED (1,000 mL) group. However, the adjusted median difference was not statistically significant: 262 mL (95% CI [ −171 to 694 mL]). Conclusion Patients whose emergency physicians articulated sepsis syndrome in their documentation or who launched the sepsis order set received antibiotics sooner and received more total volume of fluid. Age <60 and absence of fever are factors associated with lack of recognition of sepsis cases.

Analysis of the evaluative components on the Standard Letter of Recommendation (SLOR) in Emergency Medicine.

Introduction The standard letter of recommendation in emergency medicine (SLOR) was developed to standardize the evaluation of applicants, improve inter-rater reliability, and discourage grade inflation. The primary objective of this study was to describe the distribution of categorical variables on the SLOR in order to characterize scoring tendencies of writers. Methods We performed a retrospective review of all SLORs written on behalf of applicants to the three Emergency Medicine residency programs in the University of Arizona Health Network (i.e. the University Campus program, the South Campus program and the Emergency Medicine/Pediatrics combined program) in 2012. All “Qualifications for Emergency Medicine” and “Global Assessment” variables were analyzed. Results 1457 SLORs were reviewed, representing 26.7% of the total number of Electronic Residency Application Service applicants for the academic year. Letter writers were most likely to use the highest/most desirable category on “Qualifications for EM” variables (50.7%) and to use the second highest category on “Global Assessments” (43.8%). For 4-point scale variables, 91% of all responses were in one of the top two ratings. For 3-point scale variables, 94.6% were in one of the top two ratings. Overall, the lowest/least desirable ratings were used less than 2% of the time. Conclusions SLOR letter writers do not use the full spectrum of categories for each variable proportionately. Despite the attempt to discourage grade inflation, nearly all variable responses on the SLOR are in the top two categories. Writers use the lowest categories less than 2% of the time. Program Directors should consider tendencies of SLOR writers when reviewing SLORs of potential applicants to their programs.

Online research article discussion board to increase knowledge translation during emergency medicine residency

Background Many clinicians have difficulties reading current best practice journal articles on a regular basis. Discussion boards are one method of online asynchronous learning that facilitates active learning and participation. We hypothesized that an online repository of best practice articles with a discussion board would increase journal article reading by emergency medicine residents. Methods Participants answered three questions weekly on a discussion board: What question does this study address? What does this study add to our knowledge? How might this change clinical practice? A survey regarding perceived barriers to participating was then distributed. Results Most participants completed an article summary once or twice in total (23/32, 71.9%). Only three were involved most weeks (3/32, 9.4%) whereas 5/32 (15.6%) participated monthly. The most common barriers were lack of time (20/32, 62.5%), difficulty logging on (7/32, 21.9%), and forgetting (6/32, 18.8%). Conclusion Although subjects were provided weekly with an article link, email, and feedback, journal article reading frequency did not increase.

Impact and feasibility of an emergency department–based ventilator-associated pneumonia bundle for patients intubated in an academic emergency department

HighlightsVentilator‐associated pneumonia prevention is standard care in the intensive care unit, but not yet in the emergency department.Ventilator‐associated pneumonia occurs frequently in emergency department intubated patients who may remain in the emergency department for many hours.Starting ventilator‐associated pneumonia prevention in the emergency department results in decreased overall and early ventilator‐associated pneumonia for these patients.High rates of compliance with an emergency department–based ventilator‐associated pneumonia bundle can be achieved.Bundle compliance is improved with a registered nurse (RN) champion. Background: Ventilator‐associated pneumonia (VAP) has been linked to emergency department (ED) intubation and length of stay (LOS). We assessed VAP prevalence in ED intubated patients, feasibility of ED VAP prevention, and effect on VAP rates. Methods: This was a quality improvement initiative using a pre/post design. Phase 1 (PRE1) comprised patients before intensive care unit (ICU) bundle deployment. Phase 2 (PRE2) occurred after ICU but before ED deployment. Phase 3 (POST) included patients received VAP prevention starting at ED intubation. Log‐rank test for equality and Cox regression using a Breslow method for ties were performed. Bundle compliance was reported as percentages. Number needed to treat (NNT) was calculated by ventilator day. Results: PRE1, PRE2, and POST groups were composed of 195, 192, and 153 patients, respectively, with VAP rates of 22 (11.3%), 11 (5.7%), and 6 (3.9%). Log‐rank test showed significant reduction in VAP (χ2 = 9.16, P = .0103). The Cox regression hazard ratio was 1.38 for the Clinical Pulmonary Infection Score (P = .001), and the hazard ratio was 0.26 for the VAP bundle (P = .005). Bundle compliance >50% for head‐of‐bed elevation, oral care, subglottic suctioning, and titrated sedation improved significantly with introduction of a registered nurse champion. NNT varied from 7 to 11. Conclusions: VAP was common for ED intubated patients. ED‐based VAP prevention is feasible. We demonstrate significant reduction in VAP rates, which should be replicated in a multicenter study.

Feasibility of Spanish-language acquisition for acute medical care providers: novel curriculum for emergency medicine residencies

Introduction Language and cultural barriers are detriments to quality health care. In acute medical settings, these barriers are more pronounced, which can lead to poor patient outcomes. Materials and methods We implemented a longitudinal Spanish-language immersion curriculum for emergency medicine (EM) resident physicians. This curriculum includes language and cultural instruction, and is integrated into the weekly EM didactic conference, longitudinal over the entire 3-year residency program. Language proficiency was assessed at baseline and annually on the Interagency Language Roundtable (ILR) scale, via an oral exam conducted by the same trained examiner each time. The objective of the curriculum was improvement of resident language skills to ILR level 1+ by year 3. Significance was evaluated through repeated-measures analysis of variance. Results The curriculum was launched in July 2010 and followed through June 2012 (n=16). After 1 year, 38% had improved over one ILR level, with 50% achieving ILR 1+ or above. After year 2, 100% had improved over one level, with 90% achieving the objective level of ILR 1+. Mean ILR improved significantly from baseline, year 1, and year 2 (F=55, df =1; P<0.001). Conclusion Implementation of a longitudinal, integrated Spanish-immersion curriculum is feasible and improves language skills in EM residents. The curriculum improved EM-resident language proficiency above the goal in just 2 years. Further studies will focus on the effect of language acquisition on patient care in acute settings.
