Organizing a virtual scientific conference: experiences from the Bethune Round Table 2021.

In response to the COVID-19 pandemic, organizations used virtual platforms to host academic meetings. This includes the Canadian Network for International Surgery and the Centre for Global Surgery at the McGill University Health Centre, who were tasked with organizing the Bethune Round Table (BRT), held May 28-31, 2021. With 496 registrants and 300 attendees representing 50 countries, the BRT 2021 was the most trafficked BRT conference in its 20-year history. One month after the conference's conclusion, attendees were continuing to view the recorded sessions. Here we describe the successes of the virtual BRT 2021 conference and the plan to continue offering a digital mode of delivery for future BRT conferences.

Identification and mitigation of high-risk pregnancy with the Community Maternal Danger Score Mobile Application in Gboko, Nigeria.

INTRODUCTION: Risk analyses within rural regions of Nigeria are not routinely conducted, yet could help inform access to skilled birth care. The objective of this study was to assess and compare the proportion of pregnant women at risk for maternal mortality or morbidity in Benue State, Nigeria by analysing data collected during routine antenatal visits and through the Community Maternal Danger Score (CMDS), a validated risk-analysis tool. METHODS: Two cohorts, comprised of pregnant women presenting to primary healthcare centres within Gboko, Benue State between 2015-2017 and 2020-2021, were included in this study. The 2015-2017 cohort had their risk assessed retrospectively through analysis of routinely collected data. Identification of risk was based on their age, parity, and disease status (HIV and diabetes). The 2020-2021 cohort had their risk assessed prospectively using the CMDS. RESULTS: Routinely collected data from 2015-2017 demonstrated that up to 14.9% of women in Gboko were at risk for mortality or morbidity. The CMDS reported that up to 21.5% of women were at a similar level of risk; a significant difference of 6.6% (p = 0.006). The CMDS was more efficient in obtaining and assessing this data, and the identification of risk occurred in real-time. CONCLUSION: Routine data collected in Gboko identifies a high proportion of pregnant women at risk for mortality or morbidity. The CMDS is an evidence-based risk analysis tool that expands on this assessment by also estimating individual and community-level risk, which allows for more efficient mitigation and prevention strategies of maternal mortality.

Clinical guideline utilization in Uganda: A scoping review and comparison.

Countries such as Uganda often depend on clinical practice guidelines from developed countries, non-profit charities, and international organizations. The sources and organizations that provide most of the guidelines used in Uganda are not well documented. The primary objective of this article was to determine whether a scoping review of scientific, peer-reviewed literature could identify the clinical guidelines actually used in Uganda. A secondary objective was to examine which organizations provided the majority of guidelines used. We therefore searched for consensus documents, guidelines, and meta-analyses published for use in African countries indexed in PubMed, OVID Medline, and Embase, and then surveyed guidelines currently in use in Ugandan medical practice. We thus compared these two sets of guidelines, as well as their breadth, geography, and sources, to make recommendations for similar low-income countries.

Assessment and validation of the Community Maternal Danger Score algorithm.

BACKGROUND: High rates of maternal mortality in low-and-middle-income countries (LMICs) are associated with the lack of skilled birth attendants (SBAs) at delivery. Risk analysis tools may be useful to identify pregnant women who are at risk of mortality in LMICs. We sought to develop and validate a low-cost maternal risk tool, the Community Maternal Danger Score (CMDS), which is designed to identify pregnant women who need an SBA at delivery. METHODS: To design the CMDS algorithm, an initial scoping review was conducted to identify predictors of the need for an SBA. Medical records of women who delivered at the Federal Medical Centre in Makurdi, Nigeria (2019-2020) were examined for predictors identified from the literature review. Outcomes associated with the need for an SBA were recorded: caesarean section, postpartum hemorrhage, eclampsia, and sepsis. A maternal mortality ratio (MMR) was determined. Multivariate logistic regression analysis and area under the curve (AUC) were used to assess the predictive ability of the CMDS algorithm. RESULTS: Seven factors from the literature predicted the need for an SBA: age (under 20 years of age or 35 and older), parity (nulliparity or grand-multiparity), BMI (underweight or overweight), fundal height (less than 35 cm or 40 cm and over), adverse obstetrical history, signs of pre-eclampsia, and co-existing medical conditions. These factors were recorded in 589 women of whom 67% required an SBA (n = 396) and 1% died (n = 7). The MMR was 1189 per 100,000 (95% CI 478-2449). Signs of pre-eclampsia, obstetrical history, and co-existing conditions were associated with the need for an SBA. Age was found to interact with parity, suggesting that the CMDS requires adjustment to indicate higher risk among younger multigravida and older primigravida women. The CMDS algorithm had an AUC of 0.73 (95% CI 0.69-0.77) for predicting whether women required an SBA, and an AUC of 0.85 (95% CI 0.67-1.00) for in-hospital mortality. CONCLUSIONS: The CMDS is a low-cost evidence-based tool that uses 7 risk factors assessed on 589 women from Makurdi. Non-specialist health workers can use the CMDS to standardize assessment and encourage pregnant women to seek an SBA in preparation for delivery, thus improving care in countries with high rates of maternal mortality.

The Kampala Trauma Score: A 20-year track record.

ABSTRACT: Quantifying the severity of traumatic injury has been foundational for the standardization of outcomes, quality improvement research, and health policy throughout the evolution of trauma care systems. Many injury severity scores are difficult to calculate and implement, especially in low- and middle-income countries (LMICs) where human resources are limited. The Kampala Trauma Score (KTS)-a simplification of the Trauma Injury Severity Score-was developed in 2000 to accommodate these settings. Since its development, numerous instances of KTS use have been documented, but extent of adoption is unknown. More importantly, does the KTS remain useful for determining injury severity in LMICs? This review aims to better understand the legacy of the KTS and assess its strengths and weaknesses. Three databases were searched to identify scientific papers concerning the KTS. Google Scholar was searched to identify grey literature. The search returned 357 papers, of which 199 met inclusion criteria. Eighty-five studies spanning 16 countries used the KTS in clinical settings. Thirty-seven studies validated the KTS, assessing its ability to predict outcomes such as mortality or need for admission. Over 80% of these studies reported the KTS equalled or exceeded more complicated scores at predicting mortality. The KTS has stood the test of time, proving itself over the last twenty years as an effective measure of injury severity across numerous contexts. We recommend the KTS as a means of strengthening trauma systems in LMICs and suggest it could benefit high-income trauma systems that do not measure injury severity.

Conducting an international curriculum review meeting in the age of COVID-19.

SUMMARY: The Canadian Network for International Surgery (CNIS) hosted a workshop in May of 2020 with a goal of critically evaluating Trauma Team Training courses. The workshop was held virtually because of the coronavirus disease 2019 (COVID-19) pandemic. Twenty-three participants attended from 8 countries: Canada, Guyana, Kenya, Nigeria, Switzerland, Tanzania, Uganda and the United States. More participants were able to attend the virtual meeting than the traditional in-person meetings. Web-based videoconference software was used, participants presented prerecorded PowerPoint videos, and questions were raised using a written chat. The review proved successful, with discussions and recommendations for improvements surrounding course quality, lecture content, skills sessions, curriculum variations and clinical practical scenarios. The CNIS's successful experience conducting an online curriculum review involving international participants may prove useful to others proceeding with collaborative projects during the COVID-19 pandemic.

Neurosurgery in East Africa: Innovations.

In the last 10 years, considerable work has been done to promote and improve neurosurgical care in East Africa with the development of national training programs, expansion of hospitals and creation of new institutions, and the foundation of epidemiologic and cost-effectiveness research. Many of the results have been accomplished through collaboration with partners from abroad. This article is the third in a series of articles that seek to provide readers with an understanding of the development of neurosurgery in East Africa (Foundations), the challenges that arise in providing neurosurgical care in developing countries (Challenges), and an overview of traditional and novel approaches to overcoming these challenges to improve healthcare in the region (Innovations). In this article, we describe the ongoing programs active in East Africa and their current priorities, and we outline lessons learned and what is required to create self-sustained neurosurgical service.

Examining perception and actual knowledge change among learners in a standardized burn course.

BACKGROUND: Essential Burn Management (EBM) is a burn training program created for East Africa and aims to meet the needs of low- and middle-income countries. The authors present a report on objective testing of change in knowledge, with pre and post tests, and comparison of this testing with the self perception of knowledge gained to explore course utility. OBJECTIVE: To evaluate the ability of EBM to improve knowledge in burn care among course participants; and to explore whether participants' self-perception of knowledge gained is comparable with their actual change in knowledge. METHODS: Twenty health care providers from a variety of disciplines participated in EBM and completed the pre and post course burn care knowledge test. Participants also self-rated knowledge in burn care both pre and post course. All tests and self-rated assessments were anonymous and consent was obtained. Paired t tests were conducted on pre and post test scores. Improvements in pre-post scores according to module or topic area were examined to determine the proportion correct, and then analyzed using Wilcoxon signed-rank tests. Module scores pre-post course were compared with individuals' self-rating of knowledge both before and after the course for that particular module. RESULTS: Pre-post course tests reflected an increase in knowledge. An increase in self-rated knowledge was matched with a significant increase in module test scores for primary survey, burn resuscitation, wound management, infection control and electrical injury, but not inhalation injury and compartment syndrome modules. CONCLUSION: Findings support a combination of self-report and objective pre-post testing to evaluate courses designed to teach burn management.

HISTORIQUE: La gestion essentielle des brûlures (GEB) est un programme de formation sur les brûlures créé pour l'Afrique de l'Est afin de répondre aux besoins des pays à faible et moyen revenu. Les auteurs présentent un rapport sur les tests objectifs d'acquisition des connaissances, au moyen de tests avant-après, et les comparent aux perceptions des connaissances acquises pour explorer l'utilité du cours. OBJECTIF: Évaluer la capacité de la GEB à améliorer les connaissances des participants au cours sur les soins des brûlures et explorer si les perceptions des connaissances qu'ils ont acquises sont comparables au véritable changement de connaissances. MÉTHODOLOGIE: Vingt dispensateurs de soins de diverses disciplines ont participé à la GEB et effectué le test avant-après sur les connaissances des brûlures. Les participants ont également autoévalué leurs connaissances sur les soins des brûlures avant et après le cours. Les tests et les autoévaluations étaient tous anonymes, et les participants avaient donné leur consentement. Les cher-cheurs ont effectué des tests t d'échantillons appariés sur les scores aux tests avant-après. Ils ont examiné les améliorations aux scores avant-après selon le module ou le sujet pour déterminer la proportion de bons résultats, puis les ont analyséses selon les tests d'appariement des données de Wilcoxon. Ils ont comparé les scores des modules avant-après à l'autoévaluation des connaissances avant et après le cours pour chaque module. RÉSULTATS: Les tests avant-après reflètent une augmentation des connaissances. Une augmentation des connaissances autoévaluées correspondait à un accroissement important des points accumulés lors des tests des modules sur l'évaluation primaire, la réanimation des brûlés, le traitement des plaies, le contrôle des infections et les blessures électriques, mais pas de ceux sur les blessures par inhalation et le syndrome des loges. CONCLUSION: Les observations appuient une combinaison d'autodéclaration et de tests avant-après objectifs pour évaluer les cours sur la gestion des brûlures.

Creation of a standardized burn course for Low Income Countries: meeting local needs.

INTRODUCTION: Standardized courses for the care of the burn patient have historically been developed in High Income Countries (HIC). These courses do not necessarily reflect the challenges and needs of Low Income Countries (LIC) and some components may not be relevant there (i.e. use of ventilators in a country that has no or very limited number of ventilators). We are developing a Burn Management Course for East Africa. This course was created and trialed in a LIC and subsequently a formal manual and course curriculum created. Recently the first iteration of the course was undertaken in a major regional burn centre in East Africa. We present participant feedback on the course content, and potential future directions for course development. OBJECTIVE: (1) To evaluate the ability of a standardized burn course for LIC to meet the needs of the participants. (2) To explore characteristics of burn care and needs related to delivery of burn care in LIC. METHODS: 21 students participated in a multidisciplinary burn management course. They were asked to complete an anonymous questionnaire at the end of the course. RESULTS: There were 11 nurses, 6 doctors, a physiotherapist, occupational therapist, and a dietician. 15 worked in either the adult or pediatric burn units, the other six worked in emergency, ICU or the operating room. The majority of respondents (56%) had less than 3 years of experience working with burn patients. Overall agreement that the course met their objectives was rated as 4.6 out of 5. As well the students agreement that they had a better understanding of burn injury was rated as 4.8/5. 55.6% indicated that scalds were the most commonly seen injury followed by 27.8% responding that flames were the most common. Some responses to the question of top difficulties facing the caregivers were similar to HIC: staffing shortages, bed shortages, and finding useable donor site in large burns. Other responses highlighted the challenges these care givers face: poverty stricken patients, not enough appropriate food available, and deficiencies in infection control practices. CONCLUSION: It is possible to create a course that translates knowledge from a HIC setting to meet the needs of the end-user in a LIC setting.

Occupational injuries and fatalities in a tanzanite mine: Need to improve workers safety in Tanzania.

INTRODUCTION: Work related injuries are common, and the mining industry accounts for a significant proportion of these injuries. Tanzania is among the countries with high rates of mining injuries, nevertheless pre-hospital care is almost non existant and health care service deliveries are poor. This study sought to identify factors associated with injuries and fatalities among miners in Mererani, Tanzania. METHODS: A Cross - Sectional study of miners who sustained injuries and seen at Mererani health centre between January 2009 and May 2012. RESULTS: In the selected period 248 injury patients were seen. All were males, and 54% were between 18 - 30 years age-group. Almost all (98.7%) didn't use protective gears at work, and worked for more than 12 hours daily. Falling rocks were the leading cause of injury (18.2%), and majority sustained multiple injuries (33%). Of the patients seen, 41.3% died. The following were more likely to die than others; Primary education (p = 0.04), Less than 5 years work experience (p = 0.000), unintentional injuries (p = 0.000), fall injuries (p = 0.000) and sustaining multiple injuries (p = 0.000). CONCLUSION: The burden of injuries and fatalities demonstrated in this study, point to the need for implementation and monitoring of the use of safety equipment and operating procedures of the mines by government and other regulatory authorities. Initiation of pre hospital care at the mines and improved emergency medical service delivery at health centers in Tanzania.

Intentional injuries among Ugandan youth: a trauma registry analysis.

PURPOSE: To determine intentional injury burden, incident characteristics, and outcomes among Ugandan youth. METHODS: A cross sectional analysis of trauma registry data from accident and emergency units of five regional referral hospitals was conducted. Data had been prospectively collected from all patients accessing injury care at the five sites between July 2004 and June 2005: youth records were analysed. RESULTS: Intentional injuries among youth victims, especially school-age males, are common in all five regions, constituting 7.3% of their injury burden with a male dominance. Intentional youth victimisation mainly occurred at home, on roads, and in public places; incidents were largely due to blunt force, stabs/cuts, and gunshots in general, although variations in causes were evident depending on age. Intentional injuries among the youth victims often manifested as head, neck, and face injuries: 2% were severe and there were 4%case fatalities at 2 weeks. CONCLUSIONS AND RECOMMENDATIONS: Intentional injuries among youth victims, especially school-age males, are important contributors of injury burden in all five sites. Homes, roads, and public places are unsafe for Ugandan youth. Although guns were used in all five sites, less lethal mechanisms (blunt force, stabs/cuts, and burns) are the most common with variations between locations. Incidents involving teenage housewives could reflect underlying problem of domestic violence. Community based studies could be highly informative. Youth should be prioritised for prevention of injuries both in and out of school.

Injury in Kampala, Uganda: 6 years later.

BACKGROUND: Trauma remains a tremendous cause of morbidity and mortality in most countries. The objective of our study was to describe injury from trauma at the major referral hospital in Uganda over a 1-year period. METHODS: Trauma registry forms have been completed for all trauma patients seen between August 2004 and July 2005 at the casualty department of Mulago Hospital in Kampala, Uganda. We also obtained 2-week follow-up data, and we compared these data with 1998 data from the same institution. RESULTS: In all, 3778 patients were entered into the database, with complete data available for 93.5% of patients. Patients had a mean age of 26 (standard deviation [SD] 12) years, and 75% of patients were male. The mean Kampala Trauma Score (KTS) was 9.1 (SD 1). We classified injuries as mild (82%; KTS 9-10), moderate (14%; KTS 7-8) and severe (4%; KTS

Assessing the impact of the trauma team training program in Tanzania.

BACKGROUND: In sub-Saharan Africa, injury is responsible for more deaths and disability-adjusted life years than AIDS and malaria combined. The trauma team training (TTT) program is a low-cost course designed to teach a multidisciplinary team approach to trauma evaluation and resuscitation. The purpose of this study was to assess the impact of TTT on trauma knowledge and performance of Tanzanian physicians and nurses; and to demonstrate the validity of a questionnaire assessing trauma knowledge. METHODS: This is a prospective study of physicians and nurses from Dar es Salaam undergoing TTT (n = 20). Subjects received a precourse test and, after the course, an alternate postcourse test. The equivalence and construct validity of these 15-item multiple-choice questionnaires was previously demonstrated. After the course, subjects were divided into four teams and underwent a multiple injuries simulation, which was scored with a trauma resuscitation simulation assessment checklist. A satisfaction questionnaire was then administered. Test data are expressed as median score (interquartile ratio) and were analyzed with the Wilcoxon's signed rank test. RESULTS: After the TTT course, subjects improved their scores from 9 (5-12) to 13 (9-13), p = 0.0004. Team performance scores for the simulation were all >80%. Seventy-five percent of subjects were very satisfied with TTT and 90% would strongly recommend it to others and would agree to teach future courses. CONCLUSIONS: After completion of TTT, there was a significant improvement in trauma resuscitation knowledge, based on results from a validated questionnaire. Trauma team performance was excellent when assessed with a novel trauma simulation assessment tool. Participants were very supportive of the course.

Pedestrian traffic injuries among school children in Kawempe, Uganda.

BACKGROUND: Traffic injuries are an important problem in low income countries. In Uganda road traffic is the largest single cause of injury in Kampala; pedestrians, and children are most affected. Pedestrian injury affects school children in Uganda. OBJECTIVE: To determine the overall risk of pedestrian traffic injury among school children in Kawempe, Uganda. METHODS: A cohort was assembled at 35 primary schools and followed for 3 terms. Ten of the schools had participated in previous injury programs, others were systematically selected. Injuries were recorded by teachers using a questionnaire. Data collected included ID, school, age, grade, gender, incident date, vehicle type, and injury outcome. Demographic characteristics are described and cumulative incidences calculated. RESULTS: The cohort included 8,165 children (49% male) from 35 primary schools. The mean age was 9 years (Sd=2.78). Of the 35 schools, 92% were day; the others mixed day and boarding. 53 children (27 girls) were involved in a traffic incident. 25% of the injuries reported were serious and warranted care in a health facility. No deaths occurred. Forty % of incidents involved commercial motorcycles, 41% bicycles, 9% cars, 8% taxis, and 2% trucks. The cumulative incidence was 0.168% each term. Over the 3 terms of the year the cumulative incidence was 0.5 +/- 0.02. There were no gender differences in the cumulative incidence. CONCLUSION: Each school year about 1/2 % of Kawempe school children are involved in a traffic incident. Interventions are necessary to reduce the unacceptably high incidents of pedestrian traffic. Interventions to alleviate this situation including safer routes, teaching skills of road crossing to children as well as better regulation and road safety education to two wheelers could reduce the unacceptably high incidents of pedestrian traffic injury.

Burden of injury during the complex political emergency in northern Uganda.

BACKGROUND: War injury is a public health problem that warrants global attention. This study aims to determine the burden of injury during a complex emergency in sub-Saharan Africa. METHODS: To determine the magnitude, causes, distribution, risk factors and cumulative burden of injury in a population experiencing armed conflict in northern Uganda since 1986 and to evaluate the living conditions and access to care for injury victims, we took a multistage, stratified, random sampling from the Gulu district to determine the rates of injury from 1994 to 1999. The Gulu district is endemic for malaria, tuberculosis, HIV and malnutrition and has a high maternal death rate. It is 1 of 3 districts in northern Uganda affected by war since 1986. The study participants included 8595 people from 1475 households. Of these, 73.0% lived in temporary housing, 46.0% were internally displaced and 81.0% were under 35 years of age. Trained interviewers administered a 3-part household survey in the local language. Quantitative data on injury, household environment, health care and demography were analyzed. Qualitative data from part 3 of the survey will be reported elsewhere. A similar rural district (Mukono) not affected by war was used for comparison. We studied injury risk factors, mortality and disability rates, accumulated deaths, access to care and living conditions. RESULTS: Of the study population, 14% were injured annually: gunshot injuries were the leading cause of death. The annual death rate from war injury was 7.8/1000 (95% confidence interval [CI] 7.0-8.5) and the disability rate was 11.3/1000 (95% CI 10.4-12.2). The annual excess injury mortality was 6.85/1000. Only 4.5% of the injured were combatants. Fifty percent of the injured received first aid, but only 13.0% of those who died reached hospital. The injury mortality in Gulu was 8.35-fold greater than that for Mukono. CONCLUSIONS: The crisis in Gulu can be considered a complex political emergency. Protracted conflicts should not be ignored because of a low rate of injury death since the cumulative total is high. Political emergencies should be monitored, and when the mortality exceeds 3.5%, international intervention is indicated. The international and national failings of this protracted conflict should be critically analyzed so that such political emergencies can be prevented or terminated.

International surgery: definition, principles and Canadian practice.

This article is dedicated to the Canadian international surgeon, Norman Bethune (1890-1939). International surgery is defined as a humanitarian branch of medicine concerned with the treatment of bodily injuries or disorders by incision or manipulations, emphasizing cooperation and understanding among nations and involving education, research, development and advocacy. In this article I review the colonial past, the dark ages following the Declaration of Alma-Ata, the progress made and the present challenges in international surgery. I present a definition of international surgery that recognizes the current era of surgical humanitarianism, validates a global understanding of surgical issues and promotes cooperation among nations. Included are the principles of international surgery: education, research, infrastructure development and advocacy. International surgical projects are classified according to type (clinical, relief, developmental) and integration strategy (vertical or horizontal). Also reviewed are the Canadian practice of international surgery by nongovernmental, professional and academic organizations and the requirements of international and Canadian funding agencies, the development concepts basic to all projects, including results-based management and the cross-cutting themes of gender equity, environmental protection and human safety. I recommend formalizing international surgery into a discipline as a means of promoting surgical care in low-income countries. If international surgery is to be sustained in Canada, infrastructure and support from Canadian surgeons is particularly important. An understanding of the history, definition and classification of international surgery should promote surgical care in low-income countries.

A unified framework for injury control: the public health approach and Haddon's Matrix combined.

Injury specialists have not successfully convinced policy makers and the public that injuries can be controlled. That failure may be due in part to the lack of a unified understanding of injury control. The two most important models utilized in injury control are Haddon's Matrix and the Public Health Approach (PHA). This paper argues that the PHA should be combined with the two axes of Haddon's Matrix to result in a model that is coherent and comprehensive. Thus it is better than either one of the original models on their own. Haddon's Matrix has two axes. The first includes elements of the epidemiological triad, host, vector, and environment and likens injury to disease. The second axis includes three time intervals, pre-event, event, and post-event. The importance of including time was that injury was conceptualized as predictable and preventable. The weakness of Haddon's matrix is that it lacks a systematic plan of action. The Public Health Approach is a methodology for addressing injury, which consists of a hierarchy of four levels; surveillance, risk factor identification, intervention evaluation and program implementation. The use of the PHA with no specific orientation or means of application is its weakness. The PHA lacks a systematic point of application. Haddon's Matrix lacks a systematic action plan. Therefore we propose the PHA as the systematic strategy for the more theoretical framework of Haddon's matrix. By combining these concepts a coherent and comprehensive three-dimensional framework is defined. The unified model closes the potential gaps in the two original models and includes a systematic approach not previously achieved. This unified model is practical in defining individual studies and groups of studies. It can be used as an inventory, for a complete understanding of a particular injury. Diagrams of the model are presented to help teach the concepts of injury described in this unitary model. In conclusion, we can say that the inclusion of three injury concepts in one framework provides a rigorous and coherent construct for the understanding of injury and implementation of control activities. It can therefore be used to design more comprehensive programs for injury control and promote policies and funding commensurate with the magnitude of the injury problem.
