{{short description|Emergency First Aid Responder System Model}}

The '''Emergency First Aid Responder System Model''', or '''EFAR System Model''', was first published by Jared H. Sun and [[Lee A. Wallis]] in ''[[Emergency Medicine Journal]]'' in 2012, describing a system utilizing community members as first responders in low-resource settings to provide immediate basic care during medical emergencies until certified medical personnel arrive.<ref name=":0">{{Cite journal|lastlast1=Wallis|firstfirst1=Lee A.|last2=Sun|first2=Jared H.|date=2012-08-01|title=The emergency first aid responder system model: using community members to assist life-threatening emergencies in violent, developing areas of need|url=https://emj.bmj.com/content/29/8/673|journal=Emergency Medicine Journal|language=en|volume=29|issue=8|pages=673–678|doi=10.1136/emermed-2011-200271|issn=1472-0205|pmid=22011973|s2cid=23871044|url-access=subscription}}</ref> Since its creation, it has been deployed across twenty-three municipalities in [[South Africa]] and has been adapted for use in [[Zambia]].<ref>{{Cite journal|lastlast1=Wallis|firstfirst1=Lee A.|last2=Twomey|first2=Michele|last3=Shing|first3=Rachel|last4=Sun|first4=Jared H.|date=2014-01-01|title=A strategy to implement and support pre-hospital emergency medical systems in developing, resource-constrained areas of South Africa|url=https://www.injuryjournal.com/article/S0020-1383(12)00311-7/abstract|journal=Injury|language=English|volume=45|issue=1|pages=31–38|doi=10.1016/j.injury.2012.08.015|issn=0020-1383|pmid=22917929|url-access=subscription}}</ref><ref name=":1">{{Cite journal|lastlast1=Wallis|firstfirst1=Lee A.|last2=Kafwamfwa|first2=Muhumpu|last3=Cunningham|first3=Charmaine|last4=Pigoga|first4=Jennifer L.|date=2017-12-01|title=Adapting the emergency first aid responder course for Zambia through curriculum mapping and blueprinting|url=https://bmjopen.bmj.com/content/7/12/e018389 |journal=BMJ Open|language=en|volume=7|issue=12|pages=e018389|doi=10.1136/bmjopen-2017-018389|issn=2044-6055|pmid=29229657|pmc=5778307}}</ref>

== History ==

In low- and middle-income countries, trauma-related deaths disproportionately occur in the prehospital setting and are exacerbated by poorly resourced, poorly trained, or underdeveloped emergency medical services.<ref>{{Cite journal|date=2000-04-01|title=The global burden of injuries|url=https://ajph.aphapublications.org/doi/abs/10.2105/AJPH.90.4.523|journal=American Journal of Public Health|volume=90|issue=4|pages=523–526|doi=10.2105/AJPH.90.4.523|pmid=10754963|pmc=1446200|issn=0090-0036|last1=Krug|first1=E.

In 2009, Sun and Wallis began training community members as emergency first aid responders in [[Manenberg]], South Africa to treat the high levels of violence-related trauma present there,<ref name=":2">{{Cite web|url=https://www.stanford.edu/group/sjph/cgi-bin/sjphsite/no-time-to-waste-community-emergency-responder-programs-in-south-africa/|title=No Time to Waste: Community Emergency Responder Programs in South Africa|last=Holtzman|first=Jessie|date=2012-02-09|website=Stanford Journal of Public Health|language=en-US|access-date=2019-08-14}}</ref> as first responders had previously been suggested by the WHO as a possible alternative.<ref>{{Citecite journalweb|lastlast1=Sasser|firstfirst1=SV|last2=Kellerman|first2=A|date=2005|title=Prehospital Trauma Care Systems|url=https://www.who.int/violence_injury_prevention/media/news/04_07_2005/en/|archive-url=https://web.archive.org/web/20060106223322/http://www.who.int/violence_injury_prevention/media/news/04_07_2005/en/|url-status=dead|archive-date=January 6, 2006|journalpublisher=The World Health Organization|volume=|pages=|via=World Health Organization}}</ref> They found community members were dispersed and able to arrive on scene sooner than professional emergency medical providers.<ref name=":0" /> Experiencing success, they realized that using community members who want to assist was a possibility worth exploring.<ref>{{Cite web|url=https://harriscpd.co.uk/wordpress/archives/5949|title=Podcast#21(Part2): “Africa’s"Africa's Best Practice?”" « HarrisCPD|language=en-US|access-date=2019-08-14}}</ref> The EFAR system model was then designed to integrate into pre-existing or support the development of formal emergency care systems, or even serve as the foundation upon which a new emergency care system could be built.<ref name=":0" /> However, the EFAR system model has primarily served to alleviate the inconsistent and unreliable response times of ambulances and other emergency services in the Cape Town area.<ref name=":2" />

EFAR systems were implemented in two rural regions of Zambia in 2015, though no refinements were made to the course for the new setting.<ref name=":1" />

In 2022, the EFAR system of South Africa joined the [[Global Prehospital Consortium]].<ref>{{Cite journal |last=Delaney |first=Peter G. |last2=De Vos |first2=Simonay |last3=Eisner |first3=Zachary J. |last4=Friesen |first4=Jason |last5=Hingi |first5=Marko |last6=Mirza |first6=Usama Javed |last7=Kharel |first7=Ramu |last8=Moussally |first8=Jon |last9=Smith |first9=Nathanael |last10=Slingers |first10=Marcus |last11=Sun |first11=Jared |last12=Thullah |first12=Alfred Harun |date=2025-01-01 |title=Challenges, opportunities, and priorities for tier-1 emergency medical services (EMS) development in low- and middle-income countries: A modified Delphi-based consensus study among the global prehospital consortium |url=https://www.sciencedirect.com/science/article/pii/S0020138324002092 |journal=Injury |volume=56 |issue=1 |pages=111522 |doi=10.1016/j.injury.2024.111522 |issn=0020-1383|doi-access=free }}</ref>
