Challenges Locating the Scene of Emergency: A Qualitative Study of the EMS System in Rwanda.

BACKGROUND: Timely prehospital emergency care significantly improves health outcomes. One substantial challenge delaying prehospital emergency care is in locating the patient requiring emergency services. The goal of this study was to describe challenges emergency medical services (EMS) teams in Rwanda face locating emergencies, and explore potential opportunities for improvement. METHODS: Between August 2021 and April 2022, we conducted 13 in-depth interviews with three stakeholder groups representing the EMS response system in Rwanda: ambulance dispatchers, ambulance field staff, and policymakers. Semi-structured interview guides covered three domains: 1) the process of locating an emergency, including challenges faced; 2) how challenges affect prehospital care; and 3) what opportunities exist for improvement. Interviews lasted approximately 60 min, and were audio recorded and transcribed. Applied thematic analysis was used to identify themes across the three domains. NVivo (version 12) was used to code and organize data. RESULTS: The current process of locating a patient experiencing a medical emergency in Kigali is hampered by a lack of adequate technology, a reliance on local knowledge of both the caller and response team to locate the emergency, and the necessity of multiple calls to share location details between parties (caller, dispatch, ambulance). Three themes emerged related to how challenges affect prehospital care: increased response interval, variability in response interval based on both the caller's and dispatcher's individual knowledge of the area, and inefficient communication between the caller, dispatch, and ambulance. Three themes emerged related to opportunities for processes and tools to improve the location of emergencies: technology to geolocate an emergency accurately and improve the response interval, improvements in communication to allow for real-time information sharing, and better location data from the public. CONCLUSION: This study has identified challenges faced by the EMS system in Rwanda in locating emergencies and identified opportunities for intervention. Timely EMS response is essential for optimal clinical outcomes. As EMS systems develop and expand in low-resource settings, there is an urgent need to implement locally relevant solutions to improve the timely locating of emergencies.

Challenges and opportunities to improve efficiency and quality of prehospital emergency care using an mHealth platform: Qualitative study in Rwanda.

Introduction: Prompt, high-quality pre-hospital emergency medical services (EMS) can significantly reduce morbidity and mortality. The goal of this study was to identify factors that compromise efficiency and quality of pre-hospital emergency care in Rwanda, and explore the opportunities for a mobile health (mHealth) tool to address these challenges. Methods: In-depth interviews were conducted with 21 individuals representing four stakeholder groups: EMS dispatch staff, ambulance staff, hospital staff, and policymakers. A semi-structured interview guide explored participants' perspectives on all aspects of the pre-hospital emergency care continuum, from receiving a call at dispatch to hospital handover. Participants were asked how the current system could be improved, and the potential utility of an mHealth tool to address existing challenges. Interviews were audio-recorded, and transcripts were thematically analyzed using NVivo. Results: Stakeholders identified factors that compromise the efficiency and quality of care across the prehospital emergency care continuum: triage at dispatch, dispatching the ambulance, locating the emergency, coordinating patient care at scene, preparing the receiving hospital, and patient handover to the hospital. They identified four areas where an mHealth tool could improve care: efficient location of the emergency, streamline communication for decision making, documentation with real-time communication, and routine data for quality improvement. While stakeholders identified advantages of an mHealth tool, they also mentioned challenges that would need to be addressed, namely: limited internet bandwidth, capacity to maintain and update software, and risks of data security breaches that could lead to stolen or lost data. Conclusion: Despite the success of Rwanda's EMS system, this study highlights factors across the care continuum that could compromise quality and efficiency of prehospital emergency care. Mobile health tools hold great promise to address these challenges, but contextual issues need to be considered to ensure sustainability of use.

Surgical Capacity Building in Low- and Middle-Income Countries: Lessons for Thoracic Surgery.

There is great need for intentional investment in capacity building for thoracic surgical conditions. This article provides a brief overview of thoracic surgical capacity building for low- and middle-income countries using the Lancet framework of infrastructure, workforce, financing, and information management. The authors highlight the needs, opportunities, and challenges that are relevant for the thoracic surgical community, as it aims to increase care for patients with these conditions globally.

Developing Sustainable Prehospital Pediatric Care in Rwanda.

OBJECTIVE: Unintentional injury is the leading cause of death in children older than 1 year and disproportionately affects pediatric patients in low- and middle-income countries.Improved prehospital care capacity has demonstrated the ability to improve care and save lives. Our collaboration developed and implemented a sustainable prehospital emergency pediatrics care course (EPCC) for Service d'Aide Medicale Urgente, the public emergency medical service in Rwanda. METHODS: A 1-day context-specific EPCC was developed based on international best practices and local feedback. Two cohorts were created to participate in the course. The first group, EPCC 1, was made of 22 Service d'Aide Medicale Urgente providers with preexisting knowledge on the topic who participated in the course and received training to lead future sessions. After completion of the EPCC1, this group led the second cohort, EPCC 2, which was composed of 26 healthcare providers from around Rwanda. Each group completed a 50 question assessment before and after the course. RESULTS: Emergency pediatrics care course 1 mean scores were 58% vs 98% (pre vs post), EPCC 2 mean scores were 49% vs 98% (pre vs post), using matched-pair analysis of 22 and 32 participants, respectively. When comparing unequal variances across the groups with a 2-tailed paired t test, EPCC 1 and EPCC 2 had a statistically significant mean change in pretest and posttest assessment test scores of 40% compared with 46%, P < 0.0001, with 95% confidence interval. A 1-way analysis of variance mean square analysis for the change in scores showed that regardless of the baseline level of training for each participant, all trainees reached similar postassessment scores (F(1) = 1.45, P = 0.2357). CONCLUSIONS: This study demonstrates effective implementation of a context-appropriate prehospital pediatric training program in Kigali, Rwanda. This program may be effective to support capacity development for prehospital care in Rwanda using a qualified local source of instructors.

Cost-Effectiveness of Lay First Responders Addressing Road Traffic Injury in Sub-Saharan Africa.

BACKGROUND: To investigate the cost-effectiveness of training lay first responders (LFRs) to address road traffic injury (RTI) in sub-Saharan Africa (SSA) as the first step toward formal emergency medical services (EMS) development. MATERIALS/METHODS: Cost data from five LFR programs launched between 2008 and 2019 in SSA was collected for LFR cost estimation, including three prospective collections from our group. We systematically reviewed literature and projected aggregate disability-adjusted life years (DALYs) from RTI in SSA that are addressable by LFRs to inform cost-effectiveness ratios ($USD cost per DALY averted). Cost-effectiveness ratios were then compared against African per capita gross domestic product (GDP) to determine the cost-effectiveness of LFRs addressing RTIs in SSA, following WHO-CHOICE guidelines, which state cost-effectiveness ratios less than GDP per capita are considered "very cost-effective." RESULTS: Average annual cost per LFR trained across five programs was calculated to be 16.32USD (training=4.04USD, supplies=12.28USD). Following WHO and Disease Control Priorities recommendations for adequate emergency catchment, initial training of 750 LFRs per 100,000 people would cost 12,239.47USD with projected total annual DALYs averted equal to 227.7 per 100,000. Cost per DALY averted would therefore be 53.75USD with appropriate LFR availability, less than sub-Saharan African GDP per capita (1,585.40USD) and the lowest sub-Saharan African GDP per capita (Burundi, 261.20USD). CONCLUSION: Following WHO-CHOICE guidelines, training LFRs can be a highly cost-effective means to address RTI morbidity and mortality across sub-Saharan Africa. With EMS unavailable for 91.3% of the African population, training LFRs can be an affordable first step toward formal EMS development.

Academic Global Surgery Curricula: Current Status and a Call for a More Equitable Approach.

INTRODUCTION: We aimed to search the literature for global surgical curricula, assess if published resources align with existing competency frameworks in global health and surgical education, and determine if there is consensus around a fundamental set of competencies for the developing field of academic global surgery. METHODS: We reviewed SciVerse SCOPUS, PubMed, African Medicus Index, African Journals Online (AJOL), SciELO, Latin American and Caribbean Health Sciences Literature (LILACS) and Bioline for manuscripts on global surgery curricula and evaluated the results using existing competency frameworks in global health and surgical education from Consortium of the Universities for Global Health (CUGH) and Accreditation Council for Graduate Medical Education (ACGME) professional competencies. RESULTS: Our search generated 250 publications, of which 18 were eligible: (1) a total of 10 reported existing competency-based curricula that were concurrent with international experiences, (2) two reported existing pre-departure competency-based curricula, (3) six proposed theoretical competency-based curricula for future global surgery education. All, but one, were based in high-income countries (HICs) and focused on the needs of HIC trainees. None met all 17 competencies, none cited the CUGH competency on "Health Equity and Social Justice" and only one mentioned "Social and Environmental Determinants of Health." Only 22% (n = 4) were available as open-access. CONCLUSION: Currently, there is no universally accepted set of competencies on the fundamentals of academic global surgery. Existing literature are predominantly by and for HIC institutions and trainees. Current frameworks are inadequate for this emerging academic field. The field needs competencies with explicit input from LMIC experts to ensure creation of educational resources that are accessible and relevant to trainees from around the world.

Building Trauma and EMS Systems Capacity in Rwanda: Lessons and Recommendations.

Background: Surgical capacity building has gained substantial momentum. However, care at the hospital level depends on improved access to emergency services. There is no established model for facilitating trauma and EMS system capacity in LMIC settings. This manuscript describes our model for multi-disciplinary collaboration to advance trauma and EMS capacity in Rwanda, along with our lessons and recommendations. Methods: After high-level meetings at the Ministry of Health in Rwanda (MOH), in 2016, a capacity building plan focusing on improved clinical services, quality improvement/research and leadership capacity across prehospital and emergency settings. The main themes for the collaborative model included for empowerment of staff, improving clinical service delivery, and investing in systems and infrastructure. Funding was sought and incorporated into the Sector Wide Approaches to Planning process at the Ministry of Health of Rwanda. Findings: A shared mental model was created through a fully funded immersion program for Rwandese leaders from emergency medicine, nursing, prehospital care, and injury policy. Prehospital care delivery was standardized within Kigali through a train-the-trainers program with four new context-appropriate short courses in trauma, medical, obstetric/neonatal, and pediatric emergencies and expanded across the country to reach >600 staff at district and provincial hospitals. Forty-two protocols and checklists were implemented to standardize prehospital care across specialties. The WHO Trauma Registry was instituted across four major referral centers in the country capturing over 5,000 injured patients. Long-term research capacity development included Masters' Degree support for 11 staff. Conclusions and Recommendations: This collaboration was highly productive in empowering staff and leadership, standardizing clinical service delivery in EMS, and investing in systems and infrastructure. This can be a useful model for trauma and EMS system capacity development in other LMICs.

Sepsis in two hospitals in Rwanda: A retrospective cohort study of presentation, management, outcomes, and predictors of mortality.

PURPOSE: Few studies have assessed the presentation, management, and outcomes of sepsis in low-income countries (LICs). We sought to characterize these aspects of sepsis and to assess mortality predictors in sepsis in two referral hospitals in Rwanda. MATERIALS AND METHODS: This was a retrospective cohort study in two public academic referral hospitals in Rwanda. Data was abstracted from paper medical records of adult patients who met our criteria for sepsis. RESULTS: Of the 181 subjects who met eligibility criteria, 111 (61.3%) met our criteria for sepsis without shock and 70 (38.7%) met our criteria for septic shock. Thirty-five subjects (19.3%) were known to be HIV positive. The vast majority of septic patients (92.7%) received intravenous fluid therapy (median = 1.0 L within 8 hours), and 94.0% received antimicrobials. Vasopressors were administered to 32.0% of the cohort and 46.4% received mechanical ventilation. In-hospital mortality for all patients with sepsis was 51.4%, and it was 82.9% for those with septic shock. Baseline characteristic mortality predictors were respiratory rate, Glasgow Coma Scale score, and known HIV seropositivity. CONCLUSIONS: Septic patients in two public tertiary referral hospitals in Rwanda are young (median age = 40, IQR = 29, 59) and experience high rates of mortality. Predictors of mortality included baseline clinical characteristics and HIV seropositivity status. The majority of subjects were treated with intravenous fluids and antimicrobials. Further work is needed to understand clinical and management factors that may help improve mortality in septic patients in LICs.

Development and Implementation of a Longitudinal Global Acute Care and Systems Strengthening Program.

BACKGROUND: Increasing access to safe, timely, and affordable acute care in low- and middle-income countries is a worldwide priority. Longitudinal curricula on systems of acute care have not been previously described. OBJECTIVES: The authors aimed to develop a novel four-year longitudinal curriculum for medical students addressing systems development across multiple acute care specialties. METHODS: The authors followed Kern's six-step framework for curriculum design. After review of literature, a group of medical students and school of medicine faculty conducted a targeted needs assessment. Foundational goals and objectives were adapted from the 39 interprofessional global health competencies by the Consortium of Universities for Global Health. Educational strategies include didactic sessions, workshops, journal clubs, preceptorships, and community outreach. Clinical years include specialty-specific emphases, guided junior-level discussions, and a capstone project. Yearly SWOT and Kirkpatrick model analyses served as program evaluation. FINDINGS: The Curriculum Council approved the program in July 2019. During the first cycle, the program matriculated 30 students from classes of 2023 (14) and 2022 (16). The first year produced 11 interactive sessions, 6 journal clubs, and 10 seminars led by 31 faculty and guest speakers; 29/30 students completed requirements; 87 evaluations reflected 4.57/5 content satisfaction and 4.73/5 instructor satisfaction. The 2023 cohort reported improved understanding of session objectives (3.13/5 vs. 3.82/5, p = 0.03). Free-text feedback led to implementation of pre-reading standardization and activity outlines. CONCLUSION: The Program was well-received and successfully implemented. It meets the needs of graduating medical students interested in leading global health work. This novel student-faculty collaborative model could be applied at other institutions seeking to provide students with a foundation in global acute care.

Prehospital emergency obstetric and neonatal care train-the-trainers program in Rwanda.

OBJECTIVE: To improve maternal mortality rates, our collaboration developed and implemented a context-specific, prehospital Emergency Obstetrics and Neonatal Course (EONC) and train-the-trainers program in Rwanda. METHODS: Two cohorts of staff participated in the program-the SAMU emergency medical service and staff from district hospitals. A 2-day course was developed, consisting of skills stations, simulations, and didactics. A 50-question assessment was administered to both cohorts before and after the courses. Student's t test and matched paired t tests were used to evaluate the assessments through retrospective analysis of the data. RESULTS: EONC1 median scores were 60% versus 92% (pre vs post), using matched-pair analysis of 20 participants. EONC2 median scores were 52% versus 96% (pre vs post), using matched-pair analysis of participants. A one-way analysis of variance mean square analysis showed that regardless of the baseline level of training for each participant, all trainees reached similar post-course assessment scores (F(1)  = 8.35, P = 0.0059). CONCLUSION: Optimal prehospital management of obstetric emergencies is essential to prevent needless mortality and morbidity. This study demonstrated that a context-appropriate prehospital obstetric and neonatal training program could be effectively developed and implemented for the SAMU team in Kigali, Rwanda.

The impact of data feedback on continuous quality improvement projects in Rwanda: A mixed methods analysis.

BACKGROUND: Injuries are a leading cause of death and disability globally. Over 90% of injury-related mortality happens in low- and middle- income countries (LMICs). Rwanda's pre-hospital emergency system - Service d'Aide Medicale Urgente (SAMU) - and their partners created an electronic pre-hospital registry and Continuous Quality Improvement (CQI) project in 2014. The CQI showed progress in quality of care, sparking interest in factors enabling the project's success. Healthcare workers (HCW) are critical pieces of this success, yet we found a void of information linking pre-hospital HCW motivation to CQI programs like SAMU's. METHODS: Our mixed methods approach included a 40-question survey using questions regarding HCW motivation. We scored the surveys to compare SAMU staff motivation with other HCWs in LMICs, and used a Likert scale to elicit agreement or disagreement. A semi-structured interview based on employee motivation theory qualitatively explored SAMU staff motivation using constructivist grounded theory. To find interview themes, two researchers independently performed line-by-line analysis. RESULTS: SAMU staff received 5-21% higher motivation scores relative to other cohorts of HCWs in LMICs. Questions showing disagreement (five) asked about reprimand, damaged social standing, and ease of using the CQI technology. Three questions did not show consensus. Questions showing agreement (23) and strong agreement (nine) asked about organizational commitment, impact, and research improving patient care. Major themes were: improvements in quality of care, changes in job expectations, views on research, and positive experiences with data feedback. CONCLUSIONS: The CQI project provides constant feedback vital to building and sustaining successful health systems. It encourages communication, collaboration, and personal investment, which increase organizational commitment. Continuous feedback provides opportunities for personal and professional development by uncovering gaps in knowledge, patient care, and technological understanding. Complete, personalized data input encouraged by the CQI improves resource allocation, building robust health systems that improve HCW agency and motivation.

Developing sustainable prehospital trauma education in Rwanda.

INTRODUCTION: Every year, >5 million people worldwide die from trauma. In Kigali, Rwanda, 50% of prehospital care provided by SAMU, the public prehospital system, is for trauma. Our collaboration developed and implemented a context-specific, prehospital Emergency Trauma Care Course (ETCC) and train-the-trainers program for SAMU, based on established international best practices. METHODS: A context-appropriate two-day ETCC was developed using established best practices consisting of traditional 30-minute lectures followed by 20-minute practical scenario-based team-driven simulation sessions. Also, hands-on skill sessions covered intravenous access, needle thoracostomy and endotracheal intubation among others. Two cohorts participated - SAMU staff who would form an instructor core and emergency staff from ten district, provincial and referral hospitals who are likely to respond to local emergencies in the community. The instructor core completed ETCC 1 and a one-day educator course and then taught the second cohort (ETCC2). Pre and post course assessments were conducted and analyzed using Student's t-test and matched paired t-tests. RESULTS: ETCC 1 had 17 SAMU staff and ETCC 2 had 19 hospital staff. ETCC 1 mean scores increased from 40% to 63% and ETCC 2 increased from 41% to 78% after the course (p < 0.001 using matched pair analysis). A one-way ANOVA mean square analysis showed that regardless of the baseline level of training for each participant, all trainees reached similar post-course assessment scores, F (1) = 15.18, p = 0.0004. DISCUSSION: This study demonstrates effective implementation of a context-appropriate prehospital trauma training program for prehospital staff in Kigali, Rwanda. The course resulted in improved knowledge for an instructor core and for staff from district and provincial hospitals confirming the effectiveness of a train-the-trainers model. This program may be effective to support capacity development for prehospital trauma care in the country using a qualified local source of instructors.

The Initial Prehospital Management of Traumatic Brain Injuries in Kigali, Rwanda.

INTRODUCTION: Traumatic brain injuries (TBIs) are an important cause of mortality and disability around the world. Early intervention and stabilization are necessary to obtain optimal outcomes, yet little is written on the topic in low- and middle-income countries (LMICs). The aim is to provide a descriptive analysis of patients with TBI treated by Service d'Aide Medicale Urgente (SAMU), the prehospital ambulance service in Kigali, Rwanda. HYPOTHESIS/PROBLEM: What is the incidence and nature of TBI seen on the ambulance in Kigali, Rwanda? METHODS: A retrospective descriptive analysis was performed using SAMU records captured on an electronic database from December 2012 through May 2016. Variables included demographic information, injury characteristics, and interventional data. RESULTS: Patients with TBIs accounted for 18.0% (n = 2,012) of all SAMU cases. The incidence of TBIs in Kigali was 234 crashes per 100,000 people. The mean age was 30.5 (SD = 11.5) years and 81.5% (n = 1,615) were men. The most common mechanisms were road traffic incidents (RTIs; 78.5%, n = 1,535), assault (10.7%, n=216), and falls (7.8%, n=156). Most patients experienced mild TBI (Glasgow Coma Score [GCS] ≥ 13; 83.5%, n = 1,625). The most common interventions were provision of pain medications (71.0%, n = 1,429), placement of a cervical collar (53.6%, n = 1,079), and administration of intravenous fluids (48.7%, n = 979). In total, TBIs were involved in 67.0% of all mortalities seen by SAMU. CONCLUSION: Currently, TBIs represent a large burden of disease managed in the prehospital setting of Kigali, Rwanda. These injuries are most often caused by RTIs and were observed in 67% of mortalities seen by SAMU. Rwanda has implemented several initiatives to reduce the incidence of TBIs with a specific emphasis on road safety. Further efforts are needed to better prevent these injuries. Countries seeking to develop prehospital care capacity should train providers to manage patients with TBIs.

Fostering Trauma and Emergency Research Capacity in Rwanda Through Collaboration.

OBJECTIVES: Access to effective emergent care would prevent 45% of all deaths in LMICs, however, trauma and emergency care remain largely neglected. Our collaboration in Rwanda to build prehospital trauma care led us to create a research mentorship program to enhance the ability of the local team to evaluate their system. METHODS: NIH grant funding had been previously obtained to establish standards for prehospital trauma care in Rwanda and build local research capacity. We created a research mentorship program that involved a surgical resident embedded locally tasked with 1) giving lectures on research, study design, interpretation, and writing, 2) providing mentorship for data interpretation and 3) supporting the development of abstracts, presentations, and publications. RESULTS: Four research teams identified high priority areas for quality improvement research. Research group meetings were held and involved mentored literature searches, critical review of published works, basics of study design, abstract writing and manuscript development. Abstracts were submitted and accepted to three international conferences. At this time 3 manuscripts have been accepted and are in production, 2 abstracts and 1 manuscript has been published. Eleven staff enrolled in master's degree programs in critical and nursing, epidemiology, public health and global health equity across three institutions. CONCLUSIONS: Responsive health care systems need capacity for ongoing quality improvement and research. This is especially true to address the massive global burden of disease of trauma and emergency conditions. US academic surgical collaborations have tremendous research expertise that can contribute to improving health system capacity globally. Such collaborations offer the opportunity to set up the foundations of future academic productivity.

Integrating a Novel Global Surgery and Health Inequity Course to the Surgical Clerkship.

OBJECTIVE: Medical students report growing interest in health inequity and global surgery, subjects not currently integrated to their core curriculum. Currently, fundamental tenets of global surgical inequity are only available to students on an elective basis or in special interest groups. Therefore, an hour-long course with emphasis on global surgery was developed for third-year medical students. The aim of this study was to examine student response to this pilot course and to establish whether course content was applicable to clinical rotations. DESIGN: A 1-hour structured curriculum was delivered to third-year medical students (MS3s) during the 2-day orientation phase of each rotation of an 8-week surgery clerkship from August 2018 to May 2019. The course targeted approximately 30 students per session in the preclinical orientation at Rutgers-New Jersey Medical School. Upon completion of the 8-week clerkship rotation, a paper survey was administered to evaluate student's exposure to previous content, attitudes toward global health, interest and engagement in course materials, and applicability of learned course content to local environments. SETTING: Rutgers-New Jersey Medical School, an urban medical school located in Newark, New Jersey. PARTICIPANTS: A total of 191 students attended the global surgery and health equity course; 146 participants participated in the postcourse survey. RESULTS: When asked about baseline interest in global or public health, the majority (51%) were extremely interested or very interested. Nearly all participants found the course to be valuable (94%). When asked which educational modality was preferred, 23% of participants favored the traditional lecture component and 29% favored case-based discussions. Nearly half (48%) the respondents found both modalities to be valuable. Fifty students (34% of respondents) reported encounters with patients affected by barriers in access to surgical care during their clerkships. CONCLUSIONS: Medical students responded favorably to this health inequity and global surgery pilot course and requested supplemental lectures. Additionally, course content was applicable to local clinical experiences. Therefore, 1 modality of integrating global surgery to the established curriculum is under the framework of health inequity and social determinants of health during surgical clerkships. This study demonstrates that meaningful inclusion of global surgery and health inequity can be implemented within the existing curricular structure.

Blunt cerebrovascular injury: The case for universal screening.

BACKGROUND: Current evidence-based screening algorithms for blunt cerebrovascular injury (BCVI) may miss more than 30% of carotid or vertebral artery injuries. We implemented universal screening for BCVI with computed tomography angiography of the neck at our level 1 trauma center, hypothesizing that only universal screening would identify all clinically relevant BCVIs. METHODS: Adult blunt trauma activations from July 2017 to August 2019 underwent full-body computed tomography scan including computed tomography angiography neck with a 128-slice computed tomography scanner. We calculated sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of common screening criteria. We determined independent risk factors for BCVI using multivariate analyses. RESULTS: A total of 4,659 patients fulfilled the inclusion criteria, 2.7% (n = 126) of which had 158 BCVIs. For the criteria outlined in the American College of Surgeons Trauma Quality Improvement Program Best Practices Guidelines, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 72.2%, 64.9%, 6.8%, 98.5%, and 65.2%, respectively; for the risk factors suggested in the more extensive expanded Denver criteria, they were 82.5%, 50.4%, 5.3%, 98.9%, and 51.4%, respectively. Twenty-three percent (n = 14) of patients with BCVI grade 3 or higher would not have been captured by any screening criteria. Cervical spine, facial, and skull base fractures were the strongest predictors of BCVI with odds ratios and 95% confidence intervals of 8.1 (5.4-12.1), 5.7 (2.2-15.1), and 2.7 (1.5-4.7), respectively. Eighty-three percent (n = 105) of patients with BCVI received antiplatelet agents or therapeutic anticoagulation, with 4% (n = 5) experiencing a bleeding complication, 3% (n = 4) a BCVI progression, and 8% (n = 10) a stroke. CONCLUSION: Almost 20% of patients with BCVI, including a quarter of those with BCVI grade 3 or higher, would have gone undiagnosed by even the most extensive and sensitive BCVI screening criteria. Implementation of universal screening should strongly be considered to ensure the detection of all clinically relevant BCVIs. LEVEL OF EVIDENCE: Diagnostic study, level III.

Prehospital epidemiology and management of injured children in Kigali, Rwanda.

INTRODUCTION: Paediatric injuries are a major cause of mortality and disability worldwide, yet little information exists regarding its epidemiology or prehospital management in low-income and middle-income countries. We aimed to describe the paediatric injuries seen and managed by the prehospital ambulance service, Service d'Aide Medicale d'Urgence (SAMU), in Kigali, Rwanda over more than 3 years. METHODS: A retrospective, descriptive analysis was conducted of all injured children managed by SAMU in the prehospital setting between December 2012 and April 2016. RESULTS: SAMU responded to a total of 636 injured children, 10% of all patients seen. The incidence of paediatric injury in Kigali, Rwanda was 140 injuries per 100 000 children. 65% were male and the average age 13.5 (±5.3). Most patients were between 15 and 19 years old (56%). The most common causes of injuries were road traffic incidents (RTIs) (447, 72%), falls (70, 11%) and assaults (50, 8%). Most RTIs involved pedestrians (251, 56%), while 15% (65) involved a bicycle. Anatomical injuries included trauma to the head (330, 52%), lower limb (280, 44%) and upper limb (179, 28%). Common interventions included provision of pain medications (445, 70%), intravenous fluids (217, 34%) and stabilisation with cervical collar (190, 30%). CONCLUSION: In Kigali, RTIs were the most frequent cause of injuries to children requiring prehospital response with most RTIs involving pedestrians. Rwanda has recently instituted several programmes to reduce the impact of paediatric injuries especially with regard to RTIs. These include changes in traffic laws and increased road safety initiatives.
