Although there are now approved treatments and vaccines for Ebola virus disease (EVD), the case fatality of EVD remains unacceptably high even when treated with the newly approved therapeutics; furthermore, these countermeasures are not expected to be effective against disease caused by other filoviruses. A meeting of subject matter experts from public health, research, and countermeasure development agencies and manufacturers was held during the 10th International Filovirus Symposium to discuss strategies to address these gaps, including how newer countermeasures could be advanced for field readiness. Several investigational therapeutics, vaccine candidates, and combination strategies were presented. In all, a common theme emerged: the greatest challenge to completing development was the implementation of well-designed clinical trials of safety and efficacy during filovirus disease outbreaks. These outbreaks are usually of short duration, providing but a brief opportunity for trials to be launched, and have too few cases to allow for full enrollment during a single outbreak, so clinical trials will necessarily need to span multiple outbreaks which may occur in a number of at-risk countries. Preparing for this will require agreed-upon common protocols for trials intended to bridge multiple outbreaks across all at-risk countries. A multi-national research consortium including, and led by, at-risk countries would be an ideal mechanism to negotiate agreement on protocol design and coordinate preparation. Discussion participants recommended a follow-up meeting be held in Africa with national public health and research agencies from at-risk countries to establish such a consortium.

INTRODUCTION
During January 2010, a 7.0 magnitude earthquake struck Haiti, resulting in death and destruction for hundreds of thousands of people. This study describes the types of orthopedic procedures performed, the options for patient follow-up, and limitations in obtaining outcomes data in an emergency setting.
PROBLEM
There is not a large body of data that describes larger orthopedic cohorts, especially those focusing on internal fixation surgeries in resource-poor settings in postdisaster regions. This article describes 248 injuries and over 300 procedures carried out in the Médecins Sans Frontières-Orthopedic Centre Paris orthopedic program.
METHODS
Surgeries described in this report were limited to orthopedic procedures carried out under general anesthesia for all surgical patients. Exclusion factors included simple fracture reduction, debridement, dressing changes, and removal of hardware. This data was collected using both prospective and retrospective methods; prospective inpatient data were collected using a data collection form designed promptly after the earthquake and retrospective data collection was performed in October 2010.
RESULTS
Of the 264 fractures, 204 were fractures of the major long bones (humerus, radius, femur, tibia). Of these 204 fractures of the major long bones, 34 (16.7%) were upper limb fractures and 170 (83.3%) were lower limb fractures. This cohort demonstrated a large number of open fractures of the lower limb and closed fractures of the upper limb. Fractures were treated according to their location and type. Of the 194 long bone fractures, the most common intervention was external fixation (36.5%) followed by traction (16.7%), nailing (15.1%), amputation (14.6%), and plating (9.9%).
CONCLUSION
The number of fractures described in this report represents one of the larger orthopedic cohorts of patients treated in a single center in the aftermath of the 2010 earthquake in Haiti. The emergent surgical care described was carried out in difficult conditions, both in the hospital and the greater community. While outcome and complication data were limited, the proportion of patients attending follow-up most likely exceeded expectations and may reflect the importance of the rehabilitation center. This data demonstrates the ability of surgical teams to perform highly-specialized surgeries in a disaster zone, and also reiterates the need for access to essential and emergency surgical programs, which are an essential part of public health in low- and medium-resource settings.

Role of Anesthesiology in Global Health. 19 November 2014; DOI:10.1007/978-3-319-09423-6_9
Médecins Sans Frontières/Doctors Without Borders (MSF) has been running surgical programs since the early 1980s. This chapter provides an overview of the anesthesia component of these programs and explores some lessons learned from the experience of one of MSF’s five Operations Centers—in this case, the Belgium-based unit (MSF-Belgium). During the period from 2010 until the end of 2013, these projects provided surgical care to more than 56,000 surgical patients in 23 countries and performed over 73,000 surgical procedures. This experience has shown that surgeons and anesthetists need to discard preconceived notions of an inevitable link between the technical complexity of surgical and anesthesia techniques and the ability to reduce morbidity and mortality. On the contrary, MSF has found that keeping our interventions simple, accessible and sustainable within a given context is often the most effective way to best serve the needs of the many.

BACKGROUND
Lower extremity trauma during earthquakes accounts for the largest burden of geophysical disaster-related injuries. Insufficient pain management is common in disaster settings, and regional anesthesia (RA) has the potential to reduce pain in injured patients beyond current standards. To date, no prospective research has evaluated the use of RA in a disaster setting. This cross-sectional study assesses knowledge translation and skill acquisition outcomes for lower extremity RA performed with and without ultrasound guidance among a cohort of Médecins Sans Frontières (MSF) volunteers who will function as proceduralists in a planned randomized controlled trial evaluating the efficacy of RA for pain management in an earthquake setting.
METHODS
Generalist humanitarian healthcare responders, including both physicians and nurses, were trained in ultrasound guided femoral nerve block (USGFNB) and landmark guided fascia iliaca compartment block (LGFICB) techniques using didactic sessions and interactive simulations during a one-day focused course. Outcome measures evaluated interval knowledge attainment and technical proficiency in performing the RA procedures. Knowledge attainment was assessed via pre- and post-test evaluations and procedural proficiency was evaluated through monitored simulations, with performance of critical actions graded by two independent observers.
RESULTS
Twelve humanitarian response providers were enrolled and completed the trainings and assessments. Knowledge scores significantly increased from a mean pre-test score of 79% to post-test score of 88% (p<0.001). In practical evaluation of the LGFICB, participants correctly performed a median of 15.0 (Interquartile Range (IQR) 14.0-16.0) out of 16 critical actions. For the USGFNB, the median score was also 15.0 (IQR 14.0-16.0) out of 16 critical actions. Inter-rater reliability for completion of critical actions was excellent, with inter-rater agreement of 83.3% and 91.7% for the LGFICB and USGFNB evaluations, respectively.
DISCUSSION
Prior to conducting a trial of RA in a disaster setting, providers need to gain understanding and skills necessary to perform the interventions. This evaluation demonstrated attainment of high knowledge and technical skill scores in both physicians and nurses after a brief training in regional anesthesia techniques. This study demonstrates the feasibility of rapidly training generalist humanitarian responders to provide both LGFICB and USGFNB during humanitarian emergencies.

BACKGROUND
Compared to high-income settings, survival in burn units in low-income settings is lower with invasive infections one leading cause of death. Médecins Sans Frontières is involved in the treatment of large burns in adults and children in Haiti.
METHODS
In 2014, we performed a review of 228 patients admitted consecutively with burn injury during a 6-month period to determine patient outcomes and infectious complications. Microbiology was available through a linkage with a Haitian organization. Regression analysis was performed to determine covariates associated with bloodstream infection and mortality.
RESULTS
102 (45 %) patients were male, the median age was 8 years (IQR, 2-28), and the majority of patients (60 %) were admitted to the unit within 6 h of injury. There were 20 patients (9 %) with culture-proven bacteremia. Among organisms in blood, common isolates were Staphylococcus aureus (42 %), Pseudomonas aeruginosa (23 %), and Acinetobacter baumannii (15 %). Among patients with burns involving <40 % total body area, 4 (2 %) of 192 died and 20 (65 %) of 31 with ≥40 % body surface area involvement died. Factors associated with mortality included involvement of ≥40 % of body surface, depth, and flame as the mechanism. Multidrug-resistant infections were common; 18 % of S. aureus isolates were methicillin resistant, and 83 % of P. aeruginosa isolates were imipenem resistant.
CONCLUSIONS
A low mortality rate was observed in a humanitarian burn surgery project in patients with burns involving <40 % of total body surface. Invasive infection was common and alarming rates of antibiotic resistance were observed, including infections not treatable with antibiotics available locally.

IMPORTANCE
Little is known about the scope of practice and outcomes in pediatric surgery performed by humanitarian organizations in resource-poor settings and conflict zones. This study provides the largest report to date detailing such data for a major nongovernmental organization providing humanitarian surgical relief support in these settings.
OBJECTIVE
To characterize pediatric surgical care provision by a major nongovernmental organization in specialized humanitarian settings and conflict zones.
DESIGN, SETTING AND PARTICIPANTS
A retrospective cohort study was conducted from August 15, 2014, to March 9, 2015, of 59 928 surgical interventions carried out from January 1, 2012, to December 31, 2013, by the Médecins Sans Frontières Operational Centre Paris (MSF-OCP) program in 20 locations, including South Sudan, Yemen, Syria, Gaza, Pakistan, Nigeria, Central African Republic, Democratic Republic of Congo, and the Philippines. Surgical interventions were primarily for general surgical, traumatic, and obstetric emergencies and were categorized by mechanism, type of intervention, American Society of Anesthesia risk classification, and urgency of intervention.
MAIN OUTCOMES AND MEASURES
Operative indications, type of intervention, and operative case mortality.
RESULTS
Among all age groups, 59 928 surgical interventions were performed in dedicated trauma, obstetric, and reconstructive centers for 2 years. Nearly one-third of interventions (18 040 [30.1%]) involved preteen patients (aged <13 years) and 4571 (7.6%) involved teenaged patients (aged 13-17 years). The proportion of violence-related injuries in the preteen group was significantly lower than in the teenage group (4.8% vs 17.5%; P < .001). Burns (50.1%), other accidental injuries (16.4%), and infections (23.4%) composed the bulk of indications in the preteen group. Interventions in the teenage group were principally caused by trauma-related injuries (burns, 22.9%; traffic accidents, 10.1%; gunshot wounds, 8.0%). Crude perioperative case mortality rates were 0.07% in the preteen group, 0.15% in the teenage group, and 0.22% in the adult group (>17 years) (P = .001). One-third of the cases (33.4%) were deemed urgent, while most of the remaining cases (57.7%) were deemed semielective (surgical intervention to be performed within 48 hours).
CONCLUSIONS AND RELEVANCE
When examining surgical interventions in a population of pediatric patients cared for in the specialized setting of humanitarian aid and conflict zones, burns, other accidental injuries, and infection composed the bulk of indications in the preteen group; interventions in the teenage group were principally caused by trauma-related injuries. Crude perioperative case mortality rates in the preteen group were significantly lower than in the adult group. Further work is needed to examine long-term outcomes of pediatric operations in these settings and to guide context-specific surgical program development.

BACKGROUND/OBJECTIVES
The MSF programme in Jordan provides specialized reconstructive surgical care to war-wounded civilians in the region. The short musculoskeletal functional assessment score (SMFA) provides a method for quantitatively assessing functional status following orthopaedic trauma. In June 2010 the Amman team established SMFA as the standard for measuring patients’ functional status. The objective of this retrospective study is to evaluate whether the SMFA scores can be useful for patients with chronic war injuries.
METHODS
All patients with lower limb injuries requiring reconstruction were enrolled in the study. Each patient's SMFA was assessed at admission, at discharge from Amman and during follow-up in home country. In the analysis we compared patients with infected versus non-infected injuries as well as with both high and low admissions dysfunctional index (ADI).
RESULTS
Among infected patients, higher ADI correlated with more surgeries and longer hospital stay. Infected patients with ADI >50 required an average of 2.7 surgeries while those with ADI <50, averaged 1.7 operations (p = 0.0809). Non-infected patients with ADI >50 required an average of 1.6 operations compared to 1.5 for those with ADI <50 (p = 0.4168).
CONCLUSIONS
The ADI score in our sample appeared to be useful in two areas: (1) hospital course in patients with infection, where a high ADI score correlated with longer hospital stays and more surgeries, and (2) prognosis, which was better for non-infected patients who had high ADI scores. A scoring system that predicts functional outcome following surgical reconstruction of lower limb injuries would be enormously useful.

The epidemiology of surgical site infections (SSIs) in surgical programmes in sub-Saharan Africa is inadequately described. We reviewed deep and organ-space SSIs occurring within a trauma project that had a high-quality microbiology partnership and active follow-up. Included patients underwent orthopaedic surgery in Teme Hospital (Port Harcourt, Nigeria) for trauma and subsequently developed a SSI requiring debridement and microbiological sampling. Data were collected from structured chart reviews and programmatic databases for 103 patients with suspected SSI [79% male, median age 30 years, interquartile range (IQR) 24-37]. SSIs were commonly detected post-discharge with 58% presenting >28 days after surgery. The most common pathogens were: Staphylococcus aureus (34%), Pseudomonas aeruginosa (16%) and Enterobacter cloacae (11%). Thirty-three (32%) of infections were caused by a multidrug-resistant (MDR) pathogen, including 15 patients with methicillin-resistant S. aureus. Antibiotics were initiated empirically for 43% of patients and after culture and sensitivity report in 32%. The median number of additional surgeries performed in patients with SSI was 5 (IQR 2-6), one patient died (1%), and amputation was performed or recommended in three patients. Our findings suggest the need for active long-term monitoring of SSIs, particularly those associated with MDR organisms, resulting in increased costs for readmission surgery and treatment with late-generation antibiotics.

BACKGROUND
Lower extremity trauma during earthquakes accounts for the largest burden of disaster-related injuries. Insufficient pain management is common in resource-limited disaster settings, and regional anesthesia (RA) may reduce pain in injured patients beyond current standards of care. To date, no controlled trials have been conducted to evaluate the use of RA for pain management in a disaster setting.
METHODS/DESIGN
The Regional Anesthesia for Painful Injuries after Disasters (RAPID) study aims to evaluate whether regional anesthesia (RA), either with or without ultrasound (US) guidance, can reduce pain from earthquake-related lower limb injuries in a disaster setting. The proposed study is a blinded, randomized controlled equivalence trial among earthquake victims with serious lower extremity injuries in a resource-limited setting. After obtaining informed consent, study participants will be randomized in a 1:1:1 allocation to either: standard care (parenteral morphine at 0.1 mg/kg); standard care plus a landmark-guided fascia iliaca compartment block (FICB); or standard care plus an US-guided femoral nerve block. General practice humanitarian response providers who have undergone a focused training in RA will perform nerve blocks with 20 ml 0.5 % levobupivacaine. US sham activities will be used in the standard care and FICB arms and a normal saline injection will be given to the control group to blind both participants and nonresearch team providers. The primary outcome measure will be the summed pain intensity difference calculated using a standard 11-point Numerical Rating Scale reported by patients over 24 h of follow-up. Secondary outcome measures will include overall analgesic requirements, adverse events, and participant satisfaction.
DISCUSSION
Given the high burden of lower extremity injuries in the aftermath of earthquakes and the currently limited treatment options, research into adjuvant interventions for pain management of these injuries is necessary. While anecdotal reports on the use of RA for patients injured during earthquakes exist, no controlled studies have been undertaken. If demonstrated to be effective in a disaster setting, RA has the potential to significantly assist in reducing both acute suffering and long-term complications for survivors of earthquake trauma.

While anecdotal reports on the use of RA for patients injured during earthquakes exist, no controlled studies have been undertaken. If demonstrated to be effective in a disaster setting, RA has the potential to significantly assist in reducing both acute suffering and long-term complications for survivors of earthquake trauma.

Lower respiratory tract infections (LRTIs) are the leading cause of deaths in children < 5 years old worldwide, particularly affecting low-resource settings such as Aweil, South Sudan. In these settings, diagnosis can be difficult because of either lack of access to radiography or clinical algorithms that overtreat children with antibiotics who only have viral LRTIs. Point-of-care ultrasound (POCUS) has been applied to LRTIs, but not by nonphysician clinicians, and with limited data from low-resource settings. Our goal was to examine the feasibility of training the mid-level provider cadre clinical officers (COs) in a Médecins Sans Frontières project in South Sudan to perform a POCUS algorithm to differentiate among causes of LRTI. Six COs underwent POCUS training, and each subsequently performed 60 lung POCUS studies on hospitalized pediatric patients < 5 years old with criteria for pneumonia. Two blinded experts, with a tiebreaker expert adjudicating discordant results, served as a reference standard to calculate test performance characteristics, assessed image quality and CO interpretation. The COs performed 360 studies. Reviewers rated 99.1% of the images acceptable and 86.0% CO interpretations appropriate. The inter-rater agreement (κ) between COs and experts for lung consolidation with air bronchograms was 0.73 (0.63-0.82) and for viral LRTI/bronchiolitis was 0.81 (0.74-0.87). It is feasible to train COs in South Sudan to use a POCUS algorithm to diagnose pneumonia and other pulmonary diseases in children < 5 years old.
