BACKGROUND Available data on the characteristics of patients with Ebola virus disease (EVD) and clinical management of EVD in settings outside West Africa, as well as the complications observed in those patients, are limited. METHODS We reviewed available clinical, laboratory, and virologic data from all patients with laboratory-confirmed Ebola virus infection who received care in U.S. and European hospitals from August 2014 through December 2015. RESULTS A total of 27 patients (median age, 36 years [range, 25 to 75]) with EVD received care; 19 patients (70%) were male, 9 of 26 patients (35%) had coexisting conditions, and 22 (81%) were health care personnel. Of the 27 patients, 24 (89%) were medically evacuated from West Africa or were exposed to and infected with Ebola virus in West Africa and had onset of illness and laboratory confirmation of Ebola virus infection in Europe or the United States, and 3 (11%) acquired EVD in the United States or Europe. At the onset of illness, the most common signs and symptoms were fatigue (20 patients [80%]) and fever or feverishness (17 patients [68%]). During the clinical course, the predominant findings included diarrhea, hypoalbuminemia, hyponatremia, hypokalemia, hypocalcemia, and hypomagnesemia; 14 patients (52%) had hypoxemia, and 9 (33%) had oliguria, of whom 5 had anuria. Aminotransferase levels peaked at a median of 9 days after the onset of illness. Nearly all the patients received intravenous fluids and electrolyte supplementation; 9 (33%) received noninvasive or invasive mechanical ventilation; 5 (19%) received continuous renal-replacement therapy; 22 (81%) received empirical antibiotics; and 23 (85%) received investigational therapies (19 [70%] received at least two experimental interventions). Ebola viral RNA levels in blood peaked at a median of 7 days after the onset of illness, and the median time from the onset of symptoms to clearance of viremia was 17.5 days. A total of 5 patients died, including 3 who had respiratory and renal failure, for a mortality of 18.5%. CONCLUSIONS Among the patients with EVD who were cared for in the United States or Europe, close monitoring and aggressive supportive care that included intravenous fluid hydration, correction of electrolyte abnormalities, nutritional support, and critical care management for respiratory and renal failure were needed; 81.5% of these patients who received this care survived.

Abstract Background: Long-acting inhaled medications are an important component of the treatment of patients with chronic obstructive pulmonary disease (COPD), yet few studies have examined the determinants of medication adherence among this patient population. Objective: We sought to identify factors associated with adherence to long-acting beta-agonists (LABA) and inhaled corticosteroids (ICS) among patients with COPD. Methods: We performed secondary analysis of baseline data collected in a randomized trial of 376 Veterans with spirometrically confirmed COPD. We used electronic pharmacy records to assess adherence, defined as a medication possession ratio of ≥0.80. We investigated the following exposures: patient characteristics, disease severity, medication regimen complexity, health behaviors, confidence in self-management, and perceptions of provider skill. We performed multivariable logistic regression, clustered by provider, to estimate associations. Results: Of the 167 patients prescribed LABA, 54% (n = 90) were adherent to therapy while only 40% (n = 74) of 184 the patients prescribed ICS were adherent. Higher adherence to LABA and ICS was associated with patient perception of their provider as being an “expert” in diagnosing and managing lung disease [For LABA: OR = 21.70 (95% CI 6.79, 69.37); For ICS OR = 7.93 (95% CI 1.71, 36.67)]. Factors associated with adherence to LABA, but not ICS, included: age, education, race, COPD severity, smoking status, and confidence in self-management. Conclusions: Adherence to long-acting inhaled medications among patients with COPD is poor, and determinants of adherence likely differ by medication class. Patient perception of clinician expertise in lung disease was the factor most highly associated with adherence to long-acting therapies.

BACKGROUND Medical errors occur following handoff-related miscommunication. Data regarding the effect on patient-centered outcomes, specifically mortality, are lacking. Our objective was to investigate handoff-related mortality and the effect of duty-hour regulations. METHODS Retrospective cohort study of adult medical patients at a public, university-affiliated hospital from 2010 to 2012. Patients were divided into 2 cohorts: handoff group (discharged within 7 days following a change in resident physician team) vs control group (discharged the 3 weeks of each 4-week rotation before resident service change). The primary outcome was unadjusted and adjusted hospital mortality rate. As a secondary prespecified analysis, we examined the effect of 2011 Accreditation Council for Graduate Medical Education (ACGME) duty-hour changes. RESULTS Among 23,736 patients, unadjusted hospital mortality during the handoff group was higher than the control group (2.68% vs 2.08%, respectively; P = .007; odds ratio [OR] 1.30; 95% confidence interval [CI], 1.08-1.57). Following adjustment, this association remained statistically significant (adjusted OR 1.34; P = .003; 95% CI, 1.10-1.62). Similarly, pre-duty-hour unadjusted hospital mortality was higher in the handoff group vs control group (2.87% vs 2.01%, respectively; P = .006; OR 1.44; 95% CI, 1.11-1.86), which remained statistically significant following adjustment (adjusted OR 1.50; P = .002; 95% CI, 1.16-1.95). However, this association lost statistical significance following duty-hour revision with respect to both unadjusted (2.48% vs 2.15%, respectively; P = .30; OR 1.16; 95% CI, 0.88-1.53) and adjusted mortality (OR 1.18; P = .26; 95% CI, 0.89-1.56). CONCLUSIONS Resident transition in care was significantly associated with an increase in unadjusted and adjusted hospital mortality. Although improved by 2011 ACGME duty-hour amendments, a trend toward higher mortality remained following resident handoff.

BACKGROUND Alcohol has been associated with COPD-related mortality but has not yet been demonstrated to be an independent risk factor for COPD exacerbation. Our objective was to evaluate the association between alcohol consumption and the subsequent risk of COPD exacerbation. METHODS A prospective cohort study of general medicine outpatients seen at one of seven Veterans Affairs (VA) medical centers who returned health screening questionnaires. Three screening questionnaires, AUDIT-C (0 to 12 points), CAGE (0 to 4 points), and a single item about the frequency of drinking six or more drinks on an occasion (binge drinking), were used to classify alcohol consumption. The main outcome, COPD exacerbation, was based on primary VA discharge diagnosis (International Classification of Diseases, Ninth Revision) or outpatient diagnosis of COPD accompanied by prescriptions for either antibiotics or prednisone within 2 days. RESULTS Among the 30,503 patients followed up for a median of 3.35 years, those patients with AUDIT-C scores > or = 6, CAGE scores > or = 2, or who reported binge drinking at least weekly were at an increased risk of COPD exacerbation in age-adjusted analysis. Adjusted hazard ratios were 1.4 (95% confidence interval [CI], 1.1 to 1.7) for AUDIT-C score > or = 6, 1.4 (95% CI, 1.3 to 1.5) for CAGE score > or = 2, and 1.6 (95% CI, 1.2 to 2.2) for those who reported binge drinking daily or almost daily. However, with adjustment for measures of tobacco use, the association between alcohol consumption and increased risk of COPD exacerbation was no longer evident. CONCLUSIONS Alcohol consumption, whether quantified by AUDIT-C, CAGE score, or binge drinking, was not associated with an increased risk of COPD exacerbation independent of tobacco use.

The Surviving Sepsis Campaign Bundle: 2018 update

Mitchell M. Levy; Laura Evans; Andrew Rhodes

Introduction The “sepsis bundle” has been central to the implementation of the Surviving Sepsis Campaign (SSC) from the first publication of its evidence-based guidelines in 2004 through subsequent editions [1–6]. Developed separately from the guidelines publication by the SSC, the bundles have been the cornerstone of sepsis quality improvement since 2005 [7–11]. As noted when they were introduced, the bundle elements were designed to be updated as indicated by new evidence and have evolved accordingly. In response to the publication of “Surviving Sepsis Campaign: International Guidelines for Management of Sepsis and Septic Shock: 2016” [12, 13], a revised “hour-1 bundle” has been developed and is presented below (Fig. 1). The compelling nature of the evidence in the literature, which has demonstrated an association between compliance with bundles and improved survival in patients with sepsis and septic shock, led to the adoption of the SSC measures by the National Quality Forum (NQF) and subsequently both by the New York State (NYS) Department of Health [14] and the Centers for Medicare and Medicaid Services (CMS) [15] in the USA for mandated public reporting. The important relationship between the bundles and survival was confirmed in a publication from this NYS initiative [16]. Paramount in the management of patients with sepsis is the concept that sepsis is a medical emergency. As with polytrauma, acute myocardial infarction, and stroke, early identification and appropriate immediate management in the initial hours after development of sepsis improves outcomes [7–11, 14, 16–21]. The guidelines state that these patients need urgent assessment and treatment, including initial fluid resuscitation while pursuing source control, obtaining further laboratory results, and attaining more precise measurements of hemodynamic status. A guiding principle is that these complex patients need a detailed initial assessment and then ongoing re-evaluation of their response to treatment. The elements of the 2018 bundle, intended to be initiated within the first hour, are listed in Table 1 and presented in the following. Consistent with previous iterations of the SSC sepsis bundles, “time zero” or “time of presentation” is defined as the time of triage in the emergency department or, if referred from another care location, from the earliest chart annotation consistent with all elements of sepsis (formerly severe sepsis) or septic shock ascertained through chart review. Because this new bundle is based on the 2016 Guidelines publication, the guidelines themselves should be referred to for further discussion and evidence related to each element and to sepsis management as a whole.

Importance Shift-to-shift transitions in care among house staff are associated with adverse events. However, the association between end-of-rotation transition (in which care of the patient is transferred) and adverse events is uncertain. Objective To examine the association of end-of-rotation house staff transitions with mortality among hospitalized patients. Design, Setting, and Participants Retrospective multicenter cohort study of patients admitted to internal medicine services (N = 230 701) at 10 university-affiliated US Veterans Health Administration hospitals (2008-2014). Exposures Transition patients (defined as those admitted prior to an end-of-rotation transition who died or were discharged within 7 days following transition) were stratified by type of transition (intern only, resident only, or intern + resident) and compared with all other discharges (control). An alternative analysis comparing admissions within 2 days before transition with admissions on the same 2 days 2 weeks later was also conducted. Main Outcomes and Measures The primary outcome was in-hospital mortality. Secondary outcomes included 30-day and 90-day mortality and readmission rates. A difference-in-difference analysis assessed whether outcomes changed after the 2011 Accreditation Council for Graduate Medical Education (ACGME) duty hour regulations. Adjustments included age, sex, race/ethnicity, month, year, length of stay, comorbidities, and hospital. Results Among 230 701 patient discharges (mean age, 65.6 years; men, 95.8%; median length of stay, 3.0 days), 25 938 intern-only, 26 456 resident-only, and 11 517 intern + resident end-of-rotation transitions occurred. Overall mortality was 2.18% in-hospital, 9.45% at 30 days, and 14.43% at 90 days. Adjusted hospital mortality was significantly greater in transition vs control patients for the intern-only group (3.5% vs 2.0%; odds ratio [OR], 1.12 [95% CI, 1.03-1.21]) and the intern + resident group (4.0% vs 2.1%; OR, 1.18 [95% CI, 1.06-1.33]), but not for the resident-only group (3.3% vs 2.0%; OR, 1.07 [95% CI, 0.99-1.16]). Adjusted 30-day and 90-day mortality rates were greater in all transition vs control comparisons (30-day mortality: intern-only group, 14.5% vs 8.8%, OR, 1.17 [95% CI, 1.13-1.22]; resident-only group, 13.8% vs 8.9%, OR, 1.11 [95% CI, 1.04-1.18]; intern + resident group, 15.5% vs 9.1%, OR, 1.21 [95% CI, 1.12-1.31]; 90-day mortality: intern-only group, 21.5% vs 13.5%, OR, 1.14 [95% CI, 1.10-1.19]; resident-only group, 20.9% vs 13.6%, OR, 1.10 [95% CI, 1.05-1.16]; intern + resident group, 22.8% vs 14.0%, OR, 1.17 [95% CI, 1.11-1.23]). Duty hour changes were associated with greater adjusted hospital mortality for transition patients in the intern-only group and intern + resident group than for controls (intern-only: OR, 1.11 [95% CI, 1.02-1.21]; intern + resident: OR, 1.17 [95% CI, 1.02-1.34]). The alternative analyses did not demonstrate any significant differences in mortality between transition and control groups. Conclusions and Relevance Among patients admitted to internal medicine services in 10 Veterans Affairs hospitals, end-of-rotation transition in care was associated with significantly higher in-hospital mortality in an unrestricted analysis that included most patients, but not in an alternative restricted analysis. The association was stronger following institution of ACGME duty hour regulations.

Monitoring of the physical exam in sepsis.

Radu Postelnicu; Laura Evans

Purpose of review Monitoring of mental status and peripheral circulatory changes can be accomplished noninvasively in patients in the ICU. Emphasis on physical examination in conditions such as sepsis have gained increased attention as these evaluations can often serve as a surrogate marker for short-term treatment efficacy of therapeutic interventions. Sepsis associated encephalopathy and mental status changes correlate with worse prognosis in patients. Evaluation of peripheral circulation has been shown to be a convenient, easily accessible, and accurate marker for prognosis in patients with septic shock. The purpose of this article is to emphasize the main findings according to recent literature into the monitoring of physical examination changes in patients with sepsis. Recent findings Several recent studies have expanded our knowledge about the pathophysiology of mental status changes and the clinical assessment of peripheral circulation in patients with sepsis. Sepsis-associated encephalopathy is associated with an increased rate of morbidity and mortality in an intensive care setting. Increased capillary refill time (CRT) and persistent skin mottling are strongly predictive of mortality, whereas temperature gradients can reveal vasoconstriction and more severe organ dysfunction. Summary Monitoring of physical examination changes is a significant and critical intervention in patients with sepsis. Utilizing repeated neurologic evaluations, and assessing CRT, mottling score, and skin temperature gradients should be emphasized as important noninvasive diagnostic tools. The significance of these methods can be incorporated during the utilization of therapeutic strategies in resuscitation protocols in patients with sepsis.

ObjectiveTo identify research priorities in the management, epidemiology, outcome and underlying causes of sepsis and septic shock.DesignA consensus committee of 16 international experts representing the European Society of Intensive Care Medicine and Society of Critical Care Medicine was convened at the annual meetings of both societies. Subgroups had teleconference and electronic-based discussion. The entire committee iteratively developed the entire document and recommendations.MethodsEach committee member independently gave their top five priorities for sepsis research. A total of 88 suggestions (ESM 1 - supplemental table 1) were grouped into categories by the committee co-chairs, leading to the formation of seven subgroups: infection, fluids and vasoactive agents, adjunctive therapy, administration/epidemiology, scoring/identification, post-intensive care unit, and basic/translational science. Each subgroup had teleconferences to go over each priority followed by formal voting within each subgroup. The entire committee also voted on top priorities across all subgroups except for basic/translational science.ResultsThe Surviving Sepsis Research Committee provides 26 priorities for sepsis and septic shock. Of these, the top six clinical priorities were identified and include the following questions: (1) can targeted/personalized/precision medicine approaches determine which therapies will work for which patients at which times?; (2) what are ideal endpoints for volume resuscitation and how should volume resuscitation be titrated?; (3) should rapid diagnostic tests be implemented in clinical practice?; (4) should empiric antibiotic combination therapy be used in sepsis or septic shock?; (5) what are the predictors of sepsis long-term morbidity and mortality?; and (6) what information identifies organ dysfunction?ConclusionsWhile the Surviving Sepsis Campaign guidelines give multiple recommendations on the treatment of sepsis, significant knowledge gaps remain, both in bedside issues directly applicable to clinicians, as well as understanding the fundamental mechanisms underlying the development and progression of sepsis. The priorities identified represent a roadmap for research in sepsis and septic shock.

Implementation of a multicenter performance improvement program for early detection and treatment of severe sepsis in general medical-surgical wards.

Christa Schorr; Andrew Odden; Laura Evans; Gabriel J. Escobar; Snehal Gandhi; Sean R. Townsend; Mitchell M. Levy

Sepsis is a leading cause of in-hospital death, and evidence suggests a higher mortality in patients presenting with sepsis on the ward compared to those presenting to the emergency department. Ward patients who develop severe sepsis may have poor outcomes for a variety of reasons, including delayed diagnosis, lack of readily available staffing, and delayed treatment. We report on a multihospital quality improvement program for early detection and treatment of sepsis on general medical-surgical wards. We describe a multipronged approach to improve severe sepsis outcomes using the Institute for Healthcare Improvements Plan-Do-Study-Act model. Sixty sites engaged in a collaborative implementation process that aligned people, process, and technology. Based on our experience, we recommend a stepwise approach to implement such a program: (1) both administrative and clinical leadership commit to a common goal; (2) appoint clinical champions and give them authority to engage other clinicians to improve timeliness of interventions; (3) map workflows and processes to rely heavily on the nursing staffs ability to evaluate and report severe sepsis screening results; (4) if available, design and deploy technology with the assistance of clinical informaticians (eg, to enable electronic health records-based continuous screening); (5) to determine success, consider tracking screening compliance and process, and outcome measures such as length of stay and mortality.

Factors Associated With Utilization of an Inpatient Palliative Care Consultation Service in an Urban Public Hospital

Pavan Bhatraju; Allison Friedenberg; Amit Uppal; Laura Evans

Rationale: To evaluate factors associated with palliative care consultation (PCC) in an urban public hospital. Methods: A retrospective chart review of patients who died on inpatient medical services. Results: Patients with a PCC were more likely to have a “do not resuscitate” (DNR) order at the time of death (p<0.001) and had a decreased likelihood of death in the ICU (p<0.001). Factors associated with PCC in a multivariate analysis included: cancer diagnosis (p=0.01), at least a high school education (p=0.04), older age (p=.003), and birth outside the US (p=0.03). Conclusion: The increased PCC utilization for immigrants is in contrast to previously reported literature. This increased use may be because access to services in a municipal hospital is not driven by demographic and socioeconomic factors.
