WASH activities at two Ebola treatment units in Sierra Leone.

PURPOSE: The 2014 outbreak of Ebola virus disease (EVD) in West Africa was the largest in history. Starting in September 2014, International Medical Corps (IMC) operated five Ebola treatment units (ETUs) in Sierra Leone and Liberia. This paper explores how future infectious disease outbreak facilities in resource-limited settings can be planned, organized, and managed by analyzing data collected on water, sanitation, and hygiene (WASH) and infection prevention control (IPC) protocols. DESIGN/METHODOLOGY/APPROACH: We conducted a retrospective cohort study by analyzing WASH/IPC activity data routinely recorded on paper forms or white boards at ETUs during the outbreak and later merged into a database from two IMC-run ETUs in Sierra Leone between December 2014 and December 2015. FINDINGS: The IMC WASH/IPC database contains data from over 369 days. Our results highlight parameters key to designing and maintaining an ETU. High concentration chlorine solution usage was highly correlated with both daily patient occupancy and high-risk zone staff entries; low concentration chlorine usage was less well explained by these measures. There is high demand for laundering and disinfecting of personal protective equipment (PPE) on a daily basis and approximately 1 (0-4) piece of PPE is damaged each day. RESEARCH LIMITATIONS/IMPLICATIONS: Lack of standardization in the type and format of data collected at ETUs made constructing the WASH/IPC database difficult. However, the data presented here may help inform humanitarian response operations in future epidemics.

International Emergency Medical Teams Training Workshop Special Report.

The World Health Organization's (WHO; Geneva, Switzerland) Emergency Medical Team (EMT) Initiative created guidelines which define the basic procedures to be followed by personnel and teams, as well as the critical points to discuss before deploying a field hospital. However, to date, there is no formal standardized training program established for EMTs before deployment. Recognizing that the World Association of Disaster and Emergency Medicine (WADEM; Madison, Wisconsin USA) Congress brings together a diverse group of key stakeholders, a pre-Congress workshop was organized to seek out collective expertise and to identify key EMT training competencies for the future development of training programs and protocols. The future of EMT training should include standardization of curriculum and the recognition or accreditation of selected training programs. The outputs of this pre-WADEM Congress workshop provide an initial contribution to the EMT Training Working Group, as this group works on mapping training, competencies, and curriculum. Common EMT training themes that were identified as fundamental during the pre-Congress workshop include: the ability to adapt one's professional skills to low-resource settings; context-specific training, including the ability to serve the needs of the affected population in natural disasters; training together as a multi-disciplinary EMT prior to deployment; and the value of simulation in training.

The Management of the Khan Al-Assal Chemical Attack in Aleppo University Hospital (AUH).

On March 19, 2013, Khan al-Assal was attacked with chemical weapons. In total, 20 people were killed and an additional 124 were injured; 63 people were cared for at Aleppo University Hospital on that day, where 14 died, all of them were civilians; 7 men, 6 women, and 1 child. This is a brief first hand report, for what has now become a more frequent, more deadly and horrific event in the lives of many Syrians. (Disaster Med Public Health Preparedness. 2018;12:663-665).

The Zika Virus Outbreak in Brazil: Knowledge Gaps and Challenges for Risk Reduction.

We analyzed uncertainties and complexities of the Zika virus outbreak in Brazil, and we discuss risk reduction for future emergencies. We present the public health situation in Brazil and concurrent determinants of the epidemic and the knowledge gaps that persist despite building evidence from research, making public health decisions difficult. Brazil has adopted active measures, but producing desired outcomes may be uncertain because of partial or unavailable information. Reducing population group vulnerabilities and acting on environmental issues are medium- to long-term measures. Simultaneously dealing with information gaps, uncontrolled disease spread, and vulnerabilities is a new risk scenario and must be approached decisively to face emerging biothreats.

The Solidarity and Health Neutrality of Physicians in War & Peace.

The wars in the Middle East have led to unprecedented threats and attacks on patients, healthcare workers, and purposeful targeting of hospitals and medical facilities. It is crucial that every healthcare provider, both civilian and military, on either side of the conflict become aware of the unique and inherent protections afforded to them under International Humanitarian Law. However, these protections come with obligations. Whereas Governments must guarantee these protections, when violated, medical providers have equal duty and obligations under the Law to ensure that they will neither commit nor assist in these violations nor take part in any act of hostility. Healthcare providers must not allow any inhuman or degrading treatment of which they are aware and must report such actions to the appropriate authorities. Failure to do so leads to risks of moral, ethical and legal consequences as well as penalties for their actions and inactions. There must be immediate recognition by all parties of the neutrality of health care workers and their rights and responsibilities to care for any sick and injured patient, regardless of their nationality, race, religion, or political point of view.

An Electronic Competency-Based Evaluation Tool for Assessing Humanitarian Competencies in a Simulated Exercise.

METHODS: The evaluation tool was first derived from the formerly Consortium of British Humanitarian Agencies' (CBHA; United Kingdom), now "Start Network's," Core Humanitarian Competency Framework and formatted in an electronic data capture tool that allowed for offline evaluation. During a 3-day humanitarian simulation event, participants in teams of eight to 10 were evaluated individually at multiple injects by trained evaluators. Participants were assessed on five competencies and a global rating scale. Participants evaluated both themselves and their team members using the same tool at the end of the simulation exercise (SimEx). RESULTS: All participants (63) were evaluated. A total of 1,008 individual evaluations were completed. There were 90 (9.0%) missing evaluations. All 63 participants also evaluated themselves and each of their teammates using the same tool. Self-evaluation scores were significantly lower than peer-evaluations, which were significantly lower than evaluators' assessments. Participants with a medical degree, and those with humanitarian work experience of one month or more, scored significantly higher on all competencies assessed by evaluators compared to other participants. Participants with prior humanitarian experience scored higher on competencies regarding operating safely and working effectively as a team member. CONCLUSION: This study presents a novel electronic evaluation tool to assess individual performance in five of six globally recognized humanitarian competency domains in a 3-day humanitarian SimEx. The evaluation tool provides a standardized approach to the assessment of humanitarian competencies that cannot be evaluated through knowledge-based testing in a classroom setting. When combined with testing knowledge-based competencies, this presents an approach to a comprehensive competency-based assessment that provides an objective measurement of competency with respect to the competencies listed in the Framework. There is an opportunity to advance the use of this tool in future humanitarian training exercises and potentially in real time, in the field. This could impact the efficiency and effectiveness of humanitarian operations. Evans AB , Hulme JM , Nugus P , Cranmer HH , Coutu M , Johnson K .

Academic Institutions' Critical Guidelines for Health Care Workers Who Deploy to West Africa for the Ebola Response and Future Crises.

The unprecedented Ebola Virus Disease (EVD) outbreak in West Africa, with its first cases documented in March 2014, has claimed the lives of thousands of people, and it has devastated the health care infrastructure and workforce in affected countries. Throughout this outbreak, there has been a critical lack of health care workers (HCW), including physicians, nurses, and other essential non-clinical staff, who have been needed, in most of the affected countries, to support the medical response to EVD, to attend to the health care needs of the population overall, and to be trained effectively in infection protection and control. This lack of sufficient and qualified HCW is due in large part to three factors: 1) limited HCW staff prior to the outbreak, 2) disproportionate illness and death among HCWs caused by EVD directly, and 3) valid concerns about personal safety among international HCWs who are considering responding to the affected areas. These guidelines are meant to inform institutions who deploy professional HCWs.

Strengthening the detection of and early response to public health emergencies: lessons from the West African Ebola epidemic.

Mark Siedner and colleagues reflect on the early response to the Ebola epidemic and lessons that can be learned for future epidemics.

Sign me up: rules of the road for humanitarian volunteers during the Ebola outbreak.

The current Ebola outbreak is the worst global public health emergency of our generation, and our global health care community must and will rise to serve those affected. Aid organizations participating in the Ebola response must carefully plan to carry out their responsibility to ensure the health, safety, and security of their responders. At the same time, individual health care workers and their employers must evaluate the ability of an aid organization to protect its workers in the complex environment of this unheralded Ebola outbreak. We present a minimum set of operational standards developed by a consortium of Boston-based hospitals that a professional organization should have in place to ensure the health, safety, and security of its staff in response to the Ebola virus disease outbreak.

Development of an evaluation framework suitable for assessing humanitarian workforce competencies during crisis simulation exercises.

The need to provide a professionalization process for the humanitarian workforce is well established. Current competency-based curricula provided by existing academically affiliated training centers in North America, the United Kingdom, and the European Union provide a route toward certification. Simulation exercises followed by timely evaluation is one way to mimic the field deployment process, test knowledge of core competences, and ensure that a competent workforce can manage the inevitable emergencies and crises they will face. Through a 2011 field-based exercise that simulated a humanitarian crisis, delivered under the auspices of the World Health Organization (WHO), a competency-based framework and evaluation tool is demonstrated as a model for future training and evaluation of humanitarian providers.

Academic affiliated training centers in humanitarian health, Part I: program characteristics and professionalization preferences of centers in North America.

The collaborative London based non-governmental organization network ELRHA (Enhancing Learning and Research for Humanitarian Assistance) supports partnerships between higher education institutions and humanitarian organizations worldwide with the objective to enhance the professionalization of the humanitarian sector. While coordination and control of the humanitarian sector has plagued the response to every major crisis, concerns highlighted by the 2010 Haitian earthquake response further catalyzed and accelerated the need to ensure competency-based professionalization of the humanitarian health care work force. The Harvard Humanitarian Initiative sponsored an independent survey of established academically affiliated training centers in North America that train humanitarian health care workers to determine their individual training center characteristics and preferences in the potential professionalization process. The survey revealed that a common thread of profession-specific skills and core humanitarian competencies were being offered in both residential and online programs with additional programs offering opportunities for field simulation experiences and more advanced degree programs. This study supports the potential for the development of like-minded academic affiliated and competency-based humanitarian health programs to organize themselves under ELRHA's regional "consultation hubs" worldwide that can assist and advocate for improved education and training opportunities in less served developing countries.

Assessment of knowledge retention and the value of proctored ultrasound exams after the introduction of an emergency ultrasound curriculum.

BACKGROUND: Optimal training required for proficiency in bedside ultrasound is unknown. In addition, the value of proctored training is often assumed but has never been quantified. METHODS: To compare different training regimens for both attending physicians and first year residents (interns), a prospective study was undertaken to assess knowledge retention six months after an introductory ultrasound course. Eighteen emergency physicians and twelve emergency medicine interns were assessed before and 6 months after an introductory ultrasound course using a standardized, image-based ultrasound test. In addition, the twelve emergency medicine interns were randomized to a group which received additional proctored ultrasound hands-on instruction from qualified faculty or to a control group with no hands-on instruction to determine if proctored exam training impacts ultrasound knowledge. Paired and unpaired estimates of the median shift in test scores between groups were made with the Hodges-Lehmann extension of the Wilcoxon-Mann-Whitney test. RESULTS: Six months after the introductory course, test scores (out of a 24 point test) were a median of 2.0 (95% CI 1.0 to 3.0) points higher for residents in the control group, 5.0 (95% CI 3.0 to 6.0) points higher for residents in the proctored group, and 2.5 (95% CI 1.0 to 4.0) points higher for the faculty group. Residents randomized to undergo proctored ultrasound examinations exhibited a higher score improvement than their cohorts who were not with a median difference of 3.0 (95% CI 1.0 to 5.0) points. CONCLUSION: We conclude that significant improvement in knowledge persists six months after a standard introductory ultrasound course, and incorporating proctored ultrasound training into an emergency ultrasound curriculum may yield even higher knowledge retention.

The sensitivity of cardiac markers stratified by symptom duration.

We compared the sensitivity of three commonly used cardiac markers between two subpopulations, those who came to the Emergency Department (ED) late (6-24 h) after their symptoms began, and those who arrived earlier (<6 h), in a prospective comparative trial. Among all adult patients who presented to our ED with symptoms suggestive of acute myocardial infarction (MI), we drew serum for myoglobin, CK-MB, and troponin I upon arrival (time 0) and 2 h later. Outcomes, including acute MI, were determined. Sensitivities for all three markers between the subpopulations who arrived fewer than 6 h from symptom onset were compared to those who arrived later (6-24 h). We enrolled 346 eligible subjects, 36% of whom described cardiac symptoms as beginning 6 or more hours earlier; 14% suffered acute MIs. For time 0, the sensitivity of all three markers for acute MI was significantly higher among those subjects with symptoms of 6 or more hours' duration as compared to those with less. For troponin I, the increase in sensitivity between these two subpopulations approached 300%. At the time of the 2-h sample, the differences in sensitivities were much less and were not statistically significant. We conclude that cardiac marker values obtained at time 0 among Emergency Department patients who arrive 6 or more hours after cardiac symptom onset provide significantly higher sensitivities as compared to those obtained in patients who arrive earlier. For troponin I, the increase in sensitivity approaches threefold.

Predictors of revascularization among emergency department patients who are evaluated for acute coronary syndrome.

BACKGROUND: To determine, among patients who present to the emergency department with symptoms suggestive of acute coronary syndrome (ACS), predictors of short-term revascularization. METHODS: A prospective descriptive trial was performed. Potential predictors for revascularization were measured by means of a questionnaire of providers, serum for cardiac biomarkers, and an initial ECG. The primary outcome of revascularization (coronary bypass graft or percutaneous intervention) was determined through a medical record review. Potential predictors of revascularization were entered into a family of logistic regressions. RESULTS: 341 eligible subjects were enrolled, of whom 14% underwent revascularization. The predictors of revascularization included ST elevation on initial ECG (odds ratio 12.0), and an elevation in troponin I (odds ratio 8.9), CKMB (odds ratio 6.8), or myoglobin (odds ratio 4.7) on admission. When all three biomarkers competed in the same model, troponin I appeared to be the strongest predictor of short-term revascularization. CONCLUSION: In a single site study, among emergency department patients with symptoms suggestive of ACS, ST elevation on initial ECG and an elevation in troponin I, CK-MB, and myoglobin upon presentation all predicted short -term revascularization. Among the three biomarkers, elevation in troponin I was the strongest predictor. ABBREVIATED ABSTRACT: We conducted a prospective descriptive trial to identify predictors of short-term revascularization among 341 emergency department patients who presented with symptoms suggestive of ACS. Fourteen percent of the study population received revascularization. Predictors of revascularization included ST elevation on initial ECG (odds ratio 12.0.), and an elevation in troponin I (odds ratio 8.9), CKMB (odds ratio 6.8), or myoglobin (odds ratio 4.7) on admission. When all three biomarkers competed in the same model, troponin I appeared to be the strongest predictor of short-term revascularization.

Disagreement between formal and medical record criteria for the diagnosis of acute coronary syndrome.

OBJECTIVES: To measure agreement between formal and medical record criteria for the diagnosis of acute coronary syndrome (ACS) among patients undergoing an emergency department evaluation for potential acute coronary symptoms. METHODS: Cases of ACS were determined by both formal (World Health Organization 1984 criteria for acute myocardial infarction [AMI], Braunwald criteria for unstable angina pectoris [UAP]) and medical record criteria. In the latter, a diagnosis was made if providers indicated AMI or UAP anywhere in the medical record. All information included in formal criteria was available to clinicians establishing the medical record diagnosis. The two criteria for diagnosis were compared, and a kappa value was recorded. Two blinded observers adjudicated discordant cases, with a kappa value recorded. Disagreements between these two coinvestigators were resolved by a Delphi technique. RESULTS: A total of 375 eligible subjects were enrolled, of whom 65 (17%; 45 AMI, 20 UAP) had ACS by both sets of criteria. Formal and medical record criteria disagreed in 32 subjects. This represented 9% (95% confidence interval = 6% to 12%) of the overall study population but 33% (95% confidence interval = 23% to 43%) of subjects with possible ACS. Coinvestigators acting as judges and blinded to each other's determinations agreed that 25 of these subjects had ACS and three did not; they disagreed on four subjects (kappa = 0.54). Among these four subjects, a Delphi consensus technique determined that two subjects had AMI and two had no ACS. CONCLUSIONS: In a single-site study, among subjects who have possible ACS as determined by either or both formal and medical record criteria, these two sets of criteria disagree in almost one third of cases. Among discordant cases, even two expert judges frequently disagreed on the final diagnosis. A modified Delphi technique to address these disagreements is described.

Predictors of delay in presentation to the ED in patients with suspected acute coronary syndromes.

Delays in seeking medical attention for patients with acute coronary syndromes (ACS) preclude early application of life-saving treatment and diminish efficacy. Previous studies suggest 3-hour delays between onset of symptoms and ED arrival in patients with typical presentations of acute myocardial infarction (AMI). A prospective observational study was conducted in an urban ED measuring lag time (LT) among adults presenting within 48 hours of onset of symptoms suggestive of ACS. Univariate and multiple regression analyses were performed on 5 predictors: age, sex, symptoms at presentation, and 2 different outcomes (AMI and ACS). Three hundred seventy-four patients were enrolled. Mean age was 63 years with 38% 70 years or older. Seventy-three percent of all patients with suspected ACS presented with chest pain, 27% with atypical symptoms. Overall mean LT was 8.7 hours (standard deviation 11). In subgroup analysis, patients aged >/=70 years were more likely to have LTs >12 hours (29% vs. 19% P =.043) and patients without chest pain had longer mean LTs (11.6 vs. 7.6 hours, P =.01). Delay in ED presentation is group specific. Advanced age and patients with atypical symptoms are predictive of longer LTs. Contrary to previously published data, patients with symptoms suspicious for ACS can delay an average of 9 hours, which might alter current thinking in the prevention and care of these patients.
