Improving Accessibility in the Emergency Department for Patients with Disabilities: A Qualitative Study.

INTRODUCTION: The emergency department (ED) is a critical service area for patients living with disabilities in the United States. Despite this, there is limited research on best practices from the patient experience regarding accommodation and accessibility for those with disabilities. In this study we investigate the ED experience from the perspective of patients living with physical and cognitive disability, as well as visual impairment and blindness, to better understand the barriers to accessibility in the ED for these populations. METHODS: Twelve individuals with either physical or cognitive disabilities, visual impairments or blindness were interviewed regarding their ED experiences, particularly related to accessibility. Interviews were transcribed and coded for qualitative analysis with generation of significant themes relating to accessibility in the ED. RESULTS: Major themes from coded analysis were as follows: 1) inadequate communication between staff and patients with visual impairments and physical disabilities; 2) the need for electronic delivery for after-visit summaries for individuals with cognitive and visual disabilities; 3) the importance of mindful listening and patience by healthcare staff; 4) the role of increased hospital support including greeters and volunteers; and 5) comprehensive training with both prehospital and hospital staff around assistive devices and services. CONCLUSION: This study serves as an important first step toward improving the ED environment to ensure accessibility and inclusivity for patients presenting with various types of disabilities. Implementing specific training, policies, and infrastructure changes may improve the experiences and healthcare of this population.

From inequity to access: Evidence-based institutional practices to enhance care for individuals with disabilities.

People with disabilities experience barriers to care in all facets of health care, from engaging with the provider in a clinical setting (attitudinal and communication barriers) to navigating a large institution in a complex health care environment (organizational and environmental barriers), culminating in significant health care disparities. Institutional policy, culture, and physical layout may be inadvertently fostering ableism, which can perpetuate health care inaccessibility and health disparities in the disability community. Here, we present evidence-based interventions at the provider and institutional levels to accommodate patients with hearing, vision, and intellectual disabilities. Institutional barriers can be met with strategies of universal design (i.e., accessible exam rooms and emergency alerts), maximizing electronic medical record accessibility/visibility, and institutional policy development to recognize and reduce discrimination. Barriers at the provider level can be met with dedicated training on care of patients with disabilities and implicit bias training specific to the surrounding patient demographics. Such efforts are crucial to ensuring equitable access to quality care for these patients.

Demographic and risk characteristics of healthcare workers infected with SARS-CoV-2 from two tertiary care hospitals in the United Arab Emirates.

BACKGROUND: Understanding the transmission dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among healthcare workers (HCWs) and their social contacts is crucial to plan appropriate risk-reduction measures. AIM: To analyze the socio-demographic risk factors and transmission of SARS-CoV-2 infection among HCWs in two tertiary care hospitals in Dubai, United Arab Emirates. METHODS: The demographic and clinical characteristics were available for all HCWs in both facilities from the human resources department. A cross-sectional survey was conducted from January-April 2022 among HCWs who tested positive through Reverse Transcriptase Polymerase Chain Reaction of the nasopharyngeal swab for SARS-CoV-2 between March 2020 and August 2021 in two tertiary-level hospitals. The survey included questions on demographics, work profile, characteristics of coronavirus disease 2019 (COVID-19), and infection among their household or co-workers. The survey also checked the knowledge and perception of participants on the infection prevention measures related to SARS-CoV-2. RESULTS: Out of a total of 346 HCWs infected with SARS-CoV-2, 286 (82.7%) HCWs consented to participate in this study. From the sample population, 150 (52.5%) of participants were female, and a majority (230, 80.4%) were frontline HCWs, including 121 nurses (121, 42.4%). Only 48 (16.8%) participants were fully vaccinated at the time of infection. Most infected HCWs (85%) were unaware of any unprotected exposure and were symptomatic at the time of testing (225, 78.7%). Nearly half of the participants (140, 49%) had co-infection among household, and nearly one-third (29.5%) had co-infection among three or more household. Another 108 (37.8%) participants reported cross-infection among co-workers. The frontline HCWs were significantly more infected (25.1% vs 8.6%, P < 0.001) compared to non-frontline HCWs. Another significant risk factor for a high infection rate was male sex (P < 0.001). Among the infected frontline HCWs, a significantly higher proportion were male and shared accommodation with family (P < 0.001). COVID-19 vaccination significantly reduced the infection rate (83.2% vs 16.8, P < 0.001) among HCWs. Most participants (99.3%) were aware about importance of appropriate use of personal protective equipment. However, only 70% agreed with the efficacy of the COVID-19 vaccination in preventing an infection and severe disease. CONCLUSION: The risk profiling of the HCWs infected with SARS-CoV-2 found that working at frontline and being male increase the rate of infection. COVID-19 vaccination can effectively reduce the rate of transmission of SARS-CoV-2 among HCWs.

2021 SAEM Consensus Conference Proceedings: Research Priorities for Developing Emergency Department Screening Tools for Social Risks and Needs.

INTRODUCTION: The Emergency Department (ED) acts as a safety net for our healthcare system. While studies have shown increased prevalence of social risks and needs among ED patients, there are many outstanding questions about the validity and use of social risks and needs screening tools in the ED setting. METHODS: In this paper, we present research gaps and priorities pertaining to social risks and needs screening tools used in the ED, identified through a consensus approach informed by literature review and external expert feedback as part of the 2021 SAEM Consensus Conference -- From Bedside to Policy: Advancing Social Emergency Medicine and Population Health. RESULTS: Four overarching research gaps were identified: (1) Defining the purpose and ethical implications of ED-based screening; (2) Identifying domains of social risks and needs; (3) Developing and validating screening tools; and (4) Defining the patient population and type of screening performed. Furthermore, the following research questions were determined to be of highest priority: (1) What screening tools should be used to identify social risks and needs? (2) Should individual EDs use a national standard screening tools or customized screening tools? (3) What are the most prevalent social risks and needs in the ED? and (4) Which social risks and needs are most amenable to intervention in the ED setting? CONCLUSION: Answering these research questions will facilitate the use of evidence-based social risks and needs screening tools that address knowledge gaps and improve the health of our communities by better understanding the underlying determinants contributing to their presentation and health outcomes.

An exploration of gender-based violence in eastern Myanmar in the context of political transition: findings from a qualitative sexual and reproductive health assessment.

In March 2011, the Myanmar Government transitioned to a nominally civilian parliamentary government, resulting in dramatic increases in international investments and tenuous peace in some regions. In March 2015, Community Partners International, the Women's Refugee Commission, and four community-based organisations (CBOs) assessed community-based sexual and reproductive health (SRH) services in eastern Myanmar amidst the changing political contexts in Myanmar and Thailand. The team conducted 12 focus group discussions among women of reproductive age (18-49 years) with children under five and interviewed 12 health workers in Kayin State, Myanmar. In Mae Sot and Chiang Mai, Thailand, the team interviewed 20 representatives of CBOs serving the border regions. Findings are presented through the socioecological lens to explore gender-based violence (GBV) specifically, to examine continued and emerging issues in the context of the political transition. Cited GBV includes ongoing sexual violence/rape by the military and in the community, trafficking, intimate partner violence, and early marriage. Despite the political transition, women continue to be at risk for military sexual violence, are caught in the burgeoning economic push-pull drivers, and experience ongoing restrictive gender norms, with limited access to SRH services. There is much fluidity, along with many connections and interactions among the contributing variables at all levels of the socioecological model; based on a multisectoral response, continued support for innovative, community-based SRH services that include medical and psychosocial care are imperative for ethnic minority women to gain more agency to freely exercise their SR rights.

Global Emergency Medicine: A Review of the Literature from 2018.

OBJECTIVES: The Global Emergency Medicine Literature Review (GEMLR) conducts a systematic annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most rigorously conducted and widely relevant research in global EM. METHODS: An electronic search of PubMed, a comprehensive retrieval of articles from specific journals, and search of the gray literature were conducted. Title and abstracts retrieved by these searches were screened by a total of 22 reviewers based on their relevance to the field of global EM, across the domains of disaster and humanitarian response (DHR), emergency care in resource-limited settings (ECRLS), and emergency medicine development (EMD). All articles that were deemed relevant by at least one reviewer, their editor, and the managing editor underwent formal scoring of overall methodologic quality and importance to global EM. Two independent reviewers scored all articles; editors provided a third score in cases of widely discrepant scores. RESULTS: A total of 19,102 articles were identified by the searches and, after screening and removal of duplicates, a total of 517 articles underwent full review. Twenty-five percent were categorized as DHR, 61% as ECRLS, and 15% as EMD. Inter-rater reliability testing between the reviewers revealed a Cohen's kappa score of 0.213 when considering the complete score or 0.426 when excluding the more subjective half of the score. A total of 25 articles scored higher than 17.5 of 20; these were selected for a full summary and critique. CONCLUSIONS: In 2018, the total number of articles relevant to global EM that were identified by our search continued to increase. Studies and reviews focusing on pediatric infections, several new and traditionally underrepresented topics, and landscape reviews that may help guide clinical care in new settings represented the majority of top-scoring articles. A shortage of articles related to the development of EM as a specialty was identified.

The Practitioner's Guide to Global Health: an interactive, online, open-access curriculum preparing medical learners for global health experiences.

BACKGROUND: Short-term experiences in global health (STEGH) are increasingly common in medical education, as they can provide learners with opportunities for service, learning, and sharing perspectives. Academic institutions need high-quality preparatory curricula and mentorship to prepare learners for potential challenges in ethics, cultural sensitivity, and personal safety; however, availability and quality of these are variable. OBJECTIVE: The objective of this study is to create and evaluate an open-access, interactive massive open online course (MOOC) that prepares learners to safely and effectively participate in STEGH, permits flexible and asynchronous learning, is free of charge, and provides a certificate upon successful completion. METHODS: Global health experts from 8 countries, 42 institutions, and 7 specialties collaborated to create The Practitioner's Guide to Global Health (PGGH): the first course of this kind on the edX platform. Demographic data, pre- and posttests, and course evaluations were collected and analyzed. RESULTS: Within its first year, PGGH enrolled 5935 learners from 163 countries. In a limited sample of 109 learners, mean posttest scores were significantly improved (p < 0.01). In the course's second year, 213 sampled learners had significant improvement (p < 0.001). CONCLUSION: We created and evaluated the first interactive, asynchronous, free-of-charge global health preparation MOOC. The course has had significant interest from US-based and international learners, and posttest scores have shown significant improvement.

Global Emergency Medicine: A Review of the Literature From 2017.

OBJECTIVES: The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners. METHODS: This year, 17,722 articles written in three languages were identified by our electronic search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. Another two reviewers searched the gray literature, yielding an additional 11 articles. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles. RESULTS: A total of 848 articles met our inclusion criteria and underwent full review. Sixty-three percent were categorized as emergency care in resource-limited settings, 23% as disaster and humanitarian response, and 14% as EM development. Twenty-one articles received scores of 18.5 or higher out of a maximum score 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed a Cohen's kappa of 0.344. CONCLUSIONS: In 2017, the total number of articles identified by our search continued to increase. Studies and reviews with a focus on infectious diseases, pediatrics, and trauma represented the majority of top-scoring articles.

Carotid Flow Time Test Performance for the Detection of Dehydration in Children With Diarrhea.

OBJECTIVES: Unstructured clinical assessments of dehydration in children are inaccurate. Point-of-care ultrasound is a noninvasive diagnostic tool that can help evaluate the volume status; the corrected carotid artery flow time has been shown to predict volume depletion in adults. We sought to determine the ability of the corrected carotid artery flow time to identify dehydration in a population of children presenting with acute diarrhea in Dhaka, Bangladesh. METHODS: Children presenting with acute diarrhea were recruited and rehydrated according to hospital protocols. The corrected carotid artery flow time was measured at the time of presentation. The percentage of weight change with rehydration was used to categorize each child's dehydration as severe (>9%), some (3%-9%), or none (<3%). A receiver operating characteristic curve was constructed to test the performance of the corrected carotid artery flow time for detecting severe dehydration. Linear regression was used to model the relationship between the corrected carotid artery flow time and percentage of dehydration. RESULTS: A total of 350 children (0-60 months) were enrolled. The mean corrected carotid artery flow time was 326 milliseconds (interquartile range, 295-351 milliseconds). The area under the receiver operating characteristic curve for the detection of severe dehydration was 0.51 (95% confidence interval, 0.42, 0.61). Linear regression modeling showed a weak association between the flow time and dehydration. CONCLUSIONS: The corrected carotid artery flow time was a poor predictor of severe dehydration in this population of children with diarrhea.

Global Health and Emergency Care: Defining Clinical Research Priorities.

OBJECTIVES: Despite recent strides in the development of global emergency medicine (EM), the field continues to lag in applying a scientific approach to identifying critical knowledge gaps and advancing evidence-based solutions to clinical and public health problems seen in emergency departments (EDs) worldwide. Here, progress on the global EM research agenda created at the 2013 Academic Emergency Medicine Global Health and Emergency Care Consensus Conference is evaluated and critical areas for future development in emergency care research internationally are identified. METHODS: A retrospective review of all studies compiled in the Global Emergency Medicine Literature Review (GEMLR) database from 2013 through 2015 was conducted. Articles were categorized and analyzed using descriptive quantitative measures and structured data matrices. The Global Emergency Medicine Think Tank Clinical Research Working Group at the Society for Academic Emergency Medicine 2016 Annual Meeting then further conceptualized and defined global EM research priorities utilizing consensus-based decision making. RESULTS: Research trends in global EM research published between 2013 and 2015 show a predominance of observational studies relative to interventional or descriptive studies, with the majority of research conducted in the inpatient setting in comparison to the ED or prehospital setting. Studies on communicable diseases and injury were the most prevalent, with a relative dearth of research on chronic noncommunicable diseases. The Global Emergency Medicine Think Tank Clinical Research Working Group identified conceptual frameworks to define high-impact research priorities, including the traditional approach of using global burden of disease to define priorities and the impact of EM on individual clinical care and public health opportunities. EM research is also described through a population lens approach, including gender, pediatrics, and migrant and refugee health. CONCLUSIONS: Despite recent strides in global EM research and a proliferation of scholarly output in the field, further work is required to advocate for and inform research priorities in global EM. The priorities outlined in this paper aim to guide future research in the field, with the goal of advancing the development of EM worldwide.

Funding global emergency medicine research-from seed grants to NIH support.

BACKGROUND: Funding for global health has grown significantly over the past two decades. Numerous funding opportunities for international development and research work exist; however, they can be difficult to navigate. The 2013 Academic Emergency Medicine consensus conference on global health and emergency care identified the need to strengthen global emergency care research funding, solidify existing funding streams, and expand funding sources. RESULTS: This piece focuses on the various federal funding opportunities available to support emergency physicians conducting international research from seed funding to large institutional grants. In particular, we focus on the application and review processes for the Fulbright and Fogarty programs, National Institutes of Health (NIH) Career development awards, and the Medical Education Partnership Initiative (MEPI), including tips and pathways through each application process. CONCLUSIONS: Lastly, the paper provides an index that may be used as a guide in determining whether the amount of funding provided by a grant is worth the effort in applying.

External validation of the DHAKA score and comparison with the current IMCI algorithm for the assessment of dehydration in children with diarrhoea: a prospective cohort study.

BACKGROUND: Dehydration due to diarrhoea is a leading cause of child death worldwide, yet no clinical tools for assessing dehydration have been validated in resource-limited settings. The Dehydration: Assessing Kids Accurately (DHAKA) score was derived for assessing dehydration in children with diarrhoea in a low-income country setting. In this study, we aimed to externally validate the DHAKA score in a new population of children and compare its accuracy and reliability to the current Integrated Management of Childhood Illness (IMCI) algorithm. METHODS: DHAKA was a prospective cohort study done in children younger than 60 months presenting to the International Centre for Diarrhoeal Disease Research, Bangladesh, with acute diarrhoea (defined by WHO as three or more loose stools per day for less than 14 days). Local nurses assessed children and classified their dehydration status using both the DHAKA score and the IMCI algorithm. Serial weights were obtained and dehydration status was established by percentage weight change with rehydration. We did regression analyses to validate the DHAKA score and compared the accuracy and reliability of the DHAKA score and IMCI algorithm with receiver operator characteristic (ROC) curves and the weighted κ statistic. This study was registered with ClinicalTrials.gov, number NCT02007733. FINDINGS: Between March 22, 2015, and May 15, 2015, 496 patients were included in our primary analyses. On the basis of our criterion standard, 242 (49%) of 496 children had no dehydration, 184 (37%) of 496 had some dehydration, and 70 (14%) of 496 had severe dehydration. In multivariable regression analyses, each 1-point increase in the DHAKA score predicted an increase of 0·6% in the percentage dehydration of the child and increased the odds of both some and severe dehydration by a factor of 1·4. Both the accuracy and reliability of the DHAKA score were significantly greater than those of the IMCI algorithm. INTERPRETATION: The DHAKA score is the first clinical tool for assessing dehydration in children with acute diarrhoea to be externally validated in a low-income country. Further validation studies in a diverse range of settings and paediatric populations are warranted. FUNDING: National Institutes of Health Fogarty International Center.

Accuracy of Inferior Vena Cava Ultrasound for Predicting Dehydration in Children with Acute Diarrhea in Resource-Limited Settings.

INTRODUCTION: Although dehydration from diarrhea is a leading cause of morbidity and mortality in children under five, existing methods of assessing dehydration status in children have limited accuracy. OBJECTIVE: To assess the accuracy of point-of-care ultrasound measurement of the aorta-to-IVC ratio as a predictor of dehydration in children. METHODS: A prospective cohort study of children under five years with acute diarrhea was conducted in the rehydration unit of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b). Ultrasound measurements of aorta-to-IVC ratio and dehydrated weight were obtained on patient arrival. Percent weight change was monitored during rehydration to classify children as having "some dehydration" with weight change 3-9% or "severe dehydration" with weight change > 9%. Logistic regression analysis and Receiver-Operator Characteristic (ROC) curves were used to evaluate the accuracy of aorta-to-IVC ratio as a predictor of dehydration severity. RESULTS: 850 children were enrolled, of which 771 were included in the final analysis. Aorta to IVC ratio was a significant predictor of the percent dehydration in children with acute diarrhea, with each 1-point increase in the aorta to IVC ratio predicting a 1.1% increase in the percent dehydration of the child. However, the area under the ROC curve (0.60), sensitivity (67%), and specificity (49%), for predicting severe dehydration were all poor. CONCLUSIONS: Point-of-care ultrasound of the aorta-to-IVC ratio was statistically associated with volume status, but was not accurate enough to be used as an independent screening tool for dehydration in children under five years presenting with acute diarrhea in a resource-limited setting.

Empirically Derived Dehydration Scoring and Decision Tree Models for Children With Diarrhea: Assessment and Internal Validation in a Prospective Cohort Study in Dhaka, Bangladesh.

INTRODUCTION: Diarrhea remains one of the most common and most deadly conditions affecting children worldwide. Accurately assessing dehydration status is critical to determining treatment course, yet no clinical diagnostic models for dehydration have been empirically derived and validated for use in resource-limited settings. METHODS: In the Dehydration: Assessing Kids Accurately (DHAKA) prospective cohort study, a random sample of children under 5 with acute diarrhea was enrolled between February and June 2014 in Bangladesh. Local nurses assessed children for clinical signs of dehydration on arrival, and then serial weights were obtained as subjects were rehydrated. For each child, the percent weight change with rehydration was used to classify subjects with severe dehydration (>9% weight change), some dehydration (3-9%), or no dehydration (<3%). Clinical variables were then entered into logistic regression and recursive partitioning models to develop the DHAKA Dehydration Score and DHAKA Dehydration Tree, respectively. Models were assessed for their accuracy using the area under their receiver operating characteristic curve (AUC) and for their reliability through repeat clinical exams. Bootstrapping was used to internally validate the models. RESULTS: A total of 850 children were enrolled, with 771 included in the final analysis. Of the 771 children included in the analysis, 11% were classified with severe dehydration, 45% with some dehydration, and 44% with no dehydration. Both the DHAKA Dehydration Score and DHAKA Dehydration Tree had significant AUCs of 0.79 (95% CI = 0.74, 0.84) and 0.76 (95% CI = 0.71, 0.80), respectively, for the diagnosis of severe dehydration. Additionally, the DHAKA Dehydration Score and DHAKA Dehydration Tree had significant positive likelihood ratios of 2.0 (95% CI = 1.8, 2.3) and 2.5 (95% CI = 2.1, 2.8), respectively, and significant negative likelihood ratios of 0.23 (95% CI = 0.13, 0.40) and 0.28 (95% CI = 0.18, 0.44), respectively, for the diagnosis of severe dehydration. Both models demonstrated 90% agreement between independent raters and good reproducibility using bootstrapping. CONCLUSION: This study is the first to empirically derive and internally validate accurate and reliable clinical diagnostic models for dehydration in a resource-limited setting. After external validation, frontline providers may use these new tools to better manage acute diarrhea in children.

Midupper Arm Circumference Outperforms Weight-Based Measures of Nutritional Status in Children with Diarrhea.

BACKGROUND: Undernutrition contributes to 45% of all deaths in children <5 y of age worldwide, with a large proportion of those deaths caused by diarrhea. However, no validated tools exist for assessing undernutrition in children with diarrhea and possible dehydration. OBJECTIVE: This study assessed the validity of different measures of undernutrition in children with diarrhea. METHODS: A prospective cohort study was conducted at an urban hospital in Bangladesh. Children <60 mo of age presenting to the hospital rehydration unit with acute diarrhea were eligible for enrollment. Study staff randomly selected 1196 children for screening, of which 1025 were eligible, 850 were enrolled, and 721 had complete data for analysis. Anthropometric measurements, including weight-for-age z score (WAZ), weight-for-length z score (WLZ), midupper arm circumference (MUAC), and midupper arm circumference z score (MUACZ), were calculated pre- and posthydration in all patients. Measurements were evaluated for their ability to correctly identify undernutrition in children with varying degrees of dehydration. RESULTS: Of the 721 patients with full data for analysis, the median percent dehydration was 4%. Of the 4 measures evaluated, MUAC and MUACZ demonstrated 92-94% agreement pre- and posthydration compared with 69-76% for WAZ and WLZ. Although each 1% change in hydration status was found to change weight-for-age by 0.0895 z scores and weight-for-length by 0.1304 z scores, MUAC and MUACZ were not significantly affected by dehydration status. Weight-based measures misclassified 12% of children with severe underweight and 14% with severe acute malnutrition (SAM) compared with only 1-2% for MUAC and MUACZ. CONCLUSIONS: MUAC and MUACZ were the most accurate predictors of undernutrition in children with diarrhea. WAZ and WLZ were significantly affected by dehydration status, leading to the misdiagnosis of many patients on arrival with severe underweight and SAM. This trial was registered at clinicaltrials.gov as NCT02007733.

Emergency care research funding in the global health context: trends, priorities, and future directions.

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.

Oxygen saturation can predict pediatric pneumonia in a resource-limited setting.

BACKGROUND: The World Health Organization (WHO) recommends using age-specific respiratory rates for diagnosing pneumonia in children. Past studies have evaluated the WHO criteria with mixed results. OBJECTIVE: We examined the accuracy of clinical and laboratory factors for diagnosing pediatric pneumonia in resource-limited settings. METHODS: We conducted a retrospective chart review of children under 5 years of age presenting with respiratory complaints to three rural hospitals in Rwanda who had received a chest radiograph. Data were collected on the presence or absence of 31 historical, clinical, and laboratory signs. Chest radiographs were interpreted by pediatric radiologists as the gold standard for diagnosing pneumonia. Overall correlation and test characteristics were calculated for each categorical variable as compared to the gold standard. For continuous variables, we created receiver operating characteristic (ROC) curves to determine their accuracy for predicting pneumonia. RESULTS: Between May 2011 and April 2012, data were collected from 147 charts of children with respiratory complaints. Approximately 58% of our sample had radiologist-diagnosed pneumonia. Of the categorical variables, a negative blood smear for malaria (χ(2) = 6.21, p = 0.013) and the absence of history of asthma (χ(2) = 4.48, p = 0.034) were statistically associated with pneumonia. Of the continuous variables, only oxygen saturation had a statistically significant area under the ROC curve (AUC) of 0.675 (95% confidence interval [CI] 0.581-0.769 and p = 0.001). Respiratory rate had an AUC of 0.528 (95% CI 0.428-0.627 and p = 0.588). CONCLUSION: Oxygen saturation was the best clinical predictor for pediatric pneumonia and should be further studied in a prospective sample of children with respiratory symptoms in a resource-limited setting.

Using nonrapid HIV technology for routine, opt-out HIV screening in a high-volume urban emergency department.

OBJECTIVE: We implement an opt-out routine screening program in a high-volume, urban emergency department (ED), using conventional (nonrapid) technology as an alternative to rapid HIV tests. METHODS: We performed a retrospective cohort study. Since October 2008, all patients who visited Ben Taub General Hospital ED and had blood drawn were considered eligible for routine opt-out HIV screening. The hospital is a large, publicly funded, urban, academic hospital in Houston, TX. The ED treats approximately 8,000 patients monthly. Screening was performed with standard chemiluminescence technology, batched hourly. Patients with positive screening test results were informed of their likely status, counseled by a service linkage worker, and offered follow-up care at an HIV primary care clinic. Confirmatory Western blot assays were automatically performed on all new HIV-positive samples. RESULTS: Between October 1, 2008, and April 30, 2009, 14,093 HIV tests were performed and 39 patients (0.3%) opted out. Two hundred sixty-two (1.9%) HIV test results were positive and 80 new diagnoses were made, for an incidence of new diagnoses of 0.6%. There were 22 false-positive chemiluminescence results and 7 indeterminate Western blot results. Nearly half the patients who received a new diagnosis were not successfully linked to HIV care in our system. CONCLUSION: Opt-out screening using standard nonrapid technology, rather than rapid testing, is feasible in a busy urban ED. This method of HIV screening has cost benefits and a low false-positivity rate, but aggressive follow-up and referral of patients with new diagnoses for linkage to care is required.
