Association between triage level and outcomes at Médecins Sans Frontières trauma hospital in Kunduz, Afghanistan, 2015.

BACKGROUND: Five million people die annually due to injuries; an increasing part is due to armed conflict in low-income and middle-income countries, demanding resolute emergency trauma care. In Afghanistan, a low-income country that has experienced conflict for over 35 years, conflict related trauma is a significant public health problem. To address this, the non-governmental organisation Médecins Sans Frontières (MSF) set up a trauma centre in Kunduz (Kunduz Trauma Centre (KTC)). MSF's standardised emergency operating procedures include the South African Triage Scale (SATS). To date, there are few studies that assess how triage levels correspond with outcome in low-resource conflict settings AIM: This study aims to assess to what extent SATS triage levels correlated to outcomes in terms of hospital admission, intensive care unit (ICU) admission and mortality for patients treated at KTC. METHOD AND MATERIALS: This retrospective study used routinely collected data from KTC registries. A total of 17 970 patients were included. The outcomes were hospital admission, ICU admission and mortality. The explanatory variable was triage level. Covariates including age, gender and delay to arrival were used. Logistic regression was used to study the correlation between triage level and outcomes. RESULTS: Out of all patients seeking care, 28.7% were triaged as red or orange. The overall mortality was 0.6%. In total, 90% of those that died and 79% of ICU-admitted patients were triaged as red. CONCLUSION: The risk of positive and negative outcomes correlated with triage level. None of the patients triaged as green died or were admitted to the ICU whereas 90% of patients who died were triaged as red.

Epidemiology of Patients Treated at the Emergency Department of a Médecins Sans Frontières Field Hospital During the Mosul Offensive: Iraq, 2017.

BACKGROUND: Armed conflicts constitute a significant public health problem, and the advent of asymmetric warfare tactics creates unique and new challenges to health care organizations providing trauma care in conflicts. OBJECTIVE: This study aimed to analyze the epidemiology of presentations to a civilian field hospital deployed close to an ongoing conflict. METHODS: During the 2016-2017 Mosul offensive, the humanitarian organization Médecins Sans Frontières deployed a field hospital 30 km south of Mosul. This study is a retrospective analysis of routinely collected patient data of all presentations to the emergency department (ED) during its period of operation between February 23 and July 18, 2017. Data were collected in Microsoft Excel by health care workers and analyzed in JMP, version 13. Chi-square test was used to compare proportions. A p value < 0.05 was considered significant. RESULTS: The analysis included 3946 presentations. Most were due to conflict-related injuries, including explosives (40.4%) and firearms (12.9%), which presented in consecutive waves over time. Approximately one-third of presentations (32.3%) were due to medical issues, which outweighed conflict-related presentations toward the latter half of the operational period. Explosives caused most of the mass casualty events. A total of 20 patients (0.5%) died in the ED. CONCLUSIONS: The study demonstrated a cyclical burden of conflict-related injuries and extensive medical needs, which increased over time. Among conflict-related injuries, explosive etiology predominated and was likely to result in mass casualty incidents. The low mortality might be due to critical but potentially salvageable patients not reaching the hospital in time, owing to the adverse context.

Preventing avoidable hospital admissions after emergency care in humanitarian settings: a cross-sectional review of Médecins Sans Frontières emergency departments.

OBJECTIVES: The aim of this study was to describe the types of emergency departments (EDs), and the acuity, types and disposition of conditions managed at Médecins Sans Frontières (MSF)-supported EDs in humanitarian settings. DESIGN, SETTING, PARTICIPANTS AND OUTCOME MEASURES: This was a multicentre, cross-sectional review of visits to MSF-supported EDs from 1 January 2014 to 31 December 2018. EDs were classified into advanced-level, general-level, paediatric and trauma. Variables analysed included: age group, condition, acuity and ED disposition. Frequencies and percentages stratified by ED type or region were reported. RESULTS: MSF supported 26 EDs in 12 countries, with a total of 1 388 698 visits between 2014 and 2018. Most patients were discharged home (n=1 097 456, 79%), with nearly 0% mortality (n=4692). The majority of visits at general-level and paediatric EDs were for medical conditions (n=600 088, 78% and n=45 276, 96%, respectively), while nearly half of advanced-level EDs visits were for surgical conditions (n=201 189, 48%). Almost all visits to trauma EDs were for surgical conditions (n=148 078, 98%). Overall, most surgical conditions were traumatic injuries (n=484 008, 94%), the majority unintentional (n=425 487, 82%). The top three most common classified medical conditions were respiratory infections, malaria and diarrhoea. CONCLUSIONS: EDs are critical in improving the agility and access to emergency care (EC) in humanitarian settings. This study demonstrated that EC provision resulted in the majority of patients being discharged from EDs, helping prevent avoidable hospital admissions. These results could help better understand the healthcare needs of vulnerable populations, improve responsiveness to emergency conditions and support programmatic planning in humanitarian settings.

The Effect of Conflict on Obstetric and Non-Obstetric Surgical Needs and Operative Mortality in Fragile States.

BACKGROUND: Médecins Sans Frontières (MSF) provides surgical care in fragile states, which are more vulnerable to conflict. The primary objective of this study was to compare the indications for operative intervention in surgical projects in fragile states during periods of active conflict (CON) and non-conflict (NON-CON). In addition, risk factors for non-obstetric and obstetric operative mortality were identified. METHODS: This was a retrospective analysis of MSF surgical projects in fragile states January 1, 2008-December 31, 2017. Variables considered in the analysis include age, gender, American Society of Anesthesiology physical status, emergency status, re-intervention status, indication for surgical intervention, and conflict/non-conflict time period. RESULTS: There were 30 surgical projects in 13 fragile states with 87,968 surgical interventions in 68,667 patients. Obstetric needs were the most common indication for surgical intervention (n = 28,060, 31.9%) but were more common during NON-CON (n = 23,142, 35.7%) compared to CON periods (n = 4,918, 21.2%, p < 0.001). Trauma was more common during CON (42.0%) compared to NON-CON (23.0%) periods (p < 0.001). Non-obstetric operative mortality was similar during CON (0.2%) compared to NON-CON (0.2%, p = 0.920), but obstetric operative mortality was higher (0.5%) during CON compared to NON-CON (0.2%, p < 0.001) periods. Risk factors for obstetric and non-obstetric mortality included age ≥ 30 years, ASA greater than 1, and emergency intervention. CONCLUSION: Humanitarian surgeons working in fragile states should be prepared to treat a range of surgical needs including trauma and obstetrics during conflict and non-conflict periods. The mortality in obstetric patients was higher during conflict periods, and further research to understand ways to protect this vulnerable group is needed.

Traumatic Injuries are the Main Indication for Limb Amputations During and After Humanitarian Crises.

BACKGROUND: Populations at risk during humanitarian crises can suffer traumatic injuries or have medical conditions that result in the need for limb amputation (LA). The objectives of this study were to describe the indications for and associations with LA during and after humanitarian crises in surgical projects supported by Médecins Sans Frontières (MSF). METHODS: MSF-Operational Center Brussels data from January 1, 2008, to December 31, 2017, were analyzed. Surgical projects were classified into (annual) periods of crises and post-crises. Indications were classified into trauma (intentional and unintentional) and non-trauma (medical). Associations with LA were also reported. RESULTS: MSF-OCB performed 936 amputations in 17 countries over the 10-year study period. 706 (75%) patients were male and the median age was 27 years (interquartile range 17-41 years). Six hundred and twenty-one (66%) LA were performed during crisis periods, 501 (53%) during conflict and 119 (13%) post-natural disaster. There were 316 (34%) LA in post-crisis periods. Overall, trauma was the predominant indication (n = 756, 81%) and accounted for significantly more LA (n = 577, 94%) in crisis compared to post-crisis periods (n = 179, 57%) (p < 0.001). DISCUSSION: Our study suggests that populations at risk for humanitarian crises are still vulnerable to traumatic LA. Appropriate operative and post-operative LA management in the humanitarian setting must be provided, including rehabilitation and options for prosthetic devices.

Evaluation of multiple open-source deep learning models for detecting and grading COVID-19 on chest radiographs.

Purpose: Chest x-rays are complex to report accurately. Viral pneumonia is often subtle in its radiological appearance. In the context of the COVID-19 pandemic, rapid triage of cases and exclusion of other pathologies with artificial intelligence (AI) can assist over-stretched radiology departments. We aim to validate three open-source AI models on an external test set. Approach: We tested three open-source deep learning models, COVID-Net, COVIDNet-S-GEO, and CheXNet for their ability to detect COVID-19 pneumonia and to determine its severity using 129 chest x-rays from two different vendors Phillips and Agfa. Results: All three models detected COVID-19 pneumonia (AUCs from 0.666 to 0.778). Only the COVID Net-S-GEO and CheXNet models performed well on severity scoring (Pearson's r 0.927 and 0.833, respectively); COVID-Net only performed well at either task on images taken with a Philips machine (AUC 0.735) and not an Agfa machine (AUC 0.598). Conclusions: Chest x-ray triage using existing machine learning models for COVID-19 pneumonia can be successfully implemented using open-source AI models. Evaluation of the model using local x-ray machines and protocols is highly recommended before implementation to avoid vendor or protocol dependent bias.

Hippopotamus bite morbidity: a report of 11 cases from Burundi.

Hippopotamus is one of the most-loved animals in Africa, yet it is aggressive and dangerous. The co-existence of humans in close proximity to their natural habitat increases the probability of human injury. Hippopotamus attacks have long been recognized to cause serious injuries, but its magnitude and burden are still unknown. The medical literature is very scarce when it comes to documenting hippopotamus bite injuries and their outcomes. We present a cohort of 11 patients who suffered hippopotamus bite injuries in Burundi. To our knowledge, this is the largest case series reporting on the clinical presentation, injury patterns and surgical outcomes of hippopotamus bites. The results show a high incidence of wound infections, amputations and permanent disability among other complications. Hippopotamus-inflicted injuries should, therefore, be triaged as major trauma rather than just 'mammalian bites'.

Anaesthesia care providers employed in humanitarian settings by Médecins Sans Frontières: a retrospective observational study of 173 084 surgical cases over 10 years.

OBJECTIVE: To describe the extent to which different categories of anaesthesia provider are used in humanitarian surgical projects and to explore the volume and nature of their surgical workload. DESIGN: Descriptive analysis using 10 years (2008-2017) of routine case-level data linked with routine programme-level data from surgical projects run exclusively by Médecins Sans Frontières-Operational Centre Brussels (MSF-OCB). SETTING: Projects were in contexts of natural disaster (ND, entire expatriate team deployed by MSF-OCB), active conflict (AC) and stable healthcare gaps (HG). In AC and HG settings, MSF-OCB support pre-existing local facilities. Hospital facilities ranged from basic health centres with surgical capabilities to tertiary referral centres. PARTICIPANTS: The full dataset included 178 814 surgical cases. These were categorised by most senior anaesthetic provider for the project, according to qualification: specialist physician anaesthesiologists, qualified nurse anaesthetists and uncertified anaesthesia providers. PRIMARY OUTCOME MEASURE: Volume and nature of surgical workload of different anaesthesia providers. RESULTS: Full routine data were available for 173 084 cases (96.8%): 2518 in ND, 42 225 in AC, 126 936 in HG. Anaesthesia was predominantly led by physician anaesthesiologists (100% in ND, 66% in AC and HG), then nurse anaesthetists (19% in AC and HG) or uncertified anaesthesia providers (15% in AC and HG). Across all settings and provider groups, patients were mostly healthy young adults (median age range 24-27 years), with predominantly females in HG contexts, and males in AC contexts. Overall intra-operative mortality was 0.2%. CONCLUSION: Our findings contribute to existing knowledge of the nature of anaesthetic provision in humanitarian settings, while demonstrating the value of high-quality, routine data collection at scale in this sector. Further evaluation of perioperative outcomes associated with different models of humanitarian anaesthetic provision is required.

North American pediatric surgery fellows' preparedness for humanitarian surgery.

INTRODUCTION: The overwhelming burden of pediatric surgical need in humanitarian settings has prompted mutual interest between humanitarian organizations and pediatric surgeons. To assess adequate fit, we correlated pediatric surgery fellowship case mix and load with acute pediatric surgical relief efforts in conflict and disaster zones. METHODS: We reviewed pediatric (age < 18) cases logged by the Médecins Sans Frontières Operational Centre Brussels (MSF-OCB) from a previously validated and published database spanning 2008-2014 and cases performed by American College of Graduate Medical Education (ACGME) pediatric surgery graduates from 2008 to 2018. Non-operative management for trauma, endoscopic procedures, and basic wound care were excluded as they were not tracked in either dataset. ACGME procedures were classified under 1 of 32 MSF pediatric surgery procedure categories and compared using chi-squared tests. RESULTS: ACGME fellows performed procedures in 44% of tracked MSF-OCB categories. Major MSF-OCB pediatric cases were comprised of 62% general surgery, 23% orthopedic surgery, 9% obstetrical surgery, 3% plastic/reconstructive surgery, 2% urogynecologic surgery, and 1% specialty surgery. In comparison, fellows' cases were 95% general surgery, 0% orthopedic surgery, 0% obstetrical surgery, 5% urogynecologic surgery, and 1% specialty surgery. Fellows more frequently performed abdominal, thoracic, other general surgical, urology/gynecologic, and specialty procedures, but performed fewer wound and burn procedures (all p < 0.05). Fellows received no experience in Cesarean section or open fracture repair. Fellows performed a greater proportion of surgeries for congenital conditions (p < 0.05). CONCLUSION: While ACGME pediatric surgical trainees receive significant training in general and urogynecologic surgical techniques, they lack sufficient case load for orthopedic and obstetrical care - a common need among children in humanitarian settings. Trainees and program directors should evaluate the fellow's role and scope in a global surgery rotation or provide advanced preparation to fill these gaps. Upon graduation, pediatric surgeons interested in humanitarian missions should seek out additional orthopedic and obstetrical training, or select missions that do not require such skillsets. LEVEL OF EVIDENCE: III.

Comparison of Operative Logbook Experience of Australian General Surgical Trainees With Surgeons Deployed on Humanitarian Missions: What Can Be Learnt for the Future?

OBJECTIVE: General surgical training in Australia has undergone considerable change in recent years with less exposure to other areas of surgery. General surgeons from many high-income countries have played important roles in assisting with the provision of surgical care in low- and middle-income countries during sudden-onset disasters (SODs) as part of emergency medical teams (EMTs). It is not known if contemporary Australian general surgeons are receiving the broad surgical training required for work in EMTs. DESIGN: Logbook data on the surgical procedures performed by Australian general surgical trainees were obtained from General Surgeons Australia (GSA) for the time period February 2008 to February 2017. Surgical procedures performed by Médecins sans Frontières (MSF) surgeons during 5 projects in 3 SODs (the 2010 Haiti earthquake, the 2013 Philippines typhoon and the 2015 Nepal earthquake) were obtained from previously published data for 6 months following each disaster. SETTING AND PARTICIPANTS: This was carried out at the University of Sydney with input from MSF Operational Centre Brussels and GSA. RESULTS: Australian general surgical trainees performed a mean of 2107 surgical procedures (excluding endoscopy) during their training (10 6-month rotations). Common procedures included abdominal wall hernia repairs (268, 12.7%), cholecystectomies (247, 11.8%), and specialist colorectal procedures (242, 11.5%). MSF surgeons performed a total of 3542 surgical procedures across the 5 projects analyzed. Common procedures included Caesarean sections (443, 12.5%), wound debridement (1115, 31.5%), and other trauma-related procedures (472, 13.3%). CONCLUSIONS: Australian general surgical trainees receive exposure to both essential and advanced general surgery but lack exposure to specialty procedures including the obstetric and orthopedic procedures commonly performed by MSF surgeons after SODs. Further training in these areas would likely be beneficial for general surgeons prior to deployment with an EMT.
