Identifying barriers for out of hospital emergency care in low and low-middle income countries: a systematic review.

BACKGROUND: Out-of-hospital emergency care (OHEC), also known as prehospital care, has been shown to reduce morbidity and mortality from serious illness. We sought to summarize literature for low and low-middle income countries to identify barriers to and key interventions for OHEC delivery. METHODS: We performed a systematic review of the peer reviewed literature from January 2005 to March 2015 in PubMed, Embase, Cochrane, and Web of Science. All articles referencing research from low and low-middle income countries addressing OHEC, emergency medical services, or transport/transfer of patients were included. We identified themes in the literature to form six categories of OHEC barriers. Data were collected using an electronic form and results were aggregated to produce a descriptive summary. RESULTS: A total 1927 titles were identified, 31 of which met inclusion criteria. Barriers to OHEC were divided into six categories that included: culture/community, infrastructure, communication/coordination, transport, equipment and personnel. Lack of transportation was a common problem, with 55% (17/31) of articles reporting this as a hindrance to OHEC. Ambulances were the most commonly mentioned (71%, 22/31) mode of transporting patients. However, many patients still relied on alternative means of transportation such as hired cars, and animal drawn carts. Sixty-one percent (19/31) of articles identified a lack of skilled personnel as a key barrier, with 32% (10/31) of OHEC being delivered by laypersons without formal training. Forty percent (12/31) of the systems identified in the review described a uniform access phone number for emergency medical service activation. CONCLUSIONS: Policy makers and researchers seeking to improve OHEC in low and low-middle income countries should focus on increasing the availability of transport and trained providers while improving patient access to the OHEC system. The review yielded articles with a primary focus in Africa, highlighting a need for future research in diverse geographic areas.

Nursing Perceptions of the Emergency Severity Index as a Triage Tool in the United Arab Emirates: A Qualitative Analysis.

INTRODUCTION: With emergency department crowding becoming an increasing problem across the globe, nursing triage to prioritize patients receiving care is ever more important. ESI is the most common triage system used in the United States and is increasingly used worldwide. This qualitative study that explores emergency nursing perceptions of the ESI identifies strengths, weaknesses, and barriers to implementation of the ESI internationally. METHODS: We conducted a cross-sectional qualitative analysis using semistructured interviews of 27 emergency triage nurses. Content analysis was performed by 2 independent coders, using NVivo software to identify and analyze important themes. RESULTS: Interview coding revealed 7 core themes related to use of the ESI (frequencies indicated in parentheses): ease of use (90), speed and efficiency (135), patient safety (12), accuracy and reliability (30), challenging patient characteristics (123), subjectivity and variability (173), and effect of triage system on team dynamics (100). Intercoder agreement was excellent (Cohen's unweighted kappa = 0.84). Subjectivity and variability in ESI score assignment consistently emerged in all interviews and included variability in number and use of resources, definition of "high risk," nursing experience, and subjectivity in pain assessment. DISCUSSION: Although emergency nurses perceive the ESI as easy to use, there are concerns about the subjectivity and variability inherent in the ESI that can lead to a functional lack of triage and a burden of undifferentiated ESI level 3 patients. These limitations in separating critically ill patients and in stratifying patients based on anticipated required resources points to the need for improvement in the ESI algorithm or a more objective triage system that can predict patient outcomes.

Reliability and validity of pediatric triage tools evaluated in Low resource settings: a systematic review.

BACKGROUND: Despite the high burden of pediatric mortality from preventable conditions in low and middle income countries and the existence of multiple tools to prioritize critically ill children in low-resource settings, no analysis exists of the reliability and validity of these tools in identifying critically ill children in these scenarios. METHODS: The authors performed a systematic search of the peer-reviewed literature published, for studies pertaining to for triage and IMCI in low and middle-income countries in English language, from January 01, 2000 to October 22, 2013. An updated literature search was performed on on July 1, 2015. The databases searched included the Cochrane Library, EMBASE, Medline, PubMed and Web of Science. Only studies that presented data on the reliability and validity evaluations of triage tool were included in this review. Two independent reviewers utilized a data abstraction tool to collect data on demographics, triage tool components and the reliability and validity data and summary findings for each triage tool assessed. RESULTS: Of the 4,717 studies searched, seven studies evaluating triage tools and 10 studies evaluating IMCI were included. There were wide varieties in method for assessing reliability and validity, with different settings, outcome metrics and statistical methods. CONCLUSIONS: Studies evaluating triage tools for pediatric patients in low and middle income countries are scarce. Furthermore the methodology utilized in the conduct of these studies varies greatly and does not allow for the comparison of tools across study sites.

Emergency response in resource-poor settings: a review of a newly-implemented EMS system in rural Uganda.

INTRODUCTION: The goal of an Emergency Medical Services (EMS) system is to prevent needless death or disability from time-sensitive disease processes. Despite growing evidence that these processes contribute significantly to mortality in low- and middle- income countries (LMICs), there has been little focus on the development of EMS systems in poor countries. Problem The objective of this study was to understand the utilization pattern of a newly-implemented EMS system in Ruhiira, Uganda. METHODS: An EMS system based on community priorities was implemented in rural Uganda in 2009. Six months of ambulance logs were reviewed. Patient, transfer, and clinical data were extracted and analyzed. RESULTS: In total, 207 cases were reviewed. Out of all transfers, 66% were for chief complaints that were obstetric related, while 12% were related to malaria. Out of all activations, 77.8% were for female patients. Among men, 34% and 28% were related to malaria and trauma, respectively. The majority of emergency transfers were from district to regional hospitals, including 52% of all obstetric transfers, 65% of malaria transfers, and 62% of all trauma transfers. There was no significant difference in the call to arrival on scene time, the time to scene or the scene to treatment time during the day and night (P > .05). Cost-benefit analysis revealed a cost of $89.95 per life saved with an estimated $0.93/capita to establish the system and $0.09/capita/year to maintain the system. CONCLUSION: Contrary to current belief, EMS systems in rural Africa can be affordable and highly utilized, particularly for life-threatening, nontrauma complaints. Construction of a simple but effective EMS system is feasible, acceptable, and an essential component to the primary health care system of LMICs.

Unintentional injuries: magnitude, prevention, and control.

The World Health Organization estimates injuries accounted for more than 5 million deaths in 2004, significantly impacting the global burden of disease. Nearly 3.9 million of these deaths were due to unintentional injury, a cause also responsible for more than 138 million disability-adjusted life years (DALYs) lost in the same year. More than 90% of the DALYs lost occur in low- and middle-income countries (LMICs), highlighting the disproportionate burden that injuries place on developing countries. This article examines the health and social impact of injury, injury data availability, and injury prevention interventions. By proposing initiatives to minimize the magnitude of death and disability due to unintentional injuries, particularly in LMICs, this review serves as a call to action for further investment in injury surveillance, prevention interventions, and health systems strengthening.

Risk factors for non-communicable diseases among older adults in rural Africa.

OBJECTIVE: To expand the evidence base on the prevalence of non-communicable disease (NCD) risk factors in rural Africa, in particular among older adults aged 50 and older. METHODS: Cross-sectional study in three rural sites in Malawi, Rwanda and Tanzania. One person was interviewed from each of 665 households selected through a stratified random sampling procedure across the three sites. The questionnaire included socio-demographic characteristics, smoking and alcohol intake as well as a food frequency questionnaire. RESULTS: Smoking rates among older men and women were higher than among adults under 50. While only 2.3% of women under 50 were current smokers, 21.0% of older women smoked (P<0.0001). Among men, 19.0% of men under 50 smoked versus 36.6% of older men (P=0.001). Alcohol consumption among older women aged 50 and older (45.0%) was more common (P=0.005) than among women under 50 (27.6%). Examining a set of five risk factors, more men aged 50 and older (49.5%) had two or more risk factors than men under 50 (25.5%) (P<0.0001). Similarly, 52.0% of women aged 50 and older had two or more risk factors, versus 24.1% of women under 50 (P<0.0001). CONCLUSION: Contrary to what is seen in developed country settings, this study reveals high rates of smoking and alcohol consumption among men and women aged 50 years and older in rural Africa that puts them at risk of NCDs. The health of older adults in rural Africa has been neglected, and these findings highlight the importance of reaching out to older adults with messaging regarding diet, smoking, alcohol use and general health.

Disseminating childhood home injury risk reduction information in Pakistan: results from a community-based pilot study.

BACKGROUND: Most childhood unintentional injuries occur in the home; however, very little home injury prevention information is tailored to developing countries. Utilizing our previously developed information dissemination tools and a hazard assessment checklist tailored to a low-income neighborhood in Pakistan, we pilot tested and compared the effectiveness of two dissemination tools. METHODS: Two low-income neighborhoods were mapped, identifying families with a child aged between 12 and 59 months. In June and July 2010, all enrolled households underwent a home hazard assessment at the same time hazard reduction education was being given using an in-home tutorial or a pamphlet. A follow up assessment was conducted 4-5 months later. RESULTS: 503 households were enrolled; 256 received a tutorial and 247 a pamphlet. The two groups differed significantly (p < 0.01) in level of maternal education and relationship of the child to the primary caregiver. However, when controlling for these variables, those receiving an in-home tutorial had a higher odds of hazard reduction than the pamphlet group for uncovered vats of water (OR 2.14, 95% CI: 1.28, 3.58), an open fire within reach of the child (OR 3.55, 95% CI: 1.80, 7.00), and inappropriately labeled cooking fuel containers (OR 1.86, 95% CI: 1.07, 3.25). CONCLUSIONS: This pilot project demonstrates the potential utility of using home-visit tutorials to decrease home hazards in a low-income neighborhood in Pakistan. A longer-term randomized study is needed to assess actual effectiveness of the use of allied health workers for home-based injury education and whether this results in decreased home injuries.

Childhood unintentional injuries: need for a community-based home injury risk assessments in pakistan.

Background. A substantial proportion of the annual 875,000 childhood unintentional injury deaths occur in the home. Very few printed tools are available in South Asia for disseminating home injury prevention information. Methods. Three tools were planned: an injury hazard assessment tool appropriate for a developing country setting, an educational pamphlet highlighting strategies for reducing home injury hazards, and an in-home safety tutorial program to be delivered by a trained community health worker. Results. The three tools were successfully developed. Two intervention neighborhoods in Karachi, Pakistan, were mapped. The tools were pretested in this local setting and are now ready for pilot testing in an intervention study. Conclusion. Planning for an innovative, community-based pilot study takes considerable time and effort in a low-income setting like Pakistan. The primary outcome of the pre-testing phase of the study was the development of three important tools geared for low-income housing communities in Pakistan.

Including emergency and acute care as a global health priority.

A recent important global meeting to set the international action agenda concerning non-communicable diseases (NCDs) failed to draw substantial attention from the emergency medical and surgical community. Advocacy efforts on the part of emergency clinicians should be increased to highlight the critical services we provide and create an approach to addressing NCDs with the most effective balance of preventive and acute care services. Acute care, which encompasses all frontline treatment services for sudden or unexpected injury or illness, can serve as a focal point for the development of the common language and body of research needed to draw the attention of global leaders and policy makers.
