RESUMEN

Problem: The fragmented health sector in Somalia, burdened by financial challenges and an inadequate regulatory system, struggles to provide equitable essential health services to the entire population. Approach: To revise an essential package of health services that stakeholders could support and that aligned with stakeholders' financial and technical resources, the federal health ministry invited all key stakeholders in 2020 to participate in the revision process of the essential package. The ministry distributed a concept note to invited stakeholders, describing the scope and purpose of the revision process of the essential package. The note also contained a timeline and the expected contribution of each stakeholder. Stakeholders nominated representatives based on their technical expertise and knowledge of the health sector in Somalia. Local setting: The health sector in Somalia involves multiple stakeholders, including the health ministry and many development partners. The private sector plays a substantial role in health-care provision. Public spending is an estimated 17% of the total health expenditure. Relevant changes: After an 18-month revision process, the health ministry and development partners agreed to prioritize high-impact, cost-effective services and use a progressive realization of the package to improve access and coverage. The implementation strategy considers the health system and operational capacity of service providers, particularly in security-compromised areas. Lessons learnt: The approach showed that inclusivity, collaboration and transparency were of importance for a successful revision of the package. These achievements in consensus-building and priority alignment advance the government's pursuit of equitable and comprehensive health care for all.

RESUMEN

BACKGROUND: A multitude of operative trauma courses exist, most of which are designed for and conducted in high-resource settings. There are numerous barriers to adapting such courses to low- and low-middle-income countries (LMICs), including resource constraints and contextual variations in trauma care. Approaches to implementing operative trauma courses in LMICs have not been evaluated in a structured manner. METHODS: We conducted a scoping review of the literature including databases (e.g., PubMed, Web of Science, EMBASE), grey literature repositories, and structured queries of publicly available course materials to identify records that described operative trauma courses offered since 2000. RESULTS: The search identified 3,518 non-duplicative records, of which 48 relevant reports were included in analysis. These reports represented 23 named and 11 unnamed operative trauma courses offered in 12 countries. Variability existed in course format and resource requirements, ranging from USD 40 to 3,000 per participant. Courses incorporated didactic and laboratory components, which utilized simulations, cadavers, or live animals. Course content overlapped significantly but was not standardized. Data were lacking on course implementation and promulgation, credentialing of instructors, and standardized evaluation metrics. CONCLUSIONS: While many operative trauma courses have been described, most are not directly relatable to LMICs. Barriers include cost-prohibitive fees, lack of resources, limited data collection, and contextual variability that renders certain surgical care inappropriate in LMICs. Gaps exist in standardization of course content as well as transparency of credentialing and course implementation strategies. These issues can be addressed through developing an open-access operative trauma course for low-resource settings.

RESUMEN

BACKGROUND: Indicators to evaluate progress towards timely access to safe surgical, anaesthesia, and obstetric (SAO) care were proposed in 2015 by the Lancet Commission on Global Surgery. These aimed to capture access to surgery, surgical workforce, surgical volume, perioperative mortality rate, and catastrophic and impoverishing financial consequences of surgery. Despite being rapidly taken up by practitioners, data points from which to derive the indicators were not defined, limiting comparability across time or settings. We convened global experts to evaluate and explicitly define-for the first time-the indicators to improve comparability and support achievement of 2030 goals to improve access to safe affordable surgical and anaesthesia care globally. METHODS AND FINDINGS: The Utstein process for developing and reporting guidelines through a consensus building process was followed. In-person discussions at a 2-day meeting were followed by an iterative process conducted by email and virtual group meetings until consensus was reached. The meeting was held between June 16 to 18, 2019; discussions continued until August 2020. Participants consisted of experts in surgery, anaesthesia, and obstetric care, data science, and health indicators from high-, middle-, and low-income countries. Considering each of the 6 indicators in turn, we refined overarching descriptions and agreed upon data points needed for construction of each indicator at current time (basic data points), and as each evolves over 2 to 5 (intermediate) and >5 year (full) time frames. We removed one of the original 6 indicators (one of 2 financial risk protection indicators was eliminated) and refined descriptions and defined data points required to construct the 5 remaining indicators: geospatial access, workforce, surgical volume, perioperative mortality, and catastrophic expenditure. A strength of the process was the number of people from global institutes and multilateral agencies involved in the collection and reporting of global health metrics; a limitation was the limited number of participants from low- or middle-income countries-who only made up 21% of the total attendees. CONCLUSIONS: To track global progress towards timely access to quality SAO care, these indicators-at the basic level-should be implemented universally as soon as possible. Intermediate and full indicator sets should be achieved by all countries over time. Meanwhile, these evolutions can assist in the short term in developing national surgical plans and collecting more detailed data for research studies.

RESUMEN

BACKGROUND: There is a pressing need for emergency care (EC) training in low-resource settings. We assessed the feasibility and acceptability of training frontline healthcare providers in emergency care with the World Health Organization (WHO)-International Committee of the Red Cross (ICRC) Basic Emergency Care (BEC) Course using a training-of-trainers (ToT) model with local providers. METHODS: Quasiexperimental pretest and post-test study of an educational intervention at four first-level district hospitals in Tanzania and Uganda conducted in March and April of 2017. A 2-day ToT course was held in both Tanzania and Uganda. These were immediately followed by a 5-day BEC Course, taught by the newly trained trainers, at two hospitals in each country. Both prior to and immediately following each training, participants took assessments on EC knowledge and rated their confidence level in using a variety of EC skills to treat patients. Qualitative feedback from participants was collected and summarised. RESULTS: Fifty-nine participants completed the four BEC Courses. All participants were current healthcare workers at the selected hospitals. An additional 10 participants completed a ToT course. EC knowledge scores were significantly higher for participants immediately following the training compared with their scores just prior to the training when assessed across all study sites (Z=6.23, p<0.001). Across all study sites, mean EC confidence ratings increased by 0.74 points on a 4-point Likert scale (95% CI 0.63 to 0.84, p<0.001). Main qualitative feedback included: positive reception of the sessions, especially hands-on skills; request for additional BEC trainings; request for obstetric topics; and need for more allotted training time. CONCLUSIONS: Implementation of the WHO-ICRC BEC Course by locally trained providers was feasible, acceptable and well received at four sites in East Africa. Participation in the training course was associated with a significant increase in EC knowledge and confidence at all four study sites. The BEC is a low-cost intervention that can improve EC knowledge and skill confidence across provider cadres.

RESUMEN

OBJECTIVE: To systematically review and appraise the quality of cost-effectiveness analyses of emergency care interventions in low- and middle-income countries. METHODS: Following the PRISMA guidelines, we systematically searched PubMed®, Scopus, EMBASE®, Cochrane Library and Web of Science for studies published before May 2019. Inclusion criteria were: (i) an original cost-effectiveness analysis of emergency care intervention or intervention package, and (ii) the analysis occurred in a low- and middle-income setting. To identify additional primary studies, we hand searched the reference lists of included studies. We used the Consolidated Health Economic Evaluation Reporting Standards guideline to appraise the quality of included studies. RESULTS: Of the 1674 articles we identified, 35 articles met the inclusion criteria. We identified an additional four studies from the reference lists. We excluded many studies for being deemed costing assessments without an effectiveness analysis. Most included studies were single-intervention analyses. Emergency care interventions evaluated by included studies covered prehospital services, provider training, treatment interventions, emergency diagnostic tools and facilities and packages of care. The reporting quality of the studies varied. CONCLUSION: We found large gaps in the evidence surrounding the cost-effectiveness of emergency care interventions in low- and middle-income settings. Given the breadth of interventions currently in practice, many interventions remain unassessed, suggesting the need for future research to aid resource allocation decisions. In particular, packages of multiple interventions and system-level changes represent a priority area for future research.

RESUMEN

BACKGROUND: In Tanzania, there is no national trauma registry. The World Health Organization (WHO) has developed a data set for injury that specifies the variables necessary for documenting the burden of injury and patient-related clinical processes. As a first step in developing and implementing a national Trauma Registry, we determined how well hospitals currently capture the variables that are specified in the WHO injury set. METHODS: This was a prospective, observational cross-sectional study of all trauma patients conducted in the Emergency Units of five regional referral hospitals in Tanzania from February 2018 to July 2018. Research assistants observed the provision of clinical care in the EU for all patients, and documented performed assessment, clinical interventions and final disposition. Research assistants used a purposefully designed case report form to audit the injury variable capture rate, and to review Ministry of Health (MoH) issued facility Register book recording the documentation of variables. We present descriptive statistics for hospital characteristics, patient volume, facility infrastructure, and capture rate of trauma variables. RESULTS: During the study period, 2891 (9.3%) patients presented with trauma-related complaints, 70.7% were male. Overall, the capture rate of all variables was 33.6%. Documentation was most complete for demographics 71.6%, while initial clinical condition, and details of injury were documented in 20.5 and 20.8% respectively. There was no documentation for the care prior to Emergency Unit arrival in all hospitals. 1430 (49.5%) of all trauma-related visits seen were documented in the facility Health Management Information System register submitted to the MoH. Among the cases reported in the register book, the date of EU care was correctly documented in 77% cases, age 43.6%, diagnosis 66.7%, and outcome in 38.9% cases. Among the observed procedures, initial clinical condition (28.7%), interventions at Emergency Unit (52.1%), investigations (49.0%), and disposition (62.9%) were documented in the clinical charts. CONCLUSIONS: In the regional hospitals of Tanzania, there is inadequate documentation of the minimum trauma variables specified in the WHO injury data set. Reasons for this are unclear, but will need to be addressed in order to improve documentation to inform a national injury registry.

RESUMEN

BACKGROUND: More than half of deaths in low- and middle-income countries (LMICs) result from conditions that could be treated with emergency care - an integral component of universal health coverage (UHC) - through timely access to lifesaving interventions. METHODS: The World Health Organization (WHO) aims to extend UHC to a further 1 billion people by 2023, yet evidence supporting improved emergency care coverage is lacking. In this article, we explore four phases of a research prioritisation setting (RPS) exercise conducted by researchers and stakeholders from South Africa, Egypt, Nepal, Jamaica, Tanzania, Trinidad and Tobago, Tunisia, Colombia, Ethiopia, Iran, Jordan, Malaysia, South Korea and Phillipines, USA and UK as a key step in gathering evidence required by policy makers and practitioners for the strengthening of emergency care systems in limited-resource settings. RESULTS: The RPS proposed seven priority research questions addressing: identification of context-relevant emergency care indicators, barriers to effective emergency care; accuracy and impact of triage tools; potential quality improvement via registries; characteristics of people seeking emergency care; best practices for staff training and retention; and cost effectiveness of critical care - all within LMICs. CONCLUSIONS: Convened by WHO and facilitated by the University of Sheffield, the Global Emergency Care Research Network project (GEM-CARN) brought together a coalition of 16 countries to identify research priorities for strengthening emergency care in LMICs. Our article further assesses the quality of the RPS exercise and reviews the current evidence supporting the identified priorities.

RESUMEN

BACKGROUND: Tanzania has witnessed several disasters in the past decade, which resulted in substantial mortality, long-term morbidity, and significant socio-economic losses. Health care facilities and personnel are critical to disaster response. We assessed the current state of disaster preparedness and response capacity among Tanzanian regional hospitals. METHODS: This descriptive cross-sectional survey was conducted in all Tanzanian regional hospitals between May 2012 and December 2012. Data were prospectively collected using a structured questionnaire based on the World Health Organization National Health Sector Emergency Preparedness and Response Tool. Trained medical doctors conducted structured interviews and direct observations in each hospital. RESULTS: We surveyed 25 regional hospitals (100% capture) in mainland Tanzania, in which interviews were conducted with 13-hospital doctors incharge, 9 matrons and 4 heads of casualty. All the hospitals were found to have inadequate numbers of all cadres of health care providers to support effective disaster response. 92% of hospitals reported experiencing a disaster in the past 5 years; with the top three being large motor vehicle accidents 22 (87%), floods 7 (26%) and infectious disease outbreaks 6 (22%). Fifteen hospitals (60%) had a disaster committee, but only five (20%) had a disaster plan. No hospital had all components of surge capacity. Although all had electricity and back-up generators, only 3 (12%) had a back-up communication system. CONCLUSION: This nationwide survey found that hospital disaster preparedness is at an early stage of development in Tanzania, and important opportunities exist to better prepare regional hospitals to respond to disasters.

RESUMEN

STUDY OBJECTIVE: We describe ketamine procedural sedations and associated adverse events in low-acuity and high-acuity patients in a resource-limited ED. METHODS: This was a prospective observational study of ketamine procedural sedations at the Emergency Medical Department at the Muhimbili National Hospital in Dar es Salaam, Tanzania. We observed consecutive procedural sedations and recorded patient demographics, medications, vital signs, pulse oximetry, capnography and a priori defined adverse events (using standard definitions in emergency medicine sedation guidelines). All treatment decisions were at the discretion of the treating providers who were blinded to study measurements to simulate usual care. Data collection was unblinded if predefined safety parameters were met. For all significant adverse and unblinding events, ketamine causality was determined via review protocol. Additionally, providers and patients were assessed for sedation satisfaction. RESULTS: We observed 54 children (median 3 years, range 11 days-15 years) and 45 adults (median 33 years, range 18-79 years). The most common indications for ketamine were burn management in children (55.6%) and orthopaedic procedures in adults (68.9%). Minor adverse events included nausea/vomiting (12%), recovery excitation (11%) and one case of transient hypertension. There were nine (9%) patients who had decreased saturation readings (SpO2 ≤92%). There were three deaths, all in severely injured patients. After review protocol, none of the desaturations or patient deaths were thought to be caused by ketamine. No patient experienced ketamine-related laryngospasm, apnoea or permanent complications. Overall, ketamine was well tolerated and resulted in high patient and provider satisfaction. CONCLUSION: In this series of ketamine sedations in an urban, resource-limited ED, there were no serious adverse events attributable to ketamine.

RESUMEN

Injury is a leading cause of death globally, and organized trauma care systems have been shown to save lives. However, even though most injuries occur in low- and middle-income countries (LMICs), most trauma care research comes from high-income countries where systems have been implemented with few resource constraints. Little context-relevant guidance exists to help policy makers set priorities in LMICs, where resources are limited and where trauma care may be implemented in distinct ways. We have aimed to review the evidence on the impact of trauma care systems in LMICs through a systematic search of 11 databases. Reports were categorized by intervention and outcome type and summarized. Of 4,284 records retrieved, 71 reports from 32 countries met inclusion criteria. Training, prehospital systems, and overall system organization were the most commonly reported interventions. Quality-improvement, costing, rehabilitation, and legislation and governance were relatively neglected areas. Included reports may inform trauma care system planning in LMICs, and noted gaps may guide research and funding agendas.

RESUMEN

BACKGROUND: Trauma contributes significantly to the burden of disease and mortality throughout the world, but particularly in developing countries. In Tanzania, there is an enormous research gap on trauma; the limited data available reflects realities in cities and areas with moderately- to highly-resourced treatment centers. Our aim was to provide a description of the injury epidemiology across all of Tanzania. Our data will serve as a basis for future larger studies. METHODS: This is a subgroup analysis of a cross-sectional, prospective study of the clinical epidemiology of patients presenting at all public district and regional hospitals in Tanzania. The study was conducted between May 2012 and December 2012. A team of emergency doctors used a purpose-designed data collection sheet to gather the demographic and clinical information of all patients presenting during the day-site visit to each hospital. Descriptive statistics, including means, standard deviations, medians, and ranges are reported. RESULTS: A total of 5227 patients were seen in 24-h period in 105 (100% response rate) district (or designated district) and regional hospitals in mainland Tanzania. Of these patients, 508 (9.7%) presented with trauma-related complaints. Among patients with trauma-related complaints, 286 (56.3%) were male, and the overall median age of 30 (interquartile range of 22-35) years. Road traffic crash was the most common mechanism of injury, accounting for 227 (44.7%) complaints. Open wounds and bone fractures were the two most frequent diagnoses, with a combined 300 (59%) cases. Most of the patients - 325 (64%) - were discharged, 11 (2.2%) went to operating theatres and 4 (0.8%) of patients died while receiving care at the acute intake areas. CONCLUSIONS: Trauma-related complaints constitute a substantial burden among patients seeking care in acute intake areas of hospitals across Tanzania. There is a need to develop, implement and study systems that can support the improvement of trauma care and optimize outcomes of trauma patients.

RESUMEN

OBJECTIVE: To understand the degree to which the trauma care guidelines released by the World Health Organization (WHO) between 2004 and 2009 have been used, and to identify priorities for the future implementation and dissemination of such guidelines. METHODS: We conducted a systematic review, across 19 databases, in which the titles of the three sets of guidelines - Guidelines for essential trauma care, Prehospital trauma care systems and Guidelines for trauma quality improvement programmes - were used as the search terms. Results were validated via citation analysis and expert consultation. Two authors independently reviewed each record of the guidelines' implementation. FINDINGS: We identified 578 records that provided evidence of dissemination of WHO trauma care guidelines and 101 information sources that together described 140 implementation events. Implementation evidence could be found for 51 countries - 14 (40%) of the 35 low-income countries, 15 (32%) of the 47 lower-middle income, 15 (28%) of the 53 upper-middle-income and 7 (12%) of the 59 high-income. Of the 140 implementations, 63 (45%) could be categorized as needs assessments, 38 (27%) as endorsements by stakeholders, 20 (14%) as incorporations into policy and 19 (14%) as educational interventions. CONCLUSION: Although WHO's trauma care guidelines have been widely implemented, no evidence was identified of their implementation in 143 countries. More serial needs assessments for the ongoing monitoring of capacity for trauma care in health systems and more incorporation of the guidelines into both the formal education of health-care providers and health policy are needed.

RESUMEN

Individuals with sickle cell anemia (SCA) have increased susceptibility to infections, secondary to impairment of immune function. Besides the described dysfunction in innate immunity, including impaired opsonization and phagocytosis of bacteria, evidence of dysfunction of T and B lymphocytes in SCA has also been reported. This includes reduction in the proportion of circulating CD4+ and CD8+ T cells, reduction of CD4+ helper: CD8+ suppressor T cell ratio, aberrant activation and dysfunction of regulatory T cells (Treg ), skewing of CD4+ T cells towards Th2 response and loss of IgM-secreting CD27 + IgM(high) IgD(low) memory B cells. These changes occur on the background of immune activation characterized by predominance of memory CD4+ T cell phenotypes, increased Th17 signaling and elevated levels of C-reactive protein and pro-inflammatory cytokines IL-6 and TNF-α, which may affect the immunogenicity and protective efficacy of vaccines available to prevent infections in SCA. Thus, in order to optimize the use of vaccines in SCA, a thorough understanding of T and B lymphocyte functions and vaccine reactivity among individuals with SCA is needed. Studies should be encouraged of different SCA populations, including sub-Saharan Africa where the burden of SCA is highest. This article summarizes our current understanding of lymphocyte biology in SCA, and highlights areas that warrant future research. Am. J. Hematol. 91:938-946, 2016. © 2016 Wiley Periodicals, Inc.

RESUMEN

OBJECTIVE: To estimate the global and national burden of emergency conditions, and compare them to emergency care usage rates. METHODS: We coded all 291 Global Burden of Disease 2010 conditions into three categories to estimate emergency burden: conditions that, if not addressed within hours to days of onset, commonly lead to serious disability or death; conditions with common acute decompensations that lead to serious disability or death; and non-emergencies. Emergency care usage rates were obtained from a systematic literature review on emergency care facilities in low-income and middle-income countries (LMICs), supplemented by national health system reports. FINDINGS: All 15 leading causes of death and disability-adjusted life years (DALYs) globally were conditions with potential emergent manifestations. We identified 41 facility-based reports in 23 countries, 12 of which were in LMICs; data for 17 additional countries were obtained from national or regional reports on emergency usage. Burden of emergency conditions was the highest in low-income countries, with median DALYs of 47 728 per 100 000 population (IQR 45 253-50 085) in low-income, 25 186 (IQR 21 982-40 480) in middle-income and 15 691 (IQR 14 649-16 382) in high-income countries. Patterns were similar using deaths to measure burden and excluding acute decompensations from the definition of emergency conditions. Conversely, emergency usage rates were the lowest in low-income countries, with median 8 visits per 1000 population (IQR 6-10), 78 (IQR 25-197) in middle-income and 264 (IQR 177-341) in high-income countries. CONCLUSIONS: Despite higher burden of emergency conditions, emergency usage rates are substantially lower in LMICs, likely due to limited access to emergency care.

RESUMEN

OBJECTIVES: To evaluate the test characteristics of clinical gestalt for detecting the presence and severity of anaemia in emergency department patients at a tertiary referral hospital in Tanzania. METHODS: This prospective study enrolled a convenience sample of emergency department patients who had a complete blood count ordered by the treating physician in the course of their clinical care. Physicians recorded their impression of the presence and severity of anaemia before viewing the laboratory results. To assess interobserver agreement, a second physician provided their blinded gestalt impression of the patient's haemoglobin level. RESULTS: We enrolled 216 patients and complete data were available for 210 patients (97%), 59% male, median age 30 years. The range of measured haemoglobin values was 1.5-15.4 g/dL. The physicians rated anaemia mild or absent in 74 (35%), moderate in 72 (34%) and severe in 64 patients (30%). These estimates were significantly concordant with the laboratory haemoglobin measurements (Kendall's τ b=0.63, 95% CI 0.57 to 0.69, p<0.0001). The test characteristics of physician gestalt estimates for severe anaemia were: sensitivity 64% (95% CI 53% to 74%), specificity 91% (95% CI 85% to 96%), positive likelihood ratio of 7.4 (95% CI 4.2 to 13.3) and negative likelihood ratio of 0.40 (0.3 to 0.5). The weighted Cohen's κ for interobserver agreement between physicians on the gestalt estimate of the degree of anaemia was 0.87 (95% CI 0.76 to 0.98). CONCLUSION: Physicians' estimates of the severity of anaemia were significantly concordant with laboratory haemoglobin measurements. Sensitivity of the gestalt estimate for severe anaemia was moderate. Interobserver agreement was 'almost perfect'.

RESUMEN

A major barrier to successful integration of acute care into health systems is the lack of consensus on the essential components of emergency care within resource-limited environments. The 2013 African Federation of Emergency Medicine Consensus Conference was convened to address the growing need for practical solutions to further implementation of emergency care in sub-Saharan Africa. Over 40 participants from 15 countries participated in the working group that focused on emergency care delivery at health facilities. Using the well-established approach developed in the WHO's Monitoring Emergency Obstetric Care, the workgroup identified the essential services delivered-signal functions-associated with each emergency care sentinel condition. Levels of emergency care were assigned based on the expected capacity of the facility to perform signal functions, and the necessary human, equipment and infrastructure resources identified. These consensus-based recommendations provide the foundation for objective facility capacity assessment in developing emergency health systems that can bolster strategic planning as well as facilitate monitoring and evaluation of service delivery.

RESUMEN

OBJECTIVE: To conduct a systematic review of emergency care in low- and middle-income countries (LMICs). METHODS: We searched PubMed, CINAHL and World Health Organization (WHO) databases for reports describing facility-based emergency care and obtained unpublished data from a network of clinicians and researchers. We screened articles for inclusion based on their titles and abstracts in English or French. We extracted data on patient outcomes and demographics as well as facility and provider characteristics. Analyses were restricted to reports published from 1990 onwards. FINDINGS: We identified 195 reports concerning 192 facilities in 59 countries. Most were academically-affiliated hospitals in urban areas. The median mortality within emergency departments was 1.8% (interquartile range, IQR: 0.2-5.1%). Mortality was relatively high in paediatric facilities (median: 4.8%; IQR: 2.3-8.4%) and in sub-Saharan Africa (median: 3.4%; IQR: 0.5-6.3%). The median number of patients was 30 000 per year (IQR: 10 296-60 000), most of whom were young (median age: 35 years; IQR: 6.9-41.0) and male (median: 55.7%; IQR: 50.0-59.2%). Most facilities were staffed either by physicians-in-training or by physicians whose level of training was unspecified. Very few of these providers had specialist training in emergency care. CONCLUSION: Available data on emergency care in LMICs indicate high patient loads and mortality, particularly in sub-Saharan Africa, where a substantial proportion of all deaths may occur in emergency departments. The combination of high volume and the urgency of treatment make emergency care an important area of focus for interventions aimed at reducing mortality in these settings.
