Epidemiology of burns in a humanitarian setting: A national study among refugees in Lebanon

INTRODUCTION

Burns represent one of the leading causes of morbidity worldwide and disproportionately impact women, children, and socioeconomically disadvantaged individuals. Syrian refugees who fled conflict to land in overcrowded informal settlements across Lebanon are a particularly vulnerable population. This study aims to assess the etiology and risk factors for burns in this population.

METHODS

This cross-sectional, cluster-based population study adopted the Surgeons Overseas Assessment of Surgical Need (SOSAS) version 3.0 to capture data from refugees residing in informal settlements in multiple regions across Lebanon. The tool was contextualized and used to collect detailed information on burn cases sustained by refugees during the last 12 months prior to data collection. Univariate logistic regression models were performed to assess the relationship between burns and associated risk factors.

RESULTS

From the 1468 households surveyed, a total of 223 households experienced a burn in the last 12 months. Over 63% of burns occurred in children under the age of ten years and almost 57% of burns occurred in females. More than 70% of burns resulted from hot liquid, while 17% were caused by direct heat contact. Over 3/4ths of burns occurred while preparing food (77.4%). Approximately 32% of those burned did not seek healthcare, of which almost 85% noted the cause was mainly due to financial limitations.

CONCLUSION

Burns are a common injury in the Syrian refugee population living in Lebanon. Children and women are particularly impacted, often during cooking. Multi-level interventions are necessary to reduce burn injuries and improve care for those affected by burns. Community kitchens can be used to separate cooking and living environments and get stoves and hot liquids off the floor. Importantly, policies should allow for refugees to receive medical care when necessary without a major financial burden.

Damage to medical complexes in the Israel-Hamas war: a geospatial analysis

INTRODUCTION

Medical facilities are civilian objects specially protected during armed conflict by international humanitarian law (IHL). These protections are customarily applied regardless of the conflict, parties or contexts involved. Attacks on medical care have characterised the bombardment campaign of the Gaza Strip beginning 7 October 2023. This study presents evidence regarding patterns of damage to medical complexes relative to all other buildings in the first month of this conflict.

METHODS

This is an observational pre/post-study of damage to buildings during the first month of the Israel Defence Force bombardment of Gaza from 7 October to 7 November 2023. Open-source polygons for the Gaza Strip were spatially joined with building damage assessments from satellite imagery analysis. Medical facilities were included in the analysis if they were cross-referenced by a minimum of two datasets. Welch's t-test was used to test for statistically significant differences in the proportions of damaged medical complexes and other buildings.

RESULTS

A total of 167 292 unique buildings were identified, including 106 cross-referenced medical complexes. Approximately 9% of non-medical buildings and medical complexes alike sustained damage during the first month of the bombardment (p>0.7292).

CONCLUSION

During the first month of the bombing campaign, evidence suggests medical complexes have not received special protection as required by IHL. This finding raises concerns about combatants' application of the principles of distinction, proportionality and precaution, suggesting the importance of further investigation.

Health services access, utilization, and barriers for Arabic-speaking refugees resettled in Connecticut, USA

BACKGROUND

Arabic-speaking refugees are the largest group of refugees arriving in the United States since 2008, yet little is known about their rates of healthcare access, utilization, and satisfaction after the end of the Refugee Medical Assistance (RMA) period.

METHODS

This study was a cross-sectional observational study. From January to December 2019, a household survey was conducted of newly arrived Arabic-speaking refugees in Connecticut between 2016 and 2018. Households were interviewed in Arabic either in person or over the phone by one of five researchers. Descriptive statistics were generated for information collected on demographics, prevalence of chronic conditions, patterns of health seeking behavior, insurance status and patient satisfaction using the Patient Satisfaction Questionnaire (PSQ-18).

RESULTS

Sixty-five households responded to the survey representing 295 Arabic-speaking refugees - of which 141 (48%) were children. Forty-seven households (72%) reported 142 chronic medical conditions among 295 individuals, 62 persons (21%) needed daily medication, 285 (97%) persons were insured. Median patient satisfaction was > 4.0 out of 5 for 6 of 7 domains of the PSQ-18 but wide variation (scores from 1.0 - 5.0).

CONCLUSION

Arabic-speaking refugees in Connecticut participating in this study were young. The majority remained insured after their Refugee Medical Assistance lapsed. They expressed median high satisfaction with health services but with wide variation. Inaccessibility of health services in Arabic and difficulty obtaining medications remain areas in need of improvement.

Factors impacting trauma-specific quality of life following injury: A multi-center assessment in Lebanon

OBJECTIVE

Injuries account for a large portion of the global burden of disease, representing over 10% of all disability adjusted life years (DALYs). This study analyzes the economic impact of injury for those experiencing moderate-to-severe injury in Beirut, Lebanon. It further examines the impact of different demographic and socioeconomic factors on trauma-specific quality of life 1-2 years following injury.

METHODS

This was a prospective cohort study following patients 1-2 years after being treated for injury at one of three hospitals in Beirut, Lebanon. Patients interviewed by phone. In addition to questions on financial impact, access to healthcare, and socioeconomic status, the Trauma-specific Quality of Life (TQoL) Questionnaire was used to assess quality of life following injury. Multivariable linear models were constructed to examine TQoL and demographics among institutes.

RESULTS

116 patients completed interviews. The average out-of-pocket cost of injury was 2975.42 USD, 65% of which was borrowed. 21% of people lost employment due to injury. Patients at Geitawi Hospital and the Rafic Hariri Governmental Hospital borrowed more on average and had higher reductions in employment than patients at the American University of Beirut Medical Center (AUBMC). There was a loss of income for those employed at the time of injury, with a mean monthly loss of 261.6 USD. The economic impact of injury was 10,329.00 USD. 25% of patients reported difficulty with accessing follow-up care, predominantly due to cost. Mean-adjusted Trauma-specific Quality of life (TQoL) was highest at AUBMC. Education was associated with functional recovery in the TQoL questionnaire; for every additional year of education there was an increase in the functional recovery domain of 0.03.

CONCLUSION

Individuals that experienced moderate-to-severe injury in Beirut, Lebanon, suffered financial repercussions, including reductions in income, less employment, or unemployment. Across all patients surveyed, higher level of education was associated with better functional quality of life. More study into the intricacies of accessing healthcare care in Lebanon, especially given the current economic and political climate, are crucial to maintain the health of those experiencing injury and can help inform targeted interventions.

Household economic impact of road traffic injury versus routine emergencies in a low-income country

INTRODUCTION

Road traffic injuries (RTIs) are increasing and have disproportionate impact on residents of low- and middle-income countries (LMICs) where 90% of deaths occur. RTIs are a leading cause of death for those aged 15 - 29 years with costs estimated to be up to 3% of GDP. Despite this fact, little primary research has been done on the household economic impact of these events.

METHODS

From July to October 2016, 860 consecutive emergency department patients were enrolled and followed up at 6-8 weeks to assess the household financial impacts of these emergency presentations. At follow-up, patients were queried regarding health status, lost wages or schooling, household costs incurred due to their injury or illness, and assets sold.

RESULTS

860 patients were enrolled and 675 patients (78%) completed follow-up surveys. Of those, 660 had a confirmed reason for visit - 303 (45%) road traffic injuries, 357 (53%) other emergency presentations (non-RTI) - encompassing medical presentations and other types of injury, and reason for visit was missing for 15 patients (2%). More than 90% of RTI patients were working or in school prior to their injury. In the economically productive ages (15-44 years) RTI predominated (70%) vs non-RTI (39%). RTI patients were more likely to report residual disability (78.2% RTI vs 68.1% non-RTI, p=0.004). All emergency patients reported difficulty paying for basic needs (food, housing and medical expenses). More than ⅓ of emergency patients reported having to sell assets in order to meet basic needs after their illness or injury. Despite similar hospital costs and fewer lost days of work for both patients and caregivers, the mean financial impact on households of RTI patients was 37% more than for non-RTI patients. These costs equalled between 6-16 weeks of income for patients based on their occupation type and median reported pre-hospitalization income.

DISCUSSION

Ugandan emergency care patients suffered significant personal and household economic hardship. In addition to the need for policy and infrastructural changes to improve road safety, these findings highlight the need for basic emergency care systems to secure economic gains in vulnerable households and prevent medical impoverishment of marginal communities.

Impact of nursing education and a monitoring tool on outcomes in traumatic brain injury

Introduction

Throughout the world, traumatic brain injury (TBI) is one of the leading causes of morbidity and mortality. Low-and middle-income countries experience an especially high burden of TBI. While guidelines for TBI management exist in high income countries, little is known about the optimal management of TBI in low resource settings. Prevention of secondary injuries is feasible in these settings and has potential to improve mortality.

Methods

A pragmatic quasi-experimental study was conducted in the emergency centre (EC) of Mulago National Referral Hospital to evaluate the impact of TBI nursing education and use of a monitoring tool on mortality. Over 24 months, data was collected on 541 patients with moderate (GCS9-13) to severe (GCS≤8) TBI. The primary outcome was in-hospital mortality and secondary outcomes included time to imaging, time to surgical intervention, time to advanced airway, length of stay and number of vital signs recorded.

Results

Data were collected on 286 patients before the intervention and 255 after. Unadjusted mortality was higher in the post-intervention group but appeared to be related to severity of TBI, not the intervention itself. Apart from number of vital signs, secondary outcomes did not differ significantly between groups. In the post-intervention group, vital signs were recorded an average of 2.85 times compared to 0.49 in the pre-intervention group (95% CI 2.08-2.62, p ≤ 0.001). The median time interval between vital signs in the post-intervention group was 4.5 h (IQR 2.1-10.6).

Conclusion

Monitoring of vital signs in the EC improved with nursing education and use of a monitoring tool, however, there was no detectable impact on mortality. The high mortality among patients with TBI underscores the need for treatment strategies that can be implemented in low resource settings. Promising approaches include improved monitoring, organized trauma systems and protocols with an emphasis on early aggressive care and primary prevention.

Defining High-risk Emergency Chief Complaints: Data-driven Triage for Low- and Middle-income Countries

OBJECTIVES

Emergency medicine in low- and middle-income countries (LMICs) is hindered by lack of research into patient outcomes. Chief complaints (CCs) are fundamental to emergency care but have only recently been uniquely codified for an LMIC setting in Uganda. It is not known whether CCs independently predict emergency unit patient outcomes.

METHODS

Patient data collected in a Ugandan emergency unit between 2009 and 2018 were randomized into validation and derivation data sets. A recursive partitioning algorithm stratified CCs by 3-day mortality risk in each group. The process was repeated in 10,000 bootstrap samples to create an averaged risk ranking. Based on this ranking, CCs were categorized as "high-risk" (>2× baseline mortality), "medium-risk" (between 2 and 0.5× baseline mortality), and "low-risk" (<0.5× baseline mortality). Risk categories were then included in a logistic regression model to determine if CCs independently predicted 3-day mortality.

RESULTS

Overall, the derivation data set included 21,953 individuals with 7,313 in the validation data set. In total, 43 complaints were categorized, and 12 CCs were identified as high-risk. When controlled for triage data including age, sex, HIV status, vital signs, level of consciousness, and number of complaints, high-risk CCs significantly increased 3-day mortality odds ratio (OR = 2.39, 95% confidence interval [CI] = 1.95 to 2.93, p < 0.001) while low-risk CCs significantly decreased 3-day mortality odds (OR = 0.16, 95% CI = 0.09 to 0.29, p < 0.001).

CONCLUSIONS

High-risk CCs were identified and found to predict increased 3-day mortality independent of vital signs and other data available at triage. This list can be used to expand local triage systems and inform emergency training programs. The methodology can be reproduced in other LMIC settings to reflect their local disease patterns.

Non-operative management of blunt abdominal solid organ trauma in adult patients

INTRODUCTION

Despite agreement in the literature that "stable" blunt trauma patients may be managed conservatively, in Egypt many such patients receive operative management. This paper presents the results of a pragmatic, prospective, observational study to evaluate outcomes of non-operative (NOP) versus operative (OP) management of blunt abdominal solid organ trauma in hemodynamically stable adults admitted to Tanta University Emergency Hospital (TUH) in Egypt.

METHODS

A prospective observational study enrolled adult blunt abdominal trauma patients with solid organ injury at TUH over a 3-year period (June 2014-June 2017). Inclusion criteria were age ≥18 yr, mean arterial pressure >65 mm Hg, heart rate <110 bpm, hematocrit ≥7 mg/dl, and abdominal organ injury diagnosed by ultrasound or computed tomography (CT). Excluded patients were those with pelvis and femur fractures; patients with penetrating abdominal trauma; predominate burn injuries, children and pregnant women. All patients were assigned to non-operative or operative management based on clinician preference. Outcomes of interest were 30-day mortality, blood transfusion volume, and length of stay. Descriptive statistics and χ2 were used to compare outcomes.

RESULTS

During the study period, 4254 trauma patients presented to TUH. Of these, 790 had blunt abdominal trauma and 111 (14.1%) met inclusion criteria. Injury severity scores for each group were comparable (24 ± 10 - NOP vs. 28 ± 11 - OP, p = 0.126). NOP received less transfused blood (213.41 ± 360.3 ml [NOP] vs.1155.17 ± 380.4 ml [OP] (p < 0.0001)) but had a longer length of stay (8.29 ± 2.8 [NOP] vs. 6.45 ± 1.97 days [OP] (p = 0.012)). There was no difference in mortality between groups (p = 0.091).

CONCLUSION

Our study demonstrated that non-operative management in Egypt of blunt abdominal trauma was safe and resulted in fewer procedures, fewer units of blood transfused, and no increase in mortality. Longer length of stay for non-operative patients might reflect treating physician caution in their management.

Leveraging the COVID-19 response to improve emergency care systems in the Eastern Mediterranean Region

The COVID-19 pandemic began as a cluster of reported cases of acute respiratory illness in China on 31 December 2019 and went on to spread with exponential growth across the globe. By the time it was characterized as a global pandemic on 11 March 2020, 17 of 22 countries in the Eastern Mediterranean Region (EMR) had reports of infected persons. EMR countries are particularly susceptible to such outbreaks due to the presence of globally interconnected markets; complex emergencies in more than half of the countries; religious mass gatherings that draw tens of millions of pilgrims annually; and variation in emergency care systems capacity and health systems performance within and between countries.

Emergency care surveillance and emergency care registries in low-income and middle-income countries: conceptual challenges and future directions for research

Despite the fact that the 15 leading causes of global deaths and disability-adjusted life years are from conditions amenable to emergency care, and that this burden is highest in low-income and middle-income countries (LMICs), there is a paucity of research on LMIC emergency care to guide policy making, resource allocation and service provision. A literature review of the 550 articles on LMIC emergency care published in the 10-year period from 2007 to 2016 yielded 106 articles for LMIC emergency care surveillance and registry research. Few articles were from established longitudinal surveillance or registries and primarily composed of short-term data collection. Using these articles, a working group was convened by the US National Institutes of Health Fogarty International Center to discuss challenges and potential solutions for established systems to better understand global emergency care in LMICs. The working group focused on potential uses for emergency care surveillance and registry data to improve the quality of services provided to patients. Challenges included a lack of dedicated resources for such research in LMIC settings as well as over-reliance on facility-based data collection without known correlation to the overall burden of emergency conditions in the broader community. The group outlined potential solutions including incorporating data from sources beyond traditional health records, use of standard clinical forms that embed data needed for research and policy making and structured population-based research to establish clear linkages between what is seen in emergency units and the wider community. The group then identified current gaps in LMIC emergency care surveillance and registry research to form a research agenda for the future.

Devastating neurologic injuries in the Syrian war

Background

Since 2011, hundreds of thousands of Syrians have been displaced and injured due to the ongoing Syrian civil war. In this study, we report the prevalence of neurologic injuries in a major rehabilitation center on the Turkish-Syrian border where death and injury tolls continue to rise.

Method

Based on several on-site visits from 2013 to 2016, medical practitioners collected data from patients in the major rehabilitation center on the border of Turkey and Syria. The clinical data, which included the type and cause of injury, laterality, paralysis, areas injured, and treatment offered, were analyzed.

Results

A total of 230 patients were identified as having sustained a neurologic injury, 221/230 (96.1%) male and 9/230 (3.91%) female, ranging from ages 2-52 years. A total of 305 total injuries were documented over the course of a 4-year analysis due to several patients having multiple injuries. Gunshot wounds were the dominant mechanism of injury in 125/230 (54.3%) patients. Patients more frequently sustained single injuries 152/230 (66.1%) than multiple injuries 78/230 (33.9%). Peripheral nerve injuries were the most prevalent injuries, at 92.5% of all neurologic injuries (282/305), specifically injury to the radial nerve, at 19.1% (54/282) of peripheral injuries. Patients with spinal cord injuries made up 20/230 (8.7%) of all patients, with thoracic spine injuries composing 50% (10/20). Traumatic brain injuries were the least prevalent, 3/230 (1.3%), with an equal distribution of subtypes.

Conclusion

This study and critical analysis of the devastation in Syria suggests the desperate need for emergency aid.

Derivation and validation of a chief complaint shortlist for unscheduled acute and emergency care in Uganda

OBJECTIVES

Derive and validate a shortlist of chief complaints to describe unscheduled acute and emergency care in Uganda.

SETTING

A single, private, not-for profit hospital in rural, southwestern Uganda.

PARTICIPANTS

From 2009 to 2015, 26 996 patient visits produced 42 566 total chief complaints for the derivation dataset, and from 2015 to 2017, 10 068 visits produced 20 165 total chief complaints for the validation dataset.

METHODS

A retrospective review of an emergency centre quality assurance database was performed. Data were abstracted, cleaned and refined using language processing in Stata to produce a longlist of chief complaints, which was collapsed via a consensus process to produce a shortlist and turned into a web-based tool. This tool was used by two local Ugandan emergency care practitioners to categorise complaints from a second longlist produced from a separate validation dataset from the same study site. Their agreement on grouping was analysed using Cohen's kappa to determine inter-rater reliability. The chief complaints describing 80% of patient visits from automated and consensus shortlists were combined to form a candidate chief complaint shortlist.

RESULTS

Automated data cleaning and refining recognised 95.8% of all complaints and produced a longlist of 555 chief complaints. The consensus process yielded a shortlist of 83 grouped chief complaints. The second validation dataset was reduced in Stata to a longlist of 451 complaints. Using the shortlist tool to categorise complaints produced 71.5% agreement, yielding a kappa of 0.70 showing substantial inter-rater reliability. Only one complaint did not fit into the shortlist and required a free-text amendment. The two shortlists were identical for the most common 14 complaints and combined to form a candidate list of 24 complaints that could characterise over 80% of all emergency centre chief complaints.

CONCLUSIONS

Shortlists of chief complaints can be generated to improve standardisation of data entry, facilitate research efforts and be employed for paper chart usage.

A qualitative study exploring nurses' attitudes, confidence, and perceived barriers to implementing a traumatic brain injury nursing chart in Uganda

Introduction

In Africa, traumatic brain injuries frequently result from road traffic injuries and assaults. Despite limited resources and the high costs of life-saving neurosurgical interventions, secondary brain injury prevention has the potential for improving outcomes. However, nurses and other medical personnel infrequently monitor vital signs, blood sugar, and pulse oximetry and only sporadically re-assess neurological status.

Methods

In one-on-one, semi-structured interviews, 27 nurses from Mulago Hospital’s emergency centre, a tertiary care trauma hospital in Kampala, Uganda, provided feedback regarding a traumatic brain injury-focused education session and use of a nursing chart for detecting secondary brain injury. The interviews explored the nurses’ confidence and perceived barriers to long-term chart implementation and traumatic brain injury care, as well as their ideas for improving this intervention. Interviews were audio recorded, transcribed, and coded using ATLAS.ti: Qualitative Data Analysis and Research Software (Cleverbridge, Inc., Chicago, USA) and Microsoft Word and Excel (Microsoft Office, Redmond, USA) for thematic content analysis.

Results

Key findings identified in the interviews included the nurses’ attitudes toward the chart and their feelings of increased confidence in assessing and caring for these patients. The main barriers to continuous implementation included inadequate staffing and resources.

Conclusion

Nurses were receptive to the education session and nursing chart, and felt that it increased their confidence and improved their ability to care for traumatic brain injured patients. However, lack of supplies, overwhelming numbers of patients, and inadequate staffing interfered with consistent monitoring of patients. The nurses offered various suggestions for improving traumatic brain injury care that should be further investigated. More research is needed to assess the applicability of a standardised traumatic brain injury nursing education and chart in a broader context.

Analysis of Prehospital Transport Use for Trauma Patients in Lusaka, Zambia

Despite an increasing burden of injuries, prehospital transport systems remain underdeveloped in many low- and middle-income countries. Little information exists on the use of prehospital services for trauma patients in Zambia.

METHOD

A prospective, observational study of trauma presentations was undertaken for 6 months in Lusaka, Zambia, to establish the epidemiology and outcomes of injury in the region. In addition to demographics and mechanism of injury, data were collected on prehospital transport as well as inpatient resources utilization. Trained study personnel gathered data on trauma presentations 24 h a day. Statistical analysis was conducted using SAS 9.3 from a Microsoft^® Access database.

RESULTS

3498 trauma patients were enrolled in the study on arrival to University Teaching Hospital (UTH). 3264 patients had a transport means recorded (95.3 %). Two-thirds (66 %) arrived within 6 h of injury, and 23 % arrived within the first hour after injury. A majority arrived by private vehicle (53.4 %) or public transport (37.7 %); only 5.9 % were transported by public or private ambulance. Of those arriving within the first hour after injury, 69.1 % came by private car, 24.6 % by public transport and 3.1 % by ambulance. There was a small statistical increase in Kampala Trauma Score II among ambulance arrivals.

CONCLUSION

Trauma patient use a variety of transport methods to get to UTH. A majority of patients use no formal ambulance transport. Despite this fact, a majority arrives within 6 h of injury but receive no formal prehospital care. An integrated, multilayered prehospital care and transport system may be the most effective approach for Zambia.

Obesity as a form of malnutrition: over-nutrition on the Uganda "malnutrition" agenda

The objectives were to highlight the burden of overweight and obesity as an additional area of importance for the malnutrition agenda in Uganda and to provide evidence-based considerations for stakeholders involved. Introduction: Mirroring other Low- and Middle-Income Countries (LMICs), Uganda is experiencing a “double burden” of over-nutrition related issues - both obesity and overweight, and related non-communicable diseases (NCDs) alongside the under-nutrition that has long plagued the country. Despite the commonplace assumption that under-nutrition is the predominant form of malnutrition in Uganda, we explore recent literature that in fact, challenges this notion. While food insecurity has contributed to the under-nutrition problem, a lack of dietary diversity also has a demonstrated role in increasing over-nutrition. We cannot afford to ignore over-nutrition concomitant with stunting and wasting in the country. Increase in the burden of this less acknowledged form of malnutrition in Uganda is critical to investigate, and yet poorly understood. A move towards increased regionally targeted over-nutrition research, funding, government prioritization and advocacy is needed.

Results of a Nationwide Capacity Survey of Hospitals Providing Trauma Care in War-Affected Syria

IMPORTANCE

The Syrian civil war has resulted in large-scale devastation of Syria's health infrastructure along with widespread injuries and death from trauma. The capacity of Syrian trauma hospitals is not well characterized. Data are needed to allocate resources for trauma care to the population remaining in Syria.

OBJECTIVE

To identify the number of trauma hospitals operating in Syria and to delineate their capacities.

DESIGN, SETTING, AND PARTICIPANTS

From February 1 to March 31, 2015, a nationwide survey of 94 trauma hospitals was conducted inside Syria, representing a coverage rate of 69% to 93% of reported hospitals in nongovernment controlled areas.

MAIN OUTCOMES

Identification and geocoding of trauma and essential surgical services in Syria.

RESULTS

Although 86 hospitals (91%) reported capacity to perform emergency surgery, 1 in 6 hospitals (16%) reported having no inpatient ward for patients after surgery. Sixty-three hospitals (70%) could transfuse whole blood but only 7 (7.4%) could separate and bank blood products. Seventy-one hospitals (76%) had any pharmacy services. Only 10 (11%) could provide renal replacement therapy, and only 18 (20%) provided any form of rehabilitative services. Syrian hospitals are isolated, with 24 (26%) relying on smuggling routes to refer patients to other hospitals and 47 hospitals (50%) reporting domestic supply lines that were never open or open less than daily. There were 538 surgeons, 378 physicians, and 1444 nurses identified in this survey, yielding a nurse to physician ratio of 1.8:1. Only 74 hospitals (79%) reported any salary support for staff, and 84 (89%) reported material support. There is an unmet need for biomedical engineering support in Syrian trauma hospitals, with 12 fixed x-ray machines (23%), 11 portable x-ray machines (13%), 13 computed tomographic scanners (22%), 21 adult (21%) and 5 pediatric (19%) ventilators, 14 anesthesia machines (10%), and 116 oxygen cylinders (15%) not functional. No functioning computed tomographic scanners remain in Aleppo, and 95 oxygen cylinders (42%) in rural Damascus are not functioning despite the high density of hospitals and patients in both provinces.

CONCLUSIONS AND RELEVANCE

Syrian trauma hospitals operate in the Syrian civil war under severe material and human resource constraints. Attention must be paid to providing biomedical engineering support and to directing resources to currently unsupported and geographically isolated critical access surgical hospitals.

Developing metrics for emergency care research in low- and middle-income countries

INTRODUCTION

There is little research on emergency care delivery in low- and middle-income countries (LMICs). To facilitate future research, we aimed to assess the set of key metrics currently used by researchers in these settings and to propose a set of standard metrics to facilitate future research.

METHODS

Systematic literature review of 43,109 published reports on general emergency care from 139 LMICs. Studies describing care for subsets of emergency conditions, subsets of populations, and data aggregated across multiple facilities were excluded. All facility- and patient-level statistics reported in these studies were recorded and the most commonly used metrics were identified.

RESULTS

We identified 195 studies on emergency care delivery in LMICs. There was little uniformity in either patient- or facility-level metrics reported. Patient demographics were inconsistently reported: only 33% noted average age and 63% the gender breakdown. The upper age boundary used for paediatric data varied widely, from 5 to 20 years of age. Emergency centre capacity was reported using a variety of metrics including annual patient volume (n = 175, 90%); bed count (n = 60, 31%), number of rooms (n = 48, 25%); frequently none of these metrics were reported (n = 16, 8%). Many characteristics essential to describe capabilities and performance of emergency care were not reported, including use and type of triage; level of provider training; admission rate; time to evaluation; and length of EC stay.

CONCLUSION

We found considerable heterogeneity in reporting practices for studies of emergency care in LMICs. Standardised metrics could facilitate future analysis and interpretation of such studies, and expand the ability to generalise and compare findings across emergency care settings.

Prediction of In-hospital Mortality in Emergency Department Patients With Sepsis: A Local Big Data-Driven, Machine Learning Approach

OBJECTIVES

Predictive analytics in emergency care has mostly been limited to the use of clinical decision rules (CDRs) in the form of simple heuristics and scoring systems. In the development of CDRs, limitations in analytic methods and concerns with usability have generally constrained models to a preselected small set of variables judged to be clinically relevant and to rules that are easily calculated. Furthermore, CDRs frequently suffer from questions of generalizability, take years to develop, and lack the ability to be updated as new information becomes available. Newer analytic and machine learning techniques capable of harnessing the large number of variables that are already available through electronic health records (EHRs) may better predict patient outcomes and facilitate automation and deployment within clinical decision support systems. In this proof-of-concept study, a local, big data-driven, machine learning approach is compared to existing CDRs and traditional analytic methods using the prediction of sepsis in-hospital mortality as the use case.

METHODS

This was a retrospective study of adult ED visits admitted to the hospital meeting criteria for sepsis from October 2013 to October 2014. Sepsis was defined as meeting criteria for systemic inflammatory response syndrome with an infectious admitting diagnosis in the ED. ED visits were randomly partitioned into an 80%/20% split for training and validation. A random forest model (machine learning approach) was constructed using over 500 clinical variables from data available within the EHRs of four hospitals to predict in-hospital mortality. The machine learning prediction model was then compared to a classification and regression tree (CART) model, logistic regression model, and previously developed prediction tools on the validation data set using area under the receiver operating characteristic curve (AUC) and chi-square statistics.

RESULTS

There were 5,278 visits among 4,676 unique patients who met criteria for sepsis. Of the 4,222 patients in the training group, 210 (5.0%) died during hospitalization, and of the 1,056 patients in the validation group, 50 (4.7%) died during hospitalization. The AUCs with 95% confidence intervals (CIs) for the different models were as follows: random forest model, 0.86 (95% CI = 0.82 to 0.90); CART model, 0.69 (95% CI = 0.62 to 0.77); logistic regression model, 0.76 (95% CI = 0.69 to 0.82); CURB-65, 0.73 (95% CI = 0.67 to 0.80); MEDS, 0.71 (95% CI = 0.63 to 0.77); and mREMS, 0.72 (95% CI = 0.65 to 0.79). The random forest model AUC was statistically different from all other models (p ≤ 0.003 for all comparisons).

CONCLUSIONS

In this proof-of-concept study, a local big data-driven, machine learning approach outperformed existing CDRs as well as traditional analytic techniques for predicting in-hospital mortality of ED patients with sepsis. Future research should prospectively evaluate the effectiveness of this approach and whether it translates into improved clinical outcomes for high-risk sepsis patients. The methods developed serve as an example of a new model for predictive analytics in emergency care that can be automated, applied to other clinical outcomes of interest, and deployed in EHRs to enable locally relevant clinical predictions.

Academic affairs and global health: how global health electives can accelerate progress towards ACGME milestones

Global health electives (GHEs) have become a standard offering in many residency programs. Residency electives should aid residents in achieving outcomes in the Accreditation Council for Graduate Medical Education (ACGME) competency domains. In this paper, the authors review existing literature and provide expert opinion to highlight how global health electives can complement traditional training programs to assist residents in achieving ACGME milestones, using emergency medicine residency as an example. Recommendations are provided for identifying exemplary global health electives and for the development of institutional global health elective curricula in order to facilitate milestone achievement. Global health electives can advance progress towards ACGME milestones; however, they may vary greatly in terms of potential for learner advancement. Electives should thus be rigorously vetted to ensure they meet standards that will facilitate this process. Given that milestones are a newly introduced tool for assessing resident educational achievement, very little research is available currently to directly determine impacts, and further study will be needed.

Survey of point of care ultrasound usage in emergency medicine by Vietnamese physicians

OBJECTIVES

Emergency medicine (EM) is rapidly developing as a specialty in Vietnam. Point of care ultrasound (POCUS) is currently taught as part of formal EM curriculums though limited literature exists to describe current POCUS usage in EDs in Vietnam. A survey was developed to understand current POCUS utilisation and guide future training efforts.

METHODS

A survey was administered to 104 Vietnamese physicians attending a national emergency medicine symposium regarding POCUS utilisation, access, training and preference. Data were analysed using multiple logistic regression to identify independent variables associated with POCUS usage.

RESULTS

Increased access to ultrasound machines was significantly associated with increased POCUS usage, with 'all the time' access (OR = 92.9, 95% CI 7.15-1207.6, P = 0.001) being more strongly associated than 'sometimes' access (OR = 41.4, 95% CI 4.08-419.8, P = 0.002). Formal training did not significantly increase POCUS usage and 50.0% of respondents who regularly used POCUS had no formal training. There was no significant difference in physician preference or comfort for any single application of POCUS. There were 98.0% of trainees and 96.3% of independently practising physicians who reported a desire for additional POCUS training.

CONCLUSIONS

Regular access to ultrasound machines increases the frequency of POCUS usage in EDs in Vietnam. POCUS training was not as clearly associated with POCUS usage as those without formal training were equally likely to use POCUS as those with formal training. No single POCUS application stood out as strongly preferred by physicians in this survey.

Research priorities for data collection and management within global acute and emergency care systems

Barriers to global emergency care development include a critical lack of data in several areas, including limited documentation of the acute disease burden, lack of agreement on essential components of acute care systems, and a lack of consensus on key analytic elements, such as diagnostic classification schemes and regionally appropriate metrics for impact evaluation. These data gaps obscure the profound health effects of lack of emergency care access in low- and middle-income countries (LMICs). As part of the Academic Emergency Medicine consensus conference "Global Health and Emergency Care: A Research Agenda," a breakout group sought to develop a priority research agenda for data collection and management within global emergency care systems.

Making recording and analysis of chief complaint a priority for global emergency care research in low-income countries

The chief complaint is a patient's self-reported primary reason for presenting for medical care. The clinical utility and analytical importance of recording chief complaints have been widely accepted in highly developed emergency care systems, but this practice is far from universal in global emergency care, especially in limited-resource areas. It is precisely in these settings, however, that the use of chief complaints may have particular benefit. Chief complaints may be used to quantify, analyze, and plan for emergency care and provide valuable information on acute care needs where there are crucial data gaps. Globally, much work has been done to establish local practices around chief complaint collection and use, but no standards have been established and little work has been done to identify minimum effective sets of chief complaints that may be used in limited-resource settings. As part of the Academic Emergency Medicine consensus conference, "Global Health and Emergency Care: A Research Agenda," the breakout group on data management identified the lack of research on emergency chief complaints globally-especially in low-income countries where the highest proportion of the world's population resides-as a major gap in global emergency care research. This article reviews global research on emergency chief complaints in high-income countries with developed emergency care systems and sets forth an agenda for future research on chief complaints in limited-resource settings.

Impacts of natural hazards on primary health care facilities of iran: a 10-year retrospective survey

Public health facilities in Iran are exposed to a wide range of natural hazards. This article presents the first survey of the impacts of such natural hazards on primary health care (PHC) centers in Iran from 2001 to 2011. A retrospective survey was conducted in 25 out of 30 provinces of Iran. Archival reports at provincial public health departments were cross-referenced with key informant interviews. During a 10-year period, 119 natural hazard events were recorded that led to physical damage and/or functional failure in 1,401 health centers, 127 deaths and injury or illness in 644 health staff. Earthquakes accounted for the most physical damage and all health-worker deaths. However, there was an increasing trend of impacts due to hydro-meteorological hazards. Iran’s health system needs to establish a registry to track the impact of natural hazards on health facilities, conduct regular hazard and vulnerability assessments and increase mitigation and preparedness measures.

School fire in Iran: simple actions save lives

On December 5, 2012 a fire broke out in a primary school in Iran, causing injuries to 26 children and two deaths. The fire came from an oil stove. Rather than evacuate the classroom and use the fire extinguisher, the teacher attempted to remove the stove itself from the classroom. During this process an explosion occurred resulting in a haphazard attempt at evacuation. This tragedy highlights gaps in both the policy and practice of fire safety. From 2005 to 2012, Iran experienced six large school fires that led to 67 injuries and five deaths. Five events were related to oil stoves. About 30% of Iran's classrooms use oil stoves for heating during the winter with 3.4 million students and 150,000 teachers at risk. Iran's Ministry of Education has mandated that regular training of school personnel in fire safety measures should be organized but no safety officer is tasked to prepare and conduct this training. Instead, the task is delegated to the Fire Departments, which fall under municipal administrations; however, such departments do not exist in 93% of the rural areas of Iran. School fires are not unique to Iran. Similar tragic events have occurred in several middle-income countries (India, Kenya, Russia) over the last decade. This article presents an overview of school fires in Iran and proposes preventive strategies through a reform in policy making and practice, including education of students and school personnel along with regular drills, designation of a fire safety officer, and development of a countrywide school fire registry.

Conflict, displacement and health in the Middle East

Displacement is a hallmark of modern humanitarian emergencies. Displacement itself is a traumatic event that can result in illness or death. Survivors face challenges including lack of adequate shelter, decreased access to health services, food insecurity, loss of livelihoods, social marginalisation as well as economic and sexual exploitation. Displacement takes many forms in the Middle East and the Arab World. Historical conflicts have resulted in long-term displacement of Palestinians. Internal conflicts have driven millions of Somalis and Sudanese from their homes. Iraqis have been displaced throughout the region by invasion and civil strife. In addition, large numbers of migrants transit Middle Eastern countries or live there illegally and suffer similar conditions as forcibly displaced people. Displacement in the Middle East is an urban phenomenon. Many displaced people live hidden among host country populations in poor urban neighbourhoods - often without legal status. This represents a challenge for groups attempting to access displaced populations. Furthermore, health information systems in host countries often do not collect data on displaced people, making it difficult to gather data needed to target interventions towards these vulnerable populations. The following is a discussion of the health impacts of conflict and displacement in the Middle East. A review was conducted of published literature on migration and displacement in the region. Different cases are discussed with an emphasis on the recent, large-scale and urban displacement of Iraqis to illustrate aspects of displacement in this region.

Facing the challenges in human resources for humanitarian health

The human resources crisis in humanitarian health care parallels that seen in the broader area of health care. This crisis is exacerbated by the lack of resources in areas in which humanitarian action is needed--difficult environments that often are remote and insecure--and the requirement of specific skill sets is not routinely gained during traditional medical training. While there is ample data to suggest that health outcomes improve when worker density is increased, this remains an area of critical under-investment in humanitarian health care. In addition to under-investment, other factors limit the availability of human resources for health (HRH) in humanitarian work including: (1) over-reliance on degrees as surrogates for specific competencies; (2) under-development and under-utilization of national staff and beneficiaries as humanitarian health workers; (3) lack of standardized training modules to ensure adequate preparation for work in complex emergencies; (4) and the draining of limited available HRH from countries with low prevalence and high need to wealthier, developed nations also facing HRH shortages. A working group of humanitarian health experts from implementing agencies, United Nations agencies, private and governmental financiers, and members of academia gathered at Hanover, New Hampshire for a conference to discuss elements of the HRH problem in humanitarian health care and how to solve them. Several key elements of successful solutions were highlighted, including: (1) the need to develop a set of standards of what would constitute "adequate training" for humanitarian health work; (2) increasing the utilization and professional development of national staff; (3) "training with a purpose" specific to humanitarian health work (not simply relying on professional degrees as surrogates); (4) and developing specific health task-based competencies thereby increasing the pool of potential workers. Such steps would accomplish several key goals, such as: (1) more confidently ensuring that individuals hired for a given post would have the capacity to function at a commonly understood level of training; (2) greatly increasing the potential number and types of workers available for humanitarian work; (3) increasing the efficiency of human resources utilization in humanitarian projects; and (4) recognition that humanitarian work is a multi-disciplinary endeavor: these goals will contribute to ensuring that humanitarian health workers have a minimum training in broader humanitarian action, making them more effective team members in the field. Efforts were made to highlight some promising pilot programs for human resource development in humanitarian work, to identify a future vision for humanitarian health as a profession, and to develop a human resources strategy for achieving that vision.

Intubation via LMA in pediatric patients with difficult airways

PURPOSE

To report two cases of successful tracheal intubation in difficult pediatric airways using a conventional laryngeal mask airway (LMA) with an extended polyvinyl chloride (PVC) tube after laryngeal assessment with a fibreoptic device.

CLINICAL FEATURES

Two cases, Dandy-Walker and Pierre Robin syndromes, were scheduled for surgery. They were premedicated with 0.5 mg x kg(-1) promethazine p.o. 90 min before surgery. Both patients arrived in the operating room sedated, with dry mouth, and without evidence of increased intracranial tension or airway obstruction. Inhalational induction with isoflurane 0.5-3% was commenced. Conventional tracheal intubation was impossible in both cases. In each an LMA was inserted to maintain ventilation, anesthesia, and to facilitate intubation. Fibreoptic bronchoscopy was used to assess the larynx, followed by blind intubation via the LMA using extended PVC tracheal tube (TT). Anesthesia was maintained during intubation using Mapleson F anesthesia circuit attached to a connector with fibreoptic bronchoscope adapter.

CONCLUSION

This report describes the assessment of the airway with fibreoptic bronchoscopy after LMA insertion facilitated blind tracheal intubation in two children with difficult airways.

Epidural ketamine reduces post-operative epidural PCA consumption of fentanyl/bupivacaine

PURPOSE

To study the analgesic effect of epidural ketamine on postoperative pain and epidural PCA consumption after total abdominal hysterectomy.

METHODS

Sixty-one ASA I-II patients, 34-60 yr were randomly assigned into three groups. Epidural catheters were inserted before induction of anaesthesia. Patients in group I and II received 30 mg ketamine epidurally before induction of anaesthesia or 20 min after skin incision: group III received placebo. Postoperatively, on first analgesia request, sedation score, Visual Analogue Scale (VAS), Prince Henry Score (PHS) and Bromage motor weakness score were taken and followed by an epidural bolus of 9 ml bupivacaine 0.25% + 50 micrograms fentanyl. Analgesia was maintained by PCA with a mixture of bupivacaine 0.1% + fentanyl 0.001% epidurally. Measurements were repeated at 1, 2, 4, 8, 12 and 24 hr.

RESULTS

First analgesia request was 17 +/- 6.8 min in the control group compared with 31.4 +/- 23.8 and 44 +/- 23.1 min for groups I and II respectively. The differences between group III and group I (P < 0.05) and between group III and group II (P < 0.01) were statistically significant. Twenty four hour PCA consumption was 101.2 +/- 47.2, 87 +/- 27 and 162 +/- 38 ml for groups I, II and III respectively. The differences between group III and group I and that between group III and group II were statistically significant (P < 0.001).

CONCLUSION

Epidural ketamine 30 mg reduces post hysterectomy pain as evidenced by prolongation of time to first analgesia request and reduction in postoperative epidural PCA consumption. This effect is manifest whether ketamine is given before induction or 20 min after skin incision.

Dose-response relationships for neostigmine antagonism of rocuronium-induced neuromuscular block in children and adults

Dose-response relationships for the antagonism of intermediate-acting neuromuscular blocking agents have not been evaluated previously in children. We have examined the dose-response relationships for neostigmine antagonism of 90% rocuronium-induced neuromuscular block in children and adults, during nitrous oxide-1 MAC of isoflurane anaesthesia. We studied 40 children, aged 2-10 yr, and 50 adults, aged 18-60 yr; all received a single bolus dose of rocuronium 0.6 mg kg-1 and accelerometry was used to monitor neuromuscular transmission. When the first twitch of the train-of-four (TOF) response (T1) recovered to 10% of its control (T0), one of five doses of neostigmine 0, 5, 10, 20 or 50 micrograms kg-1 was given by random allocation to each of the study groups (n = 8 children and n = 10 adults). Recovery of T1 and TOF ratio (T4/T1%) was recorded for 10 min after initial administration of neostigmine. Onset time of rocuronium-induced block was faster in children than in adults (mean 64.6 (95% confidence intervals 57.7-71.5) s vs 83.7 (70.7-96.6) s; P < 0.05). The time to 10% recovery of T1/T0 was shorter in children than in adults (25.4 (22.9-27.9) min vs 38.8 (36.1-41.4) min; P < 0.001). Spontaneous and antagonist-assisted recovery were more rapid in children than in adults. Adequate recovery (T4/T1 of 80%) occurred in children at 4, 5 and 8 min after neostigmine 50, 20 and 10 micrograms kg-1, respectively. Adequate recovery was not produced in adults by any dose of neostigmine within 10 min. The effective doses of neostigmine required to achieve a TOF ratio of 80% (ED80) after 10 min in children and adults were, respectively, 7.10 (5.2-9.8) micrograms kg-1 and 56.56 (45.5-71.9) micrograms kg-1 (P < 0.001). There was no advantage in administering doses of neostigmine greater than 20 micrograms kg-1 to antagonize 90% rocuronium-induced neuromuscular block in children. In contrast, it appeared prudent to use neostigmine 50 micrograms kg-1 or more for adequate antagonism of a similar degree of block in adults.
