Obstetric hemorrhage in resource-limited locations: A quality improvement project after adoption of abdominopelvic compression devices

OBJECTIVE

To evaluate obstetric hemorrhage outcomes and present data specific to adoption of pneumatic circumferential abdominopelvic compression devices.

METHODS

Two resource-limited locations added low-cost pneumatic compression devices to their standard protocols for obstetric hemorrhage between 2010 and 2019. Providers in rural Nepal and Papua New Guinea used devices that incorporated a bicycle tube or soccer ball ("Ball and Binder") to provide abdominopelvic pressure after all available routine treatments had failed. Data were collected during the entire period as part of ongoing obstetric quality improvement. Data presented include obstetric event, etiology of bleeding, need for surgery, transfusion, transport, length of transports, maternal survival, and complications.

RESULTS

Circumferential abdominopelvic compression was used 106 times. The devices were used primarily after vaginal birth with atony, but also for obstetrical lacerations, miscarriages, and post-abortion bleeding. In all cases the bleeding stopped "promptly." All women survived, none required hysterectomy, and no complications were reported resulting from device use. Only 15 (14%) patients were transported to a referral hospital.

CONCLUSION

In this quality improvement project, obstetric hemorrhage was controlled when circumferential pressure was applied after usual care had failed.

Control of Pelvic Blood Flow Using a Novel Pneumatic Abdominal Binder

Background Obstetrical hemorrhage continues to be the leading cause of maternal death; additional means of treatment are needed to reach women who are currently not being saved. We developed the "Ball and Binder", an inexpensive and innovative pneumatic abdominal-pelvic compression device made with a cloth binder and soccer ball. Objective To measure the change in distal aortic blood flow before and after placement of the device. Method A comparative study was done on nine healthy volunteers measuring the flow in the distal aorta before and after placement of a pneumatic abdominal binder. Result Distal aortic flow decreased by over half when the device was inflated. Conclusion An inexpensive pneumatic external abdominal compression "Ball and Binder" device was able to decrease flow to the pelvis by over half. This provides an additional tool for rapid treatment of postpartum hemorrhage unresponsive to routine initial measures.

The Practitioner's Guide to Global Health: an interactive, online, open-access curriculum preparing medical learners for global health experiences

BACKGROUND

Short-term experiences in global health (STEGH) are increasingly common in medical education, as they can provide learners with opportunities for service, learning, and sharing perspectives. Academic institutions need high-quality preparatory curricula and mentorship to prepare learners for potential challenges in ethics, cultural sensitivity, and personal safety; however, availability and quality of these are variable.

OBJECTIVE

The objective of this study is to create and evaluate an open-access, interactive massive open online course (MOOC) that prepares learners to safely and effectively participate in STEGH, permits flexible and asynchronous learning, is free of charge, and provides a certificate upon successful completion.

METHODS

Global health experts from 8 countries, 42 institutions, and 7 specialties collaborated to create The Practitioner's Guide to Global Health (PGGH): the first course of this kind on the edX platform. Demographic data, pre- and posttests, and course evaluations were collected and analyzed.

RESULTS

Within its first year, PGGH enrolled 5935 learners from 163 countries. In a limited sample of 109 learners, mean posttest scores were significantly improved (p < 0.01). In the course's second year, 213 sampled learners had significant improvement (p < 0.001).

CONCLUSION

We created and evaluated the first interactive, asynchronous, free-of-charge global health preparation MOOC. The course has had significant interest from US-based and international learners, and posttest scores have shown significant improvement.

Global Emergency Medicine: A Review of the Literature From 2017

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners.

METHODS

This year, 17,722 articles written in three languages were identified by our electronic search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. Another two reviewers searched the gray literature, yielding an additional 11 articles. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles.

RESULTS

A total of 848 articles met our inclusion criteria and underwent full review. Sixty-three percent were categorized as emergency care in resource-limited settings, 23% as disaster and humanitarian response, and 14% as EM development. Twenty-one articles received scores of 18.5 or higher out of a maximum score 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed a Cohen's kappa of 0.344.

CONCLUSIONS

In 2017, the total number of articles identified by our search continued to increase. Studies and reviews with a focus on infectious diseases, pediatrics, and trauma represented the majority of top-scoring articles.

Global Emergency Medicine: A Review of the Literature From 2015

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners.

METHODS

This year 12,435 articles written in six languages were identified by our search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the gray literature. A total of 723 articles were deemed appropriate by at least one reviewer and approved by their editor for formal scoring of overall quality and importance. Two independent reviewers scored all articles.

RESULTS

A total of 723 articles met our predetermined inclusion criteria and underwent full review. Sixty percent were categorized as emergency care in resource-limited settings (ECRLS), 17% as EM development (EMD), and 23% as disaster and humanitarian response (DHR). Twenty-four articles received scores of 18.5 or higher out of a maximum score 20 and were selected for formal summary and critique. Inter-rater reliability between reviewers gave an intraclass correlation coefficient of 0.71 (95% confidence interval = 0.66 to 0.75). Studies and reviews with a focus on infectious diseases, trauma, and the diagnosis and treatment of diseases common in resource-limited settings represented the majority of articles selected for final review.

CONCLUSIONS

In 2015, there were almost twice as many articles found by our search compared to the 2014 review. The number of EMD articles increased, while the number ECRLS articles decreased. The number of DHR articles remained stable. As in prior years, the majority of articles focused on infectious diseases.

More than just a hobby: building an academic career in global emergency medicine

BACKGROUND

As the specialty of emergency medicine (EM) continues to spread around the world, a growing number of academic emergency physicians have become involved in global EM development, research, and teaching. While academic departments have always found this work laudable, they have only recently begun to accept global EM as a rigorous academic pursuit in its own right.

OBJECTIVE

This article describes how emergency physicians can translate their global health work into "academic currency" within both the clinician-educator and clinician-researcher tracks.

DISCUSSION

The authors discuss the impact of various types of additional training, including global EM fellowships, for launching a career in global EM. Clearly delineated clinician-researcher and clinician-educator tracks are important for documenting achievement in global EM.

CONCLUSIONS

Reflecting a growing interest in global health, more of today's EM faculty members are ascending the academic ranks as global EM specialists. Whether attempting to climb the academic ladder as a clinician-educator or clinician-researcher, advanced planning and the firm support of one's academic chair is crucial to the success of the promotion process. Given the relative youth of the subspecialty of global EM, however, it will take time for the pathways to academic promotion to become well delineated.

An inexpensive device to treat postpartum hemorrhage: a preliminary proof of concept study of health provider opinion and training in Nepal

Background

Obstetric hemorrhage remains the leading cause of maternal mortality in resource limited areas. An inexpensive pneumatic anti-shock garment was devised of bicycle tubes and tailored cloth which can be prepared from local materials in resource-limited settings. The main purposes of this study were: 1) to determine acceptability of the device by nurses and midwives and obtain suggestions for making the device more suitable for use in their particular work environments, 2) to determine whether a three hour training course provided adequate instruction in the use of this device for the application of circumferential abdominal pelvic pressure, and 3) determine production capability and cost in a resource-limited country.

Methods

Fifty-eight nurse and midwife participants took part in three sessions over eight months in Nepal. Correct device placement was assessed on non-pregnant participants using ultrasound measurement of distal aortic flow before and after device inflation, and analyzed using confidence intervals. Participants were surveyed to determine acceptability of the device, obtain suggestions for improvement, and to collect data on clinical use.

Results

Device placement achieved flow decreases with a mean of 39% (95% CI 25%-53%, p < 0.001) in the first session, 28% (95% CI 21%-33%, P < 0.001) after four months and 29% (95% CI 24%-34%, p < 0.001) at 8 months. All nurses and midwives thought the device would be acceptable for use in obstetric hemorrhage and that they could make, clean, and apply it. They quickly learned to apply the device, remembered how to apply it, and were willing and able to use the device clinically. Ten providers used the device, each on one patient, to treat obstetric hemorrhage after routine measures had failed; bleeding stopped promptly in all ten, two of whom were transported to the hospital. Production of devices in Kathmandu using local tailors and supplies cost approximately $40 per device, in a limited production setting.

Conclusions

Preliminary data suggest that an inexpensive, easily-made device is potentially an appropriate addition to current obstetric hemorrhage treatment in resource-limited areas and that further study is warranted.

Global health and emergency care: a resuscitation research agenda--part 2

At the 2013 Academic Emergency Medicine global health consensus conference, a breakout session to develop a research agenda for resuscitation was held. Two articles are the result of that discussion. This second article addresses data collection, management, and analysis and regionalization of postresuscitation care, resuscitation programs, and research examples around the world and proposes a strategy to strengthen resuscitation research globally. There is a need for reliable global statistics on resuscitation, international standardization of data, and development of an electronic standard for reporting data. Regionalization of postresuscitation care is a priority area for future research. Large resuscitation clinical research networks are feasible and can give valuable data for improvement of service and outcomes. Low-cost models of population-based research, and emphasis on interventional and implementation studies that assess the clinical effects of programs and interventions, are needed to determine the most cost-effective strategies to improve outcomes. The global challenge is how to adapt research findings to a developing world situation to have an effect internationally.

Executive summary: global health and emergency care-what do we need to know to address the burden of illness and injury?

Emergency physicians are uniquely poised to address challenges in health services, health care systems development and management, and emerging global disease burdens (both communicable and noncommunicable). This special issue of Academic Emergency Medicine reports the results of the 2013 consensus conference, which included eight focus areas that are intended to advance emergency care research. Advancing our understanding of cardiac and injury resuscitation, ethics of research, health systems development, and the education of our future leaders in global health will ultimately affect the populations of all nations across the globe.

Ethics in acute care research: a global perspective and research agenda

The 2013 Academic Emergency Medicine consensus conference focused on global health and emergency care research. One conference breakout session discussed research ethics and developed a research agenda concerning global acute care research ethics. This article represents the proceedings from that session, particularly focusing on ethical issues related to protecting human subjects while conducting acute care research. Protecting human research subjects from unnecessary risk is an important component of conducting ethical research, regardless of the research site. There are widely accepted ethical principles related to human subjects research; however, the interpretation of these principles requires specific local knowledge and expertise to ensure that research is conducted ethically within the societal and cultural norms. There is an obligation to conduct research ethically while recognizing the roles and responsibilities of all participants. This article discusses the complexities of determining and applying socially and culturally appropriate ethical principles during the conduct of global acute care research. Using case studies, it focuses both on the procedural components of ethical research conducted outside of "Western" culture and on basic ethical principles that are applicable to all human subjects research. This article also proposes specific research topics to stimulate future thought and the study of ethics in these complex circumstances.

Research priorities for data collection and management within global acute and emergency care systems

Barriers to global emergency care development include a critical lack of data in several areas, including limited documentation of the acute disease burden, lack of agreement on essential components of acute care systems, and a lack of consensus on key analytic elements, such as diagnostic classification schemes and regionally appropriate metrics for impact evaluation. These data gaps obscure the profound health effects of lack of emergency care access in low- and middle-income countries (LMICs). As part of the Academic Emergency Medicine consensus conference "Global Health and Emergency Care: A Research Agenda," a breakout group sought to develop a priority research agenda for data collection and management within global emergency care systems.

Making recording and analysis of chief complaint a priority for global emergency care research in low-income countries

The chief complaint is a patient's self-reported primary reason for presenting for medical care. The clinical utility and analytical importance of recording chief complaints have been widely accepted in highly developed emergency care systems, but this practice is far from universal in global emergency care, especially in limited-resource areas. It is precisely in these settings, however, that the use of chief complaints may have particular benefit. Chief complaints may be used to quantify, analyze, and plan for emergency care and provide valuable information on acute care needs where there are crucial data gaps. Globally, much work has been done to establish local practices around chief complaint collection and use, but no standards have been established and little work has been done to identify minimum effective sets of chief complaints that may be used in limited-resource settings. As part of the Academic Emergency Medicine consensus conference, "Global Health and Emergency Care: A Research Agenda," the breakout group on data management identified the lack of research on emergency chief complaints globally-especially in low-income countries where the highest proportion of the world's population resides-as a major gap in global emergency care research. This article reviews global research on emergency chief complaints in high-income countries with developed emergency care systems and sets forth an agenda for future research on chief complaints in limited-resource settings.

Education research: priority designs and common misperceptions

In this commentary, common misperceptions about education research, and specifically for emergency medicine education research, are addressed. Recommendations for designing and publishing high-quality projects are also provided.

A re-conceptualisation of acute spinal care

The emergency care of patients who may have spinal injuries has become highly ritualised. There is little scientific support for many of the recommended interventions and there is evidence that at least some methods now used in the field and emergency department are harmful. Since prospective clinical trials are not likely to resolve these issues I propose a reconceptualisation of spinal trauma to allow a more rational approach to treatment. To do this I analyse the basic physics, biomechanics and physiology involved. I then develop a list of recommended treatment variations that are more in keeping with the actual causes of post impact neurological deterioration than are current methods. Discarding the fundamentally flawed emphasis on decreasing post injury motion and concentrating on efforts to minimise energy deposition to the injured site, while minimising treatment delays, can simplify and streamline care without subjecting patients to procedures that are not useful and potentially harmful. Specific treatments that are irrational and which can be safely discarded include the use of backboards for transportation, cervical collar use except in specific injury types, immobilisation of ambulatory patients on backboards, prolonged attempts to stabilise the spine during extrication, mechanical immobilisation of uncooperative or seizing patients and forceful in line stabilisation during airway management.

Knowledge translation in international emergency medical care

More than 90% of the world population receives emergency medical care from different types of practitioners with little or no specific training in the field and with variable guidance and oversight. Emergency medical care is being recognized by actively practicing physicians around the world as an increasingly important domain in the overall health services package for a community. The know-do gap is well recognized as a major impediment to high-quality health care in much of the world. Knowledge translation principles for application in this highly varied young domain will require investigation of numerous aspects of the knowledge synthesis, exchange, and application domains in order to bring the greatest benefit of both explicit and tacit knowledge to increasing numbers of the world's population. This article reviews some of the issues particular to knowledge development and transfer in the international domain. The authors present a set of research proposals developed from a several-month online discussion among practitioners and teachers of emergency medical care in 16 countries from around the globe and from all economic strata, aimed at improving the flow of knowledge from developers and repositories of knowledge to the front lines of clinical care.

Diffusion of medical progress: early spinal immobilization in the emergency department

OBJECTIVES

To examine the spread of new techniques of spinal care through one state's emergency departments (EDs).

METHODS

This was a telephone survey of all 36 EDs in a single state. One physician from each ED was contacted and given a short structured survey instrument to determine when patients who arrived at the ED on backboards were removed from the backboards. Removal was classified as "immediate" if it was done before clinical or radiographic exclusion of cervical spine injury and "delayed" if it was done only after interpretation of any indicated diagnostic radiologic procedures. Further questions were asked to determine if all physicians in the group used the same technique and how this technique had been adopted.

RESULTS

In all but four hospitals, patients were removed from backboards in the same manner by all physicians, using a protocol or standard procedure. Fifteen of these did immediate and seventeen did delayed removal. In all but one case, the approach of immediate removal was initiated at the hospital by a physician trained or recently working at a university facility. Eight respondents stated that transport service requirements influenced their decision.

CONCLUSIONS

Although logic and the medical literature support removing all patients from a backboard immediately, physicians were unlikely to change their practice after their formal training had been completed until a new member of their group had done so.

The ED is an efficient place to treat ED patients

The purpose of this study was to determine what percentage of ED patients would be more efficiently treated in an offsite clinic. A stratified sample consisting of 650 ED visits were reviewed. Patient care was classified as more efficiently delivered in ED or clinic using prospectively developed criteria. Five hundred fifty-three (85%; 95% confidence interval [CI], 82-88%) visits met the definition of efficient ED utilization. One (0.15%; 95% CI, 0.01-0.99%) met the criteria for efficient clinic utilization. The other 96 (15%; 95% CI, 12-18%) failed to meet the definition of efficient for either site; 92 of these failed 2 or more clinic criteria. Only 25 (3.9%; 95% CI, 2.6-5.7%) were seen for nonacute problems. Few ED patients would be more efficiently seen in a clinic.

Discovery and optimization of 2-aryl oxazolo-pyrimidines as adenosine kinase inhibitors using liquid phase parallel synthesis

Adenosine kinase inhibition is an attractive therapeutic approach for several conditions for example, neurodegeneration, seizures, ischemia, inflammation and pain. Several nucleosidic and non-nucleosidic inhibitors are available. Using a virtual screening approach, we have discovered that 2-aryl oxazolo-pyrimidines are adenosine kinase inhibitors. Subsequent high throughput derivatization enabled the optimization of this new inhibitor chemotype resulting in highly potent derivatives. A variety of analogues were produced by applying liquid phase parallel synthesis to vary the 7-amino residues as well as the 2-aryl moiety.
