Defining measures of emergency care access in low-income and middle-income countries: a scoping review.

BACKGROUND: Over 50% of annual deaths in low-income and middle-income countries (LMICs) could be averted through access to high-quality emergency care. OBJECTIVES: We performed a scoping review of the literature that described at least one measure of emergency care access in LMICs in order to understand relevant barriers to emergency care systems. ELIGIBILITY CRITERIA: English language studies published between 1 January 1990 and 30 December 2020, with one or more discrete measure(s) of access to emergency health services in LMICs described. SOURCE OF EVIDENCE: PubMed, Embase, Web of Science, CINAHL and the grey literature. CHARTING METHODS: A structured data extraction tool was used to identify and classify the number of 'unique' measures, and the number of times each unique measure was studied in the literature ('total' measures). Measures of access were categorised by access type, defined by Thomas and Penchansky, with further categorisation according to the 'Three Delay' model of seeking, reaching and receiving care, and the WHO's Emergency Care Systems Framework (ECSF). RESULTS: A total of 3103 articles were screened. 75 met full study inclusion. Articles were uniformly descriptive (n=75, 100%). 137 discrete measures of access were reported. Unique measures of accommodation (n=42, 30.7%) and availability (n=40, 29.2%) were most common. Measures of seeking, reaching and receiving care were 22 (16.0%), 46 (33.6%) and 69 (50.4%), respectively. According to the ECSF slightly more measures focused on prehospital care-inclusive of care at the scene and through transport to a facility (n=76, 55.4%) as compared with facility-based care (n=57, 41.6%). CONCLUSIONS: Numerous measures of emergency care access are described in the literature, but many measures are overaddressed. Development of a core set of access measures with associated minimum standards are necessary to aid in ensuring universal access to high-quality emergency care in all settings.

Application of the World Health Organization's Basic Emergency Care course in Zambia.

BACKGROUND: In 2013, the Zambian Ministry of Health identified action priorities for strengthening their emergency care system; one of these priorities was emergency care training for healthcare providers. To rapidly train the existing cadre of frontline providers, trainings were implemented in multiple provinces using the World Health Organization's Basic Emergency Care (BEC) course. The BEC course is open-access and emphasizes a practical syndrome-based approach to critical emergency conditions. This paper describes the first reported larger scale educational intervention of the BEC course in 7 provinces of Zambia. METHODS: Course delivery occurred at seven Zambian hospitals selected by the Ministry of Health over a 1 year period. Participant emergency care knowledge was assessed pre- and post-course with a 25-question multiple choice exam. Participant confidence levels related to emergency care provision and emergency care skills were assessed pre- and post-course using a Likert scale survey. RESULTS: Overall, 210 participants were trained at 7 sites. Participants demonstrated significant improvements in their multiple-choice exam scores; the overall pre-course mean was 61.47, and the post-course mean was 79.87 (p < 0.0001). Self-reported confidence in the care of ill and injured adults and children increased after taking the course, and participants generally agreed that the BEC course was highly valuable and applicable to local needs. CONCLUSION: Implementation of the WHO's BEC course at seven hospitals throughout Zambia led to improvement in the participants' emergency care knowledge and confidence levels at all sites. The BEC course has the potential to be implemented in a nationwide initiative but would require allocation of significant human and physical resources. Additional work evaluating patient outcomes and long-term participant educational outcomes is needed.

Emergency Medicine Training Programs in Low- and Middle-Income Countries: A Systematic Review.

Background: Despite the growing interest in the development of emergency care systems and emergency medicine (EM) as a specialty globally, there still exists a significant gap between the need for and the provision of emergency care by specialty trained providers. Many efforts to date to expand the practice of EM have focused on programs developed through partnerships between higher- and lower-resource settings. Objective: To systematically review the literature to evaluate the composition of EM training programs in low- and middle-income countries (LMICs) developed through partnerships. Methods: An electronic search was conducted using four databases for manuscripts on EM training programs - defined as structured education and/or training in the methods, procedures, and techniques of acute or emergency care - developed through partnerships. The search produced 7702 results. Using a priori inclusion and exclusion criteria, 94 manuscripts were included. After scoring these manuscripts, a more in-depth examination of 26 of the high-scoring manuscripts was conducted. Findings: Fifteen highlight programs with a focus on specific EM content (i.e. ultrasound) and 11 cover EM programs with broader scopes. All outline programs with diverse curricula and varied educational and evaluative methods spanning from short courses to full residency programs, and they target learners from medical students and nurses to mid-level providers and physicians. Challenges of EM program development through partnerships include local adaptation of international materials; addressing the local culture(s) of learning, assessment, and practice; evaluation of impact; sustainability; and funding. Conclusions: Overall, this review describes a diverse group of programs that have been or are currently being implemented through partnerships. Additionally, it highlights several areas for program development, including addressing other topic areas within EM beyond trauma and ultrasound and evaluating outcomes beyond the level of the learner. These steps to develop effective programs will further the advancement of EM as a specialty and enhance the development of effective emergency care systems globally.

Essential medicines for emergency care in Africa.

OBJECTIVES: Essential medicines lists (EMLs) are efficient means to ensure access to safe and effective medications. The WHO has led this initiative, generating a biannual EML since 1977. Nearly all countries have implemented national EMLs based on the WHO EML. Although EMLs have given careful consideration to many public health priorities, they have yet to comprehensively address the importance of medicines for treating acute illness and injury. METHODS: We undertook a multistep consensus process to establish an EML for emergency care in Africa. After a review of existing literature and international EMLs, we generated a candidate list for emergency care. This list was reviewed by expert clinicians who ranked the medicines for overall inclusion and strength of recommendation. These medications and recommendations were then evaluated by an expert group. Medications that reached consensus in both the online survey and expert review were included in a draft emergency care EML, which underwent a final inperson consensus process. RESULTS: The final emergency care EML included 213 medicines, 25 of which are not in the 2017 WHO EML, but were deemed essential for clinical practice by regional emergency providers. The final EML has associated recommendations of desirable or essential and is subdivided by facility level. Thirty-nine medicines were recommended for basic facilities, an additional 96 for intermediate facilities (eg, district hospitals) and an additional 78 for advanced facilities (eg, tertiary centres). CONCLUSION: The 25 novel medications not currently on the WHO EML should be considered by planners when making rational formularies for developing emergency care systems. It is our hope that these resource-stratified lists will allow for easier implementation and will be a useful tool for practical expansion of emergency care delivery in Africa.

Defining quality indicators for emergency care delivery: findings of an expert consensus process by emergency care practitioners in Africa.

Facility-based emergency care delivery in low-income and middle- income countries is expanding rapidly, particularly in Africa. Unfortunately, these efforts rarely include measurement of the quality or the impact of care provided, which is essential for improvement of care provision. Our aim was to determine context-appropriate quality indicators that will allow uniform and objective data collection to enhance emergency care delivery throughout Africa. We undertook a multiphase expert consensus process to identify, rank and refine quality indicators. A comprehensive review of the literature identified existing indicators; those associated with a substantial burden of disease in Africa were categorised and presented to consensus conference delegates. Participants selected indicators based on inclusion criteria and priority clinical conditions. The indicators were then presented to a group of expert clinicians via on-line survey; all meeting agreements were refined in-person by a separate panel and ranked according to validity, feasibility and value. The consensus working group selected seven conditions addressing nearly 75% of mortality in the African region to prioritise during indicator development, and the final product at the end of the multiphase study was a list of 76 indicators. This comprehensive process produced a robust set of quality indicators for emergency care that are appropriate for use in the African setting. The adaptation of a standardised set of indicators will enhance the quality of care provided and allow for comparison of system strengthening efforts and resource distribution.

Preparing Emergency Physicians for Acute Disaster Response: A Review of Current Training Opportunities in the US.

Study Objective This study aimed to review available disaster training options for health care providers, and to provide specific recommendations for developing and delivering a disaster-response-training program for non-disaster-trained emergency physicians, residents, and trainees prior to acute deployment. METHODS: A comprehensive review of the peer-reviewed and grey literature of the existing training options for health care providers was conducted to provide specific recommendations. RESULTS: A comprehensive search of the Pubmed, Embase, Web of Science, Scopus, and Cochrane databases was performed to identify publications related to courses for disaster preparedness and response training for health care professionals. This search revealed 7,681 unique titles, of which 53 articles were included in the full review. A total of 384 courses were found through the grey literature search, and many of these were available online for no charge and could be completed in less than six hours. The majority of courses focused on management and disaster planning; few focused on clinical care and acute response. CONCLUSION: There is need for a course that is targeted toward emergency physicians and trainees without formal disaster training. This course should be available online and should utilize a mix of educational modalities, including lectures, scenarios, and virtual simulations. An ideal course should focus on disaster preparedness, and the clinical and non-clinical aspects of response, with a focus on an all-hazards approach, including both terrorism-related and environmental disasters.

Community-based perceptions of emergency care in Zambian communities lacking formalised emergency medicine systems.

BACKGROUND: In Zambia, an increasing burden of acute illness and injury emphasised the necessity of strengthening the national emergency care system. OBJECTIVE: The objective of this study was to identify critical interventions necessary to improve the Zambian emergency care system by determining the current pattern of emergency care delivery as experienced by members of the community, identifying the barriers faced when trying to access emergency care and gathering community-generated solutions to improve emergency care in their setting. METHODS: We used a qualitative research methodology to conduct focus groups with community members and healthcare providers in three Zambian provinces. Twenty-one community focus groups with 183 total participants were conducted overall, split equally between the provinces. An additional six focus groups were conducted with Zambian healthcare providers. Data were coded, aggregated and analysed using the content analysis approach. RESULTS: Community members in Zambia experience a wide range of medical emergencies. There is substantial reliance on family members and neighbours for assistance, commonly with transportation. Community-identified and provider-identified barriers to emergency care included transportation, healthcare provider deficiencies, lack of community knowledge, the national referral system and police protocols. CONCLUSIONS: Creating community education initiatives, strengthening the formal prehospital emergency care system, implementing triage in healthcare facilities and training healthcare providers in emergency care were community-identified and provider-identified solutions for improving access to emergency care.

Operationalising emergency care delivery in sub-Saharan Africa: consensus-based recommendations for healthcare facilities.

A major barrier to successful integration of acute care into health systems is the lack of consensus on the essential components of emergency care within resource-limited environments. The 2013 African Federation of Emergency Medicine Consensus Conference was convened to address the growing need for practical solutions to further implementation of emergency care in sub-Saharan Africa. Over 40 participants from 15 countries participated in the working group that focused on emergency care delivery at health facilities. Using the well-established approach developed in the WHO's Monitoring Emergency Obstetric Care, the workgroup identified the essential services delivered-signal functions-associated with each emergency care sentinel condition. Levels of emergency care were assigned based on the expected capacity of the facility to perform signal functions, and the necessary human, equipment and infrastructure resources identified. These consensus-based recommendations provide the foundation for objective facility capacity assessment in developing emergency health systems that can bolster strategic planning as well as facilitate monitoring and evaluation of service delivery.

An Analysis of the Relationship Between the Heat Index and Arrivals in the Emergency Department.

BACKGROUND: Heatwaves are one of the most deadly weather-related events in the United States and account for more deaths annually than hurricanes, tornadoes, floods, and earthquakes combined. However, there are few statistically rigorous studies of the effect of heatwaves on emergency department (ED) arrivals. A better understanding of this relationship can help hospitals plan better and provide better care for patients during these types of events. METHODS:  A retrospective review of all ED patient arrivals that occurred from April 15 through August 15 for the years 2008 through 2013 was performed. Daily patient arrival data were combined with weather data (temperature and humidity) to examine the potential relationships between the heat index and ED arrivals as well as the length of time patients spend in the ED using generalized additive models. In particular the effect the 2012 heat wave that swept across the United States, and which was hypothesized to increase arrivals was examined. RESULTS:  While there was no relationship found between the heat index and arrivals on a single day, a non-linear relationship was found between the mean three-day heat index and the number of daily arrivals. As the mean three-day heat index initially increased, the number of arrivals significantly declined. However, as the heat index continued to increase, the number of arrivals increased. It was estimated that there was approximately a 2% increase in arrivals when the mean heat index for three days approached 100°F. This relationship was strongest for adults aged 18-64, as well as for patients arriving with lower acuity. Additionally, a positive relationship was noted between the mean three-day heat index and the length of stay (LOS) for patients in the ED, but no relationship was found for the time from which a patient was first seen to when a disposition decision was made. No significant relationship was found for the effect of the 2012 heat wave on ED arrivals, though it did have an effect on patient LOS. CONCLUSION:  A single hot day has only a limited effect on ED arrivals, but continued hot weather has a cumulative effect. When the heat index is high (~90°F) for a number of days in a row, this curtails peoples activities, but if the heat index is very hot (~100°F) this likely results in an exacerbation of underlying conditions as well as heat-related events that drives an increase in ED arrivals. Periods of high heat also affects the length of stay of patients either by complicating care or by making it more difficult to discharge patients.

Perceptions of emergency care in Kenyan communities lacking access to formalised emergency medical systems: a qualitative study.

OBJECTIVES: We undertook this study in Kenya to understand the community's emergency care needs and barriers they face when trying to access care, and to seek community members' thoughts regarding high impact solutions to expand access to essential emergency services. DESIGN: We used a qualitative research methodology to conduct 59 focus groups with 528 total Kenyan community member participants. Data were coded, aggregated and analysed using the content analysis approach. SETTING: Participants were uniformly selected from all eight of the historical Kenyan provinces (Central, Coast, Eastern, Nairobi, North Eastern, Nyanza, Rift Valley and Western), with equal rural and urban community representation. RESULTS: Socioeconomic and cultural factors play a major role both in seeking and reaching emergency care. Community members in Kenya experience a wide range of medical emergencies, and seem to understand their time-critical nature. They rely on one another for assistance in the face of substantial barriers to care-a lack of: system structure, resources, transportation, trained healthcare providers and initial care at the scene. CONCLUSIONS: Access to emergency care in Kenya can be improved by encouraging recognition and initial treatment of emergent illness in the community, strengthening the pre-hospital care system, improving emergency care delivery at health facilities and creating new policies at a national level. These community-generated solutions likely have a wider applicability in the region.

Emergency care and health systems: consensus-based recommendations and future research priorities.

The theme of the 14th annual Academic Emergency Medicine consensus conference was "Global Health and Emergency Care: A Research Agenda." The goal of the conference was to create a robust and measurable research agenda for evaluating emergency health care delivery systems. The concept of health systems includes the organizations, institutions, and resources whose primary purpose is to promote, restore, and/or maintain health. This article further conceptualizes the vertical and horizontal delivery of acute and emergency care in low-resource settings by defining specific terminology for emergency care platforms and discussing how they fit into broader health systems models. This was accomplished through discussion surrounding four principal questions touching upon the interplay between health systems and acute and emergency care. This research agenda is intended to assist countries that are in the early stages of integrating emergency services into their health systems and are looking for guidance to maximize their development and health systems planning efforts.
