Exploring the factors motivating continued Lay First Responder participation in Uganda: a mixed-methods, 3-year follow-up

Emergency medical services impact evaluation approaches in low and middle-income countries

There is a strong need to critically consider the neocolonial context when discussing the impact evaluation of Eemergency Medical Services (EMS) systems in many low to middle-income countries. Many of these countries have faced exploitation and settler colonialism, and in today's world the aftermath of these political-economic unequal power dynamics persists through neocolonialism. "Solutions" to prehospital care and related donor-driven development sector aid programs are typically orchestrated by high-income countries in the Global North, many of whom directly benefited from centuries of colonizing the Global South. This perpetuates the financial and technocratic dependency of many low to middle-income countries. Traditional Global North-led impact assessment typically revolves around mortality outcomes. This is problematic because singularly tracking mortality can obscure the influence of important factors at play beyond the emergency response incident itself, such as morbidity and socioeconomic privilege. This is why process indicators such as response times and economic impacts on first responders and communities are crucial. Hence, instead of trying to develop a one-size-fits-all impact assessment criteria for all the diverse prehospital care system contexts across the world, it is important to focus on enabling bottom-up, community-led, and participatory approaches to finding context-tailored solutions. A key element of this should be the co-creation of the measures of success themselves with the community stakeholders. Such a decolonial holistic approach may then help put the spotlight on often neglected important measures, such as the inclusion of underprivileged minorities in emergency response and the level of protection against catastrophic health care expenditure built into EMS systems. In doing so, it can encourage a monitoring and evaluation shift from short-term mortality to long-term wellbeing, taking into account cultural contexts about what "wellbeing" entails. Furthermore, it is important to challenge the taken-for-granted notion that in low to middle-income countries, EMS systems are solely for trauma and medical emergencies. It is also important to consider (with the dialogue led by the local stakeholders) what sustainability would look like, and how resources accordingly should be allocated, in those regions in low to middle-income countries where there is political and economic volatility as a consequence of continuing neocolonial hegemony.

Leveraging transportation providers to deploy lay first responder (LFR) programs in three sub-Saharan African countries without formal emergency medical services: Evaluating longitudinal impact and cost-effectiveness

INTRODUCTION

In 2019, the World Health Assembly declared emergency care essential to achieve the 2030 Sustainable Development Goals. Few sub-Saharan African (SSA) countries have developed robust approaches to sustainably deliver emergency medical services (EMS) at scale, as high-income country models are financially impractical. Innovative reassessment of EMS delivery in resource-limited settings is necessary as timely emergency care access can substantially reduce mortality.

MATERIALS AND METHODS

We developed the Lay First Responder (LFR) program by training 1,291 pre-existing motorcycle taxi drivers, a predominant form of short-distance transport in sub-Saharan Africa, to provide trauma care and transport for road traffic injuries. Three pilot programs were launched in staggered fashion between 2016 and 2019 in West, Central, and East Africa and a 5.5 h curriculum was iteratively developed to train first responders. Longitudinal data on patient impact (patient demographics, injury characteristics, and treatment rendered), emergency care knowledge acquisition/retention, and social/financial effects of LFR training were collected and pooled across three sites for collective analysis. Novel cost-effectiveness ratios were calculated based on prospective cost data from each site. Previously projected aggregate disability-adjusted life years (DALYs) addressable by LFRs were used to inform cost-effectiveness ratios($USD cost per DALY averted). Cost-effectiveness ratios were then compared against African per capita gross domestic product (GDP), following WHOCHOICE guidelines, which state ratios less than GDP per capita are "very cost-effective."

RESULTS

In 2,171 total patient encounters across all three pilot sites, LFRs most frequently provided hemorrhage control in 61 % of patient encounters and patient transport by motorcycle in 98.5 %. Median pre-/post-test scores improved by 34.1 percentage points (39.5% vs.73.6 %, p < 0.0001) with significant knowledge retention at six months. 75 % of initial participants remain voluntarily involved 3 years post-course, reporting increased local stature and customer acquisition(income 32.0 % greater than non-trained counterparts). Locally sourced first-aid materials cost $6.54USD/participant. Cost-effectiveness analysis demonstrated cost per DALY averted=$51.65USD.

CONCLUSION

LFR training is highly cost-effective according to WHOCHOICE guidelines and expands emergency care access. The LFR program may be an alternative approach to formal ambulance-reliant EMS that are cost-prohibitive in resource-limited, sub-Saharan African settings. A novel social/financial mechanism appears to incentivize long-term voluntary LFR involvement, which may sustain programs in resource-limited settings.

Challenges, opportunities, and priorities for tier-1 emergency medical services (EMS) development in low- and middle-income countries: A modified Delphi-based consensus study among the global prehospital consortium

INTRODUCTION

Though the disease burden addressable by prehospital and out-of-hospital emergency care(OHEC) spans communicable diseases, maternal conditions, chronic conditions and injury, the single largest disability-adjusted life year burden contributor is injury, primarily driven by road traffic injuries(RTIs). Establishing OHEC for RTIs and other common emergencies in low- and middle-income countries(LMICs) where the injury burden is disproportionately greatest is a logical first step toward more comprehensive emergency medical services(EMS). However, with limited efforts to formalize and expand existing informal bystander care networks, there is a lack of consensus on how to develop and maintain bystander-driven Tier-1 EMS systems in LMICs. Resultantly, Tier-1 EMS development is fragmented among non-governmental organizations and the public sector globally.

METHODS

A steering committee coordinated a 9-round, modified Delphi-based expert discussion to identify current challenges, opportunities, and priorities in Tier-1 EMS development globally. 11 panelists represented seven Global Prehospital Consortium(GPC) member organizations with a mean 9.57 years of organizational Tier-1 EMS development/implementation experience(median = 9 years). The consortium represents the largest collaboration between organizations directing Tier-1 EMS programs globally across 12 countries on 3 continents(Americas, sub-Saharan Africa, and South Asia) with 22,000 first responders.

RESULTS

The GPC identified seven priority areas for Tier-1 EMS development: infrastructure/operations, communication, education/training, impact evaluation, financing, governance/legal, and transportation/equipment. A high level of consensus exists regarding priorities for investigation, including Tier-1 responder density/distribution, Tier-1 patient data variable standardization for trauma registries/quality improvement, dispatch technologies/protocols, modular curricula, broader cost-effectiveness and impact evaluation indices capturing secondary impacts of EMS, standardizing legal protections for first responders, and transportation/equipment standards.

DISCUSSION

Consensus is necessary to avoid duplicative and disorganized efforts due to the fragmented nature of parallel Tier-1 EMS efforts globally. A Delphi-like multi-round expert discussion among the members of the largest collaboration between organizations directing Tier-1 EMS programs globally generated relevant priorities to direct future efforts.

The Current Status and Challenges of Prehospital Trauma Care in Low- and Middle-Income Countries: A Systematic Review

BACKGROUND

This review aims to understand the present circumstances on the provision of prehospital trauma care in low- and middle-income countries (LMICs), particularly scoping the challenges experienced by LMICs in this regard. The objective is to systematically evaluate the currently available evidence on this topic. Based on the themes and challenges identified in the provision of prehospital trauma care in LMICs, we provide a series of recommendations and a knowledge base for future research in the field.

METHODS

A systematic database search was conducted of original articles that explored and reported on prehospital trauma care in LMIC in EMBASE, MEDLINE, Cochrane database, and Google Scholar, from inception to March 2022. All original articles reporting on prehospital trauma care from 2010 to 2022 in LMICs were assessed, excluding case reports, small case series, editorials, abstracts, and pre-clinical studies; those with data inconsistencies that impede data extraction; and those with study populations fewer than ten.

RESULTS

The literature search identified 2,128 articles, of which 29 were included in this review, featuring 27,848 participants from LMICs countries. Four main areas of focus within the studies were identified: (1) exploring emergency service systems, frameworks, and interconnected networks within the context of prehospital trauma care; (2) transportation of patients from the response site to hospital care; (3) medical education and the effects of first responder training in LMICs; and (4) cultural and social factors influencing prehospital trauma care-seeking behaviors. Due to overarching gaps in social and health care systems, significant barriers exist at various stages of providing prehospital trauma care in LMICs, particularly in injury identification, seeking treatment, transportation to hospital, and receiving timely treatment and post-intervention support.

CONCLUSION

The provision of prehospital trauma care in LMICs faces significant barriers at multiple levels, largely dependent on wider social, geographic, economic, and political factors impeding the development of such higher functioning systems within health care. However, there have been numerous breakthroughs within certain LMICs in different aspects of prehospital trauma care, supported to varying degrees by international initiatives, that serve as case studies for widespread implementation and targets. Such experiential learning is essential due to the heterogenous landscapes that comprise LMICs.

Evaluating feasibility of a novel mobile emergency medical dispatch tool for lay first responder prehospital response coordination in Sierra Leone: A simulation-based study

INTRODUCTION

The global injury burden, driven by road traffic injuries, disproportionately affects low- and middle-income countries, which lack robust emergency medical services (EMS) to address injury. The WHO recommends training lay first responders (LFRs) as the first step toward formal EMS development. Emergency medical dispatch (EMD) systems are the recognized next step but whether small groups of LFRs equipped with mobile dispatch infrastructure can efficiently respond to geographically-dispersed emergencies in a timely fashion and the quality of prehospital care provided is unknown.

MATERIALS AND METHODS

We piloted an EMD system utilizing a mobile phone application in Sierra Leone. Ten LFRs were randomly selected from a pool of 61 highly-active LFRs trained in 2019 and recruited to participate in an emergency simulation-based study. Ten simulation scenarios were created matching proportions of injury conditions across 1,850 previous incidents (June-December 2019). Fifty total simulations were launched in randomized order over 3 months, randomized along 10 km of highway in Makeni. Replicating real-world conditions, highly-active LFR participants were blinded to randomized dispatch timing/scenario to assess response time and skill performance under direct observation with a checklist using standardized patient actors. We used novel cost data tracked during EMD pilot implementation to inform the calculation of a new cost-effectiveness ratio ($USD cost per disability-adjusted life year averted (DALY)) for LFR programs equipped with dispatch, following WHOCHOICE guidelines, which state cost-effectiveness ratios less than gross domestic product (GDP) per capita are considered "very cost-effective."

RESULTS

Median total response interval (notification to arrival) was 5 min 39 s (IQR:0:03:51, 0:09:18). LFRs initially trained with a 5-hour curriculum and refresher training provide high-quality prehospital care during simulated emergencies. Median first aid skill checklist completion was 89% (IQR: 78%, 90%). Cost-effectiveness equals $179.02USD per DALY averted per 100,000 people, less than Sierra Leonean GDP per capita ($484.52USD).

CONCLUSION

LFRs equipped with mobile dispatch demonstrate appropriate response times and effective basic initial management of simulated emergencies. Training smaller cohorts of highly-active LFRs equipped with mobile dispatch appears highly cost-effective and may be a feasible model to facilitate efficient dispatch to expand emergency coverage while conserving valuable training resources in resource-limited settings.

Assessment of knowledge, attitude and practice of first aid among taxi operators in a Kampala City Taxi Park, Uganda: A cross-sectional study

INTRODUCTION

Road traffic accidents are among the leading causes of death in Uganda. Taxi operators are at a high risk of RTA and can potentially be first responders. This study, aimed to assess knowledge, attitude, and practice of first aid among taxi operators in the new taxi park, Kampala Uganda.

METHODS

A descriptive cross-sectional study was conducted in 2021 among taxi drivers and conductors in the New Taxi Park, Kampala City, Uganda. A semi-structured questionnaire was used to collect quantitative data from taxi operators after informed consent. Chi-square or Fisher's exact test and logistic regression were performed in STATA 16 to assess the association between first aid knowledge and demographics. P < 0.05 was statistically significant.

RESULTS

A total of 345 participants, majority males (n = 338, 98%) aged between 18 and 45 years (76.5%), were recruited. Although 97.7% (n = 337) had heard about first aid, only 19.4% (n = 67) had prior first aid training. Overall mean knowledge score was 40.1% (SD = 14.5%), with 29.9% (n = 103) having good knowledge (≥50%). Participants who had witnessed more than five accidents (aOR = 2.9, 95% CI = 1.7-4.8, p < 0.001), those with first aid kits (aOR = 1.7, 95% CI = 1.0-3.0, p = 0.38) were more likely to have good knowledge while those below post-secondary education level i.e., Primary (AOR = 0.2, 95% CI = 0.1-0.5, p ≤0.001) and secondary (aOR = 0.2, 95% CI = 0.1-0.6, p = 0.001), were less likely to have good knowledge. About 97% and 93% perceived first aid as important and were willing to undergo training, respectively; however, only 69% were willing to give first aid. Only 181(52.5%) had ever attended to accident victims.

CONCLUSION

Majority of taxi operators had poor first aid knowledge. Factors associated with good knowledge included level of education, number of accidents witnessed, having first aid kits. Although their attitudes were favorable, practice was poor. Comprehensive training and refresher courses can help increase first aid knowledge, and improving practice.

Prehospital care for traumatic spinal cord injury by first responders in 8 sub-Saharan African countries and 6 other low- and middle-income countries: A scoping review

INTRODUCTION

Traumatic spinal cord injury (TSCI) constitutes a considerable portion of the global injury burden, disproportionately affecting low- and middle-income countries (LMICs). Prehospital care can address TSCI morbidity and mortality, but emergency medical services are lacking in LMICs. The current standard of prehospital care for TSCI in sub-Saharan Africa and other LMICs is unknown.

METHODS

This review sought to describe the state of training and resources for prehospital TSCI management in sub-Saharan Africa and other LMICs. Articles published between 1 January 1995 and 1 March 2020 were identified using PMC, MEDLINE, and Scopus databases following PRISMA-ScR guidelines. Inclusion criteria spanned first responder training programs delivering prehospital care for TSCI. Two reviewers assessed full texts meeting inclusion criteria for quality using the Newcastle-Ottawa Scale and extracted relevant characteristics to assess trends in the state of prehospital TSCI care in sub-Saharan Africa and other LMICs.

RESULTS

Of an initial 482 articles identified, 23 met inclusion criteria, of which ten were set in Africa, representing eight countries. C-spine immobilization precautions for suspected TSCI patients is the most prevalent prehospital TSCI intervention for and is in every LMIC first responder program reviewed, except one. Numerous first responder programs providing TSCI care operate without C-collar access (n = 13) and few teach full spinal immobilization (n = 5). Rapid transport is most frequently reported as the key mortality-reducing factor (n = 11). Despite more studies conducted in the Southeast Asia/Middle East (n = 13), prehospital TSCI studies in Africa are more geographically diverse, but responder courses are shorter, produce fewer professional responders, and have limited C-collar availability.

DISCUSSION

Deficits in training and resources to manage TSCI highlights the need for large prospective trials evaluating alternative C-spine immobilization methods for TCSI that are more readily available across diverse LMIC environments and the importance of understanding resource variability to sustainably improve prehospital TSCI care.
