Abstract 57: A Crowdsourcing, Mobile Media, Challenge to Locate Automated External Defibrillators
Background: Automated external defibrillators (AEDs) are potentially life saving devices located in public locations, but are hard to find and rarely used. Crowdsourcing is increasingly being used to engage the public to participate in tasks that involve surveillance and mapping. Less is known however about using crowdsourcing for collecting important health data, like AED locations--where data validity is critical.
Methods: We used a crowdsourcing challenge to identify AEDs in Philadelphia. Participants in the challenge had to be >18 years of age. A custom mobile app was used to photograph AEDs and enter information about device location and access. Monetary prizes were offered to incentivize participation. Data validity was assessed by matching the mobile phones’ associated GPS coordinates of the photo with the GPS coordinates of the building location and/or comparing submitted data with AED location information collected pre-challenge.
Results: In 8 weeks, 1429 AEDs were submitted by 313 teams and individuals. Of participants providing demographic information (n=203), most were students 59(31%) or in the medical field 42(22%). Older participants (>41 years old) submitted more AEDs than younger participants (18-40 years of age) (respectively, 1025 vs. 404, p<.01). Most participants resided in Philadelphia 129 (64%), while others represented 10 states and 3 countries. More than half of the submissions represented unique AEDs 852(60%) in 528 buildings. AEDs were identified throughout the city, in 94% (46/49) of all Philadelphia zip codes in both public (59%) and private (41%) locations. Buildings (n=528) reported with AEDs were primarily: gyms 102 (19%), schools 85 (16%), and offices 57 (11%). Most submissions 1114 (75%) were validated with photo GPS coordinates matching the reported buildings GPS coordinates or by comparing submissions with data of AED locations identified pre-challenge.
Conclusion: Crowdsourcing is a feasible approach for identifying AED locations in an urban city. Further, mobile GPS technology can be used for validating health data provided by the public. Engaging the public as “citizen scientist” can help identify emergency health resources and needs and can simultaneously improve awareness about them.
