A qualitative study of an undergraduate online emergency medicine education program at a teaching Hospital in Kampala, Uganda.

BACKGROUND: Globally, half of all years of life lost is due to emergency medical conditions, with low- and middle-income countries (LMICs) facing a disproportionate burden of these conditions. There is an urgent need to train the future physicians in LMICs in the identification and stabilization of patients with emergency medical conditions. Little research focuses on the development of effective emergency medicine (EM) medical education resources in LMICs and the perspectives of the students themselves. One emerging tool is the use of electronic learning (e-learning) and blended learning courses. We aimed to understand Uganda medical trainees' use of learning materials, perception of current e-learning resources, and perceived needs regarding EM skills acquisition during participation in an app-based EM course. METHODS: We conducted semi-structured interviews and focus groups of medical students and EM residents. Participants were recruited using convenience sampling. All sessions were audio recorded and transcribed verbatim. The final codebook was approved by three separate investigators, transcripts were coded after reaching consensus by all members of the coding team, and coded data were thematically analyzed. RESULTS: Twenty-six medical trainees were included in the study. Analysis of the transcripts revealed three major themes: [1] medical trainees want education in EM and actively seek EM training opportunities; [2] although the e-learning course supplements knowledge acquisition, medical students are most interested in hands-on EM-related training experiences; and [3] medical students want increased time with local physician educators that blended courses provide. CONCLUSIONS: Our findings show that while students lack access to structured EM education, they actively seek EM knowledge and practice experiences through self-identified, unstructured learning opportunities. Students value high quality, easily accessible EM education resources and employ e-learning resources to bridge gaps in their learning opportunities. However, students desire that these resources be complemented by in-person educational sessions and executed in collaboration with local EM experts who are able to contextualize materials, offer mentorship, and help students develop their interest in EM to continue the growth of the EM specialty.

Surviving sepsis in low-income and middle-income countries: new directions for care and research.

Sepsis is a disorder characterised by systemic inflammation secondary to infection. Despite recent progress in the understanding and treatment of sepsis, no data or recommendations exist that detail effective approaches to sepsis care in resource-limited low-income and middle-income countries (LMICs). Although few data exist on the burden of sepsis in LMICs, the prevalence of HIV and other comorbid conditions in some LMICs suggest that sepsis is a substantial contributor to mortality in these regions. In well-resourced countries, sepsis management relies on protocols and complex invasive technologies not widely available in most LMICs. However, the key concepts and components of sepsis management are potentially translatable to resource-limited environments. Health personnel in LMICs should be educated in the recognition of sepsis and the importance of early and appropriate antibiotic use. Simple and low-cost standardised laboratory testing should be emphasised to allow accurate diagnosis, prognosis, and monitoring of treatment response. Evidence-based interventions and treatment algorithms tailored to LMIC ecology and resources should thus be developed and validated.

HIV/AIDS, conflict and security in Africa: rethinking relationships.

The effect of conflict on HIV transmission and regional and global security has been the subject of much recent discussion and debate. Many long held assumptions regarding these relationships are being reconsidered. Conflict has long been assumed to contribute significantly to the spread of HIV infection. However, new research is casting doubt on this assumption. Studies from Africa suggest that conflict does not necessarily predispose to HIV transmission and indeed, there is evidence to suggest that recovery in the "post-conflict" state is potentially dangerous from the standpoint of HIV transmission. As well, refugee populations have been previously considered as highly infected vectors of HIV transmission. But in light of new investigation this belief is also being reconsidered. There has additionally been concern that high rates of HIV infection among many of the militaries of sub-Saharan Africa poses a threat to regional security. However, data is lacking on both dramatically elevated prevalence amongst soldiers and a possible negative effect on regional security. Nevertheless, HIV/AIDS remain a serious threat to population health and economic well being in this region. These issues are of vital importance for HIV programming and health sector development in conflict and "post-conflict" societies and will constitute formidable challenges to the international community. Further research is required to better inform the discussion of HIV, conflict, and security in sub-Saharan Africa.

A paradoxical peace: HIV in post-conflict states.

Conflict has traditionally been thought to contribute to the epidemic spread of HIV. New data call into question this assumption, and there is concern that the 'post-conflict phase' may be a particularly dangerous time for HIV transmission. The post-conflict phase is characterized by a potentially disastrous confluence of factors including demobilization of combatants, the presence of peacekeeping forces, the return of potentially infected soldiers and refugees, high-risk behaviours and persistent economic and social debilitation. These factors, along with the concentration of populations into cities and urban areas, may further increase the risk to these populations of HIV infection. Further research and study are required to adequately inform and address the issue of HIV transmission in post-conflict societies.

Anti-arrhythmic and vasopressor medications for the treatment of ventricular fibrillation in severe hypothermia: a systematic review of the literature.

OBJECTIVE: To determine the rate of return of spontaneous circulation (ROSC) in animal models performing resuscitation from induced ventricular fibrillation (VF) in severe hypothermia (<30 degrees C). MATERIALS AND METHODS: A medical literature database search from 1966 to present was performed identifying placebo controlled trials using anti-arrhythmic or vasopressor medications to treat ventricular fibrillation in the setting of severe hypothermia. RESULTS: 7 controlled studies were identified (n=117) testing 6 combinations of resuscitative medications. ROSC rates for treatment versus control groups were as follows: amiodarone (6% vs. 18%, p=0.6, n=34), bretylium (35% vs. 35%, p=1.0, n=40), intermediate- and high-dose epinephrine (adrenaline) (36% vs. 27%, p=1.0, n=22), vasopressin (60% vs. 0%, p<0.0001, n=39), vasopressin and amiodarone (0% vs. 0%, p=NS, n=11), low-dose epinephrine and amiodarone (91% vs. 30%, p=0.0075, n=21). Cumulatively, among all studies administering vasopressors, the rate of ROSC was 62% in treatment groups contrasted to 17% in control groups (p<0.0001, n=77). CONCLUSIONS: In controlled animal models of severe hypothermia, ROSC rates for induced ventricular fibrillation are higher with utilization of vasopressor medications. Current guidelines which recommend withholding these medications in the setting of hypothermic cardiac arrest should be re-evaluated.
