Eifo Defi? (Where is that defibrillator at?) is a private, volunteer-run Israeli initiative that crowdsources the mapping and public availability of semi-automatic defibrillators (AEDs) installed in Israel's public spaces. The project includes a free app for smartphones and web browsers that can guide users to the nearest AED via GPS and compass, and a public registry of AED locations updated daily from user reports and released as an open-licensed map layer.

Eifo Defi? was set up to chart the AED units deployed across Israel and thus make them easier to reach during a cardiac emergency, with the aim of improving survival rates and reducing neurological damage in cases of out-of-hospital cardiac arrest[1].

History

[edit]

The initiative was originally launched under the name "Med-Man" within Ben-Gurion University's "Students Leading Public-Sector Innovation 2.0" competition, run in partnership with Google, during the first year of medical studies of Noam Hadar, Dr Rotem Tal-Ben-Yishai, Dr Asil Mahamid, and Dr Ariel Hasidim. The project won second place with an Android-based smartphone app.[2] After the competition, it was kept alive as a private, volunteer-run effort—initially by all the original team members and later by Dr Ariel Hasidim.

In March 2017, the first browser-based version of the Efio Defi? app was launched.

In December 2017, the initiative was awarded the Aviel Ron Research and Development grant from the Survey of Israel's Chief Scientist. During the grant period an iPhone version of the smartphone app was developed.[3] In October 2018, a progress report was presented under the Chief Scientist at the plenary conference of the Inter-Ministerial GIS Committee, noting roughly 1,000 devices registered.[4]

In August 2019, the project secured funding for a second time—this time through Ben-Gurion University's "Cactus Fund".[5]

Mapping

[edit]

Eifo Defi? was established on the premise that, in Israel, there is a gap between the number of AEDs installed in public spaces—whether under the Public Defibrillator Placement Law or for other reasons—and the number of times they are actually used. The root cause, the team argues, is accessibility: without a proper register of device locations and availability, the units are effectively out of reach when needed. Reinforcing this assumption, studies show that in out-of-hospital cardiac arrest, the distance from the incident scene to the nearest AED is the factor most strongly linked to 30-day survival.[6]

Crowdsourced AED registration in Eifo Defi? takes place inside the free smartphone app, after the user signs in. Once a user shares a device, the record is verified by a human reviewer before appearing on the public map, and the registry is refreshed daily. A new entry can be posted only when the user is physically near the AED so it can be photographed; during the photo the phone's GPS supplies a coordinate that pins the device on the map. Besides adding new devices, users can report detail changes or updates, flag unavailable units for removal, and upload a new photo.

The Eifo Defi? map holds thousands of entries. Some AEDs were installed because the law requires any establishment that serves more than 500 people a day to provide one. Others were placed voluntarily: many units were located at private homes, apartment blocks, synagogues, and mosques, while additional devices have been deployed in public areas by local authorities, the national lottery (Mifal HaPayis), and emergency-service organizations.[7]

Accessibility

The information is distributed openly so that anyone can learn where nearby AED units are located for use during a cardiac-arrest incident. It is likewise available to emergency-services dispatchers, who can guide callers on retrieving the nearest device and bringing it to the scene until responders arrive.[1]

Accessibility inside Eifo Defi?

[edit]

The AED register is presented as a map layer in the smartphone app and when the browser version is opened on a phone. Smartphone users can trigger turn-by-turn navigation to the nearest device through a dedicated engine that incorporates a compass. This browser-based navigation link was designed so it can be sent in a simple message to a bystander at a cardiac event; with one tap, the recipient is routed to the closest unit.[1] In emergencies, this feature can also help bystanders who come upon an out-of-hospital cardiac arrest locate an AED. Research shows that when bystanders spontaneously fetch a defibrillator on their own, a patient's odds of survival double compared with cases where only professional crews are dispatched.[8]

Third-party accessibility

[edit]

Additionally, the device register collected by Eifo Defi? is shared with third parties through several channels: an up-to-date CSV download on the project website; as a layer on the national government mapping service;[9] on the government open-data portal;[10] via a dedicated API; and through several ESRI GIS services.[11] All copies distributed through these channels are released under the open ODC-By v1.0 license.[12]

The Eifo Defi? AED register is used by the dispatch centers of the emergency services Magen David Adom (MDA)[13] and United Hatzalah, and is integrated into several municipal GIS systems, including those of Beersheba,[14] Lod,[15] Rishon LeZion[16] and Kiryat Malakhi.[17]

Activity

[edit]

In February 2022, the initiative took part in the annual national AED-awareness day "Samim Lev" ("Paying Attention") alongside Lihi Korin, Sapir Aluk, and Gal Peled, in cooperation with the Israel Heart Society, Magen David Adom, Mifal HaPayis, and the Center for Local Government.[18] As part of the awareness day, the Knesset Health Committee held a discussion on placing resuscitation devices in public spaces and on initiatives to promote the deployment and use of defibrillators, during which the project was mentioned.

Abuse

[edit]

In January 2022, prosecutors filed an indictment against a 33-year-old resident of Kfar Yona for stealing defibrillators. The charge sheet says he used the Eifo Defi? app to pinpoint the devices, concentrating his thefts in rural areas.
