The state of emergency medical services and acute health facility care in Uganda: findings from a National Cross-Sectional Survey

New Trauma Score versus Kampala Trauma Score II in predicting mortality following road traffic crash: a prospective multi-center cohort study

INTRODUCTION

Mortality due to injuries disproportionately impact low income countries. Knowledge of who is at risk of poor outcomes is critical to guide resource allocation and prioritization of severely injured. Kampala Trauma Score (KTS), developed in 1996 and last modified in 2002 as KTS II, is still widely being used to predict injury outcomes in resource-limited settings with no further revisions in the past two decades, despite ongoing criticism of some of its parameters. The New Trauma Score (NTS), a recent development in 2017, has shown potential in mortality prediction, but a dearth of evidence exist regarding its performance in the African population.

OBJECTIVES

To compare NTS to the modified Kampala Trauma Score (KTS II) in the prediction of 30-day mortality, and injury severity amongst patients sustaining road traffic crashes in Ugandan low-resource settings.

METHODS

Multi-center prospective cohort study of patients aged 15 years and above. Of the 194 participants, 85.1% were males with a mean age of 31.7 years. NTS and KTS II were determined for each participant within 30-minutes of admission and followed-up for 30 days to determine their injury outcomes. The sensitivity, specificity, and area under receiver operating characteristics curve (AUC) for predicting mortality were compared between the two trauma scores using SPSS version 22. Ethical clearance: Research and Ethics Committee of Kampala International University Western Campus (Ref No: KIU-2022-125).

RESULTS

The injury severity classifications based on NTS vs. KTS II were mild (55.7% vs. 25.8%), moderate (29.9% vs. 30.4%), and severe (14.4% vs. 43.8%). The mortality rates for each injury severity category based on NTS vs. KTS II were mild (0.9% v 0%), moderate (20.7% vs. 5.1%), and severe (50% vs. 28.2%). The AUC was 0.87 for NTS (95% CI 0.808-0.931) vs. 0.86 (95% CI 0.794-0.919) for KTS II respectively. The sensitivity of NTS vs. KTS II in predicting mortality was 92.6% (95% CI: 88.9-96.3) vs. 70.4% (95% CI: 63.0-77.8) while the specificity was 70.7% (95% CI: 64.2-77.2) vs. 78.4% (95% CI: 72.1-84.7) at cut off points of 17 for NTS and 6 for KTS II respectively.

CONCLUSIONS

NTS was more sensitive but its specificity for purposes of 30-day mortality prediction was lower compared to KTS II. Thus, in low-resourced trauma environment where time constraints and pulse oximeters are of concern, KTS II remains superior to NTS.

Effect of Rural Trauma Team Development on the Outcomes of Motorcycle Accident-Related Injuries (Motor Registry Project): Protocol for a Multicenter Cluster Randomized Controlled Trial

BACKGROUND

Injury is a global health concern, and injury-related mortality disproportionately impacts low- and middle-income countries (LMICs). Compelling evidence from observational studies in high-income countries shows that trauma education programs, such as the Rural Trauma Team Development Course (RTTDC), increase clinician knowledge of injury care. There is a dearth of such evidence from controlled clinical trials to demonstrate the effect of the RTTDC on process and patient outcomes in LMICs.

OBJECTIVE

This multicenter cluster randomized controlled clinical trial aims to examine the impact of the RTTDC on process and patient outcomes associated with motorcycle accident-related injuries in an African low-resource setting.

METHODS

This is a 2-arm, parallel, multi-period, cluster randomized, controlled, clinical trial in Uganda, where rural trauma team development training is not routinely conducted. We will recruit regional referral hospitals and include patients with motorcycle accident-related injuries, interns, medical trainees, and road traffic law enforcement professionals. The intervention group (RTTDC) and control group (standard care) will include 3 hospitals each. The primary outcomes will be the interval from the accident to hospital admission and the interval from the referral decision to hospital discharge. The secondary outcomes will be all-cause mortality and morbidity associated with neurological and orthopedic injuries at 90 days after injury. All outcomes will be measured as final values. We will compare baseline characteristics and outcomes at both individual and cluster levels between the intervention and control groups. We will use mixed effects regression models to report any absolute or relative differences along with 95% CIs. We will perform subgroup analyses to evaluate and control confounding due to injury mechanisms and injury severity. We will establish a motorcycle trauma outcome (MOTOR) registry in consultation with community traffic police.

RESULTS

The trial was approved on August 27, 2019. The actual recruitment of the first patient participant began on September 01, 2019. The last follow-up was on August 27, 2023. Posttrial care, including linkage to clinical, social support, and referral services, is to be completed by November 27, 2023. Data analyses will be performed in Spring 2024, and the results are expected to be published in Autumn 2024.

CONCLUSIONS

This trial will unveil how a locally contextualized rural trauma team development program impacts organizational efficiency in a continent challenged with limited infrastructure and human resources. Moreover, this trial will uncover how rural trauma team coordination impacts clinical outcomes, such as mortality and morbidity associated with neurological and orthopedic injuries, which are the key targets for strengthening trauma systems in LMICs where prehospital care is in the early stage. Our results could inform the design, implementation, and scalability of future rural trauma teams and trauma education programs in LMICs.

Rural trauma team development training amongst medical trainees and traffic law enforcement professionals in a low-income country: a protocol for a prospective multicenter interrupted time series

Background

Road traffic injuries and their resulting mortality disproportionately affect rural communities in low-middle-income countries (LMICs) due to limited human and infrastructural resources for postcrash care. Evidence from high-income countries show that trauma team development training could improve the efficiency, care, and outcome of injuries. A paucity of studies have evaluated the feasibility and applicability of this concept in resource constrained settings. The aim of this study protocol is to establish the feasibility of rural trauma team development and training in a cohort of medical trainees and traffic law enforcement professionals in Uganda.

Methods

Muticenter interrupted time series of prospective interventional trainings, using the rural trauma team development course (RTTDC) model of the American College of Surgeons. A team of surgeon consultants will execute the training. A prospective cohort of participants will complete a before and after training validated trauma related multiple choice questionnaire during September 2019-November 2023. The difference in mean prepost training percentage multiple choice questionnaire scores will be compared using ANOVA-test at 95% CI. Time series regression models will be used to test for autocorrelations in performance. Acceptability and relevance of the training will be assessed using 3 and 5-point-Likert scales. All analyses will be performed using Stata 15.0. Ethical approval was obtained from Research and Ethics Committee of Mbarara University of Science and Technology (Ref: MUREC 1/7, 05/05-19) and Uganda National Council for Science and Technology (Ref: SS 5082). Retrospective registration was accomplished with Research Registry (UIN: researchregistry9490).

Understanding pediatric surgical needs in North Korea: a modeling analysis

Background

Sixty-five percent of children worldwide lack access to surgical care, the majority of whom live in low-income and middle-income countries (LMICs). Developing surgical infrastructure requires information on surgical need; however, this information is often limited in LMICs. North Korea (Democratic People's Republic of Korea, DPRK) has a low amount of publicly available data. Here, we analyzed available modeled data to understand the causes of pediatric deaths due to conditions treatable with surgery in DPRK.

Methods

We used World Bank data and models from the Institute for Health Metrics and Evaluation to identify causes of pediatric deaths affecting pediatric patients (age <20 years). We compared mortality of disease between DPRK and countries with similar economic status.

Results

Between 1990 and 2019, the number of overall pediatric deaths has decreased. In 2019, 32.2% of all pediatric deaths in DPRK were caused by surgical conditions. The leading categories of surgical conditions were injuries (53.9%), congenital conditions (34.2%), tumors (8.8%), and abdominal conditions (3.2%). DPRK has a lower relative rate of pediatric deaths compared with other LMICs with similar gross domestic product per capita. However, it has a higher relative rate of pediatric deaths due to conditions requiring treatment with surgery. Transport injuries contribute significantly to the high rate of pediatric deaths in DPRK.

Conclusions

Although DPRK may be allocating overall resources toward pediatric healthcare more efficiently than economic peers, DPRK may benefit from improvement in pediatric surgical capacity. Improved availability of data and close international collaboration could be potential solutions to bridge this gap.

Description and analysis of the emergency obstetric interfacility ambulance transfers (IFTs) to Kawempe National Referral Hospital in Uganda

Introduction

In Uganda, 2% of women die from maternal causes with a mortality rate of 336 maternal deaths per 100,000 live births. According to the World Health Organization Uganda is one of the top three contributors to maternal mortality in sub-Saharan Africa. Uganda has parallel weak ambulance systems, government, and non-government-owned, that transport obstetric emergencies to higher-level facilities. These two operations lack standards of medical care and inter-facility transfer (IFT) protocols to direct care. Limited studies exist which assess the state of Emergency Care Services in Uganda and none has been performed to assess the ambulance referral services utilized to address obstetric emergencies.

Objective

The present study was performed to describe the ambulance transfer processes of obstetric emergencies by analyzing cases arriving at Kawempe National Referral Hospital (KNRH) from outlying health facilities.

Methods

The study was based at KNRH in Kampala, Uganda. It was a descriptive and analytic cross-sectional study. Trained research assistants enrolled participating patients who met the inclusion criteria consecutively on arrival by ambulance at the hospital. Utilizing a questionnaire, quantitative data was collected from the ambulance driver, the sending facility referral form, and the receiving hospital's ambulance log book for each case. The sample size was 215.

Results

The median age was 27 years and the majority of patients were referred because of hypertensive disorders (34.9%), obstructed labor (26.5%) and hemorrhage (20.9%). The median total response time for transfer of obstetric emergencies was 50 min, from ambulance activation until the mother was received at KNRH. Differences were identified between government and non-government-owned ambulances in regards to the method of activation, medical escort staffing, number of vital signs recorded, and ambulance onboard medical care. Ambulances parked at the facility took the shortest transfer time and EMT-supported ambulances had the greatest number of vital signs taken.

Conclusions

Recommendations are to develop an integrated ambulance system for both government and non-government ambulances with standards especially in regards to standardized scripted call-center calls analysis, dispatch activation time, response-to-patient time, and trained ambulance professional staffing and medical care whenever in patient transport mode.

Strengthening Kampala's Urban Referral System for Maternal and Newborn Care Through Establishment of an Emergency Call and Dispatch Center

INTRODUCTION

Most pregnant women living in urban slum communities in Uganda deliver at public health centers that are not equipped to provide emergency obstetric and newborn care. When obstetric emergencies occur, pregnant women are referred to a higher-level facility and are responsible for arranging and paying for their own transport. The Kampala Slum Maternal Newborn (MaNe) project developed and tested an emergency call and ambulance dispatch center and a mobile application to request, deploy, and track ambulances. We describe the development of these 2 interventions and findings on the feasibility, acceptability, and sustainability of the interventions.

METHODS

MaNe conducted a mixed-method feasibility study that included an assessment of the acceptability and demand of the interventions. In-depth interviews (N=26) were conducted with facility proprietors, health providers, ambulance drivers, Kampala Capital City Authority officers, and community members to understand the successes and challenges of establishing the call center and developing the mobile application. Thematic content analysis was done. Quantitative data from the call center dispatch logs were analyzed descriptively to complement the qualitative findings.

FINDINGS

Between April 2020 and June 2021, 10,183 calls were made to the emergency call and dispatch center. Of these, 25% were related to maternal and newborn health emergencies and 14% were COVID-19 related. An ambulance was dispatched to transfer or evacuate a patient in 35% of the calls. Participants acknowledged that the call center and mobile application allowed for efficient communication, coordination, and information flow between health facilities. Supportive district leadership facilitated the establishment of the call center and has taken over the operating costs of the center.

CONCLUSION

The call center and referral application improved the coordination of drivers and ambulances and allowed facilities to prepare for and treat cases more efficiently.

Leveraging tele-mentoring and remote learning to strengthen the emergency care capacity of health workers in Uganda

Background

A robust emergency care system is a cost-effective method of reducing preventable death and disability, especially in low-and middle-income countries. To scale emergency care expertise across the country, the Uganda Ministry of Health and Seed Global Health established the Emergency Medical Services (EMS) ECHO program. We describe the process of establishing the program in a resource-limited setting, best practices, and lessons learned in Uganda.

Methods

Investigators conducted a mixed-methods evaluation to assess the initial 4 months' implementation of the EMS ECHO. We conducted pre/post-program assessments of healthcare worker knowledge, self-efficacy, and professional's satisfaction with the program. The analysis compared the differences between pre/post-test scores descriptively.

Results

The EMS ECHO was initiated in November 2021. A phased curriculum was developed with the initial phase focusing on the ABCDE (Airway, Breathing, Circulation, Disability, and Exposure) approach to the emergency patient. This phase reached 2,030 health workers cumulatively across 200 health facilities. The majority of the participants were medical doctors (n = 751, 37%), and nurses (n = 568, 28%). Majority of participants (95%) rated the sessions as informative. On whether the ECHO sessions diminished professional isolation, 66% agreed or strongly agreed.

Conclusions

Similar to other ECHO program evaluation results, Uganda's EMS ECHO program improved knowledge, skills, and the development of a virtual community of practice thereby diminishing professional isolation. It also demonstrates that through a planned stepwise process, virtual learning and telementorship can be used efficiently to improve healthcare worker knowledge,skills and multiply the limited number of emergency care experts available in the country.

Cost-effectiveness analysis of the multi-strategy WHO emergency care toolkit in regional referral hospitals in Uganda

BACKGROUND

Low- and middle-income countries bear a disproportionate amount of the global burden of disease from emergency conditions. To improve the provision of emergency care in low-resource settings, a multifaceted World Health Organization (WHO) intervention introduced a toolkit including Basic Emergency Care training, resuscitation area guidelines, a trauma registry, a trauma checklist, and triage tool in two public hospital sites in Uganda. While introduction of the toolkit revealed a large reduction in the case fatality rate of patients, little is known about the cost-effectiveness and affordability. We analysed the cost-effectiveness of the toolkit and conducted a budget analysis to estimate the impact of scale up to all regional referral hospitals for the national level.

METHODS

A decision tree model was constructed to assess pre- and post-intervention groups from a societal perspective. Data regarding mortality were drawn from WHO quality improvement reports captured at two public hospitals in Uganda from 2016-2017. Cost data were drawn from project budgets and included direct costs of the implementation of the intervention, and direct costs of clinical care for patients with disability. Development costs were not included. Parameter uncertainty was assessed using both deterministic and probabilistic sensitivity analyses. Our model estimated the incremental cost-effectiveness of implementing the WHO emergency care toolkit measuring all costs and outcomes as disability-adjusted life-years (DALYs) over a lifetime, discounting both costs and outcomes at 3.5%.

RESULTS

Implementation of the WHO Toolkit averted 1,498 DALYs when compared to standard care over a one-year time horizon. The initial investment of $5,873 saved 34 lives (637 life years) and avoided $1,670,689 in downstream societal costs, resulted in a negative incremental cost-effectiveness ratio, dominating the comparator scenario of no intervention. This would increase to saving 884 lives and 25,236 DALYs annually with national scale up. If scaled to a national level the total intervention cost over period of five years would be $4,562,588 or a 0.09% increase of the total health budget for Uganda. The economic gains are estimated to be $29,880,949 USD, the equivalent of a 655% return on investment. The model was most sensitive to average annual cash income, discount rate and frequency survivor is a road-traffic incident survivor, but was robust for all other parameters.

CONCLUSION

Improving emergency care using the WHO Toolkit produces a cost-savings in a low-resource setting such as Uganda. In alignment with the growing body of literature highlighting the value of systematizing emergency care, our findings suggest the toolkit could be an efficient approach to strengthening emergency care systems.

The epidemiology and characteristics of injuries to under 5's in a secondary city in Uganda: a retrospective review of hospital data

Child injuries are largely preventable yet cause significant mortality and morbidity globally. Injury data from low-income countries is limited for children under the age of 5 and therefore the current understanding of the magnitude of injuries in this age group is low. Hospital-based registries are one mechanism by which injury data can be gathered. This paper presents findings from a retrospective hospital record review of 4 hospitals in Jinja, a rural setting in Uganda, involving the extraction of data for children under the age of 5-years who sustained an injury during a 6-month period in 2019. A total of 225 injury cases were retrieved from the hospitals. Over half (57.3%) of the events occurred among males. The majority (92%) suffered one injury per injury event. Most of the injuries occurred among those aged 13 to 24 months (32.9%). Burns (32%) and cuts (20%) were the most common cause of injury. This study presents a hospital-based analysis of injuries amongst under 5's in rural Uganda. It provides information on the characteristics of children entering healthcare facilities in Uganda and highlights the burden of paediatric injuries in the hospital setting.

Emergency medicine physician supervision and mortality among patients receiving care from non-physician clinicians in a task-sharing model of emergency care in rural Uganda: a retrospective analysis of a single-centre training programme

OBJECTIVES

To assess the association between emergency medicine physician supervision and 3-day mortality for patients receiving care from non-physician clinicians in a task-sharing model of emergency care in rural Uganda.

DESIGN

Retrospective cohort analysis with multivariable logistic regression.

SETTING

Single rural Ugandan emergency unit.

PARTICIPANTS

All patients presenting for care from 2009 to 2019.

INTERVENTIONS

Three cohorts of patients receiving care from non-physician clinicians had three different levels of physician supervision: 'Direct Supervision' (2009-2010) emergency medicine physicians directly supervised all care; 'Indirect Supervision' (2010-2015) emergency medicine physicians were consulted as needed; 'Independent Care' (2015-2019) no emergency medicine physician supervision.

PRIMARY OUTCOME MEASURE

Three-day mortality.

RESULTS

38 033 ED visits met inclusion criteria. Overall mortality decreased significantly across supervision cohorts ('Direct' 3.8%, 'Indirect' 3.3%, 'Independent' 2.6%, p<0.001), but so too did the rates of patients who presented with ≥3 abnormal vitals ('Direct' 32%, 'Indirect' 19%, 'Independent' 13%, p<0.001). After controlling for vital sign abnormalities, 'Direct' and 'Indirect' supervision were both significantly associated with reduced OR for mortality ('Direct': 0.57 (0.37 to 0.90), 'Indirect': 0.71 (0.55 to 0.92)) when compared with 'Independent Care'. Sensitivity analysis showed that this mortality benefit was significant for the minority of patients (17.2%) with ≥3 abnormal vitals ('Direct': 0.44 (0.22 to 0.85), 'Indirect': 0.60 (0.41 to 0.88)), but not for the majority (82.8%) with two or fewer abnormal vitals ('Direct': 0.81 (0.44 to 1.49), 'Indirect': 0.82 (0.58 to 1.16)).

CONCLUSIONS

Emergency medicine physician supervision of emergency care non-physician clinicians is independently associated with reduced overall mortality. This benefit appears restricted to the highest risk patients based on abnormal vitals. With over 80% of patients having equivalent mortality outcomes with independent non-physician clinician emergency care, a synergistic model providing variable levels of emergency medicine physician supervision or care based on patient acuity could safely address staffing shortages.

Training and certification in first responder care among mountaineering practitioners in east Africa

•

In mountaineering, within East Africa, medical care may be very far away from the emergency scenes, and hence the tier one emergency care system may be offered by the mountaineering practitioners.

•

There is limited research in the first responder care programmes in the mountaineering wilderness environments in Africa.

•

Competency in first responder care through training and certification is part of safety promotion, a factor that can offer more confidence and appeal to tourists towards participation in mountaineering activities in Africa.

Introduction

Mountaineering activities have potential risks for injuries and illnesses. Extreme weather conditions, high altitude, limited resources and accessibility to transport and definitive medical services calls for mountaineering practitioners to be well prepared through training and certification in first responder care. This is useful in cases when they have an injured climber and need to offer support in the tier-one emergency system care before accessing further care in a medical facility. The study sought to establish the first responder care training status of mountaineering practitioners and the associations of mountaineering practitioners’ first responder care training levels and gender, age, years of work experience, and designation.

Methods

The study used cross-sectional analytical research design with a purposive sample of one hundred and thirty six (136) mountaineering practitioners in East Africa. Snowball sampling procedure was used to identify the respondents since there were no records indicating the population size or specific location of these mountaineering practitioners. A self-administrated questionnaire was used to collect data on whether they were trained or not; status of their up-to-date certification; institutions where they did their training and recertification; and their training levels in first responder care, which would cover the aim of the study.

Results

Majority of mountaineering practitioners (91.2%) had received some form of training. However, 47.1% had received training in basic first aid, which did not involve mountain related components. Outdoor practitioners’ up-to-date training was dependent on their age (p = 0.005), and years of work experience (p= 0.014).

Discussion

There is need for mountaineering practitioners to have standardized minimum training in wilderness specific first responder care. The study recommends that the training and recertification should be undertaken on a regular basis by the mountaineering practitioners in East Africa.

Exploring country-wide equitable government health care facility access in Uganda

Background

Rural access to health care remains a challenge in Sub-Saharan Africa due to urban bias, social determinants of health, and transportation-related barriers. Health systems in Sub-Saharan Africa often lack equity, leaving disproportionately less health center access for the poorest residents with the highest health care needs. Lack of health care equity in Sub-Saharan Africa has become of increasing concern as countries enter a period of simultaneous high infectious and non-communicable disease burdens, the second of which requires a robust primary care network due to a long continuum of care. Bicycle ownership has been proposed and promoted as one tool to reduce travel-related barriers to health-services among the poor.

Methods

An accessibility analysis was conducted to identify the proportion of Ugandans within one-hour travel time to government health centers using walking, bicycling, and driving scenarios. Statistically significant clusters of high and low travel time to health centers were calculated using spatial statistics. Random Forest analysis was used to explore the relationship between poverty, population density, health center access in minutes, and time saved in travel to health centers using a bicycle instead of walking. Linear Mixed-Effects Models were then used to validate the performance of the random forest models.

Results

The percentage of Ugandans within a one-hour walking distance of the nearest health center II is 71.73%, increasing to 90.57% through bicycles. Bicycles increased one-hour access to the nearest health center III from 53.05 to 80.57%, increasing access to the tiered integrated national laboratory system by 27.52 percentage points. Significant clusters of low health center access were associated with areas of high poverty and urbanicity. A strong direct relationship between travel time to health center and poverty exists at all health center levels. Strong disparities between urban and rural populations exist, with rural poor residents facing disproportionately long travel time to health center compared to wealthier urban residents.

Conclusions

The results of this study highlight how the most vulnerable Ugandans, who are the least likely to afford transportation, experience the highest prohibitive travel distances to health centers. Bicycles appear to be a “pro-poor” tool to increase health access equity.

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

BACKGROUND

The WHO recommends training lay first responders (LFRs) as the first step towards establishing emergency medical services (EMS) in low-income and middle-income countries. Understanding social and financial benefits associated with responder involvement is essential for LFR programme continuity and may inform sustainable development.

METHODS

A mixed-methods follow-up study was conducted in July 2019 with 239 motorcycle taxi drivers, including 115 (75%) of 154 initial participants in a Ugandan LFR course from July 2016, to evaluate LFR training on participants. Semi-structured interviews and surveys were administered to samples of initial participants to assess social and economic implications of training, and non-trained motorcycle taxi drivers to gauge interest in LFR training. Themes were determined on a per-question basis and coded by extracting keywords from each response until thematic saturation was achieved.

RESULTS

Three years post-course, initial participants reported new knowledge and skills, the ability to help others, and confidence gain as the main benefits motivating continued programme involvement. Participant outlook was unanimously positive and 96.5% (111/115) of initial participants surveyed used skills since training. Many reported sensing an identity change, now identifying as first responders in addition to motorcycle taxi drivers. Drivers reported they believe this led to greater respect from the Ugandan public and a prevailing belief that they are responsible transportation providers, increasing subsequent customer acquisition. Motorcycle taxi drivers who participated in the course reported a median weekly income value that is 24.39% higher than non-trained motorcycle taxi counterparts (p<0.0001).

CONCLUSIONS

A simultaneous delivery of sustained social and perceived financial benefits to LFRs are likely to motivate continued voluntary participation. These benefits appear to be a potential mechanism that may be leveraged to contribute to the sustainability of future LFR programmes to deliver basic prehospital emergency care in resource-limited settings.
