Critical care delivery across health care systems in low-income and low-middle-income country settings: A systematic review.

Background: Prior research has demonstrated that low- and low-middle-income countries (LLMICs) bear a higher burden of critical illness and have a higher rate of mortality from critical illness than high-income countries (HICs). There is a pressing need for improved critical care delivery in LLMICs to reduce this inequity. This systematic review aimed to characterise the range of critical care interventions and services delivered within LLMIC health care systems as reported in the literature. Methods: A search strategy using terms related to critical care in LLMICs was implemented in multiple databases. We included English language articles with human subjects describing at least one critical care intervention or service in an LLMIC setting published between 1 January 2008 and 1 January 2020. Results: A total of 1620 studies met the inclusion criteria. Among the included studies, 45% of studies reported on pediatric patients, 43% on adults, 23% on infants, 8.9% on geriatric patients and 4.2% on maternal patients. Most of the care described (94%) was delivered in-hospital, with the remainder (6.2%) taking place in out-of-hospital care settings. Overall, 49% of critical care described was delivered outside of a designated intensive care unit. Specialist physicians delivered critical care in 60% of the included studies. Additional critical care was delivered by general physicians (40%), as well as specialist physician trainees (22%), pharmacists (16%), advanced nursing or midlevel practitioners (8.9%), ambulance providers (3.3%) and respiratory therapists (3.1%). Conclusions: This review represents a comprehensive synthesis of critical care delivery in LLMIC settings. Approximately 50% of critical care interventions and services were delivered outside of a designated intensive care unit. Specialist physicians were the most common health care professionals involved in care delivery in the included studies, however generalist physicians were commonly reported to provide critical care interventions and services. This study additionally characterised the quality of the published evidence guiding critical care practice in LLMICs, demonstrating a paucity of interventional and cost-effectiveness studies. Future research is needed to understand better how to optimise critical care interventions, services, care delivery and costs in these settings. Registration: PROSPERO CRD42019146802.

Designing and developing a digital equity dashboard for the emergency department.

Disparities in diagnosis, treatment, and health outcomes of racial minorities are well documented in the emergency department (ED). Although EDs may provide broad departmental feedback on clinical metrics, lack of up-to-date monitoring and data availability present significant challenges to identifying and addressing patterns of inequitable care. To address this issue, we developed an online "Equity Dashboard," incorporating data that is updated daily from our electronic medical record to highlight demographic, clinical, and operational variables, stratified by age, race, ethnicity, and language, and sexual orientation, gender identity. Through an iterative design thinking process, we created data visualizations for an interactive interface that tells a story about the ED patient's experience and enables any staff to explore up-to-date trends in patient care. To assess and improve usability of the dashboard, we conducted a survey of end-users using custom questions, as well as the System Usability Scale and Net Promoter Score, both of which are validated health technology use instruments. The Equity Dashboard is of particular use for quality improvement initiatives, as it reflects common departmental challenges including delays in clinician events, inpatient boarding, and throughput metrics. This digital tool further helps demonstrate how these operational factors differentially affect our diverse patient population. The dashboard ultimately enables the ED team to measure current performance, to identify our vulnerabilities, and to design targeted interventions to address disparities in clinical care.

Implementation and outcomes of a comprehensive emergency care curriculum at a low-resource referral hospital in Liberia: A novel approach to application of the WHO Basic Emergency Care toolkit.

BACKGROUND: Emergency care is vital in low- and middle-income countries (LMICs) but many frontline healthcare workers in low-resource settings have no formal training in emergency care. To address this gap, the World Health Organization (WHO) developed Basic Emergency Care (BEC): Approach to the acutely ill and injured, a multi-day, open-source course for healthcare workers in low-resource settings. Building on the BEC foundation, this study uses an implementation science (IS) lens to develop, implement, and evaluate a comprehensive emergency care curriculum in a single emergency facility in Liberia. METHODS: A six-month emergency care curriculum consisting of BEC content, standardized WHO clinical documentation forms, African Federation of Emergency Medicine (AFEM) didactics, and clinical mentorship by visiting emergency medicine (EM) faculty was designed and implemented using IS frameworks at Redemption Hospital, a low-resource public referral hospital in Monrovia, the capital of Liberia. Healthcare worker performance on validated knowledge-based exams during pre- and post-intervention testing, post-course surveys, and patient outcomes were used to evaluate the program. RESULTS: Nine visiting EM physicians provided 1400 hours of clinical mentorship and 560 hours of didactic training to fifty-six Redemption Hospital staff over six-months. Median test scores improved 20.0% (p<0.001) among the forty-three healthcare workers who took both the pre- and post-intervention tests. Participants reported increased confidence in caring for medical and trauma patients and comfort performing emergency care tasks on post-course surveys. Emergency unit (EU)/Isolation unit (IU) mortality decreased during the six-month implementation period, albeit non-significantly. Course satisfaction was high across multiple domains. DISCUSSION: This study builds on prior research supporting WHO efforts to improve emergency care globally. BEC implementation over a six-month timeframe using IS principles is an effective alternative strategy for facilities in resource-constrained environments wishing to strengthen emergency care delivery.

Emergency department antimicrobial use in a low-resource setting: results from a retrospective observational study at a referral hospital in Liberia.

OBJECTIVE: Data on antimicrobial use in low-income and middle-income countries (LMICs) remain limited. In Liberia, the absence of local data impedes surveillance and may lead to suboptimal treatment, injudicious use and resistance against antimicrobials. This study aims to examine antimicrobial prescribing patterns for patients in the emergency department (ED) of a large Liberian public hospital. Secondarily, this prescribing was compared with WHO prescribing indicators. DESIGN: Retrospective observational study. SETTING: An adult ED of a large public hospital in Monrovia, Liberia. PARTICIPANTS: A total of 1082 adult patients (>18 years of age) were recorded in the ED, from 1 January to 30 June 2019. MAIN OUTCOME MEASURES: Number, type and name of antimicrobials ordered per patient were presented as number and percentages, with comparison to known WHO prescribing indicators. Pearson χ2 tests were used to assess patient variables and trends in medication use. RESULTS: Of the total patients, 44.0% (n=476) were female and the mean age was 40.2 years (SD=17.4). An average of 2.78 (SD=2.02) medicines were prescribed per patient encounter. At least one antimicrobial was ordered for 64.5% encounters (n=713) and two or more antimicrobials for 35.7% (n=386). All antimicrobial orders in our sample used the generic name. Ceftriaxone, metronidazole and ampicillin were the most common and accounted for 61.2% (n=743) of antimicrobial prescriptions. The majority (99.9%, n=1211) of antimicrobials prescribed were from the WHO Essential Drugs List. CONCLUSION: This study is one of the first on ED-specific antimicrobial use in LMICs. We revealed a high rate of antimicrobial prescription, regardless of patient demographic or diagnosis. While empiric antimicrobial use is justified in certain acute clinical scenarios, the high rate from this setting warrants further investigation. The results of this study underscore the importance of ED surveillance to develop targeted antimicrobial stewardship interventions and improve patient care.

Critical care service delivery across healthcare systems in low-income and low-middle-income countries: protocol for a systematic review.

INTRODUCTION: Critical care in low-income and low-middle income countries (LLMICs) is an underdeveloped component of the healthcare system. Given the increasing growth in demand for critical care services in LLMICs, understanding the current capacity to provide critical care is imperative to inform policy on service expansion. Thus, our aim is to describe the provision of critical care in LLMICs with respect to patients, providers, location of care and services and interventions delivered. METHODS AND ANALYSIS: We will search PubMed/MEDLINE, Web of Science and EMBASE for full-text original research articles available in English describing critical care services that specify the location of service delivery and describe patients and interventions. We will restrict our review to populations from LLMICs (using 2016 World Bank classifications) and published from 1 January 2008 to 1 January 2020. Two-reviewer agreement will be required for both title/abstract and full text review stages, and rate of agreement will be calculated for each stage. We will extract data regarding the location of critical care service delivery, the training of the healthcare professionals providing services, and the illnesses treated according to classification by the WHO Universal Health Coverage Compendium. ETHICS AND DISSEMINATION: Reviewed and exempted by the Stanford University Office for Human Subjects Research and IRB on 20 May 2020. The results of this review will be disseminated through scholarly publication and presentation at regional and international conferences. This review is designed to inform broader WHO, International Federation for Emergency Medicine and partner efforts to strengthen critical care globally. PROSPERO REGISTRATION NUMBER: CRD42019146802.

Estimating children's weight in a Rwandan emergency centre.

INTRODUCTION: Most drugs, fluids and ventilator settings depend on the weight of a paediatric patient. However, knowledge of the weight is often unavailable as the urgency of the situation may impede measurement. The most common methods for paediatric weight estimation are based on height or age. This study aimed to compare the accuracy of various weight estimation methods and to derive a dedicated age-based tool within a Rwandan setting. METHODS: This was a retrospective study using age, weight and height data from randomly selected charts of Rwandan children, aged between one and ten years, who attended the paediatric emergency centre, Centre Hospitalier Universitaire de Kigali, Rwanda. Weights were estimated using four versions of the Broselow Tape and several age-based formulae. Linear regression was used to derive a new age-based weight estimation formula, the Rwanda Rule. Weight estimations were then compared with actual weight using Bland-Altman analysis, and the proportions of estimates within 10 and 20% of actual weight. RESULTS: There were 327 children included in the study. The derived Rwanda Rule was: weight (kg) = [1.7 × age (years)] + 8. This formula and the original Advanced Paediatric Life Support formula (weight = [2 × age] + 8) performed similarly. Both were better than other age-based formulae (69% of estimates within 20% of actual weight). All editions of the Broselow Tape performed better than age-based rules. The 1998 version performed best with 84.8% of estimates within 20% of actual weight. DISCUSSION: This study is the first to compare paediatric weight estimation methods in Rwanda. Locally, and until we have evidence from further research that other methods are superior, we would advise use of the 1998 Broselow Tape in children aged one to ten years old. Where the Broselow Tape is not available, the original Advanced Paediatric Life Support formula should be used.

Gender-based analysis of factors affecting junior medical students' career selection: addressing the shortage of surgical workforce in Rwanda.

BACKGROUND: There is a strong need for expanding surgical workforce in low- and middle-income countries. However, the number of medical students selecting surgical careers is not sufficient to meet this need. In Rwanda, there is an additional gender gap in speciality selection. Our study aims to understand the early variables involved in junior medical students' preference of specialisation with a focus on gender disparities. METHODS: We performed a cross-sectional survey of medical students during their clinical rotation years at the University of Rwanda. Demographics, specialisation preference, and factors involved in that preference were obtained using questionnaires and analysed using descriptive statistics and odds ratios. RESULTS: One hundred eighty-one respondents participated in the study (49.2% response rate) with a female-to-male ratio of 1 to 2.5. Surgery was the preferred speciality for 46.9% of male participants, and obstetrics/gynaecology for 29.4% of females. The main selection criteria for those who had already decided on surgery as a career included intellectual challenge (60.0%), interaction with residents (52.7%), and core clerkship experience (41.8%) for male participants and interaction with residents (57.1%), intellectual challenge (52.4%), and core clerkship experience (52.4%) for female participants. Females were more likely than males to join surgery based on perceived research opportunities (OR 2.7, p = 0.04). Male participants were more likely than their female participants to drop selection of surgery as a speciality when an adverse interaction with a resident was encountered (OR 0.26, p = 0.03). CONCLUSION: This study provides insight into factors that guide Rwandan junior medical students' speciality preference. Medical students are more likely to consider surgical careers when exposed to positive clerkship experiences that provide intellectual challenges, as well as focused mentorship that facilitates effective research opportunities. Ultimately, creating a comprehensive curriculum that supports students' preferences may help encourage their selection of surgical careers.

A qualitative study on perceptions of surgical careers in Rwanda: A gender-based approach.

Access to surgical care in low- and middle-income countries (LMICs) remains deficient without an adequate workforce. There is limited understanding of the gender gap in surgical trainees in LMICs. In Rwanda, females fill only one of 20 positions available. Understanding surgeons' experiences and perceptions of surgical careers may help facilitate support for females to contribute to the global surgical workforce. We performed qualitative analysis on perceptions of surgical careers through semi-structured interviews of all female surgeons (n = 6) and corresponding male surgeons (n = 6) who are training or have trained at University of Rwanda. Transcripts were analyzed with code structure formed through an integrated approach. Question categories formed the deductive framework, while theoretical saturation was reached through inductive grounded theory. Themes were organized within two key points of the career timeline. First, for developing interest in surgery, three main themes were identified: role models, patient case encounters, and exposure to surgery. Second, for selecting and sustaining surgical careers, four main themes emerged: social expectations about roles within the family, physical and mental challenges, professional and personal support, and finances. All female surgeons emphasized gender assumptions and surgical working culture as obstacles, with a corresponding strong sense of self-confidence and internal motivation that drew them to select and maintain careers in surgery. Family, time, and physical endurance were cited as persistent challenges for female participants. Our study reveals concepts for further exploration about gendered perceptions of surgical careers. Efforts to improve support for female surgical careers as a strategy for shaping surgical work culture and professional development in Rwanda should be considered. Such strategies may be beneficial for improving the global surgical workforce.

Improving Surgical Safety and Nontechnical Skills in Variable-Resource Contexts: A Novel Educational Curriculum.

OBJECTIVE: A substantial proportion of adverse intraoperative events are attributed to failures in nontechnical skills. To strengthen these skills and improve surgical safety, the Non-Technical Skills for Surgeons (NOTSS) taxonomy was developed as a common framework. The NOTSS taxonomy was adapted for low- and middle-income countries, where variable resources pose a significant challenge to safe surgery. The NOTSS for variable-resource contexts (VRC) curriculum was developed and implemented in Rwanda, with the aim of enhancing knowledge and attitudes about nontechnical skills and promoting surgical safety. DESIGN: The NOTSS-VRC curriculum was developed through a rigorous process of integrating contextually appropriate values. It was implemented as a 1-day training course for surgical and anesthesia postgraduate trainees. The curriculum comprises lectures, videos, and group discussions. A pretraining and posttraining questionnaire was administered to compare knowledge and attitudes regarding nontechnical skills, and their potential to improve surgical safety. SETTING: The setting of this study was in the tertiary teaching hospital of Kigali, Rwanda. PARTICIPANTS: Participants were residents of the University of Kigali. A total of 55 residents participated from general surgery (31.4%), obstetrics (25.5%), anesthesia (17.6%), and other surgical specialties (25.5%). RESULTS: In a paired analysis, understanding of NOTSS improved significantly (55.6% precourse, 80.9% postcourse, p<0.01). All residents reported that the course would improve their ability to provide safer patient care, and 97.4% believed developing nontechnical skills would improve patient outcomes. CONCLUSIONS: Nontechnical skills must be highlighted in surgical training in low- and middle-income countries. The NOTSS-VRC curriculum can be implemented without additional technology or significant financial cost. Its deliberate design for resource-constrained settings allows it to be used both as an educational course and a quality improvement strategy. Our research demonstrates it is feasible to improve knowledge and attitudes about NOTSS through a 1-day course, and represents a novel approach to improving global surgical safety.

Specialization in acute care surgery in low-income and middle-income countries.

Traumatic injuries represent the highest portion of surgical conditions worldwide, and the groups most vulnerable to these injuries are disproportionately in low-income and middle-income countries (LMICs). It is in this context that we recognize and propose an urgent opportunity for developing and strengthening the field of acute care surgery (ACS) in LMICs. In this article, we will briefly review the history and advantages of ACS as a specialty and recognize the unique opportunity and benefit it may have in LMICs.

Developing and implementing a global emergency medicine course: Lessons learned from Rwanda.

BACKGROUND: There is a growing demand by medical trainees for meaningful, short-term global emergency medicine (EM) experiences. EM programs in high-income countries (HICs) have forged opportunities for their trainees to access this experience in low-and middle-income countries (LMICs). However, few programs in LMICs have created and managed such courses. As more LMICs establish EM programs, these settings are ideal for developing courses beneficial for all participants. We describe our experience of creating and implementing a short-term global EM course in Rwanda. OBJECTIVES: The objectives of this study were to (1) provide EM trainees from HICs with an opportunity to observe global clinical practice and to learn from local experts, (2) provide EM trainees from an LMIC with an opportunity to share their expert knowledge and skills with HIC trainees, (3) create a sustainable model for a short-term global EM course in an LMIC context. METHODS: A global EM curriculum and course were developed in Rwanda, entitled EM in the Tropics Emergency Medicine in the Tropics (EMIT). The following topics were covered: EM systems development, public health, trauma/triage, pediatrics, disaster management, and tropical EM. A one-and two-week course program was created and implemented. RESULTS: EMIT participants rotated through pediatric and adult EDs, Intensive Care Unit, trauma surgery, internal medicine, emergency medical services, and ultrasound training. Activities included bedside teaching, case presentations, ultrasound practice, group lectures, simulation and skills workshops, and a rotation to a district hospital. A total of 11 participants attended: six for both weeks and five for 1 week. The course raised $5000 USD, which was dedicated in full to sponsoring local EM residents to attend international conferences. DISCUSSION: The EMIT course in Rwanda achieved its objectives of teaching and learning between all participants. Benefits of this in-person experience for both visiting and local participants are clear in clinical, intercultural, and professional ways. CONCLUSION: Our experience of developing and implementing EMIT in Rwanda demonstrates that EM programs in LMICs can provide short-term global EM courses that are not only beneficial to all participants, but also logistically and financially sustainable.

Volume-Based Enteral Nutrition Support Regimen Improves Caloric Delivery but May Not Affect Clinical Outcomes in Critically Ill Patients.

INTRODUCTION: Meeting enteral nutrition goals is an ongoing challenge in the intensive care unit (ICU). Most hospitals use rate-based (RB) protocols for nutrient delivery. Previous studies have found that volume-based (VB) protocols improve delivery of prescribed calories. However, these studies did not assess clinical outcomes. We hypothesize that a VB method will improve the delivery of prescribed calories and lead to improved clinical outcomes. METHODS: A before-and-after study was performed following implementation of a VB feeding protocol in an adult mixed medical-surgical ICU. Formal institutional review board approval was obtained. The effect of RB and VB protocols on percentage of goal calories received, ICU length of stay (LOS), hospital LOS, mortality, days on the ventilator, and rates of infection were investigated using the Kruskal-Wallis test of differences. Multivariate regression was used to identify independent predictors of outcome. Significance was defined as P < .05. RESULTS: A total of 77 patients were included (RB = 39, VB = 38). There were no differences in demographics between the 2 groups with the exception of the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, which was significantly higher in the VB group. VB patients received significantly more prescribed calories (74% vs 57%, P < .001). VB patients had significantly longer ICU LOS and duration of mechanical ventilation on univariate analysis. These differences did not persist after controlling for APACHE II score. CONCLUSION: VB enteral feeding allows for a significantly greater provision of prescribed calories but may not affect clinical outcomes. A larger sample size is needed for adequate power to corroborate these findings.

Upper Eyelid Coloboma Repair Using Accessory Preauricular Cartilage in a Patient With Goldenhar Syndrome: Technique Revisited.

We present an unusual case of upper eyelid coloboma repair in a patient with Goldenhar syndrome. We describe the use of a modified Cutler-Beard flap with concurrent inlay graft using cartilage from a preauricular appendage. This technique provides the benefits of autologous tissue, while minimizing donor site morbidity and reducing the risk of upper eyelid retraction.

Clinical Factors Associated with the Non-Operative Airway Management of Patients with Robin Sequence.

BACKGROUND: The indications for surgical airway management in patients with Robin sequence (RS) and severe airway obstruction have not been well defined. While certain patients with RS clearly require surgical airway intervention and other patients just as clearly can be managed with conservative measures alone, a significant proportion of patients with RS present with a more confusing and ambiguous clinical course. The purpose of this study was to describe the clinical features and objective findings of patients with RS whose airways were successfully managed without surgical intervention. METHODS: The authors retrospectively reviewed the medical charts of infants with RS evaluated for potential surgical airway management between 1994 and 2014. Patients who were successfully managed without surgical intervention were included. Patient demographics, nutritional and respiratory status, laboratory values, and polysomnography (PSG) findings were recorded. RESULTS: Thirty-two infants met the inclusion criteria. The average hospital stay was 16.8 days (range, 5-70 days). Oxygen desaturation (<70% by pulse oximetry) occurred in the majority of patients and was managed with temporary oxygen supplementation by nasal cannula (59%) or endotracheal intubation (31%). Seventy-five percent of patients required a temporary nasogastric tube for nutritional support, and a gastrostomy tube placed was placed in 9%. All patients continued to gain weight following the implementation of these conservative measures. PSG data (n=26) demonstrated mild to moderate obstruction, a mean apneahypopnea index (AHI) of 19.2±5.3 events/hour, and an oxygen saturation level <90% during only 4% of the total sleep time. CONCLUSIONS: Nonsurgical airway management was successful in patients who demonstrated consistent weight gain and mild to moderate obstruction on PSG, with a mean AHI of <20 events/hour.

An Unconventional Presentation of Branchio-Oculo-Facial Syndrome.

Branchio-oculo-facial syndrome (BOFS) is a rare disorder characterized by branchial or pharyngeal arch malformations, ocular findings, and craniofacial anomalies. Activating mutations in the enhancer-binding protein 2 alpha, TFAP2A, gene is responsible for the autosomal-dominant inheritance of BOFS. While documented patients of BOFS report wide variability in phenotype expressivity, patients typically demonstrate cervical or infra-auricular anomalies, diverse ocular malformations including microphthalmia and coloboma, and highly characteristic pseudo-cleft or palate defects. The authors present the case of an infant with an unconventional presentation of BOFS to highlight key distinguishing features of this disorder, and to emphasize the importance of a multidisciplinary approach in the diagnosis and management of these patients.

Frontal Encephalocele Associated With a Bilateral Tessier Number Three Cleft and Fraser Syndrome.

Oblique craniofacial clefts and encephaloceles are each rare conditions, and only a few instances of these findings in combination have been described. Each pathologic entity presents a unique reconstructive challenge. The authors report the case of a male infant who presented with a large right frontoencephalocele and bilateral Tessier number 3 clefts. A review of the pertinent literature, including specific considerations related to perioperative management and technical aspects of the surgical approach, is discussed.
