Development and Implementation of Short Courses to Support the Establishment of a Prehospital System in Sub-Saharan Africa: Lessons Learned from Tanzania

Education and training of prehospital first responders in low- and middle-income countries

Prehospital emergency medical services play a vital role in providing essential emergency medical and trauma care. However, in many low- and middle-income countries, there is a significant lack of adequate emergency medical services coverage, a problem compounded by a profound deficit of first responder training programs. The African Federation of Emergency Medicine classifies prehospital emergency care into 2 categories: tier-1, which includes laypersons, and tier-2, consisting of professionals equipped with dispatch capabilities. Both tier-1 and tier-2 first responders require protocolized training, integration, and coordination to varying degrees, with tier-1 programs focusing primarily on immediate stabilization and hospital transportation and tier-2 programs dedicating increased focus toward formal dispatch and advanced life support interventions. Training for both tiers of emergency medical services typically involves in-person didactic lectures with practical skills sessions. However, the content of these courses is highly context-dependent, and there is no international consensus regarding pedagogical methods or curriculum content for first responder training in low- and middle-income countries. Similarly, there is a lack of consensus in monitoring and evaluating training programs, including assessment methods, passing scores, and certification requirements. Although many programs use knowledge or skills acquisition testing, the content and depth of these examinations vary greatly, and long-term follow-up reporting is limited. As such, the educational landscape of both tier-1 and tier-2 emergency medical services in low- and middle-income countries remains highly varied and often faces a dual challenge of lacking clear international guidelines while still maintaining local appropriateness. Modular curricula developed in conjunction with standardized needs assessments, accompanied by the adoption of the training of trainers model, may present a pathway for local adaptability by leveraging local community members to inform and proliferate training. Although there have been notable improvements in prehospital training programs in resource-limited settings during the past 3 decades, challenges related to maintaining fidelity in monitoring and evaluation, expanding programs within resource constraints, and adapting to specific contexts continue to offer opportunities for further development in the future.

Patterns and Predictors of Timely Presentation and Outcomes of Polytrauma Patients Referred to the Emergency Department of a Tertiary Hospital in Tanzania

Background

Polytrauma patients require special facilities to care for their injuries. In HICs, these patients are rapidly transferred from the scene or the first-health facility directly to a trauma center. However, in many LMICs, prehospital systems do not exist and there are long delays between arrivals at the first-health facility and the trauma center. We aimed to quantify the delay and determine the predictors of mortality among polytrauma patients. Methodology. We consecutively enrolled adult polytrauma patients (≥18 years) with ISS >15 referred to the Emergency Medicine Department of Muhimbili National Hospital, a major trauma center in Tanzania between August 2019 and January 2020. Based on a pilot study, the arrival of >6 hours after injury was considered a delay. The outcome of interest was factors associated with delayed presentation and the association of timeliness with 7-day mortality.

Results

We enrolled 120 (4.5%) referred polytrauma adult patients. The median age was 30 years (IQR 25-39) and the ISS was 29 (IQR 24-34). The majority (85%) were males. While the median time from injury to first-health facility was 40 minutes (IQR 33-50), the median time from injury to arrival at EMD-MNH, was 377 minutes (IQR 314-469). Delayed presentation was noted in more than half (54.2%) of participants, with the odds of dying being 1.4 times higher in the delayed group (95% CI 0.3-5.6). Having a GCS <8 (AOR 16.3 (95% CI 3.1-86.3), hypoxia <92% (AOR 8.3 (95% CI 1.4-50.9), and hypotension <90 mmHg (R 7.3 (95% CI 1.6-33.6) were all independent predictors of mortality.

Conclusion

The majority of polytrauma patients arrive at the tertiary facilities delayed for more than 6 hours and a distance of more than 8 km between facilities is associated with delay. Hypotension, hypoxia, and GCS of less than 8 are independent predictors of poor outcome. In the interim, there is a need to expedite the transfer of polytrauma patients to trauma care capable centers.

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.

Epidemiology of prehospital trauma deaths in Malawi: A retrospective cohort study

Introduction

Trauma is among the leading causes of death and disability in both adults and children worldwide. In Malawi, trauma patients are commonly brought in dead (BID). We aimed to describe the prevalence, sociodemographic, and injury-related characteristics of patients BID to Kamuzu Central Hospital (KCH), a referral hospital in Lilongwe, Malawi.

Methods

We retrospectively reviewed records of all patients BID in the trauma surveillance registry at KCH from February 2008 to September 2019. We excluded patients BID that did not present to the emergency centre, and were instead taken to the mortuary directly. We used descriptive statistics to evaluate the epidemiology of patients BID.

Results

We reviewed 106,198 trauma records and 1889 (1.8%) were BID patients. Most patients BID were male, in both adult (n = 1337/1528, 88.4%) and children (n = 231/360, 64.9%) cohorts. The mean age was 34.7 (SD 11.9) years in adults and 7.8 (SD 5.4) years in children. Among the adult BID patients, 33.2% were unemployed, 25.6% were construction workers, and 10.1% were small business owners or managers. The common injury mechanisms in adults were road traffic-related injuries (RTIs) (47.1%) and assaults (23.6%). In children, injuries resulted from RTIs (39.7%), with 74.4% of those were pedestrians hit by cars, drowning (22.9%), and burns (12.4%). In both groups, most injuries occurred on roads (60.2%) or at home (22.1%). Reported alcohol use at the time of trauma was present in 6.3%. The police (57.9%) and privately-owned vehicles (26.6%) transported most BID patients to KCH.

Conclusion

Efforts to reduce prehospital trauma mortality must focus on improving prehospital care, including training the police and community in basic life support and improving resources towards prehospital trauma care. Further efforts to reduce prehospital mortality must aim to decrease injuries on the roads and at home.
