Assessing the indirect effects of COVID-19 on healthcare delivery, utilization and health outcomes: a scoping review.

BACKGROUND: The COVID-19 pandemic and global efforts to contain its spread, such as stay-at-home orders and transportation shutdowns, have created new barriers to accessing healthcare, resulting in changes in service delivery and utilization globally. The purpose of this study is to provide an overview of the literature published thus far on the indirect health effects of COVID-19 and to explore the data sources and methodologies being used to assess indirect health effects. METHODS: A scoping review of peer-reviewed literature using three search engines was performed. RESULTS: One hundred and seventy studies were included in the final analysis. Nearly half (46.5%) of included studies focused on cardiovascular health outcomes. The main methodologies used were observational analytic and surveys. Data were drawn from individual health facilities, multicentre networks, regional registries, and national health information systems. Most studies were conducted in high-income countries with only 35.4% of studies representing low- and middle-income countries (LMICs). CONCLUSION: Healthcare utilization for non-COVID-19 conditions has decreased almost universally, across both high- and lower-income countries. The pandemic's impact on non-COVID-19 health outcomes, particularly for chronic diseases, may take years to fully manifest and should be a topic of ongoing study. Future research should be tied to system improvement and the promotion of health equity, with researchers identifying potentially actionable findings for national, regional and local health leadership. Public health professionals must also seek to address the disparity in published data from LMICs as compared with high-income countries.

Public Health Rationale for Investments in Emergency Medicine in Developing Countries - Ghana as a Case Study.

BACKGROUND: Ghana is a developing country that has strategically invested in expanding emergency care services as a means of improving national health outcomes. OBJECTIVES: Here we present Ghana as a case study for investing in emergency care to achieve public health benefits that fuel for national development. DISCUSSION: Ghana's health leadership has affirmed emergency care as a necessary adjunct to its preexisting primary health care model. Historically, developing countries prioritize primary care efforts and outpatient clinic-based health care models. Ghana has added emergency medicine infrastructure to its health care system in an effort to address the ongoing shift in disease epidemiology as the population urbanizes, mobilizes, and ages. Ghana's investments include prehospital care, personnel training, health care resource provision, communication improvements, transportation services, and new health facilities. This is in addition to re-educating frontline health care providers and developing infrastructure for specialist training. Change was fueled by public support, partnerships between international organizations and domestic stakeholders, and several individual champions. CONCLUSION: Emergency medicine as a horizontal component of low- to middle-income countries' health systems may fuel national health and economic development. Ghana's experience may serve as a model.

Development and Implementation of a Training-of-Trainers Program for Continuous Positive Airway Pressure in Neonatal and Pediatric Patients in Five Low- and Middle-Income Countries.

We describe a pragmatic training-of-trainers program for the use of continuous positive airway pressure (CPAP) for neonatal and pediatric patients. The program is designed for medical professionals working in low- and middle-income countries and involves 2 days of in-class training followed by 1 day of in-service training. The program was created after training in Cambodia, Ghana, Honduras, Kenya and Rwanda and addresses the issues of resource availability, cultural context and local buy-in and partnership in low- and middle-income countries. We hope others will use the training program to increase knowledge and use of CPAP with the ultimate goal of improving neonatal and pediatric survival globally.

Aftermath of a clinical trial: evaluating the sustainability of a medical device intervention in Ghana.

A randomized controlled trial recently demonstrated that continuous positive airway pressure (CPAP) effectively decreases respiratory rate in children presenting to Ghanaian district hospitals with respiratory distress. A follow-up study 16 months later evaluated the extent to which the skills and equipment necessary for CPAP use have been maintained. Seven of eight CPAP machines were functional, but five of eight oxygen concentrators and three of four electric generators were non-functional. Nurses trained by US study personnel (first-generation) and nurses trained by Ghanaian nurses after the study (second-generation) were evaluated on CPAP knowledge and skills. Twenty-eight nurses participated in the study, 9 first-generation and 19 second-generation. First-generation trainees scored significantly higher than second-generation trainees on both skills and knowledge assessments (p = 0.003). Appropriate technical support and training must be ensured to address equipment maintenance. Protocolization of the training program, in conjunction with skills and knowledge assessment, may improve acquisition and retention among second- and future-generation trainees.

A randomized clinical trial evaluating nasal continuous positive airway pressure for acute respiratory distress in a developing country.

OBJECTIVE: Invasive mechanical ventilation is often not an option for children with acute respiratory infections in developing countries. An alternative is continuous positive airway pressure (CPAP). The authors evaluated the effectiveness of CPAP in children presenting with acute respiratory distress in a developing country. STUDY DESIGN: A randomized, controlled trial was conducted in 4 rural hospitals in Ghana. Children, 3 months to 5 years of age, presenting with tachypnea and intercostal or subcostal retractions or nasal flaring were randomly assigned to receive CPAP immediately or 1 hour after presentation. CPAP was applied by locally trained nurses. The primary outcome measure was change in respiratory rate at 1 hour. RESULTS: The study was stopped after the enrollment of 70 subjects because of a predetermined stop value of P < .001. Mean respiratory rate of children who received immediate CPAP fell by 16 breaths/min (95% CI 10-21) in the first hour compared with no change in children who had CPAP delayed by 1 hour (95% CI -2 to +5). Thirty-five of the patients had a positive malaria blood smear. There were 3 deaths as a result of severe malaria. No major complications of CPAP use were noted. CONCLUSIONS: CPAP decreases respiratory rate in children with respiratory distress compared with children not receiving CPAP. The technology was successfully used by local nurses. No complications were associated with its use. CPAP is a relatively low-cost, low-technology that is a safe method to decrease respiratory rate in children with nonspecific respiratory distress.

Head Injury Prevalence in a Population of Injured Patients Seeking Care in Ghana, West Africa.

Background/Significance: Much of the literature on head injury (HI) prevalence comes from high-income countries (HICs), despite the disproportionate burden of injuries in low to middle-income countries (LMICs). This study evaluated the HI prevalence in the Kintampo Injury Registry, a collaborative effort between Kintampo Health Research Centre (KHRC) in Ghana and the sidHARTe Program at Columbia University Mailman School of Public Health. In our first aim, we characterize the HI prevalence in the registry. In aim 2, we examine if there are any sex (male/female) differences in head injury outcomes in these populations for points of potential intervention. Methods: Secondary analysis of data from the Kintampo Injury Registry which had 7,148 registered patients collected during January 2013 to January 2015. The definition of a case was adopted to ensure consistency with the International Statistical Classification of Diseases and Related Health Problems, revision 10 (ICD-10). A 3-page questionnaire was used to collect data from injured patients to include in the registry. The questions were designed to be consistent with the World Health Organization (WHO) guidelines on injury surveillance and were adapted from the questionnaire used in a pilot, multi-country injury study undertaken in other parts of Africa. The questionnaire collected information on the anatomic site of injury (e.g., head), mechanism of injury (e.g., road traffic injuries, interpersonal injuries (including domestic violence), falls, drowning, etc.), severity and circumstances of the injury, as well as precipitating factors, such as alcohol and drug use. The questionnaire consisted mainly of close-ended questions and was designed for efficient data entry. For the secondary data analyses for this manuscript, we only included those with "1st visit following injury" and excluded all transfers and follow-up visits (n = 834). We then dichotomized the remaining 6,314 patients to head injured and non-head injured patients based on responses to the variable "Nature of injury =Head Injury". We used chi-square and Fisher's exact tests with p < 0.05 as cut-off for statistical significance. Logistic regression estimates were used for effect estimates. Results: Of the 6,314 patients, there were 208 (3.3%) head-injured patients and 6,106 (96.7%) patients without head injury. Head-injured patients tended to be older (Mean age: 28.9 +/-13.7; vs. 26.1 +/- 15.8; p = 0.004). Seven in 10 head injured patients sustained their injuries via transport/road traffic accidents, and head-injured patients had 13 times the odds of mortality compared with those without head injuries (OR: 13.3; 95% CI: 8.05, 22.0; p < 0.0001) even though over half of them had mild or moderate injury severity scores (p < 0.001). Evaluation of sex differences amongst the head-injured showed that in age-adjusted logistic regression models, males had 1.4 times greater odds of being head injured (OR: 1.4; 95% CI: 1.04, 2.00; p = 0.03) and over twice the risk of mortality (OR: 2.7; 95% CI: 0.74, 10.00; p = 0.13) compared to females. Conclusion: In these analyses, HI was associated with a higher risk of mortality, particularly amongst injured males; most of whom were injured in transport/road-traffic-related accidents. This study provides an impetus for shaping policy around head injury prevention in LMICs like Ghana.

Authorship representation in global emergency medicine: a bibliometric analysis from 2016 to 2020.

INTRODUCTION: High-income country (HIC) authors are disproportionately represented in authorship bylines compared with those affiliated with low and middle-income countries (LMICs) in global health research. An assessment of authorship representation in the global emergency medicine (GEM) literature is lacking but may inform equitable academic collaborations in this relatively new field. METHODS: We conducted a bibliometric analysis of original research articles reporting studies conducted in LMICs from the annual GEM Literature Review from 2016 to 2020. Data extracted included study topic, journal, study country(s) and region, country income classification, author order, country(s) of authors' affiliations and funding sources. We compared the proportion of authors affiliated with each income bracket using Χ2 analysis. We conducted logistic regression to identify factors associated with first or last authorship affiliated with the study country. RESULTS: There were 14 113 authors in 1751 articles. Nearly half (45.5%) of the articles reported work conducted in lower middle-income countries (MICs), 23.6% in upper MICs, 22.5% in low-income countries (LICs). Authors affiliated with HICs were most represented (40.7%); 26.4% were affiliated with lower MICs, 17.4% with upper MICs, 10.3% with LICs and 5.1% with mixed affiliations. Among single-country studies, those without any local authors (8.7%) were most common among those conducted in LICs (14.4%). Only 31.0% of first authors and 21.3% of last authors were affiliated with LIC study countries. Studies in upper MICs (adjusted OR (aOR) 3.6, 95% CI 2.46 to 5.26) and those funded by the study country (aOR 2.94, 95% CI 2.05 to 4.20) had greater odds of having a local first author. CONCLUSIONS: There were significant disparities in authorship representation. Authors affiliated with HICs more commonly occupied the most prominent authorship positions. Recognising and addressing power imbalances in international, collaborative emergency medicine (EM) research is warranted. Innovative methods are needed to increase funding opportunities and other support for EM researchers in LMICs, particularly in LICs.

COVID-19 Pandemic Prompts a Paradigm Shift in Global Emergency Medicine: Multidirectional Education and Remote Collaboration.

To date, the practice of global emergency medicine (GEM) has involved being "on the ground" supporting in-country training of local learners, conducting research, and providing clinical care. This face-to-face interaction has been understood as critically important for developing partnerships and building trust. The COVID-19 pandemic has brought significant uncertainty worldwide, including international travel restrictions of indeterminate permanence. Following the 2020 Society for Academic Emergency Medicine meeting, the Global Emergency Medicine Academy (GEMA) sought to enhance collective understanding of best practices in GEM training with a focus on multidirectional education and remote collaboration in the setting of COVID-19. GEMA members led an initiative to outline thematic areas deemed most pertinent to the continued implementation of impactful GEM programming within the physical and technologic confines of a pandemic. Eighteen GEM practitioners were divided into four workgroups to focus on the following themes: advances in technology, valuation, climate impacts, skill translation, research/scholastic projects, and future challenges. Several opportunities were identified: broadened availability of technology such as video conferencing, Internet, and smartphones; online learning; reduced costs of cloud storage and printing; reduced carbon footprint; and strengthened local leadership. Skills and knowledge bases of GEM practitioners, including practicing in resource-poor settings and allocation of scarce resources, are translatable domestically. The COVID-19 pandemic has accelerated a paradigm shift in the practice of GEM, identifying a previously underrecognized potential to both strengthen partnerships and increase accessibility. This time of change has provided an opportunity to enhance multidirectional education and remote collaboration to improve global health equity.

Respiratory Pathogens in Children 1 Month to 5 Years of Age Presenting With Undifferentiated Acute Respiratory Distress in 2 District-Level Hospitals in Ghana.

Ghanaian children (2176) aged <5 years who presented with undifferentiated acute respiratory distress were tested for respiratory pathogens using a BioFire FilmArray polymerase chain reaction assay. Rhinovirus and/or enterovirus was detected in 36% of the assays, respiratory syncytial virus in 11%, and parainfluenza in 7%. Respiratory syncytial virus and metapneumovirus were detected more frequently in the rainy season than in the dry season.

Impact of emergency medicine training implementation on mortality outcomes in Kigali, Rwanda: An interrupted time-series study.

INTRODUCTION: Although emergency medicine (EM) training programmes have begun to be introduced in low- and middle-income countries (LMICs), minimal data exist on their effects on patient-centered outcomes in such settings. This study evaluated the impact of EM training and associated systems implementation on mortality among patients treated at the University Teaching Hospital-Kigali (UTH-K). METHODS: At UTH-K an EM post-graduate diploma programme was initiated in October 2013, followed by a residency-training programme in August 2015. Prior to October 2013, care was provided exclusively by general practice physicians (GPs); subsequently, care has been provided through mutually exclusive shifts allocated between GPs and EM trainees. Patients seeking Emergency Centre (EC) care during November 2012-October 2013 (pre-training) and August 2015-July 2016 (post-training) were eligible for inclusion. Data were abstracted from a random sample of records using a structured protocol. The primary outcomes were EC and overall hospital mortality. Mortality prevalence and risk differences (RD) were compared pre- and post-training. Magnitudes of effects were quantified using regression models to yield adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: From 43,213 encounters, 3609 cases were assessed. The median age was 32 years with a male predominance (60.7%). Pre-training EC mortality was 6.3% (95% CI 5.3-7.5%), while post-training EC mortality was 1.2% (95% CI 0.7-1.8%), constituting a significant decrease in adjusted analysis (aOR = 0.07, 95% CI 0.03-0.17; p < 0.001). Pre-training overall hospital mortality was 12.2% (95% CI 10.9-13.8%). Post-training overall hospital mortality was 8.2% (95% CI 6.9-9.6%), resulting in a 43% reduction in mortality likelihood (aOR = 0.57, 95% CI 0.36-0.94; p = 0.016). DISCUSSION: In the studied population, EM training and systems implementation was associated with significant mortality reductions demonstrating the potential patient-centered benefits of EM development in resource-limited settings.

Advancing research on emergency care systems in low-income and middle-income countries: ensuring high-quality care delivery systems.

Emergency care systems (ECS) address a wide range of acute conditions, including emergent conditions from communicable diseases, non-communicable diseases, pregnancy and injury. Together, ECS represent an area of great potential for reducing morbidity and mortality in low-income and middle-income countries (LMICs). It is estimated that up to 54% of annual deaths in LMICs could be addressed by improved prehospital and facility-based emergency care. Research is needed to identify strategies for enhancing ECS to optimise prevention and treatment of conditions presenting in this context, yet significant gaps persist in defining critical research questions for ECS studies in LMICs. The Collaborative on Enhancing Emergency Care Research in LMICs seeks to promote research that improves immediate and long-term outcomes for clients and populations with emergent conditions. The objective of this paper is to describe systems approaches and research strategies for ECS in LMICs, elucidate priority research questions and methodology, and present a selection of studies addressing the operational, implementation, policy and health systems domains of health systems research as an approach to studying ECS. Finally, we briefly discuss limitations and the next steps in developing ECS-oriented interventions and research.

Health Professional Training and Capacity Strengthening Through International Academic Partnerships: The First Five Years of the Human Resources for Health Program in Rwanda.

BACKGROUND: The Rwanda Human Resources for Health Program (HRH Program) is a 7-year (2012-2019) health professional training initiative led by the Government of Rwanda with the goals of training a large, diverse, and competent health workforce and strengthening the capacity of academic institutions in Rwanda. METHODS: The data for this organizational case study was collected through official reports from the Rwanda Ministry of Health (MoH) and 22 participating US academic institutions, databases from the MoH and the College of Medicine and Health Sciences (CMHS) in Rwanda, and surveys completed by the co-authors. RESULTS: In the first 5 years of the HRH Program, a consortium of US academic institutions has deployed an average of 99 visiting faculty per year to support 22 training programs, which are on track to graduate almost 4600 students by 2019. The HRH Program has also built capacity within the CMHS by promoting the recruitment of Rwandan faculty and the establishment of additional partnerships and collaborations with the US academic institutions. CONCLUSION: The milestones achieved by the HRH Program have been substantial although some challenges persist. These challenges include adequately supporting the visiting faculty; pairing them with Rwandan faculty (twinning); ensuring strong communication and coordination among stakeholders; addressing mismatches in priorities between donors and implementers; the execution of a sustainability strategy; and the decision by one of the donors not to renew funding beyond March 2017. Over the next 2 academic years, it is critical for the sustainability of the 22 training programs supported by the HRH Program that the health-related Schools at the CMHS significantly scale up recruitment of new Rwandan faculty. The HRH Program can serve as a model for other training initiatives implemented in countries affected by a severe shortage of health professionals.

Continuous positive airway pressure for children with undifferentiated respiratory distress in Ghana: an open-label, cluster, crossover trial.

BACKGROUND: In low-income and middle-income countries, invasive mechanical ventilation is often not available for children at risk of death from respiratory failure. We aimed to determine if continuous positive airway pressure (CPAP), a form of non-invasive ventilation, decreases all-cause mortality in children with undifferentiated respiratory distress in Ghana. METHODS: This open-label, cluster, crossover trial was done in two Ghanaian non-tertiary hospitals where invasive mechanical ventilation is not routinely available. Eligible participants were children aged from 1 month to 5 years with a respiratory rate of more than 50 breaths per min in children 1-12 months old, or more than 40 breaths per min in children older than 12 months, and use of accessory muscles or nasal flaring. CPAP machines were allocated to one hospital during each study block, while the other hospital served as the control site. The initial intervention site was randomly chosen using a coin toss. 5 cm of water pressure was delivered via CPAP nasal prongs. The primary outcome measure was all-cause mortality rate at 2 weeks after enrolment in patients for whom data were available after 2 weeks. We also did post-hoc regression analysis and subgroup analysis of children by malaria status, oxygen saturation, and age. This study is registered with ClinicalTrials.gov, number NCT01839474. FINDINGS: Between Jan 20, 2014, and Dec 5, 2015, 2200 children were enrolled: 1025 at the intervention site and 1175 at the control site. Final analysis included 1021 patients in the CPAP group and 1160 patients in the control group. 2 weeks after enrolment, 26 (3%) of 1021 patients in the CPAP group, and 44 (4%) of 1160 patients in the control group, had died (relative risk [RR] of mortality 0·67, 95% CI 0·42-1·08; p=0·11). In children younger than 1 year, all-cause mortality was ten (3%) of 374 patients in the CPAP group, and 24 (7%) of 359 patients in the control group (RR 0·40, 0·19-0·82; p=0·01). After adjustment for study site, time, and clinically important variables, the odds ratio for 2-week mortality in the CPAP group versus the control group was 0·4 in children aged up to 6 months, 0·5 for children aged 12 months, 0·7 for children aged 24 months, and 1·0 for those aged 36 months. 28 patients (3%) in the CPAP group and 24 patients (2%) in the control group had CPAP-related adverse events, such as vomiting, aspiration, and nasal, skin, or eye trauma. No serious adverse events were observed. INTERPRETATION: In the unadjusted analysis the use of CPAP did not decrease all-cause 2-week mortality in children 1 month to 5 years of age with undifferentiated respiratory distress. After adjustment for study site, time, and clinically important variables, 2-week mortality in the CPAP group versus the control group was significantly decreased in children 1 year of age and younger. CPAP is safe and improves respiratory rate in a non-tertiary setting in a lower-middle-income country. FUNDING: General Electric Foundation.

A research agenda for acute care services delivery in low- and middle-income countries.

Delivery of acute care services at every level of the health system is essential to ensure appropriate evaluation and management of emergent illness and injury in low- and middle-income countries (LMICs). The health services breakout group at the 2013 Academic Emergency Medicine consensus conference developed recommendations for a research agenda along the following themes: infrastructure, implementation, and sustainable provision of acute care services. Based on these recommendations, a set of priorities was created to promote and guide future research on acute care services.
