Importance: Refugees and internally displaced persons are highly vulnerable to sexual violence during conflict and subsequent displacement. However, accurate estimates of the prevalence of sexual violence among in these populations remain uncertain. Objective: Our objective was to estimate the prevalence of sexual violence among refugees and displaced persons in complex humanitarian emergencies. Data Source: We conducted systematic review of relevant literature in multiple databases (EMBASE, CINAHL, and MEDLINE) through February 2013 to identify studies. We also reviewed reference lists of included articles to identify any missing sources. Study Selection: Inclusion criteria required identification of sexual violence among refugees and internally displaced persons or those displaced by conflict in complex humanitarian settings. Studies were excluded if they did not provide female sexual violence prevalence, or that included only single case reports, anecdotes, and those that focused on displacement associated with natural disasters. After a review of 1175 citations 19 unique studies were selected. Data Extraction: Two reviewers worked independently to identify final selection and a third reviewer adjudicated any differences. Descriptive and quantitative information was extracted; prevalence estimates were synthesized. Heterogeneity was assessed using I2. Main Outcomes: The main outcome of interest was sexual violence among female refugees and internally displaced persons in complex humanitarian settings. Results: The prevalence of sexual violence was estimated at 21.4% (95% CI, 14.9-28.7; I2=98.3%), using a random effects model. Statistical heterogeneity was noted with studies using probability sampling designs reporting lower prevalence of sexual violence (21.0%, 95% CI, 13.2-30.1; I2=98.6%), compared to lower quality studies (21.7%, 95% CI, 11.5-34.2; I2=97.4%). We could not rule out the presence of publication bias. Conclusions: The findings suggest that approximately one in five refugees or displaced women in complex humanitarian settings experienced sexual violence. However, this is likely an underestimation of the true prevalence given the multiple existing barriers associated with disclosure. The long-term health and social consequences of sexual violence for women and their families necessitate strategies to improve identification of survivors of sexual violence and increase prevention and response interventions in these complex settings.

Development of a screening tool to identify female survivors of gender-based violence in a humanitarian setting: qualitative evidence from research among refugees in Ethiopia

Andrea L. Wirtz; Nancy Glass; Kiemanh Pham; Amsale Aberra; Leonard S. Rubenstein; Sonal Singh; Alexander Vu

BackgroundHigh levels of gender-based violence (GBV) persist among conflict-affected populations and within humanitarian settings and are paralleled by under-reporting and low service utilization. Novel and evidence-based approaches are necessary to change the current state of GBV amongst these populations. We present the findings of qualitative research, which were used to inform the development of a screening tool as one potential strategy to identify and respond to GBV for females in humanitarian settings.MethodsQualitative research methods were conducted from January-February 2011 to explore the range of experiences of GBV and barriers to reporting GBV among female refugees. Individual interview participants (n=37) included female refugees (≥15 years), who were survivors of GBV, living in urban or one of three camps settings in Ethiopia, and originating from six conflict countries. Focus group discussion participants (11 groups; 77 participants) included health, protection and community service staff working in the urban or camp settings. Interviews and discussions were conducted in the language of preference, with assistance by interpreters when needed, and transcribed for analysis by grounded-theory technique.ResultsSingle and multiple counts of GBV were reported and ranged from psychological and social violence; rape, gang rape, sexual coercion, and other sexual violence; abduction; and physical violence. Domestic violence was predominantly reported to occur when participants were living in the host country. Opportunistic violence, often manifested by rape, occurred during transit when women depended on others to reach their destination. Abduction within the host country, and often across borders, highlighted the constant state of vulnerability of refugees. Barriers to reporting included perceived and experienced stigma in health settings and in the wider community, lack of awareness of services, and inability to protect children while mothers sought services.ConclusionsFindings demonstrate that GBV persists across the span of the refugee experience, though there is a transition in the range of perpetrators and types of GBV that are experienced. Further, survivors experience significant individual and system barriers to disclosure and service utilization. The findings suggest that routine GBV screening by skilled service providers offers a strategy to confidentially identify and refer survivors to needed services within refugee settings, potentially enabling survivors to overcome existing barriers.

International Emergency Medicine and Global Health: Training and Career Paths for Emergency Medicine Residents

Melinda J. Morton; Alexander Vu

Emergency medicine is at a unique and exciting interface between medicine and public health, in a way that no other specialty of medical practice can match. In the emergency department (ED), the community at large and the health care system interact at their most basic and fundamental way. Every event that affects the health of a community will reflect more rapidly in the ED than anywhere else; be it a hurricane or flood, an infectious disease epidemic, violent crime, increasing rates of drug and alcohol addiction, intimate partner violence and child maltreatment, or a lack of adequate health insurance coverage, the specialty of emergency medicine is truly at the heart of the public’s health. As health care providers of last resort, emergency physicians are also faced with a variety of clinical challenges that exist nowhere else in the profession of medicine. Given the tremendous array of presentations and problems faced by the emergency physician, the publication of high-quality and applicable scientific literature, and the ability to appropriately use this information, is critical to the practice of our specialty. The Residents’ Perspective section of Annals of Emergency Medicine, now in its 13th year, serves as an important forum for resident viewpoints on these many and varied pressing issues that face our specialty, as well as for the application of the best current evidence to aspects of clinical practice most relevant to residents. As emergency medicine residents, we are faced not only with the challenge of mastering a vast body of knowledge but also with the task of learning to read and evaluate new clinical evidence, and even to participate in the writing and development of new knowledge to enhance and augment our clinical acumen. Given the relatively nascent nature of the specialty of emergency medicine in comparison with many other medical specialties, the application and use of such evidence is all the more relevant and timely in the continuing refinement of our principles and practice. The Residents’ Perspective section’s goal is to reflect the clinical and academic concerns and efforts of our resident audience. The potential for topics of discussion is as vast as the breadth of our specialty and includes discussions on ethical dilemmas, clinical decision rules and evidence-based medicine, emergency medicine and public health, resident career paths, f

INTRODUCTION In the aftermath of Hurricane Katrina, a significant number of faith-based organizations (FBOs) that were not a part of the formal National Response Plan (NRP) initiated and sustained sheltering operations. OBJECTIVE The objective of this study was to examine the sheltering operations of FBOs, understand the decision-making process of FBO shelters, and identify the advantages and disadvantages of FBO shelters. METHODS Verbal interviews were conducted with FBO shelter leaders. Inclusion criteria were: (1) opening in response to the Katrina disaster; (2) operating for more than three weeks; and (3) being a FBO. Enrolled shelters were examined using descriptive data methods. RESULTS The majority of shelters operating in Mississippi up to three weeks post-Katrina were FBO-managed. All of the operating FBO shelters in Mississippi that met the inclusion criteria were contacted with a response rate of 94%. Decisions were made by individuals or small groups in most shelters regarding opening, operating procedures, and closing. Most FBOs provided at least one enabling service to evacuees, and all utilized informal networks for sheltering operations. Only 25% of FBOs had disaster plans in place prior to Hurricane Katrina. CONCLUSIONS Faith-based organization shelters played a significant role in the acute phase of the Katrina disaster. Formal disaster training should be initiated for these organizations. Services provided by FBOs should be standardized. Informal networks should be incorporated into national disaster planning.

Reliability of the Marlowe-Crowne social desirability scale in Ethiopia, Kenya, Mozambique, and Uganda

Alexander Vu; Nhan Tran; Kiemanh Pham; Saifuddin Ahmed

BackgroundStudies of HIV often use self-reported surveys to measure sexual knowledge, attitudes, and practices. However, the self-reported data are vulnerable to social desirability (SD), a propensity of individuals to report favorable responses. The Marlowe-Crowne Social Desirability Scale (MC-SDS) was developed as a measure of the effect of social desirability, but it has not been adapted for or used in Africa. This study aimed to apply the MC-SDS nested in an HIV behavioral intervention program and to measure its reliability in four African countries.MethodsThe MC-SDS was adapted based on consultations with local stakeholders and pilot tested in Ethiopia, Kenya, Mozambique, and Uganda. Trained interviewers administered the modified 28-item MC-SDS survey to 455 men and women (ages 15-24 years). The scores for the social desirability scales were calculated for all participants. An analysis of the internal consistency of responses was conducted using the Cronbachs α coefficient. Acceptable internal consistency was defined as an α coefficient of ≥ 0.70.ResultsMean social desirability scores ranged from a low of 15.7 in Kenya to a high of 20.6 in Mozambique. The mean score was 17.5 for Uganda and 20.6 for Mozambique. The Cronbachs α coefficients were 0.63 in Kenya, 0.66 in Mozambique, 0.70 in Uganda, and 0.80 in Ethiopia.ConclusionsThe MC-SDS can be effectively adapted and implemented in sub-Saharan Africa. The reliability of responses in these settings suggest that the MC-SDS could be a useful tool for capturing potential SD in surveys of HIV related risk behaviors.

BACKGROUND Injecting drug use is the primary mode of HIV transmission and acquisition in Afghanistan. People who inject drugs (PWID) in the country have been characterized by high risk injecting behavior and a high burden of HCV infection. We aimed to estimate the burden of HIV, HCV, and other infectious diseases and to identify the correlates of HIV and HCV infection among PWID living in three major Afghan cities in 2009. METHODS Epidemiologic data was collected among PWID for the integrated biological and behavioral surveillance (IBBS) survey between May and August, 2009 in three Afghan cities. Data were collected using a structured questionnaire and biologic specimens to screen for HIV, HBV, HCV, syphilis, and HSV-2 using rapid testing kits. Multiple logistic regression models were constructed to identify correlates of infection. RESULTS Among 548 participants, pooled HIV prevalence was 7.1% (Mazar-i-Sharif: 1.0%, Kabul: 3.1%, Herat: 18.4%) and HCV prevalence was 40.3%. Almost all participants with HIV infection were co-infected with HCV (94.9%). Pooled prevalence estimates for other diseases included 7.1% for HBV, 5.5% for syphilis; and 9.3% for HSV-2. Living in Herat, ever in prison and time injecting were independently associated with HIV infection. Living in Kabul, Herat and time injecting were independently associated with HCV infection. CONCLUSIONS There is a high and heterogeneous burden of HIV and HCV among PWID in Afghan cities. Provision of comprehensive harm reduction services to PWID in Afghanistan is warranted to reduce exposures associated with HIV and HCV infection, especially in the city of Herat.

Medically underserved populations in the United States continue to experience higher cancer burdens of incidence, mortality, and other cancer-related outcomes. It is imperative to understand how health inequities experienced by diverse population groups may contribute to our increasing unequal cancer burdens and disparate outcomes. The National Cancer Institute convened a diverse group of scientists to discuss research challenges and opportunities for cancer epidemiology in medically underserved and understudied populations. This report summarizes salient issues and discusses five recommendations from the group, including the next steps required to better examine and address cancer burden in the United States among our rapidly increasing diverse and understudied populations.

Earthquake related injuries in the pediatric population : a systematic review

Gabrielle A. Jacquet; Bhakti Hansoti; Alexander Vu; Jamil D. Bayram

Background: Children are a special population, particularly susceptible to injury. Registries for various injury types in the pediatric population are important, not only for epidemiological purposes but also for their implications on intervention programs. Although injury registries already exist, there is no uniform injury classification system for traumatic mass casualty events such as earthquakes. Objective: To systematically review peer-reviewed literature on the patterns of earthquake-related injuries in the pediatric population. Methods: On May 14, 2012, the authors performed a systematic review of literature from 1950 to 2012 indexed in Pubmed, EMBASE, Scopus, Web of Science, and Cochrane Library. Articles written in English, providing a quantitative description of pediatric injuries were included. Articles focusing on other types of disasters, geological, surgical, conceptual, psychological, indirect injuries, injury complications such as wound infections and acute kidney injury, case reports, reviews, and non-English articles were excluded. Results: A total of 2037 articles were retrieved, of which only 10 contained quantitative earthquake-related pediatric injury data. All studies were retrospective, had different age categorization, and reported injuries heterogeneously. Only 2 studies reported patterns of injury for all pediatric patients, including patients admitted and discharged. Seven articles described injuries by anatomic location, 5 articles described injuries by type, and 2 articles described injuries using both systems. Conclusions: Differences in age categorization of pediatric patients, and in the injury classification system make quantifying the burden of earthquake-related injuries in the pediatric population difficult. A uniform age categorization and injury classification system are paramount for drawing broader conclusions, enhancing disaster preparation for future disasters, and decreasing morbidity and mortality.

Utilization of outpatient services in refugee settlement health facilities: a comparison by age, gender, and refugee versus host national status

William M. Weiss; Alexander Vu; Hannah Tappis; Sarah Meyer; Christopher Haskew; Paul Spiegel

BackgroundComparisons between refugees receiving health care in settlement-based facilities and persons living in host communities have found that refugees have better health outcomes. However, data that compares utilization of health services between refugees and the host population, and across refugee settlements, countries and regions is limited. The paper will address this information gap. The analysis in this paper uses data from the United Nations High Commissioner of Refugees (UNHCR) Health Information System (HIS).MethodsData about settlement populations and the use of outpatient health services were exported from the UNHCR health information system database. Tableau Desktop was used to explore the data. STATA was used for data cleaning and statistical analysis. Differences in various indicators of the use of health services by region, gender, age groups, and status (host national vs. refugee population) were analyzed for statistical significance using generalized estimating equation models that adjusted for correlated data within refugee settlements over time.ResultsEighty-one refugee settlements were included in this study and an average population of 1.53 million refugees was receiving outpatient health services between 2008 and 2009. The crude utilization rate among refugees is 2.2 visits per person per year across all settlements. The refugee utilization rate in Asia (3.5) was higher than in Africa on average (1.8). Among refugees, females have a statistically significant higher utilization rate than males (2.4 visits per person per year vs. 2.1). The proportion of new outpatient attributable to refugees is higher than that attributable to host nationals. In the Asian settlements, only 2% outpatient visits, on average, were attributable to host community members. By contrast, in Africa, the proportion of new outpatient (OPD) visits by host nationals was 21% on average; in many Ugandan settlements, the proportion of outpatient visits attributable to host community members was higher than that for refugees. There was no statistically significant difference between the size of the male and female populations across refugee settlements. Across all settlements reporting to the UNHCR database, the percent of the refugee population that was less than five years of age is 16% on average.ConclusionsThe availability of a centralized database of health information across UNHCR-supported refugee settlements is a rich resource. The SPHERE standard for emergencies of 1-4 visits per person per year appears to be relevant for Asia in the post-emergency phase, but not for Africa. In Africa, a post-emergency standard of 1-2 visits per person per year should be considered. Although it is often assumed that the size of the female population in refugee settlements is higher than males, we found no statistically significant difference between the size of the male and female populations in refugee settlements overall. Another assumption---that the under-fives make up 20% of the settlement population during the emergency phase---does not appear to hold for the post-emergency phase; under-fives made up about 16% of refugee settlement populations.

Over the past few decades there has been a steady growth in funding for global health, yet generally little is known about funding for global health research. As part of the 2013 Academic Emergency Medicine consensus conference, a session was convened to discuss emergency care research funding in the global health context. Overall, the authors found a lack of evidence available to determine funding priorities or quantify current funding for acute care research in global health. This article summarizes the initial preparatory research and reports on the results of the consensus conference focused on identifying challenges and strategies to improve funding for global emergency care research. The consensus conference meeting led to the creation of near- and long-term goals to strengthen global emergency care research funding and the development of important research questions. The research questions represent a consensus view of important outstanding questions that will assist emergency care researchers to better understand the current funding landscape and bring evidence to the debate on funding priorities of global health and emergency care. The four key areas of focus for researchers are: 1) quantifying funding for global health and emergency care research, 2) understanding current research funding priorities, 3) identifying barriers to emergency care research funding, and 4) using existing data to quantify the need for emergency services and acute care research. This research agenda will enable emergency health care scientists to use evidence when advocating for more funding for emergency care research.
